Intelligent buildings mainly include security systems, computer networks, communication systems, building automation systems, etc., to a large extent to meet people's needs, electrical automation control is the function of intelligent buildings to play a technical guarantee, in the intelligent building has an irreplaceable position.
3.1 Building electrical equipment automation system installation before the development of a scientific plan
The quality of the building electrical equipment automation system directly affects not only the function of the building whether the normal operation, but also affects the environmental benefits of the building and economic benefits. Therefore, before construction, the relevant staff can not blindly follow the drawings for construction, a comprehensive understanding of the design program, timely design drawings in the shortcomings of the proposed improvements to avoid rework of the project. In addition, according to the owner's needs and interests, to develop a scientific and reasonable installation plan, in strict accordance with the operating procedures for construction, in order to meet the building itself as well as the owners of the relevant needs.
3.2 Installation of electrical equipment
The normal operation of electrical equipment is to ensure that the building electrical equipment automation system function to give full play to the premise. Electrical equipment installation and commissioning is to ensure its normal operation of the basic conditions, need to carry out the following steps: first of all, be sure to understand the entire equipment process, control processes, master the electrical equipment to use a variety of instruments. Secondly, carefully study the design and construction drawings. Finally, according to the design drawings of the electrical equipment inside the wiring to understand clearly, then you can carry out the actual wiring of the equipment. After all the equipment commissioning is completed, then its installation construction. When installing the equipment, it must be installed in strict accordance with the installation requirements and specifications of the equipment. Here it is important to note that before wiring must be calibrated, in order to determine the appearance of the equipment is intact, wiring is correct, external signals are normal on the basis of the user can begin to debug with power, before sending power, all circuit breakers to maintain the power-off state.
4 Conclusion
As we all know, the integration of the world economy, globalization is the mainstream of economic development in today's world, in order to enhance China's comprehensive national strength, we must vigorously develop the construction industry as one of the pillar industries. However, due to the gradual increase in people's requirements for building design, the traditional building has been unable to meet the needs of the people, so the intelligent building appeared in people's vision, which brings high quality of life enjoyment, so that people are yearning for. The establishment of intelligent buildings can not be separated from the support of electrical automation control technology. In other words, the emergence of intelligent buildings, to the development of electrical automation engineering has brought a very good platform, is widely used in many fields and professions, its technology has a fast update speed, complexity and other characteristics, therefore, the need for relevant staff to continue to learn and accumulate experience, and keep abreast of the times.
