Abstract :
This paper discusses a greenhouse SCADA system based on CAN/1-wire double bus hierarchical network, its upper network connects HMI with RTU by CAN bus and its lower network connects RTU with various field environmental parameter transmitters by 1-wire bus. Greenhouses which adopt SCADA systems based on hierarchical network are convenient to be managed, they can isolate local faults effectively and improve system reliability. In addition, they have flexible structures and people are easy to install and use them.
