Power supply line monitoring device and method

The invention discloses a power supply line monitoring device and method, and belongs to the technical field of line monitoring, the power supply line monitoring device comprises a fault indicator for circuit fault detection and a line clamping mechanism arranged at the top end of the fault indicator, and the top of the fault indicator is provided with a protection mechanism for performing safety protection on the fault indicator. The protection mechanism comprises a protection top seat, the protection top seat is arranged at the top of the fault indicator, and the inner side face of the protection top seat is slidably connected with a shielding plate. The shielding plate is sent out through the driving assembly, so that the shielding plate can be matched with shielding cloth, connecting strips, clamping strips and clamping grooves to form a stable and large-range protective screen, and objects falling off from the air can be effectively shielded; the condition that the fault indicator ...

Ammeter anomaly detection method and system

The invention provides an ammeter anomaly detection method and system, and the method comprises the steps: 1, a home gateway subsystem receives an electric appliance control command of a resident, generates an electric appliance collection power utilization event, and reports the electric appliance collection power utilization event to a cloud platform subsystem; step 2, the cloud platform subsystem inquires the electricity meter reading value of the resident electricity meter in the electricity utilization event accompanying time period, and stores the electricity meter reading value in a database; and step 3, the data analysis subsystem completes data clustering and anomaly analysis, and outputs an ammeter anomaly detection result. According to the method of the invention, the home gateway and the cloud platform work together to form the power utilization original database of each form of the electric appliance set, then the original data of the same form in the same set are screened ...
