[0002] LiDAR is a commonly used ranging sensor with the characteristics of long detection distance, high resolution, and low environmental interference. It is widely used in vehicles, ships, aircraft, robots and other fields. For example, in recent years, the rapid development of autonomous driving technology for automobiles, and LiDAR as a key distance sensing sensor, its normal operation is crucial.

[0003] When a laser radar fails, it is generally tested by on-site maintenance personnel, who then perform maintenance tests on the laser radar based on the fault diagnosis feedback.

[0004] Existing fault diagnosis methods for lidars have poor real-time performance, resulting in low fault diagnosis efficiency and requiring maintenance personnel to go to the site, resulting in a large amount of manpower costs. Summary of the Invention

The expert-side terminal then obtains the fault diagnosis result corresponding to the operating data, and receives a fault troubleshooting plan corresponding to the fault diagnosis result input by the expert. The fault diagnosis terminal then sends the fault troubleshooting plan corresponding to the fault diagnosis result received by the expert-side terminal to the user-side terminal, so that the user can use the fault troubleshooting plan to troubleshoot the faulty radar to be tested. That is, the user-side terminal and the expert-side terminal are remotely connected through the network, so that the expert can perform fault testing and diagnosis on the faulty radar to be tested in real time through the expert-side terminal, and use the fault diagnosis terminal to send the fault troubleshooting plan to the user-side terminal, thereby realizing remote diagnosis and troubleshooting of radar faults, with high real-time diagnosis, and improving the fault diagnosis efficiency of the radar. At the same time, there is no need for experts to go to the site of the faulty radar to be tested, which reduces labor costs.

[0010] In one embodiment, a fault diagnosis terminal includes: an expert-side diagnostic module and a user-side diagnostic module, both interconnected. The expert-side diagnostic module is deployed in the expert-side terminal, while the user-side diagnostic module is deployed in the user-side terminal.

This reduces the time it takes for the expert to enter troubleshooting solutions multiple times for the same fault, further improving radar troubleshooting efficiency.

It should be noted that the term "or" is generally employed in its sense including "or / and" unless the context clearly dictates otherwise.

[0034] In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used for description, but words such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and should not be understood as restrictive terms.

[0035] The first embodiment of the present invention relates to a radar remote fault diagnosis system, which is used to remotely test the radar used by the user, receive test data returned by the radar, and then obtain corresponding fault diagnosis results, and provide a fault troubleshooting solution corresponding to the fault diagnosis results in real time; the radar can be a commonly used laser radar.

[0036] Please refer to Figure 1The radar remote fault diagnosis system includes a user-side terminal 1, an expert-side terminal 2, and a fault diagnosis terminal 3 connected to the user-side terminal 1 and the expert-side terminal 2, respectively. The user-side terminal 1 is connected to the faulty radar 4 to be tested. The user-side terminal 1 and the expert-side terminal 2 can be electronic devices such as laptops and mobile phones.

[0037] The fault diagnosis terminal 3 is configured to send at least one test command to the faulty radar 4 under test via the user-side terminal 1. The fault diagnosis terminal 3 is also configured to receive, via the user-side terminal 1, operational data generated when the faulty radar 4 under test executes the at least one test command. The expert-side terminal 2 is configured to obtain a fault diagnosis result corresponding to the operational data and receive a troubleshooting solution corresponding to the fault diagnosis result input by the expert.

[0038] The fault diagnosis terminal 3 is further configured to send the fault elimination solution corresponding to the fault diagnosis result received by the expert side terminal 2 to the user side terminal 1 .

[0039] When a radar malfunctions, the radar user shuts down the radar's operating program and uses user-side terminal 1 to establish a communication connection with the faulty radar 4 under test. This connection can be via a CAN bus or the Internet. Data exchange between the user-side terminal 1 and the faulty radar 4 can be performed via PTC or a Common Gateway Interface (CGI). At this point, user-side terminal 1 also establishes a communication connection with expert-side terminal 2, which can be via the Internet or TCP. The connection between user-side terminal 1 and expert-side terminal 2 is established by: user-side terminal 1 sends a radar diagnosis request to expert-side terminal 2, which responds and sends a diagnosis instruction to user-side terminal 1, thereby establishing a remote connection between user-side terminal 1 and expert-side terminal 2. Expert-side terminal 2 is indirectly connected to the faulty radar 4 through user-side terminal 1. Alternatively, expert-side terminal 2 sends a radar diagnosis request to user-side terminal 1, which responds, and expert-side terminal 2 sends a diagnosis instruction to user-side terminal 1, thereby establishing a remote connection between user-side terminal 1 and expert-side terminal 2. Expert-side terminal 2 is indirectly connected to the faulty radar 4 through user-side terminal 1.

