[0002] The X-ray irradiator is an artificial electronic device capable of producing high-energy X-rays. It is used in biology for cell culture, blood product irradiation, etc. Its important components include a high-voltage DC power supply for the X-ray tube, and the device outputs a filament DC voltage and high-voltage DC voltage, in which the filament DC voltage is 0-10V, the current is 0-10A, the output high-voltage DC voltage is 0-160KV, the current is 0-20mA, and the power can reach 3200W, and the internal structure and principle are complex, and the test procedure in the manufacturing process It is cumbersome, and there is a certain risk of electric shock to the debugging personnel. The usual debugging step is to use the whole machine operation panel (PLC + touch screen) of the X-ray irradiator to carry out joint debugging of the whole machine after the power supply is produced, which requires design programs, touch screen configuration, To control X-ray tubes, process flow, data storage, communication, etc., it is also necessary to design shells, installation diagrams, wiring diagrams, and make cables, etc. After the number of components increases, it is difficult to distinguish the fault point, which brings inconvenience to the joint debugging of the whole machine; "Research on Multi-channel Signal Detection and Storage Based on PLC+Touch Screen Technology" in Issue 4 of 2016 of "Magazine" introduced the system structure of PLC+ touch screen technology for testing temperature switches, but did not mention the structural design of testing high-voltage DC power supply
