摘　　要：基于提高X射线检测仪稳定性与智能控制水平的目的,对其控制系统进行了设计。描述了该控制系统的组成结构,给出了电路原理图。整个控制系统由运动控制单元、高压控制单元以及面板控制单元组成,并采用微控制器、数字隔离器、CAN总线、冗余设计、高精度模数/数模转换器等器件与技术进行控制系统的硬件设计,从而保证了系统的稳定性与智能控制水平。描述了该控制系统的软件设计思想,给出了流程图。本控制系统已成功应用于X射线检测仪中,实验结果表明,该系统运行稳定可靠,达到X射线检测仪的控制要求。In order to improve the stability and intelligent control level of Automatic X-ray Inspection, the control system is designed. The hardware structure of control system is described and the circuit principle diagram is presented. The whole control system is composed of motion control unit, the high-voltage control unit and panel control unit. By using devices and technologies such as Microcontroller, digital isolator, CAN bus, redundancy design and high precision AD/DA converter, the system＇s stability and intelligent control is ensured. The software design in forms of flow chat is given in this paper. The control system is now successfully used in Automatic X-ray Inspection. Experiment results show that, the system is stable and reliable, able to meet the control requirement of the X-my inspection.
