The invention belongs to the field of elevator equipment, and particularly relates to an elevator floor self-adaptive detection method. The method includes the steps that the air pressure value of the bottommost layer of an elevator is set as the maximum air pressure value, and the air pressure value of the topmost layer of the elevator is set as the minimum air pressure value; collecting a current air pressure value through an air pressure temperature sensor, and calculating a relative height difference according to the current air pressure value and the maximum atmospheric pressure value; determining an elevator floor corresponding to the current air pressure value according to a preset mapping floor table and the relative height difference; when the elevator runs to the bottommost layer or the topmost layer, the maximum air pressure value and the minimum air pressure value are updated through a restraining minimum and maximum value algorithm; air pressure self-correction is carried out by adopting a contained minimum and maximum value algorithm, the interference of external factors such as temperature is eliminated, the influence of the change of atmospheric pressure on the initial calibration of the system floor is filtered, and the floor detection accuracy is improved.
本发明属于电梯设备领域,具体涉及一种电梯楼层自适应检测方法;包括:设置电梯最底层的气压值为最大气压值,电梯最顶层的气压值为最小气压值;通过气压温度传感器采集当前气压值,根据当前气压值和最大气压值计算相对高度差;根据预设映射楼层表和相对高度差,确定当前气压值所对应的电梯楼层;当电梯运行到最底层或最顶层时,采用牵制最小最大值算法更新最大气压值和最小气压值;本发明采用牵制最小最大值算法进行气压自校正,排除温度等外界因素的干扰,滤除了因大气压的变化对系统楼层初始定标的影响,提升楼层检测准确度。
