Study on the Internet of things system for dust migration control on excavation surface

In view of the current situation of serious dust over limit and low intelligence level in the integrated excavation face, combined with the smart control device of wind flow developed in the laboratory, an intelligent control system of wind flow in the integrated excavation face is developed based on the Internet of things technology. This paper presents the realization method of the system hardware and the development process of the software. The system collects the sensor signals and remotely transmits data from the intelligent control device for the wind speed, gas, dust and wind current at the fully mechanized working face, and the remote transmission of data. The device performs automatic control to achieve real-time regulation of dust movement.Finally, the software and hardware system is applied to the intelligent adjustment test platform of local ventilation equipment in coal mine for testing. The test results show that the system runs smoothly, the data is accurate and the operation is simple.
