[0076] This application provides a fault detection method, which is applied to a fault detection device. Figure 1 A flowchart of a fault detection method provided in an embodiment of this application is shown below. Figure 1 As shown, fault detection methods may include:
[0077] S101. Receive the target fault tree of the device under test; the target fault tree is a fault tree used to perform fault detection on the device under test.
[0078] The fault detection method provided in this application embodiment is applicable to scenarios where fault detection is performed on the equipment to be tested.
[0079] In the embodiments of this application, the fault detection device can be implemented in various forms. For example, the fault detection device described in this application may include servers, clouds, core networks, etc. The specific fault detection device can be determined according to the actual situation, and the embodiments of this application do not limit it in this regard.
[0080] In this embodiment of the application, the fault detection device can be a fault tree entry and analysis system set up in the cloud.
[0081] In this embodiment of the application, the device to be tested can be a vehicle, a computer, or other devices. The specific device to be tested can be determined according to the actual situation, and this embodiment of the application does not limit it.
[0082] For example, the device to be tested is specifically the vehicle-side controller (Electronic Control Unit, ECU) in a vehicle.
[0083] In this embodiment, the target fault tree can be information transmitted from other devices to the fault detection device, information manually entered into the fault detection device, or information obtained by the fault detection device through other means. The specific way in which the fault detection device receives the target fault tree of the device under test can be determined according to the actual situation, and this embodiment does not limit it.
[0084] In this embodiment, the target fault tree can be a manually set fault tree for fault detection of the device under test, or a fault tree generated by a fault tree generation device for fault detection of the device under test. The specific method of generating the target fault tree can be determined according to the actual situation, and this embodiment does not limit it.
[0085] In this application embodiment, an exemplary target fault tree is as follows: Figure 2As shown: The occurrence of any one of the basic events A or B will cause the intermediate event Node111 to occur, and the occurrence of Node111 will cause the intermediate event Node11 to occur; the occurrence of any one of the intermediate events Node11, Node12, and Node13 will cause the Node1 event to occur.

The occurrence of any one of the basic events G or H will cause the intermediate event Node131 to occur, and the occurrence of Node131 will cause the intermediate event Node13 to occur.
[0086] Specifically, such as Figure 3 As shown, Figure 2 The circles in the diagram represent basic events, which are events that do not require further development and are called bottom events. Figure 2 The rectangle in the diagram represents an intermediate event, which occurs due to one or more input events of a logic gate. Figure 2 In the diagram, the crescent-shaped symbol represents an OR gate, which means that an output event occurs when at least one of the input events occurs. The semi-circular symbol represents an AND gate, which means that an output event occurs only when all input events occur.
[0087] In this application embodiment, an exemplary target fault tree is as follows: Figure 4 As shown: If the device under test is a vehicle, and it cannot be charged, it may be due to operational or communication abnormalities. Operational abnormalities may be caused by the charging gun not being properly inserted. Communication abnormalities may be caused by the Controller Area Network (CAN) bus being in a bus-off state.
[0088] S102. Generate the fault detection code corresponding to the target fault tree.
[0089] In this embodiment of the application, after receiving the target fault tree of the device to be tested, the fault detection device generates the fault detection code corresponding to the target fault tree.
[0090] In this embodiment of the application, the process of the fault detection device generating the fault tree running code corresponding to the target fault tree includes: converting the target fault tree into code to obtain fault detection code.
[0091] It should be noted that the target fault tree includes the abnormal state of the device under test and the corresponding fault results.
[0092] In this embodiment, the fault detection device can write corresponding code according to the logical relationship between events in the target fault tree to obtain fault detection code. The fault detection device can also convert the target fault tree into code in other ways to obtain fault detection code; the specific method by which the fault detection device converts the target fault tree into code to obtain fault detection code can be determined according to the actual situation, and this embodiment does not limit this.
[0093] It should be noted that the fault detection code can be C language code, Java language code, or other encoding formats. The specific format can be determined based on the executable code format of the device under test. This application embodiment does not limit this.
[0094] S103. Send a fault detection code to the device under test.