[0040] After the expert terminal 2 establishes a connection with the faulty radar under test via the user terminal 1, the fault diagnosis terminal 3 sends at least one test command to the faulty radar under test 4 via the user terminal 1. The faulty radar under test 4 receives and executes the received test command, then sends the operating data obtained from executing the test command to the user terminal 1. The user terminal 1 then sends the received operating data to the fault diagnosis terminal 3. The test command sent by the fault diagnosis terminal 3 may be a test command preset in the fault diagnosis terminal 3, but is not limited thereto. It may also be a test command input by an expert into the fault diagnosis terminal 3 via the expert terminal 2.

[0041] Subsequently, the expert side terminal 2 obtains the fault diagnosis result corresponding to the operating data, and receives the fault troubleshooting plan corresponding to the fault diagnosis result input into the expert side terminal 2 by the expert (who may be the radar R&D personnel or after-sales service personnel) after reviewing the fault diagnosis result. The fault diagnosis terminal 3 can then obtain the fault troubleshooting plan corresponding to the fault diagnosis result from the expert side terminal 2, and send the fault troubleshooting plan corresponding to the fault diagnosis result to the user side terminal 1, so that the user can read the fault troubleshooting plan from the user side terminal 1, and perform maintenance and other operations on the faulty radar 4 to be tested based on the fault troubleshooting plan, thereby realizing fault troubleshooting of the faulty radar 4 to be tested.

[0042] In this embodiment, the faulty radar 4 under test includes multiple functional components, such as a radar rotating component, a transmitting component, and a receiving component. Each test instruction is used to test one or more functional components of the faulty radar 4 under test. After receiving the test instruction, the faulty radar 4 under test executes the test instruction to control the corresponding functional component to operate and records the operating data of the functional component during operation. For example, the operating data of the radar rotating component includes rotation speed, operating voltage and current during rotation, radar temperature, operating time, etc.

[0043] The fault diagnosis terminal 3 then obtains the operating data of each functional component through the user-side terminal 1. The fault diagnosis result obtained by the expert-side terminal 2 includes information indicating the faulty functional component. The fault diagnosis terminal 3 can sequentially send multiple test instructions to the faulty radar 4 through the user-side terminal 1. If the fault diagnosis result of the faulty radar 4 cannot be determined based on the operating data of the functional component obtained by executing the current test instruction, the next test instruction will be sent to the faulty radar 4 until the fault diagnosis result of the faulty radar 4 can be determined.

[0044] In this embodiment, when a radar fails, the fault diagnosis terminal can send at least one test instruction to the faulty radar to be tested through the user side terminal, and receive the operating data obtained when the faulty radar to be tested executes at least one test instruction through the user side terminal. The expert side terminal then obtains the fault diagnosis result corresponding to the operating data, and receives the fault troubleshooting plan corresponding to the fault diagnosis result input by the expert. The fault diagnosis terminal then sends the fault troubleshooting plan corresponding to the fault diagnosis result received by the expert side terminal to the user side terminal, so that the user can use the fault troubleshooting plan to troubleshoot the faulty radar to be tested; that is, the user side terminal and the expert side terminal are remotely connected through the network, so that the expert can perform fault testing and diagnosis on the faulty radar to be tested in real time through the expert side terminal, and use the fault diagnosis terminal to send the troubleshooting plan to the user side terminal, thereby realizing remote diagnosis and troubleshooting of radar faults, with high real-time diagnosis, and improving the fault diagnosis efficiency of the radar; at the same time, there is no need for experts to go to the site of the faulty radar to be tested, reducing labor costs.

[0045] The second embodiment of the present invention relates to a radar remote fault diagnosis system. Compared with the first embodiment, the second embodiment provides a specific structure of the fault diagnosis terminal 3.

