The invention provides a virtual section occupation inspection method which comprises the following steps that: a radio block center acquires a train position report and acquires the position and distance deviation value of a nearest related transponder group in the train position report, and the radio block center acquires the train head position based on the position and distance deviation valueof the nearest related transponder group; the radio block center acquires the train tail position; the wireless block center judges whether a turnout exists between the train head position and the train tail position or not, if yes, the wireless blocking center obtains interlocking data and judges the opening state of the turnout based on the interlocking data, and the wireless block center obtains a virtual section occupied by the train based on the train head position, the train tail position and the opening state of the turnout; and judging whether the turnout exists in the train safety envelope or not, if yes, acquiring interlocking data by the wireless block center, judging the opening state of the turnout based on the interlocking data, and obtaining a train walking track accordingto the opening state of the turnout, thereby judging a virtual section where the safety envelope is located.

    本发明提出一种虚拟区段占用检查方法,无线闭塞中心获取列车位置报告,并获取列车位置报告内最近相关应答器组的位置和距离偏移值,无线闭塞中心基于最近相关应答器组的位置和距离偏移值获取列车车头位置;无线闭塞中心获取列车车尾位置;无线闭塞中心判断车头位置和车尾位置之间有无道岔,若有道岔,无线闭塞中心获取联锁数据,基于联锁数据判断道岔开向状态,无线闭塞中心基于车头位置、车尾位置和道岔开向状态获取列车所占虚拟区段;判断列车安全包络内有无道岔,若有道岔,无线闭塞中心获取联锁数据,基于联锁数据判断道岔开向状态,通过道岔开向状态得出列车行走轨迹,从而判断安全包络所处的虚拟区段。
