[0110] In order to make the ordinary person skilled in the art better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings.

[0111] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0112] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0113] See also Figure 1 , Figure 1 This is a flowchart of a message communication processing method according to an exemplary embodiment. Specifically, the method can be applied to a sending end, and the method may include the following steps:

[0114] Step S101: upon receiving a first original message content corresponding to any message to be sent, obtaining a first physical address of the first original message content.

[0115] In actual applications, the above-mentioned sending end can be a sending terminal of the message, such as a vehicle-mounted terminal, etc. The vehicle-mounted terminal may include a vehicle-mounted domain controller. Accordingly, the message communication processing method provided in the embodiment of the present application can be executed based on the vehicle-mounted domain controller.

[0116] In a specific embodiment, the first original message content corresponding to the message to be sent may be the first original message content corresponding to the message that the vehicle-mounted domain controller needs to send. In a specific embodiment, the first original message content may be control data. Exemplarily, the control data may be unmanned driving environment perception data streams such as power control data, brake control data, and steering control data. Specifically, the power control data may be engine speed and accelerator pedal position. The brake control data may be brake pedal position and brake pressure. The steering control data may be steering wheel data and steering torque. In a specific embodiment, the first original message content may be perception data. Exemplarily, the perception data may be millimeter wave radar data and lidar data.

[0117] In a specific embodiment, the message to be sent is a third encapsulated message, such as Figure 2 As shown, the above method also includes:

[0118] Step S201, encapsulating the first original message content based on a real-time publishing and subscribing protocol at an application layer to obtain a first encapsulated message.

[0119] In one specific embodiment, the first encapsulated message includes a message header of the real-time publishing and subscribing protocol and the first original message content. The message header of the real-time publishing and subscribing protocol contains basic information such as a protocol version, a message type, and a sequence number, and is used to identify and process the message.

[0120] Step S203, determining a second storage space from the first preset queue of the first preset memory based on third preset configuration information in a process of accessing the first preset memory based on the first preset original partition, and storing the first encapsulated message in the second storage space.

[0121] In one specific embodiment, the first preset original partition is used to allocate the first preset memory to the first preset queue rawpktQ (raw packet queue) and a preset sending queue. For example, the first preset original partition can be a RAW (raw device) on the sending end side. In one specific embodiment, the first preset memory includes the first preset queue and the preset sending queue, and the first preset memory is mapped based on mmap (Memory Mapping) so that the first preset original partition, the first user mode driver, and the first network card hardware can all access. In one specific embodiment, the third preset configuration information is a virtual address of the first preset queue in the first preset memory. In one specific embodiment, the first preset queue is used to store messages to be sent. In one specific embodiment, the second storage space is any idle storage space rawpktqe (raw packet queue element) in the first preset queue.

[0122] In one specific embodiment, the process of determining the second storage space from the first preset queue of the first preset memory based on the third preset configuration information in the process of accessing the first preset memory based on the first preset original partition, and storing the first encapsulated message in the second storage space can be that, based on the virtual address of the first preset queue in the first preset memory, the first preset original partition can access the first preset queue in the first preset memory, find the idle second storage space in the first preset queue, and store the first encapsulated message in the second storage space.

[0123] Step S205, recording a first virtual address and a first memory address of the first encapsulated message in the second storage space.

[0124] In a specific embodiment, the first virtual information may be an address assigned by the operating system to the current message communication process. The first virtual information includes a page directory index, a page table index, and an offset within the page. In a specific embodiment, the page directory index is used to find an entry in the page directory, the page table index is used to find an entry in the page table, and the offset within the page is used to locate data within the page.

[0125] Step S207: Based on the User Datagram Protocol at the transport layer, the first encapsulated message is encapsulated in the second storage space to obtain a second encapsulated message.

[0126] In one specific embodiment, the second encapsulated message includes User Datagram Protocol (UDP) port information, a Real-Time Publish Subscribe (RTPS) header, and the first original message content. In one specific embodiment, the UDP port information is used to identify a specific application or service in the network, and each UDP port information is associated with a specific application or service. The UDP port information can be used to determine to which application or service the first encapsulated message should be delivered.

[0127] Step S209 : Based on the Internet protocol at the network layer, the second encapsulated message is encapsulated in the second storage space to obtain a third encapsulated message.

