Application Of Automatic Control System In The Building Of The Green Energy

The lack of energy and enhance the awareness of environmental protection today, vigorously develop renewable energy building is an important strategy to solve the problem. The so-called renewable energy, usually refers to the pollution of the environment, inexhaustible, be inexhaustible, and can recycle energy, including solar energy, wind energy, geothermal energy, hydropower, biomass energy and tide energy, we can call them green energy. Modern intelligent architecture to continuous development, keep pace with the times, and must be the organic combination of green energy. Today, promote the construction to the development of green, energy-saving, intelligent direction, is a general trend to realize the sustainable development of construction industry. Current, zero energy buildings become the future trend of the application of renewable energy in building technology.In order to study how to achieve zero energy consumption in the green energy building, this paper aims at the research of energy types, equipment design and construction of green energy in the building automatic control system and the energy distribution of several aspects of. The main work is as follows:(1) Species analysis research involving green energy building in the green energy.Green energy building in the green energy can be divided into electric energy and heat energy of two categories. Electric energy is mainly composed of photovoltaic power generation, wind power generation, the micro CCHP system to provide these green energy. Heat is mainly composed of a water source heat energy, ground source geothermal and solar energy systems such as poly these green energy to provide.(2) The development of automatic control system for real-time monitoring and management of green energy building equipment.The system is a research and development to the actual demand of green energy building, made of soft and hardware design in the system. The hardware of this system’s main modules including PC PC, center access machine Master, router, control unit DDC(Direct Digital Controller) and the data acquisition control unit. The system software uses front visual programming tool Delphi6.0 to implement system monitoring, communication management, data processing, control commands, dynamic display and other functions, the background database using SQL database. The development of the system monitoring program, communication program and control program, completed the hardware circuit design, the realization of each part of the control function, has a strong practical.(3) The rational deployment of various energy sources of green energy building, implementation of various complementary energy.Through the automatic control system to control various devices for green energy building, various state energy can be used to obtain various equipment conveniently, thus the calculation of the amount of all kinds of energy use, detailed analysis of the thermal energy and green energy building energy use. When the heat energy is insufficient by electric energy to supplement; when the heat energy is excessive, the excess energy into electric energy; when the electric energy excess is stored in a storage battery etc.. The entire green energy building equipment implementation does not depend on external power supply, through a variety of green energy to meet the energy needs of all experimental building, and ultimately to achieve zero energy consumption.
