摘要
计数器基于凌阳SPCE061A微处理器设计,对高频信号采用测频法,提高精度,对低频信号采用测周法,可最大限度减小误差。能够接收函数信号发生器产生的信号,实现周期测量和时间间隔测量。可记忆10个测量的历史数据,实现语音报数功能且能够显示温度等多种功能。本系统经实验调试,较好地实现了预定的功能,由于采用了凌阳单片机控制,系统可靠性和性价比较高。
The designed counter adopts Sunplus SPCE061A MCU, uses frequency measurement for high frequency signal to improve the accuracy, and uses cycle measurement for low frequency signal to reduce error maximumly. It can receive the signal generated by the function generator to realize interval measurement and cycle measurement. It also can recall ten latest data, speak it out and display the temperature and amplitude on the LCD module. The experiment shows that the system has better predetermined function, reliability and cost-effective.
