Description
Technical Field
The invention relates to the technical field of computer screen expansion, in particular to a method for automatically reducing the refresh frequency of an expansion screen based on a software type and a mouse pointer position.
Background
Computer screen displays are divided into four modes: a computer screen only mode, a copy mode, an expansion mode, and a second screen only mode.
Extension mode: the computer desktop is extended to the external screen, the extended desktop displayed by projection has no desktop icons and taskbar shortcut icons, and only a blank desktop can drag the content displayed on the computer screen to the projection screen for display, so that the area of the computer desktop is extended, and the multi-screen office study of a user is facilitated.
In the extended mode, the information to be displayed by the computer is displayed on the external screen through the data line, or the information to be displayed by the bluetooth is displayed on another computer or the notebook.
When the second computer or tablet is the projection extension screen of the first computer.
The first computer transmits the screen data display information to be expanded to the second computer in real time through Bluetooth through the projection expansion function, and the second computer decodes and restores the data information received by Bluetooth, then displays the data information on the screen of the second computer and refreshes the screen display in real time.
The current technical solution has the following drawbacks.
First, for some computers with lower overall configuration, when the projection expansion function of the computer is realized by transmitting data through bluetooth, the phenomenon of data loss occasionally occurs because the data transmission of bluetooth is not stable enough, and phenomena of unclear local display, dislocation and the like can occur on a second computer screen.
When static pages like PPT and Word documents are displayed on the second computer screen, the second computer screen does not need to update page information frequently, namely the first computer does not need to send new page information to the second computer in real time, so that the Bluetooth module of the first computer also does not need to send data information to the first computer in real time.
However, in the prior art, whether a static page that is static or a dynamic page that is changing is displayed on the screen of the second computer, the first computer always sends the page information processed by the system to the second computer in real time. This occupies the memory of the first computer, affects the operation speed of the first computer, and causes unnecessary power resource waste.
Disclosure of Invention
Aiming at the defects in the prior art, the method carries out annotation classification on the software installed by the user, and is divided into static software of which the interface does not need to be updated in real time and dynamic software of which the interface needs to be updated in real time. When the computer projection expansion function is used on the first computer to expand the first computer desktop to the second computer screen. The operating system of the first computer firstly accesses the local software labeling classification table to judge whether the screen display interface of the second computer is only displayed by static software. If the condition is met, continuing to judge whether the mouse pointer is on the screen display interface of the first computer or the screen display interface of the second computer. When only static software is displayed on the screen display interface of the second computer and the mouse pointer is on the screen display interface of the first computer, the operating system of the first computer of the user reduces the refreshing frequency of the screen display interface of the second computer. Therefore, occupation of the memory and the CPU of the first computer is reduced, the running speed of the first computer is improved, unnecessary data transmission of two computers is reduced, phenomena of data loss, unclear local display of a screen, dislocation and the like caused by data transmission are reduced, and the display quality of static interface information is improved.

Server side: firstly, a server-side software annotation classification table is established in a server-side database.
Then, manually or automatically labeling and classifying the software and the software version thereof on the market, and labeling as static software if the software interface does not need to be updated in real time; if the software interface needs to be updated in real time, the software interface is marked as dynamic software.
Server side software labeling classification table: different annotation classifications correspond to different software and different software versions.
The software labeling classification table in the database at the server side is continuously updated.
The program flow when the user side newly installs the software is as follows.
Step S11: when the user uploads new software to the computer, the computer operating system of the user sends the name and version number of the software newly loaded by the user to the server.
Step S12: the server side receives the software name and version number sent by the user and then accesses the server side software labeling classification table to judge the type of the software currently loaded by the user, then generates software type receipt information and sends the produced software type receipt information to the computer of the user.
Step S13: after receiving the software type receipt information generated by the server, the computer operating system automatically supplements the software name, version number and software type information newly installed by the user into the local software label classification table.
When a user uses the computer projection expansion function to expand the first computer desktop to the second computer screen on the first computer, the program flow is as follows.
Step S, 21: the operating system of the first computer of the user first accesses the local software labeling classification table to label the software types of the software running on the first computer and the second computer, and then step S22 is executed.
Step S22, condition 1: and judging whether the screen display interface of the second computer is only displayed by static software.
If the operating system of the first computer detects that the software displayed on the screen display interface of the second computer is static software, executing step S23 to judge the condition 2; otherwise, the process returns to step S21.
Step S23, condition 2: and judging whether the mouse pointer is on a screen display interface of the first computer.
If the mouse pointer is on the screen display interface of the first computer, step S24 is performed.
If the mouse pointer is on the screen display interface of the second computer, step S25 is executed.
Step S24: the operating system of the first computer of the user reduces the refreshing frequency of the screen display interface of the second computer, the refreshing frequency is reduced to a plurality of times per second, namely, the screen display interface information sent to the second computer by the first computer through the Bluetooth module is changed from initial real-time transmission to a plurality of times per second, and the screen display interface information sent to the second computer by the first computer operating system is changed from initial real-time processing to a plurality of times per second.
Step S25, the operating system of the first computer of the user refreshes the screen display interface of the second computer in real time, namely the first computer sends the screen display interface information of the second computer to the second computer in real time through the Bluetooth module, and the operating system of the first computer processes the screen display interface information sent to the second computer in real time.
Therefore, the method judges the specific positions of the software mark type and the mouse pointer displayed on the second computer on the screen display interface of the computer, and further determines whether to reduce the refreshing frequency of the screen display interface of the second computer.
The reduced refresh frequency here is multiple times per second; preferably, the refresh is performed once a second or once 30 seconds.
The bluetooth module may be replaced by a data line.
The method provided by the invention is also suitable for the display interface expansion by connecting the data line with the second computer screen.
The automatic labeling and classifying method is as follows.
Firstly, clicking buttons at each position of the software interface one by one through a recursion algorithm, and expanding menu interfaces at each level.
And then judging whether the expanded menu interfaces at all levels are static interfaces or not respectively. Respectively capturing images of the same interface in a preset time range, comparing the two captured images, and if the contents of the two captured images are changed, indicating that the interface is a dynamic interface; if the contents of the two screen shots intercepted before and after are not changed, the interface is indicated to be a static interface.
If any one of the developed interfaces in the software is a dynamic interface, the software is marked as dynamic software, and the recursion of the button menu at each position of the software interface is ended.
If and only if all of the expanded interfaces are static interfaces, then the software is marked as static software.

