摘要
分析了利用单片机进行测频时测量原理、引起误差的原因,给出了提高频率测量精度方法,以及相应测量系统硬件、软件设计思想.在设计中测频计数闸门完全由硬件控制,测频精度高,硬件、软件实现较方便、灵活、可靠.
The principle of frequency measuring based on single chip computer and case of metrical error is analyzed in the paper. The methods for frequency measurement are introduced, and the idea about how to design the hardware and software of the frequency measurement system is presented. The gateway of frequency measuring is controlled by hardware rather then software, which makes frequency measuring highly precise, convenient, agile and reliable.
