Embodiment
Below in conjunction with accompanying drawing and preferred embodiment,, specify as follows structure, characteristic and the effect thereof of the utility model:
As shown in Figure 1; The utility model provides a kind of electronic scales; Comprise apparatus main body and measured body weight module and DTMF modular converter; DTMF modular converter and audio frequency transmitting element, DTMF modular converter are used for that the weight data that the measured body weight module is exported is carried out dtmf tone encodes frequently, converts corresponding dtmf tone audio data and output into; The audio frequency transmitting element links to each other with the output terminal of DTMF modular converter, is used for converting the dtmf tone audio data of DTMF modular converter output into carry dtmf tone frequency information voice signal.The audio frequency transmitting element comprises block isolating circuit, driving circuit and the loudspeaker that links to each other successively, and block isolating circuit links to each other with the output terminal of DTMF modular converter.
The DTMF modular converter of the utility model is made up of single-chip microcomputer (being CPU on the figure) and peripheral components thereof; The DTMF voice document that records is stored in single-chip microcomputer inside; After the IO mouth output of dtmf tone audio data that is converted to by single-chip microcomputer operation converse routine, convert the voice signal that has carried DTMF information into through the audio frequency transmitting element by single-chip microcomputer.The audio frequency transmitting element comprises block isolating circuit, loudspeaker driving circuit and the loudspeaker several sections that connects successively.Concrete principle of work is following:
Single-chip microcomputer reads in data in the internal memory after receiving the measured body weight data that need to send, and the service data converse routine becomes corresponding dtmf tone audio data with the data-switching that receives, and is stored as the DTMF voice document.Single-chip microcomputer is that the PWM ripple of 32khz sends to block isolating circuit with data through the IO mouth with the cycle then; By block isolating circuit data are carried out passing to the loudspeaker driving circuit part after the filtering; Data are amplified, through loudspeaker dtmf tone frequency signal is sent then.The time of playing a dtmf tone is 100 milliseconds, and utilizing the duration is that 120 milliseconds quiet separated two continuous dtmf tone data.Defining a dtmf tone is start bit, at first plays this data bit before the played data.
The mobile device that the utility model provides a kind of this kind of short distance reception to carry the voice signal of DTMF information simultaneously referring to Fig. 2, comprises receiving element, mobile device CPU and weight data output device.Wherein, receiving element is used to receive the voice signal that carries dtmf tone frequency information by electronic scales output; Mobile device CPU is used for the voice signal that carries dtmf tone frequency information that receiving element receives is decoded, and extracts weight data, and through weight data output device output weight data.
The mobile device of the utility model embodiment is mobile devices such as mobile phone; Mobile phone need be opened the sound pick-up outfit that carries before receiving, mobile phone utilizes the sound pick-up outfit received speech signal, after receiving the start bit voice; Bring into use decoding program that follow-up data is decoded; The time of a speech data of decoding is 17ms, and the dtmf tone of 1 lasting 100ms can be decoded and obtained 5 data bit, if identical data is more than or equal to 3 then think that the data that the dtmf tone of this lasting 100ms loads are these identical datas in 5 data; So just played jamproof about, idiographic flow can be referring to Fig. 3.Mobile phone receives data designated quantity, stops to receive data.Reception finishes after the data, and data will be stored in the memory inside of mobile device 9.After mobile device can use specific data processing software carry out secondary treating to these data, through the weight data output device, i.e. output device such as display screen, loudspeaker, with vision, means such as the sense of hearing pass to the user.
