Power equipment data security monitoring system and method based on Internet of Things

The invention discloses a power equipment data safety monitoring system and method based on the Internet of Things, and belongs to the technical field of safety monitoring. The method comprises the following steps: collecting equipment data of a fault during working of power equipment in history, analyzing the equipment data, and extracting feature data reflecting the equipment fault; calculating a fault threshold value used for judging whether the power equipment breaks down or not according to the characteristic data when the power equipment breaks down in the historical working process; collecting all environmental data when the power equipment breaks down in the history, searching credible parameters having an influence relationship with the feature data, and calculating a credibility threshold value of the equipment fault; collecting real-time characteristic data, judging whether the power equipment breaks down or not by using a fault threshold value, and sending out fault early warning; and calculating
