[0029] Example 1

[0030] Figure 1 A flowchart of a data acquisition method applied to a server is provided for the first embodiment of the present invention. The embodiment of the present invention is applicable to scenarios where vehicle status data can be flexibly collected. The method can be executed by a data acquisition system. The data acquisition system can be implemented in the form of hardware and / or software. The data acquisition system can be configured in an electronic device. Figure 1 As shown, the method includes:

[0031] S110 : Determine a target control local area network bus in the vehicle according to business requirements, and determine a database container file corresponding to the target control local area network bus.

[0032] The target CAN bus refers to a specific bus channel within the CAN bus, selected based on business requirements, for collecting specific vehicle status data. A vehicle contains multiple CAN buses, each transmitting different types of vehicle status data. The target CAN bus is matched based on business requirements.

[0033] A database container file can be understood as a structured file that stores various types of vehicle data and the logic for collecting that data. It is used to capture data on the LAN bus. For example, a database container file includes, but is not limited to, the data content, start time, and / or frequency of data collection. The database container file specifies the scope of data that can be collected and can accurately determine the data transmitted on the target LAN bus within the vehicle.

[0034] Specifically, by consulting the vehicle's technical documentation, the target control area network bus corresponding to different business requirements and the database container file corresponding to the target control area network bus can be identified. Alternatively, by using vehicle monitoring tools to scan and analyze the vehicle's network architecture, the target control area network bus that meets the business requirements can be automatically identified and the database container file corresponding to the target control area network bus can be obtained. The database container file can correspond to the bus identifier of the target control area network bus or the physical number of the target control area network bus.

[0035] S120: Construct a data collection signal based on the database container file and business requirements.

[0036] The data acquisition signal can be understood as an instruction to trigger data acquisition, which can be used to clarify data information such as data content, start time and / or acquisition frequency of the data acquisition.

[0037] Specifically, based on the various types of data stored in the database container file and in conjunction with specific business requirements, a data acquisition signal is constructed by writing script code or using a specific signal generation tool to specify data information such as the bus location, start time, and / or acquisition frequency for data acquisition. The embodiments of the present invention do not limit the specific signal generation tool.

[0038] S130: Acquire vehicle status data of the vehicle according to the data acquisition signal.

[0039] Vehicle status data refers to a series of data generated by a vehicle during driving, which is used to reflect the vehicle's operating status. For example, the data type of the vehicle status data may include numeric type and bus type, and the data content of the vehicle status data may include vehicle speed and vehicle position.

[0040] Specifically, a data acquisition signal is obtained for clarifying acquisition parameters such as data content, start time and / or acquisition frequency of data acquisition, and according to the acquisition signal, the target control local area network bus is monitored to capture the vehicle status data generated by the vehicle during driving from the target control local area network bus.

[0041] In an embodiment of the present invention, a target control area network bus within a vehicle is determined based on business requirements, along with a corresponding database container file. A data acquisition signal is constructed based on the database container file and business requirements, and vehicle status data is acquired based on the data acquisition signal. By dynamically matching the target control area network bus with the corresponding database container file based on business requirements, this embodiment of the present invention accurately locates the source of required data, avoids collecting irrelevant data, and improves data collection accuracy. Furthermore, the data acquisition signal can be custom-built based on the database container file and business requirements, enhancing data collection flexibility.

[0042] Example 2

[0043] Figure 2 A flowchart of a data acquisition method applied to a vehicle is provided for the second embodiment of the present invention. The embodiment of the present invention is applicable to scenarios where vehicle status data can be flexibly acquired. The method can be executed by a data acquisition system. The data acquisition system can be implemented in the form of hardware and / or software. The data acquisition system can be configured in an electronic device. Figure 2 As shown, the method includes:

[0044] S210: Obtain a data acquisition signal sent by the server.

[0045] Specifically, the data acquisition signal sent by the server is received through a communication interface inside the vehicle or by utilizing a sensor installed inside the vehicle.

[0046] S220 . Collect vehicle status data according to the database container file carried by the data collection signal.

