Design Of Active RFID And Its Application In Warehouse Management

As an important part of logistics industry, the efficacious and modern management of storage plays a great role in enhancing the efficiency and reducing the cost of enterprise.However, most of current warehouse management remains manual operation, which leads to low inefficiency and high costs in the incorporation, and cannot fit the demanded of fast development of our country economy. Therefore, it is an inevitable trend to realizing automatic warehouse management via advanced techniques and tools, such as automatic identification technology, computer science and wireless communication technologies,In my thesis, warehouse information system based on active radio frequency identification (RFID) is proposed to avoid the disadvantage of the traditional warehouse management system.In my thesis, previous work on automatic identification, wireless sensor network technology, logistics tracking, warehouse management systems and related techniques are presented.Against the background of airport warehouse management, an information warehouse system with active RFED is designed. The system, which is at the kernel of computer information management system, at the collection tool of active RFID, and at the information transferring tool of wireless communication, implements the airport cargo warehouse wireless management.The main works of the design and research are as follows:1) Hardware circuit of active RFID tag is designed and implemented. Especially, the interface of circuit, electrical source circuit, PCB and antenna is investigated deeply.2) Wireless communication network is constructed with active RFID tag. The data frame format of wireless communication, channel coding and collision avoiding algorithm are studied deeply. In this network, the hexagonal structure and static routing assistant of dynamic routing is used.3) The design and realization of warehouse information system software is completed.At last, the test of the whole system including hardware and software indicates that my system can manage the warehouse wirelessly and efficiently.
