To provide a safety system of a work machine which can accurately detect an object located around the work machine with reduced processing load.SOLUTION: A safety system comprises an object detection device 60 and a controller 70. The object detection device 60 includes a forward object detection unit 60A that covers a detection range in the front side of the upper revolving body 12, and a rear object detection unit 60B that covers a detection range in the back side of the upper revolving body 12. Number of pixels per unit angle for the forward object detection unit 60A is set to be greater than the aforesaid pixel number for the rear object detection unit 60B. A first monitoring area A1 located in the front side of the upper revolving body 12 corresponding to the forward object detection unit 60A, and a second monitoring area A2 located in the rear side of the upper revolving body 12 corresponding to the rear object detection unit 60B having a less depth than the aforesaid first monitoring area in the view from the upper revolving body 12, are set.SELECTED DRAWING: Figure 2
【課題】処理負荷を低減しつつ、作業機械の周囲に位置する対象物を精度良く検出することが可能な作業機械の安全装置を提供する。【解決手段】安全装置は、対象物検知器60と、コントローラ70と、を備える。対象物検知器60は、上部旋回体12の前方の検知範囲を有する前対象物検知器60Aと、上部旋回体12の後方の検知範囲を有する後対象物検知器60Bとを含み、前対象物検知器60Aの単位角度あたりの画素数は後対象物検知器60Bの前記画素数よりも大きく設定されている。また、前対象物検知器60Aに対応して上部旋回体12の前方に設定された第1監視領域A1と、後対象物検知器60Bに対応して上部旋回体12の後方に設定され上部旋回体12から見て前記第1監視領域よりも小さい奥行きを有する第2監視領域A2とが設定されている。【選択図】図2
