READER DRIVER DEVICE, SYSTEM AND METHOD BASED ON LLRP (LOW-LEVEL READER PROTOCOL)

摘要

A reader driver device, a system and a method based on a LLRP (Low-level reader protocol) protocol are provided, wherein, the reader driver device based on LLRP protocol comprises a base interface, an extension interface and a communication interface. The base interface is configured to interact with upper layer application about LLRP base operation messages. The extension interface is configured to interact with upper layer application about LLRP extension operation messages. The communication interface is configured to implement the message interaction between the base interface or the extension interface and the reader. The device is convenient to re-develop the reader based on LLRP protocol, reduces the development cost obviously, and improves the development efficiency and flexibility.