[0047] Specifically, after receiving a data acquisition signal from a server via a vehicle's internal communication interface or using sensors installed within the vehicle, the data acquisition information is transmitted to an electronic component within the vehicle responsible for collecting vehicle status data. The electronic component is then controlled to parse the data acquisition signal to extract a database container file, and collect vehicle status data based on the data content, start time, and / or acquisition frequency specified in the database container file. It is understood that this vehicle status data refers to the vehicle status data on the target control area network bus within the vehicle.

[0048] S230: Upload vehicle status data to the server.

[0049] Specifically, the collected vehicle status data can be uploaded to the server in real time via a wired or wireless network, or the vehicle status data can be uploaded to the server according to an upload cycle. In embodiments of the present invention, the data acquisition signal can also include an upload cycle for uploading the vehicle status data to the server. The vehicle status data is uploaded to the server according to the upload cycle. If the upload cycle has not yet arrived, the vehicle status data can be temporarily stored in a local storage device in the vehicle.

[0050] This embodiment of the present invention receives a data acquisition signal sent by a server, controls a vehicle to collect vehicle status data according to a database container file carried in the data acquisition signal, and uploads the collected vehicle status data to the server. By collecting vehicle status data according to the database container file carried in the data acquisition signal, this embodiment of the present invention ensures the accuracy of vehicle status data collection.

[0051] Example 3

[0052] Figure 3 A flowchart of another data collection method applied to the server side is provided for the third embodiment of the present invention. The embodiment of the present invention is a refinement of the above embodiment. Specifically, it refines the specific steps of how to determine the database container file, how to construct the data collection signal, and how to obtain the vehicle data status.

[0053] like Figure 3 As shown, another data collection method applied to the server side may include the following specific steps:

[0054] S310: Call a preset business page to collect business requirements, where the business requirements at least include a target control local area network bus identifier and data collection configuration information.

[0055] The preset business page refers to a user interface pre-configured on the server side, through which the user inputs, selects and / or confirms the vehicle status data to be collected.

[0056] Business requirements refer to the specific requirements of users for vehicle status data collection, which can reflect the business goals that users hope to achieve by collecting vehicle data. For example, business requirements at least include the target control area network bus identifier and data collection configuration information. The target control area network bus identifier can be understood as a symbol that uniquely identifies a specific control area network bus within the vehicle, indicating which control area network bus in the vehicle is the target control area network bus for this data collection. The data collection configuration information can be understood as a set of parameters used to describe the specific details of the collection operation. For example, the data collection configuration information at least includes the signal identifier, signal value type, upload signal type, data collection period, and data reporting period.

[0057] Specifically, the preset business page is started, and the user enters, selects and / or confirms the vehicle status data to be collected in the preset business page by clicking a button or menu item in the preset business page, and calls the preset business page to collect the business needs for vehicle status data collection through a programming interface or command line tool.

[0058] S320: Send the target control area network bus identifier to the vehicle to obtain control area network bus information fed back by the vehicle with respect to the target control area network bus identifier.

[0059] The target control area network bus identifier refers to a character used to uniquely identify a specific control area network bus inside a vehicle. Through the target control area network bus identifier, the target control area network bus inside the vehicle from which data needs to be collected can be accurately located.

[0060] Control area network bus information refers to a series of information used to describe the control area network bus communication in the vehicle. For example, the control area network bus information at least includes information such as node description, message description and signal description. Node description refers to information about electronic components transmitted on the control area network bus. For example, the node description may include information such as component identification and component function; message description refers to information such as the structure, identification and length of the data packet transmitted on the control area network bus. Signal description refers to the specific data field in the message description. For example, the signal description may include information such as vehicle speed and component temperature.

[0061] Specifically, the target control LAN bus identifier of the target control LAN bus is sent to the vehicle end through a network communication protocol or a direct connection, and the vehicle end feeds back control LAN bus information such as node description, message description and signal description transmitted on the target control LAN bus inside the vehicle based on the target control LAN bus identifier.

[0062] S330: Construct a database container file according to the control LAN bus information.

