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.

電梯在當代家居生活中承擔著人流和物流運送的任務。自20世紀80年代以來,隨著經濟建設的快速發(fā)展,中國對電梯的需求量呈快速上升趨勢,目前,中國已成為世界上最大的電梯市場,電梯運行能效指標變得及其重要[1-6]。
在實際的電梯系統(tǒng)運行中,經常遇到電梯內部裝有的貨物已經占滿電梯空間,但在外部請求控制下,若質量未達到閾值,電梯還會開門的情況。該現(xiàn)象使電梯的能效指標下降,不利于節(jié)能[7]。本文針對這一問題,對電梯控制系統(tǒng)進行了優(yōu)化設計。系統(tǒng)下位機利用光敏傳感器模塊對電梯內部占用空間進行測量。通過單片機采集光傳感器模塊光線被遮擋后輸出的低電平個數(shù),計算空間占有率,當達到電梯飽和的體積占有率閾值時,電梯控制系統(tǒng)不再受到外界請求信號進行開門控制,解決了傳統(tǒng)電梯控制系統(tǒng)因無法判定電梯內部空間被占滿而產生的門控無效打開問題。
