The remote intelligent inspection system is a critical component of modern smart grid construction and one of the core applications of "smart substation". Leveraging IoT technology, AI algorithms, image recognition & analysis, inspection robots, HD video surveillance, infrared thermal imaging, and multi-sensor fusion, it assists or replaces traditional manual power inspections to achieve 24/7, omnidirectional, automated, and intelligent monitoring of substation equipment status and operating environment, enabling real-time analysis and early warning for abnormalities. It significantly enhances substation operation safety, reliability, cost-efficiency, and smartness, serving as vital infrastructure for modern smart grid development and reliable power supply.
