Combining single-chip microcomputer technology and computer network technology, a single-chip microcomputer network control system based on AT89S52 is designed. The system network topology adopts bus type; the network interface circuit adopts the form of port forwarding; the assembler of the development tool Keil 7.0 is used to assemble the 8051 program, and the use of AT89S52 memory is planned in detail. The results show that this system design solves the problem of multi-machine communication of 8-bit single-chip microcomputers, realizes the communication between client and server, and between client and client, and is easy to expand and has good stability.
