简易信号发生器：有原理图，仿真图，C程序，功能比较齐全

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.

这是一套基于单片机的温湿度测量系统，里边附有设计的原理图，pcb图，以及烧写程序代码（keil c51编写的）。温湿度传感器使用的是dht11，性价比高。该系统除了能显示温湿度以外，还能设置温湿度报警阈值。设计的pcb板，小巧，使用。这是本人的毕业设计，有实物为依据，具有可操作性。-This is a single-chip microcomputer-based measuring system of temperature and humidity inside with schematic design, pcb plans, as well as the programmer code (keil c51 prepared). Temperature and humidity sensors are used dht11, cost-effective. Except that the system can display temperature and humidity outside, but also set the temperature and humidity alarm threshold. Pcb board design, compact, use. This is my graduation project, there is the physical basis of operational.

At can be given its arguments in a file. You can comment out lines by preceding them with either # or - characters. This is an easy way to temporarily disable some commands. The CONTINUE-command is most useful at the end of the file. When this command is read, the file is started again from the beginning. You can use it situations where the machine is not shut down for the night and you want to run some commands every day.- At can be given its arguments in a file.
