数字频率计的设计可以分为测量计数和显示。其测量的基本原理是计算一定时间内待测信号的脉冲个数，这就要求由分频器产生标准闸门时间信号，计数器记录脉冲个数，由控制器对闸门信号进行选择，并对计数器使能断进行同步控制。控制器根据闸门信号确定最佳量程。-The design of digital frequency meter can be divided into measurement and display count. The basic principle of its measurement is calculated under test signal within a certain period of time the number of pulses, which have a standard requirement by the divider gate time signal pulse counter records the number of signals from the controller to choose the gates and counters to make off synchronous control can be carried out.Controller based on the gate signal to determine the optimum range.

根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警。-err
