CPC card pre-reading mechanism testing method and device under antenna interference

Abstract

The invention provides a CPC card pre-reading mechanism testing method and device under antenna interference, and the method employs integrated testing equipment comprising a 13.56 MHz card reader, a5.8 GHz antenna, an interference antenna and a main control module for detection, and the interference antenna is used for transmitting a square wave signal, a 5G signal and / or a 5.8 GHz signal to simulate various interference signals in a usage scene. Meanwhile, by simulating the signal frequency band, the information flow direction and the storage position in the transaction process of the to-be-tested CPC card, the use state in the actual operation process are simulated, the consistency of the first-time card reading content and the pre-reading content is compared, whether pre-reading is influenced by interference signals or not is judged and the actual simulation application process is tested, the test result is accurate and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of expressway electronic tag communication, in particular to a method and device for testing a CPC card pre-reading mechanism under antenna interference. Background technique [0002] With the promotion of the cancellation of provincial boundary toll stations on expressways, in order to increase the speed of expressway traffic and optimize the efficiency of expressway toll collection, under the premise that the national ETC (Electronic Toll Collection System) vehicle labels have not been fully popularized, the CPC card (composite traffic Card) instead of paper passes has become an important part of the national expressway pass card medium, meeting the passing needs of vehicles not equipped with ETC, and realizing vehicle passing and billing functions. [0003] During the transaction process of the CPC card, it is necessary to pre-read the transaction-related information stored in the card to calculate and re...

AI Technical Summary

Problems solved by technology

In the actual working environment of the CPC card, there are a lot of interference signals, such as electrical signals of electrical equipment or signals of the same specification in the transaction process of other CPC cards, which may cause pre-reading errors of the CPC card to be tested

With the large-scale operation of CPC cards, there have been some cases where charging failed due to pre-reading failures
