To detect movement of a two-wheeled vehicle by a theft or the like.SOLUTION: A communication device includes: a first communication part installed in a two-wheeled vehicle for continuing transmission and reception of a signal with a user terminal; an acceleration sensor for detecting acceleration of the two-wheeled vehicle; a timing setting part for setting a period when a signal is received in the first communication part as a stand-by period, setting a period when a signal is not received in the first communication part as a monitoring period, and setting a period when movement of the two-wheeled vehicle is detected by the acceleration detected by the acceleration sensor at a timing in the monitoring period as a tracking period; a position acquisition part for acquiring a present position of the two-wheeled vehicle when the monitoring period starts, and acquiring a present position of the two-wheeled vehicle during the tracking period; and a second communication part for transmitting a search request including the present position acquired by the position acquisition part to a server device during the tracking period, and transmitting alert data to the user terminal.SELECTED DRAWING: Figure 1
【課題】二輪車の盗難等による移動を検知する。【解決手段】通信装置は二輪車に設置され、ユーザ端末との間で信号の送受信を継続する第1通信部と、二輪車の加速度を検知する加速度センサと、第1通信部において信号を受信する期間をスタンバイ期間と設定し、第1通信部において信号を受信しない間をモニタリング期間と設定し、当該モニタリング期間のタイミングで加速度センサによって検出される加速度により二輪車の移動を検出する期間をトラッキング期間と設定するタイミング設定部と、モニタリング期間が開始すると、二輪車の現在位置を取得するとともに、トラッキング期間に二輪車の現在位置を取得する位置取得部と、トラッキング期間に、サーバ装置に位置取得部で取得された現在位置を含む捜索リクエストを送信するとともに、ユーザ端末にアラートデータを送信する第2通信部とを有する。【選択図】図1
