To provide a railroad signal facility monitoring support program for a railroads-monitoring device in which many people can check facility status information in parallel in spite of the limitation of parallel processing of information requests because an information collection is carried out by sequentially-polling type communication.SOLUTION: A railroad signal facility monitoring support program comprises: an information-request representing program 31 for forwarding an information request received from a portable terminal 21 toward a detector 19; a primary response processing program 32 for determining the presence or absence of a secondary response; and a secondary response processing program 33 for returning facility status information received from the detector 19 to the portable terminal 21. The railroad signal facility monitoring support program also comprises: a request integration program 43 for excluding a prior information request sent to the same detector from a forwarding target; and a simultaneous report return program 44 for adding a posterior information request sent to the same detector to a return target, whereby the congestion of a dedicated communication channel is avoided because a posterior collection is omitted by narrowing down a prior collection when the information requests are overlapped in the same detector 19, and in addition, collected information is returned promptly to any of the prior/posterior portable terminals 21 after the prior collection.SELECTED DRAWING: Figure 1

    【課題】鉄道用監視装置が情報収集を順次ポーリング式通信で行うため情報要求の並行処理に制約があっても多数の者が並列的に設備状態情報を確認できるようにする。【解決手段】携帯端末21からの情報要求を検出器19に向けて転送する情報要求代行プログラム31と、二次応答の有無を判別する一次応答処理プログラム32と、検出器19からの設備状態情報を携帯端末21へ返送する二次応答処理プログラム33を備えた鉄道信号設備監視支援プログラムにおいて、同じ検出器への先行情報要求を転送対象から除外する要求集約プログラム43と、同じ検出器への後行情報要求を返送対象に加える同報返送プログラム44とを設ける。これにより、同一の検出器19に対して情報要求が重複したときには先行収集に絞り込まれて後行収集が省かれるので専用通信回線の混雑が回避されるうえ、先後いずれの携帯端末21にも先行収集後速やかに収集情報が返送される。【選択図】 図1
