[Abstract]:There are two important communication technologies in wireless communication, namely wireless sensor networks (WSNs) and radio frequency identification (RFID). They have their own advantages and disadvantages. It will be a hot spot in the future to combine the two technologies effectively and maximize the advantages of the two technologies. Wireless sensor network is composed of a large number of sensor nodes deployed in the area to be monitored, and a WSN network system is formed by means of zigbee network, which has the characteristics of multi-hop and self-organization. Radio frequency identification (RFID) technology can automatically identify the object identity information. Through the wireless electromagnetic wave signal realization. RFID technology and WSN technology has its own technical advantages and disadvantages. RFID technology can effectively obtain object identity information and location information. However, the transmission distance is limited. WSN technology has the advantages of collecting environmental information, long-distance transmission, flexible networking and so on, but it can not obtain object identity information. An effective fusion of RFID and WSN can be used to design a communication system that can not only obtain environmental information, but also obtain object identity information at the same time. The main contents of this paper are as follows: (1) firstly, the requirements of the system are analyzed. In the background of practical application, the system technology is analyzed, and the system architecture of integrating RFID and WSN is analyzed in detail, and each kind of fusion architecture is analyzed. On this basis, the system design scheme of this paper is established. The system hardware design is realized by adopting the fusion mode of WSN node of RFID reader and designing WSN node with RFID function. It includes RFSN node (WSN node fused with RFID reader) and hardware implementation of convergent node. This paper introduces the hardware design of WSN node with RFID function, including the schematic design and PCB drawing of zigbee reader module and temperature and humidity sensor module, and introduces the hardware design of convergent node. Including ZigBee module and USB to serial port module schematic design and PCB drawing. Each module is welded and debugged, and then the power consumption of the node is evaluated to realize the software design of the system, including the software implementation of the RFSN node and the convergent node. This paper introduces the design of WSN node software with RFID function, including the design of RFID system tag program and reader program, the development of temperature and humidity sensor control software, the software design of convergent node, including the development of Z-stack protocol stack. The convergent node creates the network process and communicates with the host computer. Then the program design of upper computer interface is introduced. Finally, the information obtained by terminal nodes is presented to the user on the interface. Finally, the WSN nodes with RFID function are tested by zigbee network. It can display temperature and humidity information as well as label information on the upper computer.
