Description

[0002] With the development of intelligent automobiles, vehicle-side communication technology has become increasingly important. The vehicle-side communication system needs to be able to support high-speed, real-time, and reliable data transmission to meet the needs of various in-vehicle applications. Among them, the distributed data distribution service (DDS) is an important communication protocol that makes data transmission between different nodes more efficient through a publish-subscribe mechanism. However, in the traditional DDS protocol, the sending and receiving IP addresses are related to the domain, which limits its application in vehicle-side communication to a certain extent. To solve this problem, some existing solutions are to achieve data sending and receiving by setting specific IPs. For example, a domain can set a receiving IP, and only one multicast IP can be set for sending. Although this method can achieve data transmission, due to the limitation of IP addresses, the efficiency of data transmission is not high, especially when the amount of data is large, network congestion may occur. Secondly, the existing solutions cannot achieve effective control of data transmission. For example, it is impossible to select a specific IP for data transmission according to user needs, and it is impossible to filter unnecessary data. These problems limit the application of existing solutions in vehicle-side communication. Summary of the invention

[0028] Exemplary Methods

[0029] Figure 1 is a flow chart of a method for implementing a distributed vehicle-side communication system according to an exemplary embodiment. Figure 1 As shown, the implementation method of the distributed vehicle-side communication system is used in application fields such as vehicle-side communication, intelligent driving, and automatic driving, and includes the following steps.

[0030] In step S110, based on the standard DDS protocol, a domain is configured with multiple IP addresses corresponding to unicast and multicast, wherein the multiple IP addresses are used for sending and receiving data;

[0031] Specifically, in the embodiment of the present invention, based on the standard DDS protocol, the sending and receiving IP addresses are reconfigured so that they are no longer limited to domain-related, but multiple IP addresses can be configured at the same time. In this way, whether it is unicast or multicast, a specific IP can be selected for data transmission according to user needs, thereby improving the efficiency of data transmission and avoiding network congestion.

[0032] In step S120, a communication matrix is ​​set based on the configured multiple IP addresses, wherein the communication matrix is ​​used to define the communication rules between the multiple IP addresses; in the embodiment of the present invention, the communication matrix is ​​designed and set in the system, and the user can preset which data needs to be sent or received from which IP according to their own needs. In this way, unnecessary data will be automatically ignored, thereby achieving precise control of data transmission.

[0033] In step S130, the publish-subscribe mechanism of the distributed communication protocol is adopted to perform data communication on the vehicle side based on the communication matrix. In the embodiment of the present invention, a pre-set Switch chip can be used to control the data communication on the vehicle side based on the communication matrix. Of course, other suitable chips can also be used to replace the Switch chip. By introducing the Switch chip into the system, the data transmission can be further precisely controlled through the communication filtering mechanism set therein, ensuring that only the required data can pass, thereby forming a complete and controllable communication system.

[0034] In step S130, in one example, data of a specific type may be sent or received from a corresponding IP address according to the correspondence between the data type and the IP address in the communication matrix set by the user, wherein the communication matrix specifically includes the correspondence between the data type and the IP address. In another example, data communication may be controlled according to the source address and the destination address in the communication matrix set by the user and the rule of whether bidirectional communication is possible, wherein the communication matrix specifically includes: the source address and the destination address and the rule of whether bidirectional communication is possible. In yet another embodiment, data communication may be allowed according to the data-specific conditions in the communication matrix set by the user, data whose data type meets the data-specific conditions.

[0035] It can be seen from the above processing that the embodiments of the present invention fully utilize the advantages of the distributed communication protocol DDS, such as the publish-subscribe mechanism, while avoiding the disadvantages brought by this distributed system, such as the impact of invalid multicast data on computing resources, thereby forming a set of efficient and reliable communication system suitable for the vehicle side.

[0036] With the development of automobile intelligence, vehicle-side communication technology has become increasingly important. The technical solution of the embodiment of the present invention can greatly improve the efficiency and reliability of vehicle-side communication and meet the needs of various vehicle-mounted applications. Especially in the case of large amounts of data, the technical solution of the embodiment of the present invention can effectively avoid the problem of network congestion and ensure real-time transmission of data. In addition, the embodiment of the present invention can also achieve effective control of data transmission, select a specific IP for data transmission according to user needs, and filter unnecessary data, thereby improving the pertinence and effectiveness of data transmission.

