摘　　要：Freq - 4DF是一种基于AT89C2 0 5 1单片机设计的自适应时标选择嵌入式智能频率计 .它采用模糊集合算法编写自适应时标选择程序 ,以UART方式发送测量数据 .具有最小硬件支持 (单片 2 0 5 1) ,可方便地嵌入到用户系统中 ,自动完成频率信号的测量、显示 ,以及与用户系统之间的实时数据传输 .测量范围 0 .1Hz～ 1MHz,TTL信号 。The Freq-4DF is a kind of self-adapted embedded intelligent cymometer based on AT89C2051. Its time-standard selective programs are based on fuzzy arithmetic and the measured data are output in accordance with the UART model. The Freq-4DF can be embedded into users' systems. Its function includes measuring and displaying the frequency signals, and transmitting real time data between users. Its measurement, identical with that of the common frequency meters, is from 0.1Hz to 1MHz, and it's adapted to TTL signals.
