The invention relates to a 
greenhouse environment and 
irrigation control system with 
group control of multi-temperature regions, which mainly comprises a 
greenhouse control software system run in a centralized monitoring computer, a communication network 
system based on a CAN 
field bus and unit controllers distributed in various temperature regions. The unit controller comprises a 
microcontroller, a CAN 
field bus communication module, an input / output interface module for digital quantity and analog quantity, an input module for collecting sensing signals from environmental sensors and 
plant physiological sensor in a 
greenhouse and performing 
signal processing, and an output module for driving and controlling the operation of various equipments in the greenhouse. The greenhouse 
control software in the centralized monitoring computer is used for 
processing environmental and 
plant physiological information of the multi-temperature regions, performing 
control algorithm and 
strategy selection and algorithmic calculation, and real-time transmitting a control implantation action obtained based on calculation results to each unit controller to control the operation of greenhouse equipments. The greenhouse environment and 
irrigation control system with 
group control of the multi-temperature regions adopts a development method of configuration 
software, so that the overall 
system can perform 
software configuration setting on the unit controller, the sensors, the control equipments, the display interface and the greenhouse control strategy according to specific conditions of the greenhouse, so as to adapt to different requirements of different greenhouse agricultural production managements on the 
control system.
