<p>PROBLEM TO BE SOLVED: To provide a monitoring system which easily monitors worker's approach to dangerous object or the like independently of the work mode of the worker. SOLUTION: A recursive light reflector 2 which can be set to a worker 1, a position detector 3 which emits laser light L' to the worker 1 and receives reflected laser light R reflected by the light reflector 2 to measure the distance to the light reflector 2 and detects the angle of emission of laser light L' to detect the position of the worker 1, and an alarm device 10 which generates an alarm at the time when the worker position detected by the position detector 3 is within a prescribed alarm range are provided.</p> |
