Abstract


Radio Frequency Identification (RFID) is a kind of non-contact automatic Identification technology which has a broad prospect of application. In the RFID application system, the RFID middleware is one of the important components. It works as a bridge connecting the RFID reading and writing equipment and the upper application system and is responsible for data interaction between them. The scale of RFID industry ranks among the top in the development of networking technologies. In addition, its application has already spread all over in areas like intelligent industry, animal husbandry, agriculture, logistics, transportation, trade, environmental protection, military, medicine, construction and so on, which simplifies the industry application structure and brings conveniences to its users as well as great benefits to enterprise. The essence of the Internet of things is to connect the RFID technology with the network system and database of the real environment so as to set up a network consisting a large number of networking reading and writing equipment and labels spreading all over space which is stronger and more comprehensive than the Internet. As the current market application tends to be increasingly complex, the demand for embedded RFID middleware is becoming more and more intensive. The study of embedded RFID middleware with high performance is of great importance to the popularization and application of the RFID middleware technology.One of the difficulties for the promotion of Embedded RFID middleware of is the limited resources environment, which requires a reasonable allocation and optimization system resources on the basis of guarantying the proper functioning of each modules of the system. The system framework of embedded RFID middleware proposed here is divided into three levels according to their function and structure, that is, equipment management, data management, and application interface layer. Besides, the realization of each level’s function is divided according to modules in order to make the realization of each level’s function independent to some extent as well as to facilitate their tests, which would then realize functions of equipment control, network management, label data’s reading and writing, data analysis, data filtering, data storage and so on. By unified supervision of reading and writing equipment, all kinds of equipment are standardized with providing only one kind of standard interface to the upper system. Changes in the number and type of bottom equipment will not affect the accessing operation of the upper applications. In addition, the use of data scheduling method eases the pressure of data processing in the application environment, which speeds up the whole operation rate and improves the system’s performance.In the last part, the paper makes a test to verify the designed embedded RFID middleware among the embedded development platform environment in the laboratory. From data processing such as the floor label data reading and writing, reading and writing equipment management, data analysis and filtering to accessing operation of the application layer users, which covers the whole system function structure, the test results show that all modules of the embedded RFID middleware function well, and the performance indexes meet design requirements. The whole embedded RFID middleware system has clear structure as well as good flexibility and expansibility.
