Problems solved by technology

However, when Dmax does not meet the standard requirements, the current solution is to improve the RF coupling between the NFC card reader (such as EG2) and the terminal by adjusting the resonance frequency, so as to improve Dmax; but this solution will The frequency bandwidth that leads to the final test passing is small, so that in the production test process of the terminal, there are more defective machines due to the small frequency bandwidth, which reduces the product yield

Embodiment Construction

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0031] Near Field Communication (NFC for short) is an emerging technology. Terminals using NFC technology (such as mobile phones, smart phones, credit card machines, etc.) can exchange data when they are close to each other. It evolved from the integration of non-contact radio frequency identification (Radio Frequency Identification, RFID) and interconnection technology. By integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chi...

Abstract

The embodiment of the present application discloses a test method, device, storage medium and test equipment. The method includes: determining a first frequency range based on a first value of a preset parameter; wherein at least one frequency within the first frequency range The corresponding test distance does not meet the preset distance threshold value; adjusting the parameter value of the preset parameter to obtain a second value of the preset parameter; based on the second value, testing each A first test distance corresponding to each frequency; when the measured first test distances all meet the preset distance threshold, determine the second value and the first frequency range as target test results.

Description

technical field [0001] The present application relates to the technical field of Near Field Communication (NFC), and in particular to a testing method, device, storage medium and testing equipment. Background technique [0002] Felica is a non-contact smart card technology developed by Sony Corporation of Japan, which can realize fast and reliable data transmission without inserting into the read-write slot of the terminal. At present, Felica technology is widely used in public transportation, rail transit, convenience stores, access control and other scenarios. However, for the application of Felica technology, it is first necessary to pass the Felica test certification, which includes a variety of NFC card reader (Reader) compatibility tests. [0003] In the process of testing and certification, one of the test cases is to test the highest distance (MaxDistance, Dmax) at the center point, and the standard requirement of Dmax is more than 85mm. However, when Dmax does not...
