Shulou(Shulou.com)06/03 Report--

With the economic and social development of our country and the increasing pressure of environmental resources, the problem of high energy consumption of large-scale public buildings has become increasingly prominent, and the situation of energy saving and emission reduction is grim. It is urgent to do a good job in on-line monitoring of energy consumption of large-scale public buildings.

However, in the current national statistical system, it is difficult to obtain more accurate energy consumption data of public buildings, resulting in the competent departments at all levels in the formulation of energy conservation and emission reduction targets, the preparation of relevant development plans, policies, regulations and standards, lack of effective building energy consumption data. Therefore, the development and construction of energy consumption online monitoring system is particularly important.

1. Energy consumption monitoring system

1.1 carry out basic work on energy consumption monitoring.

According to the relevant documents of the Ministry of Housing and Construction, energy consumption statistics have been carried out since 2008, with a statistical area of about 5.513 million square meters.

Through the statistics of energy consumption and the analysis of the results, we get a preliminary understanding of the characteristics of energy use of buildings. It is found that the energy consumption of large-scale public buildings is in the forefront of the buildings investigated, and these buildings are buildings that need to provide lighting and air conditioning all the year round.

1.2 current situation of energy consumption monitoring at home and abroad.

The main results are as follows: (1) in 1976, Britain began to investigate the energy consumption of buildings, and built a detailed energy consumption database, including building types and air-conditioning forms, etc., and the National Bureau of Standards was also responsible for the statistics of building energy consumption in the United States at the same time. At present, the building energy consumption statistics database has been established in the United States. at present, the widely used databases that collect a large number of buildings are CBECS of the Department of Energy (DOE) and CEUS of California.

(2) at present, there is not a perfect monitoring network to analyze the building energy consumption in our country. However, under the background of the active construction of building energy consumption monitoring platform, China has carried out a series of work in Beijing, Shenzhen and other first-tier cities, and has made remarkable achievements.

1.3 Research and development of energy consumption monitoring system.

1.3.1 Applied technology.

In the selection of energy consumption monitoring system, it adopts the mainstream Bhammer S architecture and the development environment is WEB access energy consumption monitoring software. the system is widely used because of its easy deployment and high compatibility. The database adopts the database software based on Microsoft SQL2008 enterprise Chinese version, which supports network multi-point connection, can store and process massive data, and the performance of the system is efficient, safe and stable.

1.3.2 implement the function.

The main contents are as follows: (1) the energy consumption monitoring system collects, processes and analyzes the itemized energy consumption of eight types of buildings. Energy consumption data mainly include 13 items of energy consumption, such as electricity, central heating, gas, water and so on. The energy consumption monitoring system is mainly used to count and analyze the classified itemized energy consumption of all kinds of buildings, and can realize the classified itemized energy consumption comparison between administrative regions, classified buildings, arbitrary buildings and so on.

(2) Energy consumption monitoring system mainly includes: building basic information management module, building data acquisition and transmission module, energy consumption data processing module, energy consumption data statistics module, energy consumption data analysis module, energy consumption data publicity module and so on.

two。 Energy management

(1) to help building users change the energy system from extensive management to fine and scientific management. Under the original energy management mode, only the monthly power consumption and monthly cost of the total incoming line of the building power supply are generally recorded, and 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) to help building users to diagnose the inefficient and quasi-fault operation of the energy system. Improve the operation reliability of the energy system.

(3) to help users to achieve the national energy statistics requirements of energy management and energy reports upload, improve the management level of owners.

(4) continuously provide building energy consumption for building users, especially the basic data of optimal operation of HVAC system. The air-conditioning system is the main component of power consumption, and the building energy-saving transformation is also based on the air-conditioning system. On the premise of having a large number of energy consumption monitoring data, an effective report on the optimal operation of the air-conditioning system is put forward to provide technical support for the later energy-saving transformation.

(5) urge energy-using units to strengthen energy management, formulate corresponding management systems, and consciously strive to improve energy-saving efficiency so as to achieve the purpose of saving energy.

(6) it is helpful to quantitatively evaluate the effect of energy-saving transformation, a large number of real energy consumption data can be collected through the use of energy consumption monitoring platform system software, and data analysis can truly evaluate the energy consumption changes of buildings or systems before and after energy-saving transformation.

In the face of the increasingly serious issue of climate change, Yuanzhongrui Science and Technology, adhering to the mission of "environmental protection, energy saving and loving the earth", has taken the lead in actively promoting energy-saving transformation in all factories within the group. Provide online energy consumption monitoring system for industrial enterprises. Under the strategic layout in the field of electrical intelligence and energy management, Yuanzhongrui Science and Technology has developed into a domestic development service provider with a strong software research and development team.
