Remote Control Design And Research For The Greenhouse Based On ARM

At present,with deep-going development of computer,communication technology, and internet technology.Accurate parameters collection and analysis become reality. And this technology achievement can help to arrange the greenhouse condition control,factory farming and cultivation facilities.Computer collects the corresponding environmental parameters.On one hand, Collect the environmental parameters related to the crops growth.On the other hand,based on the collected data adjust the shading panels equipment,irrigation water equipment,heaters equipment to control the environmental of the greenhouse So as to provide appropriate environment for the corps.Consider the environment in the greenhouse,data interactive and analysis is through Ethernet.In greenhouse,many environmental factors effect the growth of crops.This article included 4 main environmental factors:temperature,humidity,CO2 concentration and light intensity.Proposed control characteristic and control methods to environment factors.Focus on greenhouse environment examination system design and key technologies.Proposed suitable environmental factors control through this system.ARM platform is the most widely used embedded processor architecture.This article uses S3C2410(ARM core)for the CPU hardware platform,Samsung S3C2410 is based on ARM920T architecture high-performance CPU.The rich peripheral interface,203MHz frequency,makes it particularly suitable transplant and application development of operating system.This article designs temperature sensor,humidity sensor,CO2 concentration sensor and intensity of light sensor.Sensors detected the signal through the I/V conversion,multi-channel analog switch-election.Filtering and amplification A/D conversion after transfer data to S3C2410 for data processing and control equipment. Achieve the environmental factor measurement and control.This article focuses on the greenhouse environment monitoring system hardware and software design.For the hardware part,introduced total design mind,various parts design thinking and the principle circuit in this system.In satisfies the system design request under premise,Choose a low price and low-power components as far as possible,so as to achieve lower costs.For the software part,elaborated the embedded Linux operating system development and transplants in detail,like U-BOOT transplant,Linux core translation and reduction,manufacture file system and driver programming and application programming compilation.Greenhouse control system is a big space,multi-parameter,multi-object and coupled with a strong and behind the non-linear control system,the strong coupling relationship among Temperature,humidity,CO2 concentration and light intensity in this system.Conventional control algorithms are not very satisfied with the results of control,this article designs Control Algorithm on Fuzzy in Greenhouse...
