Abstract
The utility model provides a Bluetooth projector which integrates a projector and Bluetooth technology. A processor of the utility model which is connected with the Bluetooth module through address data bus and connected with the projector through a serial port is used for transferring data read-written by the projector to the Bluetooth module which communicates with a Bluetooth mobile phone in a Bluetooth wireless mode and then connecting with the mobile phone to perform projecting output. When the Bluetooth projector needs to be in connection with the Bluetooth mobile phone, the Bluetooth mobile phone first searches for SPP service information of the Bluetooth projector through SDP service and then is connected with the SPP service of the Bluetooth projector through the connecting base band, L2CAP and RFCOMM protocols.
Description
Technical field
The present invention relates to the communications field, relate in particular to Bluetooth wireless technology and porjector technology.
Background technology
Bluetooth (Bluetooth) is a kind of emerging short distance radio communication standards, is a kind of small-sized, economic, the short-range Radio Link of setting up between portable computer, mobile phone and other mobile device.The frequency range of this regulation and stipulation work is public ISM band, and peak data rate can reach 3Mbps.Utilize the equipment of Bluetooth technology communication to spread all trades and professions at present, as mobile phone, notebook, PDA, digital camera etc.These equipment are by Bluetooth technology wirelessly transmitting data easily.
The bluetooth projector combines projector with Bluetooth technology, make projector except modes such as traditional connection computer, TV, also supports the wireless connections mode with bluetooth equipment.Only need just the data on bluetooth cellular phone, bluetooth PDA, bluetooth notebook computer or other bluetooth equipments to be projected, greatly made things convenient for the use of portable projector by shirtsleeve operation.Existing projector all is not to be with the blue teeth wireless function, how to realize that this function promptly is that the present invention is with the problem that solves.
Summary of the invention
The present invention will provide a kind of bluetooth projector that projector and Bluetooth technology are integrated.The object of the present invention is achieved like this:
As Fig. 1, the bluetooth projector is characterized in that hardware comprises processor (3).Processor (3) is the control core of bluetooth projector, and processor (3) links to each other with bluetooth module (1) by serial ports, and bluetooth module (1) links to each other with antenna (6) by radio frequency interface, and antenna (6) is used for the transmitting/receiving wireless signal.RAM (7) links to each other with processor (3) by address data bus, and Flash (4) links to each other with processor (3) by address data bus, is used for storing data information.The other end of processor (3) links to each other with projector (2) by serial ports.Bluetooth module (1) passes through the communication of blue teeth wireless mode with bluetooth cellular phone (5), is used to connect mobile phone and carries out projection output.
The bluetooth projector also has another kind of square stock or the formula of realizing, and is basic identical with Fig. 1 as shown in Figure 2, unique difference be bluetooth module (1) inner integrated processor (3), Flash (4), RAM (7) and antenna (6).
Bluetooth projector protocol model figure as shown in Figure 3, when bluetooth projector (9) needs to connect bluetooth cellular phone (8), bluetooth cellular phone (8) is connected to the SPP service of bluetooth projector (9) then by the SPP information on services of SDP service-seeking bluetooth projector (9) by connection base band, L2CAP, RFCOMM agreement.