[0046] Please refer to Figure 2 The fault diagnosis terminal 3 includes a user-side diagnostic module 31 and an expert-side diagnostic module 32, which are interconnected. The user-side diagnostic module 31 is deployed in the user-side terminal 1 and may be a radar diagnostic application deployed in the user-side terminal 1. The expert-side diagnostic module 32 is deployed in the expert-side terminal 2 and may be a radar diagnostic application deployed in the expert-side terminal 2. The connection between the user-side diagnostic module 31 and the expert-side diagnostic module 32 is the connection between the user-side terminal 1 and the expert-side terminal 2. The connection can be an Internet connection or a TCP connection, preferably a TCP connection, which ensures better data confidentiality during data transmission.

[0047] In this embodiment, the user-side diagnostic module 31 and the expert-side diagnostic module 32 can be used to implement different functions, such as displaying different data contents. For example, if the radar motor is damaged, the expert-side diagnostic module 32 can send a test command to the radar, display information such as the motor's test voltage and temperature, and provide the corresponding fault code. The user-side diagnostic module 31 can simply display "motor operating fault" and provide the corresponding fault code. For another example, the expert can configure whether the test command and operating data are displayed in the user-side diagnostic module 31 in the expert-side diagnostic module 32. This allows users to further understand the radar's operating parameters while also ensuring the confidentiality of key radar parameters that require protection.

[0048] The expert-side diagnostic module 32 is configured to send at least one test instruction to the user-side diagnostic module 31 .

[0049] The user-side diagnosis module 31 is used to send at least one test instruction to the faulty radar 4 to be tested via the user-side terminal 1 , and receive operation data obtained when the faulty radar 4 to be tested executes the at least one test instruction.

[0050] The expert-side diagnosis module 32 is used to send a troubleshooting solution to the user-side terminal 1 through the user-side diagnosis module 31 .

[0051] Specifically, when the user-side terminal 1 establishes a communication connection with the expert-side terminal 2, the user-side terminal 1 starts the user-side diagnostic module 31, and the expert-side terminal 2 starts the expert-side diagnostic module 32. The expert-side terminal 2 is remotely connected to the faulty radar 4 to be tested indirectly through the user-side terminal 1. At this time, the expert can directly input the test instruction to the expert-side diagnostic module 32 through the expert-side terminal 2, or the expert-side diagnostic module 32 can use the test instruction preset in the expert-side terminal 2. Then the expert-side diagnostic module 32 sends the test instruction to the user-side diagnostic module 31. The user-side diagnostic module 31 then sends the test instruction to the faulty radar 4 to be tested through the user-side terminal 1. The faulty radar 4 to be tested receives and executes the received test instruction. The user-side diagnostic module 31 then receives the operating data obtained when executing the test instruction sent by the faulty radar 4 to be tested through the user-side terminal 1.

[0052] The expert terminal 2 obtains the fault diagnosis results corresponding to the operation data in the following two ways:

[0053] In the first approach, the user-side diagnostic module 31 is configured to transmit operating data to the expert-side terminal 2 via the expert-side diagnostic module 32; the expert-side terminal 2 is configured to receive the fault diagnosis result corresponding to the operating data input by the expert. Specifically, the user-side diagnostic module 31 transmits the operating data to the expert-side terminal 2 via the expert-side diagnostic module 32. The expert-side terminal 2 then displays the operating data of the faulty radar 4 under test for the expert to review. The expert then determines the fault diagnosis result corresponding to the operating data based on the operating data and enters the corresponding fault diagnosis result into the expert-side terminal 2. In other words, the expert-side terminal 2 can receive the fault diagnosis result corresponding to the operating data input by the expert.

[0054] In the second approach, the user-side diagnostic module 31 obtains a fault diagnosis result corresponding to the operating data based on the operating data, and transmits the fault diagnosis result to the expert-side terminal 2 via the expert-side diagnostic module 32. Specifically, after receiving the operating data of the faulty radar under test via the user-side terminal 1, the user-side diagnostic module 31 obtains the fault diagnosis result corresponding to the operating data based on the correspondence between the operating data and the fault diagnosis result preset in the user-side terminal 1, and then transmits the fault diagnosis result to the expert-side terminal 2 via the expert-side diagnostic module 32.

[0055] It should be noted that the processing after the expert-side terminal 2 obtains the fault diagnosis result corresponding to the operation data is similar to that of the first embodiment and will not be repeated here.

[0056] Compared with the first embodiment, this embodiment provides a specific structure of a fault diagnosis terminal.

