[0024] Figure 1 A schematic diagram of an in-vehicle Internet of Things (IoT) system according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0025] An in-vehicle Internet of Things (IoT) system 10 includes: an external gateway 100 and a multi-channel image acquisition terminal 200.

[0026] The multi-channel image acquisition terminal 200 includes a multi-channel transmission module 210 and multiple image acquisition modules 220. The multi-channel transmission module 210 is pluggably connected to the external gateway 100 via the Ethernet interface 110 of the external gateway 100. The multi-channel transmission module 210 is connected to the multiple image acquisition modules 220 and is used to simultaneously transmit the image data uploaded by the multiple image acquisition modules 220 to the external gateway 100.

[0027] The external gateway 100 can acquire image data provided by multiple image acquisition modules 220 through the multi-channel transmission module 210. The acquired image data can be used for intelligent vehicle control, thereby expanding the functionality of the external gateway 100 to meet users' needs for vehicle intelligence.

[0028] The multi-channel transmission module 210 can be integrated with multiple image acquisition modules 220. One multi-channel transmission module 210 can drive and control multiple image acquisition modules 220. The separate design of the multi-channel image acquisition terminal 200 and the external gateway 100 makes it easy to place the external gateway 100 and the multi-channel image acquisition terminal 200 inside the vehicle.

[0029] The Ethernet interface 110 has a higher transmission rate than other types of interfaces, allowing the multi-channel transmission module 210 to be pluggably connected to the external gateway 100 via the Ethernet interface 110. This enables the simultaneous transmission of image data uploaded by multiple image acquisition modules 220 to the external gateway 100, even if the external gateway 100 and the multi-channel image acquisition terminal 200 are designed separately. The pluggable connection between the multi-channel transmission module 210 and the external gateway 100 also facilitates future replacement and upgrades of the multi-channel image acquisition terminal 200.

[0030] In one embodiment, such as Figure 2 As shown, the multi-channel image acquisition terminal 200 also includes an expansion interface 230, and the vehicle-mounted Internet of Things system 10 also includes an external image acquisition module 300. The expansion interface 230 is connected to the multi-channel transmission module 210, and the external image acquisition module 300 is pluggably connected to the expansion interface 230.

[0031] The multi-channel image acquisition terminal 200 may include multiple expansion interfaces 230 and multiple external image acquisition modules 300. The external image acquisition modules 300 can be placed away from the multi-channel transmission module 210 and the image acquisition module 220 as needed, supplementing the image acquisition module 220, acquiring images of areas that the image acquisition module 220 cannot capture, and generating corresponding image data. Shielded twisted-pair cables can be used to connect the expansion interfaces 230 and the external image acquisition modules 300 to reduce packet loss.

[0032] In some embodiments, the expansion interface 230 may include an automotive-grade BMW interface, specifically a data interface that meets the ISO 16750-3 vibration test standard for BMW models and can be used to transmit image data. It is understood that the specific type of the expansion interface 230 can be set according to actual needs, and this embodiment does not limit it.

[0033] In some embodiments, the multi-channel transmission module 210 can realize 6-channel image transmission.

[0034] The multi-channel image acquisition terminal 200 can be plugged into and connected to the external gateway 100, which also facilitates the replacement and upgrading of the multi-channel image acquisition terminal 200 in the future.

[0035] In some embodiments, the vehicle-mounted Internet of Things system 10 includes multiple multi-channel image acquisition terminals 200, and the external gateway 100 also has multiple Ethernet interfaces 110. The multiple multi-channel image acquisition terminals 200 can be connected one-to-one with the Ethernet interfaces 110. The specific number and installation location of the multi-channel image acquisition terminals 200 can be set according to actual needs.

[0036] In one embodiment, the multi-channel transmission module 210 specifically includes a system on chip (SOC) and a memory connected to the SOC. The SOC can be connected to each image acquisition module 220.

