Abstract
The invention provides an ultrasonic feedback automobile key and belongs to the field of electronic communications. The ultrasonic feedback automobile key comprises a trigger switch, a modulator, a transmitter, a receiver and a buzzer, wherein after a signal is received by the receiver, the buzzer is triggered to generate ultrasonic waves. The position of the automobile key can be tracked by a mobile phone; and the ultrasonic feedback automobile key has a simple structure.
Description
Technical field
The present invention relates to electronic communication field, particularly, relate to a kind of automobile key with communication function.
Background technology
Along with the surge of automobile quantity, automobile key has become the carry-on articles in people's daily life gradually.And with the quickening pace of modern life, people are for the memory of trival matters also variation gradually; In busy work and life process, often can not note the placement part of automobile key, when needs are driven, often can seek for a long time and just can find automobile key, this will cause very large inconvenience to the people, troublesome not only, and lose time in a large number.
Under the circumstances, can according to the method for searching mobile phone in the daily life, to the automobile key transmitted signal, and it be piped, thereby it is found.Yet the volume of automobile key is very limited, and for buzzer, and the too small buzzer volume of volume is very little, when automobile key is placed in the clothing heap, if also there is the component environment noise, can't hear the sound of buzzer at all; For the larger buzzer of volume, then can't arranged rational in the small size automobile key.Therefore, for a kind of traceable automobile key of invention, be extremely to have practical significance at present.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of ultrasonic reaction type automobile key, this automobile key can adopt its position of mobile phone tracking, and simple in structure.
The technical solution adopted for the present invention to solve the technical problems is: this ultrasonic reaction type automobile key comprises: trigger switch, modulator, transmitter; Also comprise receiver, buzzer; After described receiver receives signal, trigger described buzzer and generate ultrasonic wave.
The present invention also aims to provide a kind of cell phone software method that described ultrasonic reaction type automobile key is communicated tracking, the method comprising the steps of:
One, sends trace signals; Begin simultaneously timing: sent the signal that equates with the receiver resonant frequency of described automobile key by antenna for mobile phone, timer begins timing simultaneously;
Two, wait for feedback signal: monitor the ultrasonic wave feedback signal that the buzzer of described automobile key sends by the receiver of mobile phone;
Three, receiving feedback signals; Finish simultaneously timing: the receiver by mobile phone receives described ultrasonic wave feedback signal, and is converted to analog signal, and this analog signal triggering timing device stops timing;
Four, calculate the automobile key distance: finish the time of getting of counting according to beginning timing to timing, and SVEL, i.e. 340m/s calculates the distance of automobile key;
Five, display automobile key position information: the positional information of display automobile key on mobile phone screen.
Beneficial effect of the present invention is: when this ultrasonic reaction type automobile key is lost within the specific limits, that is the user forget its placement local time, by common smart mobile phone, behind the software that installation is write according to above-mentioned software approach, can find easily automobile key by communicating by letter between mobile phone and the automobile key.
Description of drawings
Fig. 1 is the structural representation of this ultrasonic reaction type automobile key.
Fig. 2 is an embodiment schematic diagram that ultrasonic reaction type automobile key shown in Figure 1 is carried out the software approach of mobile phone tracking.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
The electrical structure of an embodiment of ultrasonic reaction type automobile key provided by the invention as shown in Figure 1, it comprises: trigger switch 1, modulator 2, transmitter 3; Described trigger switch 1 triggers modulator 2 and modulates corresponding control signal, sends by transmitter 3, with operations such as control opening/closing door of vehicle; This automobile key also comprises receiver 4, buzzer 5; After described receiver 4 receives signal, trigger described buzzer 5 and generate ultrasonic wave.
Realize the cell phone software method that communication is followed the trail of for ultrasonic reaction type automobile key shown in Figure 1, an one embodiment comprises following step as shown in Figure 2:
Send trace signals S110: sent the signal that equates with receiver 4 resonant frequencies of described automobile key by antenna for mobile phone; Simultaneously, beginning timing S120;
Wait for feedback signal S130: monitor the ultrasonic wave feedback signal that the buzzer 5 of described automobile key sends by the receiver of mobile phone;
Receiving feedback signals S140; Simultaneously, finish timing S150: the receiver by mobile phone receives described ultrasonic wave feedback signal, and is converted to analog signal, signal spectrum default in this analog signal and the software is compared, and both are consistent, then confirm as the feedback signal that automobile key sends, at this moment, timer stops timing;
Calculate automobile key apart from S160: finish the time of getting of counting according to beginning timing to timing, and SVEL, i.e. 340m/s calculates the distance of automobile key; Concrete computational process is as follows: establishing the time of getting of counting is t, and the velocity of sound is v, and then automobile key is apart from the distance L=vt/2 of mobile phone.
Display automobile key position information S170: the positional information of display automobile key on mobile phone screen; Its display mode can comprise following two kinds: one, only range of a signal data on screen; Its two, show one take mobile phone location as the center of circle at screen, the distance L of automobile key is the circle of radius, shows simultaneously this radius of a circle.
In addition, before step S110, also comprise a step: generate timing pip S100; This step S100 (comprises step S110 and step S170) so that mobile phone, repeats step S110 every an equal time interval in steps to the institute between the step S170.
When above-mentioned ultrasonic reaction type automobile key is lost within the specific limits, by common smart mobile phone, the software that moves according to above-mentioned software approach is installed after, can obtain easily the positional information of automobile key.Particularly, under the triggering of described step S100, by mobile phone continuously to the automobile key transmitted signal, and receiving feedback signals continuously, in this process, the user moves towards the direction of automobile key Distance Shortened all the time, can move closer to automobile key, it finds the most at last.
It is worthy of note at last, for present common smart mobile phone, the function that all has signal transmitting and receiving, the reception of various audio frequency and process, therefore, can be competent at above-mentioned software approach fully, those skilled in that art only need according to the step making software in the above-mentioned software approach, can realize following the trail of to automobile key; For the particular content of software, not the object of patent protection on the one hand, belong on the other hand software engineer's common-sense technology contents, repeat no more herein.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
