[0006] The SCD matching module extracts SCD configuration file information and security requirement information, sets security monitoring rules according to the SCD configuration file information and the security requirement information, and obtains a data security monitoring rule configuration file, a security monitoring strategy configuration file and a switch forwarding configuration file.

[0007] The multi-level security monitoring module performs security monitoring on the monitoring data through two levels of security monitoring equipment and photovoltaic power station network switches. The security monitoring equipment is responsible for real-time monitoring of service data messages on the network, and the photovoltaic power station network switch is responsible for monitoring network access equipment conditions, physical link states and data flow information.

[0008] The dynamic strategy configuration module re-generates the data security monitoring rule configuration file, the security monitoring strategy configuration file and the switch forwarding configuration file according to the change of the SCD configuration file information and the security requirement information, so that the generated configuration file is more convenient to adjust and is updated in real time.

[0009] The code conversion module extracts the monitoring data, splits the monitoring data into single information, then names the single information, generates code data, and converts the first generated code data into the original code information library when generating the code data for the first time, and when splitting the monitoring data to generate the code data again, the code data is verified as the verification code information.

[0010] The integrity matching module extracts the information of the original code information library and the verification code information, and verifies the integrity of the verification code information by using the original code information library, and generates verification process information.
