Fig. 2 is a flow chart of a method for transmitting electricity information according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:

step S201, receiving a data packet sent by a sending end, wherein the data packet is generated by the sending end according to the number of times of sending the ammeter data and updated ammeter data, and the data format of the data packet is Beidou short message;

Specifically, for the stability of data transmission of the ammeter and the reliability of data transmission of the high-altitude area, a transmission system of high-altitude electricity consumption information based on Beidou short messages is designed, as shown in fig. 3, and the system mainly comprises two parts: a transmitting end 10 and a receiving end 11 of the Beidou electricity utilization data. The execution subject of the above-described transmission method of electricity information may be a receiving end.

In addition, as shown in fig. 3, the system further comprises a server 12, a user electric meter 13, a Beidou satellite 14 and a ground central station 15, wherein the server is in communication connection with a receiving end, the user electric meter is in communication connection with a transmitting end, the Beidou satellite is in communication connection with the transmitting end and the receiving end respectively, the Beidou satellite is used for transmitting data, the ground central station is in communication connection with the Beidou satellite, and the ground central station is used for controlling the Beidou satellite to operate.

Step S202, determining whether the data packet is lost or not according to the related information of the data packet, wherein the related information is a sequence number and/or an end flag bit;

Specifically, the receiving end may determine whether the data packet sent by the sending end is lost, may be determined according to the sequence number arrangement, may be determined according to whether the end flag bit is detected, or may be determined according to both the two information together.

Step S203, when the data packet is lost, a first data response packet is sent to the sending end, so that the sending end supplements the lost data, and when the data packet is not lost, the data packet is uploaded to a server.

Specifically, the transmitting end is used for collecting and transmitting ammeter data (i.e. electricity consumption data) and receiving command reissue data, and the transmitting end can be a concentrator, a transmitter or other devices.

Specifically, the receiving end is configured to receive data sent by the sending end, and send a command for repairing the sent data to the sending end.

Through the embodiment, the sending end collects data and sends the data to the receiving end, the receiving end can judge the transmission state of the data, namely whether the data is lost, if the data is lost, the sending end supplements the data, so that the reliability of a transmission message can be improved, the integrity of the data is ensured, and the data transmission efficiency is improved.

Specifically, as shown in fig. 4, the processing flow of the transmission system is that the transmitting end compresses the collected data, the collected data is sent in packets through the beidou short message, the receiving end receives the short message information and packages the short message information, the beidou protocol data is converted into electricity information, and the package is successfully uploaded to the host station. A series of functions such as interconnection and intercommunication of a transmitting end and a receiving end, remote meter reading and control are realized through a transmission system.

At present, the power consumption information transmission by adopting Beidou short message communication has the following problems: the length of a single message of Beidou short message communication is limited, for example, the length of a single message of a commonly used Beidou SIM card is 78.5Byte; the communication frequency of the Beidou short message is limited, and the civil communication frequency is 60 s/time; the Beidou communication link has certain unreliability and no communication receipt.

Specifically, aiming at the problems of limited message transmission, low transmission efficiency, unreliable and the like in the power consumption information communication by adopting the Beidou short message in the high-altitude area, the scheme of the application can solve the problem of low power consumption information transmission efficiency caused by limited single message length and communication frequency of the Beidou card, and simultaneously improve the short message transmission efficiency and the data reliability.

In the specific implementation process, the receiving of the data packet sent by the sending end can be realized by the following steps: receiving a first data packet, wherein the first data packet is a data packet when the transmitting end transmits data for the first time; and receiving a second data packet, wherein the second data packet is a data packet when the transmitting end transmits data for the nth time, the second data packet comprises incremental data, the incremental data is the difference value between the data of the nth time and the data of the (N-1) th time, and N is more than or equal to 2.

In the method, the transmitting end can determine whether to transmit data for the first time, the data is transmitted to the receiving end according to the determined result, the receiving end receives the data again, if the data is transmitted for the first time, the transmitting end transmits complete ammeter data, if the data is transmitted for the nth time, only incremental data is required to be transmitted, redundant data is not required to be transmitted, and the data transmission efficiency can be further improved.

Specifically, for example, when the first transmission of the meter data is 100 and the meter data becomes 101 before the second transmission of the meter data, incremental data is generated, 101-100=1, and only 1 is transmitted to the receiving end.

