Design And Implementation Of Automatic Monitoring System For Strawberry Planting Greenhouse

With the development of science and technology and the rapid implementation of agricultural industrialization,the agricultural economic and technological development of our country has entered a new stage of development, agriculture from the labor-intensive industries, gradually transformed into intensive industry, the construction of modern agriculture and improve the competitiveness of agriculture in the international market to become the current and future quite a long time of the important tasks of agricultural development, the present state of the show is only for study and application of agricultural high-tech, realize the sustainable development of agriculture in our country.This article mainly discusses the strawberry planting principle of greenhouse environment control system of strawberry were analyzed in the process of growth of greenhouse environment temperature, humidity, illumination, and the effect of co2 concentration, and on this basis proposes the overall design scheme of automatic monitoring system of greenhouse. This control scheme is widely used by industrial control field programmable logic controller(PLC) and configuration software WinCC and ProfiNet fieldbus.This article mainly strawberry cultivation in greenhouse as the research object, through the study of the system, according to the greenhouse environment variables, the characteristics of large inertia, nonlinear, it is difficult to to achieve precise control through mathematical modeling, so this system mainly USES the fuzzy control algorithm to achieve, and through the programming and other technical means to implement. This system will be based on ProfiNet fieldbus technology, data exchange between field devices and remote controller, and use the WinCC configuration software, to achieve remote status display, parameter setting of field devices, environmental data trends show multiple functions such as manual, user management and system.After a period of running the whole control system, fully embodies its control stability, rapid response, strong extensibility features, at the same time for the breeding of other crops also have high universality, for many of the crop cultivation agriculture industry base provides a theoretical and practical basis.
