Abstract:To investigate the energy consumption in different areas of the campus, the energy monitoring platform has been designed. In the process of the implementation of energy-saving regulation on campus, by using B/S, Ajax, MYSQL and PHP language, the power data is displayed to the user in the WEB page by a variety of figures.at the same time, users can master real-time data of the entire campus building energy consumption through a WEB page management, which turns distributed monitoring and centralized management for the campus energy system into reality.The emphasis is put on analyzing the key techniques during the development of the system.The development and operation practice show that the adoption of these techniques significantly enhances the monitoring efficiency of the campus power system.
