Embodiment

The present invention is described in further detail below in conjunction with accompanying drawing and specific embodiment:

Sees also Fig. 1, in the EFI of client computer, be provided for the client-side program that client computer carries out remote detection and control, and client-side program is set to prior to os starting, after client computer starts, carry out following steps:

Step 1: described client-side program starts, and determines whether that according to user's input and system's detection judgement needs carry out remote detection and control to client computer; If desired client computer is carried out remote detection and control, execution in step 2, otherwise, execution in step 3;

Performing step of the present invention is divided into four-stage: the one, and deployment phase, the 2nd, configuration phase, the 3rd, the unloading phase, the 4th, the operational administrative stage.

Deployment phase mainly was before computing machine dispatches from the factory, perhaps in the process of BIOS of upgrading computing machine, the EFI of client software, client software trigger and client computer is integrated, and can UNICOM on network the machine of client and server end, to guarantee that client software can correctly have access to server software in the process of implementation.The process of deployment phase is: use the FIRMWARE strapping tool of EFI, the FIRMWARE of client-side program and client software trigger and EFI is packaged in together, form an independently file.And use the programming instrument of BIOS ROM that this document is written among the BIOS ROM.So just finish the deployment of client software.The user need use of the present invention the time, the server that can own independent dispose a computing machine as LAN (Local Area Network) is used to detect and control the online computing machine that connects of this local, and at this build-in services device end software above computing machine; The user also can be directly the server of the site for service of computer vendors as own computer access.This method realizes that by the network ways of connecting program of client and server end is connected, and server can be simultaneously carries out remote detection and control to the computing machine of a plurality of clients.

The BIOS rom chip is the storer that is used for storing BIOS on the mainboard, and the type can adopt diversified chip, as ROM, EPROM, EEPROM, FLASH ROM etc.

Configuration phase mainly is that the user is when using this computing machine for the first time, perhaps when using client-side program and server to communicate for the first time, or server and client side's IP address need be configured server and client side's IP address when changing.Simultaneously, in client-side program the inside, the IP address that can use the IP address dynamic-configuration agreement of server end to obtain client also can be provided with the client fixed IP addresses.

Client-side program comprises client software trigger, client-side management subroutine, client renewal (upgrading) subroutine and client remote maintenance subroutine.

The unloading phase major function be to activate client-side program, and be connected with server program.During computer starting, the client software trigger moves automatically, and at first whether the client software trigger detects and to be connected required procotol with server and to load, if less than loading, then this procotol is loaded in the internal memory.

Determine whether that according to user's input and system's detection judgement needs carry out remote detection to client computer and control comprises following concrete steps then:

Step 11: described client-side program judges in a stand-by period of setting whether user key-press is arranged, if any, execution in step 2, otherwise, execution in step 12;

Step 12: if the stand-by period of setting do not arrive, execution in step 11, otherwise, execution in step 13.

The client presses particular key according to screen prompt and can enter client-side management subroutine, client renewal (upgrading) subroutine and client remote maintenance subroutine at this moment, be that the client software trigger judges in a stand-by period of setting whether user key-press is arranged, this moment, the user in time pressed this particular key, had just entered client-side management subroutine, client renewal (upgrading) subroutine and client remote maintenance subroutine.Client-side program can if connect normally, just show and can correctly use the function of remote detection and control according to the IP address that configures from the remote server that is dynamically connected.

The unloading phase another Starting mode be exactly under the situation that can not guide appears in operating system, break down as operating system itself collapse, hard disk etc., the client software trigger will call the client-side management subroutine automatically, client is upgraded (upgrading) subroutine and client remote maintenance subroutine, and concrete steps are as follows:

Step 13: whether can client-side program detecting operation system guide with physical hard disk normal;

Step 14: described client-side program detects that operating system can not guide or physical hard disk damages execution in step 2, otherwise execution in step 3.

Please refer to Fig. 2, in the start-up course of EFI, before the boot of call operation system, the client-side program that calls on the EFI triggers software; Client-side program triggers software and will press certain particular key execution client-side management subroutine, client renewal (upgrading) subroutine and client remote maintenance subroutine to user prompt on display screen then, client-side program triggers software and judges in a stand-by period (for example 2 seconds) of setting whether user key-press is arranged, if this moment, the user pressed this particular key in 2 seconds stand-by period, will start client-side management subroutine, client renewal (upgrading) subroutine and client remote maintenance subroutine; If in 2 seconds stand-by period, do not have press key message sent by user, whether can client-side program just begin the detecting operation system and guide with physical hard disk and damage.When damaging and can not guide may appear in operating system, perhaps physical fault etc. appears in hard disk, cause the operating system can't normal boot, client-side program triggering this moment software will trigger automatically and carry out the client-side management subroutine, client is upgraded (upgrading) subroutine and client remote maintenance subroutine, and gives administrative center the problem Trouble Report.

The operational administrative stage is remote detection and a control function of finishing client on client.There is dual mode operational phase: first kind of mode is the various concrete functions of the manual button operation of user.Client software will show that friendly prompting interface allows the user finish concrete remote detection and control function in this case.The second way is this computing machine nobody operation, and be after operating system can not start, to enter under the situation of client-side program, at the enterprising line operate of server, finish the function of long-range various telemanagement, upgrading and maintenance to client computer by the keeper.

The client-side management subroutine, be used for the information of computing machine is gathered and detected, the request of response server end supervisory routine, the information of gathering and detect is sent to the server end supervisory routine, and the control command that sends according to described server end supervisory routine, carry out the operation of control command indication, control command comprises the order of shutdown command, computing machine reset command and/or shielding mainboard parts.

Client is upgraded (upgrading) subroutine request server end software administration center and is started server end remote upgrade software, required upgrading software is downloaded to from server end on the hard disk of client computer or on the BIOS ROM, client is upgraded (upgrading) subroutine and is used to carry out the renewal of the renewal of described EFI, described client-side program and the renewal of other programs.

Client remote maintenance subroutine is after the remote maintenance PROGRAMMED REQUESTS order that receives server end, control computer is carried out described client remote maintenance subroutine, carry out the system diagnostics of client computer response, after executing, the result is fed back to server.

It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
