SYSTEM, METHOD AND APPARATUS FOR TRANSMITTING ELECTRICAL
QUANTITY DATA BASED ON BE1DOU SATELLITE COMMUNICATION
Technical Field
The disclosure relates to the field of communications, in particular to a
system, a
method and an apparatus for transmitting electrical quantity data based on
Beidou
satellite communication.
Background
At present, the transmission of electrical quantity data between a power
supply
area and a data acquisition channel of a master station system is usually
implemented by a General Packet Radio Service (GPRS)/Code Division Multiple
Access (CDMA) wireless channel provided by a public network operator, such as
China Mobile, in the related arts. However, the communication ways are
inapplicable
in many farming and pastoral areas which are sparsely populated and have not
been
is completely covered by mobile signals yet. Thus, how to find an effective
communication way between a master station of the system and a power meter
reading concentrator which is located in the power supply areas where no
public
network signal, no telephone network and no internet exist is a technical
problem to
be solved. The power supply areas, which are all mounted outside, have wide
space
nearby and are not blocked by buildings, so that they meet the data
transmission
requirements based on Beidou satellite short messages although they cannot be
covered by cellular public network signals easily.
The Beidou satellite system has a peculiar short message transmission
function.
In civil areas, the sending frequency supported by the Beidou short message
function
is 30 seconds per frame, and the maximal single frame peculiar to the Beidou
short
message can support stable transmission of 100 bytes, while the receiving
time,
frequency and single frame length are not limited. The data interaction
frequency
between the power meter reading concentrator in the power supply areas and the
master station of the system is not high, but the electrical quantity data
transmitted in
1
CA 02921075 2016-02-11
one time is always much more than 100 bytes. Therefore, when a field meter
reading
concentrator needs to upload electrical quantity data of much more than 100
bytes,
the Beidou satellite short message function cannot support reliable data
transmission.
Summary

case of no
7
CA 02921075 2016-02-11
conflict, the embodiments of the application and features therein can be
combined
with each other.
Fig. 1 is a block diagram showing the structure of an apparatus for
transmitting
electrical quantity data based on Beidou satellite communication according to
an
embodiment of the disclosure. As shown in Fig. 1, the apparatus for
transmitting
electrical quantity data based on Beidou satellite communication includes: an
Ethernet interface 10 which is configured to acquire a power information data
message or a power information data reporting command message, a message
conversion processor 20 which is connected with the Ethernet interface 10 and
is

first
Beidou short messages or convert one or more second Beidou short messages into
the power information data reporting command message; and a serial interface
30
which is connected with the message conversion processor 20 and is configured
to
send one or more first Beidou short messages to a Beidou satellite
communication
apparatus or receive one or more second Beidou short messages from the Beidou
satellite communication apparatus.
In the related arts, power information data cannot be directly transmitted
between a field meter reading concentrator and a central master station system
through a Beidou short message. According to the apparatus shown in Fig. 1,
the
Ethernet interface is configured to acquire a power information data message
or a
power information data reporting command message, the message conversion
processor is connected with the Ethernet interface and is configured to
convert the
power information data message into one or more first Beidou short messages or
convert one or more second Beidou short messages into the power information
data
reporting command message, and the serial interface is connected with the
message
conversion processor and is configured to send one or more first Beidou short
messages to a Beidou satellite communication apparatus or receive one or more
second Beidou short messages from the Beidou satellite communication
apparatus,
namely, the mutual conversion between the power information data message and
8
CA 02921075 2016-02-11
one or more first Beidou short messages and the mutual conversion between one
or
more second Beidou short messages and the power information data reporting
command message are implemented through the message conversion processor,
thus achieving direct bidirectional communication between the field meter
reading
concentrator and the central master station system through a Beidou short
message,
so that the problem that power information data cannot be transmitted directly
between a field meter reading concentrator and a central master station system
through a Beidou short message is solved; and the field meter reading
concentrator
can report residential power information data to the central master station
system
automatically to save lots of manpower, material and financial resources.
In an example embodiment, the Beidou satellite communication apparatus is
connected with the apparatus for transmitting electrical quantity data based
on
Beidou satellite communication in the form of a serial interface, so as to
send and
receive a Beidou data message. When needing to be transmitted in the serial
interface, data can be sent to a Beidou satellite through a Beidou satellite
antenna,
and the Beidou data message issued by the Beidou satellite can be received in
real
time at the same time.