[0037] The above technical solution of the embodiment of the present invention is described in detail below with examples.

[0038] Step 1: Configure multiple IP addresses on the DDS protocol. Reconfigure the sending and receiving IP addresses. Specifically, the embodiment of the present invention can configure two IP addresses, namely IP1 and IP2. Both IP addresses can be used for sending and receiving data. In this way, whether it is unicast or multicast, a specific IP can be selected for data transmission according to user needs.

[0039] Step 2: Communication matrix setting Design and set the communication matrix in the system. Specifically, the embodiment of the present invention can create a 2*2 communication matrix, in which each row represents an IP address and each column represents a data type. For example, the first row and the first column represent IP1 and data type A, the first row and the second column represent IP1 and data type B, the second row and the first column represent IP2 and data type C, and the second row and the second column represent IP2 and data type D. In this way, users can preset which data needs to be sent or received from which IP according to their needs. For another example: the first column of the table represents the source addr, the second column represents the destination addr, and the third column represents whether it is unidirectional. The first column sets the local address to 1, the second column sets the destination address to 2 and 3, and the third column is set to yes, which means that the data sent by data 1 can reach 2 and 3, but the data from 2 and 3 cannot reach 1;

[0040] Step 3: Introduce a Switch chip into the system, and through the communication filtering mechanism set by it, the data transmission can be further precisely controlled. Specifically, the embodiment of the present invention can set a filtering rule, that is, only data that meets specific conditions can pass. For example, we only allow data of data type A and data type C to pass, while data of data type B and data type D will be automatically ignored.

[0041] The embodiment of the present invention utilizes the DDS distributed communication protocol publish-subscribe mechanism to efficiently and quickly distribute data to each distributed node. And by adjusting the communication matrix and filtering rules, only the required data can pass, thus forming an efficient and reliable communication system suitable for the vehicle side. At the same time, it avoids being affected by the shortcomings of this distributed system (such as invalid multicast data impacting computing resources and other issues).

[0042] The beneficial effects of the embodiments of the present invention are as follows:

[0043] The above technical solution of the embodiment of the present invention solves the problem of low data transmission efficiency caused by IP address restrictions, especially when the amount of data is large, network congestion may occur; at the same time, it solves the problem of not being able to select a specific IP for data transmission according to user needs; it also solves the technical problem of not being able to filter unnecessary data.

[0044] The technical solution of the embodiment of the present invention can improve the efficiency of data transmission: the embodiment of the present invention allows the configuration of multiple IP addresses (unicast and multicast) for the writer and reader of DDS, and can send or receive data through a specific IP according to user needs, thereby improving the efficiency of data transmission, especially when the amount of data is large, and can effectively avoid the problem of network congestion.

[0045] The embodiment of the present invention can achieve effective control of data transmission: In the embodiment of the present invention, the user can set up the communication matrix in advance, so that different data can be sent or received from different IPs according to needs, and unnecessary data will be ignored. This can achieve effective control of data transmission and meet the personalized needs of users.

[0046] The embodiment of the present invention forms a complete and controllable communication system: The embodiment of the present invention combines the advantages of distributed communication protocols such as DDS (publish-subscribe mechanism, etc.), but will not be affected by the disadvantages of such distributed systems (such as invalid multicast data impacting computing resources). It forms an efficient and reliable communication system suitable for the vehicle side, which has high practical value.

[0047] The embodiments of the present invention adapt to the complex communication needs of the vehicle side: Compared with the existing technology, the communication system of the embodiments of the present invention is more flexible and adaptable, and can better meet the complex communication needs of the vehicle side, which is of great significance for promoting the development of intelligent automobiles.

[0048] The technical solution of the embodiment of the present invention can greatly improve the efficiency and reliability of vehicle-side communication and meet the needs of various vehicle-mounted applications. Especially in the case of large amounts of data, the embodiment of the present invention can ensure real-time data transmission, and can also achieve effective control of data transmission, select a specific IP for data transmission according to user needs, and can also filter unnecessary data, thereby improving the pertinence and effectiveness of data transmission. The embodiment of the present invention has broad market demand and good application prospects.
