[0030] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0031] Exemplary device wireless network self-matching method

[0032] Figure 1 Fig. 1 shows a schematic diagram of method steps of a device wireless network self-matching method according to an embodiment of the present application. The present application provides a device wireless network self-matching method. In an embodiment, the device is a car, an engineering vehicle, or an engineering machine, etc., such as Figure 1 Fig. 1 shows a schematic diagram of method steps of a device wireless network self-matching method according to an embodiment of the present application. The present application provides a device wireless network self-matching method. In an embodiment, the device is a car, an engineering vehicle, or an engineering machine, etc., such as

[0033] determining whether the device is powered on, and if so, performing step 110, the Internet of Vehicles system sends network configuration data to one or more controllers through a wired connection.

[0034] In this step, after the device is powered on, the Internet of Vehicles system (TBOX) sends network configuration data in a wired form. The wired form does not need to rely on wireless network connection, thereby ensuring the timeliness and reliability of data transmission. Specifically, the network configuration data includes the hotspot name of the Internet of Vehicles system, the hotspot key of the Internet of Vehicles system, the IP address of the Internet of Vehicles system, the IPv4 subnet prefix length of the Internet of Vehicles system, and the gateway IP address of the Internet of Vehicles system. The wired connection can adopt a CAN bus or other wired connection mode. The hotspot name is consistent with the factory number of the Internet of Vehicles system, the data length is 12 bytes, the data type is ASCII code, and multiple frames need to be transmitted; the hotspot key adopts an 8-byte random code composed of letters / numbers / characters, the data length is 8 bytes, the data type is ASCII code, and multiple frames need to be transmitted; the IP address of the Internet of Vehicles system adopts a 4-byte 16 hexadecimal number transmission; the IPv4 subnet prefix length of the Internet of Vehicles system adopts a 1-byte 16 hexadecimal number transmission; and the gateway IP address of the Internet of Vehicles system adopts a 4-byte 16 hexadecimal number transmission. The controller is a device inside the device that needs to be upgraded by over-the-air download.

[0035] In step 120, the controller acquires network configuration data, and the controller performs wireless network connection with the Internet of Vehicles system according to the network configuration data.

[0036] In this step, the controller attempts to establish a wireless network connection with the Internet of Vehicles system based on the network configuration data. Specifically, the controller attempts to perform wireless network configuration and IP information configuration according to the hotspot name, the hotspot key, the IP address, the IPv4 subnet prefix length, and the gateway IP address of the Internet of Vehicles system.

[0037] In step 130, the Internet of Vehicles system sends connection success information to the controller that successfully establishes a wireless network connection and sends connection failure information to the controller that fails to establish a wireless network connection through wired connection.

[0038] In this step, the Internet of Vehicles system determines which controllers successfully establish a wireless network connection with the Internet of Vehicles system and which controllers fail to establish a wireless network connection with the Internet of Vehicles system. After the determination is completed, the Internet of Vehicles system broadcasts connection success information to the controllers that successfully establish a wireless network connection and broadcasts connection failure information to the controllers that fail to establish a wireless network connection.

[0039] The controller determines whether the connection success information or the connection failure information is received. If the controller receives the connection success information, the controller performs step 140, and sends an upgrade request to the Internet of Vehicles system.

[0040] In this step, if the connection is successful, it means that the controller successfully establishes a wireless network connection with the Internet of Vehicles system. When the controller needs to upgrade software information, the controller sends an upgrade request, and the Internet of Vehicles system sends matching software information to the controller for upgrading.

[0041] If the controller receives the connection failure information, step 150 is performed, and the controller sends a reconnection request to the vehicle networking system.

[0042] In this step, the connection failure indicates that the controller has not successfully established a wireless network connection with the vehicle networking system according to the network configuration data. At this time, the controller needs to reattempt to establish a wireless network connection with the vehicle networking system and sends a reconnection request to request the vehicle networking system to send network configuration data again. The reconnection request of this step can be sent through a wired connection to ensure the timeliness and reliability of data transmission.

[0043] The vehicle networking system determines whether the reconnection request is obtained. If the reconnection request is obtained, step 160 is performed, and the network configuration data is re-sent to the controller corresponding to the reconnection request through a wired connection to enable the controller to reestablish a wireless network connection with the vehicle networking system.

[0044] In this step, the vehicle networking system re-sends the network configuration data to the controller that needs to be reconnected through a wired connection. The controller reattempts to establish a wireless network connection with the vehicle networking system according to the network configuration data, thereby being able to perform the upgrade task.