[0037] The SOC can acquire image data uploaded by each image acquisition module 220 and simultaneously transmit image data uploaded by multiple image acquisition modules 220 to the external gateway 100, realizing multi-channel image transmission. The memory can store the image data uploaded by the image acquisition modules 220.

[0038] Specifically, the multi-channel image acquisition terminal 200 and the Ethernet interface 110 of the external gateway 100 can be connected via an Ethernet twisted-pair cable. The Ethernet twisted-pair cable can also be used by the external gateway 100 to supply power to the multi-channel image acquisition terminal 200. In one embodiment, the multi-channel image acquisition terminal 200 uses a 12V power supply combined with an Ethernet twisted-pair cable for power supply, which provides stronger anti-interference capabilities compared to traditional USB power supply.

[0039] In one embodiment, such as Figure 3 As shown, the external gateway 100 includes a wireless communication module 120, which is connected to the Ethernet interface 110 and is used to wirelessly connect to the cloud platform.

[0040] The wireless communication module 120 can communicate with the cloud platform.

[0041] Specifically, the wireless communication module 120 includes modules such as a 3G module and a 4G module.

[0042] The wireless communication module 120 can be used to acquire image data received by the Ethernet interface 110 and upload the image data to the cloud platform.

[0043] In one embodiment, the external gateway 100 further includes a main control module 131, a universal serial bus hub 132, an OBD interface 133, and multiple data interfaces 134. The universal serial bus hub 132 is connected to both the wireless communication module 120 and the main control module 131. The main control module 131 is connected to both the OBD interface 133 and each of the data interfaces 134. The main control module 131 controls the signal transmission between the universal serial bus hub 132 and each of the data interfaces 134. The OBD interface 133 is used to connect to the vehicle's on-board diagnostics (OBD) system.

[0044] Each data interface 134 can be connected to different external devices, and the main control module 131 can communicate with each external device through each data interface 134. The main control module 131 can also control the data transmission between external devices and external networks. In addition to obtaining vehicle operation data provided by the vehicle's OBD system, the OBD interface 133 can also obtain the power required by the in-vehicle Internet of Things system 10 from the OBD system.

[0045] Specifically, the main control module 131 may include controllers such as chips and microcontrollers. The main control module 131 may be equipped with a Linux system call multi-protocol parsing module, and the OBD interface 133 may acquire vehicle operating data, such as engine data, diagnostic fault codes (DTCs), fuel level, etc.

[0046] In one embodiment, the data interface 134 includes at least one of an RS232 interface, an RS485 interface, a CAN interface, a J1708 interface, a J1850 interface, and a USB interface.

[0047] Understandably, the number and type of data interfaces 134 can be configured according to actual needs. The main control module 131 can exchange data with external devices using protocols such as J1939, J1708, and K-Line.

[0048] For example, in one embodiment, the external gateway 100 may include two RS232 interfaces and one RS485 interface.

[0049] The data interface 134 can also serve as an upgrade interface for the main control module 131 and the wireless communication module 120. Specifically, the upgrade interface can be a USB Type-A interface.

[0050] In some embodiments, data interface 134 may also include Ethernet interface 110.

[0051] For example, in one embodiment, the external gateway 100 may include two Ethernet interfaces 110, one of which is connected to the wireless communication module 120, and the other Ethernet interface 110 is connected to the main control module 131 as a data interface 134.

[0052] In one embodiment, the external gateway 100 further includes a global positioning system module 140, which is connected to the main control module 131.

[0053] The Global Positioning System module 140 can provide positioning information to the main control module 131.

[0054] In one embodiment, the external gateway 100 further includes an inertial navigation module 151 and a driving data storage module 152. The inertial navigation module 151 and the driving data storage module 152 are connected to the wireless communication module 120. The driving data storage module 152 is used to determine and store the driving status of the vehicle based on the inertial data provided by the inertial navigation module 151.

[0055] It should be noted that the inertial navigation module 151 can identify vehicle speed, steering angle, acceleration, braking and other driving information based on changes in inertia, and the driving data storage module 152 can record it so as to analyze the driver's driving behavior based on the vehicle's driving conditions.

