Design And Implementation Of Wheat Environment Perception System Based On ZigBee Technology

At present, China is in the primary stage of agriculture. There are many problems in agriculture, such as low level of science and technology in production and management, weak infrastructure, low level of mechanization, lack of cultivable land, low and unstable yield, quality of agricultural products is not safe.Research ZigBee technologies applied in agricultura data acquisition and transmission, has a guiding significance for improving the yield and the level of agricultural science and technology. At the same time, ZigBee technology is the key technology of precision agriculture, intelligent agriculture.The research content of this article has important practical significance.ZigBee is a short-range wireless technology standards, has low power consumption, low cost, low rate, short distance, high capacity, safe and reliable, many nodes, three kinds of topological structure and other characteristics. These features make the ZigBee technology has an important application value in intelligent agriculture, precision agriculture, consumer electronic devices, intelligent buildings, industrial control, medical, toys and games, peripheral equipment.This paper is based on the ZigBee technology.Researching and designing the acquisition module of wheat information (Guang Zhao, temperature and humidity, voltage) by CC2530 chip. Has Setted up the perception system of wheat information. The node has the advantages of simple operation, safe and reliable, many kinds of data collection, low power consumption low cost.The main research harvests are as follows:1. Access to relevant literature, study the effects on wheat role environment during wheat growth, provides a theoretical basis for select the sensor. Select the photosensitive resistance to Collect light information, alao select SHT11 sensors to collect temperature and humidity information. Design an analog sensor channel.2. Analysis and Research on the perception system of wheat information, determine the design process of the perception system of wheat information.3. Design and develop the End-device node and coordinator, and the CC2530 chip is introduced in detail. Focus on the design of the end-device node data acquisition module and low power relay module.4. Based on Z-stack protocol stack, have designed and developed the software of wheat information system and have completed the wireless sensor network.5. Through the tests, modify the problems of hardware and software, perfect the existing problems of wireless sensor networks. Finally, build the perception system of wheat information.
