The role of the switch in network access control is relatively limited, and it is mainly used to control the access and traffic distribution of a single access point. Among them, the role of the router in network access control is relatively important. It can control the access and traffic distribution between the wide area network and the local area network, and can also perform access control on users or access instructions.

Among them, the SE security module E14 can realize security protection in the communication field, has functions such as hardware authentication and anti-tampering, and can provide a higher level of protection for applications and keys with high security requirements. Among them, the HSM hardware security module E14 integrates various symmetric and asymmetric algorithms, has a very high security level, and can ensure that the keys and information data stored internally will not be illegally read and tampered with. It is a general term for a type of security chip; the core function of the HSM hardware security module E14 is centered around encryption and decryption, which can protect sensitive data and ensure that only authorized recipients or applications can get these data. At the same time, the hardware security module HSM will also provide a secure data decryption method to ensure the confidentiality of the message. Optionally, the security module E14 may also be connected to an alarm device, so that when a security problem occurs, the alarm device can be used to alert the user or display the details of the security problem.

[0035] In one embodiment, the Internet of Things module E12 can also be used to access the security module E14 to authenticate the authentication data in cooperation with the unlocking logic of the first authentication module to achieve unlocking control of the door. Therefore, when implementing the unlocking control, the Internet of Things module E12 can achieve the same or similar control logic as the controller E11 corresponding to the first channel.

[0036] In one embodiment, the Internet of Things module E12 is connected to the data receiving module E13 via a second path, wherein the second path includes a Universal Asynchronous Receiver / Transmitter (UART), which is an asynchronous receiver / transmitter that can convert data to be transmitted between serial communication and parallel communication. As a chip that converts parallel input signals into serial output signals, the Universal Asynchronous Receiver / Transmitter UART is usually integrated into a communication interface similar to a Bluetooth device.

[0037] In one embodiment, the data receiving module E1 may include a wireless communication device, a contact communication device (such as NFC). Optionally, the wireless communication device includes but is not limited to at least one of a Bluetooth device (such as a low-power Bluetooth device BLE) and an ultra-wideband communication device (such as a UWB (Ultra Wide Band) device).

[0038] In one embodiment, the data receiving module E13 can establish a connection with a digital key device (such as a mobile phone, a Bluetooth key, etc.), and connect to the Internet of Things module E12 through a second path, so that the Internet of Things module E12 can complete the authentication and control the unlocking module E2 to perform unlocking control. Optionally, the unlocking module E2 can perform unlocking control on the vehicle doors, the trunk, etc.

[0039] The controller E11 is connected to the Internet of Things module E12, and is connected to the data receiving module E13 through a first path, and has a second authentication module (not shown in the figure).

[0040] In one embodiment, the controller E11 is connected to the data receiving module E13 through a first path, so that the data receiving module E13 establishes a connection with the digital key device, and can transmit the authentication data corresponding to the digital key device to the controller E11 through the first path, so that the controller E11 can transmit the control command to the unlocking module E2 through the Internet of Things module E12 to realize the unlocking control after completing the authentication. The digital key device includes a smart terminal (such as a mobile phone, a smart watch, a smart bracelet, etc.), an independent Bluetooth key, and other devices that can transmit unlocking authentication data. The independent Bluetooth key can be a device that mainly has the function of a Bluetooth key.

[0041] In one embodiment, the controller E11 is also connected to a security module E14 for accessing the security module E14 to cooperate with the unlocking logic of the second authentication module to authenticate the acquired authentication data, so as to achieve matching authentication of the authentication data transmitted by the data receiving module E13 with the authentication data in the security module E14.

[0042] In one embodiment, the controller E11 is connected to the security module E14 and the Internet of Things module E12 can be connected via an SPI interface; the first path connecting the controller E11 and the data receiving module E13 includes a universal asynchronous receiver-transmitter UART.

[0043] In one embodiment, the controller E11 may be a microcontroller unit (MCU), which may appropriately reduce the frequency and specifications of the central processing unit, and integrate peripheral interfaces such as memory, counter, universal serial bus (USB), and analog to digital (A / D) conversion on a single chip to form a chip-level computer to perform different combination controls for different application scenarios.

[0044] In one embodiment, the controller E11 can send operating information to the Internet of Things module E12 periodically or in real time, so that when the controller E11 fails (for example, the operating information includes a fault code or response delay information, or the Internet of Things module E12 does not receive the operating information sent by the controller E11 within a preset time), the Internet of Things module E12 can take over the controller E11 and receive the authentication data transmitted by the data receiving module E13 through the second channel to realize unlocking control of the unlocking module E2.

[0045] In one embodiment, the information processing device E1 may be a vehicle network information processing device TCAM (Telematics Connectivity Antenna Module). The vehicle network information processing device TCAM is a central node for the vehicle communication system to communicate with the outside world.

[0046] The door lock control system provided by the first embodiment of the present application includes: an information processing device E1 and an unlocking module E2, wherein the information processing device E1 includes an Internet of Things module E12, a data receiving module E13, a first path, a second path and a controller E11. The Internet of Things module E12 is connected to the unlocking module E2, and is connected to the data receiving module E13 through the second path, and has a first authentication module. The controller E11 is connected to the Internet of Things module E12, and is connected to the data receiving module E13 through the first path, and has a second authentication module. In this way, the present application can configure authentication modules for the Internet of Things module E12 and the controller E11 respectively so that both the Internet of Things module and the controller have authentication functions, so that the Internet of Things module can be directly connected to the data receiving module E13, and then when the controller E11 fails, it can switch to the Internet of Things module to realize data authentication and backup unlocking control of the unlocking module E2. In addition, the present application can only add a path between the data receiving module E13 and the Internet of Things module on the basis of some current technologies to realize backup unlocking control, with less hardware changes and low improvement costs. Therefore, this embodiment can ensure that the unlocking control can still be completed when the controller E11 for implementing the digital key unlocking control fails, thereby improving the user experience. In addition, this embodiment can also ensure that the unlocking control can still be completed when the IoT module E12 fails in other solutions that prioritize the implementation of the digital key unlocking control, thereby improving the user experience.

