Multi-temperature area group control greenhouse environment and irrigation control system

Abstract

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.

Description

Technical field [0001] The present invention relates to a new greenhouse environment and irrigation control system, in particular to multi-temperature zone group control technology, which realizes real-time control and management of independent environmental climate and water and fertilizer irrigation for up to 100 temperature zones to meet Requirements for greenhouse crop cultivation in each temperature zone. Background technique [0002] As a new high-efficiency, high-quality, large-scale agricultural production method, greenhouse production has been applied at home and abroad, and has increasingly become a trend in the development of agriculture in various countries in the world. [0003] However, looking at the key technology of greenhouse production - the development of greenhouse computer control system, the existing systems generally have complex structures and unreasonable layouts. [0004] At present, the greenhouse control system mostly adopts a two-level computer...
