In order to realize the background of large-scale data analysis and control of power equipment development based on Internet of Things, a design idea of power equipment management system and large-scale data system analysis is proposed. This paper firstly introduces the design of power industry control and control system application. The open source electronic information service platform includes customer and interactive terminal. Designing an architecture design system. Using mathematic model and analytic method to analyze, analyze and determine the major data of power supply enterprise. From the conclusion of data analysis, with the system management theory and scientific management method, the inherent regularity of enterprise management and management, the operating process and management result are revealed, which widens the evaluation in the area of energy service, and there is plenty of room for improvement.
