Elevator calling system based on Wi-Fi (wireless fidelity) wireless network

Abstract

The invention relates to the technical field of an elevator. In order to solve the problems of high wiring cost and great wiring difficulty of a traditional elevator calling system, an appointment calling function is based on a wireless calling function, and the problem that the elevator waiting time of people with special tasks is too long is solved. The invention adopts the following technical scheme: in an elevator calling system based on a Wi-Fi (wireless fidelity) wireless network, an elevator inner selection plate in a car, an elevator outer calling plate of each floor and a core CPU (central processing unit) of a handheld wireless calling device are all connected with a Wi-Fi module through a serial port and used for receiving or sending data; the elevator inner selection plate and the elevator outer calling plates communicate with an elevator core controller in the Wi-Fi network; the handheld wireless calling device firstly needs to transfer a signal to the Internet through the Wi-Fi network, and a wireless AP (access point) / router receives the signal and transfers the signal to the elevator core controller; and the elevator core controller is connected with the wireless AP / router by a network cable. The system provided by the invention is mainly used for designing and manufacturing an elevator.

Description

technical field

[0001] The present invention relates to the technical field of elevators, the field of embedded technology, and the field of Wi-Fi wireless data transmission, in particular to an elevator calling system based on a Wi-Fi wireless network. Background technique

[0002] With the development of modern cities in China, a large number of residential quarters, commercial buildings, and company office buildings with high-rise buildings in the city have emerged. Elevators, as a vertical transportation tool, have become an indispensable transportation tool for people in the city. With the increase of building height, the wiring cost and wiring difficulty of the elevator call system have greatly increased.

[0003] The traditional elevator call system needs to connect the internal selection panel in the elevator car and the external call panel of each floor with the elevator core controller through wired methods such as RS422 / 485 or CAN bus, so that the elevator core co...
