Abstract
The invention relates to a method for coupling a common SATA hard disk and a USB mobile hard disk. In the method, the common SATA hard disk and the USB mobile hard disk are coupled into an integer to be used as a second hard disk of a computer so as to enlarge the storage capacity of a system, support a hot plug and be used as a mobile hard disk. The system comprises a power supply circuit, a signal switching circuit, a hot plug circuit and a USB-to-SATA conversion circuit, wherein when the power supply circuit is used as the second hard disk, an SATA interface supplies a power supply of 5V, and when the power supply circuit is used as the mobile hard disk, a USB interface supplies the power supply of 5V; the signal switching circuit judges whether an SATA function or a USB-to-SATA conversion function is used or not through a detection circuit and shuts down the non-operative circuit to prevent mutual signal interference; the hot plug circuit notifies the GPIO of a southbridge and supports the hot plug function of the second hard disk; and the USB-to-SATA conversion circuit realizes the functions of the USB mobile hard disk.
Description
Technical field
The present invention relates to the computer hardware technology field, being specifically related to a kind of collection second hard disk and portable hard drive function is the convenient storage system of one.
Technical background
Information, information continue to increase, and computer hard disc also develops into a present hundreds of G from before several G, even go up T, and the capacity of single hard disk has been difficult to satisfy many users' demand, at will puts several high-definition movies, MP3 a lot of spaces that will account for.The user of at present a lot of desktop computers has disposed two hard disks or many hard-disk systems, and a lot of line notebook manufacturers have also released the large scale notebook computer of the two hard disks of configuration.While is copying data easily, and shifting also seems becomes more and more important.To domestic consumer, the built-in hard disk of computer can directly be taken out when portable hard drive usefulness, and it is very convenient just to seem, and has saved the expense that disposes another piece portable hard drive for the user.The demand of expanding system capacity had both been satisfied in the design of this programme, can provide Mobile Storage Function MSF easily again.
Summary of the invention
The purpose of this invention is to provide a kind of common SATA hard disk and mobile USB hard disk and unite the method that second hard disk uses of doing.
Method of the present invention realizes in the following manner, common SATA hard disk and mobile USB hard disk are integrated as second hard disk use of computing machine, to increase the memory capacity of system, support hot plug and do the portable hard drive use that system architecture comprises: power circuit; Signal switching circuit; Plug-and-play circuit and USB change the SATA circuit; Wherein:
Power circuit: when using, provide 5V power supply by the SATA interface as second hard disk; When using, provide 5V power supply by USB interface as portable hard drive;
Signal switching circuit: judge it is that the SATA function is being used by circuit for detecting, or USB changes the SATA function using, and closes idle that road simultaneously, signal does not disturb mutually;
Plug-and-play circuit: notify the GPIO of south bridge, support the hot plug function of second hard disk;
USB changes the SATA circuit: the function that realizes the USB portable hard drive.
The invention has the beneficial effects as follows:
(1) provide the expansion hard disk of second SATA interface for notebook or desktop computer, increasing the memory capacity of system, and support the hot plug function when using as second hard disk, as long as the user is click screen bottom-right " safe deleting hardware ";
(2) system supports the function of the portable hard drive of USB interface, can be used as portable hard drive and use in computer after pulling out, and makes things convenient for copy, the transfer of data, and two functions are integrated, and satisfy conveniently call data storage of user.
Description of drawings
Accompanying drawing 1:SATA signal switching circuit block diagram;
Accompanying drawing 2: overall system architecture figure.
Embodiment
With reference to accompanying drawing method of the present invention is done following detailed explanation.
System architecture of the present invention consists predominantly of a SATA male (being used to connect the female of mainboard), a SATA female (being used to connect the SATA hard disk), and the SATA Switch (switch) of an alternative and USB change the SATA chip.As shown in Figure 1, when using, close the SATA1 bus, SATA2 is linked to each other with SATAO by enable signal control SATA switch as second hard disk; When using as portable hard drive, switch just closes SATA2, and SATA0 is linked to each other with SATA1, and the effect of SATA Switch is that control three road SATA signals work alone, and does not disturb mutually.
The principle of work of this system is described below in conjunction with Fig. 2:
One, when using as second hard disk:
Ground connection Pin on the SATA male just sends SATA2_IN# signal (effectively low) to EC (embedded controller), and it is next that EC sends out second hard disk reeve of SATA2_EN notice south bridge then, and opening 5V voltage simultaneously is the hard disk power supply, is that SATA2 links to each other with SATA0 at this moment.
Two, when as portable hard drive:
When detachment system used as portable hard drive, the 5V voltage of USB Connector offered hard disk on the one hand, produced 3D3V by voltage conversion circuit on the other hand, changeed the chip power supply of SATA for USB.Be that SATA1 links to each other with SATA0 at this moment.So the portable hard drive function can realize.
Claims (1)
1. the method for common SATA hard disk and the coupling of mobile USB hard disk, it is characterized in that, common SATA hard disk and mobile USB hard disk are integrated as second hard disk use of computing machine, to increase the memory capacity of system, support hot plug and do the portable hard drive use, system architecture comprises: power circuit; Signal switching circuit; Plug-and-play circuit and USB change the SATA circuit; Wherein:
Power circuit: when using, provide 5V power supply by the SATA interface as second hard disk; When using, provide 5V power supply by USB interface as portable hard drive;
Signal switching circuit: judge it is the user mode that SATA function or USB change the SATA function by circuit for detecting, close idle that road, avoid the mutual interference of signal phase;
Plug-and-play circuit: notify the GPIO of south bridge, support the hot plug function of second hard disk;
USB changes the SATA circuit: the function that realizes the USB portable hard drive.
