Introduction: In order to promote energy conservation in the whole society, improve energy utilization efficiency, protect and improve the environment, accelerate the construction of a conservation-oriented society, and promote comprehensive, coordinated and sustainable economic and social development, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, the Ministry of Industry and Information Technology, and relevant local government departments have successively formulated Guiding documents for industrial energy consumption statistics and energy conservation work, such as "Technical Guidelines for State Office Buildings and Large-scale Public Buildings Energy Consumption Detection System", "Guiding Opinions on Doing a Good Job in Industrial Power Demand Side Management", etc. Relying on its own products and in combination with industry standards and specifications, Ankerui provides a series of perfect power management systems for the power demand side of smart grids, such as the company's internal power collection management system, prepaid power sales management system, and energy consumption monitoring management system. System solutions to sort out the trend of energy consumption and build an energy metering system for users.
Building energy consumption sub-measurement, industrial enterprise power monitoring and management, commercial real estate power sales management, college dormitory power management and other systems are composed of three layers: the central management layer, the network communication layer, and the field equipment layer.
Center management
It is mainly composed of various servers such as collection server, application server, database server, etc. The main function is to receive all kinds of energy consumption data uploaded by the communication network layer, correctly parse, process and store it in the database. After receiving the data access request from the client, the application server obtains the data from the database and sends it to the client after processing. At the same time, the system can also upload data to the upper-level data center according to the requirements of the energy consumption sub-item monitoring system of each province and city.
network transport layer
It is mainly composed of serial port server, intelligent communication gateway or data collector, communication manager, ring network switch and other equipment.
Field device layer
It is mainly composed of various intelligent instruments such as electric energy meter, water meter, gas meter, cold and heat meter, etc. The instruments can be centrally installed in the comprehensive energy consumption metering box or distributed in the equipment control cabinet, and connected through the RS-485 bus. Data collector, communication management machine, serial port server, etc.
Electric energy sub-item metering system
The system can count the energy consumption of electricity, water, gas, central heating, central cooling and other energy consumption by different categories of buildings according to the year of use, and automatically convert them into the corresponding standard coal consumption, thus reflecting the energy consumption of each category of the building in that year. energy and overall energy consumption. The system displays the consumption trends of various types of energy consumption in curve graphs, so that the owner can intuitively grasp the energy consumption situation in real time.
Comprehensive energy consumption analysis
The system can reflect the comparison of the overall energy consumption of the building today and the same period of yesterday, the same period of the current month and the same period of the previous month, and the same period of the current year and the same period of the previous year, and display the energy consumption of the building in the past 48 hours, 1 month, 12 months and 3 years Trends, comparative analysis of energy consumption in the current year, and a pie chart of energy consumption by item in the current month. It is convenient for the owner to compare and analyze the trend of energy consumption, judge the trend of energy consumption, adjust the equipment operation plan in time, and save energy consumption.
Year-on-year analysis
The system selects and sets energy consumption metering points according to the distribution of building energy consumption, so that the energy consumption monitoring system can cover the entire building. The system user can retrieve the energy consumption statistics report of each energy consumption node of the building through the relevant interface, so as to reduce the "running, running, dripping, leaking" and measurement errors of energy consumption.
Energy consumption statistics report
The system divides the power consumption of buildings into lighting sockets, air conditioners, power and special power consumption according to the collection guidelines for energy consumption data by category and item in the housing and construction department. Make statistics to show the energy consumption of the area in the form of reports and bar graphs of the same period and the chain ratio.