[0095] In this embodiment of the application, after the fault detection device generates the fault detection code corresponding to the target fault tree, it sends the fault detection code to the device to be tested.
[0096] In this embodiment, a communication link is established between the fault detection device and the device under test, allowing the fault detection device to transmit information to the device under test via this link. Specifically, the fault detection device sends a fault detection code to the device under test through this communication link.
[0097] In the embodiments of this application, the specific method by which the fault detection device sends the fault detection code to the device under test can be determined according to the actual situation, and the embodiments of this application do not limit this.
[0098] In this embodiment of the application, if the fault detection device is a fault tree entry and analysis system set in the cloud and the device to be detected is a vehicle-side controller, then the fault tree entry and analysis system in the cloud sends a fault detection code to the vehicle-side controller.
[0099] S104. Receive the running results generated after receiving the fault detection code of the device under test.
[0100] In this embodiment of the application, after the fault detection device sends the fault detection code to the device under test, it receives the running result generated by the device under test after running the fault detection code.
[0101] In this embodiment of the application, after the fault detection device sends a fault detection code to the device under test through a communication link, it can continue to receive the operating results transmitted by the device under test through the same communication link.
[0102] In this embodiment, the specific method by which the fault detection device generates the running result after receiving the fault detection code from the device under test can be determined according to the actual situation, and this embodiment does not limit this.
[0103] In this embodiment of the application, if the fault detection device is a fault tree entry and analysis system set in the cloud and the device to be detected is a vehicle-side controller, then the fault tree entry and analysis system in the cloud receives the running results sent by the vehicle-side controller.
[0104] It should be noted that the results include the device number under test and the time information when the device under test ran the fault detection code.
[0105] S105. Based on the operation results, determine the fault detection results of the equipment to be tested.
[0106] In this embodiment of the application, after receiving the running result generated by the device under test after running the fault detection code, the fault detection device determines the fault detection result of the device under test based on the running result.
[0107] It should be noted that the running result is the matching result obtained after matching the device status information of the device under test with the information in the target fault tree.
[0108] In this embodiment of the application, the process of determining the fault detection result of the device under test based on the operation result includes: determining the operation result as the fault detection result.
[0109] It should be noted that the results are partial information from the target fault tree.
[0110] In this embodiment, the target fault tree is the logical causal relationship information of the fault of the device under test caused by any abnormality of any component in the device under test. During the execution of the fault detection code, the device status information of the device under test is matched with the target fault tree information, and the matching result is the information that identifies the fault detection result.
[0111] In this embodiment of the application, after the fault detection device determines the fault detection result of the equipment to be tested based on the operation results, it will also display the fault detection result so that the fault repair personnel can carry out fault repair processing on the equipment to be tested according to the fault detection result.
[0112] In this embodiment, the fault detection result can be displayed using a fault detection device, or the fault detection result can be sent to a display device for display. The specific method of displaying the fault detection result can be determined according to the actual situation, and this embodiment does not limit it.
[0113] It should be noted that the display device can be the equipment of the fault repair personnel, such as their mobile phone; the display device can also be a server, from which the fault repair personnel can obtain the fault detection result and display it on the server's screen; the display device can also be a device dedicated to displaying faults, whereby the fault detection result is displayed on the display device after the fault detection device obtains the fault detection result, so that the fault repair personnel can view the fault display result and perform fault repair on the equipment under test according to the fault detection result; the specific display device can be determined according to the actual situation, and this application embodiment does not limit it in this way.
[0114] For example, when the fault detection device determines the fault detection result of the device under test, it stores the fault detection result. When the person in charge of problem analysis and handling (i.e., the fault repair personnel) receives feedback from the vehicle user about the problem, the person in charge of problem analysis and handling can input the vehicle (device under test) number (VIN) and the time information of the time information of the vehicle (device under test) running the fault detection code into the fault detection device, and view the fault detection result corresponding to the time information and the vehicle number (i.e., display the fault detection result corresponding to the time information and the vehicle number). The person in charge of problem analysis and handling can then know the root cause of the vehicle's functional failure, quickly provide a solution, improve problem handling efficiency, and save problem analysis time.