In an example embodiment, the message conversion processor 20 is configured
to parse the power information data message, and split the power information
data
message and convert the splitted power information data message into a
plurality of
first Beidou short messages when it is judged that the number of bytes of the
power
information data message is more than a maximal number of single frame bytes
of
each first Beidou short message.
In an example embodiment, the message conversion processor 20 is
responsible for the mutual conversion between the data frame in the Q/GDW
376.1-2009 power user electric energy data acquisition system communication
protocol: master station communication with data acquire terminal and the data
frame
of the Beidou protocol. The message conversion processor 20 receives a power
information data message reported by a centralized meter reading acquisition
9
CA 02921075 2016-02-11
apparatus through the Ethernet interface 10 in real time and judges whether
the
length of the power information data message exceeds the maximal frame length
of
the Beidou short message which is allowed to be sent in one time. Based on the
judgement result that the length of the power information data message exceeds
the
maximal frame length of the Beidou short message which is allowed to be sent
in one
time, the power information data message reported by the centralized meter
reading
acquisition apparatus is unpacked, then each of the unpacked sub data packages
is
repacked into a Beidou short message which is sent out by the Beidou satellite
antenna.
As an example embodiment of the disclosure, the length of the power
information data message reported by the centralized meter reading acquisition
apparatus may exceed the maximal frame length of the Beidou short message
which
is allowed to be sent in one time, so that it is necessary to unpack the power
information data message reported by the centralized meter reading acquisition
apparatus into sub data packages, and repack each of the unpacked sub data
packages into a Beidou short message which is sent out by the Beidou satellite
antenna in sequence. However, in a long running process, such phenomenon as
packet loss or disorder may occur. To avoid the phenomenon above, six bytes
can be
added to each sub data of the power information data message package, wherein
four bytes represent centurial second, one byte represents the total package
number,
and one byte represents the serial number of the packages. The centurial
second of
the four bytes is used for recombining the messages of the same time into a
whole by
a receiving end; and the total package number is used for representing the
specific
total number of sub data packages needed to be recombined together and can
also
be used for judging whether package loss occurs; and with the serial number of
the
packages, the packages can be recombined according to the sequence of the
serial
number so as to avoid disorder. Therefore, it is necessary to combine the
power
information data messages in the format as shown in Table 1, and the final
communication format of the first Beidou short message is as shown in Table 2.

In an example embodiment, the message conversion processor 20 is configured
to parse the power information data message, and directly convert the power
information data message into one first Beidou short message when it is judged
that
the number of bytes of the power information data message is less than or
equal to
the number of maximal single frame bytes of each first Beidou short message.
In an example embodiment, if the length of the power information data message
reported by the centralized meter reading acquisition apparatus does not
exceed the
maximal frame length allowed to be sent in one time, the power information
data
message reported by the centralized meter reading acquisition apparatus does
not
need to be unpacked, instead the power information data message is directly
recombined into a Beidou short message which is sent out by a Beidou satellite
antenna.
In an example embodiment, the message conversion processor 20 is configured
to verify the integrity and accuracy of one second Beidou short message
received,
and directly convert the second Beidou short message into the power
information
11
CA 02921075 2016-02-11
data reporting command message when the integrity and accuracy of the one
second
Beidou short message are verified successfully.
In an example embodiment, the message conversion processor 20 can receive a
Beidou short message from a Beidou satellite in real time and verify the
integrity and
accuracy of the Beidou short message, and if the integrity and accuracy of the
Beidou
short message are verified successfully, the Beidou short message is converted
into
the power information data reporting command message which is sent to the
centralized meter reading acquisition apparatus through the Ethernet interface
10 in
real time.
In an example embodiment, the message conversion processor 20 is configured
to verify the integrity and accuracy of a plurality of second Beidou short
messages
received, and convert and recombine the plurality of second Beidou short
messages
into the power information data reporting command message when the integrity
and
accuracy of the second Beidou short messages are all verified successfully.
