Embodiment
Below in conjunction with accompanying drawing exemplary embodiment of the present invention is described.In the accompanying drawing, identical parts are represented with identical label.
Fig. 1 shows the circuit block diagram according to portable hard drive of the present invention.Portable hard drive comprises hard disk main body 15 and usb 10, is provided with an electric capacity 13 between hard disk main body 15 and usb 10.Hard disk main body 15 comprises hard disk control circuit 151 and harddisk memory 152.This electric capacity 13 is a jumbo electric capacity, by discharge process, can provide a big starting current for portable hard drive.
Between usb 10 and hard disk main body 15, be connected with a trigger control circuit 12 and a switchgear 14 in turn.Switchgear 14 can be an electronic switch.Trigger control circuit 12 is used for providing a trigger pip at electric capacity after the 13 charging schedule times, and switchgear 14 receives this trigger pip, opens switch, thereby makes electric capacity 13 provide starting current to hard disk main body 15.
Wherein, electric capacity 13 is shunt capacitance, is provided with trigger control circuit 12 with being in parallel.The input end of electric capacity 13 is electrically connected to trigger control circuit 12, and output terminal is connected electrically between trigger control circuit 12 and the switchgear 14.
Fig. 2 is the workflow diagram according to portable hard drive startup method of the present invention.Below in conjunction with Fig. 2, the start-up course of the portable hard drive in the key diagram 1.
At first, the USB interface of portable hard drive is connected to corresponding USB interface on the computing machine.
Immediately, computing machine begins to be electric capacity 13 power supplies that trigger control circuit 12 picks up counting simultaneously.
After trigger control circuit 12 timing schedule time, finish timing, and a trigger pip is provided; Switchgear 14 receives this trigger pip, opens switch, makes electric capacity 13 discharges.
Portable hard drive powers on, and obtains a big starting current by the capacitance discharges effect.
In above example, add a large bulk capacitance 13 at the power interface place of portable hard drive, and mix relative trigger device control circuit 12.Like this, after passing through the USB line and PC link to each other, the portable hard drive of not being eager to start earlier, but give electric capacity 13 chargings earlier, and after electric capacity 13 is full of, start portable hard drive immediately, along with the starting current of portable hard drive is bigger, meeting drag down the voltage of USB interface.Because the characteristic of electric capacity is that voltage can not suddenly change, electric capacity 13 just discharges this moment.The electric weight of electric capacity 13 storage adds that the power supply of USB can satisfy the startup of portable hard drive, and the big I of capacitance is decided according to user's starting current size.
Need to prove that the timer time of trigger control circuit will be according to the electric capacity required time set that charges, the selection of electric capacity will be calculated according to the concrete starting current of hard disk.
Because the duration of charging of electric capacity 13 is Milliseconds, therefore can not bring the slow obvious sensation of hard disk startup to the user.
Fig. 3 shows according to computing machine of the present invention, and it comprises mainboard 21, and has USB interface 20.Mainboard 21 is provided with South Bridge chip 221.USB interface 20 is connected to this South Bridge chip 221.Also be provided with shunt capacitance 23 between USB interface 20 and South Bridge chip 221, this electric capacity 23 can provide big starting current for the various hot-plug equipments that comprise portable hard drive by discharge process.
The input end of electric capacity 23 is connected to the South Bridge chip 221 of mainboard 21, and output terminal is connected to USB interface 20.
Fig. 4 shows the workflow diagram according to portable hard drive startup method of the present invention.Below in conjunction with Fig. 4, the start-up course of the computing machine of portable hard drive in being connected to Fig. 3 after connection is described.
At first start computing machine.Then, computing machine is a capacitances to supply power, electric capacity is in is full of electricity condition.Then, portable hard drive is connected to USB interface of computer 20.Immediately, capacitor discharge provides big starting current by USB interface for portable hard drive.
Can know,, in some cases, also can correspondingly adopt other suitable hot-plug interfaces in above example, for example IEEE1394 interface etc. though all be to carry out equipment with USB interface to connect.
Can also know that though the Starting mode of portable hard drive has been described, principle of the present invention is same being suitable for for other need the hot-plug equipment of great start-up current in above example.
Although the present invention is illustrated with reference to accompanying drawing and preferred embodiment, obviously, for a person skilled in the art, under the prerequisite that does not deviate from the spirit and scope of the present invention, can make various changes and variation to the present invention.Various change of the present invention, the content that changes by appending claims and equivalent thereof contain.
