The invention relates to an elevator running direction judgment method, system and equipment. The method comprises the following steps that air pressure data and running speed data of an elevator car are obtained; the time delay air pressure difference delta bpt at each moment is calculated based on the air pressure data, the time delay air pressure difference delta bpt represents the air pressure difference value between the air pressure value at the current moment and the air pressure value at the previous moment, the trend transformation condition of the air pressure of the lift car is obtained according to the time delay air pressure difference delta bpt, and the air pressure of the lift car is calculated according to the obtained trend transformation condition of the air pressure of the lift car. And judging the running direction trend when the lift car is started to run, and judging the running direction of the lift car in combination with the running speed data vrun. The system and the equipment are used for executing the method. The elevator running direction is judged by combining the air pressure data and the speed data of the elevator car, the accuracy of the judgment result can be effectively improved, interference of external factors on the judgment result can be reduced, and the method has the advantage of being high in error-tolerant rate.
本公开涉及一种电梯运行方向判断方法、系统及设备,方法包括以下步骤:获取电梯轿厢的气压数据和运行速度数据;基于气压数据计算每个时刻的时延气压差Δbpt,时延气压差Δbpt表示当前时刻的气压值与前一时刻的气压值的气压差值,根据时延气压差Δbpt获得轿厢气压的趋势变换情况,根据所得轿厢气压的趋势变换情况,判断轿厢启动运行时的运行方向趋势,并结合运行速度数据vrun,判断轿厢的运行方向。系统和设备用于执行上述方法。本公开结合轿厢的气压数据和速度数据来判断电梯运行方向,可有效提高判断结果的准确性,可降低外部因素对判断结果的干扰,并具有容错率高的优点。
