In the specific working process of the burglar alarm, the vibration sensor SW2 is in an open circuit state when not detecting vibration, a passage is formed when the vibration sensor SW2 detects vibration, the level of the pin A4 of the chip U4 is lowered, the chip U4 can finish the acquisition of a vibration alarm signal according to the level change of the pin, and then a horn is started through the pin A2 or the pin A3 to perform sound alarm.

In a defense state, a pin B1 of the chip U4 is at a high level to enable the triode Q11 to be conducted, and further a motor locking signal wire of a target vehicle is conducted, so that the motor locking function of the target vehicle is started, and the motor is prevented from rotating. When the wheels of the vehicle rotate, a controller wheel-motion signal line of the vehicle can output a 5V signal, the signal enters a wheel-motion monitoring module and then passes through voltage division of a resistor R36 and a resistor R37 and filtering of a capacitor C16, so that the base electrode of the triode Q18 has voltage, the triode Q18 is conducted, the level of the A1 pin of the chip U4 is pulled down, and the chip U4 can monitor the wheel motion through the level change of the pin. When a wheel movement signal is monitored in a fortification state, the chip U4 starts a horn through the A2 pin or the A3 pin to carry out sound alarm.

This wireless receiving module can receive 433 MHz's signal, and it can match with the remote controller in advance, and wireless receiving module sends the signal that comes from the remote controller to chip U4 and decodes, can know the concrete button that the remote controller pressed according to advance matching, and then discerns user's operation, makes corresponding processing. The matching between the remote controller and the receiving end is a conventional technical means in the field and is not described herein.

When the pin B2 of the chip U4 outputs a high level, the triode Q17 of the power supply and sound production module is conducted, the relay JK1 works to enable the pin 3 and the pin 4 to be communicated, further the active switch SW1 is electrified and works, the active switch SW1 works and connects the control signal receiving end of the vehicle power component and the control signal sending end of the vehicle power component, so that the control signal of the vehicle can work normally, and the normal use state of the vehicle is recovered. When the pin B2 of the chip U4 outputs a low level, the triode Q17 is not conducted, the relay JK1 does not work, the active switch SW1 does not work, the control signal receiving end of the vehicle power component and the control signal sending end of the vehicle power component are in open circuit, and the vehicle cannot be normally used. When the relay JK1 works, the start feedback end of the power supply and sound production module feeds back the working condition of the power supply and sound production module to the chip U4, and if the working condition of the power supply and sound production module is abnormal, the chip U4 can start the horn through the A2 pin or the A3 pin to perform sound alarm.

As long as the power supply and the sounding module are connected with the power supply inlet wire of the vehicle, the power supply end of the power supply and the sounding module can output corresponding voltage outwards, and meanwhile, the loudspeaker is in a standby state. The chip U4 can generate related duty ratio pulses to drive the horn through the A2 pin and the A3 pin, so that the horn has 2 alarm sounds and can correspond to different dangerous cases.

In an embodiment of the utility model, if use the object to be the vehicle that the engine is power parts, then can regard as vehicle power parts's control signal receiving terminal and sending end with the both ends of the power supply line of this vehicle engine's ignition coil, two interfaces that are about to active switch SW1 controlled end are established ties between ignition coil and ignition coil power supply device, make ignition coil power supply device's electric energy need can reach ignition coil through active switch SW1, make active switch SW1 under normally open state, ignition coil does not energize, and then make the unable work of driving system of this vehicle. If the vehicle with the motor as the power component is used, two interfaces of the controlled end of the active switch SW1 can be connected in series in a motor control signal line or a power supply line, so that the motor is not electrified when the active switch SW1 is in a normally open state, and a power system of the vehicle cannot normally work.

In the first embodiment, when the chip U4 receives the signal of the control signal, the signal is stopped being sent to the power supply and sound generating module, the two controlled ends of the relay JK1 are in the open circuit state, at this time, the relay JK1 stops supplying power to the active switch SW1, the two controlled ends of the active switch SW1 are also in the open circuit state, and the power component of the target vehicle cannot receive the corresponding control signal, so that the power system of the target vehicle cannot normally operate. Taking the electric bicycle as an example, even if a lawbreaker switches on the main power supply of the electric bicycle, the electric bicycle cannot be normally ridden. Since pushing electric bicycles draws the attention of passers-by and police, the lawbreakers often give up theft at this time. Even if lawbreakers still want to steal the electric bicycle, the vehicle owner and the police can quickly find the theft through the roadside video monitoring system to recover the stolen vehicle due to the extremely low pushing efficiency.

When chip U4 received the signal that sound was set up defences, chip U4 sent the signal to vibration monitoring module, when vibration monitoring module sensed the touching and rocked, it sent the signal to chip U4, and chip U4 starts loudspeaker and then makes loudspeaker work realize audible alarm.

When the chip U4 receives a signal of searching for a vehicle, the chip U4 starts a horn to work, and the direction of the vehicle can be obtained in a sound guiding mode.

When the vehicle burglar alarm is in the states of sound fortification and control signal control, if the vehicle needs to be restored to the normal state, the vehicle can be restored to the normal state only by sending a signal for removing the sound fortification to the chip U4 and then sending a signal for removing the control signal to the chip U4.

In this embodiment, the remote controller needs 5 keys to generate 5 different signals, so as to respectively correspond to the signal of the management and control signal, the signal of the sound fortification, the signal of the car searching, the signal of the sound fortification removing, and the signal of the management and control signal removing.

In the second embodiment, since the number of the remote control buttons in the first embodiment is relatively large, in order to reduce the number of the remote control buttons in the first embodiment, the signal for releasing the sound fortification and the signal for controlling the control signal may be set as the same signal, and the signal is triggered by the same button, and at this time, the remote control only needs 4 buttons. If the trigger key of the sound fortification signal is set as the key 1, the trigger key of the sound fortification removing signal and the control signal is set as the key 2, the trigger key of the sound fortification removing signal is set as the key 3, the trigger key of the vehicle searching signal is set as the key 4, the key 2 can be pressed to only control the vehicle through control signal control, and if sound anti-theft is needed, the key 1 is pressed. When the sound theft prevention needs to be relieved but the control signal control is reserved, the key 2 is pressed again.

When the vehicle is only in the control signal management and control state, the normal state of the vehicle can be recovered only by pressing the key 3. When the vehicle is in the control signal management and control state and the sound fortification state at the same time, the normal state of the vehicle can be recovered by firstly pressing the key 2 and then pressing the key 3.

In the above embodiment, the burglar alarm can realize independent start of sound fortification and control signal fortification, and the problem of burglar alarm of the vehicle burglar alarm caused by severe weather can be avoided by independently closing the sound fortification. In addition, if a lawbreaker cuts off the external power supply of the burglar alarm, the power system of the vehicle cannot work normally, so that the vehicle can be recovered to a normal state only after the chip U1 receives a corresponding signal from a matched remote controller, and therefore, the burglar alarm solves the problem that the vehicle is stolen in the normal state after the lawbreaker violently destroys the burglar alarm.
