一种基于RS485的电梯通讯方法

By improving the RS485 polling mechanism, the current floor and the next floor of the elevator are queried in real time, and call button commands are processed with priority. This solves the problem of elevator response delay in high-rise buildings and improves the safety and response speed of elevators.

AI Technical Summary

Technical Problem

The existing RS485 polling mechanism causes excessive delays in receiving operation commands from the elevator mainboard in high-rise buildings, posing a safety hazard and failing to meet the real-time requirements of elevator operation.

Method used

By improving the existing polling mechanism, the system queries the current floor in real time and prioritizes the processing of elevator call button commands to promptly open the door; it also queries the next floor in real time and prioritizes the processing of elevator call button commands to ensure the flexibility of interception in the same direction while the elevator is running at high speed.

Benefits of technology

It enables real-time response of elevators in high-rise buildings, avoids the risk of passengers being trapped in the doors, improves the success rate of interception during high-speed elevator operation, and reduces interception failures caused by communication delays.

Abstract

本发明公开了一种基于RS485的电梯通讯方法,包括步骤:采用RS485通讯协议对外呼显示板进行轮询,并获取电梯当前运行状态;若当前运行状态为停站状态,则对同楼层外呼显示板进行第一询问,若当前运行状态为运行状态,则对下一楼层外呼显示板进行第二询问;将第一询问获取的指令信息或者第二询问获取的指令信息作为最高优先级中断进行处理;通过对现有的轮询机制进行改善,对当前停站的楼层进行实时询问,并优先处理获取的呼梯按键指令,及时进行开门动作,避免客户被门夹;通过对下一楼层进行实时询问,并优先处理获取的呼梯按键指令,保证电梯高速运行中同向拦截电梯灵活,避免因为通讯延时造成拦截电梯失败。
