摘要
为提高磁性停车系统的安全性、可靠性,使系统的防护功能更加完善,提出一种新型磁性停车系统方案。新型磁性停车系统采用霍尔器件对地面磁场进行感应,实现故障-安全架构,主机单元进行安全冗余设计,新增列车定位功能、车门防护功能以及速度监控功能,与既有磁性停车系统相比,新型磁性停车系统可提高系统的可靠性、安全性以及可维护性。
In order to improve the safety and reliability of the magnetic stop system,and make the protection function of the system more perfect,this paper proposes a new type of magnetic stop system.The new magnetic stop system uses Hall devices to sense the wayside magnetic field,achieving Fail-Safe architecture.The host unit is designed for safety and redundancy.The train positioning function,door protection function and speed monitoring function are added.Compared with the existing magnetic stop system,the new magnetic stop system improves the reliability,safety and maintainability of the system.
