Description

A kind of automobile anti-theft remote controller with the cell phone incoming call demonstration

The utility model relates to a kind of automobile anti-theft remote controller with the cell phone incoming call demonstration.

The existing domestic cell phone mobile telephone phone ratio that uses per capita is quite high, but in meeting, public situation such as see a film, the incoming call of mobile telephone is very tedious noise.

The purpose of this utility model provides a kind of automobile anti-theft remote controller with the cell phone incoming call demonstration, and it can be with mobile telephone caller identification installing additional on the display lamp at the automobile remote-control device.

For achieving the above object, the utility model is taked following design plan: the automobile anti-theft remote controller that this band cell phone incoming call shows, constitute by automobile anti-theft remote controller, comprise band display lamp and the body skin of function key and built-in remote controller keying line, in the remote controller keying line, add a mobile phone caller identification circuit, this cell phone incoming call display circuit comprises coil-induced group an of receive frequency, one triggers demodulating unit, one electronic switch unit, the input of demodulating unit is sent out in the output contact that receive frequency is coil-induced group, the output that triggers demodulating unit connects the input end of the display lamp LED of remote controller keying line, and the input control end of demodulating unit is sent out in the transistor emitter output contact of electronic switch.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present utility model (cuts open, side, front view)

Fig. 2 is a circuit principle structure scheme drawing of the present utility model

The utility model is based on existing automobile anti-theft remote controller improvement and forms.

As shown in Figure 1, the utility model physical construction has adopted the basic structure of existing automobile anti-theft remote controller, is not repeated herein.

Of the present utility model being characterised in that done improvement to the master control circuit, as shown in Figure 2, it is to add one group of cell phone incoming call circuit (the fine rule route is the keying line of prior art automobile anti-theft remote controller among the figure, the cell phone incoming call display circuit of thick line route for adding) in the keying line of former automobile anti-theft remote controller.

The keying line of automobile anti-theft remote controller comprises that a high frequency produces signal element and a receiving lines, and wherein U1 is the frequency coding integrated circuit block, is prior art, is not repeated herein.

The group of received mobile phone signal frequency coil sense group (by resistance R ' 1-R ' 6 and aerotron Q ' 1, capacitor C ' 1, C ' 2, diode D ' 1 form), one that comprises the cell phone incoming call display circuit triggers demodulating unit (resistance R ' 7-R ' 12, capacitor C ' 3, C ' 4, separate frequently that oscillating integrated circuit piece U ' 1, trigger action aerotron Q ' 2 form), an electronic switch unit (SW ' 1 and aerotron Q ' 3 compositions).Wherein the input of demodulating unit is sent out in the output of coil-induced group of receive frequency contact, the input of the display lamp LED of the former remote controller of output termination of trigger action aerotron Q ' 2, the emitter output of the aerotron Q ' 3 of electronic switch connect separates the input control end 8 of oscillating integrated circuit piece U ' 1 frequently.

Its principle of work is: the work that electronic switch is controlled the cell phone incoming call acceptor circuit whether, aerotron Q2 ' ends at ordinary times, after receiving the mobile phone ultra-high frequency signal, pulse high level energizing signal of Q2 ' base stage is exported in demodulation, makes display lamp LED glittering.Inform the master cellular phone incoming call.

It promptly has the effect of automobile anti-theft remote controller like this, has the function that cell phone incoming call shows again concurrently, owing to be that the flashing light prompting makes that to need quiet occasion to use at some convenient more.

The utility model has the advantage of: automobile anti-theft remote controller and cell phone incoming call are shown that the two function is combined into One has namely been saved spent cost has been set separately, and use is more convenient.

Claims (1)

1, a kind of automobile anti-theft remote controller with the cell phone incoming call demonstration, constitute by automobile anti-theft remote controller, comprise band display lamp and the body skin of function key and built-in remote controller keying line, it is characterized in that: in the remote controller keying line, add a mobile phone caller identification circuit, this cell phone incoming call display circuit comprises coil-induced group an of receive frequency, one triggers demodulating unit, one electronic switch unit, the input of demodulating unit is sent out in the output contact that receive frequency is coil-induced group, the output that triggers demodulating unit connects the input end of the display lamp LED of remote controller keying line, and the input control end of demodulating unit is sent out in the transistor emitter output contact of electronic switch.
