Description
Technical field
The utility model relates to wireless communication field, relates in particular to a kind of radio communication device.
Background technology
Along with BlueTooth(bluetooth), the wireless communication technology such as ZigBee, Wi-Fi ripe and rising, great majority have the portable electronic products (mainly referring to have the products such as mobile phone, net book, panel computer of numeral, letter and spcial character input key) of character input function by configuration corresponding radio function module (as: Wi-Fi), realized and in portable electronic products, inputted user name (SSID) and encrypted message carries out the radio communication function after authentication, to user, brought service experience easily.
Some electronic products (as: monitoring camera, motion cameras, portable scanner, drive recorder etc.) on electronic market are owing to itself there is no button or the functional module of inputting character information at present, cannot be by product input SSID itself and password when carrying out radio communication, or the unpaired message that cannot send relevant apparatus carries out authentication, so these electronic products can not be realized radio communication function by product itself.
Monitoring camera for example, owing to itself there is no the button of inputting character information, also not with touch-screen that can inputting character information, therefore cannot to the pairing request information of relevant apparatus transmission, carry out authentication by monitoring camera itself, cause carrying out radio communication with relevant apparatus.Especially in the large-scale public arena that needs conduct monitoring at all levels, need the huge wired network system of layout to connect each monitoring camera, like this needs are spent to a large amount of human and material resources, financial resources are carried out layout circuit, and need often circuit to be safeguarded, all bring great inconvenience to user and attendant.
Equally, the electronic products such as the motion cameras on market, portable scanner, drive recorder are because the size of its product own is less, be not easy to arrange more character input key or touch-screen that can inputting character information, so can only the mode to PC end communicate by port connection data line.When user's needs in real time and other device communicates under some constrained environment, there is inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of radio communication device, the electronic product that makes not possess character input function exempt from input validation information just can with other device wireless communication.
For achieving the above object, the utility model is by the following technical solutions:
A kind of radio communication device, comprise sender unit, signal receiving device and wireless module, sender unit comprises main control module, signal generator module, coding module and the signal transmitting terminal connecting successively, signal receiving device comprises signal receiving end, signal decoding module and the main control unit connecting successively, main control unit connects wireless module, and signal transmitting terminal connects described signal receiving end by audio signal.
Further, signal transmitting terminal is loud speaker.
Further, audio signal is dtmf signal.
Further, signal receiving end comprises microphone and sound treatment circuit, and microphone is connected with sound treatment circuit, and sound treatment circuit is connected with signal decoding module.
Further, wireless module is Wi-Fi module, bluetooth module or ZigBee module.
The utility model beneficial effect is compared with prior art:
The utility model generates audio signal by sender unit by the user name (SSID) of input and encrypted message, and it is encoded, then by signal transmitting terminal, be sent to the signal receiving end of signal receiving device, by signal decoding module, its decoding is carried out to authentication afterwards, after authentication success, open wireless module and carry out radio communication, realized the function that self does not possess signal receiving device and other device wireless communication of character input function, saved resource, expand range of application, improved data transmission efficiency.

Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is described further and is illustrated.
The system block diagram of the utility model embodiment as shown in Figure 1.The radio communication device of the present embodiment comprises sender unit 10, signal receiving device 20 and wireless module 30.Sender unit 10 be mobile phone, panel computer and so on can inputting character information electronic equipment.Signal receiving device 20 and wireless module 30 are that monitoring camera, motion cameras, portable scanner, drive recorder etc. itself do not possess the part device of the electronic equipment internal of input module or device.Sender unit 10 comprises main control module 11, signal generator module 12, coding module 13 and the signal transmitting terminal 14 connecting successively.Signal receiving device 20 comprises signal receiving end 22, signal decoding module 23 and the main control unit 21 connecting successively.Main control unit 21 connects wireless module 30.Signal transmitting terminal 14 connects described signal receiving end 22 by audio signal, and this audio signal is dtmf signal.
As shown in Figure 2, the course of work of the present embodiment is achieved in that
On the screen of sender unit 10, eject the dialog box of an input SSID and password, the button of user by sender unit 10 or touch-screen input SSID(as: 5D2F), signal generator module 12 is encoded into corresponding hexadecimal dtmf signal by SSID, and after SSID input, application program module finishes the input of SSID with hexadecimal 0X00.In like manner, by button or the touch-screen input password (as: 123456) of sender unit 10, signal generator module 12 becomes corresponding hexadecimal dtmf signal by cipher coding, after Password Input, with hexadecimal 0X00, finishes Password Input.Main control module 11 is loud speaker by signal transmitting terminal 14() the hexadecimal dtmf signal of above-mentioned SSID and password is externally launched.
The technical scheme of the disclosed DTMF of the utilization Principle of Communication of the utility model wireless transmission SSID and password is not only applicable to SSID and the password to signal receiving device 20 wireless transmission WIFI by sender unit 10, equally also be applicable to by sender unit 10 to the unpaired message of the wireless input bluetooth of signal receiving device 20 and ZigBee confirmation etc., thus the radio communication function between implement device.
The principle that 13 pairs of dtmf signals of sender unit 10 execution coding modules of the present embodiment are encoded is such:
The present embodiment utilizes two dtmf signals to represent a character (this mode is called to hexadecimal method).Owing to there being 16 kinds of different dtmf signals (0-9, A, B, C, D, E(*), F(#)), ASCII character is metric 0-255 again, turning to hexadecimal is 0X00-0XFF, just can represent the hexadecimal character of two with two dtmf signals.Therefore, its corresponding relation may be defined as table 1.
Table 1ASCII code and two hexadecimal tables that dtmf signal is corresponding
Remarks: X1, X2 represents respectively first signal and the second signal in two dtmf signals.
More than statement only further illustrates technology contents of the present utility model with embodiment; so that reader is easier to understand; but do not represent that execution mode of the present utility model only limits to this, any technology of doing according to the utility model is extended or recreation, is all subject to protection of the present utility model.
