Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0023] The data packet structures of existing two-wheeled electric vehicles are not unified, resulting in a cumbersome development process and weak scalability and flexibility of the control system, which affects the intelligent development of two-wheeled electric vehicles.

[0024] In view of the above problems, a data processing method for two-wheeled electric vehicles and its cloud control system are proposed.

[0025] In a first aspect, a data processing method for two-wheeled electric vehicles is provided for processing the data of two-wheeled electric vehicles, and the following technical solutions are adopted, such as Figure 1 , Figure 1 is a flowchart of an embodiment of a data processing method for two-wheeled electric vehicles of the present application; it includes: S100. Classify the functions of the two-wheel electric vehicle modularly to obtain a basic information module, a GPS function information module, a control function module, a lighting function information module, and a user-defined information module, and further divide the sub-function information of each function module.

[0026] In a preferred embodiment, as Figure 2 , Figure 2 is Figure 1 a flowchart of a specific implementation of S100 in ; S100 includes: S110. Further divide the basic information module into vehicle unique identification information, vehicle type information, product production time, software version number, and hardware version number; S120. Further divide the GPS function information module into longitude, latitude, speed, and heading angle; S130. Further divide the control function module into control signal identification and speed limit; S140. Further divide the lighting function module into headlight, turn signal, and brake light.

[0027] The data packet structure information tables of the basic information module, the GPS function information module, the control function module, and the lighting function information module are shown in Table 1, Table 2, Table 3, and Table 4 respectively.

[0028] Table 1 Data Packet Structure Information Table of Basic Information Module Table 2 Data Packet Structure Information Table of GPS Function Information Module Table 3 Data Packet Structure Information Table of Control Function Information Module Table 4 Data Packet Structure Information Table of Lighting Function Information Module For example, the sub-function information of the basic information module is respectively VehicleID (vehicle unique identification), VehicleType (vehicle type), ProductionDate (production timestamp), SoftwareVersion (software version number), and HardwareVersion (hardware version number).

[0029] S200. Assign an ID to each function module, define the ID as the index byte of the data packet structure of the function module, define the data length and data type of each sub-function information in the function module, and define the union data of each sub-function information using the ID.

[0030] Data is exchanged in a common format and parsed at the application layer through a predefined data structure. The predefined data structure is indexed by an ID, and each ID corresponds to a different data structure. It is equivalent to each ID being an object, and through these IDs, data can be interacted between different applications. To achieve the purposes of vehicle identification, control, and monitoring.

[0031] When dealing with the data packet structure, take the basic information module as an example: First, define the ID content / / ID_BASE_INFO typedef struct { Double ID_MOTO; Uint16_t MOT_TYP Uint32_t PN_TIM; / / Timestamp …; Uint16_t SW_VER; Uint16_t HW_VER; }ID_BASE0001; typedef uion{ ID_BASE0001 myID_BASE; uint8_t ID_DATAPKT[SIZEOF(ID_BASE0001)]; } ID_BASE_PKT_InitTypeDef; Associate the ID with the corresponding data, which can also be understood as naming the corresponding functional data with the ID.

[0032] Secondly, define the union data ID_BASE_PKT_InitTypeDef ID_Base; Initialize the data ID_Base.myID_BASE.ID_MOTO = the defined vehicle information code; ID_Base.myID_BASE.MOT_TYP = the defined vehicle type; …

[0033] Define the union data. The data elements in the union can share the same storage partition.

[0034] In this embodiment, the role of defining the union data is to more conveniently convert the data into a byte stream, thereby simplifying network transmission, data storage, and hardware interaction.

[0035] In C language, the conversion of any data type to a byte stream can be achieved through a union. The characteristic of a union is that all its members share the same memory space. Therefore, different data types can be overwritten and written, and then the original bytes in the memory can be read in the form of a character array.

[0036] For example: typedef union { int integer; / / 4-byte integer (assuming sizeof(int) = 4) float floating; / / 4-byte floating-point number char bytes[4]; / / Character array for accessing the original bytes } DataConverter;

[0037] Above, we can assign any data type (of course, it can also be a structure), but during transmission and interaction, it is all carried out through bytes[4] (the size of the array is defined according to the largest data type in the union, and this is only an example here).

[0038] S300. Perform data filling according to the data length and data type, and encapsulate the packet structure according to the ID, data field length, and data content to obtain the encapsulated packets of each functional module.

[0039] After the encapsulated data is transmitted or exchanged, it can be restored through the definition of the encapsulation. Different applications can restore the actual meaning of the data through the definition of the encapsulation, which is convenient for data parsing between different customers.

[0040] In a preferred embodiment, such as Figure 3 , Figure 3 is Figure 1 a flowchart of a specific implementation manner of S300 in

[0041] The packet structure of the basic information functional module is shown in Table 5.

[0042] Table 5 Packet Structure of the Basic Information Functional Module As shown in Table 5, for the detailed functions in the sub-function information VehicleType, bit 0x01 of the 5th byte in the function data indicates the type is an electric bicycle, and bit 0x02 indicates the type is an electric motorcycle.

