Specifically, the touch screen and the display device can be connected to the winning kylin system in various communication modes, and the embodiment of the invention is preferably exemplified by a USB touch screen and a DVI display device; when a plurality of display devices with touch screens are connected to a winning kylin operating system host, judging whether all the accessed touch screens are identified by the operating system by detecting USB information, for example, judging whether all the touch devices are accessed by the number of device numbers driven by USB; then acquiring firmware information of all touch screens to distinguish; judging whether all display devices are all identified by the winning kylin operating system by the EDID information of the display device driven by the display card, providing a data structure for each accessed display device by an internal server of the winning kylin operating system, the EDID information of the display equipment is mapped into a corresponding data structure, and then mapping resources are converted into matrix information of the corresponding display equipment for distinguishing; and the problem of distinguishing the equipment is solved, and the touch screen and the display equipment are bound. After the touch screen is clicked, the USB driver transmits the coordinate values of the touch screen to the kernel of the winning kylin system, the kernel of the winning bid kylin system is displayed according to the binding result the result of (2) is handed to the bound display to complete click display. For example, the touch screen 1, the display device 1, the touch screen 2, the display device 2 and the … … touch screen N and the display device N are all in communication connection with the winning-order kylin system through USB interfaces, and the winning-order kylin system obtains registration information and numbers of the touch screen 1 to the touch screen N devices under the winning-order kylin operating system in a USB driving registration mode, and distinguishes the registration information and the numbers; meanwhile, the display card driver detects EDID information of the display devices 1 to N; mapping resources of information such as resolution, coordinates and the like of all display equipment in a server are obtained, and the resources are converted into corresponding matrix information; and binding the touch screen 1 with the display device 1 and binding the touch screen with the display device 2 … … until the touch screen N and the display device N according to the touch screen registration information and the matrix information of the number and the display device, and completing the matching and calibration of all the touch screens and the display device.
The embodiment of the invention provides a matching method of a multi-touch screen and display equipment, which realizes the matching calibration of each touch screen and each display equipment under a winning kylin operating system by simultaneously acquiring firmware information of a plurality of touch screen equipment and EDID information of the display equipment, distinguishing the firmware information and the EDID information of the display equipment, and binding registration information and numbers of the touch screens with matrix information of the display equipment.
Further, fig. 2 is a schematic view of a touch screen distinguishing flow chart according to an embodiment of the present invention; as shown in fig. 2, the step S2 specifically includes:
s21, acquiring firmware information of a plurality of touch screens, and judging the state of the firmware information;
s22, the division of the touch screen is completed directly through the firmware information or the division of the touch screen is completed through the hardware interface number of the touch screen connection mainboard.
Specifically, firmware information of a plurality of touch screens obtained through USB is used for judging whether all touch screens can be distinguished directly through the firmware information; if the firmware information of all touch screens is completely consistent, only the hardware connection of the touch screens to the main board can be used for distinguishing, and the universality is better through the distinction of the connection interface numbers; if the firmware information is different, the firmware information is distinguished simply directly; for example, the winning kylin operating system directly reads the device ID or vendor name of different touch screens to complete the distinction, or directly obtains the PCI bus port number of the touch screen connection to complete the distinction. Because the mode of first powering on and first identifying is adopted, when the powering-on time of different touch screen devices is different, the acquired firmware information of the touch screens is distinguished, and the problem of touch screen resource drift is avoided to a certain extent.

s31, EDID information of a plurality of display devices is obtained, and the state of the EDID information is judged;
s32, the display equipment is distinguished directly through the EDID information or distinguished through a hardware interface number of a mainboard connected with the display equipment.
Specifically, whether all display devices can directly finish distinguishing is determined according to the EDID information of a plurality of display devices, such as display device resolution, coordinates, provider information, maximum image size, color setting, display names, serial numbers and the like; if the EDID information of all the display devices is completely consistent, only the hardware connection number of the display devices connected to the main board can be adopted; such as a connected PCI bus port or the like.
Further, fig. 4 is a flowchart of automatic matching between a multi-touch screen and a display device according to an embodiment of the present invention; as shown in fig. 4, the plurality of touch screens and the display device can automatically complete matching when the touch screen is started or restarted.
Firstly, modifying a linux udev rule, setting a display or a touch screen to be re-connected to a system, and then sending a signal to a matching program;
secondly, when the matching program acquires the corresponding information of the display and the touch screen, the execution program is automatically revised;
finally, matching operation is executed to realize automatic matching of the multiple touch screens;
specifically, the winning kylin operating system is started or restarted, and when the display device and the touch screen are re-connected to the system, the matching function of the multi-touch screen and the display device cannot be directly operated; here, the udev mechanism under the operating system of the winning kylin is directly adopted, and udev is a Linux kernel 2.6 series device manager. After the USB equipment is accessed into an operating system, a kernel sends a signal and executes a corresponding udev program, namely a multi-screen touch matching program; the automatic matching of the matching program is successfully realized.
The embodiment of the invention provides a matching method of a multi-touch screen and display equipment, which comprises the steps of simultaneously acquiring firmware information of a plurality of touch screen equipment and EDID information of the display equipment, distinguishing the firmware information and the EDID information of the plurality of touch screen equipment, and binding registration information and numbers of the touch screens with matrix information of the display equipment, so that matching calibration of each touch screen and each display equipment under a winning kylin operating system is realized; the problem of touch screen resource drift is avoided to a certain extent.
