Design of a Measurement and Control Machine for Greenhouse Environment Parameters
In order to obtain a good control effect in modern greenhouses,a measurement and control machine for greenhouse environment parameters was designed.The machine is composed of host computer and soil moisture slave computer.The host computer is mainly used to measure and control temperature,humidity and CO2,and gives a fuzzy control operation on CO2 concentration,soil humidity and other parameters after integrating various parameters of greenhouse;at the same time,it also gives the current status and parameters of the greenhouse.The slave computer is responsible for soil humidity measurement and accepts the fuzzy control instructions from host computer;it also controls the drip irrigation by dividing the indoor partition.This structure,the data focused on the host computer,is convenient for fuzzy control expert systems data storage,modify and upgrading.It has a convenient operation and a friendly man-machine interface.The way of soil humidity zoning controlled by the slave computer can meet with the demand of various crops being planted in the same greenhouse.
