Abstract

The invention relates to a circuit control system of an X-ray inspection instrument. The circuit control system of the X-ray inspection instrument is formed by four parts, namely, a control circuit, a power circuit, a high-voltage control circuit and a photovoltaic conversion circuit. The control circuit achieves the software processing of digital images, display, management, communication, the management of battery supply, high-voltage control and motor running control. The power circuit achieves the three power supply ways of alternating current power supply, direct current power supply and lithium battery power supply. The high-voltage control circuit is in charge of supplying high voltage and filament current for an X-ray bulb tube, and achieves the collection of the environment temperature and the control of the voltage and the current of an X-ray light tube. The photovoltaic conversion circuit can convert visible light to digital image signals through a charge coupled device (CCD) camera and transmits the signals to an advanced RISC machine (ARM) to process. The circuit control system of the X-ray inspection instrument achieves the relative independence of each unit of the control system, the connection wires among all units are simple and tidy, and the high requirements for reliability and flexibility of the control system of the X-ray inspection instrument are met.

Description

technical field [0001] The invention relates to a circuit control system of an X-ray inspection instrument, in particular to a circuit control system of an X-ray inspection instrument. Background technique [0002] With the continuous development of photoelectric technology and the promotion of Internet of Things technology, the shortcomings of some portable X-ray inspection instruments are also highlighted, for example: the effective field of view is small, which makes it difficult to see the images of some parts of the object; it does not support a large amount of data Storage; remote control cannot be realized, or remote control cannot be realized in a wireless state; independent power supply capability is not supported. These above problems have greatly reduced the flexibility and independence of the portable X-ray inspection instrument, making its portable ability not manifest. Contents of the invention [0003] Aiming at the existing problems and the present situati...
