The invention relates to a train positioning and protection method and system based on a satellite and a transponder and a medium. The method comprises the steps that S1, the position of a train in a station is determined according to satellite positioning; s2, obtaining a nearest relevant transponder group according to the determined position, and reporting position information of the train and the nearest relevant transponder group to a radio block center; s3, after receiving the positions of the train and the nearest relevant transponder group, the radio block center sends a driving permission to the vehicle-mounted equipment; s4, the train departs from the station according to the driving permission, an entity transponder of the same station track in the train departure direction is searched according to the obtained nearest related transponder group, if the entity transponder is received in an expected range, checking is passed, and the step S5 is executed, otherwise, checking is not passed; and S5, if the entity transponders in the expected range are received according to the step S4, performing consistency analysis and processing on the entity transponders. Compared with the prior art, the method has the advantages of high efficiency, accuracy and the like.

    本发明涉及一种基于卫星和应答器的列车定位及防护方法、系统及介质,该方法包括:S1、根据卫星定位确定列车在站内的位置;S2、根据确定的位置得到最近相关应答器组,并将列车和最近相关应答器组的位置信息汇报给无线闭塞中心;S3、无线闭塞中心收到列车和最近相关应答器组的位置后向车载设备发送行车许可;S4、列车根据行车许可发车出站,并根据得到的最近相关应答器组查找列车发车方向同股道的实体应答器,若在预期范围内收到该实体应答器,则校核通过并执行步骤S5,否则校核不通过;S5、若根据步骤S4收到的预期范围内的实体应答器,则对其进行一致性分析并处理。与现有技术相比,本发明具有高效、准确等优点。
