Background technique
With the rapid development of mobile Internet, a kind of Android (open source code operation system based on Linux
System) etc. some Mobile operating systems be also widely used in a large amount of multimedia equipments such as TV, for example, Android intelligent television,
Android set-top box and Android high definition player etc..Therefore, to the various control modes of these multimedia equipments
Also it emerges in multitude therewith.
Touching manipulation be at present in mobile phone and tablet computer using wider control mode, if but this mode it is direct
Applied to the manipulation of the multimedia equipments such as the television set, set-top box, player that need to be shown on large screen, then need entire large-size screen monitors
Curtain is used as touch screen, and not only cost is huge, but also needs user to walk close to large screen and manipulate, inconvenient for use.
Therefore, it is necessary to the manipulation to above-mentioned multimedia equipment is realized using wireless remote control technology.
Currently, what is generallyd use is Infrared Ray Remote Control Technology.Infrared Ray Remote Control Technology uses the infrared optical transmission signal of 850nm,
It can be realized point-to-point simple data transmission and file synchronization.Due to it have structure is simple, systems technology complexity is small, at
The advantages that this low, good directionality, information security are high and available frequency resources are more, therefore generally answered in the remote control technology of household electrical appliances
With.But Infrared Ray Remote Control Technology requires must have accessible beeline channel between equipment, and there are also logical for this remote control technology
Believe the disadvantages of range is small, and penetration capacity is poor, and the number of devices of support is few.
In addition to this, the rapid development of household electrical appliance information-based, smart home and family multi-media technology, to the letter of remote controler
Number transmission and mode of operation also proposed completely new requirement, then there is radio wave remote controler, wireless mouse and keyboard, sky
A variety of wireless remote control modes such as middle mouse and wireless touchpad.Radio wave remote controler only changes in transmission mode,
Mode of operation and IR remote controller do not have any difference, are operated by the focus of the mobile control of key up and down, cumbersome,
Inefficiency.Wireless mouse and keyboard are the keyboard and mouse wireless to computer, are operated more convenient, but volume
Greatly, mobile inconvenient, be not it is very portable, in addition can not be using being operated by the way of touch.Air mouse utilizes gravity sensor
Or gyroscope determines direction, the positioning of cursor is relatively difficult.Although wireless touchpad can be by the way of touch-control, not
Multi-point touch may be implemented, cannot achieve functions, the cursors such as picture scaling can not quickly position.
Summary of the invention
It is an object of the invention to solve the defect of the above-mentioned prior art, provide a kind of low cost, low-power consumption, it is portable,

Kind operating mode can be switched by a key.Under touch mode, touch screen 2021 supports multi-point touch, processor 204
Touch data is read, the serial ports format for supporting Android serial ports touch panel communication agreement is then encapsulated into, is sent to by serial ports
Wireless receiving and dispatching radio-frequency module.Under keystroke pattern, 2011 transverse screen display of display screen can design six press keys and be shown in display screen
On 2011, each key is a square box, and processor 204 is by the coordinate of reading touch point, and judgement should in processor 204
Which square box point belongs in, if belonging to some square box, the corresponding serial ports instruction of this square box is sent to serial ports, is led to
Cross the transmission of wireless receiving and dispatching radio-frequency module, the multimedia equipments 100 such as control Android high definition player.
In wireless touch screen control system of the invention, multimedia equipment 100 can select television set, set-top box, high definition
Player etc. is especially best with the multimedia equipment 100 equipped with Android operation system.It is set due to being connected to multimedia
The size of standby 100 large screen be it is uncertain, therefore, it is necessary to will be connected to the large screen of multimedia equipment 100 and wireless controlled
The size of touch screen 2021 in terminal device 200 processed does a ratio mapping, this mapping process can be set in multimedia
It is carried out in standby 100.It is 16: 9 capacitance plate as touch screen 2021 to use the aspect ration of 3.5 cun, effective touch area.
Since the size and aspect ration of touch screen 2021 are fixed, and the display resolution etc. of multimedia equipment 100 is not solid
Fixed, therefore, when wireless control terminal equipment 200 is matched with multimedia equipment 100, by the length and width of touch screen 2021
Maximum coordinates be sent to multimedia equipment 100.After multimedia equipment 100 obtains the resolution ratio of oneself, according to certain algorithm
A scale operation is done, by touch screen 2021 and the position put on the large-screen display equipment of multimedia equipment 100 is connected to and reflects
It penetrates.For example, a length of the 480 of touch screen 2021, a length of the 1920 of large-screen display equipment, then this proportionality coefficient can
It is taken as 1920/480, similar mapping can be carried out according to this to the mapping in width direction.Such mapping process, by wireless control
Each point on the touch screen 2021 of terminal device 200 is put with some on large screen or certain points are corresponding, to reach
The purpose for the multimedia equipment 100 for being connected to large screen is controlled by manipulating the touch screen 2021 of the small screen.
The dynamic generation dish in wireless touch screen control system provided the present invention also provides more than one each embodiments
Single method, specific as follows:
Control property is activated to obtain module 102 from the acquisition of system graphical user interface 101 system in multimedia equipment 100
After the attribute information for the component united on graphic user interface 101, the component on system graphical user interface 101 is reduced to simplify
Figure sends wireless controlled via wireless receiving and dispatching radio-frequency module 104 for the location coordinate information of the simplification figure and component Name
Terminal device 200 processed;
Wireless receiving and dispatching radio-frequency module 205 in wireless control terminal equipment 200 believes the position coordinates of the component received
Breath and component Name are sent to processor 204;Processor 204 is according to location coordinate information and multimedia equipment 100 and wirelessly
The screen map relationship of controlling terminal equipment 200 sends the simplification figure of the component on system graphical user interface 101 to aobvious
Show that module 201 is shown, and call and be stored in the local character library extended out in memory module 203, component Name is shown in simplification figure
In shape.
Above-mentioned simplified figure is chosen as rectangular, point, line segment or circle.The extraction of location coordinate information can there are many
Mode, for example, if simplified figure to be selected as to the coordinate value on two rectangular, this can be taken rectangular cornerwise vertex, it can also
With the coordinate value at the center for taking this rectangular and a vertex, it can indicate that the position coordinates of the component are believed with these coordinate value informations
Breath, to further reduce the transmission quantity of data, improves data transmission efficiency.
