本发明涉及一种用于电梯轿厢绝对位置检测的解码器及解码方法,属于电梯控制技术领域,其中解码器包括传感器模块、微处理器模块、通信模块和存储模块,其中传感器模块包括多个并列设置的霍尔传感器,并且各个霍尔传感器之间的距离与传感器模块同一时间下读取的对应磁极间距相等;微处理器模块并行读取各个霍尔传感器的输出值,根据输出值利用绝对位置解码算法解算出解码器的当前绝对位置信息,并将当前绝对位置信息通过通信协议发送至电梯控制系统。本发明是一种针对利用磁极编码的磁条专用的解码器及解码方法,具有解码速度快、精度高、成本低的优点,适用于各种类型的电梯的绝对位置检测。
The invention relates to a decoder and a decoding method for detecting the absolute position of an elevator car, and belongs to the technical field of elevator control. The decoder comprises a sensor module, a microprocessor module, a communication module and a storage module, the distance between the Hall sensors is equal to the corresponding magnetic pole distance read by the sensor module at the same time; and the microprocessor module reads the output values of the Hall sensors in parallel, calculates the current absolute position information of the decoder by using an absolute position decoding algorithm according to the output values, and sends the current absolute position information to an elevator control system through a communication protocol. The decoder and the decoding method special for the magnetic strip coded by the magnetic poles have the advantages of being high in decoding speed, high in precision and low in cost, and are suitable for absolute position detection of various types of elevators.
