本発明は、突風や地震などによる突発的な災害から列車の安全を守るための車上にて情報を集約する高度列車安全制御システムに関するものである。   The present invention relates to an advanced train safety control system that collects information on a vehicle for protecting the safety of a train from a sudden disaster such as a gust or an earthquake.

従来、自然災害時に列車走行の安全を確保するために、沿線に設置した各種センサからのデータや、駅員、運転士及び外部機関からの情報を収集し、運転規制の発令や規制解除・運転再開の判断に利用している（下記特許文献１〜３参照）。この時、情報の信頼性の観点から、判断に用いる重要な情報は、事業者独自で収集したものを用いることが多い。例えば、地上に設置されたセンサにより観測されたデータの値が、あらかじめ定められた基準値を超えた場合、指令員の判断で一定の区間にわたって列車運転の中止や徐行、運転再開などの判断が行われている。   Conventionally, in order to ensure the safety of train travel in the event of a natural disaster, data from various sensors installed along the railway line and information from station staff, drivers, and external organizations are collected to issue operation regulations, release regulations, and resume operations (Refer to Patent Documents 1 to 3 below). At this time, from the viewpoint of reliability of information, important information used for judgment is often collected by the operator. For example, if the value of the data observed by a sensor installed on the ground exceeds a predetermined reference value, the commander's judgment may determine whether to stop or slow down train operation, resume driving, etc. Has been done.
