摘要
对同步测频法进行了详尽的误差分析并由此对该方法做了改进。以此为据,指出了在实际系统中应用此方法的要点和如何合理选择测量参数。同时提出了一种在单片机系统中实现这种测量的具体方法,并举出了一个应用于油井压力计的实例作为说明。
The elaborate error analysis of synchronous frequency measurement method is presented and some amelioration of the method based on the analysis is proposed.From this,the article proposes how to apply the method and choose its parameters in practi-cal systems.A practical method to accomplish the measurement in MCU systems is also proposed.An example of high precision frequency measurement in a pressure gauge il-lustrates the proposed concepts.
