Description

Technical Field

[0001] The present invention relates to the technical field of electric meter communication, and in particular to a method and device for judging the sending time of electric meter data based on time reverse deduction. Background Art

[0002] With the rapid development of science and technology in human society, communication methods have evolved from wired communication to wireless communication, and the transmission medium has evolved from metal to air. Regardless of the transmission method and medium used, the ultimate goal is to send and receive data quickly and accurately to meet the fundamental needs of human society for communication.

[0003] In the field of electric meter communication, the sending time and receiving time of data are both important factors. Both factors are related to the accuracy of the calculation of some variables of the electric meter. For example, when calculating the accumulated electric energy before and after the load event occurs, the electric meter needs to send the data identifier and the current power value to the receiving end when the load event occurs. After the receiving end receives the data identifier, it can start to accumulate the electric energy generated by the load event. However, it is not accurate to use the start time after the data receiving end completes the data reception as the starting time to accumulate electric energy. This is because the data reception time will lag behind the data sending time.

[0004] Therefore, by estimating the data transmission time as the start time of accumulating electric energy, the calculation error of the accumulated electric energy can be reduced to a certain extent. Summary of the invention

[0055] As used herein, the term "plurality" means two or more than two, unless otherwise specified.

[0056] Figure 1 The flowchart of the method for determining the time of sending electric meter data based on time reverse deduction of the present invention is shown as follows: Figure 1 As shown:

[0057] S1: Under known baud rate conditions, obtain the number of data received by the data receiving end and the data receiving time, obtain the accumulated delay during the data receiving process, and calculate the total number of bits of the received data.

[0058] like Figure 2 As shown, in some embodiments of the present application, starting from the reception of the first bit of data, the number of data received by the data receiving end is calculated; data is continuously received until no more data is received within the timeout period Tu, indicating that the reception is completed, and the reception completion time at this time is recorded as the data reception time Ti.

[0059] In some embodiments of the present application, the baud rate of the current communication may be any one of 4800, 9600, 19200, and 115200. The baud rate is agreed upon in advance by both parties of the communication before the communication begins.

[0060] In some of the embodiments of the present application, by formula

[0061] R d=N×(s+d+e+c)

[0062] Calculate the total number of bits of received data; where N is the number of data received by the data receiving end, s represents the number of start bits, d represents the number of data bits, e represents the number of stop bits, and c represents the number of check bits. Optionally, the start bit is 1 bit, the stop bit is 1 bit, the number of data bits is any one of 8, 10, and 12, and the number of check bits is any one of 1, 1.5, and 2. In a specific implementation, the number of start bits, the number of data bits, the number of stop bits, and the number of check bits are agreed upon in advance by both parties before communication begins.

[0063] In some of the embodiments of the present application, by formula

[0064] T m =R d ×T r +T u

[0065] Calculate the cumulative delay in the data receiving process; where T r Represents the data delay time between each bit, T u The timeout period for receiving data is as follows: Specifically, the timeout period is set by the data receiving end program, and the data delay period is set by the data sending end program.

[0066] Please continue to see Figure 1 :

[0067] According to the formula

[0068]

[0069] Calculate the deduced data sending time of the data sending end; where T o is the deduced data sending time of the data sending end, T i is the data receiving time, B is the baud rate of the current communication, R d Represents the total number of bits of received data, T m Indicates the accumulated delay during data reception.

[0070] In some embodiments of the present application, the real data transmission time of the data transmission end is obtained, and the data communication delay of the electric meter is evaluated according to the difference between the real data transmission time and the deduced data transmission time. Specifically, a test process can be added during implementation, and the real data transmission time of the data transmission can be recorded in advance during the test process to measure the deduced time T o and real time T tSpecifically, the smaller the deviation, the more accurate the deduced data sending time is. Furthermore, the error between the actual sending time and the deduced sending time can be controlled within a preset low-latency evaluation range to achieve low-latency sending and receiving data.

[0071] Furthermore, the present application further illustrates the above steps by calculation:

[0072] According to the example, during the communication process, the baud rate B is set to 9600, the number of start bits s is 1, the number of data bits d is 8, the number of stop bits e is 1, and the number of check bits c is 1. During the communication process, the data delay time Tr for each bit is 0.00005 seconds, and the data receiving timeout time Tu is 0.1 seconds. The number of received data bytes is 3000 bytes.

[0073] According to the formula, we can know the received data

[0074] R d =3000×(1+8+1+1)

[0075] =33000(bit)

[0076] According to the formula, the delay time

[0077] T m =33000×0.00005+0.1

[0078] =1.75 (seconds)

[0079] According to the example, the time T at which data reception ends i is 1.85 seconds. According to the formula, the deduced data sending time is

[0080]

[0081] According to the formula, the actual data sending time is 0 seconds, T o and T t The deviation between d for

[0082] T d =0.01-0=0.01(seconds)

[0083] It should be understood that, although the various steps in the flow chart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
