The existing distribution line fault monitoring equipment can only realize fault alarm after the monitored line fails, and cannot realize fault early warning before the monitored line fails.
Based on the above research, please refer to fig. 1, an embodiment of the present application provides a distribution line fault monitoring apparatus 100 to effectively prevent a monitored line from being damaged by an external force by implementing a fault early warning before the monitored line may have a fault, so as to reduce the fault occurrence rate of the monitored line, the distribution line fault monitoring apparatus includes a processor 110, a distance detection device 120, a fault detection device 130, and an alarm device 140.

During the operation of the distribution line fault monitoring apparatus, the radar detector 121 may transmit a radio wave to the first object at a preset time interval for each object within the target space range, for example, the first object within the target space range, obtain, for a radio wave transmitted at each transmission time, for example, a radio wave transmitted at the first transmission time, after the return of the radio wave, a time interval between the return time of the radio wave and the first transmission time as a round trip time of the radio wave, and obtain, as the first distance interval, a distance interval between the distribution line fault monitoring apparatus 100 and the first object at the first transmission time from the round trip time and a transmission speed of the radio wave. Thereafter, the separation distance between the distribution line fault monitoring apparatus 100 and the first object at the second transmission time, which is the next time to the first transmission time, is continuously obtained as the second separation distance.
