A BUOY APPARATUS AND THE CONTROL SYSTEM
FIELD OF THE INVENTION
[0001] The present disclosure relates generally to marking an
underwater object, in particular to a buoy apparatus a buoy control system,
and a method for identifying an underwater object.
BACKGROUND
[0002] A buoy apparatus is used for marking the position of
underwater objects and/or pulling the objects up with a connected rope.
Existing buoy apparatuses mainly comprise two portions: one above water
for indicating the position of an underwater object and the other part is
under the water for connecting or pulling underwater object. The above
water portion may be a buoy with a color; the underwater portion comprises
an object and a rope with one end connecting to the object. The rope with
the other end connects to the buoy. To retrieve the underwater object, first
thing to do is to locate the buoy and then pull the rope out of the water.
[0003] However, when these buoy apparatuses are densely distributed
in the ocean, the ropes form net-like obstacles that pose a threat to the
lives
of marine organisms. For instance, marine organisms may be entangled in
the net-like obstacles from which they cannot escape and may die.
SUMMARY OF THE INVENTION
[0004] The embodiments of the present invention provide a buoy
apparatus and a buoy control system for marking the underwater object. The
ropes of the buoy apparatus and the buoy control system only extends to
the surface of the water only triggered by instructions.

[0022] Comparing with the prior art, the technical solution of the
present invention has a first microprocessor module of the spool control
device capable to generate a decoupling instruction. Following the
instruction, a decoupling control module instructs a retractable head of a
decoupling electric motor device in the spool structure to extend or retract.
When the retractable head extends, the first spool flange is engaged with it.
The spool structure is locked. When the retractable head retracts, the first
spool flange is released. The spool structure is unlocked. Meanwhile, since a
rope connects with a buoy, buoyancy pulls the rope from the spool, thereby,
bringing the entire buoy apparatus floating. Since the rope initially winds or
coiled around the spool, the technical solution of the present invention has
no rope suspending in water. Thus, it solves the problem from the prior art
that buoys with ropes suspending in water pose a threat to the survival of
marine organisms.

DESCRIPTION OF EXAMPLE EMBODIMENTS
[0044] Referring to the drawings, the embodiments of the present
invention are further in detail illustrated below. It is understood that the
specific embodiments described herein are only the explanations to
associated inventions, rather than restrictions to the present invention. In
addition, to easily describe, only the parts related to the invention are
shown
in the drawings.
[0045] It needs to be noted, in the absence of conflict, the
embodiments and the embodiment features of the present invention can be
combined with each other. Referring to the drawings and the embodiments,
the present invention is in detail illustrated below.
[0046] To solve the problem that buoys with ropes pose a threat to
the
survival of marine organisms, the embodiments of the present invention
provide a buoy apparatus and a buoy control system.
[0047] In the example of Figures 1A and 1B, a buoy apparatus 1 may
be used underwater. The buoy apparatus 1 may include a spool control
device 11, a spool structure 12, and a buoy 13. As illustrated in the example
of Figure 1B, the buoy 13 may be secured to an end of a string, rope, or
strip, which is winded on the spool structure 12. The buoy 13 may be made
R&M REF: 54401-3001
CA 3038171 2019-03-27

by materials afloat in the water, such as polyethylene. The other end of the
rope may be secured to the spool structure 12 (not shown). The spool
structure 12 and the spool control device 11 may be installed on a rack 99.
The rack 99 is configured to permit the spool structure 12 rotate when the
spool control device 11 unlock the spool structure 12 and when the buoy 13,
due to the buoyance of the water, raises toward the surface of the water. In
the example of Figure 1B, the rack 99 has a height that provides a free
space between the bottom of the spool structure 12 and the base of the rack
99.
