System and method for recognizing elevator buttons

Abstract

The invention discloses a system and method for recognizing elevator buttons. The system comprises an ID setting module and a button module. One end of the ID setting module is connected with the button module in an SPI communication mode, and the other end of the ID setting module is connected with an external device through a CAN bus. The button module comprises multiple buttons which are connected in the SPI communication mode. The method comprises the steps that the ID setting module is used for setting the ID numbers of the buttons in the button module; in use, after one button is pressed, the button sends the ID number data of the button to the ID setting module through SPI, the ID setting module displays the ID number data of the button and converts the ID number data to CAN data, and the CAN data is sent to a lift car communication board or an elevator main control panel; and the elevator main control panel recognizes the pressed button according to the received CAN data and sends out a corresponding instruction. By means of the system and method for recognizing the elevator buttons, the number of wires for connection of the elevator buttons can be reduced, the structure of the whole elevator system is simplified, and maintenance is facilitated.

Description

technical field [0001] The invention relates to a button recognition system and method, in particular to an elevator button recognition system and method, belonging to the technical field of elevator button recognition. Background technique [0002] In modern society, elevators have been widely used as auxiliary equipment for daily life, and are being installed at various construction sites with a rapid development momentum, especially in some high-end office buildings and residential areas. It can be said that elevators are inseparable from people's daily life. Become an indispensable means of transportation for transporting people and goods in multi-storey buildings. In the constituent parts of the elevator system, there must be buttons. [0003] At present, most of the command buttons in the elevator adopt the traditional point-to-point connection method, which requires the car communication board to have many button interfaces, and even an external expansion board is re...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the command buttons in the elevator adopt the traditional point-to-point connection method, which requires the car communication board to have many button interfaces, and even needs to be connected with an external expansion board. Each button needs to be wired separately, resulting in a large number of button lines in an elevator. And confusing, especially in the car on the high floor; when the button fails and needs to be repaired, it is more complicated to check and replace the wiring
