Radio frequency identification method and system, reader, and business application device

Abstract

The invention provides a radio frequency identification method and system, a reader, and a business application device, and pertains to the field of radio frequency identification. The radio frequency identification method comprises the following steps: LLRP connection between an own port of the reader between a corresponding business application device is established by the reader; a business rule is received by the reader from the own port through the LLRP connection; and the reader is used to perform business operation according to the business rule, and send the business operation result to the business application device corresponding to the port through the LLRP connection. According to the technical scheme of the invention, when a plurality of business applications exist in one scene, the radio frequency identification cost can be reduced, and the radio frequency identification efficiency can be improved.

Description

technical field [0001] The invention relates to the field of radio frequency identification, in particular to a radio frequency identification method and system, a reader, and a service application device. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identify) system includes tags and readers. It is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. In addition, the background application and the reader in the RFID field generally use the Low Level Reader Protocol (LLRP). LLRP is a standard UHF RFID system used by the background application and the communication protocol between the re...

Problems solved by technology

However, this method has the following disadvantages: First, with the increase in the number of business applications, the cost of reader equipment and various related engineering transformation costs must be continuously increased; second, the number of reader equipment in one location will reach a saturation state, after exceeding this saturation state, there will be mutual interference between reader devices, resulting in a decline in radio frequency identification performance

However, the middleware needs to implement the complex ALE protocol to achieve the purpose of distribution, and the background application must also be familiar with the complex configuration and data usage rules of ALE, which increases the software cost and development difficulty
