多联锁共享室外信号设备切换控制电路设计
Design of Switching Control Circuit for Outdoor Signal Equipment Shared by Multiple Interlocking Systems
摘要
Abstract
In the construction of practical training bases for signaling systems,there is a need for switching the control by multiple interlocking systems over one set of outdoor signal equipment at the station,to reduce the repetitive construction,site occupation and capital investment of outdoor equipment.Based on the relay logic circuit method,a switching control circuit is designed to allow five interlocking systems to share one set of outdoor signal equipment at the station.The multiple interlocking systems are physically excluded,and only one interlocking system can control the outdoor signal equipment at the station at a time.In the event of any fault of the switching control circuit,each interlocking system can operate independently.The button circuit is designed to achieve the switching selection and control of two buttons;and the indicator circuit is designed to display the interlocking type and status of the current interlocking system that controls the indoor and outdoor equipment.The tests indicate that the proposed circuit can meet the requirements for switching the control by multiple interlocking systems over one set of outdoor signal equipment,and that it has certain promotion value.关键词
