Introduction to rfid
Radio frequency identification (RFID) technology is a fast, real-time, and accurate information collection and processing technology that can uniquely and effectively identify physical objects through radio frequency signals. It can be widely used in production, retail, logistics, transportation, medical care, national defense, animal husbandry, Various industries such as mining.
The basic radio frequency identification system generally consists of three parts: tags, readers and application support software. Middleware is an important part of application support software, and it is a bridge connecting hardware devices such as tags and readers with enterprise application software such as ERP and CRM. The main task of the middleware is to filter, summarize, calculate and group the tag-related data from the reader, reduce the large amount of raw data from the reader to enterprise applications, and generate event data with semantic interpretation. It can be said that middleware is the "nerve center" of the RFID system.
For the design of RFID middleware, many issues need to be considered, such as how to achieve multiple quality attributes of software, how to isolate middleware from hardware devices, how to deal with the relationship with device management functions, how to achieve high-performance data processing, and so on.
RFID system shared public service platform provides root node object name service (ONS), enterprise application authentication management, label information discovery, enterprise authorization code management and other public services. Among them, the root node ONS and the internal ONS of all enterprise RFID systems form an ONS tree. Any tag can find the address of the tag information database corresponding to the tag in the ONS tree, that is, it can further access the detailed information corresponding to the tag.
