[0055] The first duration is the duration during which the meter voltage is less than or equal to the preset voltage threshold in the cycle. It should be noted that the preset voltage threshold and the first duration threshold can be independently set by technicians according to actual needs or practical experience, and the present invention does not limit this.

[0056] Specifically, if the first comparison result is that the first time length is greater than or equal to the first time length threshold, the pressure loss fault detection result of the target meter is determined to be that there is a pressure loss fault; if the first comparison result is that the first time length is less than the first time length threshold, then the pressure loss fault detection result of the target meter is determined to be that there is no pressure loss fault.

Specifically, a certain algorithm is used to perform a loss-of-current fault detection result on the target meter according to the meter current corresponding to each sampling moment to obtain the loss-of-current fault detection result of the target meter.

[0060] Optionally, a loss of current fault detection result is performed on the target meter based on the meter current corresponding to each sampling moment to obtain the loss of current fault detection result of the target meter, including: determining, based on the meter current corresponding to each sampling moment, a second time duration during which the meter current is continuously less than or equal to a preset current threshold; comparing the second time duration and the second time duration threshold to obtain a second comparison result; and determining the loss of current fault detection result of the target meter based on the second comparison result.

[0061] The second duration is the duration during which the current of the electric meter is continuously less than or equal to the preset current threshold value in the cycle. It should be noted that the preset current threshold value and the second duration threshold value can be determined by technicians according to actual needs or practical experience.

[0067] Specifically, query the matching historical cycle that matches the cycle; illustratively, the current cycle is the cycle from 7 to 8 o'clock on January 7, and the matching historical cycle of the cycle is the cycle from 7 to 8 o'clock on January 6. For each sampling moment, determine the meter code difference between the meter code corresponding to the sampling moment in the matching historical cycle and the meter code corresponding to the sampling moment in the cycle; detect whether there is a meter code difference greater than or equal to the preset difference threshold; if there is a meter code difference greater than or equal to the preset difference threshold, determine 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, determine 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 independently by technical personnel based on actual needs or practical experience.

[0070] Specifically, if the pressure loss fault detection result is that there is no pressure loss fault, the current loss fault detection result is that there is no current loss fault, and the table code fault detection result is that there is no table code fault, then the first detection result of the target meter is determined to be normal; otherwise, the first detection result of the target meter is determined to be abnormal.

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

[0072] In an optional embodiment, after determining that the target detection result is abnormal, a warning message can be sent to the technician, and the meter voltage, meter current, meter code and reverse power supply status of the target meter during the cycle, as well as the historical meter code of the target meter can be analyzed, thereby providing on-site maintenance personnel with clear fault information and handling suggestions.

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