HC network security information can automatically lift the curtain can "read" the system automatically set the advance work calendar temperature and humidity of the room, when the storage battery system start low price, depending on the concentration of carbon dioxide indoor day automatically adjusted according to light conditions Ventilation system... This is a beautiful sight of smart buildings in the future.
Building automation systems are one of the main components of smart buildings. The intelligent building realizes the comprehensive monitoring and management of the equipment and building environment in the building (group) through the building automation system, creating a comfortable, safe, economical, efficient and convenient working and living environment for the users of the building, and optimizing the operation of the equipment and Management, reducing operating expenses. The building automation system involves equipment, systems such as electric power, lighting, air conditioning, ventilation, water supply and drainage, disaster prevention, safety precaution, garage management, etc. It is the most extensive subsystem in intelligent building, with the largest design task and engineering construction. Its design level and engineering construction quality have a direct impact on the realization of intelligent building functions. The building automation system monitoring system consists of several components with different functions.
First, air conditioning monitoring
The building automation monitoring system can supervise the air conditioning system in the building, and combine the chilled water flow rate and the supply/return water temperature to calculate the cooling load of the air conditioning system, which is displayed on the CRT monitor of the automation system. Combined with the cold load, the group control equipment with the air conditioning freezer unit is used to determine the number of start and stop of the chiller, thereby achieving energy saving. Automatically control and measure the differential pressure of the chilled water system supply/return water mains to ensure that the system is at a normal differential pressure value. The interlocking control between the chilled water pump and the cooling water pump enables the standby water pump to be automatically put into use if there is a problem with one chilled water pump. The monitoring of the air conditioning system mainly includes air conditioner cabinets, exhaust fans, fan coils, cooling chilled water pumps, and water collectors.
Second, the water supply and drainage system monitoring
The intelligent monitoring system in the intelligent building can clearly define the operation of the water supply and drainage system water pump in the building, and clearly record the time, water quantity and pressure value of the water supply and drainage equipment. If the water pump is abnormal, the intelligent building automation system can Start the standby pump under interlock control and put it into operation. The monitoring of the water supply and drainage system in the building mainly includes the following parts, such as fire protection, domestic water pump, sewage pump, underground water pool, sewage pool and monitoring system for water supply and drainage.
Third, monitoring the power supply and distribution system
The power monitoring system can be set up in the building of the intelligent building, so that the data collection of the power supply of the community is the same, and the modularization of the hardware system of the pen is realized through the power monitoring system, so that the system is more reliable and safe. Expenditure to reduce cable and engineering construction costs can be done by bus. To scientifically analyze and analyze the conformity of the whole community, it is necessary to monitor the switch quantity and analog quantity of lighting, air conditioning and power supply of the whole building. In this case, the lighting of the control layer and the air conditioning distribution box can be mutually invested. If an unexpected incoming power supply has an unexpected problem, you can cut a lighting task for a closed bus into another closed bus. Setting up the power monitoring system and carrying out control work can make the power supply more secure and reliable, and also keep the power supply level at a high level, reducing the task and difficulty of property management.
If you use a power monitoring system to achieve energy savings, the cost will increase significantly. In order to make the power distribution system operate normally and safely and ensure the assessment of power distribution, the control center needs to scientifically monitor and record the actual operation of the power distribution system. Intelligent building automation monitoring systems also require the installation of CCTV systems, patrol systems, and access control systems.
Fourth, intelligent lighting system
In the current development of construction engineering, intelligent lighting technology has become the main content. Intelligent lighting has always been neglected, and most buildings still use traditional lighting control methods. Some intelligent buildings monitor the lighting through an automated system to illuminate the area and achieve a timed switch. This kind of intelligent lighting system generally controls 2 layers per layer, combined with the illumination to determine whether to open 1 or 2 channels, and at the same time, the switch lighting can realize the power consumption.
