FIELD: mechanical engineering. ^ SUBSTANCE: protective system is implemented in the form of labour body, transferred by known path. System contains light-emitting facility, installed from one side of travelling part with ability of lighting of area nearby part of path, light detector, installed from the opposite side of travelling part with ability of receiving from light-emitting facility of light, passed through lighted area, and processing and control means. Processing and control means are implemented with ability of receiving of information from light detectors, and so recognition of presence at least one shadowy section, located in limits of lighted area and received by means of offset shadow to light detectors obstacles, located in lighted area. Processing and control means are implemented with ability of control of travelling part depending on specified information. Lighted area is lighted so that processing and control means allows information, enough for definition of shadowy section, or each shadowy section. ^ EFFECT: effectiveness increase of operation, ensured by restriction of dangerous area nearby the motion path of labour body. ^ 50 cl, 10 dwg |
