FIG2 is a flow chart of a method for transmitting power usage information according to an embodiment of the present application. As shown in FIG2 , the method includes the following steps:

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

Specifically, in view of the stability of meter data transmission and the reliability of data transmission in high altitude areas, a high altitude electricity consumption information transmission system based on Beidou short message is designed, as shown in Figure 3, the system mainly includes two parts: Beidou electricity consumption data sending end 10 and receiving end 11. The execution subject of the above-mentioned electricity consumption information transmission method can be the receiving end.

In addition, as shown in Figure 3, the system also includes a server 12, a user electricity meter 13, a Beidou satellite 14 and a ground center station 15. The server is communicatively connected to the receiving end, the user electricity meter is communicatively connected to the sending end, the Beidou satellite is communicatively connected to the sending end and the receiving end respectively, the Beidou satellite is used to transmit data, the ground center station is communicatively connected to the Beidou satellite, and the ground center station is used to control the operation of the Beidou satellite.

Step S202, determining whether the data packet is lost according to the relevant information of the data packet, wherein the relevant information is a sequence number and/or an end flag;

Specifically, the receiving end can determine whether the data packet sent by the sending end is lost, which can be determined based on the arrangement of the sequence numbers, or based on whether the end flag is detected, or based on both of these two information.

Step S203, in the case where the above-mentioned data packet is lost, sending a first data response packet to the above-mentioned sending end, so that the above-mentioned sending end resends the lost data; in the case where the above-mentioned data packet is not lost, uploading the above-mentioned data packet to the server.

Specifically, the sending end is used to collect and send meter data (ie, electricity consumption data), and to resend data upon receiving a command. The sending end may be a concentrator, or a transmitter, or other equipment.

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

Through this embodiment, the sending end collects data and then sends it to the receiving end. The receiving end can determine the transmission status of the data, that is, whether there is data loss. If there is data loss, the sending end will resend the data. This can improve the reliability of the transmission message, ensure data integrity, and improve data transmission efficiency.

Specifically, the processing flow of the above transmission system is shown in Figure 4. The sending end compresses the collected data and sends it in packets through Beidou short messages. The receiving end receives the short message information and assembles it into packets, converts the Beidou protocol data into electricity consumption information, and successfully uploads the package to the main station. The transmission system realizes a series of functions such as interconnection between the sending end and the receiving end, remote meter reading and control, etc.

At present, there are still problems in using Beidou short message communication to transmit electricity consumption information: the length of a single Beidou short message communication is limited. For example, the length of a single message on a commonly used Beidou SIM card is 78.5 bytes; the frequency of Beidou short message communication is limited, and the frequency of civil communication is 60s/time; the Beidou communication link has a certain degree of unreliability, and there is no communication receipt.

Specifically, the use of Beidou short messages for electricity consumption information communication in high-altitude areas has problems such as limited message transmission, low transmission efficiency, and unreliability. The solution of the present application can solve the problem of low electricity consumption information transmission efficiency caused by the limited single message length and communication frequency of Beidou cards, while improving the short message transmission efficiency and data reliability.

During the specific implementation process, receiving the data packet sent by the sender can be achieved through the following steps: receiving a first data packet, wherein the first data packet is a data packet when the sender sends data for the first time; receiving a second data packet, wherein the second data packet is a data packet when the sender sends data for the Nth time, and the second data packet includes incremental data, and the incremental data is the difference between the Nth data and the N-1th data, and N≥2.

In this method, the sending end can determine whether it is the first time to send data, and send data to the receiving end according to the determination result. The receiving end then receives the data. If it is the first time to send data, then the sending end sends the complete meter data. If it is the Nth time to send data, then only incremental data needs to be sent. In this way, there is no need to send redundant data, which can further improve the efficiency of data transmission.

Specifically, for example, the meter data sent for the first time is 100, and before the meter data is sent for the second time, the meter data becomes 101, so incremental data is generated, 101-100=1, and only this 1 is sent to the receiving end.

