| description | Light barriers are the key parts of X-ray security inspection equipment, which are used in large amount and cost a lot. In order to reduce the cost, increase the performance and reduce the dependence on the purchased products, a light barrier design scheme is proposed in this paper. According to the specific application requirements of the security inspection machine, a single clock source and a fixed phase difference transmitting and receiving mode are adopted, and low-cost components are selected to realize the reliable anti-interference of multiple light barriers in the security inspection machine; the automatic gain control function and self-test function are designed, and the system wiring is simplified through the optimized interconnection interface, so the performance of the whole machine is further improved. After batch application, the price is only one tenth of the original system, which effectively reduces the production cost of the security inspection machine. |
