摘要:针对传统电梯控制系统存在的质量虽未达到电梯系统的阈值设定,但电梯内部空间被占满,导致依据质量指标判定,响应外部请求而使门控进行无效打开的问题,对电梯控制系统进行优化设计。系统釆用STM32单片机作为主控芯片,利用光敏传感器进行电梯空间占用率的感知。采用LabVIEW搭建上位机,对电梯运行数据实时监测。测试结果表明,该系统能够准确检测电梯空间占用率,并根据空间占用率进行电梯运行控制,解决了因无法判定电梯内部空间占有率而产生的门控无效打开问题,极大节约了电力资源,节省了乘客搭乘时间,提高了电梯的运行能效。

Abstract:In view of the fact that the quality of the elevator system does not reach the threshold of the elevator system, but the internal space of the elevator is occupied, resulting in responding to external control and making the door control invalid open only according to the quality index. The elevator control system is optimizedand designed. The system uses STM32 microprocessor as the main control chip, and the optical sensor is designed by using photosensitive resistor to perceive the space occupancy of elevator,and the elevator space occupancy is sensed by using LabVIEW to build the upper computer to monitor the elevator operation data in real time. The test results show that the system can accurately detect the elevator space occupancy rate and control the elevator operation according to the space occupancy rate, which solves the problem of invalid opening of the door control caused by the inability to determine the space occupancy rate of the elevator.

电梯在当代家居生活中承担着人流和物流运送的任务。自20世纪80年代以来,随着经济建设的快速发展,中国对电梯的需求量呈快速上升趋势,目前,中国已成为世界上最大的电梯市场,电梯运行能效指标变得及其重要[1-6]。
在实际的电梯系统运行中,经常遇到电梯内部装有的货物已经占满电梯空间,但在外部请求控制下,若质量未达到阈值,电梯还会开门的情况。该现象使电梯的能效指标下降,不利于节能[7]。本文针对这一问题,对电梯控制系统进行了优化设计。系统下位机利用光敏传感器模块对电梯内部占用空间进行测量。通过单片机采集光传感器模块光线被遮挡后输出的低电平个数,计算空间占有率,当达到电梯饱和的体积占有率阈值时,电梯控制系统不再受到外界请求信号进行开门控制,解决了传统电梯控制系统因无法判定电梯内部空间被占满而产生的门控无效打开问题。
