[0049] The 4G wireless communication unit is used to cooperate with the northbound unit to transmit the information encrypted by the security encryption unit to the power grid security access platform for decryption.

[0050] The hardware part of the lightweight information security transmission module integrates a 4G wireless communication module and a security encryption chip, and adopts a standard miniPCIe interface.

[0051] Specifically, the safe transmission process of electric power meteorological monitoring information implemented by the system of this embodiment includes the following two processes:

[0052] (1) The power meteorological monitoring terminal regularly reports and collects various meteorological monitoring data, including wind speed, temperature, humidity, air pressure, rainfall, light radiation intensity, video images and other monitoring information. The power meteorological monitoring terminal wakes up through the USB interface and transmits the monitoring information to the lightweight information security transmission module.

[0053] The main control unit of the lightweight information security transmission module performs protocol conversion, logic control, power consumption management, AI processing, encryption processing, etc.;

[0054] After being processed by the main control unit, the data passes through the security encryption unit and is hard-encrypted using the national secret algorithm;

[0055] The northbound unit uses the 4G wireless communication unit of the lightweight information security transmission module to transmit the encrypted data to the power grid security access platform for decryption. At this point, the data reaches the power grid information management area;

[0059] (2) The remote platform actively obtains the monitoring information of the meteorological monitoring terminal, and the grid enterprise-level meteorological service center issues a command to obtain the terminal monitoring information.

[0060] The video image information acquisition related commands are transmitted through the unified video monitoring platform of the power grid and the power grid security access platform, and the sensor status information acquisition commands are transmitted through the power grid Internet of Things management platform and the power grid security access platform to wake up the lightweight information security transmission module.

[0061] The main control unit of the lightweight information security transmission module performs decryption processing, protocol conversion, logic control and power consumption management, etc., wakes up the meteorological monitoring terminal,

[0062] After the meteorological monitoring terminal collects data, the monitoring information is sent to the power grid enterprise-level meteorological data service center through a lightweight information security transmission module.

[0063] The hardware part of the lightweight information security transmission module of this embodiment is designed based on the universal 4G module method, inheriting the universality of the 4G module and improving the functions and performance of the 4G module in various aspects. First, the integration of the module is improved, and a new security encryption chip is integrated on the same PCB board surface, so that it has the ability of security encryption on the basis of communication capability; second, the standard miniPCIe interface is adopted to improve the control and computing ability of the module. The universal 4G module only has the data transmission protocol of the communication layer.
