s100: the RDSS Beidou communication module is in signal connection with the electric power metering terminal;
s101: the RDSS Beidou communication module receives a dialing signal of the electric power metering terminal so as to establish TCP connection with the electric power metering terminal;

s104: and the RDSS Beidou communication module transmits the second data to the Beidou satellite through a Beidou RDSS communication link.
According to the electric power data acquisition and transmission method provided by the embodiment of the invention, the RDSS Beidou communication module is used for processing the first data acquired from the electric power metering terminal, acquiring the second data comprising the electric power data, and transmitting the second data comprising the electric power data to the Beidou satellite through the Beidou RDSS communication link, so that the first data can be processed in the RDSS Beidou communication module and then the second data comprising the electric power data is extracted, the background of the main station can directly transmit the second data or simply process the second data and then transmit the second data to the main station without operations such as decoding and conversion of the data after receiving the second data, thereby reducing the workload and the resource occupancy rate of the main station, reducing the deployment difficulty of the main station and the electric power data acquisition system, and the RDSS Beidou communication module only needs to transmit the second data comprising the electric power data to the main station, thereby communication efficiency and the effective rate of utilization between RDSS big dipper communication module and the main website have been improved, the communication load of main website and RDSS big dipper communication module has been reduced, in addition, through big dipper RDSS communication link transmission information between RDSS big dipper communication module and the main website, because big dipper satellite's signal can cover the remote mountain areas that public networks such as 2G 3G 4G can not cover, thereby the communication coverage of RDSS big dipper communication module has been enlarged.
Preferably, as shown in fig. 2, the following step S105 is further included after step S101: if the dial response fails, the process returns to step S100. Therefore, after the RDSS Beidou communication module dial response fails, the dial signal sent by the electric power metering terminal can be continuously responded until the response is successful.
Preferably, step 104 is specifically: and after the RDSS Beidou communication module compresses the second data, the second data is transmitted to a Beidou satellite through a Beidou RDSS communication link in a fragmentation mode. Specifically, the RDSS Beidou communication module compresses the second data, encapsulates the second data into Beidou short messages, and transmits the Beidou short messages to the Beidou satellite through the Beidou RDSS communication link in a slicing mode.
Preferably, step S101 is specifically: the RDSS Beidou communication module simulates a PPP dialing server side, and PPP dialing response is carried out on a dialing signal sent by the electric power metering terminal so as to establish TCP connection with the electric power metering terminal.
Preferably, step S102 is specifically: after the dialing response is successful, the RDSS Beidou communication module sends confirmation information to the electric power metering terminal so as to establish TCP connection with the electric power metering terminal, and the RDSS Beidou communication module acquires first data transmitted by the electric power metering terminal. Specifically, the power metering terminal initiates a request (SYNCHRONOUS) for establishing connection, the virtual TCP server of the RDSS beidou communication module responds confirmation information of the request for establishing connection to the power metering terminal, and the RDSS beidou communication module is successfully connected with the TCP of the power metering terminal.
Preferably, step S103 further includes the steps of: the RDSS Beidou communication module receives first data transmitted by the electric power metering terminal and replies data confirmation information to the electric power metering terminal after successful receiving. Specifically, the power metering terminal sends a data packet to the RDSS Beidou communication module, and a TCP flag is marked as PSH and ACK (acknowledgement) is required; and the RDSS Beidou communication module is used for virtualizing a TCP server and responding an Acknowledgement (ACK) packet to the electric power metering terminal. From this, RDSS big dipper communication module can keep connected state with the electric power measurement terminal.
Preferably, as shown in fig. 3, step S103 further includes step S1031: the RDSS Beidou communication module analyzes the login packet in the first data by using the configured data analysis unit and replies login confirmation information to the electric power metering terminal after successful receiving. Preferably, the step S103 further includes the step S1032: the RDSS Beidou communication module analyzes the heartbeat packet in the first data by using the configured protocol data analysis unit, and replies heartbeat confirmation information to the electric power metering terminal after successful receiving. Preferably, step S103 further includes step S1033: the RDSS Beidou communication module analyzes the first data and acquires the second data by using the configured data analysis unit, and replies a receiving confirmation message to the electric power metering terminal after the first data is successfully received.
The first data transmitted by the power metering terminal generally includes data such as a power data packet, a registration packet, and a heartbeat packet. Because the response time of a typical power data acquisition and transmission system is on the order of seconds, and when Beidou short messages are utilized, the response time is on the order of 10 seconds, which causes that two communication parties think that the communication overtime is wrong. Particularly, at the time of heartbeat loop, once the first heartbeat message is not responded in response time, the next two heartbeats and login can not be responded, because the interval of Beidou short message communication is 60s, and the response time limit of the heartbeat and login is generally in the order of several seconds, the system can mistakenly think that the connection is interrupted, and the system can not carry out data communication. Therefore, the RDSS Beidou communication module analyzes and processes the login packet, the heartbeat packet and the power data packet in the first data respectively by using the configured data analysis unit, and after the RDSS Beidou communication module analyzes the login packet, the RDSS Beidou communication module simulates or virtualizes a master station and replies login confirmation information to the power metering terminal, so that the login state of the power metering terminal is kept, and login packet data cannot be transmitted to the master station through a Beidou RDSS communication link. After the RDSS Beidou communication module analyzes the heartbeat package, the RDSS Beidou communication module simulates or virtualizes a main station and replies heartbeat confirmation information to the electric power metering terminal, so that the connection state of the electric power metering terminal is kept, and heartbeat package data cannot be transmitted to the main station through the Beidou RDSS communication link. After the RDSS Beidou communication module analyzes the second data and successfully receives the first data, the RDSS Beidou communication module simulates or virtualizes a master station and replies receiving confirmation information to the power metering terminal so as to be connected with the power metering terminal, wherein the second data comprise power data or other data. The RDSS Beidou communication module compresses the analyzed second data, encapsulates or converts the second data into Beidou short messages, and transmits the Beidou short messages to the Beidou satellite through the Beidou RDSS communication link in a slicing mode. Therefore, the RDSS Beidou communication module can transmit more electric power data through the Beidou RDSS communication link, less or no non-electric power related data can be transmitted, the occupation of the non-electric power related data on the Beidou RDSS communication link is reduced, the channel load of the Beidou RDSS communication link is reduced, and the communication transmission efficiency of the RDSS Beidou communication module is improved.
