Light curtain safety detecting device

Abstract

The invention discloses a light curtain safety detecting device. The light curtain safety detecting device is characterized by comprising a light curtain 1, a controller 3, a detecting circuit 2, a safety touch plate 5 and a conversion circuit 4, and is characterized by further comprising a detector, a driving mechanism, a transmission mechanism, a control module and a light beam position detecting unit; the detector includes an emitter and a receiver; the transmission mechanism is connected with the driving mechanism; an input end of the detecting circuit is connected with an output end of a light curtain body; an output end of the detecting circuit is connected with an input end of a microprocessor; an output end of the microprocessor is connected with an input end of the safety touch plate after serially connecting with the conversion circuit; and the microprocessor adopts an MCU. The light curtain safety detecting device is simple in structure, attractive in design, simple in installation and debugging and wide in application, widens the light curtain detecting coverage range, even can achieve no detecting blind area through control of the driving mechanism, and greatly improves the elevator safety.
