频率计是数字电路中的一个典型应用，实际的硬件设计用到的器件较多，而且会产生比较大的延时，造成测量误差、可靠性差。传统的频率计一般是由分离元件搭接而成。随着单片机的大规模的应用，单片机在频率测量方面也越来越多的被使用。在本课题中使用的MCS-51这种低功耗,高性能的单片机，具有更好的稳定性，更快和更准确的运算精度，推动了工业生产，影响着人们的工作和学习。
本次设计就是要通过以MCS-51单片机为控制核心，实现对信号频率进行准确计数的设计。频率计装置由整形器、放大器、分频器、单片机系统，LED显示模块组成，实现对频率进行测试并在LED显示出来。
本次毕业设计是基于MCS-51单片机的频率计装置设计，设计sch电路原理图，并根据原理图完成硬件部分的制作，采用单片机应用系统编制C语言系统程序，最后通过综合调试，能实现所有要求的功能，完全满足本次毕业设计的要求。

Frequency of a digital circuit in a typical application, the actual hardware design of the devices used more and will have a big delay, caused by measurement error, poor reliability. The frequency of the traditional general is formed by discrete components lap. With large-scale application of the SCM, SCM in frequency measurement also be used more and more. In this issue of the use of MCS-51 This low-power, high-performance microcontroller, the stability is better, faster and more accurate calculation accuracy, and promote industrial production and affect people's work and study .
The design is to pass to MCS-51 for the control of microcontroller core, and the signal frequency accurate count of the design. Frequency of devices from plastic, amplifiers, crossover, SCM system, LED display modules, and the frequency of testing and LED display.
The graduation project is based on MCS-51 SCM frequency of device design, sch circuit design schematics, and under the principle
