矿井通风自动控制实验教学模型开发与应用

Mine ventilation experiments and teaching demonstrations usually required a large area of the experimental tunnel and collaboration with more than complete, time-consuming and laborious. Precision instruments because of many problems, often achieving the desired effects. According to similarity theory, the use of PVC pipe structures small mine model. The pressure sensors and wind speed sensors and throttle actuator model layout in the specified location. Prepared using Visual Basic PC software through the CAN-BUS Bus Acquisition pressure and wind speed analog signal and the output throttle angle control of the analog signal. The system has low-cost, small size, simple operation, intuitive, multi-functional characteristics. The film thesis on easy automatic control of mine ventilation model of experimental teaching the basic principles and detailed description of the experimental applications.
