摘要
速度和加速度是衡量矿用运输设备的重要安全技术指标。基于多普勒测速原理、DSP数字信号处理技术以及ARM嵌入式技术,采用改进的伯格算法和QWT软件技术,研制出车载非接触式测速装置,实现了矿用运输设备运行速度的实时、准确测量。该测速装置的测速范围为10 m/s,速度测量精度为±0.1 m/s,加速度测量精度为0.05 m/s^(2)。
The speed and acceleration of vehicles are important safety technical indicators to measure the mining transportation equipment.Based on the principle of Doppler speed measurement,DSP digital signal processing technology and ARM embedded technology,an on-board non-contact speed measurement device was developed by adopting the improved Burg algorithm and QWT software technology,which can effectively ensure the real-time and accurate measurement of transportation equipment.The speed measuring range of the device is 10 m/s,the accuracy is±0.1 m/s,and the acceleration measuring accuracy is 0.05 m/s^(2).