In an example embodiment, the length of the power information data reporting
command message sent by a central master system may exceed the maximal frame
length of the Beidou short message allowed to be sent in one time, so that it
is
necessary to split the power information data reporting command message sent
by a
central master system into a plurality of sub data packages and then convert
the sub
data packages into a Beidou short message, which is sent in sequence. However,
in
a long running process, packet loss or disorder may occur. To avoid the
phenomenon
above, six bytes can be added to the power information data message of each
sub
data package, wherein four bytes represent centurial second, one byte
represents
the total package number, and one byte represents the serial number of the
packages.
The centurial second of the four bytes is used for recombining the messages of
the
same time into a whole by a receiving end; the total package number is used
for
representing the specific total number of sub data packages which need to be
recombined together and can also be used for judging whether package loss
occurs;
12
CA 02921075 2016-02-11
and with the serial number of the packages, the packages are recombined
according
to the sequence of the serial number so as to avoid disorder.
It should be noted that the format of the power information data reporting
command message above can refer to the designing way in Table 1, while the
format
of the Beidou short message above can refer to the designing way in Table 2.
In an example embodiment, the Ethernet interface 10 is configured to receive
the
power information data message reported by a centralized meter reading
acquisition
apparatus (i.e., a field meter reading concentrator).
In an example embodiment, the Ethernet interface 10 is configured to receive
the
power information data reporting command message from a central master station
through a Beidou satellite communication apparatus.
In an example embodiment, the Ethernet interface 10 is responsible for
communicating with a centralized meter reading acquisition apparatus in a
residential
field or a electricity information central master station system, so that the
centralized
meter reading acquisition apparatus can be communicated in real time through
the
Ethernet interface 10, accordingly, the power information data message can be
received from the centralized meter reading acquisition apparatus in real
time, and
the power information data reporting command message issued by the power
information central master station system can be sent to the centralized meter
reading acquisition apparatus in real time.
In an example embodiment, as shown in Fig. 2, the apparatus further includes:
an upgrade device 40 which is connected with the message conversion processor
and is configured to upgrade an embedded program in the message conversion
processor in real time.
In an example embodiment, a USB flash disk with an upgrade executable
program can be inserted into the message conversion processor to upgrade the
internal embedded program of the message conversion processor automatically.
The
13
CA 02921075 2016-02-11
message conversion processor reads whether an executable program is available
in
a USB directory through a thread in real time; and if no executable program is
read, it
is indicated that no USB flash disk is inserted or no executable program needs
to be
upgraded in the USB flash disk currently. If an executable program is read, it
is
indicated that a USB flash disk has been inserted, and whether the executable
program in the USB flash disk has the same version as that of the executable
program running now is judged; if they are the same, it is indicated that it
is
unnecessary to upgrade the program and the program running now has been the
latest program; and if they are different, the executable program running now
is
replaced by the executable program of the USB flash disk, and the process is
killed
by software, in order to restart the device. If the USB flash disk is
unplugged after the
equipment is restarted, it is necessary to redetect whether an executable
program
needed to be downloaded exists; if such executable program exists in the USB
flash
disk, whereas its version is same with that of the program running now, no
processing
is needed and it is necessary to continue to monitor whether a new executable
program is found.
In an example embodiment, as shown in Fig. 2, the apparatus further includes:
a
power supply device 50 which is connected with the message conversion
processor
and is configured to supply power to the message conversion processor.
In an example embodiment, only AC of 200V can exist in a residential field,
and
the power supply device 50 is responsible for converting the field AC220V into
DC12V to power the message conversion processor 20.
Fig. 3 is a block diagram showing the structure of a system for transmitting
electrical quantity data based on Beidou satellite communication according to
an
embodiment of the disclosure. As shown in Fig. 3, the system for transmitting
electrical quantity data based on Beidou satellite communication includes: the
apparatus 1 for transmitting electrical quantity data based on Beidou
satellite
communication, a Beidou satellite communication apparatus 2 which is connected
with a serial interface 30 of the apparatus 1 for transmitting electrical
quantity data
14
CA 02921075 2016-02-11
based on Beidou satellite communication and is configured to send a power
information data message converted by the apparatus 1 for transmitting
electrical
quantity data based on Beidou satellite communication to a central master
station
through a Beidou satellite communication server 3 or receive a power
information
data reporting command message from the central master station through the
Beidou
satellite communication server 3, and the Beidou satellite communication
server 3
which is connected with the Beidou satellite communication apparatus 2 and is
configured to inversely convert the power information data message converted
by the
apparatus 1 for transmitting electrical quantity data based on Beidou
satellite
communication into a power information data message and send the power
information data message to the central master station, or convert the power
information data reporting command message sent by the central master station
and
send the power information data reporting command message converted to the
Beidou satellite communication apparatus 2.
