| 摘 要： | 为了方便地在现场监控电压或电流信号，显示出相应数值并预警出现问题的信号，很有必要设计一个低成本、观察方便、操作简易的处理系统。提出了基于数字采集及传输处理系统的基本设计思想，包括A／D转换器与单片机的接口实现，MAX485的串口传输原理及并口驱动LED等，设计出了完整的电路结构与实现软件。为了编程方便及易于调试，采用C语言作为软件编程语言，开发环境是Keil软件。

| Abstract: | In order to monitor voltage or current signals expediently at the local, display the corresponding values and alarm fault signals, it is very important to design a low cost system with convenient observation and straightforward operation. This article brings forward an idea based on a system of digital data collection, transmitting and processing, introduces the interface between the A/D converter and the single chip microcomputer, analyzes the principal of the transmitting system based on MAX485 serial ports, describes the method of driving LED by parallel ports in detail, and designs a complete circuit architecture and implemented software under this foundation. To program facilitatively and debug effortlessly, C language is adopted as the programming language and the developed environment is Keil software. |
