[0002] In the existing residential electricity consumption information collection mode, the electric energy meter that collects electricity consumption information will send the electricity consumption data to the concentrator under the nearby desktop transformer in a carrier mode. The concentrator sends the data to the electricity consumption information collection master station system deployed in the local power company through optical fiber, microwave or mobile phone network. In Qinghai, Xinjiang, Tibet, Sichuan, Yunnan, Guizhou, Hebei and other regions in my country, there are a large number of pastoral areas and mountainous areas that lack communication means. The collection of residential electricity consumption information in such areas is a difficult problem for local power supply companies. They can only drive dozens or even hundreds of kilometers once a month to read the meters manually. This method is very unfavorable for power automation management. For this reason, the present invention develops a BeiDou-3 short message transmission method for multi-protocol integration of power services to solve the above technical problems. Summary of the invention

[0007] S2, Beidou command machine receives the frozen data and transmits the data to Beidou front-end machine;

[0008] S3, the Beidou front-end performs preliminary analysis, packaging and analysis on the Beidou short message in sequence, and then saves the processed complete frozen data;

[0034] S4. When the electricity consumption information collection system initiates a call for frozen data in the Beidou front-end, the front-end will feed back the corresponding frozen data according to the pre-collection scheduling mechanism to realize the collection of electricity consumption information.

[0035] In this embodiment, the information sending priority of the Beidou power consumption information collection terminal in step S1 follows the following principles (such as Figure 2 shown):

[0037] 2) 101 / 104 protocol data will be returned in the order in which the data is generated.

[0038] In this embodiment, the concentrator or special transformer in step S1 obtains the meter freezing data including daily freezing data and 15-minute freezing data, specifically: before 20:00 every day, within every 15 minutes, without being interrupted by other data, the Beidou electricity consumption information collection terminal first collects and returns the 15-minute freezing data of the designated meter, and after the 15-minute freezing data reporting is completed, it starts to poll and report the daily freezing data of all the downstream meters in sequence. When the remaining time within 15 minutes cannot transmit the daily freezing of all the downstream meters, the remaining daily freezing data of the downstream meters will continue to be reported within the next round of 15 minutes, and so on. After 20:00 every day, the Beidou device will no longer report the daily freezing data, and only transmit the minute freezing data within every 15-minute interval (such as Figure 3 The time required for reporting data in each 15-minute round depends on the communication frequency of the Beidou card and the amount of data transmitted in each packet.

[0039] In this embodiment, in step S1, when the data packet data collected by the Beidou electricity consumption information collection terminal is long, the data is first subpacketized and then encapsulated by the Beidou protocol, and finally periodically subpacketized and sent; and the Beidou front-end in step S3, after receiving the subpacketized data, sequentially assembles and verifies the data to form complete business data, and assembles the data according to the frame header identifier of the subpacketized data.

[0043] In this embodiment, when the data is converted to a protocol, since the State Grid's electricity consumption information collection is carried out in accordance with the power user electricity consumption information collection system communication protocol (abbreviated as: State Grid communication protocol), the protocol data packet needs to be converted into a Beidou protocol data packet and sent to the master station via the Beidou communication link. At the master station, the Beidou protocol data packet is restored to a State Grid communication protocol data packet. The above protocol conversion is performed at both ends of the Beidou communication link, does not affect the original communication mode, realizes data transparent transmission, and the State Grid communication protocol data packet frame format is as follows: Figure 5 As shown, after conversion into the Beidou protocol, the State Grid communication protocol data packet will be encapsulated in the frame format of the Beidou protocol as a Beidou protocol data packet.