[0057] The third embodiment of the present invention relates to a radar remote fault diagnosis system. The third embodiment has the following major improvements compared to the first embodiment: Figure 3 The radar remote fault diagnosis system further includes: a post-processing diagnosis terminal 5 connected to the fault diagnosis terminal 3.

[0058] In this embodiment, the post-processing diagnostic terminal 5 is used to obtain the troubleshooting solution corresponding to the fault diagnosis result input by the expert from the fault diagnosis terminal 3, and to generate and store fault diagnosis information including the troubleshooting solution corresponding to the fault diagnosis result. Specifically, the post-processing diagnostic terminal 5 can be connected to the fault diagnosis terminal 3 via the Internet, so that the post-processing diagnostic terminal 5 can obtain the troubleshooting solution corresponding to the fault diagnosis result input by the expert from the expert-side terminal 2 through the fault diagnosis terminal 3, and generate and store fault diagnosis information, which includes the fault diagnosis result and the troubleshooting solution corresponding to the fault diagnosis result. The fault diagnosis information can be stored in the form of text, and can be commanded based on the fault diagnosis result. For example, when generating the fault diagnosis information, a fault code corresponding to the fault diagnosis result contained in the fault diagnosis information is first generated, and then the fault code is used as the name of the fault diagnosis information. In one example, the fault diagnosis information also includes a test instruction and the operating data obtained by running the test instruction for the fault to be tested.

[0059] In this embodiment, the post-processing diagnostic terminal 5 can be a server connected to the expert side terminal 2, for example: the post-processing diagnostic terminal 5 is a local data storage server of the expert side terminal 2, or the post-processing diagnostic terminal 5 is a data storage server set up elsewhere, and the data storage server and the expert side terminal 2 are connected through the Internet network for data transmission.

[0060] The fault diagnosis terminal 3 is further configured to, after determining the target fault diagnosis result of the fault radar 4 to be tested, query the post-processing diagnosis terminal 5 whether there is a troubleshooting solution corresponding to the target fault diagnosis result. Specifically, each time the fault diagnosis terminal 3 is connected to the fault radar 4 to be tested, after determining the target fault diagnosis result of the fault radar 4 to be tested via the expert-side terminal 2, first query the post-processing diagnosis terminal 5 whether there is a troubleshooting solution corresponding to the target fault diagnosis result. The specific query method may be: first generate a target fault code corresponding to the target fault diagnosis result, and then query the post-processing diagnosis terminal 5 for a fault code matching the target fault code based on the target fault code, thereby obtaining the fault diagnosis information corresponding to the target fault code, and then obtaining the troubleshooting solution corresponding to the target fault diagnosis result from the fault diagnosis information.

[0061] The fault diagnosis terminal 3 is configured to, upon finding that a troubleshooting solution corresponding to the target fault diagnosis result exists in the post-processing diagnosis terminal 5, send the troubleshooting solution corresponding to the target fault diagnosis result in the post-processing diagnosis terminal 5 to the expert-side terminal 2 and / or the user-side terminal 1. The post-processing diagnosis terminal 5 and the user-side terminal 1 are connected via the Internet for data transmission.

[0062] In one example, the post-processing diagnostic terminal 5 is further configured to establish a correspondence between the faulty radar 4 to be tested and the fault diagnostic information. When the fault diagnostic terminal is connected to the faulty radar 4 to be tested, the post-processing diagnostic terminal 5 is configured to display at least one historical fault diagnostic information corresponding to the faulty radar 4 to be tested on the expert-side terminal 2 via the fault diagnostic terminal 3. Specifically, when generating fault diagnostic information, the post-processing diagnostic terminal 5 simultaneously establishes a correspondence between the faulty radar 4 to be tested and the fault diagnostic information. For example, the post-processing diagnostic terminal 5 obtains the device code of the faulty radar 4 to be tested, and then establishes a correspondence between the device code and the generated fault diagnostic information. Thus, after the fault diagnostic terminal 3 establishes a communication connection with the faulty radar 4 to be tested, based on the fault code of the faulty radar 4 to be tested, the post-processing diagnostic terminal 5 transmits the historical fault diagnostic information of the faulty radar 4 to the fault diagnostic terminal 3. The fault diagnostic terminal 3 can then display the historical fault diagnostic information of the currently faulty radar on the expert-side terminal 2 for the expert to view and reference, thereby further reducing fault diagnosis time.

