[0030] S1: Use the mobile application 100 to send the user request content to the server application 300 through the network and communication module 200.

[0034] The user request content data to be transmitted is encrypted using the constructed encryption algorithm to obtain the encrypted user request content data, wherein the program code of the encryption algorithm is:

[0035]

[0036] Verify the validity of the identity information of the server application 300 through a digital certificate;

[0037] If the identity information of the server application 300 is valid, the encrypted user request content data is sent to the server application 300 .

[0038] S2: The server application 300 selects inspection tasks according to the user request content, and evaluates and organizes the execution results of the inspection tasks to realize intelligent inspection of the substation.

[0053] Traditional technical solutions: Existing substation inspections mainly use traditional manual inspections, video surveillance, comprehensive maintenance vehicles, etc. For some companies, this is too costly, difficult to implement and not easy to promote. It is also difficult to eliminate the influence of human factors in the inspection work. In order to verify that this method has higher inspection efficiency and inspection information recognition accuracy than traditional methods, this embodiment will use traditional manual inspections, video surveillance, comprehensive maintenance vehicles and this method for real-time measurement comparison. The experimental results are shown in the following table.
