Fig. 2 is the schematic diagram of the utility model dialer.

Fig. 3 is the circuit diagram of the utility model dialer.

Fig. 4 is the working waveform figure of the utility model dialer.

Fig. 5 is the phonetic dialing circuit diagram that the utility model is located at Handless inside.

Relevant basic composition element of the present utility model, see also shown in Figure 1, it mainly is made up of a dialer 10 and a phonetic dialing circuit, wherein the phonetic dialing circuit can be located at existing Handless 20 inside, be connected with automobile cigarette lighter by Handless 20, to obtain working power, constitute line via Handless 20 and mobile phone 30 simultaneously again, to dial.

Wherein dialer 10 is to constitute the signal transmission with the phonetic dialing circuit in wireless and the Handless 20, dialer 10 can be located at the appropriate location in the driver's seat again, to make things convenient for the driver to dial nearby, it can be as shown in Figure 2, dialer 10 is fixed on the steering wheel 40, at this position is set, the driver also need not remove hand steering wheel 40, can be directly with finger dialing on dialer 10, can prevent effectively that whereby the driver from moving the steering wheel 40 and influence traffic safety with hand.

Again about the internal circuit of aforementioned dialer 10, see also shown in Figure 3ly, it includes a coding circuit 11, a matrix keyboard group 12 and a wireless transmitting module 13, wherein:

Coding circuit 11 is made of the integrated circuit of numbering PT-2221, and its oscillator signal input pin OSC1, OSC2 are connected with an oscillating circuit 14 of being made up of two capacitor C 1, C2 and the sub-X1 that vibrates, and provide the sequential oscillator signal of a 455KHz to give coding circuit 11.

Coding circuit 11 is to be connected with matrix keyboard group 12 with pin KI0～KI3, KI/O0～KI/O3.Matrix keyboard group 12 includes 10 sets of numbers keys 0～9, a dialing acknowledgement key (SEND), a clear key (CLEAR), rehearse a key (REPEAT) and an end key (END) etc. at least, operates dialing for the user.

Moreover, coding circuit 11 is to be connected with wireless transmitting module 13 with output connecting pin REM, wireless transmitting module 13 can be made of infrared ray or radio remote control technology, in present embodiment, wireless transmitting module 13 is to be made of an infrared transmitter, and it mainly is to drive an infrared diode 16 by a transistor 15 to be constituted.

The coding circuit 11 of dialer 10 is that when arbitrary button is pressed in the matrix keyboard group 12, coding circuit 11 will give addressing and be encoded into correct transmitting, and be launched by wireless transmitting module 13 with scan mode scan matrix keyboard group 12.

Transmitting includes 32 bit data, and it includes the user code (CUSTOM CODE) of 16 bits, the button data of 8 bits, the button data sign indicating number of 8 bits and the mutual exclusion or the button data sign indicating number of 8 bits, and its work wave as shown in Figure 4.

Microprocessor 20 is to be made of the integrated circuit of numbering 16C55, it is to be connected with a wireless receiving module 24 with input pin RB0, be connected with sound circuit 22 with pin RC0～RC7 again, its output connecting pin RA0 is provided with an output circuit 25 again, go up in input pin RA1 again and constitute a signal input end (DATA IN), so that the circuit by Handless 20 is connected with mobile phone, wherein:

Wireless receiving module 24 is to receive module by an infrared ray to constitute in present embodiment, and wireless receiving module 24 will be removed infra-red carrier after receiving transmitting of dialer 10, decode and send in the microprocessor 21.

Sound circuit 22 is to be that the voice IC of API8108 constitutes by two group #, and its output connecting pin COUT lease making one resistance R 4 and a capacitor C 5 are connected on the loud speaker (not shown) of Handless 20, so that produce the voice corresponding with dialed number.

Output circuit 25 is to be made of a transistor AND gate resistance, mainly is the usefulness of making signal inversion, and its circuit by Handless 20 is connected with mobile phone.

Can find out physical circuit structure of the present utility model by above-mentioned explanation, it is detailed as described below as for its working method: when the driver is dialled by the dialer on the steering wheel 40 10 nearby, whenever by next button, promptly sending one transmits to the phonetic dialing circuit of Handless 20 inside, the microprocessor 21 of phonetic dialing circuit receives that promptly to give decoding behind this signal temporary, and the voice that drive sound circuit 22 selection correspondences are play, when pressing numerical key " 9 " as the driver, promptly corresponding one " 9 " the voice that produce of sound circuit 22 are confirmed for the driver.After having dialled all numerals, the driver can press the key of rehearsing, the phonetic dialing circuit is rehearsed previous dial the number once with voice, for reaffirming, or also can save this and one confirm step, directly pressing dialing acknowledgement key (SEND) makes number sets that the microprocessor 21 of phonetic dialing circuit will before store send to mobile phone with tandem moor via output circuit 26 dialling, can utilize Handless 20 to converse after it is put through.After treating talk-through, the end key (END) that also can press nearby on the dialer 10 can be hung up phone by the phonetic dialing circuit.

Aforementioned phonetic dialing circuit when not receiving dialing confirmation signal (SEND) yet, is promptly abandoned this group dialing after receiving dialing signal one appropriate time (as 10 seconds), come back to standby condition.Moreover the driver dials a wrong number as finding in dialing midway, and the clear key (CLEAR) that can press on the dialer 10 is reset, and restarts dialing.

The utlity model has following effect:

Because the utility model utilizes the dialer that can be located at the driver's seat appropriate location, passes through transmission of wireless signals Cooperate with the phonetic dialing circuit of establishing in the Handless, in the time of can making the driver in driving, need make a phone call, just Nearly handled easily dials, and need not allow hand departure direction dish, during dialing also have simultaneous voice to provide true during operation Recognize, need not divert attention and watch keyboard attentively, so not only can be convenient to dialing, more can guarantee traffic safety.
