Research On Auto Control System Of Intelligent Greenhouse

Facilities griculture is the most energic new industry in the 21st century, and greenhouse is a typical representions, while auto measure-control system is a very important part of modern intelligent greenhouse. The domestic and overseas planting practices show that improve the autocontrol and manage level can fully exrt the efficiency of greenhouse.The research on autocontrol system of intelligent greenhouse, which is hot in agriclutral greenhouse, uses sensor, communicati on, auto-measure technology and PC technology, designs a system which can real-time realize to measure and control the temperat ure,moisture,illumination and the consistency of CO₂. By autocontrol of the system, circumstance parameters of greenhouse can be in best ,and the greenhouse can provide plants a good growth environment. And it can automatically adjust the parameters base on the need of users, when parameters overrun the deadline, the system can make sound-light alarm.The system adopts distributing configuration and multi-cpu design thoughtway , which consists hypogyny-system , epigynous-system .And Epigynous-system is an environment parameters collection system, which bases on 80C31 SCM, can fufill the fucntion of collection, display and storage of environment parameters of greenhouse, and it can give sound and litht alarm when parameters overrun. Hypogyny-system can provide a good interface for peple, convenience people to use the system , and hav a general management of parameters, completes to diplay, store parameters of greenhouse and query , statute and print data realtime, which utilizes RS-232C to communicate with epigynous-system,what' s more it can display the running statesof every greenhouse and the greenhouse out of place.The system has such characteristics:!)uses distributing configuration, which can realize expediently the management of greenhouse ,and all the epigynous-systems are all independent, collocate neatly, and high reliability .2)adopts STD general lines, epigynous-system is good universe and strong expansibility .which is convenient for debug and maintenance. 3)anti-jamming technology,this system respectively designs anti-jamming for hardware and software, such as shield, insulation, trap, and so on, so has a high reliability.At last, we have a good result of the system in the running test, the softeware can work well with the hardware, and has characteristics such as high reliability and good expansibility, can control the greenhouse well, reach the purpose, and has good economic and social profit.
