The invention discloses a device for recognizing the stopping floor and speed of an elevator car. The device comprises a sensing device, a sensor, a signal processing module, a memory, a signal comparator and a transmission module, wherein the sensing device is arranged on an elevator guide device in an elevator system; and the sensor, the signal processing module, the memory, the signal comparator and the transmission module, which can sense the sensing device, are arranged on the elevator car. By means of the device, the floor where the elevator car stops and the running speed can be accurately recognized, real-time control monitoring is provided for a control room, passengers can know the elevator situation in time, and compared with the prior art, a speed feedback encoder of a frequency converter can be omitted, the phenomenon that speed measurement is inaccurate due to sliding of a steel wire rope is avoided, and meanwhile, a leveling switch in a hoistway can be omitted, installation is easy, convenient and fast, and measuring precision is high.
本发明公开了一种识别电梯轿厢停靠楼层和速度的装置,包括设置在电梯系统中的电梯导向装置上的被感应装置;设置在电梯轿厢上能够感应所述被感应装置的感应器、信号处理模块、存储器、信号比较器、传输模块。通过本发明的装置,能够准确识别出电梯轿厢停靠的楼层以及运行的速度,给予控制室实时控制监控和乘客及时了解电梯情况,相对于现有技术来说,可以节省掉变频器的速度反馈编码器,不会出现钢丝绳滑移导致测速不准的现象,同时可以节省掉井道内的平层开关,安装简便快捷。测量精度高。
