[0031] Figure 2 This is a schematic diagram of a vehicle full-volume raw data acquisition system provided for an embodiment of the present utility model.

[0032] The system includes a bracket 1, a vehicle-mounted data acquisition device 2, a power supply module 21, a first data mirroring submodule 221, a second data mirroring submodule 222, a data processing module 23, a timing module 24, a support leg 25, and a server 3. Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model embodiment provides a vehicle full-scale raw data acquisition system. See [link / reference] Figures 1 to 2 , Figure 1 This is a schematic diagram of the structure of a vehicle full-volume raw data acquisition system, which includes: a bracket 1, an on-board data acquisition device 2, and a server 3;

[0035] The vehicle-mounted data acquisition device 2 is mounted on the bracket 1;

[0036] The vehicle-mounted data acquisition device 2 includes a power supply module 21, a data mirroring device, and a data processing module 23;

[0037] The data processing module 23 is connected to the data mirroring device and the server 3 respectively. The data mirroring device is used to copy vehicle data and send the vehicle data to the data processing module 23 for mirror parsing. The data processing module 23 is used to monitor the vehicle data acquisition configuration and vehicle data upload configuration sent by the server 3 in real time, and upload the target data to the server according to the vehicle data acquisition configuration and vehicle data upload configuration. The vehicle data includes the target data.

[0038] The power supply module 21 is electrically connected to the data mirroring device and the data processing module 23.

[0039] It should be noted that the data mirroring device is a device capable of copying vehicle data without affecting the original vehicle information interaction, i.e., copying the original vehicle data, and sending the copied original vehicle data to the data processing module 23 for mirror parsing. The data processing module 23 then listens in real time to the vehicle-side data acquisition configuration and vehicle-side data upload configuration sent by the server 3, and uploads the target data to the server 3 according to the vehicle-side data acquisition configuration and vehicle-side data upload configuration. The data acquisition configuration mainly includes whether each sensor (LiDAR, millimeter-wave radar, camera) collects data, whether communication data between controllers is collected, whether controller logs are collected, whether controller 3D target and lane line perception results are collected, whether controller diagnostic data is collected, whether calibration data is collected, and whether the data sampling frequency is downsampled, etc. The vehicle-side data upload configuration adds filtering conditions to the data acquisition configuration, such as data within a certain period of time. The data processing module 23 can then listen to the vehicle-side data acquisition configuration and vehicle-side data upload configuration sent by the server 3, and upload the target data to the server 3 according to the vehicle-side data acquisition configuration and vehicle-side data upload configuration. Uploading the target data in this way can not only reduce data storage space, but also effectively reduce the bandwidth required for data transmission.

[0040] It is worth noting that the data processing module 23 of this application can not only collect the original vehicle data copied by the data mirroring device, but also parse the vehicle-side data collection configuration and vehicle-side data upload configuration, and determine whether the original vehicle data meets the conditions for uploading target data issued by the server 3 through the parsing results.

[0041] In this embodiment of the invention, the vehicle-mounted data acquisition device 2 is mounted on the bracket 1. The data processing module 23 of the vehicle-mounted data acquisition device 2 is communicatively connected to the data mirroring device and the server 3, respectively, so as to enable the data processing module 23 to upload target data to the server 3. The power supply module 21 is electrically connected to the data mirroring device and the data processing module 23. Through the vehicle full-volume raw data acquisition system disclosed above, the data processing module 23, through the vehicle-mounted data acquisition configuration and the target data required for vehicle-mounted data upload issued by the server 3, makes the target data uploaded to the server 3 by the data processing module 23 of this application smaller than the vehicle's original full-volume data. Therefore, compared with the existing data acquisition system, this application can not only reduce the data storage space, but also effectively reduce the bandwidth required for data transmission.

[0042] Specifically, the data mirroring device includes: a first data mirroring submodule 221 and a second data mirroring submodule 222;

[0043] The first data mirroring submodule 221 is used to connect to the original vehicle Ethernet communication link and to copy the original vehicle data in the original vehicle Ethernet communication link.

[0044] The second data mirroring submodule 222 is used to connect to the original vehicle video communication link and to copy the original vehicle video data in the original vehicle video communication link.

[0045] It should be noted that the first data mirroring submodule 221, which is connected to the original vehicle's Ethernet communication link, and the second data mirroring submodule 222, which is connected to the original vehicle's video communication link, can mirror different types of data respectively, effectively ensuring the replication of different types of data, while also ensuring the transmission efficiency of each type of data.

[0046] Furthermore, the power supply module 21 is also used to connect to the vehicle's battery.

[0047] It should be noted that connecting the power supply module 21 to the vehicle's battery ensures that the power supply equipment continuously provides power to the data mirroring device and the data processing module 23, thereby ensuring that the power supply module 21 does not need to be disassembled or replaced throughout its entire life cycle.

[0048] Preferably, the power supply module 21 is an energy storage battery.

[0049] It should be noted that the energy storage battery can be a lead-acid battery, a lithium-ion battery, a graphene battery, or other batteries capable of storing electrical energy. Those skilled in the art can choose according to their needs.

[0050] Furthermore, server 3 includes: a cloud acquisition port, a cloud upload port, and a cloud processor;

[0051] The cloud-based acquisition port transmits the acquired target data to the cloud processor.

[0052] The cloud upload port sends the vehicle-side acquisition configuration and vehicle-side upload configuration sent by the cloud processor to the vehicle-mounted data acquisition device 2.

[0053] It should be noted that the cloud upload port sends the vehicle-side acquisition configuration and vehicle-side upload configuration sent by the cloud processor to the vehicle-side data acquisition device 2. The vehicle-side data acquisition device 2 uploads the target data to the server 3 based on the vehicle-side acquisition configuration and vehicle-side upload configuration. The cloud acquisition port in the server 3 sends the target data through the acquisition data processing module 23 and then transmits it to the cloud processor, thus realizing the acquisition of the target data.

