Unit and method for reader information statistics of radio frequency recognition system

Abstract

The invention provides a unit and a method for reader information statistics of a radio frequency recognition system. The unit comprises a starting module, a databank module, a file storing module and a timer module, wherein the starting module is an initialization module for starting reader information statistics; the databank module is used for completing checking, establishment and delete of tag information; the file storage module is used for establishing an information statistics control file and a reader information file; the timer module is used for deleting expiry databank memories at regular time. The method comprises the following steps: starting reader information statistics, carrying out the reader information statistics, and releasing the memory through the timer module. Through the adoption of the method, tag information can be acquired under the condition that no client is available, and moreover the statistics is only executed once, so that the data information can be conveniently compared with that of the client, and the system fault can be positioned; through the adoption of the method, the reader information can be continuously counted under the condition that the external environment is not stable, for example, the power is cut off, the fault can be conveniently positioned, and the equipment property can be mastered; moreover, the method is applicable to multiple application situations.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification, and in particular relates to a reader information statistical unit and a statistical method of a radio frequency identification system. Background technique [0002] A radio frequency identification (RFID, Radio Frequency Identify) system includes a tag and a reader. 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. [0003] The radio frequency identification system includes passive radio frequency identification and active radio frequency identification, and the essential difference between the two lies in the label...

AI Technical Summary

Problems solved by technology

In this way, in the case of lost tags, it is impossible to successfully confirm whether the fault is that the reader did not count the tags or the reader uploaded the tag information, but the client did not process the tag information due to an operation error.