Through the system in Fig. 3, the problem that electricity consumption
information cannot be directly transmitted between a field meter reading
concentrator
and a central master station system through a Beidou short message in the
related
arts is solved, so that the field meter reading concentrator can report the
residential
electricity consumption information to the central master station system
automatically,
so as to save lots of manpower, material and financial resources.
In an example embodiment, firstly, the communication link between the
centralized meter reading acquisition apparatus and the apparatus 1 for
transmitting
electrical quantity data based on Beidou satellite communication is connected
through the Ethernet interface 10; and the communication link between the
apparatus
1 for transmitting electrical quantity data based on Beidou satellite
communication
and the Beidou satellite communication apparatus 2 is connected through the
serial
interface 30. Secondly, the communication link between the Beidou satellite
communication apparatus 2 of a user terminal and the Beidou satellite
communication apparatus of a central master station may be connected through a
CA 02921075 2016-02-11
Beidou satellite communication link. Subsequently, the Beidou satellite
communication apparatus of the central master station sends the received data
to the
Beidou satellite communication server 3 through the serial interface, and the
Beidou
satellite communication server 3 inversely converts one or more Beidou short
messages into the power information data message and transmits it to the
central
master station system in a network mode. Therefore, a Beidou data long message
is
transmitted and received precisely and the mutual conversion between the data
frame in the power user electric energy data acquisition system communication
protocol: master station communication with data acquire terminal and the data
frame
in a Beidou short message format is implemented, and the long message is
unpacked and packed according to 698 statute, so that the transparent data
transmission between the central master station and the field centralized
meter
reading acquisition apparatus is finally implemented.
In contrast, when the power information central master station system sends
the
power information data reporting command message to the centralized meter
reading
acquisition apparatus, the message data is transmitted to the Beidou satellite
communication server of the central master station end according to the power
user
electric energy data acquisition system communication protocol: master station
communication with data acquire terminal. The Beidou satellite communication
server converts the original power information acquisition protocol into the
Beidou
communication protocol and forwards the data to the apparatus 1 for
transmitting
electrical quantity data based on Beidou satellite communication through a
Beidou
communication link, and the apparatus 1 for transmitting electrical quantity
data
based on Beidou satellite communication converts the Beidou communication
protocol into the power information acquisition protocol and transmits it to
the
centralized meter reading acquisition apparatus.
Fig. 4 is a flowchart of a method for transmitting electrical quantity data
based on
Beidou satellite communication according to an embodiment of the disclosure.
As
shown in Fig. 4, the method can include the following steps:
16
CA 02921075 2016-02-11
Step 402: A power information data message is received from a centralized
meter reading acquisition apparatus.
Step 404: The power information data message is converted into one or more
first Beidou short messages.
Step 406: The one or more first Beidou short messages are sent to the Beidou
satellite communication server, wherein the one or more first Beidou short
messages
are restored to the power information data message by the Beidou satellite
communication server and then the power information data message is sent to a
central master station by the Beidou satellite communication server.
In the related arts, the peculiar maximal single frame of the Beidou satellite
communication system can support reliable transmission of short messages of
100
bytes, and the length of the power information data message uploaded by the
centralized meter reading acquisition apparatus in power supply areas may be
much
more than 100 bytes but the transmission frequency of the power information
data
message is actually low. Through the method in Fig. 4, the problem that power
information data cannot be directly transmitted between a field meter reading
concentrator and a central master station system through a Beidou short
message in
the related arts can be effectively solved, so that the field meter reading
concentrator
can report the residential power information data to the central master
station system
automatically, so as to save lots of manpower, material and financial
resources.
In an example embodiment, in Step 404, the step that the power information
data
message is converted into one or more first Beidou short messages can include
the
following Steps:
Step 1: The power information data message is parsed, and whether the number
of bytes of the power information data message is more than the maximal number
of
single frame bytes of each first Beidou short message is judged.

