Embodiment
Referring to accompanying drawing 1, present embodiment is made up of host computer mainboard 1, data-interface expansion module 2, hard disk control module 3, power switching module 4, seven parts such as storage hard disk groups 5, system disk 6 and Switching Power Supply 7.
Data-interface expansion module 2, the serial hard disk interface number by expansion host computer mainboard satisfies the hard disk quantity that system's needs connect, and when host computer mainboard serial hard disk interface number during greater than connecing hard disk, hard disk can directly link to each other with the host computer mainboard; When the serial hard disk interface number is less than institute when connecing hard disk,, can be divided into a plurality of non-interfaces of working simultaneously to a serial hard disk interface by HF switch chip 2-1 (Fig. 2-1).2-2 can be connected to a plurality of SATA hard disks on the main sata port by serial ports multiplication chip, (this product now is in the sample stage as Sil3726SATA port multiplication chip (Fig. 2-2), estimate that the third quater in 2005 can volume production, price price $15/ sheet (ten thousand buyings), this chip is supported " the port multiplication standard 1.1 " in the SATAII standard, the employing bandwidth is divided equally, can be divided into 5 serial ports to a serial ports and work simultaneously.Can be divided into a plurality of non-interfaces of working simultaneously to a serial hard disk interface by data line 2-3 in parallel (Fig. 2-3) in the circuit board.
As shown in Figure 3, hard disk control module 3, RXD end and TXD end by hard disk control chip 3-1 (89C51 series monolithic), in parallel with the RXD of USB conversion chip 3-4 (CP2101) and RS-485 conversion chip 3-2 (SN75176) end and TXD end respectively, the switching of realization host computer mainboard communication interface and hard disk control module and to the control of hard disk operation.USB conversion chip 3-4 is connected with USB interface 3-5, and RS-485 conversion chip 3-2 is connected with RS-485 interface 3-3.
Power switching module 4 by the control signal of the 89C51 series monolithic in hard disk control module output, can be controlled the power supply of corresponding hard disk respectively through triode Q and relay J.
Storage hard disk groups 5 is made up of the series hard-disk of supporting hot plug, as Seagate cruel fish 7200.7.SATA hard disk, has adopted present up-to-date SATA V2.0 specification, and the hard disk power supply wiring also need be supported the power standard of series hard-disk.Storage hard disk quantity is by system's actual needs decision.
System disk 6, the independent operating work of starting shooting all the time, its interface and type can be chosen wantonly.As use the IDE hard-disk interface, then hard disk is also used the hard disk of ide interface; As using SATA serial type interface, then system disk is also used the serial line interface hard disk.
Switching Power Supply 7 is for total system provides the galvanic current source.
Principle of work of the present invention is: referring to Fig. 3 circuit theory diagrams: the hard disk control chip adopts the 89C2051 single-chip microcomputer, and each port designations meaning is:
The input of VCC DC voltage
The TXD serial data sends
The RXD serial data receives
XTAL1, the external crystal oscillator pin of XTAL2, when using the chip internal clock, this pin is used for external quartz crystal and trimmer; When using external clock, be used to connect the external clock pulse signal.
The host computer mainboard uses USB interface or RS-485 interface, but the two can only use one, if connect the USB mouth then can be the RS-485 mouth as the host computer external communication interface.Change serial port chip CP2101 conversion output rs 232 serial interface signal TXD by USB and link to each other with RXD with the TXD of 89C2051 single-chip microcomputer, make USB mouth and microcontroller serial port to exchange visits easily with RXD.By the SN75176 chip RS-485 mouth conversion output rs 232 serial interface signal TXD is linked to each other with RXD with the TXD of 89C2051 single-chip microcomputer with RXD, make RS-485 mouth and microcontroller serial port also can exchange visits easily.
Host computer also can use the RS-232 communication interface, just can interconnect and exchange visits with 89C2051 easily by level transferring chip MC1488 and MC1489.
When the host computer mainboard need be stored hard disk operation to certain, the host computer mainboard is given 89C2051 transmit operation instruction by USB mouth, RS-485 mouth or RS-232 mouth and communication protocol, 89C2051 by corresponding mouthful of line in 8 bidirectional interface lines of P1.0～P1.7 control peripheral triode Q and relay J and necessary hard disc data switch chip action, realizes the switch activated power supply that should store hard disk.
The required power supply of hard disk carries out switch control by relay J, because present series hard-disk only needs 5V and 12V voltage, relay J can select for use two disconnected two to open, or only two opens, and breaking can.If also need 3.3V voltage, can select three disconnected three relays of opening for use.The front end of relay preferably adds filter capacitor, and the rear end adds inductance, to improve the stability of power supply.
By software design, the computer system timing sends signal to 89C2051, and when system in case of system halt, 89C2051 will detect the signal that sends less than system, can hold the transmission Restart Signal to restarting of host computer by P3.4 mouth and the light surround idol circuit of 89C2051.As sending a telegram here again behind the system blackout, then P3.5 mouth and the light surround idol circuit by 89C2051 sends enabling signal to the start end of host computer.As the time of system's timed power on/off is issued 89C2051, then can realize system's automatic time switch machine.
Software flow pattern of the present invention, referring to Fig. 4:
At first, manual installation also is provided with the one-to-one relationship that each stores hard disk and data-interface, to each fdisk and format, on software, hard disk position and quantity are provided with simultaneously in advance, with unnecessary hard disk detection time after the operation of minimizing system.
For use HF switch chip, or the hard disc data line parallel, a serial hard disk interface is divided into a plurality of non-interface circuits of working simultaneously, when starting one of them hard disk, to close another hard disk earlier; To using the interface circuit of serial ports multiplication chip, can start any one hard disk and needn't close the hard disk of current operation earlier, and boot sequence can be arbitrarily.
Incoming call is restarted function: when the hard disk control chip never electricity hard disk control chip under the situation that electricity is arranged cross N after second (N can be that program is determined by writing the hard disk control chip) will start interface end to host computer and send enabling signal startup computing machine.
Anti-deadlock function: if the hard disk control chip is the signal of communication that receives host computer in the time in regulation, just do not restart, and host computer also will regularly be sent out some data useless to hard disk controller when not having Content of Communication, if and just can not be under the situation that master system crashes to hard disk control chip transmission data, hard disk control chip control Restart Signal controller is restarted host computer like this, certainly if shutdown or restart before will send instruction to following controller, so host computer just can not rerun this program till requiring him to move this program again to or control chip powered with different power supplys with switch chip.
