摘　　要：针对闸机通行逻辑算法数据处理复杂、实时性差等问题,设计红外识别闸机控制系统。该系统集成了通行逻辑、闸门控制、声光报警等功能;引入红外传感识别技术,结合旅客通行事件集,优化闸机通道传感器布局;基于位置识别思想,设计通行逻辑算法;采用32位AdvancedRISC Machine(ARM)微控制器,作为主控芯片。在国家铁路多个客运车站应用的结果表明,该系统误报率低,旅客行为检测精准,通行效率高,验证了其可靠性与实用性。This paper designed an infrared recognition gate control system to address issues such as complex data processing and poor real-time performance of the gate traffic logic algorithm.The system integrated functions such as traffic logic,gate control,sound and light alarm,etc.Combining with passenger traffic event sets,the paper introduced infrared sensing recognition technology to optimize the sensor layout of the gate traffic,based on the idea of location recognition to design a traffic logic algorithm,and used a 32-bit Advanced RISC Machine(ARM)microcontroller as the main control chip.The results of application in multiple passenger stations of the national railway show that the system has a low false alarm rate,accurate passenger behavior detection,and high traffic efficiency,which verifies its reliability and practicality.
