Public building energy consumption data acquisition online monitoring system software development

With the development of my country’s economy and society and the increasing pressure on environmental resources, the problem of high energy consumption in large public buildings has become increasingly prominent, and the situation of energy conservation and emission reduction is severe. It is urgent to do a good job of online monitoring of energy consumption in large public buildings.
However, in the current national statistical system, it is difficult to obtain relatively accurate data on the energy consumption of public buildings. As a result, the competent authorities at all levels are not effective when formulating energy-saving and emission-reduction targets and preparing relevant development plans, policies, regulations, and standards. Of building energy consumption data. Therefore, the development and construction of an online energy consumption monitoring system is particularly important.
1. Energy consumption monitoring system
1.1 Carry out the basic work of energy consumption monitoring.
According to the relevant documents of the Ministry of Housing and Urban-Rural Development, energy consumption statistics have been carried out since 2008, with a statistical area of ​​approximately 5.513 million square meters.
Through the analysis of energy consumption statistics and results, we have gained a preliminary understanding of the energy consumption characteristics of buildings, and found that the energy consumption of large public buildings is in the forefront of the surveyed buildings, and these buildings need to be provided all year round. Illuminated and air-conditioned building.
1.2 Status quo of energy consumption monitoring at home and abroad.
(1) In 1976, the United Kingdom began to conduct energy consumption surveys on buildings, and established a detailed energy consumption database including building types and air-conditioning forms. The National Bureau of Standards was also responsible for the contemporary United States. Statistics of building energy consumption. At present, the United States has established a statistical database of building energy consumption. Currently, the most widely used databases that collect a large number of buildings include CBECS of the Department of Energy (DOE) and CEUS of California.
(2) my country currently does not have a complete monitoring network to analyze and count building energy consumption. However, under the background that the country is actively constructing a building energy consumption monitoring platform, my country has launched a series of work in some first-tier cities such as Beijing and Shenzhen, and has achieved remarkable results.
1.3 Research and development of energy consumption monitoring system.
1.3.1 Application technology.
In the selection of energy consumption monitoring system, the current mainstream B/S architecture is adopted, and the development environment is WEB access mode energy consumption monitoring software. The system is widely used due to its easy deployment and high compatibility. . The database adopts the database software based on Microsoft SQL2008 Enterprise Chinese Edition. The database supports network multi-point connection, can store and process massive data, and the system performance is efficient, safe and stable.
1.3.2 Realization of functions.
(1) The energy consumption monitoring system collects, processes and analyzes the classified energy consumption of eight types of buildings. Energy consumption data mainly includes 13 energy consumption items including electricity, central heating, gas, and water. The energy consumption monitoring system is mainly used to count and analyze the classified energy consumption of various buildings, and can realize the classified energy consumption comparison between administrative regions, classified buildings, and arbitrary buildings.
(2) Energy consumption monitoring system mainly includes: building basic information management module, building data collection and transmission module, energy consumption data processing module, energy consumption data statistics module, energy consumption data analysis module, energy consumption data publicity Modules, etc.
2. Energy management (1) Help building users to transform the energy system from extensive management to fine, scientific management. Under the original energy management method, generally only the monthly power consumption and monthly cost of the total incoming line of the building power supply are recorded. Even if the total daily power consumption can be recorded, it is impossible to record the power consumption and real-time current data of all lines . The energy consumption monitoring platform can monitor most of the operating energy consumption data in real time, so that building users can grasp the operation of the energy system in real time and make reasonable adjustment strategies for the operation. (2) Help building users realize the diagnosis of low-efficiency and quasi-fault operation of the energy system. Improve the operational reliability of the energy system. (3) Help users realize the energy management and energy report upload required by national energy statistics, and improve the management level of owners. (4) Continuously provide building users with building energy consumption, especially basic data for optimized operation of HVAC systems. The air-conditioning system is the main component of power consumption. The energy-saving renovation of buildings is also based on the air-conditioning system. On the premise of having a large amount of energy consumption monitoring data, an effective air-conditioning system optimization operation report is proposed to provide technical support for the later energy-saving renovation. (5) Encourage energy use units to strengthen energy use management, formulate corresponding management systems, and consciously strive to improve energy conservation efficiency to achieve the goal of energy conservation. (6) It is beneficial to quantitatively evaluate the effect of energy-saving renovation. Through the use of energy monitoring platform system software, a large amount of real energy consumption data can be collected, and data analysis can truly evaluate the energy consumption changes of buildings or systems before and after the energy-saving renovation. In the face of increasingly serious climate change issues, Yuanzhongrui Technology adheres to the mission of “Environmental Protection, Energy Conservation, Love the Earth”, and takes the lead in actively promoting energy-saving renovations in various plants within the group. Provide online energy consumption monitoring system for industrial enterprises. Under the strategic layout of electrical intelligence and energy management, Yuanzhongrui Technology has developed into a development service provider with a strong software research and development team in China.
