Abstract: As a vertical transportation tool for high-rise buildings, the role of the elevator is prominent, and the safety of the elevator is particularly important, however, with the rising number of high-rise buildings, elevator operation failures are increasing. Taking the elevator system using a programmable controller as the research object, this paper started from the elevator control method and mechanical structure, analyzed various operating states of the elevator accident, and explored the cause of the accident. At the same time, an innovative design scheme of the elevator stopping and mechanical system was proposed by simulating the safety accident of the elevator speed governor, adjusting the actual elevator structure and operating state.

目前,电梯的主要控制形式分为两种:传统继电器控制系统和现代电梯控制系统。其中,传统电梯控制形式以继电器控制系统最为常见,而现代电梯控制形式主要由两种系统决定,一是基于可编程控制器(Programmable Logic Controller,PLC)的电梯控制系统,二是微型计算机电梯控制系统。以基于可编程控制器的电梯系统为研究对象,本文从电梯控制方式和机械结构出发,分析电梯事故的各种运行状态,然后明确事故原因,同时模拟电梯限速器安全事故,调整电梯结构和实际运行状态,提出创新性的电梯制停机械系统设计方案。
传统的继电器电梯控制系统已经不能达到现代电梯的使用标准,其主要存在故障检查烦琐、检测工作量大、继电器设备容易损坏、设备可靠性和安全性比可编程控制器电梯系统低等缺陷。近年来,可编程控制器电梯系统逐渐广泛应用于电梯控制领域,但该系统不是完美的,也存在相应问题。……
