the abnormal analysis module receives that the inclination angle is in a first inclination threshold value interval, and judges that the inclination angle of the elevator is in a normal range;
the method comprises the steps that an abnormal analysis module receives an inclination angle in a second inclination threshold interval, judges that the inclination angle of an elevator is abnormal and generates a slight inclination abnormal signal, the abnormal analysis module transmits the slight inclination abnormal signal to a central processing module, the central processing module controls an image recording module to observe the placement condition of a person station or goods in the elevator, if the person or the goods are concentrated and gathered, the inclination angle of the elevator is judged to be in a normal range, the central processing module controls the image recording module in the elevator to carry out voice warning, a passenger in the elevator is reminded to carry out station adjustment, the goods are placed and adjusted, if the person or the goods are not gathered, the inclination angle of the elevator is judged to be in an abnormal range, the elevator can normally operate, the central processing module records the abnormal information, meanwhile, controls angle change information in 1h after information recording of an inclination monitoring module, if the inclination angle change is in the second inclination threshold interval, the central processing module sends a maintenance instruction, the maintenance instruction is loaded to a maintenance module, and the maintenance module receives the maintenance instruction to inform the maintenance personnel to carry out elevator maintenance.
The abnormal analysis module receives the inclination angle in a third inclination threshold interval, judges that the inclination angle of the elevator is abnormal and generates a serious inclination abnormal signal, the inclination angle is outside an abnormal range, the elevator can not normally operate, the abnormal analysis module transmits the serious inclination abnormal signal to the central processing module, the central processing module sends a maintenance instruction, the maintenance instruction is loaded to the maintenance module, and the maintenance module receives the maintenance instruction to inform maintenance personnel of carrying out elevator maintenance;
the image recording module comprises a voice playing unit, an input unit and a shooting unit, wherein the input unit is used for inputting image information and voice information in the elevator, the input image information and voice information are transmitted to the central processing module, the shooting unit receives a control instruction of the central processing module to observe the distribution information of passengers in the elevator, the phenomenon that the aggregation of the passengers is offset in angle occurs, and the central processing module controls the voice playing unit to broadcast information.
