Description

Technical Field

[0001] This disclosure relates to the field of vehicle diagnostic technology, and in particular to a data synchronization method, apparatus, electronic device and storage medium. Background Technology

[0002] With the rapid development of intelligent driving, fault detection has become a core guarantee for driving safety. How to achieve efficient collaboration among multiple applications has also become the key to improving the real-time performance and accuracy of fault detection.

[0003] In related technologies, broadcast push is often used to push messages to multiple targets in fault detection scenarios. However, in related technologies, the broadcast method uses indiscriminate full push, and fault messages will be sent to irrelevant domains / applications at the same time, generating a large amount of redundant traffic, resulting in high bus load. Furthermore, it is impossible to accurately control the message transmission range and dynamically limit the broadcast boundary, resulting in low granularity and flexibility of communication, which in turn leads to instruction delays and reduced efficiency of fault detection.

[0032] In the embodiments described in this specification, the terminal 100 and the server 200 can be directly or indirectly connected through wired or wireless communication, and this disclosure does not impose any restrictions.

[0033] Figure 2 This is a flowchart illustrating a data synchronization method according to an exemplary embodiment, which is used in a server such as Figure 2 As shown, it includes the following steps.

[0034] In step S201, a detection synchronization message for the target application in the multi-application collaborative system is received, and a fault detection instruction is sent to the target application to enable the target application to perform fault detection and obtain fault detection data. In one specific embodiment, the multi-application collaborative system can be a system composed of multiple applications with collaborative relationships. The detection synchronization message can be used to indicate the synchronization of fault detection data. The multi-application collaborative system can include a target detection application domain and an application domain to be synchronized. The target detection application domain can be the application domain that needs to be detected for faults, as indicated by the detection synchronization message. Correspondingly, the application domain to be synchronized can be a domain that has a collaborative relationship with the target detection application domain.

[0035] In a specific embodiment, the target application can be the application that needs to perform fault detection as indicated by the detection synchronization message. The target application can be the application with the target address in the target detection application domain. The target address can be the application address carried by the detection synchronization message. Specifically, the target address can be the logical address of the application, such as 0x1233, 0x1234, 0x1235, etc.

[0036] In one specific embodiment, the detection synchronization message may include a message propagation flag, a cross-domain flag, and an application domain identifier to be synchronized. The message propagation flag can be used to indicate whether to direct the fault detection data to the application with the target address. The cross-domain flag can be used to indicate whether to send the fault detection data to the application domain to be synchronized. The application domain identifier to be synchronized may be a domain identifier carried in the detection synchronization message. The application domain identifier to be synchronized may be the representation information of the application domain to be synchronized. The application domain to be synchronized may include the application with the target address.

[0037] In a specific embodiment, the detection synchronization message can be 5A (frame header) 00 00 00 0E (data field length) F0 20 (control field) 02 (domain ID) 12 34 (destination address) 56 78 (source address) 00 00 00 01 (serial number) 01 23 45 (fault detection data) A1 B2 C3 D4 (CRC), such as... Figure 3 The frame structure diagram shown can be a VDCP (Video Disk Communications Protocol) frame structure. Accordingly, the message propagation flag can be Bit 15, the cross-domain flag can be Bit 13, the application domain identifier to be synchronized can be the domain ID, and the control field can be F0 20. Converting the control field to binary 1111 0000 0010 0000, the message propagation flag is 1, the cross-domain flag is 1, and the application domain identifier to be synchronized is 02. Accordingly, the detection synchronization message can instruct the fault detection data to be sent across domains to the application in application domain 02 to be synchronized.

[0038] In an optional embodiment, the detection synchronization message may further include an encryption flag, which can be used to indicate whether the detection synchronization message has been encrypted. The above-described receiving of the detection synchronization message for a target application in the multi-application collaborative system, sending a fault detection instruction to the target application to enable the target application to perform fault detection, and obtaining fault detection data includes: Receive detection synchronization messages for target applications in a multi-application collaborative system and obtain a preset key; Based on the preset key, the detection synchronization message is decrypted to obtain the decrypted detection synchronization message. Based on the decrypted detection synchronization message, a fault detection command is sent to the target application to enable the target application to perform fault detection and obtain fault detection data.

[0039] In one specific embodiment, a preset key can be used to decrypt the detection synchronization message. The preset key can be a key predetermined by the sender of the detection synchronization message, specifically, such as... Figure 4As shown, the encryption flag can be Bit 11. When Bit 11 is 1, the preset key is obtained to decrypt the detection synchronization message and obtain the decrypted detection synchronization message.

[0040] In the above embodiments, by encrypting the detection synchronization message and decrypting it based on a key predetermined by the sender of the detection synchronization message, the security of fault detection can be improved.

[0041] In an optional embodiment, after receiving the detection synchronization message for the target application in the multi-application collaborative system, sending a fault detection instruction to the target application to enable the target application to perform fault detection, and obtaining fault detection data, the above method may further include: The fault detection data is sent to the fault detection device so that the fault detection device can obtain the updated message propagation flag, the updated cross-domain flag, and the updated application domain identifier to be synchronized based on the fault detection data and the detection synchronization message update instruction triggered by the target account, and update the detection synchronization message.