[0045] In use, the embodiment can enable the vehicle networking system to send network configuration data for a wireless network connection to each controller through a wired connection when the device is powered on. The wired transmission does not need to rely on a wireless network connection, thereby ensuring the timeliness and reliability of data transmission. The controller attempts to establish a wireless network connection with the vehicle networking system according to the network configuration data. If the connection is successful, the controller can request the upgrade software information. If the connection fails, the controller requests the vehicle networking system to re-sent the network configuration data. The vehicle networking system receives the reconnection request and re-sends the network configuration data to the corresponding controller through a wired connection. The embodiment can enable the vehicle networking system to establish a wireless network connection with the controller when the device is powered on. When the connection fails, the vehicle networking system reattempts to establish a wireless network connection again, thereby ensuring that the controller that needs to be upgraded can establish a wireless network connection with the vehicle networking system to perform software upgrade.

[0046] Figure 2 FIG. 1 shows a method step schematic diagram of a device wireless network self-matching method provided by another embodiment of the application. In an embodiment, as shown in FIG. 1, if the device is powered on, step 110 includes: Figure 2

[0047] Step 111: The vehicle networking system sends a vehicle networking system hotspot name, a vehicle networking system hotspot key, an IP address of the vehicle networking system, an IPv4 subnet prefix length of the vehicle networking system, and a gateway IP address of the vehicle networking system to the controller through a wired connection.

[0048] Figure 3 ​Fig. 1 shows a flowchart of a method for self-matching of a wireless network of a device according to an embodiment of the present application. In an embodiment, as shown in Fig. 1, the method comprises the following steps: Figure 3 Step 120 comprises:

[0049] Step 121, the controller configures the wireless network according to the network configuration data.

[0050] Step 122, the controller sends a response message to the vehicle networking system through the wired connection.

[0051] In use, the controller first attempts to configure the wireless network and IP information according to the hotspot name, the hotspot key, the IP address, the IPv4 subnet prefix length, and the gateway IP address of the vehicle networking system. After the attempt, the controller sends a response message to the vehicle networking system to indicate that the controller has attempted to connect to the wireless network. The response message includes the IP address of the controller. The vehicle networking system marks the controllers that have attempted to connect to the wireless network according to the response message, so as to test the network connection of the marked controllers later.

[0052] Figure 4 Fig. 2 shows a flowchart of a method for self-matching of a wireless network of a device according to another embodiment of the present application. In an embodiment, as shown in Fig. 2, the method comprises the following steps: Figure 4 Step 122 comprises:

[0053] The controller determines whether the wireless network configuration has been performed. If the wireless network configuration has been performed, the controller generates feedback data for the network communication protocol in step 1221.

[0054] In this step, after the controller performs the wireless network connection according to the network configuration data, the controller generates a response to the network communication protocol, i.e., generates feedback data to indicate that the controller has attempted to connect to the wireless network.

[0055] Step 1222, the controller sends the feedback data to the vehicle networking system through the wired connection.

[0056] In this step, the controller sends the feedback data to the vehicle networking system, so that the vehicle networking system knows which controllers have attempted to connect to the wireless network.

[0057] Step 1223, the controller sends the IP address of the controller to the vehicle networking system through the wired connection.

[0058] In this step, the controller sends the IP address of the controller to the vehicle networking system, so that the vehicle networking system can distinguish different controllers according to the IP addresses.

[0059] In use, if the controller performs wireless network configuration, the controller triggers the generation of feedback data and sends the feedback data to the vehicle networking system, i.e., the response message is sent to the vehicle networking system in the form of feedback data. At the same time, the IP address of the controller itself is also sent, i.e., the response message contains the IP address of the controller itself. Then, the vehicle networking system can identify which controllers send the response message according to the IP address, and distinguish different controllers through the IP address.

[0060] Figure 5 As shown in the method steps schematic diagram of the device wireless network self-matching method provided by another embodiment of the application, after the controller sends the response message to the vehicle networking system through the wired connection, the method further includes: Figure 5

[0061] Step 170, the vehicle networking system judges whether the controller that has sent the response message is connected successfully or failed according to the network connection test method.

[0062] In use, the vehicle networking system tests the controllers that have attempted wireless network connection to know whether these controllers are connected successfully, so as to send the connection success information to the controllers connected successfully and send the connection failure information to the controllers connected failed. Specifically, the network connection test method can use common methods, for example, the vehicle networking system pings the IP address of the controller. If the ping is successful, it means that the controller has successfully established the wireless network connection. If the ping fails, it means that the establishment fails.

[0063] Figure 6 As shown in the method steps schematic diagram of the device wireless network self-matching method provided by another embodiment of the application, after the controller sends the response message to the vehicle networking system through the wired connection, the method further includes: Figure 6

[0064] Step 180, the vehicle networking system performs a judgment step according to the amount of sent network configuration data and according to the amount of received response messages, i.e., detects whether there is a controller that has not sent the response message.

