Problems solved by technology

[0002] For RFID readers, the speed of reading and writing RFID cards is fast, and at present, most manufacturers use manual card swiping and stopwatch timing, and the human reaction time is about 0.15 seconds to 0.4 seconds, which will introduce manual errors. At the same time, stopwatch timing cannot meet needs

Embodiment 1

[0020] This embodiment discloses a test device for reading and writing timing of an RFID reader. The test device includes a wheel card unit, which is used to provide driving power for controlling the entry and departure of the RFID card into and out of the sensing area of ​​the card reader, and feedback that the RFID card effectively enters the reader. Time node 1 of the card sensing area;

[0021] The collection unit is used to collect and record the prompt sound or displayed image information of the card reader to read and write the RFID card;

[0022] The processing unit processes the prompt sound and image information collected by the acquisition unit, obtains the time node 2 when the reader reads and writes the RFID card successfully, and calculates the current RFID reader's single reading and writing RFID based on the obtained time node 1. The time used for card basic information.

[0023] Such as figure 2 As shown, the wheel card unit includes a working platform 1, a...

Embodiment 2

[0026] This embodiment discloses a test method for reading and writing timing of an RFID reader, such as figure 1 Shown is the flow chart of the test, including the following steps:

[0027] S01), the wheel card unit sends the RFID card into the sensing area of ​​the reader, the reader senses the RFID card and triggers the generation of a start signal and transmits it to the processing unit;

[0028] S02), the acquisition unit records the video of the process of reading and writing the RFID card by the card reader, including the prompt when the card reader reads and writes the RFID card successfully, and the prompt includes the sound information of the card reader and / or the image displayed on the screen of the card reader information, and send the collected sound information and / or image information to the processing unit;

[0029] S03), the processing unit receives the signal information transmitted by the wheel card unit and the acquisition unit, when the RFID card effecti...

Abstract

The invention discloses a test apparatus and method for read-write timing of an RFID reader-writer. The apparatus comprises a card control unit, a collection unit and a processing unit. The test apparatus is adopted for performing testing of the read-write timing of the RFID reader-writer; the problem of inaccurate timing caused by manual card swiping and stopwatch timing is avoided; and the apparatus can repeatedly perform RFID card read-write operation and then perform repeated timing to achieve quantization. By adopting a calculation method for reducing errors, the timing precision is improved. According to the apparatus, an error which is about 0.05-0.1s is introduced; the precision can reach 0.1s; and the test demand of the read-write timing of the reader-writer is met.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification (RFID) reader-writers, in particular to a test device and method for reading and writing timing of an RFID reader-writer. Background technique [0002] For RFID readers, the speed of reading and writing RFID cards is fast, and at present, most manufacturers use manual card swiping and stopwatch timing, and the human reaction time is about 0.15 seconds to 0.4 seconds, which will introduce manual errors. At the same time, stopwatch timing cannot Meet the needs. How to time the RFID reader-writer in order to detect the time occupied by the reading and writing process of the RFID reader-writer is precisely timed. For each RFID reader-writer manufacturer, it is necessary to invent a RFID reader-writer reading and writing timing test device . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a test device and method fo...
