Patent attributes
A surroundings monitoring system for a work machine includes a detecting part to detect a monitoring target around the work machine and a control part to switch the state of the work machine between first and second states based on the detection result. The first state includes a state where a restriction on the operation of the work machine is canceled or a state where an alarm is stopped. The second state includes a state where the operation is restricted or stopped or a state where the alarm is output. The control part returns the state of the work machine to the first state when a predetermined condition is satisfied after switching the state to the second state. The predetermined condition includes that no monitoring target is detected around the work machine and that it is ensured that the work machine is prevented from starting to operate.
