Problems solved by technology

The manual inspection operation method is not comprehensive enough to monitor the equipment in the substation. On the other hand, the judgment and risk assessment of the operation status of each equipment in the substation may lead to large deviations based on the personal experience of the inspectors, and there are huge obstacles in the interconnection of information.
[0004] Taking infrared temperature measurement as an example, the existing software can only display the high-temperature points in the monitoring image, and cannot automatically locate the high-temperature fault area by merging with the visible light image, nor can it automatically identify the fault type, and the monitoring data cannot be uploaded in real time and compared with historical data. The image and video monitoring system in the substation mainly uploads the monitored data to the data center. This method cannot automatically identify useful data from the massive database, which brings great difficulties to the staff for data screening, analysis and processing. heavy workload
In addition, a large amount of image data generated by manual inspection cannot be classified and marked in time, which brings great inconvenience to later analysis and archiving
