Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data forwarding table generation method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 and the server 104 communicate over a network. In the application, a data forwarding table to be processed and update information of access equipment CAN be acquired through a server 104, and the data forwarding table to be processed is updated according to the update information. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a method for generating a data forwarding table is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:
At present, vehicle data is mainly communicated based on a CAN network, but because the network communication ID and network equipment are statically configured during CAN communication, when new equipment is accessed to the CAN network, the ID configuration cannot be updated in real time according to changed IDs for communication, but the CAN gateway needs to be upgraded to identify the IDs, which is not beneficial to data forwarding communication.
In step 201, it is exemplarily illustrated that a data forwarding table to be processed and update information of an access device are obtained, and the data forwarding table to be processed is updated according to the update information, for example, a corresponding data forwarding table may be generated according to a newly accessed CAN device, and the data forwarding table includes a corresponding relationship between a network identifier to be received and a physical identifier to be received, so that when data needs to be sent, a to-be-sent end sends the network identifier to be received to a CAN gateway, and the CAN gateway finds the physical identifier to be received corresponding to the network identifier to be received from the data forwarding table. In some implementation processes, when a CAN device sends a request CAN ID, that is, a network identifier to be received, and a CAN gateway receives the network identifier to be received, corresponding information and a physical identifier to be received are searched in a corresponding data forwarding table, another CAN device in communication with the CAN device CAN be obtained through the physical identifier to be received and the network identifier to be received, and the another CAN device generates a CAN ID for response, that is, a network identifier to be sent, and similarly, the CAN gateway searches information corresponding to the network identifier to be sent in the data forwarding table, and sends data to the CAN device for communication through the searched corresponding information, for example, as shown in fig. 4, an ECUA1 first sends 0x2A to the CAN gateway, and after receiving 0x2A, the CAN gateway finds that the data should be sent to a CAN forwarding table port 2 by searching the CAN network; ECUB1 generates a response CAN ID of 0x1A after receiving the CAN ID of 0x2A, sends the CAN ID of 0x1A to the CAN gateway, the CAN gateway searches a network forwarding table after receiving 0x1A and finds that 0x1A is to be sent to CAN port 1, and CAN port 1 establishes communication with CAN port 2 after receiving 0x1A and forwards the data to CAN port 2 through the CAN gateway. Similarly, the corresponding data can be forwarded to each domain according to the data forwarding table by the method.
As a specific implementation manner of the foregoing embodiment, acquiring a data forwarding table to be processed and update information of an access device, and updating the data forwarding table to be processed according to the update information includes: acquiring a data frame of access equipment, and acquiring updating information of the access equipment according to the data frame, wherein the updating information comprises a corresponding relation between a network identifier to be received and a physical identifier to be received; and updating the data forwarding table to be processed according to the corresponding relation.
It should be noted that the data frame may be a broadcast frame in a CAN network. For example, when a new CAN device is accessed to the CAN gateway, the CAN device may allow the CAN gateway to obtain the network identifier to be received in the form of a broadcast frame of the CAN network, and the CAN gateway may record the corresponding physical identifier to be received through the network identifier to be received, and generate a data forwarding table of the corresponding relationship between the network identifier to be received and the physical identifier to be received. Further, in order to improve the flexibility of updating the CAN ID, a corresponding data forwarding table may be generated by including more configuration information in the data frame, as shown in fig. 3, the data forwarding table may include information such as access time of the CAN device, whether it is aged, whether it supports cross-domain forwarding, whether it is statically configured, and aging time, where whether it is aged to solve whether the corresponding relationship between the CAN device and the CAN ID is deleted under the condition that the access CAN device has dropped; whether cross-domain solution CAN gateway is supported or not is judged whether corresponding CAN ID receiving is opened or not; whether static configuration is supported or not is judged to solve the forwarding requirement whether the CAN ID supports the fixed CAN ID or not; the aging time is the time for updating the corresponding data forwarding table of the CAN equipment, the CAN gateway needs to be notified of the relevant updated access time when the CAN equipment is accessed or at regular time, and if the aging time is reached, the notification is not carried out yet, so that the equipment is marked to be disconnected and does not need to be recorded. In addition, after the CAN gateway receives the data frame, all ports after the port that receives the data frame need to be excluded from forwarding, so that the lower-level CAN gateway CAN record the corresponding CAN ID.
As a specific implementation manner of the foregoing embodiment, updating a data forwarding table to be processed according to a corresponding relationship includes: acquiring configuration information of the access equipment according to the updating information; and judging whether the configuration information is static configuration, and if not, updating the data forwarding table to be processed according to the corresponding relation.
It should be noted that, further, in order to improve the flexibility of updating the CAN ID, more configuration information may be generated through the data frame, as shown in fig. 3, the configuration information may include information such as access time of the CAN device, whether it is aged, whether it supports cross-domain forwarding, whether it is statically configured, and aging time, where whether it is aged to solve whether the corresponding relationship between the CAN device and the CAN ID is deleted under the condition that the access CAN device has been disconnected; whether the cross-domain solution CAN gateway is supported or not is judged whether the corresponding CAN ID is opened or not; whether static configuration is supported or not is judged to solve the forwarding requirement whether the CAN ID supports the fixed CAN ID or not; the aging time is the time for updating the corresponding data forwarding table of the CAN equipment, the CAN gateway needs to be notified of the relevant updated access time when the CAN equipment is accessed or at regular time, and if the aging time is reached, the notification is not carried out yet, so that the equipment is marked to be disconnected and does not need to be recorded. The data forwarding table may include whether the network identifier is statically configured, which determines whether the data forwarding method in the present application is compatible with the previous method for fixedly configuring the CAN ID, and if the data forwarding method is statically configured, the corresponding relationship of the CAN ID of the CAN device does not change, so that the data forwarding table does not need to be updated in real time, but if the data forwarding table is dynamically configured, the data forwarding table corresponding to the CAN device needs to be updated.
