Problems solved by technology

[0004] The shortcoming of a method for detecting the read-write distance of the reader-writer in the above-mentioned prior art is: the continuous adjustment and real-time feedback of the read-write distance of the reader-writer cannot be realized. Such a detection method is not only time-consuming and labor-intensive, but also The detection result is inaccurate, and it cannot meet the continuous adjustment of the measurement distance and accurately judge the reading range and dead zone of the reader.

Abstract

The embodiment of the invention provides a method and apparatus for detecting reading and writing distances of a radio frequency reader-writer. The method mainly comprises the following steps that: a distance between a card and an antenna of a reader is set as an initial distance through a card driving system, and the reader-writer performs card information reading on the card through the antenna; after successfully performing the card information reading on the card, the reader-writer transmits card driving signals to the card driving system, and a current distance between the card and the antenna of the reader is recorded through an upper computer; and after receiving the card driving signals, the card driving system adds a set distance numerical value to the distance between the card and the antenna of the reader, and the reader-writer performs card information reading on the card through the antenna, wherein the distance of the card is adjusted. With the method and apparatus for detecting reading and writing distances of the radio frequency reader-writer provided by the embodiment of the invention adopted, rapid, accurate and real-time detection of the reading and writing distances of the radio frequency reader-writer can be realized, and it can be ensured that the distances between the card and the reader-writer can be continuously adjusted in a certain distance range, and dead zones which may possibly appear in a reading and writing process of the reader-writer can be accurately grasped.

Description

technical field [0001] The invention relates to the technical field of radio frequency readers, in particular to a method and a device for detecting the reading and writing distance of a radio frequency reader. Background technique [0002] With the development of the information industry, the use of 13.56MHz readers is becoming more and more common, and readers suitable for different occasions have emerged as the times require. In the development process of the 13.56MHz reader-writer, the read-write distance of the reader-writer is an important indicator in the product development process, and the detection, debugging and optimization of the read-write distance of the reader-writer is undoubtedly an important Work. In the product development and post-test stages, a device that can quickly and accurately detect the reading and writing distance of the reader is needed to improve development efficiency and to make a more objective judgment on the reading and writing performan...