In the specific implementation process, the receiving of the data packet sent by the sending end can be realized by the following steps: and receiving a plurality of data packets, wherein the data packets are transmitted by the transmitting end, the transmitting end sequentially collects the ammeter data of a plurality of user ends, under the condition that the sum of the lengths of the ammeter data is smaller than a preset length, the ammeter data are written into a first data packet to be transmitted until the sum of the lengths of the ammeter data in the first data packet to be transmitted is larger than or equal to the preset length, writing data into the first data packet to be transmitted is suspended, writing data into a second data packet to be transmitted, and writing an ending mark bit into the last data packet to be transmitted until all the ammeter data of all the user ends are completely collected.

In the scheme, the transmitting end can determine the length of data to be transmitted, the length of the data is smaller than the preset length, the data is written into a first data packet to be transmitted, the data is continuously read, if the length of the data is still smaller than the preset length, the data is continuously read, the operation is repeated until the length of the data is larger than or equal to the preset length, the data is stopped being written into the first data packet to be transmitted, the data is written into a second data packet to be transmitted, the judging rule of the data length is consistent with the judging rule of the first data packet to be transmitted, if the data to be transmitted is completely read, the end zone bit is written, the data is packetized, and the data transmission is slow due to too much data in one data packet, so that the data transmission efficiency is further improved.

Specifically, the preset length may be 78.5 bytes, or 128 bytes, or other lengths.

Specifically, the incremental data compression transmission method is adopted to improve the data transmission efficiency, hardware coding is not relied on, the universality and portability are good, the self-adaption of the message transmission length and the message transmission frequency is carried out by reading the adopted Beidou card information, and the flexibility is achieved.

Specifically, as shown in fig. 5, the data processing flow of the transmitting end includes the following steps:

Step A1: powering up and initializing, reading Beidou SIM card information, judging the type of the SIM card, and automatically judging the maximum length X of data transmitted each time according to the type of the SIM card;

step A2: judging whether the serial port receives the data of the intelligent electric meter, and if so, performing the following operations:

(1) Judging whether the electric meter data is sent for the first time, if so, directly transmitting the complete electric meter data, and carrying out data storage backup;

(2) If the data is not transmitted for the first time, the increment value between the acquired data and the data in the data storage record is judged, if the increment value does not exceed a set threshold value, only the ammeter increment data is transmitted, and if the increment value exceeds the set threshold value (the threshold value is adjusted according to the surrounding application environment), the complete ammeter data is required to be transmitted for data storage backup;

(3) Storing data to be transmitted into a transmission buffer area;

Step A3: judging the length of data to be transmitted, if the length is less than X, directly writing the data into a transmission array (data packet to be transmitted), continuously reading the next unit, and if the sum of the data length is still less than X, continuously writing the data into the transmission array; repeating the operation until the sum of the data length is greater than X, and stopping reading; if the data to be transmitted are all fetched, writing an ending zone bit, and carrying out data subpackaging;

step A4: and (3) packaging the Beidou short message communication protocol, and performing satellite communication data transmission operation under the following conditions: the sum of the data length is greater than X, short message transmission is carried out, or And the counter reaches the SIM card sending interval to send the short message.

In order to accurately determine whether a data packet is lost, the number of the data packets is plural, the data packets correspond to the sequence numbers one by one, and whether the data packet is lost is determined according to the related information of the data packets, the method can be realized by the following steps: and under the condition that all first preset conditions are met, determining that no data packet is lost, wherein the first preset conditions comprise: the sequence numbers are ordered according to a preset ordering mode, the first difference value between the Mth sequence number and the M-1 th sequence number is equal to the second difference value between the Mth sequence number and the M+1th sequence number, and the end zone bit is obtained; and determining that the data packet is lost when any one of the first preset conditions is not met.

In this scheme, if the sequence numbers of the plurality of data packets are arranged in the order from large to small or from small to large, or the sequence number differences among the plurality of data packets are the same, or the end flag bit is detected, it can be determined that the received data packet is not lost, and if any condition is not satisfied, it is determined that the received data packet is lost, so that it can be determined more accurately whether the data packet is lost.

Specifically, the sequence numbers of the general data packets are arranged in the order of 1,2, 3, 4, 5 and 6, if the sequence number of the received data packet is 1,2, 3 and 6, it is determined that two data packets of 4 and 5 are lost in the middle, two data packets of 4 and 5 are sequentially reissued, and if the sequence number of the received data packet is 1,2, 4, 5 and 6, it is determined that 3 data packets are lost in the middle, and 3 data packets are sequentially reissued.

