Description

A smart monitoring system for overhead transmission lines Technical Field

[0001] This invention relates to the field of circuit maintenance technology, and in particular to an intelligent monitoring system for overhead transmission lines. Background Technology

[0002] Existing monitoring technologies typically employ interval shooting or loop recording to achieve monitoring functions. These methods suffer from poor event capture capabilities, high power consumption, low timeliness, and a lack of fault alarm capabilities. In the event of sudden faults, delayed information detection often leads to untimely repairs and prolonged short-circuit faults. Current technologies also lack specific fault identification capabilities for transmission lines, resulting in false alarms and increasing the workload of patrol personnel. Furthermore, existing devices cannot accurately monitor line icing and cannot provide early warnings of the risks associated with icing.

The capture camera captures images of sudden events. The collected data is processed by the first image processor in the first computing module, and the first AI computing chip identifies special objects in the image and determines whether an alarm is needed.

[0077] The advantages of this capture device compared to traditional monitoring technologies are as follows: Traditional monitoring technologies generally use interval shooting or loop recording, resulting in poor event capture capabilities, high power consumption, low timeliness, and lack of fault alarm capabilities. In the event of a sudden fault, information is often detected late, leading to untimely repairs and potentially causing power outages. This device provides 24 / 7 online monitoring of transmission lines, enabling the capture of instantaneous fault flashovers, data collection and analysis of transmission corridors, channel environments, mechanical intrusion, and external damage. Data is then uploaded and received wirelessly, allowing back-end management personnel to understand the real-time situation and promptly control and resolve potential transmission line faults.

[0078] The advantage of the icing detection device is that it has good anti-power frequency electromagnetic interference performance, can complete accurate and complete data acquisition in ultra-high voltage electromagnetic environment, and accurately control the front-end equipment. Since the detection device often works in harsh weather environment, it should be designed as a self-powered type, that is, it uses induction to obtain working power from the monitored line, which is maintenance-free and reliable in operation.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
