Method and device for testing pre-reading mechanism of cpc card under antenna interference

Abstract

The present invention provides a method and device for testing a CPC card pre-reading mechanism under antenna interference, which adopts an integrated testing device including a 13.56MHz card reader, a 5.8GHz antenna, an interference antenna and a main control module for testing, and the interference antenna is used for the transmitter. The wave signal, 5G signal and / or 5.8GHz signal simulates various interference signals in the usage scenario, and at the same time simulates the usage status in the actual operation process by simulating the signal frequency band, information flow and storage location during the transaction process of the CPC card to be tested. Comparing the consistency between the content of the first card reading and the content of the pre-reading, it is judged whether the pre-reading is affected by the interference signal, and the test is fully simulated to simulate the actual application process, and the test results are accurate and efficient.

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 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, CPC (Compound Pass Card) , Composite pass card, also known as CPC card) instead of paper passes has become an important part of the national expressway pass card medium, meeting the traffic needs of vehicles without ETC installed, and realizing vehicle traffic 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...

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