CA 02921075 2016-02-11
Step 2: If not, the power information data message is directly converted into
one
first Beidou short message, and the identity information of the centralized
meter
reading acquisition apparatus is added to the first Beidou short message,
wherein the
identity information is used for identifying the centralized meter reading
acquisition
apparatus to which the first Beidou short message belongs by the Beidou
satellite
communication server.
Step 3: If so, the power information data message is split and converted into
a
plurality of first Beidou short messages, and identity information and the
ordinal
information of each first Beidou short message are added to each first Beidou
short
lo message, wherein the ordinal information is used for recombining the
first Beidou
short messages by the Beidou satellite communication server.
In an example embodiment, the centralized meter reading acquisition apparatus
in the power supply areas can automatically receive the power information data
message which is much more than 100 bytes and is transmitted by the
centralized
meter reading acquisition apparatus, so that it is necessary to automatically
split the
power information data message into a plurality of ordered sub data packages
which
are not more than 100 bytes, and the ordered sub data packages are transmitted
to
the Beidou satellite communication server of the master station through the
Beidou
satellite communication apparatus at a frequency of 30 seconds each time. The
Beidou satellite communication server can identify the centralized meter
reading
acquisition apparatus to which the Beidou short message belongs according to
the
Beidou Identifier (ID) card number in the received Beidou short message (i.e.,
the
identity information aforementioned), namely, the Beidou short messages
reported by
different centralized meter reading acquisition apparatus are distinguished.
In
addition, the ordinal information of the Beidou short message (which can
include the
total package number information and the serial number information of the
packages)
can be used for determining how many Beidou short messages need to be
recombined and which order the Beidou short messages are packaged in, so as to
avoid disorder.

In an example embodiment, before Step 402 the power information data
message is received, the method can further include the following steps:
Step 4: One or more second Beidou short messages are received from a central
master station.
Step 5: The one or more second Beidou short messages are converted into the
power information data reporting command message, wherein the power
information
data reporting command message is used for instructing the centralized meter
reading acquisition apparatus to report power information data.
Step 6: The power information data reporting command message is sent to the
centralized meter reading acquisition apparatus.
In an example embodiment, the central master station system needs to transmit
a temporary meter reading command to the centralized meter reading acquisition
apparatus in each power supply area according to electrical quantity data
transmission statute. The data package length of the temporary meter reading
command transmitted by the central master station is usually less than or
equal to
100 bytes, which does not indicate that the data package length of the
temporary
meter reading command transmitted by the central master station is limited
within
100 bytes, and the data package length of the temporary meter reading command
can be adjusted according to the actual condition (namely, the data package
length of
the temporary meter reading command may exceed 100 bytes), therefore, usually,
the temporary meter reading command transmitted by the central master station
does
not need to be unpacked and packed. When being received from the central
master
station by the Beidou satellite communication server, the temporary meter
reading
command can be converted into one or more Beidou short messages according to
the corresponding relationship between the address information of the
centralized
meter reading acquisition apparatus and the Beidou ID card in Table 2, and
then the
one or more Beidou short messages are sent to the apparatus for transmitting
electrical quantity data based on Beidou satellite communication through the
Beidou
19
CA 02921075 2016-02-11
satellite communication apparatus, and the apparatus for transmitting
electrical
quantity data based on Beidou satellite communication restores it into the
temporary
meter reading command through protocol conversion and then forwards the
temporary meter reading command to the centralized meter reading acquisition
apparatus through an Ethernet interface, so as to complete the transmission of
a
command from the central master station to the centralized meter reading
acquisition
apparatus.
In an example embodiment, in Step 5, the step that one second Beidou short
message is converted into the power information data reporting command message
lo can include the following steps:
Step 51: The integrity and accuracy of the second Beidou short message
received are verified.
Step 52: If the integrity and accuracy of the second Beidou are verified
successfully, the second Beidou short message is directly converted into the
power
information data reporting command message.
In an example embodiment, in Step 5, the step that a plurality of second
Beidou
short messages are converted into the power information data reporting command
message can include the following steps:
Step 53: The integrity and accuracy of the second Beidou short messages
received are verified in sequence.
Step 54: If they are all verified successfully, the second Beidou short
messages
are converted and recombined into the power information data reporting command
message.
It can be seen from what described above that the embodiments above
implement the following technical effects (it should be noted that these
