Abstract

The invention provides an intelligent socket system special for a nuclear power SIP test. The intelligent socket system comprises a man-machine interaction device and an intelligent socket box; a PLC (Programmable Logic Controller) and a plurality of contactors connected with the PLC are arranged in the intelligent socket box; the PLC is in communication connection with the man-machine interaction device; the man-machine interaction device is used for collecting user information when receiving a nuclear power SIP test instruction of a user, verifying a user identity based on the user information, determining a user permission, and sending the user information and the user permission to the PLC; the PLC controls the on-off of each contactor according to the user permission; and an identity verification function is provided, in addition, each switch has strict opening and closing permission, so that a control box is prevented from being operated by unauthorized personnel.

Description

technical field [0001] The invention belongs to the field of electric power application and security encryption, and relates to a special intelligent socket system for nuclear power SIP test and a safety protection method thereof. Background technique [0002] The nuclear power SIP test uses methods such as system identification and pattern recognition to verify the system, which is of great significance to the normal and safe work of nuclear power plants, and also has a promotional effect on the safety verification of high-level and high-level systems. However, because the SIP system is A protection system, that is, the SIP is only active in the event of an accident transient in the reactor, and its failure is concealed in the normal operation of the reactor. In order to find faults in time to ensure the availability of the SIP system, regular tests must be carried out on the SIP system. [0003] The special socket box for nuclear power SIP test originally used a mechanica...