[0048] In some examples, an object to be identified in the water, such
as a lobster trap cage, may be secured to the base 128 (Figure 1B) of the
buoy apparatus 1, and the object and the buoy apparatus 1 may be thrown
into the water, such as from a boat. The object and the buoy apparatus 1
sink into the water due to the gravity. When the spool control device 11
unlock the spool structure 12 in the water, the buoy 13 and the end of the
rope raise toward the water, and the raise of the rope causes the spool
structure 12 to rotate to release the rope in the water until the buoyance of
the buoy 13 is substantially the same as the gravity of the rope or of the
buoy apparatus 1. In the example of Figure 2, the spool control device 11
may include a decoupling electric motor device 124 and a control module
11A. The control module 11A may include a first microprocessor module 111
for generating decoupling instructions, and a decoupling control module 112
electrically connecting to the first microprocessor module 111 for receiving
the instructions from the first microprocessor module 111. In response to
the instructions received from the first microprocessor module 11, the
decoupling control module 112 may selectively actuate the decoupling
electric motor device 124 of the spool structure 12 to lock or unlock the
spool structure 12.
[0049] In some examples, the control module 11A may also include a
first communication interface module 113 and a first communication circuit
115. The first communication interface module 113 allows the spool control
device 11 to communicate with other communication devices by using a
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 9 -
communication device 14 in Figure 5 to be described below. The
communication device 14 may include Sonar, laser communication devices.
The first communication circuit 115 may process the communication signals
generated from the spool control device 11a, such as by the microprocessor
module 111, or signals received by the first communication interface module
113. For example, the first communication circuit 115 may modulate,
demodulate, encode or decode the signals.
[0050] In some examples, the spool control device 11 may only include
the control module 11A, and the decoupling electric motor device 124 may
be a stand-alone device mounted on the rack 99.
[0051] As shown in the example of Figure 2, the spool control device
11 may also include a battery module 114. The battery module 114
electrically connects to and supplies power to the first microprocessor
module 111. The battery module 114 may be a lithium battery module or
other power supply modules.
[0052] Optionally, in order for the buoy apparatus 1 to be more
accessible in use, as illustrated in Figure 2, the spool control device 11 may
also include a LED indication circuit 116, press-key interface module 117 and
a liquid crystal circuit 118. The LED indication circuit 116, the press-key
interface module 117 and the liquid crystal circuit 118 are respectively
connected to the first microprocessor module 111. The LED indication circuit
116 may be used to indicate the operational status, such as hibernate, work,
or triggered, of the microprocessor module 111. The press-key interface
module 117 may be used for a user to manual configure parameters of the
spool control device 11. For example when the buoy apparatus 1 is not in
the water, a user may configure the time, such as 12 hours, for the
microprocessor module to trigger decoupling control module 112, which may
in turn trigger the decoupling electric motor 124 to release the buoy 13
when the time is expired. The liquid crystal circuit 118 may be display the
information of the spool control device 11, such as remaining life of the
battery module 114. Certainly, these modules, circuits and so on are only as
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 10 -
the specific examples. In actual, other functional modules or circuits may be
added based on requirements, which is not described herein.
[0053] In the example of Figure 3A, the spool structure 12 may
include
a plurality of connecting rods 121 and a first and second spool flanges 122
and 123. The connecting rods 121 have two ends, one end of each
connecting rod 121 being securely connected on the first spool flange 122,
the other end of each connecting rod being securely connected on the
second spool flange 123. Figure 3B illustrates an example that the spool
structure 12 and the spool control device 11 are mounted on the rack 99.
[0054] As depicted in Figure 4, a buoy 13 has a rope fixing ring 131 on
the bottom for securely connecting to an end of the rope or string. The buoy
13 may be connected to a rope through the rope fixing ring 131. The other
end of the rope may be securely connected to the spool structure 12, such
as to one of the connecting rods 121. A rope or string tied to a buoy ring 131
may be winded on the connecting rods and between the first and second
spool flanges 122 and 123.
[0055] The decoupling electric motor device 124 may connect to an
outer side of the first or second spool flange 122 or 123. In some examples,
the decoupling electric motor device 124 may connect to a central shaft 900
of the spool structure 12 at the outer sider of the first spool flange 122.
