Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 and FIG. 2, the first embodiment of the electronic control lock system with NFC identification function is suitable for being installed between a power supply system 8 and an electronic device 9, and can be unlocked and activated by the power supply system 8 The electric power triggers the electronic device 9, and the electronic control lock system having the NFC identification function includes a key device 1, and a lock device 2.

The key device 1 includes a key 11, and an NFC wafer 12 mounted to the key 11 and storing a password. The key 11 is made of a hard material such as metal or plastic, and is a specific structure that can be matched with the lock device 2, such as a special tooth scale and groove, so that the key 11 can only be used to unlock the key. Lock device 2. The NFC wafer 12 is a chip designed using NFC (Near Field Communication) technology to enable wireless communication with compatible devices for identification and data transmission in a short distance. The NFC wafer 12 of the present embodiment can be passively triggered by the lock device 2 and wirelessly powered by the lock device 2, and data transfer is performed with the lock device 2 using load modulation technology, but in practice, the NFC wafer 12 is implemented. It is also possible to actively carry out data transmission with the lock device 2 in conjunction with its own power source, which is not limited to this embodiment.

The lock device 2 includes a lock 3 electrically connected to the electronic device 9, and a lock controller 4 mounted between the lock 3 and the power supply system 8 and capable of transmitting a portion of the power supply system 8 to the lock 3.

The lock 3 includes a lock head 31. The lock head 31 is embedded and exposed, and the key 11 matched with the lock 11 can be electrically driven to trigger the electronic device 9. For example, the electric door lock of the steam locomotive can be ignited to start the steam locomotive by a rotary method. Therefore, the technical content will not be detailed here.

The lock 3 is controllable by the lock controller 4 to vary between a power down state and an energized state. When the lock 3 is in the energized state, the lock controller 4 can transmit a portion of the power supply system 8 to the lock 3, so that the lock 3 can use the power of the power supply system 8 when the lock 31 is rotated. The electronic device 9 is driven. Conversely, when the lock 3 is in the power-off state, the lock controller 4 stops transmitting the power of the power supply system 8 to the lock 3, so even if the lock 31 is rotated, the lock 3 cannot drive the electronic device. 9. It should be noted that if the key 11 inserted at this time is the key 11 that does not match the lock 31, the lock 31 cannot be rotated, and the electronic device 9 cannot be driven naturally.

The lock controller 4 has a switch unit 21, an NFC sensing unit 22, a detecting unit 23, a prompting unit 24, a remote return unit 25, and a processing unit 26.

The switch unit 21 can be driven open to deliver a portion of the power supply system 8 to the lock 3. If the switch unit 21 outputs the power of the power supply system 8 to the lock 3, the lock 3 is brought into the energized state. If the switch unit 21 does not output the power of the power supply system 8 to the lock 3, the lock 3 will enter the power-off state. Therefore, the switch unit 21 can control the lock 3 to switch between the power-on state and the power-off state.

The NFC sensing unit 22 can actively generate a radio frequency domain 221 by using NFC (Near Field Communication) technology to sense the NFC wafer 12, so the NFC sensing unit 22 must be mounted near the lock 31 so that the key 11 is inserted into the lock. At the head 31, the NFC wafer 12 of the key device 1 can be located within the RF domain 221. The NFC sensing unit 22 uses the shot The frequency domain 221 can wirelessly supply power to the NFC chip 12, and is synchronously coupled to the NFC chip 12 for wireless data transmission, and inductively reads and changes the password of the NFC wafer 12. The NFC sensing unit 22 can be configured to perform only one-to-one synchronization connection to improve the confidentiality and security of data transmission, but the implementation is not limited thereto.

The detecting unit 23 can detect whether the lock 31 is rotated by the key 11 by using optical, touch pressure and electromagnetic methods. Since the detection mode is of various types and is a prior art, it is not the focus of the invention, so it is not here. More details.