[0128] In one specific embodiment, the third encapsulated message includes an Internet Protocol (IP) address, User Datagram Protocol (UDP) port information, a Real-Time Publish Subscribe (RTPS) message header, and the first original message content. In one specific embodiment, the IP address is used to uniquely identify and locate each device on the Internet or a local area network (LAN). Using the IP address, the second encapsulated message can be correctly routed to the target device.

[0129] In the above embodiment, the flexibility and efficiency of message transmission are improved through the layered encapsulation process. Application layer encapsulation ensures that the message format complies with the protocol requirements, and further encapsulation at the transport layer and network layer ensures that the message is transmitted safely and reliably in the network. Based on the virtual address of the first preset queue in the first preset memory, the first preset original partition can directly access the first preset queue and determine the second storage space, which helps to efficiently store the messages to be sent, thereby improving the utilization rate of the first preset memory and the flexibility of processing the messages to be sent, ensuring the reasonable allocation and efficient access of the first preset memory resources, and improving the integrity and performance of the transmission of the messages to be sent.

[0130] In a specific embodiment, obtaining the first physical address of the first original message content includes:

[0131] The first virtual address is converted into a first physical address.

[0132] In a specific embodiment, the conversion of the first virtual address into the first physical address may include first obtaining a base address of a page table from a page directory using a page directory index of the first virtual address. Next, obtaining a base address of a page frame from a page table using the page table index of the first virtual address. Finally, combining the page frame base address with the page offset of the first virtual address to calculate the final first physical address.

[0133] In the above embodiment, by converting the first virtual address into the first physical address, it is ensured that the actual first preset memory can be correctly accessed and operated. This conversion enables the first network card hardware to read the message to be sent from the first preset memory so as to correctly send the message to be sent, ensure that the content of the message to be sent is consistent with the actual message in the memory, and improve the accuracy and reliability of message transmission.

[0134] Step S103 , in the process of accessing the first preset memory based on the first user mode driver, based on the first preset configuration information, a first storage space is determined from the preset sending queue of the first preset memory, and the first physical address is stored in the first storage space.

[0135] In one specific embodiment, the first preset configuration information is a virtual address of a preset send queue in a first preset memory. In one specific embodiment, the preset send queue is a memory area that stores and manages basic information of received messages to be sent. In one specific embodiment, the first storage space is any free storage space in the preset send queue.

[0136] In a specific embodiment, in the above process of accessing the first preset memory based on the first user state driver, based on the first preset configuration information, the first storage space is determined from the preset sending queue of the first preset memory, and the first physical address is stored in the first storage space, which can be a virtual address based on the preset sending queue in the first preset memory. The first user state driver can access the preset sending queue in the first preset memory, search for the free first storage space in the preset sending queue, and place the first physical address in the first storage space, thereby changing the first storage space from an idle state to an occupied state.

[0137] Step S105, in the process of accessing the first preset memory based on the first network card hardware, when it is detected that any idle storage space in the preset sending queue is occupied, based on the second preset configuration information, the first storage space is taken out from the preset sending queue, the first storage space is parsed, and the first physical address is obtained.

[0138] In a specific embodiment, the second preset configuration information is the physical address of the preset sending queue in the first preset memory.

[0139] In a specific embodiment, in the above-mentioned process of accessing the first preset memory based on the first network card hardware, when it is detected that any free storage space in the preset sending queue is occupied, based on the second preset configuration information, the first storage space is taken out from the preset sending queue, and the first storage space is parsed to obtain the first physical address, which can be the physical address of the preset sending queue in the first preset memory. The first network card hardware can access the preset sending queue in the first preset memory. When it is detected that any free storage space in the preset sending queue is occupied, the occupied first storage space is taken out from the preset sending queue and parsed to obtain the first physical address.

[0140] Step S107: Send the message to be sent based on the first physical address and the first network card hardware.

[0141] In a specific embodiment, Figure 3 As shown, the sending of the message to be sent based on the first physical address and the first network card hardware includes:

[0142] Step S301 : in a process of accessing a first preset memory based on first network card hardware, obtaining a first memory address based on fourth preset configuration information and a first physical address.

[0143] In a specific embodiment, the fourth preset configuration information is the physical address of the first preset queue in the first preset memory.

[0144] In a specific embodiment, in the above process of accessing the first preset memory based on the first network card hardware, based on the fourth preset configuration information and the first physical address, obtaining the first memory address can be based on the physical address of the first preset queue in the first preset memory. The first network card hardware can access the first preset queue in the first preset memory, and based on the first physical address of the second storage space of the message to be sent in the first preset queue, obtain the first memory address of the second storage space of the first preset queue in the first preset queue.
