摘　　要：针对嘉兴站上行出站信号机存在的标准点灯电路不能满足现场需求的问题,根据现场需求提出点灯电路的修改方案,并对修改方案进行验证。根据现场需求分析嘉兴站上行出站信号机标准点灯电路存在的不足;提出电路的修改方案;对修改方案中电路功能逻辑逐一进行方案验证;对修改设计的要点进行归纳。结果表明,修改后的电路符合“故障-安全”原则,能够有效的满足嘉兴站现场的实际需求。In order to solve the problem that the standard lighting circuits of the up-direction starting signals of Jiaxing railway station cannot meet the demands of the site, a modification plan of the lighting circuits is proposed according to the site requirements, and the modification plan is verified.Firstly, according to site requirements, this paper analyzes the shortcomings of the standard lighting circuits as mentioned above;secondly, the circuit modification plan is proposed;then, the circuit function logic in the modified plan is verified in different scenarios one by one;finally, the key points of the modified design are summarized. The results show that the modified circuits comply with the “fail-safe” principle and can effectively meet the actual demands of Jiaxing railway station.
