Universal read-write machine communicating method based on EPC read-write machine specification

Abstract

A general reader communication agreement based on EPC reader agreement comprises a reader and writer layer, an information layer, a transmission layer; wherein, the reader and writer layer are responsible to abstract an operation request of users to a method and an attribute of an executed object which is then transmitted to the information layer, or to receive the method and the attribute of an operated object and the executed object from the information layer to transform into requirements; the information layer is responsible to encapsulate the method and the attribute of the object which is abstracted out by the reader and writer layer into a request message, or to tell out the method and the attribute of the operated object from the receiving and request message of the transmission layer; simultaneously, the host computer processing request message actively responds to the processing, and the reader processing and receiving request message actively responds to the processing and sending; the transmission layer is responsible to send the well-encapsulated message of the information layer to one end of the network, to receive the message sent from the other end, and then to sent the message to the information layer. The invention establishes the unified and general reader equipment communication agreement, reduces the difficulties in the integration of heterogeneous system and in the application and development of the upper layer, and further enhances the frequency identification adaptability.

Description

technical field

[0001] The invention relates to a general RFID reader-writer communication method, in particular to a general RFID reader-writer communication method based on EPC protocol. Background technique

[0002] Radio Frequency Identification (RFID) 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. From the perspective of the overall framework and application development of RFID, the core technology used to connect front-end RFID equipment with back-end enterprise application systems is becoming more and more important. For the actual deployment of RFID solutions, the ultimate goal is to collect data from various sources for business use. Users will first face how to connect front-end data with their back-end business systems, and secondly, how to ensure t...

[0026] 1. The specific design of the reader layer

[0027] The functions of the reader layer are as follows:

[0028] (1) Specifying the content and abstract syntax format of the information exchanged between the reader and the host is the core of this protocol. This layer defines the operations performed by the reader and the meaning of the operations. The types of operations include tag filtering and event generation , device management, antenna management, data filtering and interface management, etc.;

[0029] (2) The reader-writer layer must describe the logical functions of the reader-writer communication protocol in detail and accurately between the host and the reader-writer, and must solve the interrelationships of various types of operations. The device must have a unified understanding of the operation of the reader. In order to further explain the types and interrelationships of various operations, the reader layer uses object modeling to describe the functions it...
