Card reader testing tool and card reader testing method

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 analyzedcommunication 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...

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 Flash Card, standard flash memory card), MMC card type interface (Multi Media Card , multimedia card), MS card type interface (Memory Stick, memory stick), XD card type interface (Extreme Digital Card, extreme digital card), TF card type interface (Trans Flash Card), users need to prepare SM card, SD card , CF card, MMC card, MS card, XD card and TF card, thus increasing the testing cost of the enterprise

In addition, during the test, the computer needs to install the corresponding memory card driver. Installing so many drivers is not conducive to the stability of the computer, increases the load on the computer, and reduces the efficiency of the test.
