The Device Driver Design Of Intelligent Embedded Linux Green Control System Based On Samsung S3C6410X

Greenhouse cultivation, a major breakthrough in the history of the developmentof agroforestry, which aims at building a best environment for plants’ growing bymeans of keeping warm, heating, providing enough light and appropriate humidity,helping plants grow rapidly and bloom also fruit ahead of time. Greenhousecultivation has made the human’s unimaginable dream came true, such as eating freshvegetables and fruits in off-season, seeing beautiful flowers in cold winter, bringingconsiderable economic benefits to growers at the same time. While nowadays thegreenhouse cultivation in our country, compared with the advanced automatedgreenhouse cultivation in the developed European and American countries, is still justthe simplest of plastic film mulching cultivation, lacking of the related technicalequipment, and the degree of plant production is highly depended on whether thegrowers are experienced or not, brings too much unpredictable for plant production.Thinking about this, we put forward the intelligent greenhouse control system in thispaper.The intelligent greenhouse control system is the developing direction of modernagriculture. The intelligent greenhouse control system is based on the artificialestablishment ambient air temperature system, simulates the optima climatope that themost appropriate environment for plants growth, eliminates the disadvantageousfactors of crop growth at maximum limit, keeps the crop staying in a state of optimalgrowth environment, reduce the cycle of the plant growth, raise production, so thenachieve the economic benefits of little cost, low risk and high production, ofeconomic benefits. The intelligent greenhouse control system detect the corresponding parameters firstly of the greenhouse environment and acquire theparameters, then concludes a data compared with the parameters that users storagebefore, and the CPU will seconded corresponding devices to take actions to changethe environment around rely on the data just acquired, so as to keep the plant stay asuitable environment all the time.In this paper, we put forward intelligent embedded linux green control systembased on Samsung S3C6410X CPU, this CPU is based on ARM11processor cores,and detects the environment parameters by the external temperature humidity Sensor,light intensity sensor and carbon dioxide concentration sensor, and the CPU willseconded corresponding devices to take actions to change the environment aroundrely on the parameters just acquired, these devices may be water curtain, sunshade,trap-door, ventilator scoop and fill light.In this paper, we will use a hardware which is an association of a core plate and abottom plate. The core plate is UP-CUP6410, and its CPU is Samsung S3C6410Xbased on ARM11core. The function of bottom plate is to drive external equipment,such as stepper motor, temperature humidity Sensor, light intensity sensor, carbondioxide concentration sensor and so on. At the same time, the hardware system isequipped with alarm device, light, electrical source to ensure the stabilization of thesystem.The Linux operating system, we choose the Fedora10and cut Fedora10into theembedded system that we need. We will also transplant Linux kernel, allocate theU-boot and root file system, develop the relevant driver program, and developapplication program by QT to realize human-machine interaction.
