Interprocess data communication method and device for RFID (Radio Frequency Identification Device) middleware

Abstract

The invention discloses an interprocess data communication method for an RFID (Radio Frequency Identification Device) middleware. A main module of the RFID middleware and each electronic label acquisition module of the RFID middleware both establish respective message queues; the main module of the RFID middleware regularly sends various commands to the message queues of the electronic label acquisition modules of the RFID middleware; and the electronic label acquisition modules send acquired label data to the message queue of the main module. The invention also discloses an interprocess data communication device for the RFID middleware. The interactive process of interprocess small block data is optimized aiming at the application characteristics of the RFID middleware, thereby realizing data delivery, receiving and release algorithms of constant time complexity; the invention can meet the performance requirements on the RFID middleware for real-time electronic label acquisition, is suitable for the electronic label acquisition modules of the RFID middleware and realizes the loose coupling of the main module and the electronic label acquisition modules of the RFID middleware.

Description

technical field [0001] The invention relates to the field of data exchange between RFID (Radio Frequency Identification, radio frequency identification) middleware processes, in particular to a method for data transfer between the processes of the RFID middleware main module and the RFID middleware electronic label acquisition module. The invention also relates to a device for inter-process data communication in the RFID middleware. Background technique [0002] RFID middleware can automatically identify and collect the electronic tag data of RFID equipment, and is widely used in various fields such as logistics, manufacturing and important item tracking. RFID middleware builds a data communication bridge between automatic identification (such as RFID readers) and application systems, and its most basic function is to collect and / or filter electronic tags. [0003] When the RFID reader is working, the RFID middleware will read the electronic tags continuously. In a large w...
