The invention discloses an elevator door opening and closing abnormity detection method based on millimeter waves. The elevator door opening and closing abnormity detection method comprises the following steps that firstly, elevator door opening and closing detection based on the millimeter waves is conducted; step 2, detecting people in the elevator based on millimeter waves; 3, when the elevator door is opened, the distance between the person in the elevator and the elevator door is smaller than a second distance threshold value, and the movement speed of the person is smaller than a speed threshold value, it is judged that the elevator door is in a man-made abnormal state, and elevator door closing is blocked; and fourthly, when the elevator door is closed and people exist in the elevator, it is judged that the elevator is in the people trapping state. The system is simple in structure and reasonable in design, the elevator door opening and closing state is detected through the first millimeter wave detection module, the personnel information in the elevator is detected through the second millimeter wave detection module, and door operation is conducted on the elevator door opening and closing state, the personnel information in the elevator and the elevator detection state; and whether the elevator door is blocked manually and abnormally and whether people are trapped in the elevator are judged, and the detection result is accurate.

    本发明公开了一种基于毫米波的电梯开关门异常检测方法,包括以下步骤:步骤一、基于毫米波的电梯开关门检测;步骤二、基于毫米波的电梯内人员检测;步骤三、当电梯门打开、电梯内人员距离电梯门的距离小于第二距离阈值、人员运动速度小于速度阈值时,则判断电梯门处于人为异常阻挡电梯关门;步骤四、当电梯门关闭、电梯内有人时,则判断电梯处于困人状态。本发明结构简单、设计合理,通过第一毫米波检测模块检测电梯开关门状态,通过第二毫米波检测模块检测电梯内的人员信息,对电梯开关门状态、电梯内的人员信息以及电梯检测状态进行与门运算,判断电梯是否处于人为异常阻挡电梯关门和电梯是否出现困人现象,检测结果精准。
