The invention relates to the technical field of elevator detection, and discloses an elevator slip detection method. The method comprises the steps of controlling a car to run to a first preset position at a preset speed; emergently braking the car; calculating theoretical position information of the car; acquiring actual position information of the car; and judging the safety condition of an elevator system according to the theoretical position information and the actual position information. According to the method, the car of the elevator system to be detected is controlled to run at the preset speed, and the elevator system is emergently braked after the car runs to the first preset position; the actual position information of the car after emergency braking is detected, and the steel wire rope slip distance of an elevator is acquired according to the actual position information and the theoretical position information; and the steel wire rope slip distance is used as a fault diagnosis condition to judge whether the elevator has a safety problem or not, so that the accuracy of steel wire rope slip fault detection is greatly improved, false report or missing report of steel wire rope slip faults is avoided, and the operation safety of the elevator is improved.

    本发明涉及电梯检测技术领域,公开了一种电梯打滑检测方法,包括控制所述轿厢以预设速度运行至第一预设位置;使所述轿厢紧急制动;计算所述轿厢的理论位置信息;获取所述轿厢的实际位置信息;根据所述理论位置信息和所述实际位置信息判断所述电梯系统的安全情况。控制待测电梯系统的轿厢以预设速度运行,并在运行至第一预设位置后令该电梯系统紧急制动。通过检测在紧急制动后轿厢的实际位置信息,并根据实际位置信息与理论位置信息获取电梯的钢丝绳打滑距离。将钢丝绳打滑距离作为故障诊断条件,判断电梯是否存在安全问题,从而大幅提升对于钢丝绳打滑故障检测的准确性,避免误报或漏报钢丝绳打滑故障,提高电梯运行安全性。