The
first spool flange 122 is engaged with a retractable head 126 of the
decoupling electric motor device 124 when the head extends to the first
spool flange 122, and the spool flanges 122 and 123 is fixed and not
rotatable in the water. When the retractable head of the decoupling electric
motor device 124 retracts from the first spool flange, the first spool flange
122 is released and when the buoy 13 raises toward the surface of the
water, the spool flanges 122 and 123 is rotatable in the water to unwind the
rope. When the first spool flange 122 is released from the retractable head
126, in response to the buoyance generated by the buoy 13, the buoy 13
pulls the rope with one end fixed on the rope fixing ring 131 and the rope
raises towards the surface of the water with the buoy 13. The entire buoy
R&M REF: 54401-3001
CA 3038171 2019-03-27
-11 -
apparatus 1 rises by buoyancy until the buoy 13 is above the surface of the
water.
[0056] The retractable head 126 of the decoupling electric motor
device 124 may be triggered to retract by the first microprocessor module
111 in several manners. For example, the timer set by the microprocessor
module 111 as described above is expired; in response to the instructions of
the user to release the buoy 13 provided by the communication device 14 in
Figure 5, the communication interface module 113 receives the instructions;
the remaining life of the battery module 114 is low, such as in 10 days. In
these examples, the first microprocessor module 111 may instruct the
decoupling control module 112 to retract the retractable head 126. In
response, the decoupling electric motor device 124 may be actuated to
retract the retractable head 126. The decoupling electric motor device 124
may have a power of 16 watts, and may be a relay control motor or a driver
motor. The decoupling electric motor device 124 may source power form
the battery module 114.
[0057] In some examples, the first microprocessor module 111 may
generate decoupling instructions at a predetermined time, for example, a
time set by a user based on the actual needs, such as 12 hours, one day, or
one week before the buoy apparatus 1 is placed into the water. The
microprocessor module 111 may be a processor or a Central Processing unit
(CPU). In some examples, the first microprocessor module 111 may have a
timer. When the timer reaches the pre-determined time, the first
microprocessor module 111 may generate one or more decoupling
instructions to cause the decoupling control module 112 to decouple the
retractable head 126. In some examples, the first microprocessor module
111 may monitor the status of the battery module 114, and may also
generate a decoupling instruction when the battery module 114 is in a low-
battery state or when an alarm of a low-battery is triggered.
[0058] Optionally, a user may also manually cause the first
microprocessor module 111 to generate a decoupling instruction, for
example, by pressing a remote control button of a communication device. In
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 12 -
the example of Figure 5, the buoy apparatus 1 may further include a first
communication device 14 mounted to the spool control device 11 for this
purpose. The communication device 14 may include Sonar, laser
communication devices. As described in the example of Figure 2, the spool
control device 11 may also include the first communication interface module
113. The first communication interface module 113 may electrically connect
with the first communication device 14. As such, the first communication
device 14 and the first microprocessor module 111 may wiredly or wirelessly
communicate with each other via the first communication interface module
113. For example, after a person on a boat places an object, such as a
lobster trap cage, and the buoy apparatus 1 into the water, the person may
record the GPS location of the object and the and the buoy apparatus 1. The
retractable head 126 is in a lock state (Figure 88) when the buoy apparatus
land the object are placed into the water, and remain in the lock state until
the retractable head 126 is retracted to an unlocked state (Figure 8A).
Figure 8C is an example showing the buoy apparatus 1 is in an unlocked
state. The person may come back to the same location after a period of
time, such as one week. The person may use a communication device on the
boat, such as a Sonar or laser device, to send instructions to the
communication device 14 underwater. The first communication device 14
may receive user instructions from the communication device, and may
forward the instructions to the first communication interface module 113,
and the first communication interface module 113 may send the instructions
to the first microprocessor module 111. In response to the instructions
received from the first communication device 14, the first microprocessor
module 111 instructs the decoupling control module 112 to decouple the
rope from the spool structure 12. In response, the decoupling control module
112 actuate retractable head 126 of the decoupling electric motor device 124
to unlock the spool structure 12 so that the buoy 13 may raise toward the
surface of the water. The buoy 13, the buoy device 1, and the object may
be retrieved out from the water, for example, by pulling the rope by a
person on a boat.

