Abstract

A non-contact control method and a non-contact control device are applied to a lock control device in a non-contact mode for manipulation. The non-contact control device includes a master control module and a slave control module. Both the master control module and the slave control module include a radio frequency identify (RFID) component and a Bluetooth component. In the master control module and the slave control module, the RFID component serves as first-layer authentication and unlocking and starts the Bluetooth component, and the Bluetooth component serves as second-layer authentication and unlocking and triggers a circuit control device. The master control module actively starts the slave control module and performs pairing and unlocking, so as to achieve a non-contact locking and control mode with low energy consumption and high security.

Claims

1. A non-contact control method, applicable to a master control module and a slave control module, wherein the master control module is electrically connected to a circuit control device, the master control module comprises a radio frequency identify (RFID) emitter, a first Bluetooth transceiver, and a switch, the slave control module comprises an RFID receiver and a second Bluetooth transceiver, the method comprising:

turning on the RFID emitter and the first Bluetooth transceiver, generating a low-frequency start signal by the RFID emitter, and sending a searching signal by the first Bluetooth transceiver;

turning on the second Bluetooth transceiver, when the RFID receiver receives the low-frequency start signal and identifies that the low-frequency start signal is correct;

returning encrypted data, when the second Bluetooth transceiver receives the searching signal; and

sending a trigger signal by the master control module to the circuit control device, when the first Bluetooth transceiver identifies that the encrypted data is correct.

2. The non-contact control method according to claim 1, further comprising:

receiving a key input signal through the slave control module;

transmitting a mode switching signal to the first Bluetooth transceiver; and

pairing the first Bluetooth transceiver with another Bluetooth transceiver, after receiving the mode switching signal.

3. The non-contact control method according to claim 2, wherein after the mode switching signal is transmitted to the first Bluetooth transceiver, the method further comprises:

transmitting a pairing parameter through the second Bluetooth transceiver of the slave control module; and

pairing the first Bluetooth transceiver with another Bluetooth transceiver, according to the pairing parameter.

4. The non-contact control method according to claim 3, wherein the pairing parameter comprises:

whether another Bluetooth transceiver requires inputting a password;

a quantity and a priority of another Bluetooth transceiver capable of being paired;

or

whether another Bluetooth transceiver is capable of reading vehicle information.

5. The non-contact control method according to claim 1, wherein after the master control module sends the trigger signal to the circuit control device, the method further comprises:

turning off the RFID emitter; and

turning off the RFID receiver.

6. The non-contact control method according to claim 1, wherein after the encrypted data is returned, the method further comprises:

judging whether authentication is completed, and if no, turning off the RFID emitter and the first Bluetooth transceiver, or turning off the RFID receiver and the second Bluetooth transceiver.

7. A non-contact control device, comprising a master control module and a slave control module, wherein the master control module is electrically connected to a circuit control device, the master control module comprises a radio frequency identify (RFID) emitter, a first Bluetooth transceiver, and a switch, the slave control module comprises an RFID receiver and a second Bluetooth transceiver, the switch turns on the RFID emitter and the first Bluetooth transceiver of the master control module, the RFID emitter sends a low-frequency start signal to the RFID receiver, so as to turn on the second Bluetooth transceiver, the first Bluetooth transceiver sends a searching signal to the second Bluetooth transceiver, and the second Bluetooth transceiver returns encrypted data to the first Bluetooth transceiver, such that the master control module sends a trigger signal to the circuit control device.

8. The non-contact control device according to claim 7, wherein the slave control module further comprises a key, when the key is pressed down, the slave control module controls the master control module to operate in a pairable mode, and the first Bluetooth transceiver of the master control module is capable of being paired with another Bluetooth transceiver.

9. The non-contact control device according to claim 8, wherein the slave control module is used to set a pairing parameter, and the first Bluetooth transceiver is paired according to the pairing parameter.

10. The non-contact control device according to claim 9, wherein the pairing parameter comprises:

whether another Bluetooth transceiver requires inputting a password;

a quantity and a priority of another Bluetooth transceiver capable of being paired;

or

whether another Bluetooth transceiver is capable of reading vehicle information.

11. The non-contact control device according to claim 7, wherein the RFID receiver identifies the low-frequency start signal, and when the RFID receiver identifies that the low-frequency start signal is correct, a microprocessor of the slave control module is switched from an OFF mode into an ON mode.

12. The non-contact control device according to claim 11, wherein the RFID receiver identifies the low-frequency start signal, and when the RFID receiver identifies that the low-frequency start signal is correct, the second Bluetooth transceiver is turned on.

13. The non-contact control device according to claim 7, wherein after the master control module sends the trigger signal to the circuit control device, the RFID emitter and the RFID receiver are turned off.