The prompting unit 24 can be driven by the processing unit 26 to issue a prompt message. In the embodiment, the prompting unit 24 is embedded in the lock 3 and is an LED capable of emitting different colors of light, and can be driven to be emitted. The prompt light representing the prompt message, but in practice, the prompting unit 24 can also be used with an electronic component such as a buzzer that can emit sound, or an electronic component that can emit a voice.

The remote reward unit 25 can send an alert message to an electronic device 7 of the legal owner of the electronic device 9 by using a network or wireless communication, and the electronic device 7 can be a computer, a mobile phone, a tablet computer, or the like. Electronic device for wireless communication or network 7.

The processing unit 26 is connected to the NFC sensing unit 22, the detecting unit 23, the prompting unit 24 and the remote reporting unit 25, and has a storage module 261 storing a verification code and a comparison module 262. A password generation module 263 and a control module 265.

The alignment module 262 can compare the density of the NFC wafer 12 Whether the code matches the verification code. In this embodiment, the comparison module 262 directly compares the password with the verification code, but in fact, the password may have been previously encrypted, so the comparison module 262 is compared before The password needs to be decrypted before it can be compared with the verification code, so that confidentiality and security can be increased.

The password generation module 263 can be driven to generate a new set of passwords and verification codes in random. In this embodiment, the new password is the same as the new verification code, but in practice, the new password can be pre-encrypted by the password generation module 263 according to the calculation method corresponding to the comparison module 262, and After decryption by the comparison module 262, it can be the same as the new verification code.

The control module 265 can control the prompting unit 24, and when the comparison module 262 is matched, the prompting unit 24 is controlled to send a prompt message indicating that the matching is matched; when the comparison does not match, the prompting unit is controlled. 24 sends a prompt message that does not match the comparison, such as emitting a green light to indicate a match, and a red light to indicate a mismatch.

The control module 265 can control the switch unit 21, and when the comparison module 262 is matched, the switch unit 21 is controlled to supply the power of the power supply system 8 to the lock 3, so that the lock 3 enters a power-on state; When the pair does not match, the switch unit 21 is controlled to stop the power supplied to the power supply system 8 to the lock 3, and the lock 3 is brought into a power-off state.

The control module 265 can control the password generation module 263. When the comparison module 262 is matched and the detection unit 23 detects that the lock 31 is rotated by the key 11, the password generation module is controlled. 263 generates a new verification code and the password. The control module 265 can overwrite the new verification code The verification module stores the verification code and drives the NFC sensing unit 22 to replace the password of the NFC chip 12 with the new password.

The control module 265 can control the remote reward unit 25, and when the comparison module 262 does not match, control the remote reward unit 25 to send the alarm message to the electronic owner of the electronic device 9 Device 7.

When the electronic control lock system having the NFC identification function of the present invention is used, the key 11 needs to be inserted into the lock 31, and the NFC sensing unit 22 senses the NFC wafer 12 of the key device 1 to make the NFC sensing unit 22 The NFC chip 12 is energized and searched for each other, and the password stored in the NFC chip 12 is read, and then the comparison module 262 can compare the password of the NFC chip 12 with the storage module 261. The verification code matches.

When the comparison is consistent, the control module 265 can drive the prompting unit 24 to issue a matching prompt message to prompt the user to match the result, and drive the switch unit 21 to be turned on, so that the lock 3 enters the power-on. In this state, the user can use the key 11 to rotate the lock 31 to drive the electronic device 9. When the detecting unit 23 detects that the lock 31 is rotated, the control module 265 drives the password generating module 263 to automatically generate the new password and the new verification code, and the new password and The new verification code overwrites the password of the NFC wafer 12 and the verification code of the storage module 261.

