简易谐波分析仪
采用12位MAX 197对外部信号采样。采用全周波傅立叶积分算法，对采样信号进行处理，对电力系统的电压有效值、功率等特征量进行实时在线监测；采用全数字测量法测量相位差；并采用自适应技术调整采样间隔，消除非同步采样对计算造成的误差，利用PIC18F458捕获功能实时监测电力系统频率波动，修订采样间隔。分析了各量的测量误差，均达到标准。并提供友好的人机交互界面。(used 12 MAX 197 pairs external signal sampling. Using Fourier-Cycle Integration Algorithm for the sampling signal processing, power systems to the RMS voltage, power characteristics of the volume in real-time on-line monitoring; All digital measuring method phase difference; Adaptive technology and the sampling interval, the elimination of non-synchronous sampling of the calculation error using PIC18F458 capture real-time monitoring of power system frequency fluctuations amended sampling interval. The analysis of the measurement error are up to standard. And to provide a friendly man-machine interface.)

multi
基于RS485的简单现场总线通信系统设计，功能如下：单发单收，在发送状态，能够连续发送从0到99的数字；
单发单收，在接收状态，能够接收数据，并在数码管上正确地显示出来；
单发多收，在AB完成的基础上，接上多个接收设备，能够正确发送和接收；
(Based on a simple RS485 field bus communication system design, the following functions: single single collection, sending state, can be continuously transmitted from 0 to 99 single single collection, in the receiving state, capable of receiving data and digital tube correctly displayed single overcharged, on the basis of completion of the AB, connected to multiple receivers, can correctly send and receive )