In some embodiments, after determining whether the data packet is lost according to the related information of the data packet, the method further includes the steps of: determining whether a second preset condition is met, wherein the second preset condition comprises: the duration of the data packet which is not received is longer than or equal to the target duration, and the data packet cannot be normally analyzed; and sending a second response data packet to the sending end under the condition that the second preset condition is met, so that the sending end resends the data.

In the scheme, if the receiving end can not always receive the data packet sent by the sending end and the time length reaches the target time length, or the receiving end finds that the data packet is abnormal after analyzing the data packet, the analyzed file is a messy code, then the receiving end can be determined to have a loss and request the sending end to resend the data packet, if the conditions are not met, then the receiving end can be determined to have no loss, thus the receiving end can accurately determine whether the data packet is lost or not, and can carry out reissue when the data packet is lost, thus the reliability of the transmission message can be further improved, the data integrity is further ensured, and the data transmission efficiency is further improved.

Specifically, the target duration may be 1h, 2h, or 1min, and may be any feasible duration.

In some embodiments, after determining whether the data packet is lost according to the related information of the data packet, the method further includes the steps of: determining whether a third preset condition is met, wherein the third preset condition comprises: the duration of the data packet which is not received is greater than or equal to the target duration, and the ending zone bit is not acquired; and sending a third response data packet to the sending end under the condition that the third preset condition is met, so that the sending end reissues the last data packet.

In the scheme, if the receiving end can not always receive the data packet sent by the sending end and the time length reaches the target time length, or the receiving end can not detect the end flag bit, the receiving end can determine that the received data packet is lost, request the sending end to resend the last data packet, and if the conditions are not met, the receiving end can determine that the received data packet is not lost, so that whether the data packet is lost can be accurately determined, and the data packet can be reissued when being lost, thereby further improving the reliability of a transmission message, further ensuring the integrity of data and further improving the data transmission efficiency.

Specifically, the receiving end receives the Beidou short message, analyzes the message content according to the Beidou short message data format, and the data processing flow of the receiving end is shown in fig. 6, and comprises the following steps:

Step B1: the receiving end receives the Beidou short message signal, analyzes the message content and assembles the message content according to the data sub-packet sequence number identified by the packet header;

step B2: detecting an end bit, analyzing successfully, finishing the data receiving, and sending a data response packet with information content of 0 to a sending end, wherein the data response packet indicates that the data packet is completely received without sub-packet loss (finishing data receiving, uploading a master station, namely a server);

Step B3: if the group of the packets fails, the sub-packets are lost, a data response packet with the information content of the sequence number of the lost data sub-packet is sent to a sending terminal, and the sending terminal (namely the acquisition terminal) is prompted to perform lost data reissue;

Step B4: if the Beidou short message signal cannot be received or the message content cannot be normally analyzed within the foreseeable time, searching the data packet of the next packet according to the number, sending a data response packet with the information content of the sequence number of the lost data sub-packet to a sending end, and prompting the sending end to carry out lost data reissue;

Step B5: if no new short message is available in the foreseeable time and the ending bit is not detected, a data response packet with the information content of-1 is sent to the sending end, the sending end is prompted to lose the ending bit, and the last packet of data is sent in a reissue mode.

Specifically, the data response packets of different types are adopted to prompt the data state of the transmitting end, the transmitting end is guided to retransmit, and the reliability of the Beidou short message transmission data is improved.

In some embodiments, in the case that the data packet is lost, the method further includes the following steps after sending a first data response packet to the sending end, so that the sending end supplements the lost data: acquiring the number of reissue times; when the number of the reissue times is greater than or equal to the preset number of times, and the data packet is still lost, stopping sending the first data response packet to the sending end, executing the next collection task, and reporting the abnormity of the sending end to the server; and uploading the reissued data and the data packet to the server under the condition that the reissued times are less than or equal to the preset times and the successful reissuing of the data packet is determined.

In the scheme, in the data reissue process, if reissue is unsuccessful, repeatedly sending a data reissue request, obtaining reissue times, repeatedly presetting times in the process, if the reissue is unsuccessful, discarding the current transmission line information acquisition task, continuously executing the next task, reporting the abnormity of a sending end, and if the reissue is successful, storing and uploading complete data to a server, so that the reissue death cycle can be avoided.

Specifically, the preset number of times is 3 times, or 5 times, or other times.
