Description

Based on Windows operating system to the disposal route of the input of multichannel external unit and system
Technical field
The present invention relates to multimedia technology field, relate in particular to based on Windows operating system the disposal route of the input of multichannel external unit and system.
Background technology
The computer server that Windows operating system has been installed is being accepted the operation requests of the external unit of a plurality of terminals (as keyboard, mouse, joystick etc.) or computer server is local while connecting a plurality of external unit, can not distinguish and record the operation that in same class external unit, specifically which external unit application programs is carried out.Such as, one station server has connected a plurality of mouses (including Line Mouse, wireless mouse, contact control mouse, Rocking-bar mouse etc.) in this locality, use these mouses to operate simultaneously, server can respond all operations, but server is mixed and disorderly unordered to the result of the operation of each external unit.
As shown in Figure 1, be the Message Processing schematic diagram of prior art peripheral equipment when the local access server executable operations, in Fig. 1: external unit 1,2 ..., N, comprises keyboard, mouse, joystick etc.The external unit access port that server provides, can be USB interface, can be also PS/2 interface.External unit inserts interface first, and server need to be installed respective drive, can be that USB drives, and can be also that PS/2 drives; As long as such external unit is installed and is overdrived at this interface, access again afterwards, not needing again to install driving can directly use.The operation descriptor corresponding to all operations of external unit, through interface, pass to corresponding driving, by driving, operation descriptor is resolved to operation instruction information, then send to middleware, by all operation instruction information of middleware processes, middleware can be DInput.dll/user32.dll.In Fig. 1, USB interface, PS/2 interface, USB drive, PS/2 drives and middleware is all arranged in server.
Server receives the operation descriptor that peripheral equipment of terminal sends, corresponding driving resolves to operation instruction information by this operation descriptor and sends to middleware, unified operation instruction information corresponding to each external unit of preserving of middleware, but middleware is just according to the unified operation instruction information that receives, preserves external unit of time sequencing, cannot distinguish each operation instruction information and be which external unit send, for the operation instruction information of which application program.When application program need to be obtained operation instruction information (middleware passive mode), or when middleware sends to application program (middleware active mode) by operation instruction information, application program is according to the order of the operation instruction information of preserving in middleware, obtain successively each operation instruction information, even if this operation instruction information is not for this application program, because server cannot be distinguished the operation instruction information of each application program, application program also can only be obtained this operation instruction information, thereby causes the disorderly operation of application programs.
According to above-mentioned this locality, be connected with after the server of a plurality of external units the Message Processing flow process of executable operations known, for same station server, when this server connects a plurality of terminals by network mode, when each terminal connects corresponding external unit, the operation descriptor of each peripheral equipment of terminal sends to server by network, server receives after operation descriptor, operation descriptor is resolved to corresponding operation instruction information, follow-up processing procedure is identical for the control procedure of locally-attached external unit with server.Therefore when a plurality of terminals are connected with server by network, server also can, owing to can not distinguishing the input of each peripheral equipment of terminal, cause the disorderly operation to each end application.
Because server in the prior art cannot be simultaneously provides service for the input of a plurality of external units, for fear of maloperation, a plurality of servers can only be set, the request of a set of external unit of each server process.But the method has been wasted a large amount of resources, cannot meet large-capacity user group's demand.
