Electric valve state detection system and method

Abstract

The invention relates to the technical field of electric valve state detection and relates to an electric valve state detection system and method. According to the system, a signal detecting unit is connected with a sensor unit and a data processing unit; the signal detecting unit collects a plurality of parameter signals through the sensor unit, and transmits the signals to the data processing unit for performing corresponding processing; a power source module and management unit is connected with the sensor unit, the signal detection unit and the data processing unit and provides a direct-current power source for the sensor unit, the signal detection unit and the data processing unit; the power source module and management unit communicates with the data processing unit through a serialport; and an upper computer is connected with the data processing unit through an Ethernet or wireless network, so that the upper computer can control the data processing unit. With the system adopted, the performance status of an electric valve can be comprehensively and accurately analyzed under a premise that the electric valve is not disassembled and disassembled; maintenance personnel can beguided to adjust the valve to be in an optimal state; state performance verification can be performed on the repaired electric valve; and human errors can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of electric valve state detection, and in particular relates to an electric valve state detection system and method. Background technique [0002] In nuclear power plants, a switch failure of an isolation boundary valve (usually an electric isolation valve) will cause serious safety accidents and economic losses. In order to ensure safe shutdown, some electric isolation valves must be opened in emergency situations, and others must be closed to ensure system isolation or prevent radioactive leakage. It is the most concerned valve in nuclear power plants. At present, most nuclear power plants use routine inspection, periodic inspection, component replacement or overall replacement to carry out preventive maintenance, and corrective maintenance (mainly disassembly maintenance) is carried out after obvious faults are found. Rarely, there are phenomena such as misrepair, omission, and overrepair, and human erro...

Problems solved by technology

At present, most nuclear power plants use routine inspection, periodic inspection, component replacement or overall replacement to carry out preventive maintenance, and corrective maintenance (mainly disassembly maintenance) is carried out after obvious faults are found. Rarely, there are phenomena such as misrepair, missed repair, over repair, etc., and human error cannot be avoided, causing great safety hazards to the operation of nuclear power plants