[0047] Based on the technical concept of the above technical solution, the following example is an application scenario of a door lock control system for reference:

[0048] See also Figure 2 , the information processing device E1 is a vehicle network information processing device TCAM, the data receiving module E13 is a low-power Bluetooth device BLE, the controller E11 is a microcontroller unit MCU, the Internet of Things module E12 is a network access device NAD, and has a software development kit SDK, the security module E14 is a SE security module, the first channel UART1, and the second channel UART2;

[0049] The normal low-power Bluetooth technology unlocking process is as follows:

[0050] 1) In the vehicle sleep mode, the low-power Bluetooth device BLE is in low-power polling, and broadcast polling is performed every 40-100ms;

[0051] 2) When the low-power Bluetooth device BLE detects the digital key device (such as a mobile phone with Bluetooth function), it connects and pairs;

[0052] 3) After the pairing is successful, the low-power Bluetooth device BLE wakes up the microcontroller unit MCU inside the vehicle network information processing device TCAM through the first channel UART1, so that the vehicle network information processing device TCAM is in working state;

[0053] 4) The low-power Bluetooth device BLE transmits authentication data with the digital key device (such as a mobile phone with Bluetooth function);

[0054] 5) The low-power Bluetooth device BLE transmits the authentication data to the microcontroller unit MCU through the first channel UART1;

[0055] 6) The microcontroller unit MCU performs user identity authentication processing;

[0056] 7) The entire vehicle network information processing device TCAM interacts with the low-power Bluetooth device BLE;

[0057] 8) The microcontroller unit MCU of the vehicle network information processing device TCAM completes the authentication and sends the unlocking instruction to the unlocking module;

[0058] 9) The unlocking module authenticates the data and issues an unlocking instruction;

[0059] 10) Unlock and feedback the current instruction execution status;

[0060] 11) The vehicle network information processing device TCAM feeds back to the digital key device (such as a mobile phone with Bluetooth function);

[0061] 12) Complete the unlocking process once.

[0062] When the microcontroller unit MCU is abnormal, the low-power Bluetooth technology unlocking process is as follows:

[0063] Trigger condition: When the microcontroller unit MCU fails to work properly, it cannot process the data transmitted by the low-power Bluetooth device BLE through the second channel UART2;

[0064] 1) When the low-power Bluetooth device BLE sends data to the microcontroller unit MCU, the microcontroller unit MCU does not respond;

[0065] 2) The low-power Bluetooth device BLE can switch the data receiving channel to change the first channel UART1 to the second channel UART2, or the network access device NAD opens the second channel UART2 to receive the authentication data transmitted by the low-power Bluetooth device BLE; wherein, the network access device NAD pre-backs up the unlocking program in the microcontroller unit MCU through the software development kit SDK.

[0066] 3) When the low-power Bluetooth device BLE is connected through the second channel UART2, the unlocking program of the software development kit SDK in the network access device NAD is triggered, and the corresponding unlocking control is executed;

[0067] 4) After the network access device NAD authenticates the authentication data transmitted by the low-power Bluetooth device BLE, it transmits the control command to the unlocking module;

[0068] 5) The unlocking module receives the control instruction and completes the unlocking action.

[0069] Therefore, the door lock control system of the example in this embodiment can ensure that the unlocking control can still be completed when the controller for implementing the digital key unlocking control fails, thereby improving the user experience, and has the advantages of easy implementation and low cost.

The second wireless communication device E132 establishes a connection with the digital key device, and is connected to the Internet of Things module E12 through a second path, for transmitting the authentication data in the digital key device to the Internet of Things module E12. Therefore, this embodiment can ensure that the unlocking control can still be completed when at least one of the first wireless communication device E131 and the controller E11 connected by the first path fails, thereby improving the user experience.

[0073] In one embodiment, the wireless communication device includes but is not limited to at least one of a Bluetooth device (eg, a low-power Bluetooth device BLE) and an ultra-wideband communication device (eg, a UWB (Ultra Wide Band) device).

[0074] In one embodiment, the controller E11 can send operating information to the Internet of Things module E12 periodically or in real time, so that when the controller E11 fails (for example, the operating information includes a fault code or response delay information, or the Internet of Things module E12 does not receive the operating information sent by the controller E11 within a preset time), the Internet of Things module E12 can take over the controller E11 and receive the authentication data transmitted by the first wireless communication device E131 through the second path to realize unlocking control of the unlocking module E2.

[0075] In other embodiments, the data receiving module further includes a switching device for switching on one of the first wireless communication device E131 and the second wireless communication device E132. The switching device can switch on the second wireless communication device E132 when the first wireless communication device E131 fails.

In this way, the present application can respectively configure authentication modules for the IoT module and the controller E11 so that both the IoT module and the controller have authentication functions, so that the IoT module can connect to the second wireless communication device E132, so that when the controller E11 fails, it can switch to the IoT module E12 to realize data authentication and backup unlocking control of the unlocking module E2. Therefore, this embodiment can ensure that the unlocking control can still be completed when the controller E11 and / or the first wireless communication device E131 that realizes the digital key unlocking control fails, thereby improving the user experience.
