Elevator operation state monitoring system based on Internet of Things

The invention provides an elevator operation state monitoring system based on Internet of Things. The elevator operation state is monitored through a central processing device, a humidity sensor, a signal processing circuit, a rotary encoder, an infrared sensor, an image acquisition module, an image processing module, a comparison module, an alarm device, a display, a remote monitoring terminal and a power module. The humidity sensor is arranged at the top end of a lift car of an elevator and used for detecting humidity signals at the top of the elevator. The rotary encoder is arranged on a motor rotating shaft through a coupling and used for detecting the operation speed of the elevator. The infrared sensor is arranged inside the lift car of the elevator and used for detecting infrared rays transmitted by human bodies. The image acquisition module is arranged inside the lift car of the elevator and used for acquiring image information inside the lift car of the elevator. Workers can know the operation speed of the elevator, the humidity signals, infrared signals and the image information inside the lift car of the elevator in real time through the display and the remote monitoringterminal.
