Power consumption information acquisition system safety isolation gateway and application method thereof

Abstract

The invention relates to a power consumption information acquisition system safety isolation gateway and an application method thereof; the safety isolation gateway comprises the following units: an internal network processing unit used for receiving a message sent by an acquisition server, sending packaged pure application data to an isolation exchange unit, and receiving the data transmitted by an external network processing unit from the isolation exchange unit; the external network processing unit used for receiving the message sent by the acquisition terminal, sending the packaged pour application data to the isolation exchange unit, and receiving the data transmitted by the internal network processing unit from the isolation exchange unit; the isolation exchange unit arranged between the internal and external network processing units and used for storing the pure application data transmitted by the internal and external network processing units, thus realizing controllable exchange of the pure application data between the internal and external network processing units; a code processing unit used for carrying out code protocol inspection for the data processed by the isolation exchange unit in a flow pass mode, and providing code examination and decryption services.

Description

technical field [0001] The present invention relates to the technical field of information security, and more specifically, to a safety isolation gateway used in a power consumption information collection system. Background technique [0002] The electricity consumption information collection system is a key business system in the electricity consumption infrastructure of residents and enterprises. The system can realize electricity consumption monitoring, implementation of ladder pricing, load management, Line loss analysis, and ultimately realize the purposes of automatic meter reading, peak shifting power consumption, power consumption inspection (anti-power theft), load forecasting, and power cost saving. [0003] Since the master station of the acquisition system collects the electricity consumption information of multiple users, and also undertakes important tasks such as controlling the opening / closing of the user's electric meter and distributing power price informat...

Problems solved by technology

At present, the electricity consumption information collection system has used cipher machines and ESAM chips to encrypt and protect the downlink control and parameter setting commands at the application layer. Since the power consumption information collection system mostly uses wireless networks as the transmission channel between the master station and the terminal, the openness of the network Strong, the communication link between the main station and the terminal lacks protection measures, and there is a risk of interception, forgery, and tampering of the transmitted data. It is urgent to add a special security isolation gateway in the safe access area at the border of the main station of the acquisition system. To ensure the safe and reliable operation of the electricity collection system