CA 3038171 2019-03-27
- 13 -
[0059] In addition, as underwater application of the buoy apparatus
1
may limit the communication capability of the first communication device 14,
such as reduced communication distance, and increased channel loss and
power consumption, the first communication device 14 may be a transducer
with low power consumption and anti-interference capabilities, for example
by using Sonar communication system. When the first communication device
14 is a transducer, the first communication interface module 113 may be a
transducer interface module.
[0060] Figure 6 illustrates an example of a circuit of the
decoupling
control module 112. The first microprocessor module 111 controls a relay of
A PD8 voltage of the first microprocessor module 111 to be ON or OFF. When
the relay output from PD8 voltage is ON, the decoupling electric motor
device 124 is powered on, and the retractable head of the decoupling electric
motor device 124 retracts, the retractable head of the decoupling electric
motor device 124 and the first spool flange 122 are separated from each
other, and the spool structure 12 is unlocked and the buoy 13 is released
from the spool structure 12. Accordingly, the buoy 13 pulls the rope fixed on
the rope fixing ring 131 and the entire buoy apparatus 1 rises by buoyancy
until the buoy 13 is above the surface of water. When the relay output from
PD8 voltage is OFF, the decoupling electric motor device 124 is powered off,
and the retractable head of the decoupling electric motor device 124
extends, the retractable head of the decoupling electric motor device 124
and the first spool flange 122 are engaged with each other, and the spool
structure 12 is locked as illustrated in Figure 8B and the ropes are winded on
the spool and buoy 13 is pulled to the spool structure from the surface of the
water.
[0061] In some examples, to avoid the buoy 13 to be stuck between
the first and second flanges 122 and 123, a portion, such as 20 cm or less,
of the rope connecting to the rope fixing ring 131 may be pulled out from the
spool structure 12 to leave a distance between the buoy 13 and the spool
structure 12. A shorter distance works better to reduce the interference of
the rope to the safe of marine organisms.
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 14 -
[0062] Optionally, to make the buoy 13 more obvious and convenient
for user's searching, In the example of Figure 4, the buoy 13 may include a
flash cone barrel 137, a wind vane 138 and so on. The buoy 13 may also
comprise other suitable structures to clearly identify the buoy 13 on the
surface of the water.
[0063] Figure 7 is a flow chart showing an exemplary operation
process
of the buoy apparatus 1. At step701, the first microprocessor module 111 in
the spool control device 11 generates decoupling instructions. In some
examples, the first microprocessor module 111 generates a decoupling
instruction based on a pre-set time on a timer. It may also generate a
decoupling instruction manually from users through the first communication
device 14 as described above. Certainly, there are other methods to
generate decoupling instructions, which is not described herein.
[0064] At step 702, decoupling instructions generated by the first
microprocessor module 111 are transmitted to the decoupling control
module 112 from the first microprocessor module 111. The decoupling
instructions may be a high or low voltage level signal, such as a Transistor-
transistor logic (TTL) signal. In some examples, the first microprocessor
module 111 through controlling PD8 pin voltage may send decoupling
instructions or TTL signals to the decoupling control module 112.
[0065] At 5tep703, the decoupling control module 112, in response to
the decoupling instructions received from the first microprocessor module
111, may trigger the decoupling process, for example, by actuating the
decoupling electric motor device 124 on the spool structure 12.
[0066] At step 704, when the decoupling electric motor device 124
may control a retractable head to retract, the head and the first spool flange
122 are separated and the spool structure 12 is unlocked. When the spool
structure 12 is unlocked, in response to an external force, such as buoyancy,
the spool structure 12 may rotate to extend or unwind the rope.

[0067] At step 705, the buoy 13 may pull the rope with one end fixed
on the rope fixing ring 131, and the entire buoy apparatus 1 and the object
rises by buoyancy until the buoy 13 is up to the surface of water.