[0063] Compared with the first embodiment, after determining the fault diagnosis result of the faulty radar to be tested, the fault diagnosis terminal in this embodiment can directly query the fault troubleshooting plan corresponding to the fault diagnosis result from the post-processing diagnosis module, and then send the fault troubleshooting plan to the user-side terminal for the user to execute the fault troubleshooting plan to solve the radar fault, thereby reducing the time for experts to enter the troubleshooting plan multiple times for the same fault, and further improving the efficiency of radar troubleshooting.

[0064] The fourth embodiment of the present invention relates to a radar remote fault diagnosis system. The fourth embodiment is relative to the third embodiment: please refer to Figure 4 The fault diagnosis terminal 3 includes a user-side diagnosis module 31 and an expert-side diagnosis module 32 connected to each other. The specific structure of the fault diagnosis terminal 3 is described in detail in the second embodiment and will not be described in detail here.

[0065] The post-processing diagnostic terminal 5 can be a server connected to the expert side diagnostic module 32. The post-processing diagnostic terminal 5 can obtain the fault troubleshooting solution corresponding to the fault diagnosis result input by the expert from the expert side terminal 2 through the expert side diagnostic module 32, and generate fault diagnosis information. The fault diagnosis information includes the fault diagnosis result and the fault troubleshooting solution corresponding to the fault diagnosis result.

[0066] After the expert side diagnostic module 32 determines the target fault diagnosis result of the fault radar 4 to be tested through the expert side terminal 2, it first queries the post-processing diagnostic terminal 5 whether there is a troubleshooting solution corresponding to the target fault diagnosis result. The specific query method can be: first generate a target fault code corresponding to the target fault diagnosis result, and then query the fault code matching the target fault code from the post-processing diagnostic terminal 5 based on the fault code, so as to obtain the fault diagnosis information corresponding to the target fault code, and then obtain the troubleshooting solution corresponding to the target fault diagnosis result from the fault diagnosis information.

[0067] When the expert side diagnostic module 32 finds that there is a troubleshooting solution corresponding to the target fault diagnosis result in the post-processing diagnostic terminal 5, the troubleshooting solution corresponding to the target fault diagnosis result in the post-processing diagnostic terminal 5 is sent to the expert side terminal 2 and / or the user side terminal 1 through the user side diagnostic module 31.

[0068] The fifth embodiment of the present invention relates to a radar remote fault diagnosis system. The fifth embodiment has the following major improvements compared to the third embodiment: Figure 5 The radar remote fault diagnosis system also includes: a cloud diagnosis terminal 6 connected to the user side terminal 1 and the fault diagnosis terminal 3 respectively.

[0069] The cloud-based diagnostic terminal 6 is used to store the troubleshooting solutions corresponding to the fault diagnosis results. Specifically, the cloud-based diagnostic terminal 6 can be a cloud server connected to both the user-side terminal 1 and the fault diagnosis terminal 3 via the Internet. Thus, when the expert-side terminal 2 receives the troubleshooting solution corresponding to the fault diagnosis result input by the expert, the cloud-based diagnostic terminal 6 can retrieve the troubleshooting solution corresponding to the expert-entered fault diagnosis result from the expert-entered fault diagnosis terminal 2 via the fault diagnosis terminal 3 and store it. The cloud-based diagnostic terminal 6 can also store the troubleshooting solution corresponding to the fault code of the fault diagnosis result. The cloud-based diagnostic terminal 6 is connected to the user-side terminals 1 of all radars, and the troubleshooting solutions corresponding to the fault diagnosis results stored in the cloud-based diagnostic terminal 6 are shared with radar users.

[0070] In this embodiment, the cloud diagnostic terminal 6 can also be connected to the post-processing diagnostic terminal 5 and / or the expert side terminal 2 through the Internet, so as to directly obtain the troubleshooting solutions corresponding to each fault diagnosis result from the post-processing diagnostic terminal 5 and / or the expert side terminal 2 for storage.

[0071] The user-side terminal 1 is also used to send user test instructions to the faulty radar 4 to be tested, and receive user test data obtained when the faulty radar 4 to be tested executes the user test instructions, and then obtain the user diagnosis result of the faulty radar 4 to be tested based on the user test data, and then obtain the troubleshooting solution corresponding to the user diagnosis result from the cloud diagnostic terminal 6.

