Abstract
The utility model discloses a wireless handwriting board based on a mobile phone, which comprises a touch screen module, a baseband unit, a Bluetooth module, an antenna and a driving module, wherein an output of the touch screen module is connected with an input end of the baseband unit; the baseband unit is connected with the Bluetooth module by the driving module; and the Bluetooth module has communication with a personal computer (PC) by the antenna. By combining the mobile phone and the handwriting board, the wireless handwriting board based on the mobile phone not only saves the resource and leads the mobile phone to be conveniently carried, but also leads the function to be more practical and is conveniently applied to occasions of computer text input, drawing, demonstration and the like.
Description
Technical field
The utility model relates to a kind of mobile phone, in particular a kind of wireless handwriting pad based on mobile phone.
Background technology
Nowadays touch-screen mobile phone is very popular, different with traditional numeric keyboard of mobile telephone input mode, the literal input of touch-screen mobile phone can be write on mobile phone screen by using felt pen or finger, by the recognition system of mobile phone inside hand-written various fonts are converted to the discernible standard letter of mobile phone again and are presented on the mobile phone screen, so just improved the speed of input greatly.
The main input mode of PC (personal computer personal computer) is to use keyboard and mouse at present, wish to carry out literal or picture input as the user by handwriting mode, then need to purchase in addition handwriting pad equipment, and handwriting pad on the market all is wired basically, is inconvenient to use.Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide a kind of wireless handwriting pad based on mobile phone, is intended to solve existing wired handwriting pad and uses inconvenient problem, and mobile phone and handwriting pad united two into one reach aim of saving.
The technical solution of the utility model is as follows:
A kind of wireless handwriting pad based on mobile phone, it comprises touch screen module, Base Band Unit, bluetooth module and antenna, wherein, also comprise a driver module, the output of described touch screen module connects the input end of Base Band Unit, Base Band Unit connects bluetooth module by driver module, and bluetooth module is communicated by letter with PC by antenna.
Described wireless handwriting pad based on mobile phone, wherein, comprise ADC and arithmetic element in Base Band Unit, described ADC receives the output of described touch screen module, and transformation result is delivered to the input end of described arithmetic element, described arithmetic element is imported driver module with final data.
Described wireless handwriting pad based on mobile phone, wherein, described ADC adopts the high chip of conversion accuracy.
A kind of wireless handwriting pad provided by the utility model based on mobile phone, owing to utilized the bluetooth module on mobile phone and the PC, the mobile phone and the PC of band touch-screen set up data communication easily, in mobile phone end the respective drive module is installed, hand-written information on the mobile phone screen is sent to the PC end by bluetooth, PC is converted to discernible literal or image information after the data of receiving are handled, and has promptly realized wireless handwriting pad function.Mobile phone and handwriting pad are merged, not only saved the portable of resource but also mobile phone, also make this function practical more, can be conveniently used in occasions such as computer writing input, drawing and demonstration.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, below the utility model is further described with reference to the accompanying drawing embodiment that develops simultaneously.
The utility model is based on the touch-screen mobile phone with Bluetooth function, and Bluetooth adapter will be installed on the PC or directly be plugged with general USB (Universal Serial BUS USB (universal serial bus)) Bluetooth adapter.
Referring to Fig. 1, as the user picture taking place on touch screen module 11 writes when action, picture will take place touch screen module 11 writes the position of action and is converted into analog voltage signal, and this analog voltage signal is passed to Base Band Unit 12.ADC in the Base Band Unit 12 (Analog-to-Digital Converter analog-to-digital conversion module) 122 is converted into digital signal with analog voltage signal, gives arithmetic element 121 through the digital signal transfers that ADC122 transforms.Arithmetic element 121 obtains the movement locus coordinate data through simple computing again, and this coordinate data passes to bluetooth module 13 by the driver in the driver module 10.Bluetooth module 13 is launched coordinate data by antenna 14 by Bluetooth signal 15.
The computing method of ADC algorithm and arithmetic element, disclosed in existing technology, no longer the technology of this part is done at this and to be given unnecessary details.
The coordinate data that driver module 10 will come the arithmetic element transmission rapidly is loaded on the bluetooth module 13, bluetooth module 13 can be sent to coordinate data on the Bluetooth Receiver of PC end fast, thereby realize function fast, therefore driver module 10 requires processing speed fast, makes hand-written effect not have delay.
Mobile phone is at first wanted opened bluetooth function, and the PC end is also opened Bluetooth function simultaneously; A certain then square tube is crossed to search and is determined connecting object, when determining to send the request of connecting behind the good connecting object, just can realize communication between the two after connecting.
After the PC termination of band Bluetooth function is received Bluetooth signal, therefrom obtain just can judging the physical location of contact after the coordinate data, thereby simulate the track that picture is write.The processor (as computing machine) that receives this actual location data just can restore image or literal and judge correct literal or image according to the property data base that has been stored in the processor according to track, realizes handwriting functions.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
Claims (3)
1. wireless handwriting pad based on mobile phone, it comprises touch screen module, Base Band Unit, bluetooth module and antenna, it is characterized in that, also comprise a driver module, the output of described touch screen module connects the input end of Base Band Unit, Base Band Unit connects bluetooth module by driver module, and bluetooth module is communicated by letter with PC by antenna.
2. the wireless handwriting pad based on mobile phone according to claim 1, it is characterized in that, in Base Band Unit, comprise ADC and arithmetic element, described ADC receives the output of described touch screen module, and transformation result is delivered to the input end of described arithmetic element, described arithmetic element is imported driver module with final data.
3. the wireless handwriting pad based on mobile phone according to claim 2 is characterized in that, described ADC adopts the high chip of conversion accuracy.
