[0048] It should be noted that the parts not described in detail in the embodiment of the present application can be referred to the description of the foregoing embodiments.

[0049] Referring to Figure 2 The meter fault detection method shown in the figure comprises:

[0052] S202, detecting a voltage loss fault of the target electric meter according to the electric meter voltages corresponding to the sampling moments, to obtain a voltage loss fault detection result of the target electric meter.

[0053] In this embodiment, the voltage loss fault detection result can be used to represent whether the target electric meter has a voltage loss fault. Specifically, a certain algorithm is used to detect the voltage loss fault of the target electric meter according to the electric meter voltages corresponding to the sampling moments, to obtain the voltage loss fault detection result of the target electric meter.

[0054] Optionally, the voltage loss fault detection result of the target electric meter is obtained by detecting the voltage loss fault of the target electric meter according to the electric meter voltages corresponding to the sampling moments, including: determining a first duration in which the electric meter voltage is less than or equal to a preset voltage threshold according to the electric meter voltages corresponding to the sampling moments; comparing the first duration with a first duration threshold to obtain a first comparison result; and determining the voltage loss fault detection result of the target electric meter according to the first comparison result.

[0055] The first duration is the duration in which the electric meter voltage is less than or equal to the preset voltage threshold in the period. It should be noted that the preset voltage threshold and the first duration threshold can be set by the technician according to the actual demand or practical experience, and the present application does not limit this.

[0056] Specifically, if the first comparison result is that the first duration is greater than or equal to the first duration threshold, it is determined that the voltage loss fault detection result of the target electric meter is that there is a voltage loss fault; if the first comparison result is that the first duration is less than the first duration threshold, it is determined that the voltage loss fault detection result of the target electric meter is that there is no voltage loss fault.

[0057] It can be understood that by using the above technical solution, the first duration in which the electric meter voltage is less than or equal to the preset voltage threshold is determined according to the electric meter voltages corresponding to the sampling moments; the first comparison result is obtained by comparing the first duration with the first duration threshold; and the voltage loss fault detection result of the target electric meter is determined according to the first comparison result, which improves the accuracy of the voltage loss fault detection result.

[0059] In this embodiment, the voltage loss fault detection result can be used to represent whether the target electric meter has a voltage loss fault. Specifically, a certain algorithm is used to detect the voltage loss fault of the target electric meter according to the electric meter voltages corresponding to the sampling moments, to obtain the voltage loss fault detection result of the target electric meter.

[0060] Optionally, the no-flow fault detection result of the target electric meter is obtained according to the electric meter current corresponding to each sampling time, and the no-flow fault detection result of the target electric meter is obtained by: determining a second duration in which the electric meter current is less than or equal to a preset current threshold according to the electric meter current corresponding to each sampling time; obtaining a second comparison result by comparing the second duration with a second duration threshold; and determining the no-flow fault detection result of the target electric meter according to the second comparison result.

[0061] The second duration is the duration in which the electric meter current is less than or equal to the preset current threshold in the period. It should be noted that the preset current threshold and the second duration threshold can be determined by the technical personnel according to actual needs or practical experience.

[0062] Specifically, if the second comparison result is that the second duration is greater than or equal to the second duration threshold, it is determined that the no-flow fault detection result exists; if the second comparison result is that the second duration is less than the second duration threshold, it is determined that the no-flow fault detection result does not exist.

[0063] It can be understood that, by using the above technical solution, the second duration in which the electric meter current is less than or equal to the preset current threshold can be determined according to the electric meter current corresponding to each sampling time; the second comparison result can be obtained by comparing the second duration with the second duration threshold; and the no-flow fault detection result of the target electric meter can be determined according to the second comparison result, thereby improving the accuracy of the no-flow fault detection result.

[0064] S204, the meter code fault detection result of the target electric meter is obtained by performing meter code fault detection on the target electric meter according to the electric meter code corresponding to each sampling time and the historical meter code.

[0065] In this embodiment, the meter code fault detection result can be used to represent whether the target electric meter has a meter code fault. Specifically, a certain algorithm is used to perform meter code fault detection on the target electric meter according to the electric meter code corresponding to each sampling time and the historical meter code, and the meter code fault detection result of the target electric meter is obtained.

[0067] Specifically, a matching historical period matching the period is queried; for example, the current period is from 7:00 to 8:00 on January 7, and the matching historical period of the period is from 7:00 to 8:00 on January 6. For each sampling time, the meter code difference between the meter code corresponding to the sampling time in the matching historical period and the meter code corresponding to the sampling time in the period is determined; it is detected whether there is a meter code difference greater than or equal to a preset difference threshold; if there is a meter code difference greater than or equal to the preset difference threshold, it is determined that the meter code fault detection result is that there is a meter code fault; if there is no meter code difference greater than or equal to the preset difference threshold, it is determined that the meter code fault detection result is that there is no meter code fault. It should be noted that the preset difference threshold can be set by the technician according to the actual demand or practical experience.

[0071] S206, determining the target detection result of the target meter according to the first detection result, the reverse power supply state and the meter current.

[0072] In an optional embodiment, after it is determined that the target detection result is abnormal, a warning information can also be sent to the technician, and the meter voltage, the meter current, the meter code and the reverse power supply state of the target meter in the period, and the historical meter code of the target meter can also be analyzed, thereby providing clear fault information and processing suggestions for the on-site maintenance personnel.

[0073] In still another optional embodiment, in order to realize long-term preservation and traceability of data, distributed storage technology can also be used to store the meter voltage, the meter current, the meter code and the reverse power supply state, and the historical meter code of the target meter, thereby ensuring the security and scalability of the data. At the same time, a convenient query interface is provided, which supports data retrieval according to time, meter number, fault type and other conditions, thereby providing strong support for fault analysis and system optimization.
