Composition Of RFID System

In actual RFID solutions, both simple and complex RFID systems contain some basic components. Components are divided into hardware components and software components. From an end-to-end perspective, an RFID system consists of electronic tags, reader antennas, readers, sensors/actuators/alarms, communication facilities, controllers, application software, etc. If viewed from the perspective of functional implementation, the RFID system can be divided into two major parts: the edge system and the software system. This viewpoint coincides with the viewpoint of modern information technology. The edge system mainly completes information sensing and belongs to the hardware component part; The software system completes the processing and application of information; Communication facilities are responsible for the information transmission of the entire RFID system.
The hardware components in the RFID system include electronic tags, readers and writers (including sensors/actuators/alarms and edge interfaces), controllers, and read and write antennas; Of course, there should also be a host in the system, application software programs for processing data, and connections to the network.
The software components in the RFID system mainly complete the storage and management of data information, as well as the reading and writing control of RFID tags. They are independent of the RFID hardware. RFID systems ultimately serve applications, and the interface between readers and applications is typically accomplished by software components. Generally, RFID software components include: ① edge interfaces; ② Middleware, which is developed to achieve the transmission and distribution of collected information; ③ Enterprise application interface refers to enterprise front-end software, such as system demonstration software, driver software, interface software provided by equipment suppliers, RFID front-end software developed by integrators or customers themselves, etc.; ④ Application software mainly refers to enterprise back-end software, such as back-end application software, management information system (MIS) software, etc.