[0056] By using the inertial navigation module 151 in conjunction with the global positioning system module 140, continuous positioning can be achieved in areas with poor positioning signals.

[0057] In one embodiment, the external gateway 100 further includes a WIFI communication module 161 and a Bluetooth communication module 162, both of which are connected to the Universal Serial Bus hub 132.

[0058] External devices can wirelessly connect to the vehicle gateway via the WIFI communication module 161 or the Bluetooth communication module 162.

[0059] In one embodiment, the in-vehicle IoT system 10 further includes an external power supply module, which is pluggably connected to the external gateway 100 and is used to provide operating voltage to the external gateway 100.

[0060] Specifically, the external power supply module may include a first power supply module and / or a second power supply module.

[0061] The first power module is used to connect to the vehicle's onboard power supply to generate the operating voltage based on the electrical energy provided by the onboard power supply. The second power module is used to generate the operating voltage through photoelectric conversion.

[0062] Specifically, the first power module may have a corresponding interface to connect to the vehicle's onboard power supply, for example, it may connect to the vehicle's 12V / 24V power supply to obtain sufficient power.

[0063] The second power module can include a solar panel, which can generate electricity through photoelectric conversion to obtain the operating voltage.

[0064] The operating voltage can be used to drive the in-vehicle IoT system 10.

[0065] In one embodiment, the in-vehicle IoT system 10 may further include an energy storage module. Specifically, the energy storage module may include a lithium battery.

[0066] The first power module, the second power module, and the energy storage module can all be plugged into and connected to the external gateway 100 via their respective interfaces.

[0067] Specifically, the first power module, the second power module, and the energy storage module can be plugged into the IP67 interface of the external gateway 100.

[0068] By employing multiple power supply methods, the stability of the vehicle-mounted Internet of Things system 10 can be ensured.

[0069] In one embodiment, at least one image acquisition module 220 includes a 4MP black light camera.

[0070] The 4MP black light camera supports H.265 encoding, Digital Still Camera (DSC) functionality, and Advanced Driving Assistance System (ADAS) functionality. Compared to other cameras, the 4MP black light camera is also relatively small in size, making it easy to install.

[0071] In some embodiments, both image acquisition modules 220 include a 4MP black light camera.

[0072] Figure 4 A schematic diagram of a vehicle according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and the details are as follows:

[0073] A vehicle 20 includes an in-vehicle Internet of Things (IoT) system 10 as described in any of the above embodiments.

[0074] In some embodiments, such as Figure 1 As shown, the vehicle-mounted Internet of Things system 10 includes: an external gateway 100 and a multi-channel image acquisition terminal 200.

[0075] The external gateway 100 is used to connect to an external network. The multi-channel transmission module is pluggably connected to the external gateway 100 via the Ethernet interface 110 of the external gateway 100. The multi-channel transmission module is used to connect to multiple image acquisition modules 220 and transmit the image data uploaded by the multiple image acquisition modules 220 to the external gateway 100.

[0076] A single multi-channel image acquisition terminal 200 can drive and control multiple image acquisition modules 220. The separate design of the multi-channel image acquisition terminal 200 and the external gateway 100 makes it easy to design the multi-channel image acquisition terminal 200 and the external gateway 100 separately according to actual needs, and also makes it easy to place the external gateway 100 and the multi-channel image acquisition terminal 200 reasonably inside the vehicle.

[0077] The Ethernet interface 110 has a higher transmission rate than other types of interfaces, enabling the simultaneous transmission of image data uploaded by multiple image acquisition modules 220 to the external gateway 100. Even if the external gateway 100 and the multi-channel image acquisition terminal 200 are designed separately, multi-channel image transmission can still be achieved.

[0078] The multi-channel image acquisition terminal 200 can be plugged into and connected to the external gateway 100, which also facilitates the replacement and upgrading of the multi-channel image acquisition terminal 200 in the future.
