All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] Example 1

[0054] Please refer to Figure 1 , which is a flow chart of a method for remotely repairing a terminal fault provided by one embodiment of the present invention, including:

[0055] S1. Obtain the test data, fault judgment rule set and repair solution library of the terminal to be tested; wherein the test data includes: terminal status data, terminal parameter setting data, terminal operation data, terminal log data and terminal task execution result data.

[0056] It should be noted that the terminal status data includes the terminal's online status, working mode and alarm status; the terminal parameter setting data includes clock settings, communication parameters and sampling rate; the terminal operation data includes: real-time collected electric energy data such as voltage, current and power; the terminal log data includes operation logs, exception logs and communication logs; the terminal task execution result data includes: the execution status and return value after the task template is issued.

[0057] S2. Determine whether the terminal to be tested is faulty based on the test data and the fault judgment rule set. If so, further determine the cause of the fault.

[0058] In step S2, when the judgment structure is that the device under test is faulty, it means that one or more fault judgment rules in the fault judgment rule set are triggered, and the corresponding fault information needs to be sent to the front end of the metering automation master station.

[0059] In a preferred embodiment, before judging whether the terminal to be tested is faulty based on the test data and the fault judgment rule set, the method further includes:

[0060] Collecting a number of historical fault data; wherein the historical fault data includes: historical fault phenomena and historical fault causes; the historical fault phenomena include fault terminal status data, fault terminal parameter setting data, fault terminal operation data, fault terminal log data and fault terminal task execution result data;

[0061] For each historical fault data, determine the corresponding fault rule expression according to the historical fault phenomenon and historical fault cause;

[0062] Collect statistics on the fault rule expressions corresponding to all historical fault causes and generate a fault judgment rule set.

[0063] S3. Selecting several corresponding repair solutions from the repair solution library according to the cause of the fault.

[0064] In a preferred embodiment, the historical fault data further includes: an effective repair solution;

[0065] Before selecting a plurality of repair solutions from a set of repair solutions based on the cause of the fault, the method further includes:

[0066] Determine the correlation between all historical fault data based on the historical fault causes;

[0067] According to the correlation, the historical fault data is grouped to obtain a number of related fault groups;

[0068] For each associated fault group, counting the effective repair solutions of all historical fault data in the associated fault group, and generating a repair solution set corresponding to the associated fault group;

[0069] According to the cause of the fault, a number of corresponding repair solutions are selected from the repair solution library, including:

[0070] According to the fault cause, determine the corresponding associated fault group and the corresponding repair solution set;

[0071] All valid repair solutions in the repair solution set are selected as candidate repair solutions.

[0072] In this embodiment, after the associated fault groups are obtained, the associated fault groups may be further classified into different levels according to the degree of impact of the historical fault conditions corresponding to the groups on the communication of the metering automation master station.

[0073] Set up related fault groups based on the correlation between historical fault data, including:

[0074] 1. Analyze fault correlation: Analyze the correlation between various faults. For example, some faults may be caused by the same reason, or the occurrence of one fault may lead to the occurrence of other faults.

[0075] 2. Set related fault groups: According to the fault correlation, multiple related historical battles are set as a related fault group;

[0076] 3. Classification of related fault groups: Classify related fault groups according to their impact on the communication of the metering automation master station, for example, into level one, level two, and level three. Level one means that all faults in the related fault group have no or slight impact on the communication of the metering automation master station; level two means that all faults in the related fault group have an impact on the communication of the metering automation master station; level three means that all faults in the related fault group have a serious impact on the communication of the metering automation master station.

[0077] 4. Management of associated fault groups: add, modify, delete, and other operations on associated fault groups, and maintain the association between associated fault groups and terminal types, power supply units, etc.

[0078] Since the faults included in each associated fault group are divided according to fault correlation, the specific faults included may vary depending on different terminal types and application scenarios. For example, an associated fault group may include faults such as "terminal clock asynchrony" and "data collection abnormality". These faults may be caused by the same fault cause, or there may be a certain causal relationship between their fault causes. For example, clock asynchrony may cause data collection abnormality.

[0079] It should be noted that an effective repair plan is a repair plan that can effectively solve terminal failures based on historical failure symptoms and historical failure causes. The process of specifying an effective repair plan is as follows:

[0080] 1. Fault scenario analysis: In-depth analysis of the actual scenarios of various terminal faults to understand the causes, manifestations, and possible impacts of the faults. Causes of faults include equipment design and manufacturing defects, improper material selection, improper use, improper maintenance and untimely repairs, environmental factors, etc.