[0115] Understandably, this application enables self-diagnosis of vehicle (device under test) malfunctions, directly pinpointing the root cause of the problem.
[0116] In this embodiment, after determining the fault detection result of the device under test based on the operation results, the fault detection device will also determine the fault solution corresponding to the fault detection result; and display the fault solution so that the fault repair personnel can handle the fault problem of the device under test according to the fault solution.
[0117] In this embodiment, the fault detection device is provided with a preset correspondence between fault detection results and preset fault solutions. The fault solution corresponding to the fault detection result can be found in the preset correspondence between the fault detection results and preset fault solutions.
[0118] It should be noted that the correspondence between the preset fault detection result and the preset fault solution can be information transmitted to the fault detection device from other devices, information configured in the fault detection device, or information obtained by the fault detection device through other means. The specific way in which the fault detection device obtains the correspondence between the preset fault detection result and the preset fault solution can be determined according to the actual situation, and this application embodiment does not limit it.
[0119] In this embodiment of the application, the fault solution is a solution to the problem of fault detection results in the device under test.
[0120] In this embodiment, the fault detection device can be used to display the fault solution, or the fault solution can be sent to a display device for display. The specific way of displaying the fault solution can be determined according to the actual situation, and this embodiment does not limit it.
[0121] Understandably, when the fault detection device receives the target fault tree of the device under test, it generates the corresponding fault detection code and sends the fault detection code to the device under test so that the device under test can run the fault detection code to obtain the running result. Based on the running result, the fault detection result of the device under test can be determined. There is no need for manual fault location, which improves the efficiency of fault detection of the device under test.
[0122] This application embodiment also provides a fault detection method, which is applied to the device under test. Figure 5 A flowchart of a fault detection method provided in an embodiment of this application is shown below. Figure 5 As shown, fault detection methods may include:
[0123] S201. Receive the fault detection code sent by the fault detection device.
[0124] The fault detection method provided in this application embodiment is applicable to scenarios where fault detection is performed on the equipment to be tested.
[0125] In the embodiments of this application, the device to be tested can be implemented in various forms. For example, the device to be tested described in this application may include vehicles, computers, mobile phones, controllers, etc. The specific device to be tested can be determined according to the actual situation, and the embodiments of this application do not limit it in this way.
[0126] In this embodiment of the application, the device to be tested can be the vehicle-side controller in the vehicle.
[0127] In this application embodiment, the fault detection device may include servers, cloud, core network, etc. The specific fault detection device can be determined according to the actual situation, and this application embodiment does not limit it.
[0128] For example, the fault detection device can be a fault tree entry and analysis system set up in the cloud.
[0129] In this embodiment, the fault detection code can be C language code, Java language code, or other encoding formats. The specific format can be determined based on the executable code format of the device under test, and this embodiment does not limit it.
[0130] In this embodiment, a communication link is established between the fault detection device and the device under test, allowing the fault detection device to transmit information with the device under test via the communication link. That is, the device under test can receive fault detection codes sent by the fault detection device through this communication link.
[0131] In this application embodiment, the specific way in which the device under test receives the fault detection code sent by the fault detection device can be determined according to the actual situation, and this application embodiment does not limit it.
[0132] In this embodiment of the application, if the fault detection device is a fault tree entry and analysis system set in the cloud, and the device to be detected is a vehicle-side controller, then the vehicle-side controller receives the fault detection code sent by the fault tree entry and analysis system in the cloud.
[0133] S202. Run the fault detection code and obtain the running results.
[0134] In this embodiment of the application, after the device under test receives the fault detection code sent by the fault detection device, it runs the fault detection code and obtains the running result.
[0135] In this embodiment of the application, the process of running fault detection code on the device under test and obtaining the running result includes: obtaining device status information of the device under test; running fault detection code based on the device status information and obtaining the running result.
[0136] It should be noted that the results are partial information from the target fault tree.
[0137] In this embodiment, the device status information refers to the status of different components in the device under test, including the rotational speed of the motor of the device under test. The specific device status information can be determined according to the actual situation, and this embodiment does not limit it.