In the specific implementation process, receiving a data packet sent by the sending end can be achieved through the following steps: receiving multiple data packets, wherein the multiple data packets are sent by the sending end, the sending end collects the meter data of multiple user terminals in turn, and when the total length of the multiple meter data is less than the preset length, writes the multiple meter data into the first data packet to be sent, until the total length of the meter data in the first data packet to be sent is greater than or equal to the preset length, suspends writing data into the first data packet to be sent, writes data into the second data packet to be sent, until all the meter data of all the user terminals are collected, and writes the end flag into the last data packet to be sent.

In this scheme, the sending end can determine the length of the data to be sent. If the length of the data is less than the preset length, it is written into the first data packet to be sent and the data is continued to be read. If the length of the data is still less than the preset length, the data is continued to be read and the operation is repeated until the length of the data is greater than or equal to the preset length. Then, writing data to the first data packet to be sent is stopped and data is written to the second data packet to be sent. The judgment rule for the data length is the same as the judgment rule for the first data packet to be sent. If all the data to be transmitted has been read, the end flag is written. In this way, the data can be packetized to avoid slow data transmission due to too much data in one data packet, thereby further improving the efficiency of data transmission.

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

Specifically, the incremental data compression transmission method is used to improve data transmission efficiency, does not rely on hardware encoding, has good versatility and portability, and is flexible by reading the Beidou card information to adapt the message sending length and frequency.

Specifically, the data processing flow at the sending end is shown in FIG5 , and includes the following steps:

Step A1: Power on and initialize, read Beidou SIM card information, determine the SIM card type, and automatically determine the maximum length X of each data transmission according to the SIM card type;

Step A2: Determine whether the serial port has received the smart meter data. If so, perform the following operations:

(1) Determine whether it is the first time to send the meter data. If it is the first time to send, directly transmit the complete meter data and perform data storage backup;

(2) If it is not the first data transmission, the incremental value between the collected data and the data in the data storage record is determined. If it does not exceed the set threshold, only the meter incremental data is sent. If it exceeds the set threshold (the threshold is adjusted according to the surrounding application environment), the complete meter data needs to be transmitted for data storage backup;

(3) Storing the data to be sent into the sending buffer;

Step A3: Determine the length of the data to be sent. If the length is less than X, write it directly into the sending array (data packet to be sent), and continue to read the next unit. If the sum of the data length is still less than X, continue to write into the sending array; repeat this operation until the sum of the data length is greater than X, and stop reading; if all the data to be transmitted has been taken, write the end flag bit and perform data packetization;

Step A4: perform Beidou short message communication protocol encapsulation, and perform satellite communication data sending operation if the following conditions are met. The sending operation is as follows: if the sum of the data length is greater than X, a short message is sent, or When the counter reaches the SIM card sending interval, a short message is sent.

In order to more accurately determine whether a data packet is lost, there are multiple data packets, and the above-mentioned data packets correspond to the above-mentioned sequence numbers one by one. Determining whether the above-mentioned data packet is lost according to the relevant information of the above-mentioned data packet can be achieved through the following steps: when all the first preset conditions are met, determining that the above-mentioned data packet is not lost, wherein the above-mentioned first preset conditions include: multiple above-mentioned sequence numbers are sorted according to a preset sorting method, the first difference between the Mth above-mentioned sequence number and the M-1th above-mentioned sequence number is equal to the second difference between the Mth above-mentioned sequence number and the M+1th above-mentioned sequence number, and the above-mentioned end flag is obtained; when any of the above-mentioned first preset conditions is not met, determining that the above-mentioned data packet is lost.

In this scheme, if the sequence numbers of multiple data packets are arranged in order from large to small or from small to large, or the sequence number differences between multiple data packets are the same, or the end flag is detected, then it can be determined that the received data packet is not lost. If any of the above conditions is not met, it is determined that the received data packet is lost. In this way, it can be determined more accurately whether the data packet is lost.

