摘　　要：目前应用于地铁站台门的门控器(DCU)多采用CAN-bus现场总线进行通讯。现在国内外市场中,各品牌DCU产品多采用手动方式逐个设置ID,这种设置方式调试效率低下、人工成本高。本文提出了一种可动态配置CAN总线节点ID的技术:只需要整侧DCU全部上电即可实现所有DCU的ID自动配置。该技术摒弃了以往DCU逐个设置ID的缺点,可有效提高调试人员的调试效率。At present, The door controllers(DCU) used in subway platform doors mostly use CAN-bus field bus for communication.At present in domestic and foreign markets, each brand of DCU products uses manual methods to set the ID one by one,which results in low debugging efficiency and high labor costs. This paper proposes a technology that can dynamically configure the CAN bus node ID: all the DCU need to be powered on to realize the automatic ID configuration of all DCU.This technology abandons the shortcomings of setting ID one by one in the DCU in the past, which can effectively improve the debugging efficiency of the debugger.
