[Abstract]:At present, domestic agriculture is in the initial stage of development, there are some problems, such as low level of production, low level of management science and technology, weak infrastructure, low level of mechanization, less arable land, low yield and unsafe quality of agricultural products, etc. The research on the application of ZigBee technology in the acquisition and transmission of agricultural data is of great significance to the improvement of output and the development of agricultural science and technology. At the same time, it is also the key technology to realize precision agriculture, intelligent agriculture must be conquered. ZigBee is a kind of two-way wireless communication standard with low power consumption, low cost, low rate, close range, high capacity, security and reliability, and many supporting nodes. There are many characteristics such as abundant topology. These characteristics make ZigBee technology in intelligent agriculture, precision agriculture, consumer electronics devices, intelligent buildings, industrial control, medical, toy games, equipment peripherals and other fields of important application value. Based on ZigBee technology, this paper studies and designs the wheat environmental information collection module (illumination, temperature, humidity, voltage) based on CC2530 chip, and develops and constructs the wheat environmental information sensing system. The node has the advantages of simple operation, safe and reliable, many kinds of data collection, low power consumption and low cost. The main work and achievements of this paper are as follows: 1. The effects of environmental factors (temperature, humidity, light) on the growth of wheat were studied in order to provide a theoretical basis for the selection of sensors. Select Guang Min resistance to collect light information, SHT11 sensor to collect temperature and humidity information, and design analog sensor channel, reserved interface, convenient external connection. The requirement analysis and research of wheat environmental information perception system were carried out to determine the design process of wheat environmental information perception system. The ZigBee technology used in system design is described in detail. 3. The terminal node and coordinator are designed and developed, and the CC2530 chip is introduced in detail. The emphasis is on the design of terminal node data acquisition module and low power relay module. 4. Based on the architecture of Z-stack protocol stack, the software part of wheat environment information sensing system is designed and developed, and the wireless sensor network is constructed. 5. Through various tests, the problems of hardware and software are modified, and the shortcomings of wireless sensor network (WSN) are improved. Finally, the wheat environmental information perception system is established.
