Circuit capable of linkingelevator by door opening based on card swiping machine and implementation method for circuit

Abstract

The invention discloses a circuit capableof linkingan elevator by door opening based on a card swiping machine and an implementation method for the circuit. The circuit consists of a doorway entrance machine, a relay, an elevator calling button, a door lock, a door opening button, a triode, a resistor and a direct-current power supply, wherein a positive electrode of the direct-current power supply is connected to a DOOR+ end of a doorway entrance machine output switch, and an emitter electrode of the triode separately; a DOOR- end of the doorway entrance machine output switchis separately connected to one end of the door opening button, a base electrode of the triode and one end of the resistor; the other end of the door opening button is connected to a positive electrode of the door lock; a collector electrode of the triode is connected to one end of the coil of the relay J; a normally-open contact of the relay is connected to the elevator calling button in parallel; and a negative electrode of the direct-current power supply is connected to a negative electrode of the door lock, the other end of the coil of the relay and the other end of the resistor. The implementation method is that the relay is not energized when the door is locked, and is energized when a card swipes, and a dry contact signal is output to the elevator calling button to call the elevator, so that the elevator calling function is realized. The circuit is low in cost, and is energy-saving.

Description

technical field [0001] The invention belongs to the field of intelligent building engineering, and relates to a circuit that allows the owner to call an elevator while swiping a card to open the door at the entrance and exit of the first floor of the building, thereby reducing the waiting time for the elevator. . 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 elevator lobby on the first floor and the basement of each floor, that is, when the owner enter...

AI Technical Summary

Problems solved by technology

Everyone knows: the closing time of the door is much longer than the opening time, and the circuit record of the entrance and exit door machine with the application number 201420674875.5 swiping the card to open the door and call the elevator: the relay coil is energized during the door closing time, so it cannot save power
