Specific embodiment
The core of the application is to provide a kind of touch-control system and its main control device and a kind of recovery of touch screen failure
Method and apparatus, to be effectively prevented from the loss of touch screen data when solving touch screen Its Failures, it is ensured that work is just
Often, sustainable operation, and then improve treatment effeciency and user experience.
In order to which technical solutions in the embodiments of the present application is more clearly and completely described, below in conjunction with this Shen
Please attached drawing in embodiment, technical solutions in the embodiments of the present application is introduced.Obviously, described embodiment is only
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
The embodiment of the present application discloses a kind of restoration methods of touch screen failure, and shown referring to Fig.1, this method mainly includes
Following steps:
S11: the interface that is connect with the touch panel of touch screen of detection whether communication failure；If so, into S12.
S12: the interface that control is connect with touch panel resets, to restart touch panel.
Specifically, touch screen generally comprises the display panel with interface display function and the touching with touch-control input function
Touch panel.Display panel and touch panel are respectively provided with independent interface, wherein the interface of display panel is used to be display panel
Electricity and transmitting display data are obtained, and the interface of touch panel is then used to obtain electricity for touch panel and transmits touch data.Generally,
The interface of touch panel concretely USB interface meets HID (Human Interface Device, human interface device) association
View, and can support hot plug.
Since display panel and touch panel are actually individually powered and transmit data, it is provided herein
Touch screen failure restoration methods, after detecting that communication failure occurs for the interface that connect with touch panel, not as existing
Entire touch screen even host equipment is all subjected to power-off restarting like that in technology, and merely by will be connect with touch panel
Interface reset, only touch panel is restarted, to eliminate the influence to touch panel such as electrostatic.Only due to touch panel
It is that will not influence display panel, therefore only restarting for touch panel will not influence touch screen for carrying out touch-control input
Normal display and operation, more will not influence the application program being currently running in host equipment.
Wherein, when carrying out communication failure detection to the interface that connect with touch panel, described communication failure include by
Communication failure caused by the influence of electrostatic or electromagnetic interference or signal error to touch panel.And connect in control and touch panel
It, specifically can be by the way of voltage amplitude, it is possible thereby to realize the power-off restarting of touch panel when the interface connect is resetted.
The restoration methods of touch screen failure provided herein are connect by detecting with what the touch panel of touch screen was connect
Mouthful whether communication failure；If so, the interface that control is connect with touch panel resets, to restart touch panel.As it can be seen that this Shen
Please provided by touch screen failure restoration methods, restarted particular by the touch panel to touch screen and solve to touch
Its Failures.Since without restarting to the display panel of touch screen, display panel can still be worked normally, i.e. this Shen
The system operation and display that please will not influence touch screen, effectively prevent the loss of touch screen data, more will not influence host
The application program being currently running in equipment, to ensure normal, the sustainable operation of customer service, improve treatment effeciency and

Certain equipment are additionally provided with status register corresponding with interface, then at this time can be straight for updating the communications status of record interface
The corresponding status register of inquiry is connect to be judged.
In the above content, as a kind of specific embodiment, obtaining external equipment information includes:
The data file of each external equipment in polling system bus；Obtain external equipment information.
Specifically, described control bus is software control bus, such as HID control bus (meets the soft of HID protocol
Part control bus).Traversal reads the data file of all external equipments in bus, therefrom obtains each external equipment information,
So as to search whether include touch screen facility information.
Wherein, as a kind of specific embodiment, the interface connecting with touch panel is USB interface, and external equipment sets for HID
It is standby.
Specifically, touch panel generally uses USB interface, and USB interface meets HID specification, so touch screen is as a kind of
HID device is used for human-computer interaction.In the present embodiment, setting for all HID external equipments specifically can be obtained using HID control bus
Standby information, therefrom to search whether the facility information of touch screen.
The restoration methods of touch screen failure provided herein, on the basis of the above, as a kind of preferred reality
Example is applied, after the interface that control is connect with touch panel resets, further includes:
Update the interface that is connect with touch panel of detection whether communication failure；
If so, continuing to execute the step of interface that control is connect with touch panel resets；
If it is not, the communication connection for then updating current application program and touch panel configures, to restore current application program
To the calling of touch panel.
Specifically, in the present embodiment, after restarting touch panel, the interface connecting with touch panel can also be judged again
Whether communication failure, so as to further confirm that touch failure the problem of whether be resolved.If not yet solved, can answer again
Restart touch panel in position；If be resolved, it can also further restore current application program at this time to touch panel
Calling.
Described current application program is currently running in host equipment as when touch screen occurs to touch Its Failures
Application program.After touch panel is restarted, current application program and the communication connection of touch panel script are no longer valid, need
It re-establishes, so that current application program can continue to call touch panel, and the touch data from touch panel is done
It reacts out.
Wherein, the communication connection of described update current application program and touch panel, which configures, includes:
Close the communication connection that failure is closed to the calling function of touch panel；
Unlatching re-establishes effective communication connection to the calling function of touch panel.
Above content can control reference Fig. 2, Fig. 2 is the restoration methods of touch screen failure provided herein in another tool
Flow chart in body embodiment.
S21: the data file of each external equipment in polling system bus obtains external equipment information.
S22: judge the external equipment information got whether include touch screen facility information；If it is not, then entering S23.
S23: the interface that control is connect with touch panel resets, to restart touch panel.
S24: the data file of each external equipment in polling system bus obtains updated external equipment information.
S25: judge updated external equipment information whether include touch screen facility information；If so, into S26；
If it is not, then entering S23.
S26: the communication connection that failure is closed to the calling function of touch panel is closed；Into S27.
S27: unlatching re-establishes effective communication connection to the calling function of touch panel.
