CONTACT SENSING SYSTEM, DEVICE SLAVE UNIT THEREOF, DEVICE MASTER UNIT THEREOF, AND CONTACT SENSING METHOD
To provide a contact sensing system, a device slave unit thereof, a device master unit thereof, and a contact sensing method making it possible to quickly and easily grasp the location of an accident caused by contact with a pole that separates traffic.SOLUTION: In a contact sensing device slave unit, an acceleration sensor 150 outputs detection coordinate information, which is position information of a pole detected only when it is attached to the pole and detects acceleration beyond a certain level, and a wireless communication unit 140 wirelessly communicates pole identification information and detection coordinate information for identifying the pole; and in a contact sensing device master unit, a wireless communication unit wirelessly communicates with the wireless communication unit 140 to receive the detected coordinate information and the pole identification information, an angle calculation unit calculates an inclination angle of the pole based on a mounting coordinate information which is the previously stored position information at the time of mounting the pole and the coordinate information received via the master unit side wireless communication means, and an accident determination unit determines that the pole has been contacted when the inclination angle is greater than or equal to a preset threshold value.SELECTED DRAWING: Figure 1
【課題】通行を分離する支柱に接触することで生じてしまった事故の場所を早急かつ簡易に把握できる接触検知システム、その装置子機、その装置親機、および接触検知方法を提供する。【解決手段】接触検知装置子機で、加速度センサー１５０が、支柱に取付けられて一定以上の加速度を検知したときのみ検出した支柱の位置情報である検出座標情報を出力し、無線通信部１４０が、支柱を識別する支柱識別情報と検出座標情報とを無線で通信し、接触検知装置親機で、無線通信部が、無線通信部１４０と無線で通信して検出座標情報と支柱識別情報とを受信し、角度計算部が、あらかじめ記憶された支柱の取付時の位置情報である取付座標情報と親機側無線通信手段を介して受信した座標情報とに基づいて支柱の傾斜角度を算出し、事故判断部が、傾斜角度があらかじめ設定された閾値以上であった場合に、支柱に接触があったと判断する。【選択図】図１
