As shown in Fig. 1, in the first embodiment of the present invention, the mobile storage device in this embodiment is a mobile hard disk. The mobile hard drive includes:

A hard disk, most of the current hard disk can achieve head berth technology;

a hard disk controller connected to the hard disk, the hard disk controller is used to convert the communication protocol, Is an important part of the traditional mobile hard disk;

A USB interface to the hard disk controller communicates with the computer using the standard USB protocol.

The above is the basic structure of the traditional mobile hard disk. In this structure, the mobile hard disk further includes a sensor for monitoring the state of the hard disk in the working mode, the sensor is an attitude sensor; and an inductive signal processor connected to the sensor; There is also a hard disk command module connected to the sensing signal processor, wherein the hard disk command module stores the posture data signal and the matching data corresponding to the control of the hard disk operation.

When the mobile hard disk is working normally, the attitude sensor inside the mobile hard disk is in working state:

1), when the attitude sensor will monitor the state of the mobile hard disk, and send the data signal to the sensing signal processor;

2), the sensing signal processor receives the signal, analyzes and calculates it, and how to analyze and calculate the sensing signal processor, because each sensing signal processor may have functional nuances, for better disclosure The technical solution of the present invention is described by using an example of the working principle of the inductive signal processor commonly used in the art: the sensing signal processor compares the signal value at the moment with the signal value of the set previous monitoring period. According to the result of the comparison, it is determined whether to send an instruction to the hard disk command module, and which instruction is sent; for example, we set the monitoring period to 0.5 seconds, when the mobile hard disk suddenly shakes, the sensing signal processor receives the gesture. The signal sent by the sensor is processed to obtain a state value a in the period, and the value a is compared with the value b of the motion state signal recorded in the previous cycle, that is, 0.5 seconds before, and the comparison value is obtained. c. Determine whether to send an instruction to the hard disk command module according to the comparison value c. The manufacturer can customize a reference value d. When the comparison value c is greater than or less than the reference value d, the state of the mobile hard disk is defined as a normal working state. When the value c is greater than the reference value d, the state in which the mobile hard disk is located is defined as the state in which the operation needs to be changed. For example, the move is hard When the disk is shaking, set the amplitude of 10 cm to the distance that the hard disk does not change, and the moving hard disk needs to T seconds in the range of 10 cm, then the mobile hard disk is in the range of 10 cm and just happens. The moment of T seconds is considered to be the state critical moment of changing operation, and the time greater than or equal to the critical moment is to change the operating state. The moment less than 10 cm or less than τ seconds is considered to be a normal working state, in close proximity. A time when 10 cm or about τ seconds is defined can be defined as a state in which a change operation is about to occur.

3), if the comparison value c calculated by the sensing signal processor is less than the reference value d at this time, that is, the mobile hard disk is in a normal working state, the sensing signal processor does not perform an action;

4), if the comparison value c calculated by the sensing signal processor is greater than or equal to the reference value d, that is, the mobile hard disk is in need of changing the working state, the sensing signal processor sends an instruction to the hard disk command module, Here we can define the instructions to stop the hard disk work;

5), the hard disk command module executes the stop hard disk work instruction sent by the induction signal processor, the hard disk realizes the magnetic head berth, and the magnetic head returns to the parking area and locks within several tens of milliseconds;

6) When the mobile hard disk is restored to the normal working state, that is, when the mobile hard disk stops shaking, the sensing signal processor can send a startup work command to the hard disk command module, and the hard disk executes the start working command, so that the hard disk is powered on again to perform normal work.

As shown in Fig. 2, it is a second embodiment of the present invention. The embodiment is a mobile hard disk, and the difference from the first embodiment is mainly that a USB hub and a USB interface controller are added, and the USB interface is connected; the sensing signal processor is connected to the USB interface controller, and the USB interface controller is connected to the USB. The hub, meanwhile, the hard disk controller is also connected to the USB hub. Due to the existence of a USB hub, the operating system of the computer that transmits data to the mobile hard disk considers that there are two devices connected thereto. One device is actually: a sensor, an inductive signal processor connected to the sensor, and a USB interface controller. The other device is actually: hard disk controller and hard disk. In this way, the sensing signal processor can timely and effectively transmit the status signal of the mobile hard disk to the signal obtained by the sensing signal processor through the USB interface controller, and then send the signal to the computer operating system through the USB hub without Limited by other channels, so that The user knows what state the mobile hard disk is in.

If the mobile hard disk is in an intermediate state, that is, when the mobile hard disk is about to be in an abnormal working state, the sensing signal processor sends a signal to the computer through the USB hub, and the computer receives the signal to change the value in the corresponding register. When the computer queries the value in the next time period, a warning message is displayed on the display on the computer or the computer speaker emits an alarm sound.

If the state of the mobile hard disk needs to be changed, the sensing signal processor sends a signal to the computer through the USB hub, and the computer receives the signal to change the value in the corresponding register, and the computer queries the value during the current time period. At the same time, a warning message is displayed on the display on the computer or the computer speaker emits an alarm sound. At the same time, the sensing signal processor sends a stop operation command to the hard disk power supply switch, so that the hard disk realizes the magnetic head berth and protects the hard disk.

When the mobile hard disk is no longer in a shaking state, the sensing signal processor immediately sends a startup work command to the hard disk command module, and the hard disk command module sends a start command to the hard disk, and the mobile hard disk can continue to be used normally.

As shown in FIG. 3, the third embodiment of the present invention differs from the above embodiment mainly in that the hard disk controller module is controlled by the hard disk controller, that is, the sensing signal processor is not directly connected to the hard disk command module, that is, Directly responsible for controlling the hard disk, but through the hard disk controller connected to it, the hard disk controller controls the operation of the hard disk, and controls the hard disk. When the sensing signal processor sends information to the hard disk controller, the hard disk controller receives an instruction to control the hard disk command module.

As shown in Fig. 4, it is a fourth embodiment of the present invention. This embodiment is a video player, and the display and display controller on the video player can be used for alarms. The display screen is connected to the display controller, and the display controller is connected to the sensing signal processor. The display controller receives and processes the signal sent by the sensing signal processor, and sends the processed status information reflecting the movement storage device to the display. On the screen, notify the user that the mobile storage device is What kind of state. For example, when the hard disk in the video player is in a dangerous shaking state, the sensing signal processor immediately sends a stop operation command to the hard disk power supply switch; meanwhile, the sensing signal processor sends a signal to the display controller, and then the display controller displays The screen sends the message. When the dangerous state of the hard disk in the video player is released, the sensing signal processor immediately sends a resume working instruction to the hard disk command module to continue the working of the hard disk.

In addition, the alarm function in this embodiment can also be completed/implemented by the speaker and the speaker controller. The sensing signal processor sends the signal to the speaker controller, and the sound signal is sent to the speaker through the analysis and processing of the speaker controller, and a prompt sound is generated to achieve the purpose of letting the user know the state of the video player.

The data transmission protocols of existing external mobile devices are commonly used as USB interfaces and SATA interfaces. It can also be a 1394 interface, a serial/parallel interface, or a network cable interface.
