Abstract
The embedded web technology is increasingly applied in precision agriculture. Based on ARM-Linux development environment, this paper constructs embedded web server and use it in acquisition and transmission of greenhouse information. The system could transmit the collected information effectively with benign stability and expansibility. Microprocessor S3C2440 based on ARM9 is used as the system processing unit, its rich resources can not only realize the system function, but also facilitate the system expansion in the future. Embedded web server Boa and embedded database management system (DBMS) SQLite are selected to construct the software system of web server. Common Gateway Interface (CGI) program is developed to implement dynamic web technology and the interaction with the users. Experiment results show that the working performance of the system is quite stable and can reach the design requirements in real-time data acquisition and remote control. Furthermore, the system has the characteristics of good expansibility, networking flexibility and low cost.