Specifically, the sequence numbers of general data packets are arranged in the order of 1, 2, 3, 4, 5, 6. If the sequence numbers of the received data packets are 1, 2, 3, 6, then it is determined that data packets 4 and 5 are lost in the middle, and data packets 4 and 5 are resent subsequently. If the sequence numbers of the received data packets are 1, 2, 4, 5, 6, then it is determined that data packet 3 is lost in the middle, and data packet 3 is resent subsequently.

In some embodiments, after determining whether the above-mentioned data packet is lost based on the relevant information of the above-mentioned data packet, the above-mentioned method also includes the following steps: determining whether a second preset condition is met, wherein the above-mentioned second preset condition includes: the time length for which the above-mentioned data packet is not received is greater than or equal to the target time length, and the above-mentioned data packet cannot be parsed normally; if the above-mentioned second preset condition is met, sending a second response data packet to the above-mentioned sending end, so that the above-mentioned sending end resends the data.

In this scheme, if the receiving end has not received the data packet sent by the sending end and the duration has reached the target duration, or the receiving end finds that the data packet is abnormal after parsing the data packet and the parsed file is garbled, then it can be determined that the received data packet is lost, and the sending end is requested to resend the data packet. If the above conditions are not met, it can be determined that the received data packet is not lost. In this way, it can be determined more accurately whether the data packet is lost, and it can be resent when the data packet is lost. This can further improve the reliability of the transmitted message, further ensure data integrity, and further improve data transmission efficiency.

Specifically, the target duration may be 1 hour, 2 hours, or 1 minute, and may be any feasible duration.

In some embodiments, after determining whether the above-mentioned data packet is lost based on the relevant information of the above-mentioned data packet, the above-mentioned method also includes the following steps: determining whether a third preset condition is met, wherein the above-mentioned third preset condition includes: the time length for which the above-mentioned data packet is not received is greater than or equal to the target time length, and the above-mentioned end flag cannot be obtained; if the above-mentioned third preset condition is met, sending a third response data packet to the above-mentioned sending end, so that the above-mentioned sending end resends the last data packet.

In this scheme, if the receiving end has not received the data packet sent by the sending end, and the duration has reached the target duration, or the receiving end cannot detect the end flag, then it can be determined that the received data packet is lost, and the sending end is requested to resend the last data packet. If the above conditions are not met, it can be determined that the received data packet is not lost. In this way, it can be determined more accurately whether the data packet is lost, and it can be resent when the data packet is lost. This can further improve the reliability of the transmitted message, further ensure data integrity, and further improve data transmission efficiency.

Specifically, the receiving end receives the Beidou short message and parses the message content according to the Beidou short message data format. The data processing flow of the receiving end is shown in FIG6 and includes the following steps:

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

Step B2: The end bit is detected and parsed successfully, the data segment is received, and a data response packet with information content of 0 is sent to the sender, indicating that the data packet is completely received without sub-packet loss (data reception is completed and uploaded to the main station, which is the server);

Step B3: If the packet assembly fails and there is a sub-packet loss, a data response packet with the information content being the sequence number of the lost data sub-packet is sent to the sending end, prompting the sending end (i.e., the acquisition terminal) to resend the lost data;

Step B4: If the Beidou short message signal cannot be received within a foreseeable time or the message content cannot be parsed normally, the data packet for the next step of packetization is searched according to the number, and a data response packet with the information content of the lost data sub-packet sequence number is sent to the sender, prompting the sender to resend the lost data;

Step B5: If there is no new short message within a foreseeable time and the end bit cannot be detected, a data response packet with information content of -1 is sent to the sender to prompt the sender that the end bit is lost and the last packet of data is resent.

Specifically, different types of data response packets are used to prompt the sender of data status, guide the sender to resend, and improve the reliability of Beidou short message transmission data.

