6. The power supply equipment operation monitoring system according to claim 1,
and the platform area monitoring terminal reports the running data to be analyzed, which is not matched with the stored power supply monitoring mode, to the power supply monitoring server, and the power supply monitoring server re-matches the power supply monitoring mode with the power supply equipment corresponding to the running data or prompts a user to re-configure the power supply monitoring mode according to the type of the running data to be analyzed.
7. The power supply equipment operation monitoring system according to claim 1,
when the station area monitoring terminal cannot acquire data of other station area monitoring terminals and needs to communicate with other station area monitoring terminals to achieve the data analysis function of the power supply equipment in a cooperative mode, the station area monitoring terminal applies for communication with other station area monitoring terminals to the power supply monitoring server and completes the data analysis function of the power supply equipment in a cooperative mode, and the power supply monitoring server is used for uniformly configuring the station area monitoring terminals in a cooperative mode.
8. The power supply equipment operation monitoring system according to claim 1,
the power supply monitoring server receives monitoring data and equipment operation data sent by the station area monitoring terminal; generating a corresponding power supply monitoring mode according to the received monitoring data and the equipment operation data;
in the monitoring mode of the power supply equipment fault, various monitoring data influencing the stable operation of the power supply station are determined, the important level is configured, the important level of the power supply equipment is monitored in a targeted mode, and the power supply monitoring mode is configured.
9. The power supply equipment operation monitoring system according to claim 1,
the power supply monitoring server acquires power supply station area equipment state data from the station area monitoring terminal, the station area monitoring terminal configures the state data to be sent into summary information, and encrypts the summary information and the power supply station area equipment state data through a private key of the station area monitoring terminal to generate a terminal signature;
the method comprises the steps that a station area monitoring terminal sets an abstract of power supply station area equipment state data to be sent according to a preset power supply station area equipment state data abstract configuration mode;
the power supply monitoring server decrypts and verifies the received encrypted power supply area equipment state data, obtains the power supply area equipment state data sent by the area monitoring terminal corresponding to the ID address, and obtains sending time;
when the power supply monitoring server sends a control instruction to the platform area monitoring terminal, encrypting the sent control instruction through a public key;
and the control instruction is obtained after the platform area monitoring terminal decrypts the received control instruction.
