【 摘 要 】

In recent years, the safety situation around the world is very serious. Each country has higher quality requirements for walk-through metal detector, and the newly issued standards are stricter. It has required precise and detailed testing work. Therefore, an automatic test system was designed to meet the requirements. The system was an AC servo system based on PC+PLC, with the control core of PLC and three-dof motion platform composed of servo motor and linear module to perform slide components. The paper focused on the overall architecture, structure design, working process, hardware composition, PLC programming and software functions of the system. The system has no interference to the testing work of metal detector with good testing ability and high positioning accuracy. The system improves the accuracy of the testing, and provides a friendly man-machine interface, which greatly reduces the working intensity of testers.
