在电子技术中,频率是最基本的参数之一,又与许多电参量的测量方案、测量结果都有十分密切的关系,因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速,以及便于实现测量过程自动化等优点,是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计,并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门,通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率,最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求,而且具有了单片机的稳定性和成熟性,且控制能力强,是一种低成本,高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct

1. 本程序中,首先应输入一个值赋给初始报数上限m,人数n应为任意的,程序应能自动保存出列人的序号并将出列的人所持的密码赋给m,再次作为报数上限,然后删除出列人信息。如此循环,直至所有人都出列为止。
2. 程序以用户和计算机的对话方式执行,即在计算机屏幕上显示“提示信息”之后,由用户在键盘上输入相应数据(即每个人所持的密码),每个人的序号由程序自动分配并存储。
-1. This process should first enter a value assigned to the initial reported that the maximum number of m, the number n should be arbitrary, the procedure should be able to automatically save a number of people out and held out the password assigned to m again reported as the maximum number, and then delete the information out of people. Such a cycle, until all that far out. 2. Procedures to computer users and the implementation of the dialogue, that is displayed on the screen in the computer " message" after the keyboard by the user in the corresponding input data (that is, each person" s password), each individual" s serial number automatically assigned by the procedures and stored.
