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.
