Control principle of intelligent IC card ladder diagram control system

With the increase of building service time, there will be more and more users, and the number of natural salesmen and decorators will also increase. In order to avoid unnecessary disturbance to owners and residents, strengthen the safety of buildings, improve the intelligent management of properties and support environmental protection measures (saving electricity), elevator control management is particularly important.

Control mode 1: Control the elevator call button outside the elevator. This control method is to install a card reader outside the elevator, that is, at the door of the elevator hall, and connect with the elevator controller. Only when the user swipes the card effectively can the elevator call button be activated, the floor button in the elevator bridge box be activated and the user can use the elevator. The card reader is installed in the elevator hall on the first floor of the underground garage or in the elevator hall on the first floor. This control method is simple and will not limit the floors that users can reach.

Control mode 2: the floor button is controlled in the elevator bridge box, and the inductive card reader, card reader module and function expansion module are installed in the elevator box to form the elevator control unit. After the cardholder reads the card in the elevator, the system allows the cardholder to reach the authorized floor according to the preset settings. If the cardholder operates the unauthorized floor button, the elevator will not respond. Non-cardholders cannot operate the elevator.
