According to statistics, from 2011 to 2016, there were 524,000 electrical fires in China, resulting in 3,261 deaths, 2,063 injuries, and direct economic losses of more than 9.2 billion RMB, accounting for more than 30% of the total national fire and casualties; There were 17 major electrical fires, accounting for 70% of the total number of major fires. These accidents have exposed outstanding problems in the production quality, circulation and sales of electrical products, electrical design and construction of electrical engineering, electrical products and their use, maintenance and management.

In reality, many production and operation units have old electrical lines, hidden dangers and concealment. Many small and micro enterprises lack professional electricians, and cannot visually discover electrical hazards. Traditional detection methods cannot timely investigate various hidden dangers and other problems, which make it difficult to implement monitoring and warning of electrical fires.
