Abstract

The present invention relates to a computer system which is separated from external devices and an input-output method thereof. A host is communicated with a network in a wired mode or a wireless mode. The I/O operation of the host on remote devices is redirected to external devices of a docking station. As a display, a main board and a small quantity of device interfaces are left, the volume of a computer host system is handy and smart. As a radio communication channel is arranged between the docking station and the computer host system, the computer host system can flexibly move in the wireless signal coverage area, and simultaneously an input-output device on the docking station can be used. The computer host system can be communicated with one or a plurality of docking stations. A plurality of computer host systems can be communicated with one stocking station or the docking stations, so that the device resources on the docking stations are fully utilized. The computer host system can be connected with Internet through a wireless network in the area which can not be covered by the wireless signals, and is communicated with one or a plurality of remote docking stations through the Internet to use the devices on the docking stations.

Description

The input output method that separates the computer system of setting with external unit

Technical field

The present invention relates to a kind of input output method of computer system, relate in particular to and a kind ofly connect main frame by wireless network and expand the computer system of docking station (abbreviation docking station) and the method that external unit carries out the data input-output operation, belong to field of computer technology with its input-output device.

Background technology

Because the function of computer increases, and the increasing gradually of computer peripheral kind, the external apparatus interface that computing machine carries often can not satisfy user's demand.So some computing machines have the expansion docking station now.This expansion docking station physically links together computer peripheral and main frame by the interface on it, this expansion docking station possesses a lot of external interfaces, comprise serial communication interface, parallel communication interface, USB (universal serial bus) (Universal Serial Bus, be called for short USB) interface and video graphics adaptor (VideoGraphies Adapter[Array], be called for short VGA) interface etc.When main frame linked to each other with docking station, each interface on the docking station can link to each other by interface corresponding on connector and the main frame.In this case, docking station itself not with the ability of external device communication, its effect just physics of host interface circuit is extended, so that realize being connected of interface and hardware device more easily.In the common physical connection mode, host entity and docking station entity must geographically be in same place, the main frame of connection docking station is light and thin notebook (Slim Notebook) computing machine and other suitable computing machine that moves normally, docking station is the expansion of the hardware capability of these main frames normally, but weight and volume all increases greatly after main frame and the docking station physical connection, reduces the dirigibility of main frame.The data that the introducing of wireless technology then is transformed into physical connection logic connect, as long as the scope that wireless network can cover, can both expand the function of main frame easily, combination by wireless network and cable network, the wireless network of two places is coupled together by cable network, this expansion can be reached near the immensity distance, simultaneously can pass through flexible net data sharing and secure access ability, the corresponding relation of docking station and main frame is extended to " multi-to-multi " by traditional " one to one ".

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of input output method that separates the computer system of setting with external unit, computer host system improves the dirigibility and the convenience of computer host system and external unit attended operation by setting up wired and passage radio communication with docking station.

Another object of the present invention is to provide a kind of input output method that separates the computer system of setting with external unit, computer host system can communicate with a plurality of docking stations, thereby utilizes the device resource on more docking stations.

In order to realize fundamental purpose of the present invention, its concrete method is:

A kind of input output method that separates the computer system of setting with external unit comprises at least:

Step 1: the remote equipment driver that runs on the computer host system is communicated by letter with remote equipment service routine corresponding with this program, that run on the docking station, send the input and output request to docking station, simultaneously output data is transferred to the remote equipment driver;

Step 2: the remote equipment driver will be asked and output data sends to the remote equipment service routine that runs on the docking station;

Step 3: run on the driver that remote equipment service routine on the docking station is transmitted to this input and output request and output data the docking station local hardware device;

Step 4: the driver of docking station local hardware device is transmitted to this input and output request and output data the hardware device of docking station this locality;

Step 5: the hardware device of docking station this locality is responded this input and output request and output data;

Step 6: the hardware device of docking station this locality is issued response data the driver of docking station local hardware device;

Step 7: docking station local hardware device driver is issued response data the remote equipment service routine that runs on the docking station;

Step 8: the remote equipment service routine that runs on the docking station is issued response data the remote equipment driver that runs on computer host system;

Step 9: the remote equipment driver that runs on computer host system is issued response data the application program that runs on computer host system.

In order to realize second purpose of the present invention, concrete method is: when the corresponding a plurality of docking stations of a computer host system or the corresponding a plurality of computer host systems of docking station, during the corresponding a plurality of docking station of perhaps a plurality of computer host systems, before communication, add the security mechanism of docking station for the computer host system authentication, the process authentication, docking station just receives the request and the data of this computer host system.

Disclosed computer system host and input output method compare with traditional computer system, its advantage is:

(1) owing to only stay the interface that is used to connect display, mainboard and small number of devices, what the volume of computer host system can be done is very nimble light and handy;

(2) owing to the passage that has radio communication between docking station and computer host system, computer host system can move in the wireless signal coverage easily and flexibly, still can use the input-output device on the docking station simultaneously;

(3) computer host system can communicate with one or more docking stations; Otherwise a plurality of computer host systems can communicate with one or more docking stations, thereby make full use of the device resource on one or more docking stations;

(4) computer host system is in the zone that wireless signal does not cover, computer host system also can be connected with Internet by wireless network, and communicate by Internet and long-range one or more docking stations, use the input-output device on the docking station.