As a specific implementation manner of the foregoing embodiment, after obtaining the configuration information of the access device according to the update information, the method further includes: judging whether the configuration information supports aging; if not, acquiring an off-line signal of the access equipment, and deleting the corresponding relation according to the off-line signal.
It should be noted that, further, in order to improve flexibility of updating the CAN ID, a corresponding data forwarding table may be generated by including more configuration information in the data frame, as shown in fig. 3, the data forwarding table may include information such as access time of the CAN device, whether it is aged, whether it supports cross-domain forwarding, whether it is statically configured, and aging time, where whether it is aged to solve whether it is the case that the access CAN device has dropped, the corresponding relationship between the CAN device and the CAN ID is deleted, and if it is supported, the corresponding relationship between the CAN device and the CAN ID is not deleted, and if it is not supported, the corresponding relationship between the CAN device and the CAN ID is deleted.
As a specific implementation manner of the foregoing embodiment, determining whether the configuration information is static configuration, and if not, updating the data forwarding table to be processed according to the corresponding relationship includes: judging whether the configuration information is static configuration, if not, obtaining a corresponding update time threshold according to the configuration information; and according to the update time threshold and the corresponding relation, periodically updating the data forwarding table to be processed.
It should be noted that configuration information, such as aging time, may be added through a data frame, where the aging time may be used as an update time threshold of a data forwarding table of a CAN device, when the CAN device is in a dynamic configuration, the data forwarding table including network identification information needs to be updated, and an update period may be based on the update time threshold, optionally, the aging time may be set to 5 minutes or 10 minutes, where no specific limitation is made here, and when the update time threshold is reached, an update aging time message is sent to update the data forwarding table.
In one embodiment, a data forwarding method is provided, comprising the steps of:
and forwarding the data by using the data forwarding table obtained by the data forwarding table generating method to obtain the data to be sent.
As a specific implementation manner of the foregoing embodiment, performing data forwarding includes: acquiring a network identifier to be received, and acquiring a corresponding physical identifier to be received from a data forwarding table according to the network identifier to be received; and acquiring data to be transmitted, and forwarding the data to be transmitted according to the physical identifier to be received.
The network identification refers to a CAN ID, the physical identification refers to a physical CAN port, namely the network identification to be received refers to a CAN ID of a terminal to be received, the physical identification to be received refers to a physical CAN port of the terminal to be received, the network identification to be sent refers to a CAN ID of a terminal to be sent, and the physical identification to be sent refers to a physical CAN port of the terminal to be sent.
As a specific implementation manner of the foregoing embodiment, acquiring data to be transmitted and forwarding the data to be transmitted according to a physical identifier to be received includes: acquiring data to be sent and a corresponding physical identifier to be sent, and comparing whether the identification in the house to be sent and the physical identifier to be received are the same or not; if not, forwarding the data to be transmitted according to the physical identification to be received.
It should be noted that, the data forwarding includes cross-domain forwarding and co-domain forwarding, whether the data forwarding is the cross-domain forwarding CAN be determined through a physical port where two pieces of CAN equipment performing communication are located, that is, when the physical identifier to be received is different from the physical identifier to be sent, the data forwarding is the cross-domain forwarding, and when the physical identifier to be received is different from the physical identifier to be sent, the data forwarding is the co-domain forwarding, and it is determined that the data forwarding belongs to the cross-domain forwarding or the co-domain forwarding, and accordingly, different data processing modes are provided. The data is forwarded after the corresponding information is searched in the data forwarding table through the CAN gateway.
As a specific implementation manner of the foregoing embodiment, acquiring data to be sent and a corresponding physical identifier to be sent, and comparing whether the identifier in the room to be sent and the physical identifier to be received are the same, the method further includes: and if so, discarding the obtained data to be sent.
It should be noted that, when data is forwarded in the same domain, the data may not be forwarded through the CAN gateway, so that when the CAN gateway forwards the data in the same domain again, secondary reception occurs, which results in a situation of receiving repeated data, in order to avoid repeated reception of the data, it may be determined whether the data is forwarded in the same domain according to whether the physical identifier to be received and the physical identifier to be sent are the same, and when the data is forwarded in the same domain, the CAN gateway discards the received data to be sent, as shown in fig. 4, when the ECU _ A1 and the ECU _ B1 communicate with each other, the data is directly forwarded through the CAN gateway due to cross-domain forwarding, and when the ECU _ C1 and the ECU _ C3 communicate with each other, the data may be directly forwarded through the CAN bus, and therefore, when the CAN gateway finds that the physical ports of the ECU _ C1 and the ECU _ C3 are both CAN ports 3, the CAN gateway discards the data to be sent.
It should be understood that, although the steps in the flowchart of fig. 2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 2 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
