Design And Research Of The Platform For Agriculture Environment's Measurement & Control Based On Wireless Network

Since coming into the 21st century, MEMS technology, computer technology, communications, autocontrol theory, EI knowledge and so on all these knowledge'sdevelopment has bring out a new networks of measurement and controllings—Wireless Sensor Networks.WSN as the new measurement and controlling technology, it is the smart network system which can implement the data collection, data confusion and transfer application. WSN combines the logical information world and true physics world. It can achieve the "Pervasive Computing or Ubiquitous Computing" mode in deed. WSN is a synthesis technology which refers a lot of knowledges, and brings out many study questions of basic theory and engineering technology.Wireless sensor networks has widely application foreground ever in national defence or other fields. Especially in greenhouse, precision framing, irrigation in farmland, pasturage and breed aquatic agriculture application has great value of application and extendtion. The study of this technology will drive the tenor of our country's information construction and advances the development of the related domain and subjects, and steps our country's national power.Now the study of wireless sensor networks' hardware platform is not widely bring out. Many of companies are using the production of oversea, which extend function is not well and is hardly come the more little consumption. So this paper is mainly analyse and study the wireless sensor networks node's hardware platform deeply. Base on the study of wireless communication technology ,memory technology, sensor technology, embedded computer and power design technologies, combining the newly production of the world. We bring forward the system framework of the wireless sensor networks, and designed the node of low power consumption & smart battery system. This paper introduced the hardware and software of wireless sensor networks node and smart battery system, also bring out the protocol of star network and self-organization mesh network, at last studied the related key technologies & the future development of wireless sensor networks. This design was bring into the greenhouse's environment. The result of the experiment was show that the wireless and network of sensor will bring a lot of convenience for agriculture information. Bring the wireless sensor networks into agriculture domain has a landmark meanings for agriculture.This paper was supported by the Beijing Municipal Science&Technology Commission's project "The study and application of smart sensor network systems in vegetable production (serial number: Z0005190040831)"...
