Circuit for realizing door open by swiping a card and elevator call of exit/entrance doorphone and realizing method of circuit

Abstract

The invention discloses a circuit for realizing door open by swiping a card and elevator call of an exit / entrance doorphone and a realizing method of the circuit. The circuit is composed of an exit / entrance doorphone, a single-circuit normally-closed relay J, an elevator call button, a door lock, a door open button of the door lock and a direct-current power supply. The circuit is characterized in that the anode of the direct-current power supply is connected with the DOOR+ end of an output switch of the exit / entrance doorphone, the DOOR- end of the output switch of the exit / entrance doorphone is respectively connected with one end of a coil of the relay J and one end of the door open button, the other end of the door open button is connected with the anode of the door lock, a normally-closed contact of the relay J is spliced with the elevator call button, and the cathode of the direct-current power supply is connected with the cathode of the door lock and the other end of the coil of the relay J. The method is characterized in that the one circuit of power supply is adopted, and the relay adopts a single-circuit normally-closed contact, so that the exit / entrance doorphone achieves the function of calling an elevator while opening a door by swiping a card. The circuit also has the advantages of low cost, energy saving and reliability.

Description

technical field [0001] The invention belongs to the field of intelligent building engineering, and relates to a circuit for enabling the owner to call an elevator 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. Implementation. 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 ...

AI Technical Summary

Problems solved by technology

However, at present, the door phone calls the elevator and usually sends the electrical signal to the elevator machine room. Generally, the call to the elevator is on the first floor, but the elevator machine room is on the top floor. Therefore, this solution has long wiring, complicated construction, and signal attenuation. It is also not conducive to later maintenance

At the same time, there is also a record of the circuit of opening the door and calling the elevator by swiping the card of the entrance and exit machine with the application number of 201420674875.5: In order to overcome the problems and shortcomings of the existing schemes such as long wiring, complicated construction, and signal attenuation, it is proposed to use the signal output by directly swiping the card of the entrance and exit door machine (Generally, the signal output by the door machine at the entrance and exit is a dry contact signal after swiping the card) is divided into two circuits by a double relay, and one signal is sent to the elevator call button on the current floor (generally, the signal collected by the elevator call button is a dry contact signal) to realize calling the elevator. function, the other signal is sent to the door lock to realize unlocking

However, in order to solve the problems existing in the prior art, the present invention adds a set of DC power supply to the technical solution, and the relay adopts dual output, which has the defects of high cost and no energy saving
