Radio frequency type electromobile anti-theft alarm

Abstract

The invention discloses a radio frequency type electromobile anti-theft alarm which comprises a resistor R2 and a diode D1. The output end of the resistor R2 is connected with the anode of the diode D1. The input end of the resistor R2 is connected with the positive pole of a main power source VCC. The radio frequency type electromobile anti-theft alarm further comprises a relay K1. The coil input end 1 of the relay K1 is connected with the anode of the diode D1. The coil output end 2 of the relay K1 is connected with the negative pole of the main power source VCC. The armature input end 3 of the relay K1 is connected with the cathode of the diode D1. The armature output end 4 of the relay K1 is connected with a buzzer U1 in series. The negative pole of the diode D1 is connected with a capacitor C1 or a charging battery. The anti-theft alarm further comprises a vibration alarm apparatus assembly. A wire between the vibration alarm apparatus assembly and the main power source is a main power source wire, and a wire between the input end of the resistor R2 and the positive pole of the main power source VCC is the same wire as the main power source wire. The radio frequency type electromobile anti-theft alarm has the advantage that an alarm can be given out quickly after the main power source wire is intercepted.

Description

technical field [0001] The invention relates to anti-theft alarm technology, in particular to a radio-frequency anti-theft alarm for battery cars. Background technique [0002] With the maturity of the battery car technology, the battery car has become a common tool for people to travel, and the theft of the battery car has always been a social phenomenon that plagues people. There are many existing anti-theft measures, one is to lock the anti-theft, lock the motor, Tire locking is the most commonly used anti-theft method, but this type of anti-theft method still cannot stop illegal personnel with superb unlocking skills. The other type is electronic alarm technology, which uses a vibration sensor to detect the vibration of the car body and sends out an alarm. The alarm means is to connect the alarm component to the battery or the distributor of the battery car to continuously supply power to the alarm, and the alarm component will continue to work. Once the wire between...

[0002] With the maturity of the battery car technology, the battery car has become a common tool for people to travel, and the theft of the battery car has always been a social phenomenon that plagues people. There are many existing anti-theft measures, one is to lock the anti-theft, lock the motor, Tire locking is the most commonly used anti-theft method, but this type of anti-theft method still cannot stop illegal personnel with superb unlocking skills. The other type is electronic alarm technology, which uses a vibration sensor to detect the vibration of the car body and sends out an alarm. The alarm means is to connect the alarm component to the battery or the distributor of the battery car to continuously supply power to the alarm, and the alarm component will continue to work. Once the wire between the alarm component and the battery power supply is cut off, the alarm component will not work. Therefore The alarm component became a useless alarm component
