The Energy Management Cloud Platform relies on core technologies such as cloud computing, big data, and the Internet of Things (IoT) to build an integrated architecture of "intelligent devices-edge devices-cloud platform". It realizes real-time data collection, intelligent analysis, visual display, and dynamic optimization of on-site energy equipment (such as electricity, water, gas, heat, etc.) for users. Through online energy consumption monitoring and dynamic analysis, it helps users accurately grasp the distribution and trends of energy consumption, tap energy-saving potential, reduce operating costs, and improve energy management efficiency and decision-making scientificity. The solution is suitable for energy consumption data collection and monitoring in shopping mall,building, campus, hospital, and factories.
