A Design and Realization of Control System Based On Single-chip Computer Network ZHAO Hong1，CAO Xiao-lan2，YAO Zhi-cheng3 （1. Information Department, The Second Xiang Ya Hospital of Central South University, ChangSha 410011,China; 2. College of Information Science Technology, HNAU，Changsha 410128, China; 3. Hunan Changsha Weisheng Electronics Co., Ltd.，ChangSha, 410205, China） Abstract: By combining the technology of Single-chip Microcomputers and networks, a Control System Based On Single-chip Computer Network based on “AT89S52” is designed. A bus types is adopted by the networks topological structure of the system; A port transmitting form is adopted by the networks interface circuit; The System development tools of Keil 7.0 assembler 8051 compilation procedures, and AT89S52 the detailed planning of the use of memory. The system is prone to be expanded and the stability of it is advanced. Results indicate that the design makes the problem of multi-computer communication among 8-bit Single-chip Microcomputers work out easily, realizes the communication between a client computer and its server, and realizes the interactive communication among the clients as well.
