The invention discloses an elevator running speed monitoring system and method. The system comprises a main control module, an identification module arranged in an elevator shaft and a brightness detection module arranged in an elevator car, wherein the identification module comprises optical identification piece, and the brightness states of the optical identification pieces are determined based on the floors where the optical identification pieces are located; the brightness detection module comprises a brightness detection unit which is used for detecting the brightness states of the optical identification pieces and generating detection signals; and the main control module is used for analyzing the detection signals and determining the number of floors corresponding to the optical identification pieces, determining the number of initial floors and the number of current floors corresponding to the two optical identification pieces before and after the elevator car runs, obtaining the running time of the elevator car passing through the front optical identification piece and the rear optical identification piece, and determining the running speed based on the running distance and the running time. According to the elevator running speed monitoring system and method, an independent speed detection mode is achieved in an elevator system through secondary development, the elevator running speed can still be effectively detected even if an elevator breaks down, and management and maintenance of the elevator system by a property management department are facilitated.
本发明公开了一种电梯运行速度监测系统和方法,该系统包括:主控模块、设置于电梯井内的标识模块、设置于电梯轿厢的光亮检测模块。其中,标识模块包括光标识件,光标识件的光亮状态基于其所处楼层确定。光亮检测模块包括:光亮检测单元,用于检测光标识件的光亮状态,生成检测信号。主控模块用于:解析检测信号并确定光标识件对应的楼层数;确定电梯轿厢运行经过前后两个光标识件对应的起始楼层数和当前楼层数;获取电梯轿厢经过前后两个光标识件的运行时间;基于运行距离与运行时间,确定运行速度。本发明通过二次开发在电梯系统中实现了独立的速度检测方式,即便在电梯故障时,仍能够有效检测电梯运行速度,便于物业对电梯系统的管理和维护。
