[0029] In order to be able to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In addition, in order to be able to understand the characteristics and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings, and the attached drawings are only for reference purposes and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided by multiple details. However, in the absence of these details, one or more embodiments can still be implemented. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0030] The data recording method provided in this embodiment is applied to a data recording device, which can be installed in the car screen hardware in the car. More specifically, it can be a car screen installed in the car, or it can be a car-mounted intelligent control screen or entertainment screen, or it can be other electronic devices with computing and communication functions that can communicate with the in-car domain information. The device or screen can communicate with the master controller responsible for handling the intra-domain / inter-domain communication of the vehicle.

[0031] In order to improve the problem that the current unmanned driving system is not convenient enough to obtain driving data, this embodiment proposes a data recording method. Figure 1 As shown, the method includes:

[0032] S101, when a data recording instruction sent from the cloud is obtained, the data recording instruction is parsed to obtain a target acquisition data type.

[0033] The data recording method in this embodiment is applied to the in-vehicle entertainment screen, and of course, more specifically, it can also be a device for data recording in the screen. First of all, the data recording instruction can be sent by the user to the car screen through the cloud, or the cloud can trigger the data recording instruction at a certain time point (for example, every ten minutes, or when a certain speed value is reached). When the car screen obtains the data recording instruction, the data recording instruction is parsed to obtain the target collection data type. Determine the target collection data type, for example, by identifying customized topic information to determine the type of data to be identified.

[0034] Specifically, the communication from the cloud to the vehicle screen, and from the vehicle screen to the vehicle controller can be realized by activating the developer mode from the cloud, turning on the developer options to enable higher control permissions to realize the cloud-to-vehicle screen command input. At the same time, the device identification code of the vehicle entertainment screen, such as the device ID (Identification, identification code), can be added to the vehicle controller in the development kit, so that the controller of the vehicle smart screen (such as the former 8155 chip, etc.) can realize intra-domain communication with the unmanned driving controller. The specific method is not limited, it only needs to ensure that the communication from the cloud to the vehicle screen, and from the vehicle screen to the vehicle controller can be realized.

[0035] S102, sending a data collection instruction to the vehicle controller.

[0036] The data collection instruction is used to instruct the vehicle controller to collect target data, and the data collection instruction includes the target data type. After the vehicle-mounted screen determines the target data type, the data collection instruction is sent to the vehicle controller.

[0037] S103, receiving target acquisition data fed back by the vehicle controller.

[0038] S104, sending the target acquisition data to the recording layer for recording.

[0039] The data recording here refers to the process of uploading data to the cloud or directly writing it to a readable storage medium such as a hard disk. At the same time, in this embodiment, due to the unmanned driving environment, the data recording includes two types of data, one is DDS (Data Distribution Service) data, and the other is point cloud data. DDS uses Topic as a unit, and the application can determine the type of data it contains through Topic without relying on other context information. At the same time, DDS can automatically store, publish or subscribe to data in a user-defined manner, allowing applications to write or read data like accessing local data. Point cloud data is a data set of points in a certain coordinate system. It contains rich information, including three-dimensional coordinates X, Y, Z, color, classification value, intensity value, time, etc. In addition, the specific acquisition method of video point cloud data can be obtained through the ZMQ service of the vehicle controller. In this case, the type of data will also be different, for example, it may be the speed value of a certain time node, and it may also be the speed of a time span or the driving conditions during that period of time.

[0040] In this embodiment, first, when the on-board smart screen obtains the data recording instruction sent from the cloud, it parses the data recording instruction to obtain the target data collection type. The data recording instruction can be sent from the cloud or through inter-domain communication, timed triggering, etc. Then send the data collection instruction to the vehicle controller; the data collection instruction is used to instruct the vehicle controller to collect the target collection data, and the data collection instruction contains the target collection data type. The on-board smart screen receives the target collection data fed back by the vehicle controller, and sends the target collection data to the recording layer for recording. Compared with the related art, this embodiment essentially borrows the characteristics of the smart screen with computing functions, and uses it as a medium for the vehicle master controller to interact with the outside world, which greatly alleviates the computing burden of the vehicle controller, and can also achieve data acquisition and recording without connecting to other hardware, thereby improving the convenience of data acquisition and recording.

[0041] It should be noted that the current unmanned driving or automatic driving, when acquiring data or debugging parameters, all involves connecting the unmanned driving controller (FSD, Full self-driving) to the outside (such as vehicle Ethernet) and then recording the data through a conversion box to a computer. Different from the traditional driving method, in unmanned driving technology, it is particularly important to obtain the driving data of the vehicle and improve the parameters of the vehicle based on the data. However, this method is more cumbersome and prone to disconnection. The data recording scheme in this embodiment, without connecting to other hardware, uses the characteristics of the on-board smart screen with computing and processing functions, and uses it as an auxiliary external processor, so that data can be obtained for debugging by communicating with the on-board smart screen, which improves the convenience in data acquisition and recording.

[0042] Optionally, sending the target acquisition data to the recording layer for recording includes: sending the target acquisition data to the recording layer for recording at a preset time interval; and / or sending the target acquisition data to the recording layer for recording at a preset data packet size.

