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 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.

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.

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 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.

In the related arts, the peculiar maximal single frame of the Beidou satellite communication system can support reliable transmission of short messages of 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:

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 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.
