When switch is in 0 grade of state, touch screen is connected on the first PC, and calibration data will be saved in this state On touch-control control panel, and also save in the MCU module of touch screen USB multi-channel switcher the calibration data of the first PC;
When switch is in 1 grade of state, touch screen is connected on the 2nd PC, in this state to calibration data relative to The calibration data that first PC state saves is mapped, and is obtained and is saved mapping relations.
In a preferred embodiment of the present invention, it is defeated to be provided with HDMI output end, USB by the first PC and the 2nd PC Outlet and USB input.
In a preferred embodiment of the present invention, the HDMI output end of the first PC and the 2nd PC with HDMI multichannel Switch is connected;The USB output end of first PC and the 2nd PC are connected with generic USB multi-channel switcher;It is described The first PC and the USB input of the 2nd PC be connected with touch screen USB multi-channel switcher.
In a preferred embodiment of the present invention, there are two gears, including 0 grade and 1 grade for switch setting.
The beneficial effects of the present invention are: more host list touching display screen switching systems of the invention, can support dual system Between switch quick and smoothly, and touch-control does not have deviation after switching completion, greatly reduces workload, corrected rate is high.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other Attached drawing, in which:
Fig. 1 is the structural block diagram of a preferred embodiment of the more host list touching display screen switching systems of the present invention;
Fig. 2 is the correcting process figure of touch screen USB multi-channel switcher in Fig. 1;
Fig. 3 is the normal work flow chart of touch screen USB multi-channel switcher in Fig. 1.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.
As shown in Figure 1, the embodiment of the present invention includes:
A kind of more host list touching display screen switching systems, including it is the first PC, the 2nd PC, HDMI multi-channel switcher, common USB multi-channel switcher, touch screen USB multi-channel switcher, touch screen, USB interface, touch-control control panel and switch, described One PC and the 2nd PC is connected with HDMI multi-channel switcher, generic USB multi-channel switcher, touch screen USB multi-channel switcher, institute The HDMI multi-channel switcher stated, generic USB multi-channel switcher, touch screen USB multi-channel switcher respectively with touch screen, USB interface Be connected with touch-control control panel, the switch respectively with HDMI multi-channel switcher, generic USB multi-channel switcher, touch screen USB Multi-channel switcher is connected.
Among the above, the first PC and the 2nd PC are provided with HDMI output end, USB output end and USB input.
Wherein, the HDMI output end of the first PC and the 2nd PC is connected with HDMI multi-channel switcher;Described The USB output end of first PC and the 2nd PC is connected with generic USB multi-channel switcher;First PC's and the 2nd PC USB input is connected with touch screen USB multi-channel switcher.
Further, there are two gears, including 0 grade and 1 grade for switch setting.
In the present embodiment, HDMI multi-channel switcher does the switching of HDMI;Generic USB multi-channel switcher generic USB is cut It changes;Touch screen USB multi-channel switcher will complete switching of the touch-control control panel between the first PC and the 2nd PC, due to there was only one A touch-control control panel, and coordinate system informations can be saved in the equipment.But the coordinate system of usual first PC and the 2nd PC is that have Some deviations, therefore touch screen USB multi-channel switcher can be corrected by certain algorithm.
More host list touching display screen switching systems of the invention are modified touch-control by touch screen USB multi-channel switcher Deviation.As shown in Fig. 2, the calibration process of the touch screen USB multi-channel switcher amendment touch-control deviation includes walking in detail below It is rapid:
When switch is in 0 grade of state, touch screen is connected on the first PC, and calibration data will be saved in this state On touch-control control panel, and also save in the MCU module of touch screen USB multi-channel switcher the calibration data of the first PC;
When switch is in 1 grade of state, touch screen is connected on the 2nd PC, in this state to calibration data relative to The calibration data that first PC state saves is mapped, and is obtained and is saved mapping relations.
As shown in figure 3, the normal workflow of touch screen USB multi-channel switcher, when switch is in 0 state, touch-control Screen equipment is attached on PC1, and the USB Report of touch screen is directly sent to PC1 under the state;When switch is in 1 When state, touchpad device is attached on PC2, and the HID Report of touch screen USB generation is obtained under the state simultaneously Coordinate points are parsed, coordinate points are mapped to PC2 coordinate system according to the mapping relations that PC1 coordinate is mapped to PC2 coordinate, by new seat Pointing information group packet is sent to PC2.
In conclusion more host list touching display screen switching systems of the invention, can support quickly to flow between dual system Freely switch, and switch the later touch-control of completion there is no deviation, greatly reduces workload, corrected rate is high.
