In the past decade, the researchers and manufacturers have had developed their own environment control systems after the long run development. All these systems are all integrated environment control systems, but their software and hardware are almost incompatible with each other. Meanwhile it isn't easy to establish extra control spots. So the potential users had to set up more control spots in advance than the actual needs for the possilbe future development. The result will be higher initial investments, more complicated wire connections and then more errors those were hard to be repaired.Due to the shortages metioned above, the foreign greenhouse environment control system had already been developed as the ubiquitous system."The ubiquitous environment control system (UECS) can achieve pre-setting environment control goals by obtaining meteorological data and control strategy through wireless network IC modules put on those environment control equipment and sensors."This project will deliver the meteorological data, which detected by all those sensors to the corresponding modules of environment control system wirelessly. After receiving the related data, each build-in microprocessor in the environment control system modules will send out the command to the control equipment according to the pre-setting modes. By doing so, the system can achieve the function of self-control-module. The mainframe can be set in different control strategies to every single module according to the users' demands. At the same time, each module and sensor can send out the start up/shut down signals and meteorological data to mainframe wirelessly to achieve the function of distributed controling, and concentrated mornitoring.
