单片机在工业控制和测量领域有着广泛的应用。利用单片机完成卫星通用负载等效器的设计。负载等效器采用单片机作为控制核心,实现与测试服务器通信并接收服务器的控制指令,同时上传状态信息。负载等效器在整个测试网络需要通过TCP/IP协议完成与测试服务器的信息交换。单片机采用dsPIC30F6014A,按要求完成对模拟信号的A/D采样、D/A转换、串口通信、继电器控制等功能。
Microcontroller in the field of industrial control and measurement has a wide range of applications. The use of single chip microcomputer to complete the design of satellite universal load equivalent. The load is the equivalent of single-chip microcontroller as the control center to achieve communication with the test server and receive server control commands, and upload status information. Load Equivalents The entire test network needs to exchange information with the test server over the TCP / IP protocol. Single-chip dsPIC30F6014A, according to the requirements of the analog signal to complete the A / D sampling, D / A conversion, serial communication, relay control and other functions.
