Abstract
A kind of application method based on Pos machine in KVM desktop virtualization, comprising the following steps: 1) by Pos thermomechanical components installation kit, Pos thermomechanical components are installed in virtual desktop；2) principle is redirected by USB, the Pos machine for turning USB interface using string is successfully mapped into virtual desktop；3) the third-party application software for using Pos machine, uses Pos machine.The data requested Pos machine are intercepted, will be sent using disposable repeatedly to Pos machine request data, and so that time delay be reduced, reach and use Pos machine in virtual desktop.Pos thermomechanical components are driven by Windows, in the request data of virtual generator terminal monitoring Pos machine.It is first that data temporary cache is internal to driving by the driving of invention when Pos machine sends command request, until the true Pos machine of Thin clients generator terminal is disposably being sent for the data of request by network when being completely received the data of this request.
Description
Technical field
The invention belongs to desktop virtual application technical fields, design cloud computing, virtualization technology, and in particular to one kind passes through
For traditional USB redirect principle processing Pos machine data algorithm optimization, facilitate Pos machine third-party application based on KVM desktop
The application method of Pos machine in virtualization.
Background technique
In existing virtualization desktop, the branch of Pos machine common interfaces serial ports is lacked due to local thin passenger plane using Pos machine
It holds, often in use, needing to turn USB line by string, uses Pos machine using usb mode, then redirected by USB
Mode is redirected in virtual desktop and uses.In virtual desktop, accessed equipment using the plug-in unit that Pos machine manufacturer carries,
It is usually all normal in simulation test since Pos machine itself is the operation system that will not connect bank in analogue data.But
It is that, due to mapping principle and the network of itself, will lead to request Pos machine data delay when connecting upper real operation system and become
Greatly, directly refuse inside Pos machine.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, a kind of Pos thermomechanical components are invented, by Pos thermomechanical components, are solved in KVM
The deficiency applied in desktop virtualization using Pos machine, Pos thermomechanical components are the data requested with the interception Pos machine of software realization, will
It originally needs by repeatedly to Pos machine request data process, being handled using Pos machine is disposably sent to, to reduce repeatedly number
According to the brought network request time is requested, the time delay when processing of Pos machine is reduced, reaches and uses Pos in KVM virtual desktop
Machine, Pos thermomechanical components are driven by Windows, in the request data of virtual generator terminal monitoring Pos machine.When Pos machine sends command request
When, it is first that data temporary cache is internal to driving by the driving of invention, until when being completely received the data of this request,
The true Pos machine of Thin clients generator terminal is disposably being sent by the data of request by network.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of application method based on Pos machine in KVM desktop virtualization, including this following step:
1) by Pos thermomechanical components installation kit, Pos thermomechanical components installation kit carries out processing point for analyzing Pos machine data, to data
Pos thermomechanical components are mounted on Windows system by analysis, and wherein the component installation kit includes the driving of Pos machine serial monitoring, Pos machine string
Pos thermomechanical components are installed in virtual desktop by slogan detection module；
2) principle is redirected by USB, and by each built-in virtual USB master controller driving of virtual desktop and client
(Host Driver) realizes that USB host controller under original physical drove zooms out, and the corresponding true USB device driving peace of equipment
It fills and operates in virtual desktop, the driving of virtual USB host controller interacts with virtual desktop, in this way in virtual machine
For USB device driving, controlled equipment can't be perceived actually in distal end, Pos machine application is just reset using USB
To method, first it is the Pos machine of serial ports type by interface type in FTP client FTP, USB line is turned by string, is converted to interface class
Type is USB, and the Pos machine of USB interface is successfully mapped into virtual desktop；
3) the third-party application software for using Pos machine, uses Pos machine.
The beneficial effects of the present invention are:
Pos machine itself is the equipment of a serial ports, in virtualization desktop application, since local thin client lacks hardware string
Mouthful, so desktop in use, must turn the apparatus assembly that usb line is converted into USB Type by going here and there, then passes through
The mode of USB port mapping is mapped into virtual desktop and is used, using mapping mode, by network increase data when
As a result ductility will lead to Pos machine, not be available in virtual desktop.Through the invention, the data of Pos machine will be sent to,
It is intercepted in virtual desktop, will need to be performed in multiple times operation Pos machine request data, be converted into once sending the data to
Pos machine is finally reached in virtual desktop to reduce the time delay of network data request packet, is carried out business using Pos machine and is done.
Detailed description of the invention
Fig. 1 is the principle of the present invention flow chart.
Specific embodiment
The present invention is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, a kind of application method based on Pos machine in KVM desktop virtualization, comprising the following steps:
1) by the Pos thermomechanical components of invention, Pos thermomechanical components are installed in virtual desktop；
2) principle is redirected by USB, the Pos machine for turning USB interface using string is successfully mapped into virtual desktop；
3) the third-party application software for using Pos machine, uses Pos machine.
Pos thermomechanical components are applied to using Pos machine and carry out data to virtual Pos machine to being mapped to string and turn USB to Pos machine mode
Flow direction processing.By using the mode of invention, it joined Pos thermomechanical components in original data flow, by Pos machine practical operation
The mode of multiple request data is handled and is completely requested to be primary, sends primary complete request of data, and purpose reduces multiple grasp
Make, the network data that centre generates requests time delay, reaches in virtual desktop application, carries out business processing using Pos machine.