[0081] 2. Logical combination design: Design appropriate logical combinations based on the fault scenario, including series, parallel, conditional, and loop logic structures;

[0082] 3. Repair operation selection: Based on the needs of the logical combination, select the corresponding repair operation, such as terminal time synchronization, parameter reset, task template issuance, restart, cache clearing, etc. Fault manifestations include abnormal performance, abnormal appearance, abnormal sound, abnormal temperature, abnormal odor, etc.; the possible impact of the fault includes power supply interruption, equipment damage, safety hazards, economic losses, social impact, etc.

[0083] 4. Solution testing and optimization: Test the effectiveness of the repair solution in the actual environment, and optimize and adjust it based on the test results;

[0084] 5. Solution documentation: Record the repair solution in documented form, including fault scenario description, logical combination design, repair operation selection, test results and other information.

[0085] In a preferred embodiment, after generating the fault judgment rule set, the method further includes:

[0086] Get the user-defined fault judgment rules;

[0087] Adding the user-defined fault judgment rule to the fault judgment rule set;

[0088] After generating the repair solution set corresponding to the associated fault group, the method further includes:

[0089] Obtaining a user-defined repair solution for the associated fault group;

[0090] The customized repair solution is included in the repair solution set corresponding to the associated fault group.

[0091] In this embodiment, when adding a user-defined fault judgment rule, it is also necessary to review the user-defined fault judgment rule. After passing the review, the user-defined fault judgment rule is added to the fault judgment rule set.

[0092] S4. Calculate the repair cost of each candidate repair solution, and sort all candidate repair solutions in descending order of repair cost as the execution order of the repair solutions.

[0093] In a preferred embodiment, the historical fault data further includes: repair time, repair complexity and repair abnormality risk value;

[0094] Calculate the repair cost for each candidate repair option, including:

[0095] Based on the repair time, repair complexity and repair abnormality risk value corresponding to each candidate repair solution, the repair cost of the candidate repair solution is comprehensively calculated. Specifically, the following steps can be used to comprehensively calculate the repair cost:

[0096] 1. Define weights: Define weights for repair time, repair complexity, and repair anomaly risk. These weights reflect the importance of each factor in the repair cost, with the sum of the weights being 1.

[0097] 2. Quantitative indicators: Quantify the repair time, repair complexity, and repair anomaly risk into numerical values. For example, repair time can be expressed in hours, repair complexity can be expressed on a scale of 1 to 10, and repair anomaly risk can be expressed as a probability value.

[0098] 3. Calculate the weighted value: Multiply the quantitative value of each factor by its corresponding weight to obtain the weighted value of each factor.

[0099] 4. Sum: Add the weighted values ​​of all factors to obtain the total repair cost of the repair plan.

[0100] 5. Comprehensive evaluation: If necessary, other factors such as labor cost, material cost, etc. can also be considered and included in the calculation.

[0101] The specific calculation formula can be expressed as:

[0102] Repair cost = w1×repair time + w2×repair complexity + w3×repair abnormality risk value,

[0103] Among them, w1, w2, and w3 are the weights of repair time, repair complexity, and repair abnormality risk value respectively.

[0104] It should be noted that the repair time, repair complexity and repair abnormality risk values ​​are preset quantities, based on historical or manual settings.

[0105] S5. Execute the selected repair solutions in sequence according to the repair solution execution order, and perform a terminal repair verification operation after each selected repair solution is executed.

[0106] The terminal repair verification operation includes:

[0107] Reacquiring the test data of the terminal to be tested as verification data;

[0108] According to the verification data and the fault judgment rule set, it is judged whether the terminal to be tested is faulty. If not, the terminal to be tested is repaired successfully and the execution of the remaining repair solutions is stopped.

[0109] In step S5, the selected repair plans are executed in sequence according to the execution order. After each selected repair plan is executed, the terminal repair verification operation is used to check whether the terminal is repaired successfully. If the repair is not successful, the next repair plan is executed; if the repair is successful, the task is terminated.

[0110] In a preferred embodiment, before executing the selected repair solutions in sequence according to the repair solution execution order, the method further includes:

[0111] Determine whether all the candidate repair plans include the preferred repair plan. If so, the preferred repair plan will be executed first; wherein, the preferred repair plan includes: terminal time synchronization, terminal parameter resetting, task template issuance, terminal restart, cache clearing and factory settings restoration.

[0112] In this embodiment, the preferred repair solution is executed first, and then the candidate repair solutions are executed in sequence according to the execution order.

[0113] In a preferred embodiment, when all the repair solutions to be selected have been executed and the terminal to be tested has not been repaired successfully, a repair abnormality alarm is issued.

[0114] In this embodiment, if the remote repair solution cannot solve the terminal fault anomaly, a repair anomaly alarm is issued, and an on-site modification solution is implemented, and personnel are sent to the metering automation terminal site to troubleshoot the communication fault and repair the fault anomaly.
