This paper proposes a project of software and hardware bases on fixed gate-time, high-speed and continuous measuring method, according to high-speed dynamic frequency object with certain renewal rate. Combined with the abundant hardware resources of C8051F series microcontroller, key problems of hardware realization of frequency measuring module is solved to realize the high-speed and high-precision frequency measurement. Problems of mass data transmission caused by multi-channel, high-speed frequency measuring are studied. A kind of multi-channel,high-speed, high-precision frequency measurement system which could storage and analysis data is designed. The system reduces the cost of development and technical threshold, achieving precision of measurement.
