Circuit based on linkage among access admission of card swiping machine with elevator calling and lighting and realizing method of same

Abstract

The invention discloses a circuit based on the linkage among the access admission of a card swiping machine with elevator calling and lighting and a realizing method of the same. The circuit comprisesan output linkage signal module and a receipt linkage signal control module, wherein the input of the receipt linkage signal control module is connected with the output of the output linkage signal module through an outer connecting wire; the output linkage signal module comprises an access control machine, a door lock, a door-open button, a switching tube Q1, a resistor R1, diodes D1, D2 and D3and a direct current power supply; one end of the door-open button is connected to the positive pole of the direct current power supply, the other end of the door-open button is connected to the positive pole of the door lock, the negative pole of the door lock is connected to the DOOR+ end of the output switch of the access control machine, and the DOOR- end of the output switch of the access control machine is connected to the negative pole of the direct current power supply; one end of the resistor R1 is connected to the positive pole of the direct current power supply, the other end of theresistor R1 is connected to the anodes of the diodes D1 and D3 in parallel; the cathode of the diode D3 is connected to the DOOR+ end of the output switch of the access control machine; the cathode of the diode D1 is connected to the anode of the diode D2; the cathode of the diode D2 is connected to the control end of the switching tube Q1; the positive pole of the direct current power supply isconnected to the positive pole of the receipt linkage signal control module through an outer connecting wire; the high potential end of the switching tube Q1 is connected to the negative pole of the receipt linkage signal control module through an outer connecting wire; the low potential end of the switching tube Q1 is connected to the negative pole of the direct current power supply; the D3 withthe cathode being connected to the DOOR+ end of the output switch of the access control machine is placed in the circuit; and the anode of the D3 is connected to the anode of the D1. The realizing method is characterized in that when the door is opened by swiping a card through the card swiping machine and the elevator on the same floor is called at night, a sound is produced from a close distanceto enable the lighting lamp in the elevator hall to be turned on by a sound-light controlled switch, and that a sound is produced on purpose from a remote distance to enable the lighting lamp in theelevator hall to be turned on is reduced.

Description

technical field [0001] The invention belongs to the field of intelligent building engineering, and in particular relates to a circuit and a realization method for enabling an owner to call an elevator and illuminate while swiping a card to open the door at the entrance and exit of the building on the first floor, thereby reducing the waiting time for the elevator and turning on the lighting in advance. Background technique [0002] With the improvement of urban people's living standards and the acceleration of the pace of life, the demand for life is not only material satisfaction, but the comfort and convenience of humanized experience. In order to better reflect the humanized design, in many high-end buildings, the video intercom system has been improved, and the function of calling the elevator by the door station has been added. The specific implementation of this function is to add the function of calling the elevator by swiping the card to the door machine of the eleva...

Problems solved by technology

It overcomes the problems and shortcomings of the original scheme, such as long wiring, complicated construction, and signal attenuation

It seems to be a perfect design, but there is a fatal flaw: when the door is opened by swiping the card at the entrance and exit door, the output switch of the entrance and exit door is disconnected, the transistor Q is saturated, the relay J is closed, and the normally open contact generates a connection signal to the elevator call The button calls the elevator to realize the elevator call function; but at this time, because the base of the triode Q is connected to the DOOR- terminal of the output switch of the entrance and exit door machine, the base current of the triode Q is not only the resistance of the base connected to the negative pole of the DC power supply in series R to limit, but the resistor R and the door lock connected in series with the door open button are connected in parallel to co