[0042] In a specific embodiment, the fault detection device can be a terminal providing fault detection services. The detection synchronization message update instruction can be used to instruct the updating of the detection synchronization message. For example, the detection synchronization message can be 5A (frame header) 00 00 00 0E (data field length) F0 20 (control field) 02 (domain ID) 12 34 (destination address) 56 78 (source address) 00 00 00 01 (serial number) 01 23 45 (fault detection data) A1 B2 C3 D4 (CRC). Correspondingly, the message propagation flag (Bit 15) is 1, the cross-domain flag (Bit 13) is 1, and the domain identifier to be synchronized (domain ID) is 02. The detection synchronization message update instruction can be used to instruct the updating of the detection synchronization message by changing the message propagation flag (Bit 15) from 1 to 0 and the domain identifier to be synchronized (domain ID) from 02 to 03. Correspondingly, the updated detection synchronization message is 5A (frame header) 00 00 00 0E (Data Field Length) 7020 (Control Field) 03 (Domain ID) 12 34 (Destination Address) 56 78 (Source Address) 00 00 00 01 (Serial Number) 01 23 45 (Fault Detection Data) A1 B2 C3 D4 (CRC).

[0043] In the above embodiments, by updating the detection synchronization message through the update instruction triggered by the target account on the fault detection device, the user can flexibly configure the message transmission range and improve the granularity and flexibility of communication.

[0044] In step S203, the target synchronization application corresponding to the fault detection data is determined from the multi-application collaboration system based on the message propagation flag, cross-domain flag, target address and / or the domain identifier of the application to be synchronized. In one specific embodiment, the target synchronization application can be a collaborative application corresponding to the target application. Specifically, the fault detection data corresponding to the target application can be synchronized to the target synchronization application.

[0045] In an optional embodiment, the method of determining the target synchronization application corresponding to the fault detection data from the multi-application collaboration system based on the message propagation flag, cross-domain flag, target address, and / or the domain identifier of the application to be synchronized includes: When the message propagation flag indicates that the fault detection data is directed to the application with the target address, and the cross-domain flag indicates that the fault detection data is sent to the application domain to be synchronized, the application with the target address in the application domain to be synchronized is determined as the target synchronization application corresponding to the fault detection data based on the target address and the identifier of the application domain to be synchronized.

[0046] In a specific embodiment, taking the target detection application domain as 01 as an example, the detection synchronization message can be 5A (frame header) 00 00 00 0E (data field length) 38 00 (control field) 03 (domain ID) 12 34 (target address) 56 78 (source address) 00 00 00 01 (serial number) 01 23 45 (fault detection data) A1 B2 C3 D4 (CRC), such as... Figure 3 The frame structure diagram shown indicates that the control field can be 38 00. Converting the control field to binary 0011 10000000 0000, the message propagation flag is 0 and the cross-domain flag is 1. Accordingly, the detection synchronization message can instruct the fault detection data to be sent across domains to the application with address 0x1234 in application domain 03 to be synchronized.

[0047] In the above embodiments, by detecting the message propagation flag, cross-domain flag, and target address in the synchronization message, fault detection data can be synchronized to a specified application in a specified domain, thereby achieving accurate synchronization of fault detection data and reducing bus load.

[0048] In an optional embodiment, the method of determining the target synchronization application corresponding to the fault detection data from the multi-application collaboration system based on the message propagation flag, cross-domain flag, target address, and / or the domain identifier of the application to be synchronized includes: When the message propagation flag indicates that fault detection data should not be sent to the application with the target address, and the cross-domain flag indicates that fault detection data should not be sent to the application domain to be synchronized, the application other than the target application in the target detection application domain is determined as the target synchronization application corresponding to the fault detection data based on the target address.

[0049] In a specific embodiment, taking the target detection application domain as 01 as an example, the detection synchronization message can be 5A (frame header) 00 00 00 0E (data field length) 38 00 (control field) 03 (domain ID) 12 34 (target address) 56 78 (source address) 00 00 00 01 (serial number) 01 23 45 (fault detection data) A1 B2 C3 D4 (CRC), such as... Figure 3 The frame structure diagram shown indicates that the control field can be 38 00. Converting the control field to binary 1000 00000000 0000, the message propagation flag is 1, the cross-domain flag is 0, and the target address is 0x1234. Accordingly, the target application can be an application with address 0x1234 in the 01 domain.

[0050] In a specific embodiment, taking the target detection application domain as 01 as an example, the target detection application domain includes application addresses that can be 0x1233, 0x1234, 0x1235, and 0x1236. Specifically, 0x1233 can be the master, used to receive detection synchronization messages and send them to the target application 0x1234. 0x1234, 0x1235, and 0x1236 can be slaves. Correspondingly, as... Figure 4 As shown, the detection synchronization message can instruct fault detection data to be sent to applications in the 01 domain except for those with addresses 0x1235 and 0x1236.

