Embodiment 1

[0044] See figure 1 The embodiment of the present invention provides a method for data transmission in a communication network. The communication network can refer to the communication network between the hardware modules, between the software modules, and between the hardware modules and the software modules in the unmanned vehicle system. The hardware module can be regarded as a terminal device with a processor, and the software module can be regarded as It is a program process running in the processor. Then, the port for data transmission and data communication in the communication network is the communication object or communication node, and the communication node may include multiple communication objects. The communication object or communication node is loaded and run by the program process. During the loading process, the attribute information of the communication object or communication node is initialized according to the program setting. Specifically, the communica...

Embodiment 2

[0059] Such as Figure 4 As shown, an embodiment of the present invention is a schematic flowchart of another embodiment of a communication network data transmission method. This embodiment is based on the first embodiment and adds the following steps:

[0060] S30: Broadcast the topology information to other processes in the communication network to update the topology record tables of other processes. Specifically, the process that receives the topology information records the received topology information in the topology record table of the process.

[0061] In the embodiment of the present invention, the topology information recorded in the topology record table may be broadcast to other processes in the communication network when or after the topology information is recorded in the topology record table. In another embodiment, the topology record table in this process can also be broadcast to other processes. After receiving the topology information, the other processes compar...

Embodiment 3

[0064] Such as Figure 5 As shown, the flow chart of another embodiment of the communication network data transmission method provided by the embodiment of the present invention; based on the second embodiment of the present example, the following steps S40 and S50 can be added:

[0065] S40. Receive topology information of the other process from the other process.

[0066] S50. Record the received topology information of the other processes in the topology record table.

[0067] In addition to broadcasting topology information to other processes, this process can also receive topology information broadcast or sent by other processes, and then record the received topology information in the topology record table of this process, so that each process of the entire communication network belongs to The information in the topology record table is synchronized to ensure the establishment of communication links. And after step S50 is executed, the current process based on the update of th...

Abstract

The invention provides a method for communication network data transmission, an apparatus for communication network data transmission, a storage medium and a terminal device for realizing communication network data transmission, wherein the method comprises the following steps: in response to loading of a first communication object in a communication network, recording topology information of thefirst communication object in a topology record table, wherein the topology record table is corresponding to a process which the first communication object belongs to, and is used for recording the topology information of the process which the first communication object belongs to, and recording the topology information received from the other processes of the communication network; and accordingto the topology record table, selecting a corresponding communication mode to establish a communication connection between the first communication object and a second communication object matched withthe first communication object. With the method, the apparatus, the storage medium and the terminal device provided by the invention, the corresponding communication mode can be selected for establishing a communication link between the communication objects in the communication network based on different topological relations.

Description

Technical field [0001] The present invention relates to the field of computer technology, and in particular to a method, device, storage medium and terminal equipment for data transmission in a communication network. Background technique [0002] Unmanned driving technology is the integration of multiple technologies. An unmanned driving system includes multiple sensors, multiple software modules and multiple hardware modules. The robot operating system ROS / ROS2 is introduced in the deployment of software and hardware resources as an unmanned driving system. The communication framework is a distributed multi-process framework based on message passing communication. Because ROS / ROS2 itself is based on the message mechanism, developers can split the software into modules (nodes) according to functions, and each module is only responsible for reading Retrieve and distribute messages, and the modules are associated through messages. [0003] However, the communication between modules ...