When the operating system of the server side automatically marks the software on the market or marks the software on the market manually, firstly detecting the current software name and the software version number thereof, and if the software and the software version number thereof are already stored in the database of the server side, the operating system or the manual does not mark the software with the version number any more. If the software and the software version number thereof are not stored in the database at the server side, the operating system or the operator identifies and judges the software type of the version number, if the software interface does not need to be updated in real time, the software is marked as static software, and if the software interface does need to be updated in real time, the software is marked as dynamic software. After the software is marked by the operating system of the server side, the operating system of the server side automatically generates marking classification information of the software, and then the name, the software version number and the marking classification information of the software are added into a software marking classification table of the server side.
The software annotation classification table in the server-side database is updated with updates of the software and version numbers thereof on the market.
The user terminal: when a user uploads new software to a computer, the computer operating system of the user sends the name and version number of the software which is currently and newly loaded to a server side, the server side accesses a software label classification table of the server side after receiving the name and version number of the software which is sent by the user so as to judge the type of the software which is currently loaded by the user, and then generates software type receipt information and sends the receipt information to the user side. After receiving the software type receipt information generated by the server, the computer operating system of the user automatically supplements the software name, version number and software type information newly installed by the user into the local software label classification table.
And each time the user installs a piece of software on the computer, the computer operating system of the user accesses the server to request to acquire the label classification information of the currently installed software, and then automatically inpainting the newly installed software information of the user and the label classification information of the newly installed software into the local software label classification table.

And then judging whether the screen display interface of the second computer is only displayed by static software.
If the operating system of the first computer detects that the software displayed on the screen display interface of the second computer is static software, then judging whether the mouse pointer is on the screen display interface of the first computer or the screen display interface of the second computer.
If the mouse pointer is on the screen display interface of the first computer, the operating system of the first computer of the user reduces the refreshing frequency of the screen display interface of the second computer, the refreshing frequency is reduced to a plurality of times per second, namely, the screen display interface information sent to the second computer by the first computer through the Bluetooth module is changed from initial real-time transmission to a plurality of times per second, and the screen display interface information sent to the second computer by the operating system of the first computer is changed from initial real-time processing to a plurality of times per second processing.
If the mouse pointer is on the screen display interface of the second computer, the operating system of the first computer of the user refreshes the screen display interface of the second computer in real time, namely the first computer sends the screen display interface information of the second computer to the upper surface of the second computer in real time through the Bluetooth module, and the operating system of the first computer carries out real-time processing on the screen display interface information sent to the second computer.
Therefore, the method judges the specific positions of the software mark type and the mouse pointer displayed on the second computer on the screen display interface of the computer, and further determines whether to reduce the refreshing frequency of the screen display interface of the second computer.
The reduced refresh frequency here is multiple times per second; preferably, the refresh is performed once a second or once 30 seconds.
The method provided by the invention is also suitable for the display interface expansion by connecting the data line with the second computer screen.
As shown in FIG. 2, when a user expands a first computer desktop to a second computer screen using a computer projection expansion function on the first computer.
If only static software is displayed on the screen display interface of the second computer, for example, when only static interfaces such as PPT and Word documents are static on the screen display interface of the second computer, the screen display interface of the second computer does not need to frequently refresh the static PPT and Word document information, that is, the first computer does not need to send new interface display information to the second computer in real time, the first computer does not need to send the new interface display information to the second computer in real time through the Bluetooth module, and the first computer operating system does not need to process the interface display information sent to the second computer in real time. Therefore, occupation of the memory and the CPU of the first computer is reduced, the running speed of the first computer is improved, unnecessary data transmission of the two computers is reduced, phenomena of data loss, unclear local display of a screen, dislocation and the like caused by data transmission are reduced, and the display quality of static interface information is improved.
When only static software is displayed on the screen display interface of the second computer and the mouse pointer is on the screen display interface of the first computer, the operating system of the first computer of the user reduces the refreshing frequency of the screen display interface of the second computer, and the refreshing frequency is reduced to a plurality of times per second.
When only static software is displayed on the screen display interface of the second computer and the mouse pointer is on the screen display interface of the second computer, the operating system of the first computer of the user refreshes the screen display interface of the second computer in real time.
