Research On Internet Communication Technology Of Modern Agriculture Test And Control System Based On ARM7

In recent years, there is a little progress on modern agriculture in our country. However, the modern agriculture equipment are still depend on import. And the research on mordern agriculture instrument and technology in domestic are still out of date, especially on the information exchange of expert system with producdtion field through internet.. The research on modern agriculture, especially on the aspect of control message download through internet, are still in the beginning. So, the research on control message download through internet are of great importance.This paper consist of the following part:Firstly, we introduced the character and trends of modern agriculture. And introduced the technology in common use of modern agriculture.Secondly, we introduced the hardware design of modern agriculture measure and control system, and introduced the key component of the system.Thirdly, we designed the client software. In this portion, we designed Ethernet card driver software of S3C4510B,protocol service software and LCD driver software.Fourthly, we designed the server software of host machine.At last, the test on the network communication portion was implemented, and the result proved the communication portion is reliable.The design of internet communication portion involves software,hardware and network technology. The design of Ethernet driver software and protocol serve software of 32bit MPU, not only helpful to the development of modern agriculture measure and control system, but also to the application of embedded system on information devices.
