The utility model content
Therefore, stop and cause between electric energy and waste of time and inscribe at automatic vertical lift (especially public elevator) sky.The utility model is by installing the infrared monitoring parts additional on existing operation control system.Each floor is carried out the human body infrared monitoring.When the user of a certain floor presses elevator button, and abandon when leaving, infrared acquisition is after no human body infrared signal, and the utility model is by being connected with automatic control circuit, and the no user's signal of transmission, the halt instruction of this floor of indication operation control yarn system cancellation.Stop problem thereby stop sky, improve the elevator operating efficiency.
The technical solution of the utility model is:
A kind of nobody does not stop the lift circuit control system of layer, comprises the circuit of the position sensing circuit, switch gate control circuit, control panel key circuit, display driver circuit and the car electric machine control part that are connected in the PLC controller.Wherein, also be connected to infrared sensing circuit on the described PLC controller.
Further, described infrared sensing circuit comprises series connected successively infrared probe, amplifying circuit and comparison output circuit, and the power circuit that is connected in above-mentioned each module.
Further, described infrared probe is arranged on the elevator control panel of floor.
Further again, described infrared probe is arranged between the display space and key zone on the elevator control panel.
Further, the circuit of described car electric machine control part comprises:
The D/A change-over circuit, input is connected in described PLC controller, start-up circuit, output and is connected in the motor variable-frequency speed-regulating control circuit, and output output is connected in fault diagnosis circuit;
The motor variable-frequency speed-regulating control circuit, input is connected in described D/A change-over circuit, and output is connected in car motor and waveform sampling circuit;
The waveform sampling circuit, input is connected in described motor variable-frequency speed-regulating control circuit, and output is connected in the A/D change-over circuit;
