Description
[technical field]
The utility model relates to identification and control field, particularly relates to a kind of ultrasonic identification and control system.
[background technology]
The control method of existing power consumption equipment roughly comprises the button of direct control equipment surface, knob or touch-screen, and is controlled by remote controller.
But in above-mentioned two kinds of control methods, need user directly at the enterprising line operate of power consumption equipment to the method for operation of the button of equipment surface, knob or touch-screen, operating process is quite loaded down with trivial details, and has certain danger.And by the method for remote controller operation, each power consumption equipment need be equipped with corresponding remote controller, also bring inconvenience to user.
Therefore, for above-mentioned technical problem, be necessary to provide a kind of novel ultrasonic identification and control system and recognition methods.
[utility model content]
The purpose of this utility model is to provide a kind of ultrasonic identification and control system, unhandy technical problem when which solving control power consumption equipment of the prior art.
In order to solve the problems of the technologies described above, the utility model provides a kind of ultrasonic identification and control system, comprises control terminal and controlled terminal, wherein:
Described control terminal comprises coding chip and is connected to the ultrasonic transmitter of described coding chip, and the control signal that described ultrasonic transmitter exports according to described coding chip generates the ultrasonic signal of characteristic frequency or specific wavelength and sends;
Described controlled terminal comprises microphone and is connected to the decoding chip of described microphone, described microphones mates described ultrasonic signal and described ultrasonic signal is converted to electrical signal transfer to described decoding chip, and described decoding chip controls described controlled terminal according to the described signal of telecommunication.
Preferably, described microphone comprises filter circuit, and described filter circuit sets the thresholding mated with described characteristic frequency or described specific wavelength.
Preferably, described microphone is MEMS microphone.
Preferably, described ultrasonic transmitter is loud speaker.
Preferably, described control terminal is mobile communication equipment.
Preferably, described controlled terminal is household electrical appliance.
The beneficial effects of the utility model are: the utility model provides a kind of novel identification and control system, the control that specific ultrasonic signal realizes corresponding controlled terminal is generated by control terminal, and then simplify operation, also save manpower, and save cost.
[accompanying drawing explanation]
Fig. 1 is the frame diagram of ultrasonic identification of the present utility model and control system;
Fig. 2 is the preferred embodiment of ultrasonic identification of the present utility model and control system.
[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.Following examples only for illustration of the utility model, but are not used in restriction scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of ultrasonic identification and control system 1, comprises control terminal 10 and controlled terminal 20.Control terminal 10 controls controlled terminal 20 by launching ultrasonic wave.Particularly, control terminal 10 comprises coding chip 11 and is connected to the ultrasonic transmitter 12 of coding chip 11, after control command is inputed to control terminal 10 by user, coding chip 11 carries out coding according to this control command and generates control signal, and this control signal is converted to the ultrasonic signal of characteristic frequency and outwards sends by ultrasonic transmitter 12.Wherein, this characteristic frequency and control command for controlled terminal 20 corresponding.In other words, the ultrasonic signal that ultrasonic transmitter 12 sends all has specific frequency, the visual ID making corresponding ultrasonic signal of this specific frequency.Based on the operation relation between frequency, velocity of wave and wavelength three, the ID of above-mentioned ultrasonic signal also can represent with specific wavelength.
The microphone 22 that controlled terminal 20 comprises decoding chip 21 and is connected with decoding chip 21.After microphone 22 carries out coupling reception to above-mentioned ultrasonic signal, then this ultrasonic signal after coupling is converted to the signal of telecommunication and is passed to decoding chip 21.Decoding chip 21 controls controlled terminal 20 according to this signal of telecommunication correspondence.Microphone 22 can be preferably MEMS microphone, also can be that other may correspond to the microphone of received ultrasonic signal.Especially, microphone 22 comprises filter circuit, this filter circuit is set with the thresholding mated with above-mentioned characteristic frequency or specific wavelength, thus, this ultrasonic signal carries out filtering by this filter circuit after being passed to microphone 22, the ultrasonic signal only with this characteristic frequency or specific wavelength by this filter circuit, can realize the match cognization of ultrasonic signal thus.Form the signal of telecommunication after this ultrasonic signals of microphone 22 pairs of characteristic frequency carries out electroacoustic conversion, then carry out subsequent operation by decoding chip 21.The concrete structure of filter circuit with reference to prior art, can not repeat again.
Use above-mentioned ultrasonic identification and control system, according to the control command for different controlled terminal of user's input, control terminal 10 can the corresponding ultrasonic signal generating different frequency, and different ultrasonic signals then identifies coupling by the controlled terminal 20 that correspondence is different further and finally performs corresponding control command.
In the embodiment shown in Fig. 2, control terminal 10 of the present utility model is mobile communication equipment, such as mobile phone, and controlled terminal 20 is then multiple household electrical appliance.Such as, controlled terminal 20 is air-conditioning and TV, and user is by after mobile phone input air-conditioning open command and TV out code, and mobile phone generates according to above-mentioned two instructions the ultrasonic signal that two frequencies are respectively f1, f2 respectively and sends.Air-conditioning and TV are separately installed with can the microphone of received ultrasonic signal, frequency is that the ultrasonic signal of f1 is by air-conditioning identification, frequency be the ultrasonic signal of f2 then by TV identification, thus, user can utilize mobile phone to control corresponding housed device by ultrasonic signal.
The ultrasonic identification that the utility model provides and control system, it generates the control of specific ultrasonic signal realization to corresponding controlled terminal by control terminal, and then simplifies operation, also saves manpower, and has saved cost.
Above-described is only better embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