[0043] In this embodiment, the recording layer can be completed in the Java layer, and the current layer can be in the native layer of the local framework. The target acquisition data fed back by the FSD controller can be subscribed and received in the native layer. Furthermore, when the target acquisition data is transmitted to the Java layer, it can be transmitted once at a preset time interval (such as every 50 seconds), or transmitted to the Java layer in a data packet of a preset capacity; or it can be a combination of the two. This transmission method can make data transmission smoother.

[0044] Optionally, after receiving the target acquisition data fed back by the vehicle controller, the method further includes: receiving a sending timestamp of the target acquisition data; recording a receiving timestamp of the received target acquisition data; and performing time alignment processing on the sending timestamp and receiving timestamp of the target acquisition data.

[0045] In this embodiment, when the smart screen receives the target acquisition data fed back by the FSD controller, it can also receive the data sending timestamp fed back by the FSD controller, and record the receiving timestamp of the current target acquisition data. This is also based on the calculation and processing function of the smart screen. After obtaining the sending timestamp and the receiving timestamp, the target acquisition data can also be time-aligned according to the two timestamps. In addition, the way to obtain the sending timestamp can be that the FSD controller feeds back the target acquisition data and then sends the sending time corresponding to the target acquisition data; or it can be that the timestamp is directly attached to the target acquisition data and sent together, reducing the signaling burden. The time alignment processing here briefly refers to the standardization and alignment of the data time when multiple different sensors transmit data. It is necessary in multi-sensor data transmission and will not be explained in detail here.

[0046] It should be noted that in the related art, ordinary data recording can only record different information separately, because usually using data lines or ordinary single-function acquisition devices, they do not have computing functions, that is, they cannot complete the acquisition of data while recording the sending time and receiving time, and perform time alignment processing on the data. In this embodiment, the time alignment processing function of the data can be realized based on the computing power of the smart screen without adding hardware.

[0047] Optionally, sending the target acquisition data to a recording layer for recording further includes: sending the target acquisition data that has completed the time alignment processing, and a sending timestamp and a receiving timestamp corresponding to the target acquisition data to a recording layer for recording.

[0048] In this embodiment, the target acquisition data and the corresponding time data after time alignment are sent to the recording layer for recording. The Java layer can perform subsequent inspection processing on the data according to the corresponding timestamp and display the recording time. For example, data verification or reliability inspection is performed on a certain acquisition data according to the timeline. This improves the standardization and availability of the data.

[0049] Optionally, sending the target acquisition data to the recording layer for recording further includes: sending additional information of the target acquisition data to the recording layer for recording; the additional information includes: data size information of the target acquisition data and frame loss information of the target acquisition data during transmission

[0050] In this embodiment, the frame loss information and the current data size information are sent to the Java layer, so that the Java layer can display relevant data recording information, such as the frame loss rate and the data size, to the user.

[0051] Optionally, the target acquisition data type includes a DDS data type and a video point cloud data type.

[0052] In this embodiment, due to the unmanned driving environment, the data recording includes two types of data: DDS data and video point cloud data. Among them, point cloud data is a data set of points in a certain coordinate system. It contains rich information, including three-dimensional coordinates X, Y, Z, color, classification value, intensity value, time, etc. In some cases, point cloud data will also include driving data for a period of time, such as comprehensive data including current driving conditions, driving speed, component temperature, etc. This type of data can also be uploaded to the recording layer as target acquisition data for recording.

[0053] like Figure 2 As shown, a flow chart of another data recording method provided in an embodiment of the present application is shown, including the interaction process of multiple devices in the scheme, and the method includes:

[0054] S201, the user sends a data recording instruction through the cloud.

[0055] In this step, the data recording instruction can be obtained by the user sending it to the car screen through the cloud, or the cloud can trigger the data recording instruction at a certain time point (for example, every ten minutes, or when a certain speed value is reached). The communication from the cloud to the car screen and from the car screen to the vehicle controller can be specifically realized by activating the developer mode from the cloud and opening a higher control authority to realize the command input from the cloud to the car screen. At the same time, the device identification code of the car entertainment screen, such as the device ID (Identification, identification code), can be added to the vehicle controller in the development kit to realize the communication between the two. The specific method is not limited, it only needs to ensure that the communication from the cloud to the car screen and the car screen to the vehicle controller can be realized.

[0056] S202, the vehicle-mounted smart screen receives and parses the data recording instruction to obtain the target collection data type.

[0057] The data collection instruction is used to instruct the vehicle controller to collect target collection data, and the data collection instruction contains the target collection data type.

[0058] S203, the vehicle-mounted smart screen sends a data collection instruction to the vehicle controller.

[0059] After the vehicle-mounted screen determines the target data type, it sends a data collection instruction to the vehicle controller to let the vehicle controller know which data to collect.

[0060] S204, the vehicle controller receives the data collection instruction and parses it to obtain the target data collection type.

