An environment intelligent monitoring module is developed and designed under transplanted Linux system, based on the platform with ARM11 core-based S3C6410 as the main controller. This paper mainly develops intelligent monitoring interface based on Qt. With the serial communication between modules and sensors, users can obtain the parameters such as temperature, CO₂, humidity and illuminance etc. in crops greenhouses. By using double buffer technique and pixel mapping, curve display controller is designed to reflect the global and local change trend of all kinds of parameters in the real time. Through developing a character device driver program, this module can control the relay equipment to keep environment indexes to the appropriate standards. Finally, the monitoring web page is designed and published on the server by ASP.NET technology and asynchronous refresh, with socket communication mode to complete data interaction with intelligent module. The users can remote login the system to ensure the suitability of crop growth environment and the safety of the equipment operation.
