摘　　要：轨道占用状态是列控系统保证铁路行车安全的基础信息,全国铁路自动闭塞区段均以轨道电路作为列车占用检查设备,由于线路钢轨与轮对间分路电阻达不到规定要求,存在列车占用检查功能失效可能,产生安全隐患。提出一种基于车载设备(ATP)向无线闭塞中心(RBC)发送的列车位置报告实现列车占用检查,降低轨道电路分路不良风险的方法,并对模型的应用效果进行对比分析。Track occupancy status is basic information for the railway traffic safety. All automatic block sections of the national railways are depending on track circuits as train occupancy inspection equipment. If the shunt resistance between the rail and wheel can＇t meet requirements, it may cause train occupancy inspection function failure and result in potential safety problems. For reducing risks of track circuit shunting loss, the paper introduces a method of realizing the train occupancy inspection based on onboard equipment（ATP） sending the train location report to the radio block center（RBC）, and gives the comparison and analysis of the application effect of the model.
