With the development of urban modernization, the intelligentization of buildings, especially the intelligent systems of public buildings, covers more and more content. The starting point of engineering intelligent system engineering design should be to configure various functional systems with architecture as People provide a reasonable investment, efficient, comfortable and convenient environment to meet the needs of today's modern architecture. The modern business building is based on a high degree of intelligence, and the building automation system is the embodiment of modern building intelligence. The building automation system is a comprehensive system for the purpose of centralized monitoring, control and management of equipment or systems such as cold and heat sources, air conditioning, ventilation, water supply and drainage, power distribution, lighting, and elevators. In order to build an excellent building equipment monitoring system, three elements of the system were considered. One is to determine the number of controller I/O points and points that serve the equipment or subsystems, and to confirm the interface technology processing of I/O points; the second is field instruments, meters, sensors, transmitters, and actuators. The correct selection and configuration of components; the third is the configuration of the central operating station and communication network.
The building equipment monitoring system is a distributed control system based on the distributed control theory in modern control theory. It connects the intelligent units distributed in each monitoring site through a central computer to form an advanced and comprehensive integrated monitoring system. Centralized monitoring and control of the electromechanical equipment of the entire building to ensure that the equipment operates in an optimal state, providing a comfortable, efficient, safe and energy-saving environment for the building. Therefore, not only the building automation control system is required to be reliable, but also open, flexible and economical.
First, the design basis
The total construction area of ​​a building is xxxxxxm2, the building height is xxxm, the building layer is xx floors above ground, and the underground x layer is a comprehensive intelligent building integrating hotel, office, business, entertainment and hotel. Building intelligent systems include: Building Automation System (BA), Security System (SAS), Integrated Cabling System (GCS), Automatic Fire Alarm System (FAS), Vehicle Import and Export Management System, Telephone Communication System, Public Address System, Cable TV system (CATV), weak power supply and grounding system.

Second, the specific design of each subsystem
1. Building Automation System (BA)
According to the statistics of Honeywell Corporation of the United States, the total investment of BA systems in large modern buildings generally accounts for about 1--2% of the total investment in buildings. After the BA system is put into operation, it takes only 2 to 4 years to recover the investment. Because in the BAS, through the intelligent management and optimal control of the air conditioning system and the control of intelligent lighting , energy can be effectively saved, thus bringing direct economic benefits to the owners. Since the automatic monitoring and management of the equipment is realized, some engineering personnel and management personnel can be reduced, a large amount of personnel expenses are saved for the owner, and some disadvantages of manual operation and management are overcome, and some accidents and equipment damage can be reduced. Bring potential economic benefits to the owners. At the same time, due to the realization of the setting control of the temperature of the end of the air conditioner, the environmental comfort can be improved, and the building can improve the competitiveness in the property market, bringing indirect economic benefits to the owner.
2. Security System (SAS)
Adopting Skynet integrated system, the traditional TV monitoring system, anti-theft alarm system, patrol system, entrance and exit management system and other independent systems are integrated into an organic whole. The device configuration is based on “hardware linkage and software linkage. The principle of "distributed control, centralized management" in the operation to increase the reliability of the system. The entire security system adopts centralized computer management, taking into account the characteristics of TV monitoring, burglar alarm, access control, patrol and other systems to achieve the overall defense of the building.
Vinyl Pool Lights are recessed pool lights,small and exquisite, sealed and waterproof. At the same time, Vinyl Pool Light is an aluminum Lamp body, which has the advantages of corrosion resistance and impact resistance.And a toughened glass mask is used, which has high hardness, high pressure resistance and good light transmission. In addition, it uses LED lamp beads, high lumen, high brightness, and long light source life, which can be better used for swimming pools, aquariums, etc.
