Design and Implementation of Master-slave Network Communication Based on TCP and UDP

摘要

The design of telecommunication system based on TCP and UDP is proposed using master-slave mode between host computer and microcontroller. PC is used as master computer, several microcontrollers as the slave microprocessor, and local area networks is built by means of route, which realizes rapid data transmitting in a network. The hardware design of network communication module, ENC28J60 is given out. Interactive interface of Network Debug Assistant based on LabVIEW programming is introduced in detail, which achieves switching from TCP to UDP, and the collected data are used as open data source for further processing. It effectively solves the problems of complicated operation and inconvenience to transplant in present communication systems, which provides a useful operational platform for communications between master and slave processors.
