摘要
针对中国金属矿山斜井人车的测速问题,主要介绍了DSP芯片TMS320VC5402的特性。利用现代谱估计的算法,在DSP芯片中对检测车辆雷达运动产生的多普勒频率进行频谱分析。文中给出系统硬件、软件设计结构和原理图,改善了原有光电测速精度,提高了系统工作稳定性和可靠性。整个装置体积小、质量轻,可实现便携式测量。
This paper mainly introduces the characteristics of the DSP chip TMS320VC5402 in speed measurement of claw passenger trucks. With modern spectral estimation algorithm, spectrum analysis on Doppler frequency caused by vehicles radar movement is carried out in DSP chip. This paper presents the hardware, software design and structure diagram of the DSP chip which improves the system stability and reliability. The whole device which is of small size and light weight can realize portable measurement.