[0068] The entire buoy apparatus 1, including the spool structure 12,
and the object may be retrieved from the water and the rope may be winded
on the spool structure 12 by rotating the spool structure with the handle 125
(Figure 8A).
[0069] By using the first microprocessor module 111 to generate a
decoupling instruction for controlling a spool control device 11, a decoupling
control module 112 instructs a retractable head of a decoupling electric
motor device 124 in the spool structure 12 to extend the rope. When the
retractable head extends, the first spool flange is engaged with it. The spool
structure 12 is locked and the spool structure 12 is not rotatable. When the
retractable head retracts, the first spool flange is released, the spool
structure 12 is unlocked. The spool structure 12 is rotatable in response to
an external force, such as a buoyance generated by the buoy 13. Meanwhile,
since a rope connects with a buoy 12, buoyancy pulls the rope from the
spool structure 12, thereby, bringing the entire buoy apparatus 1 and the
object secured on the base 128 floating. Since the rope initially winds around
the spool structure 12 before the spool structure 12 is unlocked, there is no
rope suspending in the water. Thus, the ropes only suspend in the water
when the spool structure 12 is unlocked under instructions or based on
needs. As such, with this mechanism, a threat to the survival of marine
organisms is significantly reduced by reducing the time of suspending the
ropes in the water.
[0070] Another embodiment of the present invention further provides a
buoy apparatus 1, this buoy apparatus 1 is substantially same as the one
depicted from Figure 1 to Figure 6. The difference is: as depicted in Figure
8A, a spool structure 12' may also include a manual spin handle 125 and a
rack 99. The manual spin handle 125 may connect to the outer sider the
second spool flange 123. The rack 99 is set at the outer side of the first
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 16 -
spool flange 122 and may connect to the decoupling electric motor device
124.
[0071] By providing a manual spin handle 125 and a rack 99 to the
spool structure 12, users can easily rewind the rope around the connecting
rods 121 with the manual spin handle 125 after the buoy apparatus 1 is
pulled out of the water. Thereby, this buoy apparatus 1 provided by the
embodiment of the present invention is further convenient for users.
[0072] Figure 9 is another embodiment of the present invention
providing a buoy apparatus 1. The buoy apparatus 1 is substantially same as
the one depicted from Figure 1 to Figure 6, except that the buoy 13 may
also internally include a second microprocessor module 132, a battery
module 133 connecting to the second microprocessor module 132, a first
communication module 134 connecting to the second microprocessor module
132 and a subscriber identification module (SIM) slot 135 connecting to the
first communication module 134.
[0073] In the embodiment in Figure 9, the buoy apparatus 1 may have
a positioning function. Specifically, the second microprocessor module 132 of
the buoy 13 generates positioning information for example, by a GPS sensor,
as well as transmits the positioning information to users via a SIM card on
the SIM slot 135 and the first communication module 134. After a buoy
apparatus 1 is floating on the surface of the water, buoy apparatus 1 floats
with the current of the water and may get lost. With the positioning function
integrated in the buoy apparatus 1, it does not get lost after floating up to
the surface of water. Further, since the buoy 13 is provided with a SIM slot
135 for receiving a SIM card, the buoy 13 directly transmits, such as via a
public land mobile network, the position information to the corresponding
user's mobile phone, mobile terminal devices and so on. There is no need for
users to have an additional communication device. In some examples, the
SIM slot 135 may also be substitute with a wireless transmitter that may
wirelessly communicate, such as the position information of the buoy 13,
with a wireless receiver from the user side.

[0074] Further, since the buoy apparatus 1 provided by the
embodiments of the present invention is applied underwater, to extend the
power supply period of the battery module 133 as depicted in Figure 9, the
buoy 13 is internally set with an automatic power-on module 136. One end
of the automatic power-on module 136 connects to the battery module 133
and another connects to the second microprocessor module 132. In some
examples, the power-on module 136 has a pressure sensor and is configured
to electrically connect the battery module 133 with the second
microprocessor module 132, when the pressure of the water is less than a
threshold value, for example at a pressure level when the buoy 13 raises
above the water. As such, the battery module 133 only supply power to the
second microprocessor module 132 when the buoy 13 is close to or above
the surface of the water. In some examples, the power-on module 136 may
include a circuit breaker which is configured to electrically connect the
battery module 133 with the second microprocessor module 132 after the
breaker is merged in the water for a given period.
