The intelligent energy efficiency management system is developed for the characteristics and needs of energy management, and the system integrates new Internet technologies such as cloud computing, the Internet of Things, and mobile payment. By collecting all kinds of building energy consumption data and energy use system operation information, the system analyzes the energy transmission, conversion and consumption characteristics in the operation of various mechanical and electrical equipment, providing managers with visual information to help them manage energy use and control energy costs, and improve the energy use efficiency of the facility system. We are committed to creating three aspects of energy efficiency management (visualization, controllability, network); Realize the functions of remote collection, control, monitoring, management, and interconnection of equipment and system information for energy metering equipment such as water, electricity, gas, and cold/heat. Through accurate data analysis, real-time monitoring and real-time control of the system achieve energy saving, emission reduction, efficiency and other purposes. The intelligent energy efficiency system is based on energy metering equipment, data acquisition equipment is used for data acquisition and data is transmitted to the control terminal through wireless (WIFI/PF/GPRS) or wired (485, TCP/IP) network, and then the control terminal uploads the data to the data center. Thus, the data collection, analysis, control and management functions of each measuring equipment (electricity meter, hot compress, gas meter, flow meter, etc.) can be realized. The uniqueness of the system is that we can flexibly adopt a more suitable communication scheme according to the user's field environment, so that users can achieve energy control at a lower cost. System functions: Payment collection: PC charges, mobile phone charges, local and remote charges are not wrong; Instrument management: unified management of the instrument, including various parameters of the instrument management; Communication management of the acquisition controller: manages all parameters of the acquisition controller in a unified manner. Instrument data acquisition: can realize the combination of automatic acquisition and manual data acquisition mode; Instrument equipment on-off: according to customer needs, different on-off controls can be collected for different instruments; Instrument status monitoring: real-time instrument status monitoring function, through the large screen chart, monitor all instrument status; Post-stage circuit protection: the total load of the post-stage electricity can be stepless set and changed, such as 3000W, 3001W, etc., more than the total load cut off the power supply; Load identification: individual electrical power stepless setting, resistance, capacitance, inductive judgment, non-required load access, automatic power cut; Energy consumption data analysis: Generate a variety of graphs, visually display the energy consumption of the equipment, and provide energy consumption analysis; SMS reminder: the balance can be set, when the balance is insufficient, the system automatically sends SMS notification to the user; Report output: all kinds of reports and bills production and printing;
