Further, the master station takes an encryption mode corresponding to a self-owned decryption mode as an encryption mode to be distributed, and sends the encryption mode to be distributed to an online monitoring terminal mounted to a preset power transmission line; the preset power transmission line is a power transmission line located in a geographical area corresponding to the management range of the master station.

Further, after receiving the encrypted online monitoring data packet, the master station may decrypt the encrypted online monitoring data packet based on its own decryption mode, and if the decryption is successful, determine that the encryption mode of the online monitoring data packet corresponds to its own decryption mode.
After the main station receives the encrypted online monitoring data packet, when judging whether the encryption mode of the online monitoring data packet corresponds to the own decryption mode, the main station can decrypt the received encrypted online monitoring data packet by using the own decryption mode of the main station, and if the decryption is successful, the two modes correspond to each other, so that the processing efficiency is improved.
Further, the security gateway may send terminal identifiers of the online monitoring terminals mounted on the preset power transmission line to the master station; the preset power transmission line is a power transmission line located in a geographic area corresponding to the management range of the master station;
