These devices are scattered in every corner of the building, manual management very difficult. Building automation sy
5、stem for unified management of multiple systems to improve equipment management accuracy. Building a lot of systems and equipment, management personnel for maintenance, overhaul, a great amount of labor. Building automation system can automatically diagnose equipment operating conditions, equipment

Building automation system to adjust the building to various electrical and mechanical equipment operating conditions, close does not need to run the equipment, sa

Statistical data show that the relevant institutions, 1 million square meters of building automation system works with an annual saving of about 15% 20% of the air conditioning running costs. System intelligence is not highThe current building automation systems for electrical an
8、d mechanical equipment management is the basic management of the equipment itself, there is little basis for building designers, and the user needs, develop solutions for the optimization of the system intelligence is not high, system turn-rate is very low. Cause the system intelligence is not high,
9、 there are many reasons for the low opening, but the people through analysis, we can find a lot of common problems. First, the building automation system involves relatively wide range of knowledge, the system is relatively complex, the requirements of design engineers are also high. Most of the tim
10、e control of the company to undertake the project, first proposed by professional engineers, equipment requirements of the process parameters, and then by a professional engineer to design the control system. Although this approach can meet the general requirements of users, but because of building
11、management division to manage multiple systems, difficult to achieve optimal operation of equipment. Overall energy saving building not the ideal. Secondly, some building automation systems management software intelligence is not high, stay in the basic management of devices, without considering the
12、 interconnection of the subsystems, workflow design is not detailed, to the future upgrades, maintenance inconvenience. Finally, the building automation system is difficult with other construction equipment for data communications. To some extent hampered the opening of the system and equipment for
13、optimal management. Hardware and software design focus on smart, stable Building automation system for emerging issues, designers should pay attention to the system software on the intuitive, intelligent and stable. Management control of the buildings are three-dimensional, in the user interface on

If conditions allow, can be simulated by a three-dimensional modeling of buildings, to give managers a more realistic system operating environment, to help them better manage the entire building. The quality of t
15、he software building automation systems affect operating results, therefore, the system software not only to control the subsystems of equipment and management should also be operational status of each subsystem to optimize and improve the system efficiency.System software is the core of the whole s
16、ystem of the brain, security can not be ignored. Designers should be from the network security, data security, system security, operational safety and operational aspects, to improve system stability and security. Systems engineers in the design of electrical control box should be the beginning of suppliers and other construction equipment provider interface requirements put forward, such as the
