Embodiment bis-
In order to be illustrated more clearly in laser-assisted document transmission method provided by the invention, introduce the method as an example of bluetooth equipment example below.
The bluetooth equipment that the embodiment of the present invention provides, comprises generating laser and laser pickoff, assists pairing and the checking of bluetooth equipment by generating laser and laser pickoff, and transmits file request and send order.
In the time that need send the order that bluetooth is set up and file sends, bluetooth equipment uses certain form to be modulated in the laser beam of generating laser transmitting the order that bluetooth is set up and file sends, and utilizes laser beam to transmit the order that bluetooth is set up and file sends.
Wherein, the form of the command information of Laser emission has good autgmentability, and content is not only confined to certain specific function, can also be the combination of series of orders.Such as similar order can be: " bluetooth equipment to certain physical address is set up request, and checking PIN code is 123456, and waits for a card information of acceptance ";
" opened bluetooth function, sets up request to the bluetooth equipment of certain physical address, and checking PIN code is 123456, and downloads the specified file under a path by bluetooth passage FTP, immediate cancel pairing after completing ".
Wherein, generating laser uses visible light beam.And, the state of the constant luminance that is not suitable intensity containing the laser beam of modulation orders, being convenient to reflector one end can accurately be registered to receiving terminal by light beam under artificial control.For the ease of aiming at the bluetooth equipment of receiving terminal, can adjust the focusing of the laser beam of the bluetooth equipment of transmitting terminal, make light beam can cover a suitable scope in the distance at receiving terminal place, can not cover other Bluetooth terminals that close on simultaneously.For example, utilize lens to make laser beam produce the scattering of certain angle at Laser emission end, thereby can cover a suitable scope in the distance at receiving terminal place.
After laser beam has been aimed at, send at laser transmitting terminal trigger command, order to be sent is just can be immediately modulated and follow laser beam to send to receiving terminal.Debug data mode on laser beam can frequency of utilization be modulated, or uses the variety of way such as switch, power of light source.In practical application, the manufacturing cost based on equipment is chosen the best alternatives between various modulation systems.
When laser pick-off end determines the modulation signal that laser beam contains characteristic frequency, start to accept laser and demodulate wherein order.Order is carried out the inspections such as grammer, safety after having accepted, and checks by starting to carry out the order that this receives.
Consider the stricter security control of receiving terminal, laser pickoff can cut out.Open or close in situation at laser pickoff, there is certain instruction equipment outer end, makes external energy directly see and distinguish the operating state of laser pickoff.
Transmitting power and the beam focus of laser beam can be set, in order to tackle the variation of mobile phone spacing.At some special occasions, (un-encoded) laser beam continuing that generating laser sends can be used as cursor prompting or lighting device.
Taking the mobile phone with Bluetooth function, the document transmission method based on bluetooth provided by the invention is described as bluetooth equipment as example below, as shown in Figure 2, comprises the following steps:
Step 201, A mobile phone is aimed at B mobile phone, sends the unpaired message of the bluetooth equipment of A to B mobile phone by laser beam.
Wherein, unpaired message can comprise implementor name, device address, the verification identifying code of bluetooth equipment, and filename to be sent (as pairing information, optional).B mobile phone receives and parses the order by Laser Modulation.
Step 202, B mobile phone open Bluetooth function, initiates Bluetooth pairing request to A mobile phone.
Use the check code obtaining by laser beam, the mutual verification between the finishing equipment of system backstage.And be that opposite end arranges access rights at software layer.
Step 203, Bluetooth pairing success, A monitoring mobile phone to B mobile phone between bluetooth be connected and can use, A mobile phone passes through bluetooth Transmit message to B mobile phone.
By adopting method provided by the invention, simplify the step of manual operation, accelerate to transmit by bluetooth between mobile phone the speed of file.Because laser beam has the directed characteristic of transmitting, can only receive information by the equipment in human eye visible range, therefore control appliance fail safe intuitively.In addition, the operating right of laser pickoff can be set, when the information that reaches is transmitted convenience, reach the controlled of fail safe.The mobile phone command of Laser Modulation is not only applicable to auxiliary bluetooth and sets up, and can expand to be common between neighbouring device, sending a small amount of data message and on distant terminal, carrying out one group of affairs for triggering simultaneously.The generating laser of holding state and recipient can be in the states of extremely low power dissipation, very little to the battery consumption of cell phone apparatus.
Need explanation, the laser-assisted document transmission method that the embodiment of the present invention provides, is not only applicable to bluetooth equipment, and other equipment can be suitable for equally.For example, when cellphone subscriber enters wireless network region, laser assistance can send to the username and password of wireless network on mobile phone by laser beam, and mobile phone both can have been logined this wireless network according to this username and password.
Based on the technical conceive identical with said method embodiment, the embodiment of the present invention also provides following apparatus item embodiment.