[0065] If there is a controller that has not sent the response message, step 190 is performed, i.e., the vehicle networking system marks the controller that has not sent the response message as a controller connected failed.

[0066] ​​In use, if some controllers do not send the response message, it indicates that these controllers can not have received the network configuration data, and these controllers can not have performed the wireless network connection. If the sending amount of the network configuration data is greater than the amount of the received response message, it indicates that some controllers do not send the response message. Each response message contains the IP address of the corresponding controller, and the vehicle networking system can distinguish the controller corresponding to the response message through the IP address in the response message, so as to know which controllers do not send the response message. The vehicle networking system marks these controllers which do not send the response message as the connection-failed controllers.

[0067] Figure 7 Fig. 6 shows a method step schematic diagram of a device wireless network self-matching method provided by another embodiment of the application. In an embodiment, as shown in Fig. 6, step 130 includes: Figure 7

[0068] Step 131: The vehicle networking system sends the connection-success information to the connection-successful controllers through the wired connection according to a preset period.

[0069] Step 132: The vehicle networking system sends the connection-failure information to the connection-failed controllers through the wired connection according to a preset period.

[0070] In use, the connection-success information and the connection-failure information can be periodically sent to avoid too large data amount and too much energy consumption caused by frequent sending. Specifically, the sending period can be 3s, 10s or 15s.

[0071] Figure 8 Fig. 6 shows a method step schematic diagram of a device wireless network self-matching method provided by another embodiment of the application. In an embodiment, as shown in Fig. 6, step 130 includes: Figure 8

[0072] In a single power-on of the device, the judgment step is performed: whether the number of times that the controller sends the reconnection request to the vehicle networking system exceeds a preset upper limit. If yes, step 210 is performed: the controller no longer sends the reconnection request.

[0073] ​​In use, if the controller sends the reconnection request too many times, it indicates that the controller may have a connection failure and cannot establish a wireless network connection with the Internet of Vehicles system. At this time, the controller is controlled not to send the reconnection request, so as to avoid repeatedly requesting the Internet of Vehicles system to send network configuration data, and to avoid resource waste caused by meaningless data transmission. Subsequently, after the device is repaired, the wireless network connection is tried again. When the device is powered on next time, the controller can send the reconnection request again until the preset upper limit of the number of times is exceeded or the connection is successful. Specifically, the preset upper limit of the number of times can be set to 3, 5 or 10 times, etc.

[0074] Figure 9 Fig. 1 shows a schematic diagram of method steps of a device wireless network self-matching method provided by another embodiment of the application. In an embodiment, as shown in Fig. 1, the method further includes: Figure 9

[0075] Step 220: The controller sends the controller network information to the Internet of Vehicles system through the wired connection when the device is powered on each time.

[0076] Step 230: The Internet of Vehicles system sends the Internet of Vehicles system network information to the controller through the wired connection when the device is powered on each time.

[0077] The embodiment can enable the Internet of Vehicles system to update the network information of each controller, and the controller can also update the network information of the Internet of Vehicles system. Subsequently, the Internet of Vehicles system and the controller can use the latest network information to interact with, connect with and upgrade each other.

[0078] In the application, the communication between the Internet of Vehicles system and the controller can adopt a message format. The message format mainly includes two main parts:

[0079] One part is data for describing message format information, including data information identifier and data packet serial number. The data information identifier is used to describe the data content contained in the CAN bus data field. The data packet serial number is used to identify the order of multiple messages when the data information length exceeds the length of a single message that can be sent.

[0080] The other part is the actual data of the message.

[0081] The description of the message format information is as shown in Table 1:

[0082]

[0083] Table 1

[0084] ​The message data required for the vehicle-to-everything (V2X) system and controller to complete the handshake is shown in Table 1, containing seven categories of message data: V2X hotspot name, V2X hotspot key, V2X IP address and IPv4 subnet prefix length, V2X gateway IP address, controller connection status, controller reconnection request, and controller response message. Descriptions of the seven categories of message data are as follows:

Referring to Table 2, the general flowchart of this application is as follows: Figure 10 As shown, after the device is powered on, the vehicle-to-everything (V2X) system sends messages 1, 2, 3, and 4 to the controller. The controller configures the wireless network based on messages 1 and 2, and configures the IP information based on messages 3 and 4. After configuring the wireless network and IP information, the controller sends message 7 to the V2X system. Upon receiving message 7, the V2X system sends message 5 to the controller. Upon receiving message 5, the controller sends message 6 to the V2X system to request reconnection. Upon receiving message 6, the V2X system again sends messages 1, 2, 3, and 4 to the controller. During a single power-on, the device is configured to send a maximum of 3 messages of message 6.