[0043] Using the Python language, the data of the basic information module is packaged. The program example is as follows: # Assume vehicle information: VehicleID = 0x12345678 VehicleType = 0x01 ProductionDate = 1654041600 # 2022-06-01 00:00:00 SoftwareVersion = 0x0201 # v2.1 HardwareVersion = 0x0100 # v1.0 # Convert to byte stream: data = bytes( 0x00, 0x01, # ID = 0x0001 0x0D, # Length = 13 0x12, 0x34, 0x56, 0x78, # VehicleID 0x01, # VehicleType 0x62, 0x8E, 0x80, 0x00, # ProductionDate (Unix timestamp) 0x02, 0x01, # SoftwareVersion 0x01, 0x00 # HardwareVersion )。

[0044] In a preferred embodiment, as Figure 4 , Figure 4 is Figure 3 a flowchart of a specific implementation after S330 in ; S300 further includes:

[0045] The data packets of each function module are encapsulated according to the following structure, as shown in Table 6, to achieve self-description.

[0046] Table 6 Unified encapsulation structure of each functional module S400. Cloud-store the encapsulated data packets of all functional modules to obtain a functional database, and share the functional database in the cloud control system of the two-wheeled electric vehicle for calling during development.

[0047] Preferably, as Figure 5 , Figure 5 is a flowchart of another embodiment of a data processing method for a two-wheeled electric vehicle in this application; the data processing method further includes: S500. Parse the encapsulated data packets at the application layer; S600. Sequentially read the ID information of the first two bytes, the length information of the third byte, and the basic data information of the subsequent bytes.

[0048] Preferably, as Figure 6 , Figure 6 is a flowchart of yet another embodiment of a data processing method for a two-wheeled electric vehicle in this application; the data processing method further includes: S700. Expand the control system, allocate an ID for the new functional module, and define the data packet structure of the new functional module; S800. Perform compatibility processing on the control system, and ignore the unknown ID when the old system is compatible with the new system, and discard the corresponding data information.

[0049] Since the system parses data through the ID, when the new system expands its functions, it will not affect the parsing of the old system because we only expand the ID and do not affect the original ID. Therefore, the new and old systems can coexist. Only the newly expanded functions will be discarded, but it can still be used normally without the system crashing or becoming unusable due to compatibility issues.

[0050] When new functional modules need to be added, only need to allocate new IDs and define the structure to achieve it. The old system can also be designed for compatibility. When designing the compatibility of the old system, the unknown IDs can be ignored and the data of the unknown IDs can be discarded.

[0051] By classifying the functions of the two-wheeled electric vehicle modularly, subdividing the sub-function information of each functional module, and defining and encapsulating the data packet structure of each functional module to obtain a functional database, the development process is simplified, and it is also convenient to expand functions and design for compatibility, improving the intelligent level of the two-wheeled electric vehicle.

[0052] In a second aspect, a cloud control system for a two-wheeled electric vehicle, as Figure 7 , Figure 7It is a schematic diagram of the module structure of the data processing module 900 in a cloud control system for a two-wheeled electric vehicle of the present application. The cloud control system includes a data processing module 900, and the data processing module 900 includes: A subdivision unit 901, which is used to classify the functions of the two-wheeled electric vehicle modularly, obtain a basic information module, a GPS function information module, a control function module, a lighting function information module, and a user-defined information module, and subdivide the sub-function information of each function module; A data packet structure definition unit 902, which is used to assign an ID to each function module, define the ID as the index byte of the data packet structure of the function module, define the data length and data type of each sub-function information in the function module, and define the union data of each sub-function information by using the ID; A data encapsulation unit 903, which is used to fill data according to the data length and data type, and encapsulate the data packet structure according to the ID, the data field length, and the data content to obtain an encapsulated data packet for each function module; A data sharing unit 904, which stores the encapsulated data packets of all function modules in the cloud to obtain a function database, and shares the function database in the cloud control system of the two-wheeled electric vehicle for calling during development.

[0053] Furthermore, the data processing module 900 further includes: A data parsing unit, which is used to parse the encapsulated data packet at the application layer, and sequentially read the ID information of the first two bytes, the length information of the third byte, and the basic data information of the subsequent bytes.

[0054] Furthermore, the data processing module further includes: A compatibility processing unit, which is used to perform compatibility processing on the control system, and ignore the unknown ID and discard the corresponding data information when the old system is compatible with the new system.

[0055] Furthermore, the data encapsulation unit is further used to: allocate a storage partition for each sub-function information, and in the storage partition, allocate a sub-storage partition for each subdivision function in the sub-function, and fill the data corresponding to the ID according to the sub-storage partition address.

[0056] Implementing a data processing method for a two-wheeled electric vehicle and its cloud control system of the present invention simplifies the development process by modularly classifying the functions of the two-wheeled electric vehicle, subdividing the sub-function information of each function module, and defining and encapsulating the data packet structure of each function module to obtain a function database, and also facilitates the expansion and compatibility design of functions, improving the intelligent level of the two-wheeled electric vehicle.