[0051] In the above embodiments, by detecting the message propagation flag, cross-domain flag, and target address in the synchronization message, fault detection data can be synchronized to all applications in the target detection application domain, thereby improving the efficiency of fault detection data synchronization and reducing synchronization latency.

[0052] In an optional embodiment, the method of determining the target synchronization application corresponding to the fault detection data from the multi-application collaboration system based on the message propagation flag, cross-domain flag, target address, and / or the domain identifier of the application to be synchronized includes: When the message propagation flag indicates that the fault detection data should not be sent to the application with the target address, and the cross-domain flag indicates that the fault detection data should be sent to the application domain to be synchronized, the application in the application domain to be synchronized is determined as the target synchronization application corresponding to the fault detection data based on the application domain identifier.

[0053] In a specific embodiment, taking the target detection application domain as 01 as an example, the detection synchronization message can be 5A (frame header) 00 00 00 0E (data field length) 38 00 (control field) 04 (domain ID) 12 34 (target address) E8 00 (source address) 00 00 00 01 (serial number) 01 23 45 (fault detection data) A1 B2 C3 D4 (CRC), such as... Figure 3 The frame structure diagram shown indicates that the control field can be E8 00. Converting the control field to binary 1110 10000000 0000, the message propagation flag is 1, the cross-domain flag is 1, and the domain ID is 04. Correspondingly, the application domain to be synchronized can be domain 04. Optionally, the application to be synchronized includes the application's address. 0x1233 can be the master, used to receive fault detection data and send it to the application in domain 04. 0x1234 and 0x1235 can be slaves. Specifically, as shown... Figure 4 As shown, the detection synchronization message can instruct fault detection data to be sent to applications in the 04 domain with addresses 0x1233, 0x1234, and 0x1235.

[0054] In the above embodiments, by detecting the message propagation flag, cross-domain flag, and application domain identifier to be synchronized in the synchronization message, fault detection data can be synchronized across domains to all applications in the application domain to be synchronized, thereby improving the accuracy and efficiency of fault detection data and reducing bus load.

[0055] In step S205, fault detection data is sent to the target synchronization application so that the target synchronization application can perform association operations based on the fault detection data.

[0056] In one specific embodiment, the association operation can be an operation performed by the target synchronization application on fault detection data.

[0057] In an optional embodiment, applications in the target detection application domain have a first association relationship, and applications in the target application and the application domain to be synchronized have a second association relationship. Sending fault detection data to the target synchronization application so that the target synchronization application performs an association operation based on the fault detection data includes: When the target synchronization application is an application in the target detection application domain, fault detection data is sent to the application in the target detection application domain so that the application in the target detection application domain performs a first association operation based on the first association relationship and the fault detection data; When the target application to be synchronized is an application in the application domain to be synchronized, fault detection data is sent to the application in the application domain to be synchronized, so that the application in the application domain to be synchronized performs a second association operation based on the second association relationship and the fault detection data.

[0058] In a specific embodiment, the first association relationship can be the intra-domain relationship between applications in the target detection application domain. For example, the target detection application domain can be the power domain, and correspondingly, the target detection application domain can include power system units (internal combustion engine, electric motor, battery, transmission, etc.), and the association relationship between the power system units can be the first association relationship.

[0059] In a specific embodiment, the second association relationship can be the domain relationship between the target application and the application domain to be synchronized. For example, the target detection application domain can be the power domain, and the application domain to be synchronized can be the chassis domain, cockpit domain, body domain, etc. Correspondingly, the association relationship between the power domain and the chassis domain, cockpit domain, body domain, etc. can be the second association relationship.

[0060] In the above embodiments, by sending fault detection data to applications in the same domain or across domains associated with the target application, the applications in the same domain or across domains can perform corresponding operations based on their association with the target application, thereby improving the real-time performance and reliability of fault detection.

[0061] As can be seen from the technical solutions provided in the embodiments of this specification above, this specification receives a detection synchronization message for a target application in a multi-application collaborative system, sends a fault detection instruction to the target application to enable the target application to perform fault detection and obtain fault detection data; wherein, the target application is the application with the target address in the target detection application domain; the detection synchronization message includes a message propagation flag indicating whether to send the fault detection data to the application with the target address, a cross-domain flag indicating whether to send the fault detection data to the application domain to be synchronized, and an application domain identifier to be synchronized; based on the message propagation flag, the cross-domain flag, the target address, and / or the application domain identifier to be synchronized, the target synchronization application corresponding to the fault detection data is determined from the multi-application collaborative system including the target detection application domain and the application domain to be synchronized; the sending range of the fault detection data can be accurately determined based on the flags and the application domain identifier to be synchronized in the detection synchronization message, and the fault detection data is only sent to the collaborative application that needs to be synchronized, improving the granularity and flexibility of communication; sending the fault detection data to the target synchronization application enables the target synchronization application to perform association operations based on the fault detection data; and the efficiency of fault detection can be improved by sending the fault detection data to the collaborative application that needs to be synchronized to enable the collaborative application to perform association operations.
