[0021] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0022] Refer to Figure 1 , an embodiment of the present application provides a diagnostic system applied to an automotive fault diagnosis system, which includes a microprocessor 1 and a micro - control unit 2 communicatively connected to the microprocessor 1.

[0023] The diagnostic device 10 based on service - oriented architecture, which is applied to the microprocessor 1, includes:

[0024] A communication middleware 101, which is used to monitor the service communication between multiple service - based applications in real - time and obtain service faults generated by the service communication.

[0025] A service management module 102, which is used to receive the service faults fed back by the communication middleware and set the actual service status according to the service faults.

[0026] A diagnostic service module 103, which is used to obtain service faults through the communication service of the service - oriented architecture and send the service faults to the micro - control unit through the communication service of the service - oriented architecture, so that the micro - control unit stores the service faults and snapshot information of the service faults.

[0027] Refer to Figure 1 , the diagnostic device 20 based on service - oriented architecture, which is applied to the micro - control unit 2, includes:

[0028] A fault real - time recording module 201, which is used to receive the service faults sent by the microprocessor through the communication service of the service - oriented architecture and store the service faults and snapshot information of the service faults. The service faults are the service faults generated by the service communication obtained by the microprocessor monitoring the service communication between multiple communication applications of the service - oriented architecture in real - time.

[0029] In the embodiment of the present application, the communication middleware 101 monitors the service communication between multiple service - oriented architecture - based applications in real time. Based on the communication middleware 101, the service lists between multiple service - oriented architecture - based applications can be managed, so as to effectively monitor the service communication between multiple service - oriented architecture - based applications.

[0030] In the embodiment of the present application, the service management module 102 can centrally manage the failure states of all services. Through the storage method of multi - core heterogeneous communication in the embodiment of the present application, the storage of service failure information for the service - oriented architecture is realized, meeting the requirement of real - time diagnostic requests.

[0031] In the embodiment of the present application, through the snapshot information of service failures stored by the fault real - time recording module 201, the information recording at the time of service failures of all service - oriented architectures is realized, so as to facilitate the diagnostic engineer to understand the actual state of the vehicle at the time of the failure, improving the efficiency and accuracy of fault diagnosis.

[0032] Specifically, the service failures include at least one of service discovery failure, service response timeout, and periodic service timeout.

[0033] The communication for the service - oriented architecture is SOME / IP communication or DDS communication.

[0034] The diagnostic device of the embodiment of the present application will be further described in detail below for the types of service failures.

[0035] The communication middleware 101 monitors the service communication between multiple service - oriented architecture - based applications. Specifically, when it monitors that a client issues a Find Service instruction and fails to find the service required by the client, the communication middleware 101 sets a service discovery exception to the service management module 102. The service management module 102 sends the fault information of service discovery failure to the diagnostic service module 103 through the SOME / IP service or DDS service. The diagnostic service module 103 sends the service discovery failure to the fault real - time recording module 201, and the fault real - time recording module 201 stores the fault and the fault snapshot information.

[0036] When the communication middleware 101 monitors a request sent by the Client and the Server does not reply within the agreed time t, the communication middleware 101 sets a response timeout and sends it to the service management module 102. The service management module 102 sends the fault information of the response timeout to the diagnostic service module 103 through the SOME / IP service or the DDS service. The diagnostic service module 103 sends the fault of the response timeout to the fault real-time recording module 201, and the fault real-time recording module 201 stores the fault and the fault snapshot information. Those skilled in the art set the agreed time t as needed.

[0037] After the Client subscribes to the server periodic service successfully, when the communication middleware 101 monitors that the Client does not receive the periodic notification from the Server within N cycles, the communication middleware 101 sets a periodic service timeout and sends it to the service management module 102. The service management module 102 sends the fault information of the periodic service timeout to the diagnostic service module 103 through the SOME / IP service or the DDS service. The diagnostic service module 103 sends the fault of the periodic service timeout to the fault real-time recording module 201, and the fault real-time recording module 201 stores the fault and the fault snapshot information. Those skilled in the art set N cycles as needed, and N is a positive integer.

[0038] In some specific implementations of the embodiments of the present application, the service management module 102 is further configured to:

[0039] Receive a service configuration file and set an initial service state according to the service configuration file. The initial service state includes at least one of: service ID, service instance ID, service initial state default, service ID and service instance ID undefined, service available, and service unavailable.

[0040] In the embodiments of the present application, the service management module 102 realizes the configuration of the initial service state by parsing the configuration file, so as to effectively manage the initial service state through a simple method.

[0041] In some specific implementations of the embodiments of the present application, the service management module 102 is further configured to:

[0042] According to the actual diagnostic requirements of the diagnostic service module, provide service faults generated by service communication between applications based on the service architecture to the diagnostic service module.

[0043] In the embodiments of the present application, the service management module 102 can provide service fault information between SOME / IP or DDS applications to the diagnostic service module 103 according to the actual diagnostic requirements of the diagnostic service module 103.

[0044] In some specific implementations of the embodiments of the present application, refer to Figure 2, the diagnostic service module 103 is further configured to:

[0045] Receive the actual diagnostic requirements generated by the microcontroller unit 2 based on the requests of the diagnostic instrument 3, provide the service faults sent by the service management module 102 to the microcontroller unit 2, and cause the microcontroller unit 2 to feedback to the diagnostic instrument 3.

[0046] The diagnostic instrument 3 can send a request instruction to the fault real-time recording module 201 through the UDS diagnostic 31 service (Routine Control) to obtain the status of all services.

[0047] When the fault real-time recording module 201 receives a request based on the diagnostic instrument 3, the fault real-time recording module 201 actively queries the service faults of all services from the service management module 102 through the diagnostic service module 103, and feeds back the service faults to the fault real-time recording module 201, and finally feeds back to the diagnostic instrument 3.

[0048] In the embodiment of the present application, through the diagnostic instrument 3, diagnostic engineers can quickly obtain the service faults of all services, effectively improving the efficiency of diagnostic troubleshooting.
