煤矿井下便携式智能风速测量仪的设计

Design of the portable intelligent wind speed measuring instrument in coal mine

介绍了煤矿井下便携式微功耗风速测量仪的设计,使用内置矿用可充电3.2V 锂电池供电,本安型设计,与现有技术相比具有精确度高、数据处理功能强大、功耗小、成本低、质量轻等特点,现场使用时可以对井下各点风速进行实时测量,由风速可以高效准确地计算出风量,保障了矿井通风与生产安全。

The design of the portable micro-power wind speed measuring instrument for coal mine is introduced. Compared with the existing technique, this instrument is high accuracy, powerful data processing, low power consumption, low cost, light weight and other characteristics by using the 3.2V rechargeable lithhim battery power and intrinsic safety design. Using this instrument onsite, the parameters of wind speed can be measured in real-time, so the air volume can be accurately calculated, and then the mine ventilation and production safety are protected.
