Electric bicycle anti-theft alarm control circuit

Abstract

The invention comprises multiple electrolytic capacitors C1, a ceramic capacitor C2, an electrolytic capacitor C3, an electrolytic capacitor C4, an electrolytic capacitor C5, an electrolytic capacitorC6, an ceramic capacitor C7, an ceramic capacitor C8, a diode D1, a diode D2, a diode D3, a diode D4, a NPN triode Q1, NPN triode Q2, a NPN triode Q3, a precision level conversion chip U1, a NOT gateU2, an OR gate U3, a comparator U4, a time base circuit U5, a 12 volt relay RL1, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a resistor R8, a resistor R9, a resistor R10, a resistor R11, buzzer BUZ1 and a high brightness LED. The control circuit can judge whether the electric bicycle has been stolen according to the key-on state or themovement state. If the electric bicycle is stolen, it will give out sound and light alarm and let the motor lock to prevent being forcibly pushed away; the electric bicycle remote control or other wireless communication can also be used to remotely control the electric bicycle control panel and shut down the electric motor and lock the motor.

Description

technical field [0001] The invention relates to an electric bicycle anti-theft alarm control circuit. Background technique [0002] The theft of electric bicycles is very common at present. The technologies adopted by electric bicycle manufacturers include locking the faucet, sending out sound and light alarms when being collided, and locking the motor. These technologies are indeed very effective when the thief does not have a master key to open the electric car, but when the electric car is stolen, the thief often has the technology of quick unlocking or the master key, so that once the faucet lock is opened, the electric car is basically locked. There are no more defenses. Obviously we need a technology that can automatically defend the electric car after it is driven to prevent it from being stolen. Contents of the invention [0003] In order to solve the above problems, the present invention provides an electric bicycle anti-theft alarm control circuit. This circui...