In some embodiments, in the event that the above-mentioned data packet is lost, after sending a first data response packet to the above-mentioned sending end so that the above-mentioned sending end resends the lost data, the above-mentioned method also includes the following steps: obtaining the number of resending times; when the above-mentioned number of resending times is greater than or equal to the preset number of times, if it is determined that the above-mentioned data packet is still lost, stopping sending the above-mentioned first data response packet to the above-mentioned sending end, executing the next collection task, and reporting the above-mentioned sending end abnormality to the above-mentioned server; when the above-mentioned number of resending times is less than or equal to the preset number of times, if it is determined that the above-mentioned data packet is resent successfully, uploading the resent data and the above-mentioned data packet to the above-mentioned server.

In this scheme, during the data retransmission process, if the retransmission is unsuccessful, the data retransmission request is sent repeatedly to obtain the number of retransmissions. This process can be repeated for up to a preset number of times. If it is still unsuccessful, the current transmission line status information collection task is abandoned, and the next task is continued, and the sending end abnormality is reported. If the retransmission is successful, the complete data is stored and uploaded to the server, so as to avoid falling into a retransmission endless loop.

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

The embodiment of the present application also provides a transmission device for power consumption information. It should be noted that the transmission device for power consumption information in the embodiment of the present application can be used to execute the transmission method for power consumption information provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated.

At present, there are still problems in using Beidou short message communication to transmit electricity consumption information: the length of a single Beidou short message communication is limited. For example, the length of a single message on a commonly used Beidou SIM card is 78.5 bytes; the frequency of Beidou short message communication is limited, and the frequency of civil communication is 60s/time; the Beidou communication link has a certain degree of unreliability, and there is no communication receipt.

Specifically, the use of Beidou short messages for electricity consumption information communication in high-altitude areas has problems such as limited message transmission, low transmission efficiency, and unreliability. The solution of the present application can solve the problem of low electricity consumption information transmission efficiency caused by the limited single message length and communication frequency of Beidou cards, while improving the short message transmission efficiency and data reliability.

During the specific implementation process, the receiving unit includes a first receiving module and a second receiving module, the first receiving module is used to receive a first data packet, wherein the first data packet is a data packet when the sending end sends data for the first time; the second receiving module is used to receive a second data packet, wherein the second data packet is a data packet when the sending end sends data for the Nth time, and the second data packet includes incremental data, and the incremental data is the difference between the Nth data and the N-1th data, and N≥2.

In this method, the sending end can determine whether it is the first time to send data, and send data to the receiving end according to the determination result. The receiving end then receives the data. If it is the first time to send data, then the sending end sends the complete meter data. If it is the Nth time to send data, then only incremental data needs to be sent. In this way, there is no need to send redundant data, which can further improve the efficiency of data transmission.

Specifically, for example, the meter data sent for the first time is 100, and before the meter data is sent for the second time, the meter data becomes 101, so incremental data is generated, 101-100=1, and only this 1 is sent to the receiving end.

During the specific implementation process, the receiving unit includes a third receiving module, which is used to receive the multiple data packets mentioned above, wherein the multiple data packets are sent by the above-mentioned sending end, and the above-mentioned sending end collects the above-mentioned meter data of multiple user terminals in turn. When the total length of the multiple meter data is less than the preset length, the multiple meter data are written into the first data packet to be sent until the total length of the meter data in the first data packet to be sent is greater than or equal to the preset length, and then the writing of data into the first data packet to be sent is suspended, and the data is written into the second data packet to be sent until all the above-mentioned meter data of all the above-mentioned user terminals are collected, and the end flag is written into the last data packet to be sent.

In this scheme, the sending end can determine the length of the data to be sent. If the length of the data is less than the preset length, it is written into the first data packet to be sent and the data is continued to be read. If the length of the data is still less than the preset length, the data is continued to be read and the operation is repeated until the length of the data is greater than or equal to the preset length. Then, writing data to the first data packet to be sent is stopped and data is written to the second data packet to be sent. The judgment rule for the data length is the same as the judgment rule for the first data packet to be sent. If all the data to be transmitted has been read, the end flag is written. In this way, the data can be packetized to avoid slow data transmission due to too much data in one data packet, thereby further improving the efficiency of data transmission.