[0061] The data types include two types of data, one is DDS (Data Distribution Service) data, and the other is point cloud data. DDS uses Topic as a unit, and the application can determine the data type it contains through Topic without relying on other contextual information. At the same time, DDS can automatically store, publish or subscribe to data in a user-defined manner, allowing applications to write or read data like accessing local data. Point cloud data is a data set of points in a certain coordinate system. It contains rich information, including three-dimensional coordinates X, Y, Z, color, classification value, intensity value, time, etc. In this case, the type of data will also be different. For example, it may be the speed value at a certain time node, or it may be the speed over a period of time or the driving conditions during that period of time.

[0062] In addition, according to the specific application scenario, this topic can be parsed specifically to meet the special monitoring needs of certain quality inspection departments for a certain variable. For example, by adding abnormal situation configuration words to the target collection data type sent from the cloud, the monitoring needs of this variable can be obtained in the subsequent parsing.

[0063] S205: The vehicle controller obtains the target collection data and provides feedback to the vehicle-mounted smart screen.

[0064] When the smart screen receives the target acquisition data sent by the vehicle controller, it can also obtain the sending timestamp of the target acquisition data fed back by the vehicle controller and the receiving timestamp of the target acquisition data received, and perform time alignment processing on the target acquisition data according to these two timestamps.

[0065] S206, the vehicle-mounted smart screen sends the target collected data to the recording layer or the cloud for recording.

[0066] When sending the target collected data to the recording layer, it can be transmitted at a preset time interval (such as every 50 seconds), or transmitted to the Java layer in a data packet of a preset capacity; or it can be a combination of the two. This transmission method can make data transmission more stable.

[0067] In the above embodiment, first, when the vehicle-mounted smart screen obtains the data recording instruction issued by the cloud, it parses the data recording instruction to obtain the target data type. The data recording instruction can be issued by the cloud or by inter-domain communication, timed triggering, etc. Then send the data acquisition instruction to the vehicle controller; the data acquisition instruction is used to instruct the vehicle controller to collect the target data, and the data acquisition instruction contains the target data type. The vehicle-mounted smart screen receives the target acquisition data fed back by the vehicle controller and sends the target acquisition data to the recording layer for recording. Compared with the relevant technology, the essence of this embodiment is to borrow the characteristics of the smart screen with computing function, and use it as a medium for the vehicle master controller to interact with the outside world, which greatly alleviates the computing burden of the vehicle controller, and can also realize data acquisition and recording without connecting to other hardware, which improves the convenience of data acquisition and recording. In the whole process, the user only needs to choose to start the recording mode, and the data recording process can be completed by clicking the record, pause, end and other buttons, and the size of the data, acquisition time, recording duration and other information can be fully seen.

[0068] At present, when acquiring data or debugging parameters, the unmanned driving or automatic driving is done by connecting the unmanned driving controller (FSD, Full self-driving) to the outside (such as vehicle Ethernet) and then recording the data through a conversion box to a computer. Different from the traditional driving method, in unmanned driving technology, it is particularly important to obtain the driving data of the vehicle and improve the parameters of the vehicle based on the data. However, this method is more troublesome and prone to disconnection. The data recording scheme in this embodiment, without connecting to other hardware, uses the characteristics of the vehicle-mounted smart screen with computing and processing functions, and uses it as an auxiliary external processor, so that data can be obtained for debugging by communicating with the vehicle-mounted smart screen, which improves the convenience in data acquisition and recording.

[0069] At the same time, compared with the related art, the ordinary data recording in the related art can only record different information separately, because the data line or the ordinary single-function acquisition device usually adopts, which does not have the computing function, that is, it cannot complete the acquisition of data while recording the sending time and receiving time, and perform time alignment processing on the data. However, in this embodiment, the time alignment processing function of the data can be realized based on the computing power of the smart screen without adding hardware.

[0070] Further, as Figure 1 and Figure 2 The specific implementation of the method shown in the embodiment provides a data recording device, such as Figure 3As shown, the device includes: a parsing unit 301, a sending unit 302, a receiving unit 303 and a processing unit 304.

[0072] The sending unit 302 is configured to send a data acquisition instruction to the vehicle controller; the data acquisition instruction is used to instruct the vehicle controller to collect target acquisition data, and the data acquisition instruction contains the target acquisition data type;

[0073] The receiving unit 303 is configured to receive the target acquisition data fed back by the vehicle controller;

[0074] The processing unit 304 is configured to send the target acquisition data to the recording layer for recording.

[0075] In a specific application scenario, the processing unit 304 is specifically configured to send the target acquisition data to the recording layer for recording at a preset time interval; and / or send the target acquisition data to the recording layer for recording at a preset data packet size.

[0076] In a specific application scenario, the receiving unit 303 is further configured to receive a sending timestamp of the target acquisition data; record a receiving timestamp of the target acquisition data; and perform time alignment processing on the sending timestamp and the receiving timestamp of the target acquisition data.

[0077] In a specific application scenario, the processing unit 304 is further configured to send the target acquisition data that has completed the time alignment processing, as well as the sending timestamp and receiving timestamp corresponding to the target acquisition data, to the recording layer for recording.

[0078] In a specific application scenario, the processing unit 304 is further configured to send additional information of the target acquisition data to the recording layer for recording; the additional information includes: data size information of the target acquisition data and frame loss information of the target acquisition data during transmission.
