摘　　要：介绍了一种X射线管高频高压电源智能控制系统,该系统以PLC(programmable logic controller)为控制核心内核,结合高压和灯丝2路PID(proportional-integral-derivative control)电路,实现对高频高压电源的智能化控制。采用手动、自动2种控制模式,在工作中使用按钮进行模式选择。自动模式采用MCGS昆仑通态触摸屏作为上位机,进行开关控制以及保护数据的设置,实时显示工作数据。手动模式采用按钮进行开关控制,编码器对高压、束流和时间的数值进行设置,数码管实时显示工作数据。测试结果表明,手动、自动模式均能实现对高频高压电源的控制,同时系统能实现高压束流连续可调,实现过压欠压、过流欠流、温度流量、功率和供电保护以及倒计时等功能。此系统具有操作简单、精度高、工作稳定、快速保护等优点,具有良好的研究价值与应用前景。The intelligent control system of high-frequency and high-voltage power supply for X-ray tubes is introduced in the paper.The system utilizes a PLC as the control core and integrates two PID circuits for high voltage and filament to enable intelligent control of high frequency and high voltage power supply.Two control modes,manual and automatic,are implemented.The mode selection is done using a button during operation.In the automatic mode,an MCGS Kunlun on-state touch screen serves as the upper computer to control the switch,configure protection data,and display real-time working data.On the other hand,the manual mode employs buttons for switch control,an encoder to set values for high voltage,beam current,and time,and a digital tube to display real-time working data.Test results demonstrate that both automatic and manual modes are capable of controlling the high frequency and high voltage power supply.Furthermore,the system allows for continuous adjustment of high voltage beam and offers various protection functions such as overvoltage,undervoltage,overcurrent,undercurrent,temperature,flow,power,and power supply protection,along with a countdown feature.This system is characterized by simple operation,high precision,stable performance,fast protection response,and holds promising application prospects and research value.
