Research And Design Of Monitor System For Ventilator In Coal Mine

Ventilator is a core device of the mine ventilation system for providing necessary impetus to the airflow and it's essential to keep main fan work normally. Therefore, monitoring the functional mode of main fun is an important way to understand the entire ventilation system and a kind of assurance to normal production for mine.The system uses a high reliability STC89C52 microcontroller as its core to design and implement real-time monitoring of the fan parameters and real-time processing. What's more, the system achieved long-range monitoring by connecting with upper computer network in central control room. The system has solved some issues exist in previous system such as: simple system structure, low accuracy of some key parameters (such as the fan flow), defective contents of monitoring and no information systems integration with the control center.This system greatly improved the efficiency of the fan monitoring and saved a lot of manpower and resources. At the same time, the system has improved the automatic management level on the main ventilation equipment, ensure the main ventilation equipment work effectively, propose reliable scientific basis for equipment management and maintenance.