[0072] Specifically, when the user-side terminal 1 establishes a connection with the faulty radar 4 to be tested, it can perform a fault test on the radar to be tested as needed, send a user test instruction to the faulty radar 4 to be tested, and control the faulty radar to be tested to perform a self-test. The user test instruction can be an instruction preset in the user-side terminal 1; after receiving the user test instruction, the faulty radar 4 to be tested executes the user test instruction to obtain user test data, and sends the user test data to the user-side terminal 1. The user-side terminal 1 obtains a user diagnosis result corresponding to the user test data based on the user test data and the preset correspondence between the user test data and the user diagnosis result. The user diagnosis result also indicates the fault of the faulty radar 4 to be tested. The user-side terminal 1 can then query from the cloud diagnosis terminal 6. The specific query method can be: first generate a fault code corresponding to the user diagnosis result, and then query the cloud diagnosis terminal 6 for the corresponding troubleshooting plan based on the fault code. The troubleshooting plan is the troubleshooting plan corresponding to the user diagnosis result, so that the user can perform maintenance and other operations on the faulty radar 4 to be tested based on the troubleshooting plan, thereby achieving troubleshooting of the faulty radar 4 to be tested.

[0073] In one example, the cloud diagnostic terminal 6 is also used to record operation information including user diagnostic results and troubleshooting solutions corresponding to the user diagnostic results, and send the operation information to the fault diagnosis terminal 5, so that experts can check the user's operation information in the user side terminal 1 from the fault diagnosis terminal 5 through the expert side terminal 2, which is convenient for experts to follow up on the radar fault condition.

[0074] Compared with the third embodiment, this embodiment uses the cloud-based diagnostic terminal to store the troubleshooting solution corresponding to the fault diagnosis result. The user-side terminal can send a user test instruction to the faulty radar to be tested, and receive user test data obtained when the faulty radar to be tested executes the user test instruction. Then, based on the user test data, the user diagnosis result of the faulty radar to be tested is obtained, and then the troubleshooting solution corresponding to the user diagnosis result is directly obtained from the cloud-based diagnostic terminal. That is, the user-side terminal can perform fault diagnosis on the faulty radar to be tested by itself, and access the cloud-based diagnostic terminal to obtain the troubleshooting solution, which further improves the efficiency of radar fault diagnosis and saves the cost and time of employing experts.

[0075] The sixth embodiment of the present invention relates to a radar remote fault diagnosis system. The sixth embodiment is different from the fifth embodiment. Figure 6 and Figure 7 The following description will be made by taking the fault diagnosis terminal 3 as an example, which includes: a user-side diagnosis module 31 and an expert-side diagnosis module 32 connected to each other. Please refer to the second embodiment for the specific structure of the fault diagnosis terminal 3, which will not be repeated here.

[0076] The cloud diagnostic terminal 6 is connected to the user-side diagnostic module 31. When the user-side terminal 1 establishes a connection with the fault radar 4 to be tested, the user-side diagnostic module 31 is started. The user-side diagnostic module 31 sends a user test instruction to the fault radar 4 to be tested through the user-side terminal 1, and controls the fault radar to be tested to perform a self-test. After receiving the user test instruction, the fault radar 4 to be tested executes the user test instruction to obtain user test data, and sends the user test data to the user-side terminal 1. The user-side diagnostic module 31 obtains the user test data according to the user test data and the preset correspondence between the user test data and the user diagnosis result. The user diagnosis result corresponding to the test data also indicates the fault of the faulty radar 4 to be tested. The user-side diagnosis module 31 then queries from the cloud-based diagnosis terminal 6. The specific query method can be: first generate a fault code corresponding to the user diagnosis result, and then query the corresponding troubleshooting solution from the cloud-based diagnosis terminal 6 based on the fault code and display it in the user-side terminal 1. The troubleshooting solution is the troubleshooting solution corresponding to the user diagnosis result, so that the user can perform maintenance and other operations on the faulty radar 4 to be tested based on the troubleshooting solution, thereby realizing the troubleshooting of the faulty radar 4 to be tested.

[0077] In this embodiment, the user-side diagnostic module 31 can realize similar functions as the expert-side diagnostic module 32, such as displaying the same data content; taking the radar motor as an example, if the motor fails, the user-side diagnostic module 31 can send a test instruction to the radar, display the motor's test voltage, temperature and other information, display "motor operation failure", and provide a corresponding fault code.
