  • Patent number: 11135975
    Abstract: A periphery monitoring device includes cameras that detects a periphery of a hydraulic shovel, a periphery monitoring monitor that displays a bird's-eye image based on image information acquired by the cameras, and a state switching control unit that controls mode switching between a periphery monitoring mode and a monitoring pause mode. The state switching control unit transitions to the periphery monitoring mode in a case where an input of a key-on manipulation with respect to the hydraulic shovel is received in the monitoring pause mode. In the monitoring pause mode, it is possible to transition to the periphery monitoring mode in time faster than transition from a power-OFF state.