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

Specifically, the incremental data compression transmission method is used to improve data transmission efficiency, does not rely on hardware encoding, has good versatility and portability, and is flexible by reading the Beidou card information to adapt the message sending length and frequency.

Specifically, the data processing flow at the sending end is shown in FIG5 , and includes the following steps:

Step A1: Power on and initialize, read Beidou SIM card information, determine the SIM card type, and automatically determine the maximum length X of each data transmission according to the SIM card type;

Step A2: Determine whether the serial port has received the smart meter data. If so, perform the following operations:

(1) Determine whether it is the first time to send the meter data. If it is the first time to send, directly transmit the complete meter data and perform data storage backup;

(2) If it is not the first data transmission, the incremental value between the collected data and the data in the data storage record is determined. If it does not exceed the set threshold, only the meter incremental data is sent. If it exceeds the set threshold (the threshold is adjusted according to the surrounding application environment), the complete meter data needs to be transmitted for data storage backup;

(3) Storing the data to be sent into the sending buffer;

Step A3: Determine the length of the data to be sent. If the length is less than X, write it directly into the sending array (data packet to be sent), and continue to read the next unit. If the sum of the data length is still less than X, continue to write into the sending array; repeat this operation until the sum of the data length is greater than X, and stop reading; if all the data to be transmitted has been taken, write the end flag bit and perform data packetization;

Step A4: perform Beidou short message communication protocol encapsulation, and perform satellite communication data sending operation if the following conditions are met. The sending operation is as follows: if the sum of the data length is greater than X, a short message is sent, or When the counter reaches the SIM card sending interval, a short message is sent.

In order to more accurately determine whether a data packet is lost, there are multiple data packets, and the data packets correspond to the sequence numbers one by one. The first determination unit includes a first determination module and a second determination module. The first determination module is used to determine that the above-mentioned data packet is not lost when all first preset conditions are met, wherein the above-mentioned first preset conditions include: multiple sequence numbers are sorted according to a preset sorting method, the first difference between the Mth sequence number and the M-1th sequence number is equal to the second difference between the Mth sequence number and the M+1th sequence number, and the above-mentioned end flag is obtained; the second determination module is used to determine that the above-mentioned data packet is lost when any of the above-mentioned first preset conditions are not met.

In this scheme, if the sequence numbers of multiple data packets are arranged in order from large to small or from small to large, or the sequence number differences between multiple data packets are the same, or the end flag is detected, then it can be determined that the received data packet is not lost. If any of the above conditions is not met, it is determined that the received data packet is lost. In this way, it can be determined more accurately whether the data packet is lost.

Specifically, the sequence numbers of general data packets are arranged in the order of 1, 2, 3, 4, 5, 6. If the sequence numbers of the received data packets are 1, 2, 3, 6, then it is determined that data packets 4 and 5 are lost in the middle, and data packets 4 and 5 are resent subsequently. If the sequence numbers of the received data packets are 1, 2, 4, 5, 6, then it is determined that data packet 3 is lost in the middle, and data packet 3 is resent subsequently.

In some embodiments, the above-mentioned device also includes a second determination unit and a second processing unit, and the second determination unit is used to determine whether a second preset condition is met after determining whether the above-mentioned data packet is lost based on relevant information of the above-mentioned data packet, wherein the above-mentioned second preset condition includes: the time length for which the above-mentioned data packet is not received is greater than or equal to the target time length, and the above-mentioned data packet cannot be parsed normally; the second processing unit is used to send a second response data packet to the above-mentioned sending end when the above-mentioned second preset condition is met, so that the above-mentioned sending end resends the data.

