Abstract

The utility model relates to a mobile hard disc system with data transmission and data clone functions. The mobile hard disc system comprises a source hard disc, a target hard disc and a hard disc data conversion controller, wherein the hard disc data conversion controller comprises a USB (universal serial bus) interface, an eSATA (external serial advanced technology attachment) interface and three SATA data transmission ports, and the source hard disc and the target hard disc are respectively connected with one of the SATA data transmission ports. The mobile hard disc system can directly completely copy data of the source hard disc and the target hard disc without communicating with a computer, can still copy data in an off-line state, and simultaneously supports hard disc data communication with IDE (integrated development environment) or SATA various interfaces; in addition, the hard disc data conversion controller is connected with a quick copy functional button, the hard disc cone function can start after the quick copy functional button is pressed down, and the hard disc data conversion controller is connected with a hard disc state indication lamp or a liquid crystal display screen can indicate the state of a hard disc.

Description

A kind of portable hard drive system with data transmission and data clone function

Technical field

The utility model relates to electronic circuit, particularly a kind of hard disc data transmission circuit system.

Technical background

Along with popularizing fast of computer; Lot of data in the usual use of computer, can occur and need storage; Portable hard drive has obtained using widely under this application prospect as a kind of light and storage facilities high power capacity, in the usual use of computer, runs into the situation that needs refitting system or data backup through regular meeting, need use the mode of CD to install for the installation of system at ordinary times or adopts software to do mirror image; Likewise; When usual data backup, also need could realize, and computer generally adopts USB interface to carry out data transmission now through computer, but with respect to the SATA host-host protocol speed that has hard disk now; Its transmission speed is still for slower, all more consuming time and complicated operation with above these modes.

The utility model content

The utility model technical matters to be solved be overcome the computer delivery means of prior art in the middle of need adopting can copies data to target hard disk; Provide a kind of hard disk still can copies data under the situation of off line, need not to connect the system of computer, support IDE or SATA hard disk off line copy simultaneously.

A kind of portable hard drive system with data transmission and data clone function; Comprise source hard disk, target hard disk and hard disc data switching controller; Described hard disc data switching controller comprises USB interface, eSATA interface and three SATA data transmission port, and described source hard disk is connected a described SATA data transmission port respectively with target hard disk.

Described hard disc data switching controller connects quick copy function key, connects disk state pilot lamp or LCDs indication disk state simultaneously.

Source hard disk and target hard disk can be SATA interface or ide interface, and described SATA data transmission port directly is connected with the hard disk of SATA interface or changes the IDE controller through SATA and is connected with the hard disk of ide interface.

This novel beneficial effect is: it need not to connect computer also can be directly to source hard disk and target hard disk data integrity copy; Still can copies data under the situation of off line; Support the hard disc data communication of IDE or SATA multiple interfaces simultaneously; And the hard disc data switching controller is connected with a quick copy function key, can start the hard disc cloning function after pressing this function key, and the hard disc data switching controller connects the state that disk state pilot lamp or LCDs can be indicated hard disk.

Description of drawings

Fig. 1 is that the system of the utility model connects synoptic diagram;

Fig. 2 is that SATA changes the chip of IDE controller and the CC figure of peripheral signal wire thereof;

Fig. 3 is the chip of hard disc data switching controller and the CC figure of peripheral signal wire thereof;

Fig. 4 is the CC figure at SATA, ESATA and USB interface place;

Fig. 5 is the CC figure of disk state pilot lamp.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1; A kind of portable hard drive system with data transmission and data clone function; Comprise source hard disk, target hard disk and hard disc data switching controller; Described hard disc data switching controller comprises USB interface, eSATA interface and three SATA data transmission port, and described source hard disk is connected a described SATA data transmission port respectively with target hard disk.

Further above-mentioned each interface and controller are narrated, described hard disc data switching controller with JM352U as chip, described SATA change the IDE controller with JM20330 as chip.Like Fig. 2, shown in Figure 3; JM352U is responsible for data transmission or hard disc data off-line state under the clone of computer with portable hard drive; It comprises the CC of various functions, and computer uses usb data passage or ESATA interface channel to carry out data transmission down with the data transmission state of portable hard drive, and JM352U has 3 SATA data channel in addition; Its segment signal line connects and combines Fig. 4 and shown in Figure 3, and Fig. 5 illustrates the signal wire annexation of disk state pilot lamp and chip.

Can learn that by above structure described hard disc data switching controller is supported in to be realized under the situation that does not connect computer copying the data integrity of source hard disk to target hard disk.