[0054] It should also be noted that the cloud processor mentioned above includes three vehicle-side data filtering operator management functions. The main operators include driving scene recognition operators such as tunnel and highway recognition operators, weather recognition operators, integrated navigation latitude and longitude threshold operators, CAN (Controller Area Network, a serial communication protocol bus for real-time applications) / CANFD (CAN with Flexible Datarate, an upgraded version of CAN) signal threshold operators, data frame loss verification operators, etc.

[0055] The vehicle data acquisition configuration sent from server 3 to vehicle-mounted data acquisition device 2 includes calibration data acquisition configuration, sensor data acquisition configuration, vehicle perception result acquisition configuration, vehicle log acquisition configuration, and vehicle communication message acquisition configuration. The vehicle data acquisition configuration sent from server 3 to the vehicle includes CAN / CAND bus message upload determination, frame rate reduction upload, latitude and longitude information upload if conditions are met, perception result upload if conditions are met, and signal change information upload.

[0056] Specifically, the data processing module 23 includes: an on-board data acquisition port, an on-board data storage device, an on-board upload port, and an on-board processor;

[0057] The vehicle data acquisition port collects original vehicle data, as well as the vehicle data acquisition configuration and vehicle data upload configuration sent by the acquisition server 3;

[0058] The vehicle-mounted data storage device stores the original vehicle data collected by the vehicle-mounted data acquisition port;

[0059] The vehicle-mounted processor filters target data based on the vehicle-mounted data acquisition configuration and the vehicle-end data upload configuration, and uploads it to the server 3 through the vehicle-mounted data upload port.

[0060] It should be noted that the original vehicle data is collected through the vehicle data acquisition port, and the vehicle data acquisition configuration and vehicle-end data upload configuration are sent by the acquisition server 3. The collected original vehicle data is then sent to the vehicle data storage device for storage. The vehicle processor filters the target data based on the vehicle data acquisition configuration and vehicle-end data upload configuration, and uploads it to the server 3 through the vehicle data upload port. This enables the upload of the required target data to the server 3. Compared with the existing full original vehicle data, the amount of data is reduced. Therefore, this application can reduce the data storage space and effectively reduce the bandwidth required for data transmission.

[0061] It should also be noted that the vehicle processor of this application can parse the physical signals sent by various sensors and convert them into recognizable messages.

[0062] The vehicle processor listens to the vehicle data acquisition configuration and vehicle-side data upload configuration sent by the server 3 via MQTT (Message Queuing TelemetryTransport, a lightweight publish / subscribe messaging protocol). It can save data in segments according to the actual length in the vehicle data acquisition configuration and perform real-time data filtering and labeling according to the operators in the vehicle-side data upload configuration. The labeled data is the target data and is finally uploaded to the server 3 via the MQTT protocol.

[0063] Specifically, the vehicle-mounted data acquisition device 2 also includes a timing module 24 for unifying the timestamps of sensors, vehicle domain control, and the vehicle-mounted data acquisition device 2 within the vehicle.

[0064] It should be noted that by setting the timing module 24 for unifying the timestamps of sensors, vehicle domain control and vehicle-mounted data acquisition devices 2 in the vehicle, it is ensured that the target data filtered by the vehicle processor based on the vehicle-mounted data acquisition configuration and the vehicle-mounted data upload configuration is data within the required time period.

[0065] Specifically, the data mirroring device is a switch.

[0066] It should be noted that the data mirroring device can be a switch or other types of devices capable of mirroring data in the vehicle communication link. Those skilled in the art can choose according to their needs.

[0067] Furthermore, bracket 1 is fixed inside the vehicle by bolts.

[0068] It should be noted that bracket 1 is fixed inside the vehicle with bolts to prevent bracket 1 from shaking inside the vehicle and to ensure the stability of the equipment operation.

[0069] It should also be noted that the bracket 1 can be fixed inside the vehicle by bolts, or by snap-fitting, welding or binding. Those skilled in the art can choose according to their needs.

[0070] Furthermore, the bracket 1 is fixed inside the vehicle by multiple support legs 25, wherein the support legs 25 are variable length support legs 25.

[0071] It should be noted that the bracket 1 is fixed inside the vehicle by multiple variable length support legs 25, which can improve the shock resistance of the on-board data acquisition device 2 when the vehicle passes through bumpy road sections.

[0072] Specifically, the bracket 1 is provided with support feet 25 at the top, bottom and sides.

[0073] It should be noted that by providing support feet 25 at the top, bottom and sides of the bracket 1, not only can the top and sides of the bracket 1 be prevented from impacting the vehicle's shell, but the shock resistance of the vehicle-mounted data acquisition device 2 can also be further improved.

[0074] To facilitate understanding of the vehicle full raw data acquisition system provided above, this utility model also provides the steps for vehicle full raw data acquisition.

[0075] Step 1: Server 3 selects all the data that needs to be collected from the vehicle in "Vehicle Data Acquisition Configuration".

[0076] Step 2: Server 3 selects an operator in the "Vehicle Data Filtering Operator Management Library" and sends the vehicle data upload configuration to the vehicle data acquisition device 2.

[0077] Step 3: The vehicle-mounted data acquisition device 2 is turned on and listens for the "vehicle-mounted data acquisition configuration" and "vehicle-mounted data upload configuration" sent by the server 3.

[0078] Step 4: The vehicle-mounted data acquisition device 2 and storage server 3 automatically store data according to the actual length and run data filtering operators to tag the target data packets to be uploaded.

[0079] Step 5: The vehicle-mounted data acquisition device 2 uploads the marked target data packets to the server 3.

[0080] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
