Motion control and diagnosis system for nuclear power in-service inspection automation device

Abstract

The invention discloses a motion control and diagnosis system for a nuclear power in-service inspection automation device, which comprises an electric control part, an emergency stop device and a cable connected with each component of the electric control part; an electric control box comprises a motion controller, a motor driver, an industrial computer, an analog quantity conversion module, an encoder module and a power supply module; the encoder module is electrically connected with the motor driver, and the motion controller receives a motion instruction output by the industrial computer, sends an electric signal to the motor driver to drive the motor to move, reads an encoder module signal and transmits the encoder signal to the industrial computer; the analog quantity conversion module converts the analog quantity in the motor driver into a voltage signal which can be read by the motion controller and then transmits the voltage signal to the industrial computer. An integrated design scheme is adopted, a motion controller and a motor driver are integrated, and the advantages of being easy and convenient to operate, small in size, rapid in connection and the like are achieved; various protection functions such as sudden stop protection and overcurrent protection are achieved, and damage to an original automatic device is prevented.

Description

technical field [0001] The invention belongs to the field of nuclear power testing equipment, in particular to a motion control and diagnosis system for nuclear power in-service inspection automation devices. Background technique [0002] Facing the growing development trend of nuclear power and the increasing demand for non-destructive testing, the frequency of in-service inspection automation devices for nuclear power is increasing. At the same time, the harsh environment of in-service inspections requires high-efficiency, high-load, and High stability and other requirements, combined with multiple on-site experience feedback, the current automatic inspection device is in a state of radiation contamination, it is difficult for personnel to detect abnormal motor functions at close range, and once a problem occurs, the cost of troubleshooting is high. Therefore, it is necessary to design a motion control and diagnosis system that can detect motion hidden dangers, monitor key...
