互联互通中列车前方信号机状态判断方法
摘要：
本发明提供一种列车前方信号机状态判断方法，其方法包括：接收区域控制器发送的列车控制信息；获取列车的行驶位置信息；根据所述保护区段有效性信息、所述行驶位置信息和所述列车停靠位置信息获得第一防护距离和第二防护距离；根据所述第一防护距离和所述第二防护距离判断列车前方信号机状态。本发明提供一种列车前方信号机状态判断方法及装置，通过接收区域控制器发送的保护区段有效性信息和列车停靠位置信息，根据保护区段有效性信息、行驶位置信息和列车停靠位置信息获得第一防护距离和第二防护距离；根据第一防护距离和第二防护距离判断列车前方信号机状态，实现在互联互通中能够准确快速识别列车前方信号机状态的目的。
摘要（英）：

The invention provides a method for judging the state of a front annunciator of a train. The method includes the steps that train control information sent by a zone controller is received; traveling position information of the train is obtained; a first protection distance and a second protection distance are obtained according to protection zone section effectiveness information, the traveling position information and train stopping position information; and the state of the front annunciator of the train is judged according to the first protection distance and the second protection distance.The method and device for judging the state of the front annunciator of the train are provided, the protection zone section effectiveness information and the train stopping position information whichare sent by the zone controller are received, and the first protection distance and the second protection distance are obtained according to the protection zone section effectiveness information, thetraveling position information and the train stopping position information; and the state of the front annunciator of the train is judged according to the first protection distance and the second protection distance, and the purpose that the state of the front annunciator of the train can be accurately and quickly recognized in interconnection and intercommunication is achieved.
