To provide a worker watching system capable of notifying the surroundings of presence of working mobile equipment or presence of a worker without giving excessive stress to a worker or a driver.SOLUTION: When a vibration detector 13 of a communication terminal 10 for mobile equipment detects a vibration of an internal combustion engine being a prime mover of working mobile equipment 40 and a movable state detection section 12 outputs a movable signal to a beacon signal generator 11, a first beacon signal generator 11 generates a first beacon signal having radio wave intensity higher than that of a first beacon signal when a movable signal has not being input. In each one of communication terminals 20a, 20b, ...20n for workers, a first danger determination section 22 determines presence/absence within a danger range based on radio wave intensity of the first beacon signal that has received by a first beacon signal reception section 21. Thus, only necessary alarm is issued by changing a largeness of a danger range based on whether the working mobile equipment 40 is in a moving state or in a movable state.SELECTED DRAWING: Figure 1

    【課題】作業者又は運転者に過度のストレスを与えることなく、周囲に作業用移動機器があること又は作業者がいることを知らせることができる作業者見守りシステムを提供する。【解決手段】移動機器用通信端末器10の振動検出器13が作業用移動機器40の原動機である内燃機関の振動を検出して、移動可能状態検出部12がビーコン信号発生器11に移動可能信号を出力すると、第1のビーコン信号発生器11は移動可能信号が入力されていないときの第1のビーコン信号よりも強い電波強度の第1のビーコン信号を発生する。作業者用通信端末器20a、20b…20nは第1のビーコン信号受信部21が受信した第1のビーコン信号の電波強度に基づいて第1の危険判定部22が危険範囲内にいるか否かを判定するので、作業用移動機器40が移動中又は移動可能状態にあるか否かで危険範囲の広さを変更することによって、必要な警報のみを発するようにする。【選択図】 図1
