Abstract
The invention relates to a safety device of open cable car that uses gate circuit to detect signal, belonging to the technique of single chip. Wherein, it comprises an infrared device, pyroelectric crystal or gate circuit sensor, and a switch tube; it is characterized in that: the input of single chip I/O is connected to the output of emitting-receiving device of OR circuit; the output of single chip I/O is connected to the executor of switch tube; said executor comprises a switch tube and a relay. The invention uses single chip to receive the body sensitive signal of user, and via single chip to control the executor to output the detect signal of OR circuit. The invention has the advantages that: when the open cable car works, the OR circuit detects the body sensitive signal of user, to control the delay start-stop signal of motor, to confirm the safety. In addition, the OR circuit can improve the detecting accuracy.
Description
Technical field the invention relates to a kind of open cable car start-stop operation safety device, and particularly a kind of OR circuit 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 OR circuit provides monitor signal.
The invention solves the technical scheme that its technical matters adopts: comprise infrared ray, pyroelectricity OR circuit induction installation and switching valve execution architecture; The input end of single-chip processor i/o is connected with OR circuit receiving device mouth, 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.The OR circuit connection mode is that infrared detection circuit, pyroelectricity testing circuit mouth are connected with two diode cathodes respectively, pass through resistance eutral grounding after two diode cathode parallel connections, even the door form, its negative pole parallel connected end is for having double monitoring signal monitoring end.
The invention solves its beneficial effect: the invention is by the human-induced signal of infrared ray, pyroelectricity OR circuit 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.