[0063] Specifically, the control LAN bus information fed back by the vehicle end is obtained, and node description, message description, signal description and other information are extracted from the control LAN bus information through a database container file generation tool or a bus analysis tool. A database container file is generated based on the parsed node description, message description and signal description and other information. The database container file clarifies the data range of the collectible data and is used to guide subsequent data collection work.

[0064] S340: Determine the communication connection protocol corresponding to the vehicle.

[0065] Specifically, by consulting the vehicle's technical documentation or using a vehicle diagnostic tool to determine the communication connection protocol used by the vehicle, it is possible to ensure that the server communicates correctly with the vehicle's internal control LAN bus.

[0066] S350: Encapsulate the database container file and the data collection configuration information required by the business into a data collection signal according to the communication connection protocol.

[0067] Among them, the data acquisition configuration information includes signal identification, signal value type, upload signal type, data acquisition period and data reporting period; signal identification refers to the unique number of the signal to be collected, which is used to distinguish the various types of signals to be collected; signal value type refers to the type of signal value of the signal to be collected. For example, the signal value type may include physical value or bus value; upload signal type refers to the method of signal transmission. For example, the upload signal type may include real-time transmission or scheduled transmission.

[0068] Specifically, according to the determined communication connection protocol, the database container file and the data collection configuration information required by the business are encapsulated into a data collection signal, and the data collection signal includes all parameters required in the data collection process.

[0069] S360: Call a preset business page to collect vehicle operation restrictions.

[0070] Among them, the operation restrictions can be understood as the restriction conditions set in the vehicle data collection process, and the operation restrictions include at least one of the following: the signal identifier of the data collection signal sent is not repeated; the signal identifier of the data collection signal sent matches the database container file, which is used to ensure the uniqueness and effectiveness of the data collection process.

[0071] Specifically, the preset business page is started, and the user sets the operation restrictions during the vehicle data collection process in the preset business page by clicking a button or menu item in the preset business page, and calls the preset business page to collect operation restrictions through a programming interface or command line tool.

[0072] S370: Send a data collection signal to the vehicle according to the operation restriction, so that the vehicle collects vehicle status data according to the data collection signal.

[0073] Specifically, after obtaining the vehicle's operating restrictions and ensuring that the data acquisition signal meets the restrictions specified by the operating restrictions, for example, the restrictions may include signal identification uniqueness and matching with information such as the file identification or file name of the database container file, the data acquisition signal is sent to the vehicle, and the vehicle is controlled to collect vehicle status data of the vehicle based on the received data acquisition signal.

[0074] S380: Obtain vehicle status data reported by the vehicle according to a data reporting period carried by the data acquisition signal.

[0075] Specifically, after the vehicle receives the data acquisition signal, the vehicle is controlled to parse the data acquisition signal and obtain the data reporting period carried in the data acquisition signal. According to the data reporting period, the vehicle is controlled to periodically transmit the collected vehicle status data to the server, and the server obtains the vehicle status data transmitted periodically by the vehicle according to the data reporting period.

[0076] In an embodiment of the present invention, a preset business page is called to collect business requirements, where the business requirements include at least a target control LAN bus identifier and data collection configuration information. The target control LAN bus identifier is sent to a vehicle to obtain control LAN bus information fed back by the vehicle for the target control LAN bus identifier. A database container file is constructed according to the control LAN bus information, a communication connection protocol corresponding to the vehicle is determined, and the database container file and the data collection configuration information of the business requirements are encapsulated as a data collection signal according to the communication connection protocol. The preset business page is called to collect operation restrictions of the vehicle, and the data collection signal is sent to the vehicle according to the operation restrictions, so that the vehicle collects vehicle status data according to the data collection signal, so that the server side obtains the vehicle status data reported by the vehicle according to the data reporting period carried by the data collection signal. The embodiment of the present invention can provide a unified configuration entry through a preset business page, simplify the configuration process of data acquisition parameters, and improve the accuracy and effectiveness of data acquisition; clarify the acquisition target by issuing a target control LAN bus identifier, thereby ensuring the accuracy of data acquisition; construct a database container file based on the LAN bus information, so that the file clarifies the data range of the collectible data, thereby ensuring the effectiveness of data acquisition; and ensure the compliance of the data acquisition process by sending a data acquisition signal that meets the operation restrictions, thereby improving the data acquisition efficiency.

