In view of these shortcomings this frequency meter has made the radical innovation in the design its merit is: Uses the core component is the advanced monolithic special-purpose frequency measurement component -- monolithic frequency meter the integration rate is high the volume is small consumes the electricity province function has realized the frequency meter high integration and the microminiaturization; So long as the monolithic frequency meter adds on the crystal oscillator the measuring range choice the frequency demonstrated and so on the very few components then constitute DC to the 10MHz miniature basic frequency measurement electric circuit; But the biggest merit was this frequency meter has realized monolithic frequency meter frequency sampling electric circuit and the monolithic microcomputer three between hardware and the software connection completely caused the frequency measurement measuring range the choice the frequency data survey the sampling as well as the code frontier transformation and the data dump possible monolithic microcomputer software programming automatically to carry on thus has realized the frequency measurement and the sampling work intellectualizes completely causes this system already to be possible to constitute a miniature intelligence to measure rate the instrument core electric circuit independently also might take in the large-scale automatic control or a test system intelligent subsystem.

摘要传统的测频仪器体积很大，耗能量大，主要靠手工操作，而最大的缺点是不可编程，其量程转换、数据测量、采样控制和处理等均不能通过程序指令来进行控制，无法作为一个微型智能子系统与某一大型自动控制或测试系统进行接口。针对这些缺点，本频率计再设计上作了根本的革新，其优点是：所用核心器件是先进的单片专用测频器件——单片频率计，集成度高，体积小，耗电省，功能强，实现了频率计的高度集成化和微型化；单片频率计只要加上晶振、量程选择、频率显示等很晌慰的器件即可构成一个DC至10MHz的微型基本测频电路；而最大的优点则是本频率计完全实现了单片频率计、频率采样与单片微机三者之间的硬件与软件接口，使得测频量程的选择、频率数据的测量、采样以及编码的边境转换和数据的转储均可能过单片微机的软件编程自动进行，从而实现了测频与采样工作的完全智能化，使得本系统既可独立构成一个微型智能测率仪器的核心电路，也可作为大型自动控制或测试系统中的一个智能子系统。关键词高度集成化，单片机，频率计，电路
