Embodiment
Relevant characteristics and implementation of the present utility model, conjunction with figs. is described in detail as follows most preferred embodiment:
The utility model provides a kind of measurement jig 300 of card reading interface 110.Notebook provides storage card slot, in the storage card slot can be but be not limited to CF (compact flash card, CompactFlash) interface, SD (secure digital, Secure Digital) interface, MS (memory stick, Memory Stick) interface, SM (intelligent storage medium Smart Media) interface, XD (expansion card) interface, MSP interface (advanced storage rod, Memory Stick Pro) or the storage card of MMC (multimedia storage card, Multimedia Card) interface.In measurement jig 300, comprise: connecting portion 310, storage card 320, switch unit 330 and connecting circuit 340.
Please refer to shown in Figure 3ly, it is the utility model and notebook connection diagram.In measurement jig 300, be provided with the storage card 320 of multiple different size, and it is integrated on the circuit board.Connecting portion 310 is in order to be electrically connected between storage card slot 111 and the switch unit 330.For reducing plug for storage card slot 111, so then being design, the outward appearance of connecting portion 310 is consistent with storage card slot 111, and the memory card interface that has in the corresponding stored card slot 111.So in measurement jig 300, comprised the storage card 320 of plurality of specifications interface simultaneously, for example, Compact Flash, SD storage card, MS storage card, SM storage card, XD storage card, MSP storage card (Memory Stick Pro Card) or MMC storage card.When connecting portion 310 was placed in storage card slot 111, the memory card interface that is had in measurement jig 300 and the storage card slot 111 was electrically connected.
Connecting circuit 340 is electrically connected between switch unit 330 and the storage card 320, connecting circuit 340 detects data to storage card 320 in order to transmit, and export notebook to by storage card slot 111, make notebook in order to detecting the detection data and the detection data after the access before the access, judge the whether signal of normal operation of storage card slot 111 so as to exporting.Notebook sends the Serial Peripheral Interface (SPI) order and selects the pin position in order to the chip that triggers in this kind storage card 320.
The operation workflow of measurement jig of the present utility model, its method of testing comprise the following steps, please also refer to shown in Figure 4: integrate a plurality of storages and be stuck in (referring to step S410) in the measurement jig.The memory card interface that is had in measurement jig and the storage card slot is electrically connected (referring to step S420).In a plurality of storage cards, select a storage card to be measured, and make chosen storage card set up communication relation (referring to step S430) by the corresponding storage card interface in measurement jig and the storage card slot.Send one and detect data to chosen storage card, read the detection data of transmission again from chosen storage card, and detection data that send and the data that read are done one relatively, with the memory card interface of judging correspondence in the storage card slot whether make a mistake (referring to step S440).And repeating step S430 selects other storage card, until all memory card interfaces are tested finish till.
Be clear interpretation detailed operation workflow of the present utility model more, below utilize three kinds of storage cards of SD, Mini SD and MMC as the introduction of the utility model flow process, also can utilize the usefulness of this method as switching if having the storage card 320 of more different sizes in the card reading interface 110.Please refer to shown in Figure 5ly, it is the connection diagram of storage card in the utility model.
Supposing that when the SD card is selected the pin position for electronegative potential for the chip of first test storage card and SD be effective action, then is that the storage card of selecting 320 is sent the forbidden energy indication during noble potential.When measurement jig 300 is inserted card reading interface 110, measurement jig 300 can receive the switching command that notebook sends, select pin position (reduce current potential make its effective) so as to triggering chip in the SD card, make the SD card selected as this kind storage card 320 that detects usefulness.So after the test of SD card finished, notebook sent switching command again one time, and drew high the current potential of the chip of SD card being selected the pin position, made SD card forbidden energy.Then, after the switch unit 330 in the measurement jig 300 detected this variation, measurement jig 300 switched to the SPI pattern with the SD card.In this simultaneously, notebook and SD card then are to remain the SPI communication pattern.Notebook is selected the storage card 320 of time bout desire test again and is repeated the step of above-mentioned switching, test, communication and selection, until all storage cards 320 are all tested finish till.
The utility model provides a kind of measurement jig 300 of card reading interface 110, has the card reading interface slot of many specifications memory card interface in order to connection, can reduce the plug number of times of reading card interface slot.And send switching command by notebook, so as to selecting the memory card interface of institute's desire test.
Though the utility model discloses as above with above-mentioned preferred embodiment; yet it is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when can doing a little change and retouching, therefore scope of patent protection of the present utility model must be looked the appended scope that claim defined of this instructions and is as the criterion.
