GPS is new generation satellite navigation and the navigation system that a cover has the navigation of comprehensive real-time three-dimensional and stationkeeping ability in sea, land and sky.Use through the numerous specialized departments in the more than ten years whole world shows, distinguishing features such as that GPS has is round-the-clock, high accuracy, automation, high benefit.Yet,, need special client device to use though GPS is powerful; This is unfavorable for its popularizing in extensive crowd; Even in electronic products such as some high-end mobile phones, notebook computer, use, also need dispose special GPS chip, cost is higher.
Radio-frequency (RF) tag (RFID) location technology can be arranged in the specific region by user oneself and position, for example parking lot, skifield etc.After radio frequency label read-write machine was laid in these regional localities (for example crucial gateway), system can detect the residing position of the object that has the RFID label in real time.Though this location technology need not the cooperation of satellite or cell phone network, its accuracy is the distribution of rfid interrogator and RFID label, the higher and layout inconvenience of system equipment cost.
In sum, existing location technology exist equipment cost high, arrange inconvenience, be unfavorable for the problem popularized.
Summary of the invention
The purpose of this invention is to provide a kind of portable terminal ultrasonic communication system and method, with solve existing location technology exist equipment cost high, arrange inconvenience, be unfavorable for the problem popularized.
The present invention proposes a kind of portable terminal ultrasonic communication system, comprises at least one supersonic generator and at least one portable terminal.Supersonic generator is arranged on ad-hoc location, is used to send the ultrasonic wave that modulates data parameters in advance; The ultrasonic wave that the demodulate reception that is used for portable terminal arrives, and obtain the information that presets.Portable terminal further comprises microphone and demodulation module again; Microphone is used to receive the ultrasonic wave that supersonic generator sends; Demodulation module links to each other with microphone, and the ultrasonic wave that is used for that microphone is received carries out the waveform reduction, and demodulates the data that preset in the ultrasonic wave.
Preferably, portable terminal is a mobile phone.
The present invention proposes a kind of portable terminal ultrasonic communication method in addition, and may further comprise the steps: (1) is provided with at least one supersonic generator.(2) portable terminal receives the ultrasonic wave that this supersonic generator sends, and said ultrasonic wave is loaded with the data that modulate in advance.(3) portable terminal carries out the waveform reduction to the sound wave that receives, and demodulates the data that preset in the ultrasonic wave.
Preferably, portable terminal is a mobile phone.
Preferably, described portable terminal ultrasonic communication method also comprises step: the data that the portable terminal utilization demodulates from ultrasonic wave, carry out the calculating of relevant information through terminal itself or network.
With respect to prior art, the invention has the beneficial effects as follows:
1, the present invention utilizes ultrasonic wave to communicate; Because ultrasonic wave has good directionality; Penetration capacity is strong; Be easy to obtain the characteristics of concentrated acoustic energy; Be particularly suitable for the transmission of data in the occasion of large contingents such as market, exhibition; And ultrasonic wave can not heard by people's ear, effectively avoid noise pollution.
2, portable terminal of the present invention can adopt the existing electronic product that has microphone like mobile phone etc., need not to increase unnecessary hardware device, with low cost, arrangement convenience, and have very high flexibility and adaptive capacity.
Description of drawings
Fig. 1 is a kind of embodiment Organization Chart of portable terminal ultrasonic communication of the present invention system;
Fig. 2 is a kind of embodiment flow chart of portable terminal ultrasonic communication method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, specify the present invention.
See also Fig. 1; It is a kind of embodiment Organization Chart of portable terminal ultrasonic communication of the present invention system; It comprises at least one supersonic generator 1 and at least one portable terminal 2; Supersonic generator 1 is arranged on ad-hoc location; Be used to send the ultrasonic wave that modulates in advance; Ad-hoc location described here is meant the place that the user need communicate or locate; Then be loaded with the data that modulate in advance in the ultrasonic wave that sonic generator 1 is sent; For example ad-hoc location can be the shops in market or the stand of exhibition etc.; Then can be loaded with distance in the ultrasonic wave; Angles etc. are used for locative data or ID, perhaps shops; Stand information etc.
The ultrasonic wave that the demodulate reception that is used for portable terminal 2 arrives; And obtain the information that presets in the ultrasonic wave; Portable terminal 2 comprises microphone 3 and demodulation module 4; Microphone 3 is used to receive the ultrasonic wave that supersonic generator 1 sends; Demodulation module 4 links to each other with microphone 3; The ultrasonic wave that is used for that microphone 3 is received carries out the waveform reduction, and demodulates the data that preset in the ultrasonic wave.
The portable terminal 2 preferred mobile phones that adopt of the present invention.Because the popularization of mobile phone; Make system of the present invention be particularly suitable for the occasion of large contingents such as market, exhibition; And because mobile phone all carries microphone; And hyperacoustic reduction demodulation function can be realized through the process chip installation application software that carries for mobile phone; Promptly with mobile phone as portable terminal 2 after; Need not the hardware of mobile phone is made any change, thereby can practice thrift a large amount of equipment costs.And at present; Mostly the application of mobile phone is by transmitting terminal the sound wave that sends in people's mouth to be converted to the signal of telecommunication; Be the sound wave that people can hear by receiving terminal with electrical signal conversion again; So with mobile phone application in system of the present invention; Utilize mobile phone to receive ultrasonic wave; It is a kind of new application of mobile phone; Can utilize the original function of mobile phone; To directly on display screen, show after the demodulates information that be loaded with in the ultrasonic wave; Perhaps convert radio transmitting to and give other mobile phone; The network calculations of perhaps utilizing this information to be correlated with, thus the flexibility and the adaptive capacity of system of the present invention can be improved greatly.
