Abstract
The invention discloses an automatic read-write performance detection method of RFID tags in specific scenes. The method includes the steps that firstly, a detection scene is built; secondly, scene scripts are compiled; thirdly, automatic detection is executed; fourthly, detection data are recorded; fifthly, a detection result is analyzed. Compared with an existing detection method, due to the fact that a detection control software system is used for calling a position controller to drive an asynchronous motor to automatically alter the relative positions between the RFID tags and an RFID reader of a fixed platform, detection behaviors can be automatically driven through the scene scripts; multi-scene composite lossless automatic detection of the RFID tags is fast achieved; quantitative index information of effectiveness and consistency of the read-write performance of each single RFID tag can be automatically calculated in each scene; detection of the effectiveness and the consistency of the read-write performance of the RFID tags in the specific scenes is more informative for practical application links.

D. detection data record, during carrying out step c, detection data recordin module records detection automatically
Object information, is then sequentially written in above-mentioned information in data base according to label label and time point；
E. Analysis of test results.
As preferably, in described step a, described read write line is rfid interrogator or hand-held RFID read-write device；
As preferably, in described step d, testing result data message includes that tag number id, scene are numbered
Scid, time point t, read write line are relative to the x, y, z value of tag coordinate system, speed of service v, read-write motion action
With RSSI signal strength values rssivalue；
As preferably, in described step e, from the data base of step d, extract a label pair to be analyzed
Answer information, the most just obtained testing result data sheet hyte under special scenes, then according to tag number id and
Scene numbering scid is divided into several subsets of data, and each subsets of data corresponding data is exactly single under special scenes
Data values all in this array are averaged and variance, then will be many by the RSSI signal strength values array of label
Average and the variance of the corresponding Same Scene numbering of individual label compare, and average the biggest label effectiveness is the best,
The least tag compliance of variance yields is the best.
Compared with prior art, it is an advantage of the current invention that:
1. utilize asynchronous machine structure three-dimensional position variation instrument to realize RFID label tag under special scenes to read with RFID
Write device automatically to change relative to change in location.
2. utilizing detection to control software system calling station controller drives asynchronous machine automatically to change RFID label tag
And the relative position between the rfid interrogator of fixed platform achieves employing scene script and automatically drives detection row
For.
3. realize the many scenes of quick RFID label tag and be combined automatic nondestructive detection.
Effectiveness and the concordance of single RFID label tag readwrite performance all can be automatically calculated under the most each scene
Quantizating index information.
5. reality application link is had by the effectiveness at special scenes detection RFID label tag readwrite performance with concordance
Preferably referential.
