## Abstract

An elevator monitor as disclosed in the present utility model includes an upper cover and a bottom case, with the upper cover fixed to the opening position of the bottom case and a control panel provided in the inner space of the bottom case. The control panel includes a PCB board, a floor interpretation processor, an elevating speed recording and analyzing processor, an AV line inlet, a data line inlet, an AV line outlet, a data line outlet, a control switch, an LED indicator and a buzzer. The present utility model relates to an elevator monitor, which is of a structure being able to detect the stability of the elevator in seconds and prevent the phenomenon of abnormal drop. When the car of the elevator is caught in the hoistway, it will be convenient for workers to find the elevator in time for maintenance and rescue, thus improving safety, effect of use and practicality. Furthermore, the camera can detect whether the elevator door is blocked and monitor whether the elevator door can be closed.

## Claims

### Claim 1

An elevator monitor, comprising an upper cover and a bottom case, the upper cover being fixed to the opening position of the bottom case and a control panel provided in the inner space of the bottom case, the control panel comprising a PCB board, a floor interpretation processor, an elevating speed recording and analyzing processor, an AV line inlet, a data line inlet, an AV line outlet, a data line outlet, a control switch, an LED indicator and a buzzer, with the signal received by the data line inlet input to the elevating speed recording and analyzing processor and processed by the elevating speed recording and analyzing processor before being input to the data line outlet, the buzzer, and the LED indicator, and the signal received by the AV line inlet being input to the floor interpretation processor and being processed by the floor interpretation processor before being input to the AV line outlet.

### Claim 2 (depends on 1)
