[0060] S3, define the remote signaling variable position sending frame as the first needle remote control command frame, execute step S1;

[0061] In a specific implementation, when a user inputs a detection instruction of a remote device, a first frame message data is determined, and according to a remote control object identifier in the frame message, a corresponding remote control feedback frame is found, if the remote control feedback result is failure, it indicates that the remote control execution fails, the next frame remote control command is continuously read for analysis until the analysis ends, if the remote control feedback succeeds, the remote signaling variable position sending frame closest to the time after the time of the frame message is found according to the time of the frame message and the remote control object identifier, and the time difference between the remote control command frame and the remote signaling variable position sending frame, that is, the remote control response time, is calculated.

[0063] S5, determine whether the target remote device needs to be analyzed for defects according to the remote control response time and the average response time.

[0064] In an optional embodiment, the step S5 includes:

[0065] S51, determine the number of long remote control response times with a time length greater than a preset time length in all the remote control response times, and the number of response times greater than the average response time in all the remote control response times;

[0066] S52, determine whether the target remote device needs to be analyzed for defects based on the average limit time, the number of response times and the number of long remote control response times.

[0067] According to the embodiment of the application, in response to the accepted first frame remote control command frame, it is judged whether the first frame remote control command frame exists a remote signaling variable position sending frame, if not, step S4 is executed, in step S2, the time difference between the first frame remote control command frame and the remote signaling variable position sending frame is calculated, the remote control response time is obtained, and the total remote control command number is adjusted, in step S3, the remote signaling variable position sending frame is defined as the first needle remote control command frame, and step S1 is executed, in step S4, the average response time is determined based on all the remote control response times and the total remote control command number, and in step S5, whether the target remote device needs to be analyzed for defects is determined according to the remote control response time and the average response time. The message data sent by the remote machine of the substation is analyzed, the indexes related to the response time of the message data are counted, and then the operation state of the remote device is comprehensively evaluated, so that the safety and stability of the substation are ensured.

[0068] Please refer to Figure 2 , the step flow chart of the second embodiment of the method for determining the maintenance of the remote device of the application, specifically comprising:

[0069] Step S201, in response to the accepted first frame remote control command frame, judging whether the first frame remote control command frame exists a remote signaling position sending frame; if not, executing step S204;

[0070] Step S202, calculating the time difference between the first frame remote control command frame and the remote signaling position sending frame, obtaining the remote control response time and adjusting the total remote control command number;

[0071] Step S203, defining the remote signaling position sending frame as the first remote control command frame, executing step S201;

[0072] Step S204, determining the average response time based on all the remote control response times and the total remote control command number;

[0073] In the embodiment of the application, the remote control response time is counted in the accumulated remote control response time, and the average response time is obtained by dividing the accumulated remote control response time by the total remote control command number (i.e. the number of remote control command frames that have been read so far), and stored in the database.

[0074] Step S205, determining the number of long remote control response times whose time length is greater than a preset time length among all the remote control response times, and the number of response times greater than the average response time among all the remote control response times;

[0075] Step S206, taking the ratio of the number of long remote control response times to the number of all remote control response times as the long response proportion;

[0076] In the embodiment of the application, if the remote control response time is greater than 3 seconds, the number of times that the response time of the station in the database is greater than 3 seconds is increased by 1, i.e. the number of response times greater than the average response time in the remote control response time is increased by 1, and then the proportion of response times greater than 3 seconds is obtained by dividing the number of times that the response time is greater than 3 seconds by the total remote control command number and stored in the database.

[0077] Step S207, determining the proportion of response times greater than the average response time by taking the ratio of the number of response times to all the remote control response times;

[0078] In the embodiment of the application, if the remote control response time is greater than the average response time, the number of times that the response time is greater than the average is increased by 1 and stored in the database, and then the proportion of response times greater than the average is obtained by dividing the number of times that the response time is greater than the average response time by the total remote control command number and stored in the database.

[0079] Step S208: Determine whether the target telemetry device needs to undergo defect analysis based on the response time ratio and the long response ratio.

[0082] S2082, determine whether the long response ratio is greater than the preset long response ratio; if so, determine whether the target telemetry device needs to undergo defect analysis.

[0083] S2083, determine that there is no need for maintenance of the target remote control device.

[0084] In this embodiment of the invention, if the response time ratio is greater than the preset response ratio, or the long response ratio is greater than the preset long response ratio, it can be considered that there is a safety hazard in the station's remote control device, measurement and control device, or switch body. Timely inspection should be carried out to avoid the dispatcher or AVC system misjudging and making incorrect operations due to untimely feedback of remote control results, which could lead to a power grid safety accident.

[0085] In addition, if the remote control response time is greater than the maximum remote control response time recorded in the database, it will be replaced with the new maximum remote control response time and stored in the database; if the remote control response time is less than the minimum remote control response time recorded in the database, it will be replaced with the new minimum remote control response time and stored in the database.

[0086] Through the above steps, we can obtain:

[0087] t max =max{t c1 ,t c2 ,......t ck}

[0088] t min =min{t c1 ,t c2 ,......t ck}

[0089]

[0090] n t＞3 =n(T'), where T'={t'|t'∈T,t'>3}

[0091]

[0092] n t＞a= n(T"), wherein T" = {t" | t" e T, t" > t a}

[0093]
