Abstract

An intelligent entrance guard unlocking method includes: transmitting electric energy of a power unit of a intelligent entrance guard in a wireless electromagnetic radiation via a transmit coil; receiving the electric energy via a receiver coil of a powerless smart key; capturing a palm print image and storing the palm print image in a second storage unit of the powerless smart key; controlling a wireless transmit unit of the powerless smart key to transmit a wireless signal containing the palm print image to the intelligent entrance guard; obtaining a predefined palm print image from a first storage unit and comparing the palm print image with the predefined palm print image; unlocking the intelligent entrance guard when the palm print image matches with the predefined palm print image and not unlocking the intelligent entrance guard when the palm print image does not match with the predefined palm print image.

First claim

What is claimed is:

1. An intelligent entrance guard unlocking system comprising:
a power unit configured to supply electric power;
a current transmitter electrically coupling the power unit to a transmit coil, the current transmitter configured to receive electric energy supplied by the power unit and transmit the electric energy in a way of wireless electromagnetic radiation via the transmit coil;
a first controller coupled to the power unit;
a first storage unit coupled to the first controller, and configured for storing a predefined palm print image;
a wireless receiver unit coupled to the first controller;
an unlocking unit coupled to the first controller; and
a powerless smart key configured for coupling with the wireless receiver unit, comprising:
a receiver coil;
a current receiver electrically coupled to the receiver coil and receiving the electric energy via the receiver coil such that the powerless smart key is powered by the received electric energy and the powerless smart key then starts to work;
a current convertor electrically coupling the current receiver with the second controller;
a first current-stabilizing unit electrically coupling the current receiver with the current convertor and configured to stabilize current of the received electric energy to prevent the current to exceed a predefined value suddenly;
a palm print capturing unit coupled to a second storage unit and configured to obtain a palm print image of the user and further store the palm print image in the second storage unit; and
a second controller coupled to a wireless transmit unit with the second storage unit and configured to control the wireless transmit unit to transmit a wireless signal containing the palm print image to the intelligent entrance guard; and
wherein the wireless receiver unit receives the wireless signal;
wherein the first controller is configured to compare the palm print image with the predefined palm print image; and
wherein the unlocking unit is configured to unlock when the palm print image matches with the predefined palm print image.

2. The intelligent entrance guard unlocking system of claim 1 , wherein the intelligent entrance guard unlocking system further comprises a light controlling unit and a light emitting unit, the light controlling unit electrically couples the first controller with the light emitting unit and is configured to control the light emitting unit to emit light with one color when the palm print image matches with the predefined palm print image and further control the light emitting unit to emit light with another color when the palm print image does not match with the predefined palm print image.

3. The intelligent entrance guard unlocking system of claim 1 , wherein the intelligent entrance guard unlocking system further comprises a second current-stabilizing unit electrically couple the power unit with the current transmitter and configured to stabilize current of the power unit to prevent the current to exceed a predefined value suddenly.

4. The intelligent entrance guard unlocking system of claim 1 , wherein the powerless smart key further comprises a current convertor electrically coupling the current receiver with the second controller and configured to convert alternating current of electric energy into direct current so as to power the powerless smart key.

5. The intelligent entrance guard unlocking system of claim 1 , wherein the first storage unit further stores a predefined identification code, and the second storage unit further stores an identification code of the powerless smart key, the wireless signal further contains the identification code, and the first controller is further configured to obtain the predefined identification code from the first storage unit and compare the identification code with the predefined identification code, and the unlocking unit is configured to unlock when the palm print image matches with the predefined palm print image and the identification code matches with the predefined identification code, and the unlocking unit is configured to not unlock when the palm print image does not match with the predefined palm print image or the identification code does not match with the predefined identification code.

6. The intelligent entrance guard unlocking system of claim 5 , wherein the intelligent entrance guard unlocking system further comprises a light controlling unit and a light emitting unit, the light controlling unit electrically couples the first controller with the light emitting unit, and is configured to control the light emitting unit to emit light with one color when the palm print image matches with the predefined palm print image and the identification code matches with the predefined identification code, and further control the light emitting unit to emit light with another color when the palm print image does not match with the predefined palm print image or the identification code does not match with the predefined identification code.

7. An intelligent entrance guard unlocking method comprising:
transmitting electric energy of a power unit of an intelligent entrance guard in a way of wireless electromagnetic radiation via a transmit coil;
receiving the electric energy via a receiver coil of a powerless smart key such that the powerless smart key is powered by the received electric energy and the powerless smart key then starts to work;
stabilizing current of the received electric energy to prevent the current to exceed a predefined value suddenly;
capturing a palm print image of an user and further storing the palm print image in a second storage unit of the powerless smart key;
controlling a wireless transmit unit of the powerless smart key to transmit a wireless signal containing the palm print image to the intelligent entrance guard;
obtaining a predefined palm print image from a first storage unit of the intelligent entrance guard and comparing the palm print image with the predefined palm print image;
unlocking the intelligent entrance guard when the palm print image matches with the predefined palm print image; and
not unlocking the intelligent entrance guard when the palm print image does not match with the predefined palm print image.

8. The intelligent entrance guard unlocking method of claim 7 , further comprising:
controlling a light emitting unit of the intelligent entrance guard to emit light with one color when the palm print image matches with the predefined palm print image; and
controlling the light emitting unit to emit light with another color when the palm print image does not match with the predefined palm print image.

9. The intelligent entrance guard unlocking method of claim 7 , further comprising:
stabilizing current of the power unit to prevent the current to exceed a predefined value suddenly.

10. The intelligent entrance guard unlocking method of claim 7 , further comprising:
converting alternating current of the electric energy into direct current so as to power the powerless smart key.

11. The intelligent entrance guard unlocking method of claim 7 , wherein the wireless signal further contains the identification code, the intelligent entrance guard unlocking method further comprises:
obtaining a predefined identification code from the first storage unit;
comparing the identification code with the predefined identification code;

unlocking the intelligent entrance guard when the palm print image matches with the predefined palm print image and the identification code matches with the predefined identification code; and
not unlocking the intelligent entrance guard when the palm print image does not match with the predefined palm print im
