The invention discloses a train temporary speed limit information sending system and a train temporary speed limit information sending method. The train temporary speed limit information sending system comprises radio block center equipment, temporary speed limit server equipment and vehicle-mounted equipment. The radio block center equipment periodically sends authorization information containing idle track section information to the vehicle-mounted equipment; the vehicle-mounted equipment judges whether the received authorization information is updated or not, speed limit request information containing authorized track section information of the train is generated according to the updated authorization information, and the updated speed limit request information is sent to temporary speed limit server equipment; and the temporary speed limit server device calculates speed limit information according to the updated speed limit request information and sends the speed limit information to the vehicle-mounted device. The temporary speed limiting server device generates the speed limiting information according to the train authorization information and the centralized dispatching system, and directly sends the speed limiting information to the vehicle-mounted device, so that the function redundancy between devices is reduced, the function coupling between subsystems is reduced, and the overall efficiency of the train control system is improved.
本发明公开了一种列车临时限速信息的发送系统及发送方法,包含:无线闭塞中心设备、临时限速服务器设备、车载设备。所述无线闭塞中心设备周期性发送包含空闲轨道区段信息的授权信息给车载设备;所述车载设备判断接收到的授权信息是否发生更新,根据更新的授权信息生成包含列车被授权的轨道区段信息的请求限速信息,将更新的请求限速信息发送给临时限速服务器设备;所述临时限速服务器设备根据更新的请求限速信息计算限速信息,并将所述限速信息发送至车载设备。本发明通过临时限速服务器设备根据列车授权信息和调度集中系统生成限速信息,并直接发送至车载设备,减少设备间功能冗余,降低子系统间的功能耦合,提高列车控制系统的整体效能。
