Abstract
The invention discloses an open-typed cable start-stop working safe device in the single-chip set technique appliance domain, which consists of infrared inductive device and switch pipe executing structure, wherein the I-to-O input end of single-chip set connects the output end of infrared launching and receiving device and the I-to-O output end of single-chip set connects the switch pipe executing structure, which contains switch pipe and relay; the single-chip set receives the body inductive signal of passenger, which outputs the detecting signal through single-chip set controlling the switch pipe executing structure. The invention can control the start-stop time of operating motor, which guarantees the body safety.
Description
Technical field the invention relates to a kind of open cable car start-stop operation safety device, and particularly a kind of infrared ray provides the open cable car start-stop operation safety device of monitor signal, belongs to microchip technology field.
Before background technology the invention applying date, open cable car does not have monitoring device when left alone without help opening, and the people does not occupy stably or left alone without help following time does not start again when the people leaves safely when starting, and causes dangerous sunken trouble to taking the cable car visitor.
The purpose of summary of the invention the invention provides the open cable car start-stop operation safety device that a kind of infrared ray provides monitor signal.
The invention solves the technical scheme that its technical matters adopts: comprise infrared induction device and switching valve execution architecture; The input end of single-chip processor i/o is connected with the receiving device mouth with infrared, and the mouth of single-chip processor i/o is connected with the switching valve execution architecture, and the switching valve actuating unit comprises switching valve and relay.Infrared and receiving device are connected to form by infraluminescence pipe, infrared receiving tube, pulse square wave voltage generator, transport and placing device, demoder.
The invention solves its beneficial effect: the invention is by the human-induced signal of micro controller system reception passenger, by Single-chip Controlling switching valve execution architecture output detection signal.When worn-out open type cable car opens left alone without help operation,, the time-delay start-stop time of the moving operation of control motor, guarantee personal safety by monitoring visitor induced signal.
Description of drawings is described further the invention below in conjunction with accompanying drawing.
