After electric motor car comes to a complete stop, user needs to lock electric motor car.After the fingerprint of oneself is correctly entered by user, the
It is consistent with at least one fingerprint image sample that one microprocessor identifies this fingerprint image, then send a series of pulse train extremely
Second microprocessor, after the second microprocessor identification lock power tube unit, i.e. will not to power tube unit output drive signal,
Then power tube unit can quit work owing to not driving signal, controls lithium battery further and stops power supply, thus electric motor car
Will be unable to travel.
When user needs to open electric motor car, need to re-enter fingerprint.After the fingerprint of oneself is correctly entered by user, the
It is consistent with at least one fingerprint image sample that one microprocessor identifies this fingerprint image, then first microprocessor is to second micro-place
Reason device sends the pulse train calculated by dynamic encryption algorithm, at the second microprocessor by identical dynamic encryption algorithm
