| 摘 要： | 矿井通风实验通常需要大面积的实验巷道和多人协作一起完成，费时费力。由于仪器精度等诸多问题，教学演示往往达不到预期效果。根据相似原理，使用PVC管搭建小体积矿井模型，利用压差传感器、风速传感器以及风门执行器进行了矿井通风的模拟与实验。上位机软件采用Visual Basic程序编写，通过CAN-BUS总线采集压差和风速的模拟信号，并输出风门角度控制模拟信号进行实际监测与控制。该系统具有成本低、体积小、操作简单直观、功能多等特点。 |

| Abstract： | Mine ventilation experiment usually requires a large area of experimental tunnels and cooperation of many people, which is time-consuming and laborious. The teaching demonstration often can not achieve expected effect because of many problems such as instrument precision. According to similarity principle, PVC pipes were used to construct small mine model. Pressure difference sensors, wind speed sensors and air-door actuators were used to perform simulation and experiment of the mine ventilation. The host computer software was compiled with Visual Basic program. The CAN-BUS acquired simulation signals of pressure difference and wind speed and outputted air-door angle control simulation signals to perform practical monitoring and controlling. The system has advantages of low cost, small volume, simple and intuitionistic operation, and many functions. |
