The range of RFID applications is more wide, currently manufacturing, logistics, medical, transportation, retail and other fields. However, in addition to label, antenna, equipment, the operation of the RFID system, can be quickly promoted. Middleware (MiddleWare) can be called the central center because it can accelerate the advent of key applications.
The RFID middleware plays an intermediary role between RFID tags and applications, providing a set of universal application interfaces (APIs) from the application side, which can be connected to the RFID reader, read RFID tag data. In this way, even if the database software or backend application of the RFID tag intelligence increases or changes other software replacement, or if it is read and writes the RFID reader type, the application does not need to be modified, and it can be handled. Multi-to-multi-connection maintenance complexity problem.
The RFID middleware is a message-oriented middleware, and the information is in the form of a message, which is transmitted from one program to another or more programs. Information can be transmitted in asynchronously, so the sender does not have to wait for a response. Message-oriented middleware contains more than delivery information, but also to interpret data, security, data broadcasting, error recovery, positioning network resources, finding a cost-effective path, the priority order of messages and requirements, and extension Wrong tool and other services.
RFID middleware can be divided into two types from the architecture
The application-centric design concept is the API provided by RFID Reader vendors, and the ADAPTER that reads data directly by using a specific Reader is directly written to the backend system, which is transmitted to the backend system or the rear-end system or The purpose of the service series.
With architecture as the complexity of the enterprise application system, enterprises cannot write Adapter to each application in the Hot Code mode, while facing object standardization, companies can consider using the manufacturer's standard specifications of RFID middleware . In this way, even if the database software that stores the RFID tag intelligence is replaced by other software, or if the RFID READER value of the RFID tag occurs, the application does not modify it.
Characteristics of RFID middleware
In general, the RFID middleware has the following features:
Since the architecture RFID middleware is independent and between the RFID reader and the backend application, and can be connected to multiple RFID readers and multiple backend applications to mitigate the complexity of architectural and maintenance.
The main purpose of the data stream RFID is to convert the entity object to a virtual object in an information environment, so data processing is the most important function of RFID. The RFID middleware has data collection, filtration, integration, and transfer, etc. to pass the correct object information to the latter application system.
The processing stream RFID middleware adopts program logic and stored functions to provide sequential message flow, with data stream design and management.
Application of Standard RFID for Automatic Data Sampling Technology and Identification Entity Objects. The world's unique identification number of various products is currently proposed, namely EPC (product electronics coding). EPC is in the supply chain system, with a string of numbers to identify a particular item, and after reading the wireless RF Identifies, the process is transmitted to the computer or the application system is called an object naming service. The object naming service system locks a fixed point in the computer network to grab the message about the product. EPC is stored in the RFID tag, after being read by the RFID reader, you can provide the name and related information represented by the EPC, and immediately identify and share item data in the supply chain, and efficiently provide information transparency.
In RFID applications, permeability is the key to the entire application, correctly capture data, ensuring the reliability of data read, and effectively transmitting data to backend systems. The data transparement between traditional applications is solved by an intermediate piece architecture and thereby developing a variety of Application Server applications.
