Detailed ways

Embodiments of the present invention solve the technical problem of how to accurately locate abnormal nodes in a communication network by providing a network diagnosis method and device oriented to a central computing and regional collaborative control architecture.

In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the network diagnosis method for central computing and regional cooperative control architecture in this embodiment includes:

Step S1, after the target message transmitted by the communication link is lost, obtain the fault information reported by the current network node on the communication link, the fault information includes the target message ID and the name of the network node sending the target message to the current network node ; The fault information is reported by the network nodes on the communication link when the target message transmitted by the communication link is lost;

Step S2, according to the network node name in the fault information, determine the last network node that sends the target message to the current network node;

Step S3, taking the previous network node as the current network node and judging whether the fault information reported by the current network node is received; if the fault information reported by the current network node is received, then jump to step S2; if the fault information reported by the current network node is not received If the fault information is reported, it is determined that the current network node is abnormal.

In this embodiment, the network diagnosis method for the central computing and regional cooperative control architecture is applied to the communication network of the central computing and regional cooperative control architecture shown in FIG. 2 as an example for illustration. The communication network in Figure 2 includes a central computing platform and multiple regional controllers, the central computing platform communicates with multiple regional controllers, and each regional controller also communicates with multiple ECUs (Electronic Control Units, electronic control units) connection, the central computing platform, each regional controller and each ECU are network nodes, the central computing platform and each regional controller also serve as a gateway to route messages, and each receiving network node sends the target message sent by the network node When the message is lost, the fault information will be reported. The fault information includes the target message ID and the name of the sending network node that sent the target message to the receiving network node. The loss of the target message in the communication network means that a certain link on the communication link that transmits the target message A network node is abnormal.

The longest communication link in FIG. 2 is shown in FIG. 3 . The message transmitted by the communication link in FIG. 3 has been routed by the gateway, so the target message is a routed message. Assuming that the target message is transmitted from ECU A-1 to ECU B-1, and the target message is lost at the network node regional controller A, the network node central computing platform, regional controller B and ECU B-1 will all report fault information , the fault information reported by the central computing platform includes the target message ID and the name of the regional controller A, the fault information reported by the regional controller B includes the target message ID and the name of the central computing platform, and the fault information reported by ECU B-1 includes Destination message ID and name of zone controller B. The current network node in step S1 is one of all network nodes that have reported fault information. Assuming that the current network node in step S1 is the regional controller B, then step S1 can obtain the name of the central computing platform, and then step S2 can determine the destination message to the regional controller B according to the name of the central computing platform in the fault information The last network node is the central computing platform; since the central computing platform also reported the fault information, step S3 will judge that the fault information reported by the central computing platform is received, which means that the target message is not lost at the node of the central computing platform, and jump to Turning to step S2, the fault information reported by the central computing platform includes the name of the regional controller A, and then step S2 can determine that the last network node that sent the target message to the central computing platform is the region according to the name of the regional controller A in the fault information Controller A; since the regional controller A has not reported the fault information, step S3 will judge that the fault information reported by the regional controller A has not been received, which means that the target message is lost at the node of the regional controller A, and determine the regional control Device A is abnormal.

In this embodiment, if the message is transmitted from ECU A-1 to ECU A-2 in FIG. 2 , the message is a non-routing message, ECU A-1 is the sending network node, and ECU A-2 is the receiving network node. After the message transmitted by the communication link is lost, this embodiment will obtain the fault information reported by ECU A-2. The fault information of the non-routing message only includes the name of ECU A-1, and then it can be directly determined that the message is in ECU A-2. If the node 1 is lost, it is determined that ECU A-1 is abnormal. The fault diagnosis method after the loss of non-routing packets is relatively simple. The network diagnosis method for the central computing and regional collaborative control architecture in Figure 1 is only for non-routing packets.

It can be seen from the above that after the target message transmitted by the communication link is lost in this embodiment, the network nodes that have not reported the fault information on the communication link will be traced forward step by step, so as to determine the abnormal network node and accurately locate the communication link. Unusual nodes of the network.

The target message in this embodiment can be any message, but the loss of a non-critical message can only indicate that a certain network node has a problem when delivering the message, and there is a high probability that the network node can still deliver other messages normally. Therefore, it is unnecessary to locate abnormal network nodes when non-critical packets are lost. And when a key message is lost, it can basically be determined that the network node that lost the key message is in a disconnected state and cannot transmit other messages. At this time, it is necessary to locate the network node that lost the key message. Therefore, in this embodiment, the target message is preferably a key message, and the abnormal network node will be located only after the key message is lost, so as to avoid meaningless fault diagnosis. Key messages include messages with attributes related to information security and functional safety, messages with the highest ID priority, and messages with the smallest period. Target messages can include messages with attributes related to information security and functional safety, messages with the highest ID priority, and periodic messages. Any one, two or three of the smallest packets. Messages related to information security and functional safety attributes include messages triggered by remote control devices and generated and issued by the vehicle-mounted terminal MCU, messages periodically sent by the vehicle-mounted terminal to the vehicle, target components (connected with the vehicle-mounted terminal) The ECU of the opposite end communication) sends the message to the vehicle terminal, the periodic communication message between the target components, or the message packaged by the gateway and then forwarded to the vehicle terminal. The message with the highest ID priority is the message that the network node will process first. It is difficult for such a message to be lost. Therefore, when such a message is lost, there is a high probability that a certain network node is offline. The message with the smallest period is the message with the highest sending frequency. Since this type of message is continuously transmitted, it is difficult to be lost. Therefore, when this type of message is lost, there is a high probability that a certain network node is offline. When the target message includes information security and functional safety-related attribute messages, the message with the highest ID priority and the message with the smallest period, when all the three key messages are lost, a certain network node can be determined to the greatest extent Disconnection can avoid meaningless fault diagnosis to the greatest extent. However, if there is no ECU with information security and functional safety attributes in the communication network, the target message may include any one or both of the message with the highest ID priority and the message with the smallest period.

