Fault diagnosis system and method for x-ray generator for security inspection

Abstract

The invention discloses a fault diagnosis system and method of an X ray generator for safety check. The method at least comprises that S1) whether the X ray generator is started is determined, and thesubsequent steps are executed when the X ray generator is started; S2) a fault source is searched for concretely by determining whether positive and negative high voltage transformers and a voltage doubling circuit of the X ray generator are normal, determining whether a mineral oil of the X ray generator is leaked, and determining whether X ray tubes of the X ray generator are normal, and a stepS3) is executed if the no abnormity occurs in the three determining links; and S3) whether cables, fuses and an X ray controller of the X ray generator are normal is detected. Different parts of theX ray generator are detected in a targeted way by observing and smelling, a fault of the X ray generator for safety check equipment can be determined for accurately, the operational reliability of thesafety check equipment is improved, and it is ensured that safety check is smooth.

Description

technical field [0001] The invention belongs to the technical field of security inspection equipment systems, and in particular relates to a fault diagnosis system and method for an X-ray generator for security inspection. Background technique [0002] X-ray security inspection equipment (also known as security inspection equipment) is widely used in the security of important places such as airports, stations, ports, and large-scale events. These devices use X-rays to detect the items being inspected. X-ray generators are used to generate highly stable X-rays for security inspection equipment, and provide basic material conditions for X-ray scanning of inspected items. The X-ray generator has high power and high voltage, and some components in the circuit are under great stress. The X-ray tube is an electric vacuum device and has a certain service life. In addition, the use environment in some places is poor and lacks necessary maintenance. Therefore, there are many faults...

Problems solved by technology

[0015] Different faults of X-ray generators are often reflected in the same phenomenon, that is, no image is generated by the security inspection equipment or the image quality is poor

When the X-ray emission is unstable, the quality of the image will be affected; when the X-ray is not emitted, no image will be generated
