MULTI-PROCESSOR BURGLAR-PROOF
APPARATUS
FIELD OF THE INVENTION
The present invention relates to a burglar-proof apparatus
and particularly to a multi-processor burglar-proof apparatus
that has a plurality of detection processors each is separately
linked to a radio alarm and a radio help system by radio
signals.
BACKGROUND OF THE INVENTION
Conventional burglar-proof systems such as the one shown
in FIG. 1 generally have a plurality of sensors 2 installed on
locations where intruders might invade and a receiving
processor 1 located at a selected position. Such a
burglar-proof system must have the receiving processor 1
installing on a fixed location. As installation of the receiving
processor 1 must take into account of the possibility of being
sabotaged, it must be located in a secret or concealed area.
Because once the receiving processor 1 is damaged, all the
sensors 2 are not effective and become useless. Since the
receiving processor 1 has to be installed on a concealed
location, user operation and maintenance becomes
inconvenient.
Moreover, the size of the receiving processor 1 and sensors
2 is quite bulky. Except on some selected locations, they are
not portable. In the event of natural disasters occur (such as
1

earth quake, power failure, flood, avalanche, fire, or the like), they also
do not provide help or contingent functions.
SUMMARY OF THE INVENTION
Therefore the object of the invention is to provide a multi-processor
burglar-proof apparatus that has a plurality of detection processors. At
least one detection processor is located in each detection area. Each
detection processor is separately linked to a radio alarm and a radio help
system by radio signals.
Another object of the invention is to provide a help function in the
event of natural disasters occur. As each detection area has a detection
processor, users can easily access the detection processor and use the
functional input interface to ask for external assistance.
In one particular embodiment there is provided a multi-processor
burglar-proof apparatus comprising a plurality of detection processors
with at least one detection processor located in each detection area and
each detection processor is separately linked to a radio alarm and a radio
help system by radio signals, the detection processor having a control
circuit which includes a first control unit and a second control unit, the
second control unit being connected to the first control unit;
wherein the first control unit includes:

127.
In addition, referring to FIGS. 3 and 4A through 4K, the
detection processor 10 includes a control circuit 20 which has
a first control unit 21 and a second control unit 22. The first
control unit 21 includes:
an infrared light sensor unit 201 for receiving signals from
the infrared light sensor 160 and emitting detection signals to
a microprocessor unit 204 which in turn issues signals to a
radio emission unit 206, a memory unit 203 for storing signal
status of other units such as password signals of an operation
unit 202 or detected signals of the infrared light sensor unit
201, the microprocessor unit 204 which processes and controls
the signals of other units and compares the passwords entered
from the operation unit 202 with the password signals pre-
stored in the memory unit 203 for decoding, the radio
emission unit -206 which transmits the signals (such as alarm
status and data) processed by the microprocessor unit 204 to a
radio alarm 30 and a radio help system 40 by radio signals,
and a power supply backup unit 210 which provides backup
power supply for the control circuit 20 in the event of power
failure. A charger unit 213 is included to charge electric
power.
The second control unit includes: a photosensitive
4
CA 02431968 2003-06-11
detection unit 200 for receiving signals detected by the
photosensitive sensor 161 and transmitting the signals to the
microprocessor unit 204 which in turn issues signals to a
lighting unit 208, the operation unit 202 for entering input
password signals into the microprocessor unit 204 to release
the alarm condition of the detection processor 10, a display
unit 207 to receive operation and status signals delivered by
the microprocessor unit 204 and display the signals on the
display interface 13, the lighting unit 208 receiving the signals
from the microprocessor unit 204 to determine whether to turn
light sources ON or OFF and adjust light brightness, an alarm
unit 209 which receives signals from the microprocessor unit
204 and transmit signals to an alarm indication light 14, a
speaker unit 211 which receives signals from the
microprocessor unit 204 and generates alarm sound to alert
operators, and a SOS help unit 212 which receives signals
from the SOS key 127 and delivers signals to the
microprocessor unit 204 so that the microprocessor unit 204
may generate Morse codes to the lighting unit 208, speaker
unit 211 and radio emission unit 206.
Referring to FIGS. 2, 3 and 5, by means of the construction
set forth above, the multi-processor burglar-proof apparatus of the
invention can achieve the following effects:
1. Each detection area T has at least one detection processor 10,
and a plurality of the detection processors 10 form the
5
CA 02431968 2003-06-11
multi-processor burglar-proof apparatus. And each detection
processor 10 is separately linked to the radio alarm 30 and
the radio help system 40 through a radio transmission. Thus
when intruders invade and are detected by the infrared light
sensor 160, the microprocessor unit 204 of the control circuit
20 transmits signals to the radio, alarm 30 and the radio help
system 40 by radio signals to achieve burglar prevention
object. It is to be noted that even if the intruder discovers and
disables the detection processor 10 in one detection area T, the
detection processors 10 in the rest detection areas T are still
functionable and can continuously process detection.
Moreover, when the detection processor 10 is disabled, the
detection signals have already been sent to the radio alarm 30
and the radio help system 40. This is a significant difference
from the conventional burglar-proof systems. As the
conventional burglar-proof systems generally have a plurality
of sensors 2 located in each detection area, and a single
processor 1 receives the detected signals from the sensors 2
and activates the alarm and help system 3 and 4, once the
processor 1 is disabled, all the sensors 2 deployed in the house
are useless.
2. The detection processor 10 of the invention has a backup
power supply unit 210. Power failure is not a concern.
Moreover, users can easily reset and release the password of
alarm status through the numerical input interface 11 of the
6
CA 02431968 2003-06-11
detection processor 10. Thus the detection processor 10 may
be installed wherever users want without the need of
concealing. Once the detection processor 10 detects intruders,
a preset audio alarm will be generated, and light will be
projected to scare off the intruders and achieve burglar
prevention effect.
3. Aside from generating alarm or help signals when detecting
intruders, the SOS key 127 on the detection processor 10 may
also be used to generate Morse code signals in the event of
earth quake or fire to increase helping chance. Thus the
invention has a greater added value and is less likely be idled.
4. The invention can also provide other functions such as
illumination besides burglar prevention. The photosensitive
sensor unit 200 in the control circuit 20 of the detection
processor 10 can automatically detect the brightness of light
sources and transmit suitable signals to the microprocessor
unit 204 which issues signals to the lighting unit 208 to
control ON or OFF of the indication light 15. Thus in the
event of users return home at night or power failure occurs,
the detection processor 10 can automatically generates light to
indicate passages or escape routes. In the event of power
failure, the flashlight key 122, power failure lighting key
124, and automatic lightening key 125 of the detection
processor 10 can provide lighting function.