[0075] It needs to be noted, the embodiment does not limit the
specific
structure of the automatic power-on module 136. In actual, the automatic
power-on module 136 may be designed with any achievable structure.
[0076] Figure 10 illustrates another exemplary configuration of the
automatic power-on module 136. In the example of Figure 10, the automatic
power-on module 136 may include a protective cover 1361; the protective
cover 1361 is externally set up with two terminals 1362. The two terminals
1362 respectively connect to the positive electrode of the battery module
133 and to the positive electrode of the second microprocessor module 132.
The protective cover 1361 is internally set up with two wire columns 1363, a
crimping board 1364, two springs 1365 and a conductive plate 1366. The
wire columns 1363 respectively connect to the terminals 1362. One end of
the springs 1365 connects to the wire columns 1363 via the crimping board
1364 and the other end of the springs 1365 connects to the rope fixing ring
131 via the conductive plate 1366.

[0077] In the example of Figure 10, the automatic power-on module
136 may stretches the springs 1365 by the difference between the buoyancy
of the buoy 13 in water and the rope pulling force to the rope ring 131,
thereby disconnecting the circuit between the two terminals 1362 and
cutting off the power supply. When the rope is released and the buoy 13
floats to water surface, the rope pulling force is configured to be less than
the force from the springs 1365, for example, by properly selecting the
physical characteristics of the springs 1365, such as the spring constant. At
this time, the two springs 1365 retract and the conductive plate 1366
touches the two terminals 1362, thereby connecting the circuit between the
two terminals 1362.
[0078] Optionally, for convenient use, as depicted in Figure 9, the
buoy
13 may also internally comprise a LED flashing alarm module 139 and so on.
Certainly, the LED flashing alarm module 139 is only a specific example. In
use, other flashing objects may also be used to meet the requirements,
which is not described herein.
[0079] Figure 11 illustrates another exemplary buoy system 3, which
may include a buoy apparatus 1 and a control signal generating device 2.
The control signal generating device 2 may be placed on the boat and may
be configured to communicate with the communication device 14, such as a
Sonar or laser communication device, of the buoy apparatus 1. The buoy
apparatus 1 is underwater connecting to underwater objects.
[0080] As illustrated in the example of Figure 12, the control signal
generating device 2 may include a second communication device 21, and a
control device 22 connecting to the second communication device 21. The
second communication device 21 may be a Sonar or laser communications
device.
[0081] As shown in the example of Figure 13A, the control device 22
may include a second communication interface module 221, a third
microprocessor module 222 and a control signal generating module 223. The
second communication interface module 221 has one end connecting to the
second communication device 21 and the other end connecting to the third
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 19 -
microprocessor module 222. The control signal generating module 223
connects to the third microprocessor module 222.
[0082] Figure 13B illustrates an exemplary communication process
between the control device 22 and the spool control device 11. The controller
device 22 may be on the boat, and the spool control device 11 may be in the
water with the buoy apparatus 1. The user may instruct from the control
device 22, for example by pressing a control button of the control device 22,
the buoy apparatus 1 to release the buoy 13. In response, the third
microprocessor module 222 may send instructions to the second
communication circuit 226, for example to encode and modulate the
instructions, the second communication interface module 221 may prepare
the signal to appropriate form for the transmitter of the second
communication device 21 to transmit the signals carrying the instructions. .
The receiver of the first communication device 14 receives the signals, and
transmitted of the signals to the first communication interface module 113
prepare the signals for demodulation and decoding in the first
communication circuit 115, and the first microprocessor module 111 receive
the instructions from the fist communication circuit 115 for triggering
decoupling of the retractable head 126, as described above.
[0083] The buoy apparatus 1 may be the buoy apparatus 1 as depicted
in Figure 5.
