Description

Motorcycle anti-theft alarm

The utility model relates to a kind of vehicular electrical appliance, particularly be a kind of motorcycle anti-theft alarm.

Existing motorcycle anti-theft alarm, adopt mercury switch as trigger switch, it is installed in certain location, when the inclination angle, position that motor bike is parked changes, mercury bead in the mercury switch rolls, circuit is switched on or switched off, give energizing signal of warning circuit, make warning circuit send the sound or flashing light alarm signal, this class burglar alarm is simple in structure, easy for installation, and adopt the loudspeaker of motor bike self and car light mostly as the sound and light signal source, this loses the anti-theft alarm signal with regard to being easy to be destroyed.Moreover because this class burglar alarm be must make the inclination angle of vehicle body that directed change takes place the time, mercury switch just can be switched on or switched off, and parallel when mobile if motor bike does not change inclination angle when parking, mercury switch can not trigger, and annunciator was lost efficacy.

The purpose of this utility model will provide a kind of highly sensitive exactly, not limited by the inclination angle, the motorcycle anti-theft alarm that is difficult for being disengaged.

The purpose of this utility model is achieved like this: mobile phone is arranged in the utility model, what cooperate with mobile phone is loaded on main frame on the motor bike, have on the main frame acceptor circuit (51), with acceptor circuit bonded assembly decoding circuit (52), with the decoding circuit bonded assembly contain photoelectric switch (20) microseism binary pair (53), with microseism binary pair bonded assembly transmission circuit (54), have in the mobile phone acceptor circuit (55), with acceptor circuit bonded assembly sound circuit (56), encode circuit (57), with encode circuit bonded assembly transmission circuit (58) (referring to Fig. 1, Fig. 2).

Aerotron (1) is arranged in the acceptor circuit in the above-mentioned main frame (51), resistance (2,3,4), electric capacity (5,6,7,8,9), inductance coil (10,11), resistance (12) is arranged in the decoding circuit (52), electric capacity (13), op amp (14,15), demoder (16), have in the microseism binary pair (53) and photoelectric switch (20) bonded assembly spring (49), place the reflex block (50) at spring top, with photoelectric switch bonded assembly op amp (21,22), coder (26) is arranged in the transmission circuit (54), aerotron (27,78), acceptor circuit in the mobile phone has resistance (30 in (55), 31,32), electric capacity (33,34,35,36), inductance coil (37,38), sound circuit has op amp (39 in (56), 40) with op amp (40) bonded assembly demoder (41), with demoder bonded assembly aerotron (42), be connected to the collecting electrode of aerotron (42) and the loudspeaker (43) between demoder 18 pin, encode circuit has shift knob (44 in (57), 45), coder (46) has in the transmission circuit (58) and coder (46) bonded assembly aerotron (47,48) (referring to Fig. 3～Fig. 5).

Photoelectric switch in the above-mentioned microseism binary pair is reflective photoelectric switch (referring to Fig. 5).

The utility model adopts wireless remote mode, is made up of main frame and mobile phone two parts.Main frame is mounted on the motor bike, is used for shutoff or connection motor bike power supply and sends alerting signal, and mobile phone is to be with on one's body the car owner, is used for remote host mode of operation and reception alerting signal.As shown in Figure 1.The host work state is set by mobile phone, the remote signal of coming when the mobile phone emission receives by acceptor circuit, decoding circuit decoding identification, in this way the early warning order then decoding circuit will make the microseism binary pair be in alert status, startup power supply simultaneously kills engine, at this moment, as long as motor bike has the slight vibrations of any direction, will make the microseism flip-flop operation, it will be defeated by the transmission circuit energizing signal, make transmission circuit work, outwards launch specific wavelength and encoded electromagnetic wave, mobile phone is after receiving the electromagnetic wave of this specific wavelength, by the decoding identification of mobile phone, send too, the very brief audible indication of pouting reminds owner to have the people to move motor bike.Because the sound and light alarm signal is not set on main frame, just report to the police in the strange land of radiowave transmission, and this just makes this type of alarm have great fascination and disguise, is difficult for finding, helps arresting the burglar.As shown in Figure 2, the acceptor circuit in the mobile phone is specifically designed to the alerting signal that receives the main frame emission, and by decoding identification, if the pairing host signal, then decoding makes sound circuit work, sends alarm sound, encode circuit is to be used for setting the host work state, and promptly main frame is to cut out or early warning.When motor bike need be parked, then press the early warning code switch in the encode circuit, then encode circuit will be exported a series of pulses and make transmission circuit emission modulated electric wave, make main frame be in alert status, and startup power supply simultaneously kills engine.When motor bike need be walked, then press the code switch of closing in the encode circuit, then encode circuit will be exported a series of pulses and make transmission circuit emission modulated electric wave, make main frame be in closed condition, open the driving engine power supply simultaneously, motor bike can the normal starting walking.
