(Embodiment) In the following embodiments, the portable storage device with the prompt function of the present invention is applied to a flash drive having a flash memory as a data storage module and having a USB connector for the portable body. When the disc is inserted into the USB slot included in the host system, the contact condition can be detected to ensure that the data transmission between the host system and the flash drive is completed, thereby preventing data leakage. Occurs; however, it should first be noted that || Yes, the contact prompt function provided by the portable storage device with the prompt function of the present invention is not only applicable to the flash drive, and in general, the present invention is applicable to Portable storage devices that can exchange data with the host system through a USB transmission module, such as a mobile hard disk, a card reader, a digital camera, and a voice recorder, etc., to provide a connection between the devices and the host system. Detecting the connection between the host system and the host system, and providing a warning mechanism to prompt the user to prevent data leakage or undeliverable In this case, the portable storage device of the present invention can also be applied to the product testing process to test whether the contact state of the connection interface is normal. The first picture is a schematic diagram of a device architecture, which shows an internal structure of the application disk 10 and its connection with the host system 20, as shown in the figure, the pen drive 1 0 The external system group is provided with a USB specification connection module 1 1 for tying to a USB slot (not shown) included in the host system 20, so that the portable disk 10 can be formed with the host system 20 Electrically connected to perform a data transmission operation, the portable disk 10 includes an internal power

Voltage detection mode Group 1 7 and prompt module 1 8; when the user wants to transfer data between the flash drive 10 and the host system 20 (from the flash drive 10 to the host system 2 0 or from the host system 2 0 When the data is connected to the flash drive 1 0), it firstly aligns and connects the connection module 1 1 of the portable disk 10 into the USB slot on the host system 20, and at this time, the host system 20 Conductive pin 5 V (volts) and GND (G r 〇und grounding abbreviated) transmits a 5 V power supply to the internal body of the flash drive 10 to drive the flash drive 10 and simultaneously supply the flash drive 10 The power source, when the input power is supplied to the flash drive 10, the voltage detection module 17 immediately detects the voltage of the D + pin (P i η) contained in the data transmission module 14 . To determine whether the voltage of the D + pin exceeds 3 V, which is due to the conventional USB transmission interface module (not shown). The voltage of the D+ pin is about 2.96 V. When the USB transmission interface module is connected to the host system and the contact is bad, the voltage of the D+ pin will exceed 3 V. At the same time, the data transmission function of the USB flash drive is also invalidated. If the voltage detection module 17 detects that the voltage of the D + pin has exceeded 3 V, it will be the connection mode. The group 1 1 is caused by poor contact with the _ USB slot (not shown) included in the host system 20, and at this time, the voltage detecting module 1 7 驱动 immediately drives the prompting module 18 to generate a sound mode (also A warning message may be output for the vibration mode to inform the user that the connection between the portable disk 10 and the host system 20 is poorly connected, and the flash drive 10 must be re-inserted and reinserted into the host system 2 0 until The prompt module 1 8 no longer emits an audible warning message, and 遂 indicates that the flash drive 1 〇 is connected to the host system 20

Invention Description (6) Normal touch, at this time, the processing unit 15 can control the data storage module 16 and perform the message and command transfer operation with the host system 20 . FIG. 2 is a flow chart for illustrating the use of the prompting function of the present invention to detect that the contact with the host system 20 is abnormal until the warning message is issued. Step flow, as shown in the figure, firstly, the user inserts the connection module 1 1 included in the portable disk 10 into the USB slot included in the host system 20 to perform data transmission between the two. Then, the process proceeds to step S2. In step S2, when the flash drive 10 is inserted into the gB slot included in the host system 20, the host system 20 transmits a 5 V power supply to the flash drive 10 via the connection module 1 1 . The drive flash drive 10 operates, and then proceeds to step S3. In step S3, when an external power source is input to the flash drive 10, the voltage detecting module 1 7 immediately detects the current potential of the D+ pin included in the data transmission module 14 and then , and proceed to step S4. In step S4, the voltage detecting module 17 detects whether the potential of the D+ pin exceeds 3 V, and if so, proceeds to step S 5, and if not, represents the flash drive 10 and the host system 2 0 The link between the two is normal, there is no contact, no good situation occurs, and the work can be directly carried out for data transmission or file storage.

In step S5, the voltage detecting module 1 7 immediately drives the prompting module 18 to issue a warning message to inform the user that the connection between the portable disk 10 and the host system 20 is in poor contact. Transfer or file storage work.