[0084] The second communication device 21 may be any electrical
communications device, such as a Bluetooth device, an infrared device and
so on. Further, similar to the first communication device 14, the second
communication device 21 described may be a transducer with low power
consumption and anti-interference capabilities, for example, Sonar
commination device. When the second communication device 21 is a
transducer, the second communication interface module 221 is specifically a
transducer interface module.
[0085] Figure 12 is only a specific example of control signal generating
device 2. The control signal generating device 2 may have different
configurations from the example as illustrated in Figure 12. For example, the
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 20 -
control signal generating device 2 may be any electrical device that is
capable to transmit control signals, such as a wireless transmitter, a person
computer (PC), a mobile terminal, or other communication devices.
[0086] In some examples, the control signal generating device 2 may
controls at least one of the buoy apparatus 1. In an example, the control
signal generating device 2 may control one buoy apparatus 1, namely that
one control signal generating device 2 connects to and controls one buoy
apparatus 1. In another example, one control signal generating device 2 may
connects with and control multiple buoy apparatuses 1.
[0087] Since the control device 22 may include a third microprocessor
module 222, the control device may include a power module 225 as depicted
in Figure 13A. The power module 225 may be any power supply module as
far as it supplies power, such as a battery.
[0088] In the example of Figure 13A, the control device 22 may also
comprise a display module 224 connecting to the third microprocessor
module 222. The display module 224 may be configured to display, by the
third microprocessor module 222, information of the system 3, for example,
the work status of the system 3, position and other information of the buoy
apparatus 1, etc.
[0089] As depicted in Figure 13A, the control device 22 may also
comprise a second communication circuit 226, a LED indication circuit 227
and other modules. The control device 22 actually are not limited to the
modules illustrated in Figure 13. Other modules, such as GPS module, or Wi-
FiTm Module may also be added to the control device 22.
[0090] Optionally, the control signal generating device 2 may also
include a holding structure 23. In order to conveniently deploy the control
signal generating device 2 on an object above the water, such as boats and
so on, as depicted in Figure 12, the control signal generating device 2 may
also comprise a holding structure 23 which is electrically connected with the
second communication device 21.
R&M REF: 54401-3001
CA 3038171 2019-03-27
- 21 -
[0091] The holding structure 23 may be any structure for fixing the
control signal generating device 2 on an object, such as a boat, above water.
Figure 14 illustrates an exemplary holding structure 23, which may include
two sliding rails 231. A device holding station 232 is slidably placed on the
two sliding rails 231. The device holding station 232 is slidable over the
sliding rails 231 , and the second communication device 21 may be placed
on the device holding station 232. The two ends of each sliding rail 231 are
respectively held by a bracket 233. Each bracket 233 is securely connected
to a fixing portion 234. For example, the holding structure 23 allows the
transmission end of a Sonar communication device to be placed under the
water, the device holding station 232 allows to adjust the position of the
transmission end of the Sonar communication device by sliding over the
sliding rails, so that the receiving end of the communication device 14 under
the water may be easily receive the instructions. Therefore, the holding
structure 23 improves the transmission efficiency of the Sonar
communication device. As depicted in Figure 14, in the present
embodiment, to be more stable, each of the fixing portions 234 is consist of
two parts, a hook 2341 and a powerful magnet 2342. The fixing portion 234
may also be in other configurations that allows the holding structure 23 be
secured on the boad. The hook 2341 and powerful magnet 2342 together
allows the holding structure 23 to be secured on the object, such as the
boat, above the water.
[0092] As illustrated in Figure 14, the second communication device
21
may be fixedly connected on the device holding station 232. Users on the
object, for example on the boat, may use the second communication device
21 to wirelessly communicate with the control device 22, for example, to
communicate with the second communication circuit 226 via the second
communication interface module 221. In some examples, users may
communicate control command or instructions to the control device 22 from
the second communication device 21 to the second communication circuit
226. In response, the third microprocessor module 222 may trigger the
extension or retraction of the rope tied to the buoy apparatus 1.