In addition, the fault information in this embodiment may also include the target packet loss time, so that the time when the abnormal network node appears abnormal can be determined.

As shown in Figure 4, this embodiment also provides a network diagnostic device for central computing and regional collaborative control architecture, including:

The obtaining module is used to obtain the fault information reported by the current network node on the communication link after the target message transmitted by the communication link is lost. The fault information includes the target message ID and the network sending the target message to the current network node node name;

A determination module, configured to determine the last network node that sends the target message to the current network node according to the network node name in the fault information;

The judging module is used to use the previous network node as the current network node and judge whether the fault information reported by the current network node is received; if the fault information reported by the current network node is received, then jump to the network node name according to the fault information The step of determining the last network node that sends the target message to the current network node; if the fault information reported by the current network node is not received, it is determined that the current network node is abnormal.

This embodiment is described by taking the application of the network diagnosis device for the central computing and regional cooperative control architecture to the communication network of the central computing and regional cooperative control architecture shown in FIG. 2 as an example. The communication network in Figure 2 includes a central computing platform and multiple regional controllers, the central computing platform communicates with multiple regional controllers, and each regional controller also communicates with multiple ECUs (Electronic Control Units, electronic control units) connection, the central computing platform, each regional controller and each ECU are network nodes, the central computing platform and each regional controller also serve as a gateway to route messages, and each receiving network node sends the target message sent by the network node When the message is lost, the fault information will be reported. The fault information includes the target message ID and the name of the sending network node that sent the target message to the receiving network node. The loss of the target message in the communication network means that a certain link on the communication link that transmits the target message A network node is abnormal.

The longest communication link in FIG. 2 is shown in FIG. 3 . The message transmitted by the communication link in FIG. 3 has been routed by the gateway, so the target message is a routed message. Assuming that the target message is transmitted from ECU A-1 to ECU B-1, and the target message is lost at the network node regional controller A, the network node central computing platform, regional controller B and ECU B-1 will all report fault information , the fault information reported by the central computing platform includes the target message ID and the name of the regional controller A, the fault information reported by the regional controller B includes the target message ID and the name of the central computing platform, and the fault information reported by ECU B-1 includes Destination message ID and name of zone controller B. The current network node whose fault information is obtained by the obtaining module is one of all network nodes that have reported the fault information. Assuming that the current network node where the acquired module obtains the fault information is the regional controller B, the obtaining module can obtain the name of the central computing platform, and then the determining module can determine the target to send to the regional controller B according to the name of the central computing platform in the fault information. The last network node of the message is the central computing platform; since the central computing platform also reported the fault information, it means that the target message was not lost at the node of the central computing platform, so the judgment module will judge that the fault reported by the central computing platform is received Information, the fault information reported by the central computing platform includes the name of the regional controller A, and then the determination module can determine that the last network node that sent the target message to the central computing platform is the regional controller A according to the name of the regional controller A in the fault information ;Because the regional controller A did not report the fault information, the judging module will judge that the fault information reported by the regional controller A has not been received, which means that the target message is lost at the node of the regional controller A, and it is determined that the regional controller A is abnormal .

In this embodiment, if the message is transmitted from ECU A-1 to ECU A-2 in FIG. 2 , the message is a non-routing message, ECU A-1 is the sending network node, and ECU A-2 is the receiving network node. After the message transmitted by the communication link is lost, this embodiment will obtain the fault information reported by ECU A-2. The fault information of the non-routing message only includes the name of ECU A-1, and then it can be directly determined that the message is in ECU A-2. If the node 1 is lost, it is determined that ECU A-1 is abnormal. The fault diagnosis method after the non-routing message is lost is relatively simple. The network diagnosis device for the central computing and regional collaborative control architecture in Figure 4 is only for the non-routing message.

It can be seen from the above that after the target message transmitted by the communication link is lost in this embodiment, the network nodes that have not reported the fault information on the communication link will be traced forward step by step, so as to determine the abnormal network node and accurately locate the communication link. Unusual nodes of the network.

The target message in this embodiment can be any message, but the loss of a non-critical message can only indicate that a certain network node has a problem when delivering the message, and there is a high probability that the network node can still deliver other messages normally. Therefore, it is unnecessary to locate abnormal network nodes when non-critical packets are lost. And when a key message is lost, it can basically be determined that the network node that lost the key message is in a disconnected state and cannot transmit other messages. At this time, it is necessary to locate the network node that lost the key message. Therefore, in this embodiment, the target message is preferably a key message, and the abnormal network node will be located only after the key message is lost, so as to avoid meaningless fault diagnosis. Key messages include messages with attributes related to information security and functional safety, messages with the highest ID priority, and messages with the smallest period. Target messages can include messages with attributes related to information security and functional safety, messages with the highest ID priority, and periodic messages. Any one, two or three of the smallest packets. Messages related to information security and functional safety attributes include messages triggered by remote control devices and generated and issued by the vehicle-mounted terminal MCU, messages periodically sent by the vehicle-mounted terminal to the vehicle, target components (connected with the vehicle-mounted terminal) The ECU of the opposite end communication) sends the message to the vehicle terminal, the periodic communication message between the target components, or the message packaged by the gateway and then forwarded to the vehicle terminal. The message with the highest ID priority is the message that the network node will process first. It is difficult for such a message to be lost.