In this scheme, if the receiving end has not received the data packet sent by the sending end and the duration has reached the target duration, or the receiving end finds that the data packet is abnormal after parsing the data packet and the parsed file is garbled, then it can be determined that the received data packet is lost, and the sending end is requested to resend the data packet. If the above conditions are not met, it can be determined that the received data packet is not lost. In this way, it can be determined more accurately whether the data packet is lost, and it can be resent when the data packet is lost. This can further improve the reliability of the transmitted message, further ensure data integrity, and further improve data transmission efficiency.

Specifically, the target duration may be 1 hour, 2 hours, or 1 minute, and may be any feasible duration.

In some embodiments, the above-mentioned device also includes a third determination unit and a third processing unit, and the third determination unit is used to determine whether a third preset condition is met after determining whether the above-mentioned data packet is lost based on the relevant information of the above-mentioned data packet, wherein the above-mentioned third preset condition includes: the time length for not receiving the above-mentioned data packet is greater than or equal to the target time length, and the above-mentioned end flag bit cannot be obtained; the third processing unit is used to send a third response data packet to the above-mentioned sending end when the above-mentioned third preset condition is met, so that the above-mentioned sending end resends the last data packet.

In this scheme, if the receiving end has not received the data packet sent by the sending end, and the duration has reached the target duration, or the receiving end cannot detect the end flag, then it can be determined that the received data packet is lost, and the sending end is requested to resend the last data packet. If the above conditions are not met, it can be determined that the received data packet is not lost. In this way, it can be determined more accurately whether the data packet is lost, and it can be resent when the data packet is lost. This can further improve the reliability of the transmitted message, further ensure data integrity, and further improve data transmission efficiency.

Specifically, the receiving end receives the Beidou short message and parses the message content according to the Beidou short message data format. The data processing flow of the receiving end is shown in Figure 6, including the following steps:

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

Step B2: The end bit is detected and parsed successfully, the data segment is received, and a data response packet with information content of 0 is sent to the sender, indicating that the data packet is completely received without sub-packet loss (data reception is completed and uploaded to the main station, which is the server);

Step B3: If the packet assembly fails and there is a sub-packet loss, a data response packet with the information content being the sequence number of the lost data sub-packet is sent to the sending end, prompting the sending end (i.e., the acquisition terminal) to resend the lost data;

Step B4: If the Beidou short message signal cannot be received within a foreseeable time or the message content cannot be parsed normally, the data packet for the next step of packetization is searched according to the number, and a data response packet with the information content of the lost data sub-packet sequence number is sent to the sender, prompting the sender to resend the lost data;

Step B5: If there is no new short message within a foreseeable time and the end bit cannot be detected, a data response packet with information content of -1 is sent to the sender to prompt the sender that the end bit is lost and the last packet of data is resent.

Specifically, different types of data response packets are used to prompt the sender of data status, guide the sender to resend, and improve the reliability of Beidou short message transmission data.

In some embodiments, the above-mentioned device also includes an acquisition unit, a fourth determination unit and a fourth processing unit. The acquisition unit is used to send a first data response packet to the above-mentioned sending end in the event that the above-mentioned data packet is lost, so that the above-mentioned sending end obtains the number of retransmissions after retransmitting the lost data; the fourth determination unit is used to stop sending the above-mentioned first data response packet to the above-mentioned sending end when the above-mentioned number of retransmissions is greater than or equal to the preset number of times and it is determined that the above-mentioned data packet is still lost, execute the next collection task, and report the above-mentioned sending end abnormality to the above-mentioned server; the fourth processing unit is used to upload the retransmitted data and the above-mentioned data packet to the above-mentioned server when the above-mentioned number of retransmissions is less than or equal to the preset number of times and it is determined that the above-mentioned data packet is successfully retransmitted.

In this scheme, during the data retransmission process, if the retransmission is unsuccessful, the data retransmission request is sent repeatedly to obtain the number of retransmissions. This process can be repeated for up to a preset number of times. If it is still unsuccessful, the current transmission line status information collection task is abandoned, and the next task is continued, and the sending end abnormality is reported. If the retransmission is successful, the complete data is stored and uploaded to the server, so as to avoid falling into a retransmission endless loop.

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