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.
