The invention relates to the field of elevator door fault monitoring, in particular to an elevator door fault monitoring system and method, and the method comprises the following steps: video collection, video storage, image processing, center coordinate calculation, speed calculation, elevator door motion state judgment and motion array extraction, feature value extraction, fault judgment and fault early warning. Through video data collected by a camera and an image processing technology, the states of the elevator landing door and the elevator car door can be monitored in real time, and the fault conditions of abnormal opening and closing, clamping or damage and the like can be found in time; by calculating the center distance between the left marker and the right marker in the opening and closing process of the elevator door and combining establishment of a speed array and extraction of characteristic values, the motion state of the elevator door can be judged more comprehensively and accurately, and therefore potential faults are recognized; and when it is detected that the elevator door is abnormal or breaks down, the server can send out fault early warning information in real time, and the timely response capacity to potential risks is improved.

    本发明涉及电梯门故障监测领域,尤其涉及一种电梯门故障监测系统和方法,包括以下步骤:视频采集、视频存储、图像处理、中心坐标计算、速度计算、电梯门运动状态判断及运动数组提取、特征值提取、故障判断和故障预警,通过摄像头采集的视频数据和图像处理技术,能够实时监测电梯层门和轿厢门的状态,及时发现非正常开合、卡住或损坏等故障情况;通过计算电梯门开关过程中左右标志物的中心距离,结合速度数组的建立和特征值的提取,能够更全面、准确地判断电梯门的运动状态,从而识别潜在故障;在检测到电梯门存在异常或故障时,服务器能够实时发出故障预警信息,提高了对潜在风险的及时响应能力。
