The invention relates to a position identification device and a detection system for detecting the absolute position of an elevator car, belongs to the technical field of elevator equipment, and solves the problems of low precision, high environmental requirements, high cost and the like of the existing method for detecting the absolute position of the elevator car. The position identification device comprises magnetic strips installed in an elevator shaft in a segmented mode, an upper door area, an upper floor absolute coding area, a flat layer position induction area, a lower floor absolute coding area and a lower door area are sequentially distributed on the magnetic strips, and the identification recognition device reads sensing data of Hall sensors corresponding to all the areas of the magnetic strips. And outputting a corresponding signal to an elevator control system. According to the invention, the overall length of the magnetic strip is shortened, the cost is low, the absolute position detection of elevator cars in high-rise and super high-rise buildings is suitable, the service life is long, the detection precision is high, the induction distance is large, the anti-interference performance is strong, and the magnetic strip is not easily influenced by the ambient light intensity, the cleanliness and the magnetic field.

    本发明涉及一种电梯轿厢绝对位置检测用的位置标识装置及检测系统,属于电梯设备技术领域,解决了目前电梯轿厢绝对位置检测方法存在的精度不高、对环境要求高以及成本高等问题,该检测系统包括位置标识装置和标识识别装置,位置标识装置包括在电梯井道中分段安装的磁条,磁条上依次分布有上门区、上楼层绝对编码区、平层位置感应区、下楼层绝对编码区和下门区,标识识别装置读取磁条各个区域对应的霍尔传感器的传感数据,输出相应的信号至电梯控制系统。本发明缩短了磁条的整体长度,成本低,适合高层、超高层建筑物内电梯轿厢的绝对位置检测,使用寿命长,检测精度高,感应距离大,抗干扰性强,不易受环境光强、洁净度和磁场的影响。
