The invention discloses an equipment abrasion state wireless monitoring device based on the internet of things. The equipment abrasion state wireless monitoring device based on the internet of things comprises a wireless monitoring and transmitting module and a wireless monitoring system module. The wireless monitoring and transmitting module comprises a sensor, a signal amplifier, an analog-digital converter, a microprocessor and a wireless transmitter, wherein the sensor, the signal amplifier, the analog-digital converter, the microprocessor and the wireless transmitter are sequentially connected; the wireless monitoring system module comprises a wireless receiver, a level translator and a PC, wherein the wireless receiver, the level translator and the PC are sequentially connected. According to the equipment abrasion state wireless monitoring device based on the internet of things, a wheel bushing of a traction wheel rope groove reaching to an abrasion critical value is diagnosed in advance through the detection of contact fatigue contacts of the surface of the wheel bushing of the traction wheel rope groove, abrasive wear state and oxidative wear degree, the collected abrasion state information is transmitted to an enterprise management platform or relevant management personnel in a wireless transmission mode, working personnel do not need to descend to a well to detect and eliminate potential safety hazards any more, early warning of abrasion situations of the wheel bushing of the mine traction wheel rope groove is accurately and intelligently carried out in real time, and accordingly safety coefficient of the mine traction wheel is greatly increased in the operation process.