When the comparison does not match, the control module 265 drives the prompting unit 24 to issue a prompt message that does not match the comparison, to prompt the user to compare. The result is inconsistent, and drives the switch unit 21 to stop transmitting power of the power supply system 8 to the lock 3, and causes the lock 3 to enter the power-off state. At this time, even if the user rotates the lock 31 by using the key 11, It is also impossible to drive the electronic device 9. At the same time, the remote reward unit 25 automatically sends the alarm message to the electronic device 7 of the legal owner of the electronic device 9, thereby reminding the legal owner of the electronic device 9, that someone attempts to use the key device with the incorrect password. Unlocking, for example, attempting to steal a car, in order to facilitate immediate access to the scene or alarm, etc., to avoid property damage.

In summary, the present invention has an NFC recognition function electronic control lock system, which can automatically change the verification code and the password of the key device 1 when the user activates the electronic device 9 by using the correct key device 1. It can be changed at any time to greatly increase the difficulty of stealing the electronic device 9; and when the user attempts to activate the electronic device 9 by using the incorrect key device 1, an automatic remote return is performed to facilitate instant notification processing. Therefore, the anti-theft property and safety can be effectively improved, and the object of the present invention can be achieved.

Referring to FIG. 2 and FIG. 3, the system architecture of the second embodiment of the electronic control lock system with NFC identification function of the present invention is substantially the same as the first embodiment, except that the key device 1 omits the key 11 (see 1), and the lock 3 replaces the lock head 31 with a boot button 32 that is embedded and pressed for pressing, and an insertion slot 33 that is recessed on the surface and is insertable by the key device 1 (see FIG. 1).

After the start button 32 is pressed, the electronic device 9 can be electrically triggered. For example, the electric door start lock of the steam locomotive can be activated by pressing. Because of the conventional technology, the locomotive does not detail the technical content here.

When the lock 3 is in the energized state, the lock controller 4 can transmit a portion of the power supply system 8 to the lock 3, so that the lock 3 can use the power of the power supply system 8 when the start button 32 is pressed. The electronic device 9 is driven. Conversely, when the lock 3 is in the power-off state, the lock controller 4 stops transmitting the power of the power supply system 8 to the lock 3, so even if the start button 32 is pressed, the lock 3 cannot drive the electronic device. 9.

The detecting unit 23 can detect whether the starting button 32 is pressed by using optical, touch, and electromagnetic methods. Since the detecting method is of various types and is a prior art, it is not the focus of the invention, and therefore will not be described in detail herein. .

In use, the key device 1 needs to be inserted into the insertion slot 33, and the NFC sensing unit 22 senses the NFC wafer 12 of the key device 1 to enable the NFC sensing unit 22 and the NFC wafer 12 to be energized. The pairing is searched for each other, and the password stored in the NFC chip 12 is read. Then, the comparison module 262 can match whether the password of the NFC wafer 12 matches the verification code in the storage module 261.

When the comparison is consistent, the control module 265 can drive the prompting unit 24 to issue a matching prompt message to prompt the user to match the result, and drive the switch unit 21 to be turned on, so that the lock 3 enters the power-on. In this state, the user can press the start button 32 to drive the electronic device 9. When the detecting unit 23 detects that the start button 32 is pressed, the control module 265 drives the password generating module 263 to automatically generate the new password and the new verification code, and the new password and New verification code overlay Write the password of the NFC wafer 12 and the verification code of the storage module 261.

When the comparison does not match, the control module 265 drives the prompting unit 24 to issue a prompt message that does not match the comparison, to prompt the user to not match the result, and drives the switch unit 21 to stop transmitting the power supply system 8. Power is supplied to the lock 3, and the lock 3 is brought into the power-off state. At this time, even if the user presses the start button 32, the electronic device 9 cannot be driven. At the same time, the remote reward unit 25 automatically sends the alarm message to the electronic device 7 of the legal owner of the electronic device 9, thereby reminding the legal owner of the electronic device 9, that someone attempts to use the key device with the incorrect password. Unlocking, for example, attempting to steal a car, in order to facilitate immediate access to the scene or alarm, etc., to avoid property damage.
