The invention discloses a train block partition calculation occupation method and system based on satellite positioning, and the method comprises the following steps: S1, calculating the real-time speed and position of a train, and combining the position of a train antenna and the length of the train according to the real-time speed and position of the train, obtaining the positions of the worst front end WCA of the train, the worst rear end WCB of the train and the worst locomotive tail WCLP of the train; S2, according to the integrity state of the train and the positions of the WCA, the WCB and the WCLP, obtaining corresponding block partition occupation information in combination with electronic map information; and S3, after the WCB enters a new block partition, inquiring the train tail state, if it is inquired that the train tail pipe pressure is high, sending a corresponding block partition clearing message by a vehicle-mounted computer to the radio block center, if it is inquired that the train tail pipe pressure is low, reporting that the train integrity is lost by the the vehicle-mounted computer to the radio block center RBC, and performing LOI blocking on the corresponding block partition by the radio block center.

    本发明公开了一种基于卫星定位的列车闭塞分区计算占用方法和系统,包括如下步骤:S1,计算列车的实时速度和位置,并根据列车的实时速度和位置,结合列车天线位置及列车长度,得出列车最不利前端WCA、列车最不利后端WCB和列车最不利机车尾部WCLP的位置;S2,根据列车的完整性状态以及WCA、WCB和WCLP的位置,并结合电子地图信息得出对应的闭塞分区占用信息;S3,WCB进入新的闭塞分区后,查询列尾状态,若查询到列尾管压为高压,车载计算机向无线闭塞中心发送相应闭塞分区出清的消息,若查询到尾管压为低压,车载计算机向无线闭塞中心RBC报告列车完整性丢失,无线闭塞中心对相应的闭塞分区进行LOI封锁。
