基于单片机的嵌入式多节点网络通信系统设计
Design of embedded multi-node network communication system based on single chip microcomputer
摘要
Abstract
The traditional network communication system has the problems of low data transmission speed,high transmis-sion energy consumption and poor stability. Therefore,a design of embedded multi-node network communication system based on single chip microcomputer is presented. The high-speed 8-bit microcontroller C8051F020 is taken as the main control chip of the embedded multi-node network communication system. The linear optocoupler HCNR200 is used to filter and regulate the operational amplifier circuit. The low dropout linear regulator is used to convert the output voltage of power supply. The main control chip is connected with each module of the system to control the transmission energy consumption of node data by means of dual-band structure. A threshold is set in the software of the system. If the communication distance in the cluster or the com-munication distance among the clusters is less than the threshold,the communication channel maintains a sleep state;otherwise the channel executes the task immediately,by which the design of network communication system can be accomplished. The ex-perimental results show that the proposed method can enhance the stability of the system,reduce the transmission energy con-sumption of the network communication node,and improve the speed of data transmission.关键词