[0077] Example 4

[0078] Figure 4 A flowchart of another data collection method applied to a vehicle is provided for the fourth embodiment of the present invention. The embodiment of the present invention is a refinement of the above embodiment. Specifically, it refines the specific steps of how to obtain the data collection signal sent by the server, how to collect vehicle status data according to the database container file carried by the data collection signal, and how to upload the vehicle status data to the server.

[0079] like Figure 4 As shown, another data collection method applied to the vehicle side may include the following specific steps:

[0080] S410: Receive a data acquisition signal sent by the server through a communication connection protocol.

[0081] Specifically, the server uses a defined communication connection protocol, such as the Transmission Control Protocol (TCP) or the Internet Protocol (IP), to send the data acquisition signal to the vehicle. The vehicle receives the data acquisition signal sent by the server through on-board 4G, 5G or Wi-Fi modules based on communication connection protocols such as TCP or IP.

[0082] S420: Determine, based on the signal identifier of the data acquisition signal, that the data acquisition signal is a newly added data acquisition signal.

[0083] Specifically, the signal identifier in the received data acquisition signal is parsed, and whether the data acquisition signal has existed in the vehicle is determined through a hash matching method or matching with a preset identifier list. If not, the data acquisition signal is determined to be a new data acquisition signal, and subsequent operations are performed based on the new data acquisition signal.

[0084] S430: Verify the data acquisition signal and analyze the data acquisition signal to obtain a database container file.

[0085] Specifically, the data acquisition signal is verified. For example, verification methods may include MD5 verification or digital signature verification to ensure data integrity and legitimacy. After the data acquisition signal passes the verification, the download address of the database container file is extracted from the data acquisition signal, and the database container file is downloaded according to the download address.

[0086] S440: Extract node description, message description, and signal description from the database container file.

[0087] Specifically, the database container file is parsed, and node descriptions, message descriptions, and signal descriptions are extracted from the parsed database container file. These description information are used to guide the vehicle to perform subsequent data collection work.

[0088] S450: Collect signal data in the vehicle according to the node description, message description, and signal description to construct a signal matrix.

[0089] The signal matrix refers to a matrix composed of various signal data in the vehicle, which is used to reflect the status of the vehicle.

[0090] Specifically, the vehicle collects signal data within the vehicle based on the node description, message description, and signal description. The vehicle organizes the collected signal data into a signal matrix according to a predetermined format, or converts the signal data into the form of a signal matrix by using a matrix construction algorithm.

[0091] S460: Use the signal matrix, the control local area network channel configuration corresponding to the signal matrix, and the identification code of the signal data in the signal matrix as vehicle status data.

[0092] The LAN channel configuration refers to the physical channel allocation information for the vehicle's LAN bus, used to determine the specific bus location for signal acquisition. For example, the LAN channel configuration could be Channel 1, corresponding to the powertrain LAN bus, or Channel 2, corresponding to the body LAN bus. The above LAN channel configurations are provided for illustrative purposes only to facilitate understanding.

[0093] The identification code refers to a unique code assigned to each signal in the signal matrix. For example, the identification code for temperature may be 110 and the identification code for vehicle speed may be 120. The identification code allows the server to quickly identify the signal type.

[0094] Specifically, the control local area network channel configuration corresponding to the signal matrix and the identification code of the signal data in the signal matrix are obtained, and the constructed signal matrix, control local area network channel configuration and identification code are combined together to form vehicle status data.

[0095] S470: Analyze the data acquisition signal to obtain a data reporting period.

[0096] Specifically, the vehicle further analyzes the data acquisition signal and extracts information about the data reporting cycle in the data acquisition signal. This information will determine when the vehicle reports the vehicle status data to the server.

[0097] S480: Report the vehicle status data to the server according to the data reporting cycle.

