Paper Abstract

Greenhouses can by their control systems provide a good environment for growing crops, raising crop yield and improving crop quality. According to the trait of glass greenhouse control and development trend, the paper introduces a five-level control system based on an embedded CAN-Bus. The field monitoring level using the ARM processor, is communicating with the device level via the CAN-Bus. The central monitoring level communicates with field monitoring level via TCP/IP. The paper introduced some key technologies about the software such as the CAN-Bus driver, an intelligent control strategy, a database technology and a remote control technology. The system had the characteristic of an amicable interface and a modular and open structure. It has been in use for two years in the greenhouse of the Zhejiang university of technology, which showed that the system was reliable and effective.
