Description

Computer electronic alarm for motorcycle

The utility model belongs to electronic technology field, relates to the alarm and the electronic machine that amplifies on a kind of public security, the special-purpose motor bike of traffic.

At present, the siren horn on the various two-wheeled police motorcycle cars have only single alert conditioning function, and volume is unadjustable, no warning lamp, and alarm function conversion, volume are regulated, the function that speech amplifies; The automobile-used siren horn of various three-wheel police motorcycles also can only be contained in siren horn in the car sidecar, and various control operations chaufeur in driving can't be operated, and siren horn all is made up of digital circuit and discrete component simultaneously, and alert frequency is inaccurate, unstable, modified tone.

The purpose of this utility model provides a kind of special-purpose siren horn of motor bike that adopts the special construction of one chip microcomputer control, it is installed in the left handlebar of various police motorcycle cars near handle end, chaufeur just can carry out alarm, warning lamp, volume control in driving, join throat microphone outward or helmet transmitter also can be propagandaed directed to communicate in driving.

The utility model know-why is as follows:

Circuit diagram is shown in Fig. 1 block diagram, and it is by control circuit, microphone audio amplifying control circuit, volume control circuit, and audio power amplifying circuit, horn speaker is formed.The various controllable function of siren horn are controlled by micro controller system internal program software.

IC1 micro controller system the 14th pin connects+the 5V power supply, 5 pin ground connection, 1st, 2 pin are respectively by R1, R2, resistance connects+the 5V power supply, and 2 by switch NK1, NK2 ground connection, forms key circuit, IC1 the 4th pin is received on R3 resistance and the C1 capacitances in series node by resistance R 4, R3 is termination+5V power supply in addition, and C1 holds ground connection in addition, forms the last reset circuit of IC1.The 15th of IC1, the indirect AJ quartz crystal oscillator circuit of 16 pin passes through C2 again respectively, C3 ground connection, the external clock oscillating circuit of forming IC1, IC1 the 6th pin is the alarm signal mouth, connect+the 5V power supply by R5, receive fader spare IC2 the 4th pin by C4 series connection R6 again, IC1 the 7th pin is a microphone conversion and control end, it receives T1 switch triode base stage by R11, connect+the 5V power supply by R12 again, R13 connects+5V power supply and T1 collecting electrode between, H microphone socket one end ground connection, termination T1 collecting electrode in addition, send the 4th pin of fader spare IC2 simultaneously by C6 series connection R14, when IC1 when low voltage 0.7V is following, T1 ends, the nearly 5V voltage of T1 collecting electrode, during the external Electret condenser microphone of this machine, R3 becomes microphone to biasing resistance, and C6 is the microphone output capacitance, can pick up voice signal to microphone and send volume control circuit IC2, send IC3 audio power amplifying circuit by the IC2 gating again, when IC1 the 7th pin high potential near+during 5V voltage, T1 is saturated, the nearly 0V microphone of collector voltage does not have bias current, there is not signal output, so the conversion of IC1 the 7th pin may command earphone function.The 13rd, 12,11 pin of IC1 connect the 11st, 10,9 pin of IC2, IC2 eight selects a simulant electronic switch, IC2 the 16th pin power connection, IC2 the 4th pin is by R7, R8, R9, R10 series resistance grid grounding, IC2 the 1st pin connects R7, R8, series connection node, and the 14th pin connects R8, R9 series connection node, and the 13rd pin connects R9, R10 series connection node, 6th, 7,8 pin ground connection, the 3rd pin connects audio power amplification path the 1st pin input end by C5 capacitances in series C8 electric capacity.In volume control, make IC1 the 13rd like this, 12,11 pin voltages are uprised by low, make IC3 the 3rd pin to the 13rd, 14,1,4 pin conductings, alarm or the microphone signal sent into by R6 or R14 can send the 3rd pin of IC2 to audio power amplifying circuit by resistance network, IC3 the 1st pin connects incoming signal by C8, the 2nd, 3 pin pass through C10, C11 ground connection, the 4th pin ground connection, the 5th, Y1 is sent in the output of 6 pin, the external horn speaker of Y2, the indirect C14 of bipod, pass through C13 respectively, C12 ground connection, IC3 the 7th pin connects+14V, and by C9 ground connection, IC4 is+5V three-terminal voltage-stabilizing circuit, the 1st pin connects+14V, the 2nd pin ground connection, the 3rd pin is by C7 ground connection, output+5V voltage, D1, D2 is the motor bike power input, K1 is the siren horn source switch, and K2 is the warning lamp source switch, can send warning lamp power line voltage by D0.

The appearance structure of this siren horn control part has upper shell 1 and lower house 5, the fixedly screw 7 of two housings is arranged in the housing back, button 2, switch 3 and microphone socket 4 are arranged in the housing front, circuit card 6 is fixed in the upper and lower two housings, in the middle of the two housings circular hollow is arranged, the circular hollow diameter equates with the motorcycle handlebar diameter of steel tube.

The utility model advantage is: appearance structure is reasonable, compact, and circuit is simple, practical, and chaufeur just can be used and the operational alarm device in driving.
