【摘要】:农业物联网的发展能促进农业经济的发展,很多国家投入巨资来建设农业物联网。可以通过农业智能传感技术、农业无线传感器网络、RFID标识技术及农业信息处理模型的集成应用形成一系列智能化的信息系统,能显著提升农业生产的管理和决策水平,促进现代农业的发展。结合课题需要,分析了温湿度模块、光照模块的原理、分类和优劣势,对几种无线传感器网络的构成、特征、优劣势进行探讨分析,对RFID的构成、原理、性能指标、分类、协议和应用也进行综合分析,根据项目的需求,对这几种典型硬件进行详细分析探究。首先选择合适的温湿度传感器模块、光照传感器和单片机,项目中挑选了DHT22数字温湿度传感器、BH1750数字环境光传感器、Arduino UNO R3 和 XbeeS2无线模块来开发环境监测节点。监测节点的下位机软件设计上,需要实现环境参数的实时监测和实时发送,监测的间隔时间可自由设定。在无线传感器网络上,分析比较目前热门的几种无线传感器网络后,选择基于ZigBee技术的Xbee S2无线模块,根据项目具体要求,组建多个发送、单个接收的无线传感器网络。根据正交试验测试的结果,选了最优的AS399x RFID模块,配合Arduino UNO R3作为控制器,进行二次开发。“手持机”下位机软件开发,实现轮询标签、选择标签、读取标签用户存贮区、写标签用户存贮区等功能。通过时间标记,上位机软件把环境监测节点的数据和动物标识系统的数据综合处理。系统实现了小样本的传感器节点数据和RFID模块读写的集成,通过无线数据接收平台一体化集成了RFID读写模块和传感器节点。利用了RFID读写模块将ID信息和传感器信息标识实现了统一读、存储和反输入,变相实现了RFID与sensor的信号集成,达到了RFID-Sensor的结构实现。
[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.
