[0034] This embodiment proposes a data transmission method, so that the UDS solution can be well applied to scenarios of frequent data interaction between different processes. Combine below figure 2 and image 3 The data transmission method of this embodiment is described, figure 2 is a schematic flow chart of the data transmission method of this embodiment, image 3 It is a schematic diagram of the UDS-based double-buffering data transmission framework of the present embodiment, and the data transmission method of the present embodiment includes:
[0035] Step 201, after the server process establishes a socket connection with the client process, the server process cyclically calls the sending function to send data to the client process;
[0036]In this embodiment, the server (Server) process and the client (Client) process are different processes on the same electronic device, and a UDS communication mechanism is used between them. Optionally, in this embodiment, the se...

[0068] see Figure 4 , this embodiment provides a refined data transmission method, the method includes:
[0069] Step 401, after the server process establishes a socket connection with the client process, the server process cyclically calls the sending function to send data to the client process;
[0070] Step 402, the client process cyclically calls the receiving function to receive the data sent by the server process;
[0071] Step 403, the client process writes the received data into an unfilled sub-buffer in the target buffer, wherein the target buffer includes a first sub-buffer and a second sub-buffer;
[0072] Step 404, when the third-party process needs data, the third-party process reads data from the sub-buffer of the target buffer that stores data;
[0073] For the above steps 401-404, refer to steps 201-204 in the first embodiment, which will not be repeated here.
[0074]Step 405, if the third-party process and the client process concurrently read and write op...

[0102] see Figure 5 , this embodiment provides an electronic device, the electronic device includes:
[0103] The server module 501 is used to call the sending function to send data to the client module in a loop after establishing a socket connection with the client module;
[0104] The client module 502 is used to call the receiving function to cyclically receive the data sent by the server module, and write the received data into the unfilled sub-buffers in the target buffer, wherein the target buffer includes the first sub-buffer and the second sub-buffer. Second sub-buffer;
[0105] The third-party process module 503 is used to read data from the sub-buffer of the target buffer where data is stored when data is needed, wherein, if the third-party process module and the client module concurrently read and write operations to the target buffer , then the third-party process module and the client module respectively monopolize a sub-buffer in the target buffer, and the th...
