[Abstract]:The development of the agricultural Internet of things can promote the development of the agricultural economy. Many countries have invested a lot of money to build the agricultural Internet of things. The integrated application of RFID identification technology and agricultural information processing model in agricultural wireless sensor networks forms a series of intelligent information systems, which can significantly improve the management and decision-making level of agricultural production and promote the development of modern agriculture. The principle, classification and advantages and disadvantages of temperature and humidity module and illumination module are analyzed. The constitution, characteristics, advantages and disadvantages of several wireless sensor networks are discussed. The composition, principle, performance index and classification of RFID are discussed. The protocol and application are also analyzed comprehensively. According to the requirements of the project, the typical hardware is analyzed and explored in detail. First of all, the appropriate module of temperature and humidity sensor, light sensor and single chip microcomputer are selected. In the project, DHT22 digital temperature and humidity sensor, BH1750 digital environmental light sensor, Arduino UNO R3 and XbeeS2 wireless module are selected to develop the environmental monitoring node. In the software design of the monitoring node, it is necessary to realize the real-time monitoring and sending of the environmental parameters. The interval time of monitoring can be set freely. After analyzing and comparing several popular wireless sensor networks, we choose the Xbee S2 wireless module based on ZigBee technology, and set up a number of transmitters according to the specific requirements of the project. According to the results of orthogonal test, the optimal AS399x RFID module is selected, which is combined with Arduino UNO R3 as the controller to carry on the secondary development. Read tag user memory, write tag user memory, etc. The upper computer software integrated the data of the environmental monitoring node and the data of the animal marking system. The system realized the integration of the sensor node data of small sample and the reading and writing module of the RFID module. The RFID read-write module and sensor node are integrated through the wireless data receiving platform, the ID information and sensor information identification are read, stored and inverse input by using RFID read-write module, and the signal integration between RFID and sensor is realized in a disguised form. The structure of RFID-Sensor is realized.
