Problems solved by technology

However, when testing the card reader, it is necessary to prepare a memory card. If there are multiple different types of memory card interfaces on the card reader, it is necessary to prepare a memory card for each type of interface. For example, if the card reader includes SM card type interface (Smart Media Card, smart media card), SD card type interface (Secure Digital Card, secure digital card), CF card type interface (Compact FlashCard, standard flash memory card), MMC card type interface (Multi Media Card, Multimedia card), MS card t

Example Embodiment

[0011] like figure 1 Shown is the application environment diagram of the preferred embodiment of the card reader test fixture of the present invention. The card reader test fixture 2 is connected to the corresponding interface 11 on the card reader 1 through the interface 21 . The interface 21 on the card reader test fixture 2 is of the same type as the interface 11 connected to the card reader 1 . Specifically, in this preferred embodiment, assuming that the interface 21 of the card reader test fixture 2 is an MMC card interface, the interface 11 of the card reader 1 is also an MMC card interface. The card reader test fixture 2 and the card reader 1 include various types of interfaces, and the interfaces can be divided into: SM card type interface (Smart Media Card, smart media card), SD card type interface (Secure Digital Card, secure digital card), CF card type interface (CompactFlash Card, standard flash memory card), MMC card type interface (Multi Media Card, multimedia...

Abstract

The invention relates to a card reader testing tool. The card reader testing tool is connected with a computer through a card reader and comprises a microcontroller and a storing device chip, wherein the microcontroller is used for receiving a sensing command sent by the computer through an interface, recognizing the type of the interface connected with the card reader after the sensing command is received, analyzing the communication protocol of the interface and switching to the mode of the analyzed communication protocol so that data transmission complies with the criterion of the analyzed communication protocol, and the storing device chip is used for generating a read-write command in order to read and write the data on the storing device and sending the data read and written from the storing device to the computer according to the criterion of the communication protocol in order to judge whether the card reader is qualified or not.

Description

technical field [0001] The invention relates to a card reader test fixture and a card reader test method. Background technique [0002] A card reader is a specialized device that has a slot to insert a memory card and a port to connect to a computer. After inserting a suitable memory card into the slot, connecting the port to the computer and installing the required driver, the computer treats the memory card as a removable memory, so that the memory card can be read and written through a card reader. [0003] At present, after the card reader is manufactured, it is necessary to test the performance of the card reader to check whether the card reader is qualified. Usually, the way of testing is to insert a memory card into the card reader, and the computer checks the data on various memory cards. Read and write to judge whether the interface on the card reader is in normal communication. If the communication is normal, the card reader is qualified. However, when testing th...
