Design and Implementation of Communication Network based on AT89C52 Microcomputer

Abstract

A network configuration of monitoring system of RS-485 Bus is represented based on the characteristic of small enterprise. The network nodes based on AT89C52 microcomputer are used at production line and build a monitoring network with PC. This paper presents a detailed communication program and its flow charts. The operation of the network system is stable and widely applied in manufacturing with excellent feedback, it can provide some experience for the design of similar monitoring system.