[0098] Specifically, the vehicle reports the vehicle status data to the server through a wireless communication module or a wired interface according to the data reporting cycle obtained by the analysis.

[0099] An embodiment of the present invention receives a data acquisition signal sent by a server through a communication connection protocol, determines that the data acquisition signal is a newly added data acquisition signal based on a signal identifier of the data acquisition signal, verifies the newly added data acquisition signal, and parses the newly added data acquisition signal to obtain a database container file, extracts a node description, a message description, and a signal description of the database container file, collects signal data in a vehicle according to the node description, the message description, and the signal description to construct a signal matrix, uses the signal matrix, the control local area network channel configuration corresponding to the signal matrix, and the identification code of the signal data in the signal matrix as vehicle status data, parses the data acquisition signal to obtain a data reporting cycle, and reports the vehicle status data to the server according to the data reporting cycle. The embodiment of the present invention avoids the duplication of data collection work and improves the data collection efficiency by performing subsequent data collection work based on the newly added data collection signal; by verifying the received data collection signal, it can ensure that the data collection signal has no errors or damage during the transmission process, thereby ensuring the accuracy and reliability of subsequent data collection; using the signal matrix and related information as vehicle status data can ensure that the vehicle status data can fully reflect the vehicle status information; by transmitting data according to a fixed data reporting cycle, it can be convenient for the server to classify, store and manage data, thereby improving data processing efficiency.

[0100] Example 5

[0101] Figure 5 This is a flow chart of a data collection method provided by the fifth embodiment of the present invention. The embodiment of the present invention is an integration of the above embodiments. Specifically, a data collection method applied to the server side and a data collection method applied to the vehicle side are integrated. Figure 5 As shown, the method includes:

[0102] The server-side operator configures the target signal that needs to be collected from the vehicle side as a database container file (DatabaseContainer File, DBC), configures the data type (physical value or bus value, etc.) of the data that needs to be reported from the vehicle side as an operation instruction, configures the reporting period of the data that needs to be reported from the vehicle side as an operation instruction, configures the collection frequency of the data that needs to be collected from the vehicle side as an operation instruction, and can also configure the storage path of the DBC file as an operation instruction. It is worth noting that the server-side operator can flexibly configure the DBC file, collection instructions and DBC file identifier according to different application scenarios. When the server-side collects the vehicle-side data, the service page of the server side will impose operation restrictions, which at least include that the signal identifier of the data collection signal issued is not repeated; the signal identifier of the data collection signal issued matches the database container file to prevent misoperation; the collection request includes the DBC file and various operation instructions.

[0103] When the vehicle is powered on, it actively establishes communication with the server. The server sends a collection request to the vehicle. After receiving the collection request, the vehicle parses the operation instructions in the collection request according to the network application protocol and downloads the corresponding DBC file from the server according to the file storage address in the operation instruction. The downloaded DBC file is verified, and the verification operation at least includes MD5 code verification. According to the DBC file format specification, the DBC file is parsed to obtain a list of signals to be collected. The microcontroller unit (MCU) on the vehicle collects the vehicle driving data on the Controller Area Network (CAN) bus based on the obtained data. The MCU encapsulates the collected vehicle driving data, the CAN channel identifier corresponding to the vehicle driving data, and the identification code of the vehicle driving data in the corresponding protocol into vehicle status data and reports it to the server. The data type of the vehicle driving data can be a physical value or a bus value. The frequency of the MCU collecting vehicle driving data and the reporting period of the MCU reporting vehicle status data are all obtained through the operation instructions in the collection request sent by the server.

[0104] Furthermore, in this embodiment of the present invention, server-side operators can configure commands for deleting, updating, and querying DBC files based on different application scenarios. Based on these commands, the server can delete, update, and query BDC files already downloaded by the vehicle, and return the results to the remote end. On the vehicle side, multiple DBC files can be processed simultaneously.

[0105] Furthermore, in an embodiment of the present invention, when the reporting period of the vehicle status data has not been reached, the vehicle status data is stored in a local buffer.

[0106] Furthermore, in an embodiment of the present invention, the vehicle can collect data by self-querying upon power-on.
