AI Technical Summary
The accuracy of remote reading and recording of transformer oil level gauges in the existing technology is low, mainly because video compression causes the scale and digital edges of the oil level gauge to be blurred, which affects the accuracy of reading and recording.
On the edge computing device side of the substation, the transformer oil level gauge area in the captured video is identified and the reading information is extracted. Semantic coding technology is used to generate the first bit stream data transmission from the high-confidence reading information, and local high-fidelity coding is performed in the low-confidence scenario to ensure that the monitoring center receives high-fidelity oil level readings.
It significantly improves the accuracy of remote reading of transformer oil level gauges, achieving reliable remote reading with high precision, low latency, and low bandwidth dependence, avoiding the destruction of key details by video compression, and ensuring the accuracy of oil level readings.
