Elevator serial push-button based on serial communication protocol

Abstract

The invention relates to an elevator serial button based on the serial communication protocol, which includes an input module, a button module, an MCU module, an indicator, an output module, a power module and a communication module; the button module includes 1 to N buttons; N can be a positive integer from 2 to 64; the signal line (SCLK) of each button is connected with that of a main board; the output of the main board is connected with the input of a first button; the output of the first button is connected with the input of the second button, and so on; the output of the last button is connected with the input of the main board; both ends of the main board power are subsequently connected with the first button to the last button with the help of connection of two adjacent buttons; the invention has the advantages of main board resource saving, convenience in connection, guide wire saving, and random allocation of the button functions.

Description

technical field [0001] The invention relates to an elevator, in particular to the button connection relationship in the elevator. Background technique [0002] With the rapid development of my country's social economy, a large number of high-rise buildings have emerged, and the role played by elevators in people's lives has become more and more important. At the same time, elevator installation companies have put forward higher and higher requirements for the convenience of component installation, and the installation of command buttons has become a component product that cannot be ignored. [0003] At present, the command buttons in the elevator all adopt the traditional point-to-point connection method, which requires the car board to have many button interfaces, and even an external expansion board is required, which is inconvenient for wiring. Simultaneously, the button connection wires in the car are very many and messy, especially in the car of high floors, this pheno...

Problems solved by technology

[0003] At present, the command buttons in the elevator adopt the traditional point-to-point connection method, which requires a lot of button interfaces on the car board, and even an external expansion board, which is inconvenient for wiring.

At the same time, there are many and messy button connection wires in the car, especially in the car on high floors.

Complicated inspection and replacement of wiring when button failure requires repair
