A distributed system for glasshouse climate control, data acquisition and analysis

Abstract To cope with future developments in glasshouse climate control, a distributed computer system is installed at the GCRS. The hard- and software of the system are described. The system has four types of computers networked together by Ethernet. It controls and collects data from eight glasshouse blocks with over 70 different compartments. The advantages of this system are: reliability, speed, flexibility, easy servicing, user-friendliness and easy expansibility.