[0138] In this embodiment of the application, the device under test can detect the status of its various components to obtain device status information. Alternatively, the device status information of the device under test can be obtained through other means. The specific method of obtaining the device status information of the device under test can be determined according to the actual situation, and this embodiment of the application does not limit it.
[0139] In this embodiment of the application, the process of the device under test running fault detection code based on device status information to obtain the running result includes: during the running of the fault detection code, matching the device status information with the information in the target fault tree to obtain the matched abnormal state and the fault result corresponding to the abnormal state.
[0140] Abnormal states and fault results are identified as operational outcomes.
[0141] In this embodiment of the application, the target fault tree is the logical causal relationship information of the fault of the device under test caused by any abnormality of any component in the device under test. During the execution of the fault detection code, the device status information of the device under test is matched with the target fault tree information to obtain the matching result, which is the running result.
[0142] It should be noted that the results include the device number under test and the time information when the device under test ran the fault detection code.
[0143] S203. Send the operation results to the fault detection device so that the fault detection device can determine the fault detection result based on the operation results.
[0144] In this embodiment of the application, after the device under test runs the fault detection code and obtains the running result, it sends the running result to the fault detection device so that the fault detection device can determine the fault detection result based on the running result.
[0145] In this embodiment, the device under test can send the operation results to the fault detection device through the communication link between the device under test and the fault detection device. The specific method by which the device under test sends the fault detection results to the fault detection device can be determined according to the actual situation, and this embodiment does not limit it.
[0146] It should be noted that if the fault detection device is a fault tree entry and analysis system set up in the cloud, and the device to be tested is a vehicle-side controller, then the vehicle-side controller sends the operation results to the fault tree entry and analysis system in the cloud, so that the fault tree entry and analysis system in the cloud can determine the fault detection result based on the operation results.
[0147] For example, such as Figure 6The system block diagram of the fault detection method shown includes a fault detection device (a cloud-based fault tree input and analysis system) and the device under test (a fault tree running system (i.e., the vehicle-side ECU)). Upon receiving the target fault tree from the device under test, the fault detection device generates a fault detection code corresponding to the target fault tree and then sends the fault detection code to the device under test (the fault tree is sent to the vehicle-side ECU). Upon receiving the fault detection code from the fault detection device, the device under test runs the fault detection code, obtains the running result, and then sends the running result back to the fault detection device (the fault tree running result is output and reported), so that the fault detection device can determine the fault detection result based on the running result.
[0148] Understandably, when the device under test receives a fault detection code, it can obtain the running result by running the fault detection code, and then send the running result to the fault detection device so that the fault detection device can determine the fault detection result of the device under test based on the running result. This eliminates the need for manual fault location and improves the efficiency of fault detection of the device under test.
[0149] Based on the same inventive concept as the above-mentioned fault detection method, this application provides a fault detection device 1, corresponding to a fault detection method; Figure 7 This is a schematic diagram of the composition of a fault detection device provided in an embodiment of this application.

[0150] The first receiving unit 11 is configured to receive the target fault tree of the device under test; the target fault tree is a fault tree used for fault detection of the device under test; and to receive the running results generated after the device under test runs the fault detection code.
[0151] Generation unit 12 is used to generate fault detection codes corresponding to the target fault tree;
[0152] The first sending unit 13 is used to send the fault detection code to the device under test;
[0153] The determining unit 14 is used to determine the fault detection result of the device under test based on the running results.
[0154] In some embodiments of this application, the apparatus further includes a conversion unit;
[0155] The conversion unit is used to convert the target fault tree into code to obtain the fault detection code; the target fault tree includes the abnormal state of the device under test and the fault result corresponding to the abnormal state.
[0156] In some embodiments of this application, the determining unit 14 is used to determine the running result as the fault detection result, wherein the running result is part of the information in the target fault tree.
[0157] In some embodiments of this application, the device further includes a display unit;

When the program is executed, the fault detection method described above is executed by the first processor 15.
[0163] In practical applications, the first memory 16 can be volatile memory, such as random-access memory (RAM); or non-volatile memory, such as read-only memory (ROM), flash memory, hard disk drive (HDD), or solid-state drive (SSD); or a combination of the above types of memory, and provide instructions and data to the first processor 15.
