Abstract
Disclosed is a multifunctional multimedia company based on the Bluetooth technology, consisting of a mobile terminal and a fixed terminal. The hardware part of the mobile terminal is composed of a battery, a functional keyboard, a laser transmitter, a microcontroller, a Bluetooth serial module and a telescopic pointer. The hardware part of the fixed terminal is composed of a computer host and a Bluetooth USB module. The multimedia company provides the functions of file page turning, full screen, exit from full screen and file switching of the computer operation by remote control; a laser pen and a pointer are embedded in the mobile terminal, thus the lecturer can easily operate files towards any direction at any position of the demonstration occasion such as a classroom or a meeting room and point the laser pen or the pointer to the position where the audients need pay attention to, and the lecturer can freely communicate with the audients. The multifunctional multimedia company provides great convenience for the occasions for business demonstration, teaching and giving a meeting.
Description
Technical field
The present invention utilizes Bluetooth technology to have low-power consumption, communication security, direction-free characteristics at short-distance wireless communication, on portable terminal and fixed terminal, embed bluetooth module, between portable terminal and fixed terminal, set up the Radio Link of safety, reach the purpose of straighforward operation.
Background technology
When in business presentations, meeting, teaching, adopting the demonstration of multimedia large-screen document at present, some demonstrator likes using teacher's pointer or laser pen to point to large-screen explaining while demonstrating, when presentation file needs page turning, the demonstrator has to walk back the computer limit, use mouse or keyboard to operate, this freely brings into play etc. for the demonstrator and has brought numerous inconvenience.
Remote control in the market uses the many of infrared technique making, but infrared technique has tangible directivity, coverage is also very little under the prerequisite of low-power consumption.Bluetooth technology has low-power consumption, communication security, characteristics such as non-directional, and along with the development of electronic industry, the bluetooth module cost has fallen very lowly, has obtained using widely at portable terminal computer.
Summary of the invention
To the objective of the invention is the problem that exists in the above-mentioned background technology in order solving, a kind of multi-functional multimedia companion based on Bluetooth technology to be provided.Use the present invention, the demonstrator can be in any position in meeting room or classroom indiscriminately ad. as one wishes straighforward operation computer and explanation document.
The object of the present invention is achieved like this:
A kind of multi-functional multimedia companion based on Bluetooth technology is made up of portable terminal and fixed terminal two parts.The portable terminal hardware components is made up of battery, function keyboard, generating laser, microcontroller, bluetooth serial ports module, pullable teacher's pointer.The fixed terminal hardware components is made up of host computer and bluetooth USB module.
When whole system works on power, when using portable terminal straighforward operation computer, as long as the user is by the function corresponding key, just can to fixed terminal send document page turning, document switch, full frame, withdraw from full frame instruction, the microcontroller of portable terminal can detect key information automatically, is that Bluetooth protocol bag send the USB bluetooth module that be given to fixed terminal by the bluetooth serial ports module with instruction transformation with the agreement that provides in advance, main frame is passed in the instruction that USB bluetooth module on the fixed terminal will receive, and then realizes remote operation main frame purpose.Because bluetooth has direction-free advantage, so the user just can be in bluetooth module coverage (can reach 100 meters) arbitrary manipulation computer.
When the red laser indication large-screen of use portable terminal or demonstration board explanation,, just red laser can be got to any position of large-screen as long as the user pins laser switch.
When using the teacher's pointer indication large-screen demonstration of portable terminal,, just can normally use as long as the teacher's pointer that the user will be embedded in the product is released.
Effect of the present invention:
As mentioned above, the invention provides the document page turning of straighforward operation computer, full frame, withdraw from full frame, document handoff functionality, and laser pen and teacher's pointer on portable terminal, have been embedded, make that the demonstrator can be comfortable in the classroom, any one surface of position in demonstration place such as meeting room is to any one direction operation document, and point to laser pen or teacher's pointer and to wish that spectators should be noted that the place, the demonstrator can be followed one's bent exchange, for occasions such as business presentations, teaching, meeting provide a great convenience with spectators.
In addition, the present invention is a new application of Bluetooth technology, will make high contribution for the development in bluetooth market.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
Description of drawings
Fig. 1 is system's Bluetooth remote control part block diagram,
Fig. 2 is whole portable terminal schematic diagram.
The label declaration of major part in the accompanying drawing:
1. 2. laser pen part of Bluetooth remote control part
But 3. 4. microcontroller of pull teacher's pointer
5. 6. battery of function keyboard
Specific implementation method
With reference to the accompanying drawings, implementation method of the present invention is elaborated.
Fig. 1 is the structured flowchart of system's Bluetooth remote control part.
As shown in Figure 1, microcontroller is handled user key-press information among the present invention, then command adapted thereto is sent instruction by the bluetooth serial ports module with the agreement that provides in advance.The bluetooth USB module of fixed terminal is sent to main frame with the command information that receives, and main frame just can carry out respective handling.
Fig. 2 is the schematic diagram of whole portable terminal.
As shown in Figure 2, portable terminal comprises function keyboard, microcontroller, Bluetooth remote control part, pullable teacher's pointer, battery six parts composition among the present invention.Battery is to microcontroller circuit, module and laser pen power supply.Function keyboard is the man-machine interface that provides to the user, and by the function corresponding key, processor detects key information and sends the main frame of command adapted thereto to fixed terminal the user automatically according to own wish, and then realizes corresponding operating.
Laser pen can be opened and use to the laser key switch as long as the user press...withes one's finger just, decontrols switch as long as the back of finishing using will be pointed, and just can close laser pen.
The user just can use teacher's pointer as long as extract pullable teacher's pointer out, after finishing using teacher's pointer is retracted portable terminal and gets final product.
