Intelligent building management system?

Intelligent building control system refers to a system that uses computers to automatically control all mechanical and electrical facilities in a building.

Intelligent building mainly monitors and manages the mechanical and electrical equipment in the building. With the development of technology, the concept of intelligent building continues to expand, including not only the monitoring, control and management of traditional mechanical and electrical equipment, but also intelligent lighting, floor and room automation, energy management and so on.

Intelligent building plays an important role in building energy saving. Especially after the application of new technology, the subsystems in the whole building can be organically integrated into a whole, which can effectively reduce the energy consumption of equipment. For example, the central air conditioning system and lighting system can effectively manage and control the energy consumption of these two buildings, and use them on demand while ensuring energy conservation, which can significantly improve the comfort of building managers, enhance user experience, reduce energy consumption, and make the operation and maintenance of building energy consumption sustainable.

The system covers a wide range and mainly includes the following subsystems. This case introduces the intelligent building visual monitoring system:

Power transformation and distribution system: Safe and reliable power supply is a prerequisite for the operation of intelligent building policy. In addition to meeting the functional requirements of relay protection and automatic input of standby power supply, power system must also monitor the state of switches and transformers, current, voltage, active power and reactive power of the system, so as to realize comprehensive energy management.

By combining the distribution line with the building model, the trend of the distribution line can be viewed intuitively, and the power data can be monitored by IOT equipment. When there is a power failure, it can send out an alarm signal in time to ensure the normal operation and system safety of the power system.

Lighting system: Lighting system consumes a lot of energy, which is second only to HVAC system in large high-rise buildings, and leads to an increase in cooling load. Intelligent lighting control should attach great importance to energy-saving work, such as turning off the lights when people walk, setting the on/off time with programs, and turning on/off the lights at any time by means of key switch, infrared, ultrasonic and microwave measurement.

In the aspect of building automation, the HT data visualization supervision platform is applied to realize the linkage between reality and three-dimensional scene by restoring the lighting equipment points in the floor and connecting the lighting control system, so that all lighting equipment states in the building can be supervised and controlled without leaving home, so as to reduce the daily lighting energy consumption and realize real intelligent lighting.

Air conditioning and cold and heat source system: under the condition of ensuring comfortable environment, reduce the energy consumption of building air conditioning system as much as possible. The main energy-saving control measures are as follows: equipment start-stop control; Energy-saving optimization control of air-conditioned refrigerator: equipment operation cycle control: power load control, refrigeration system control, etc.

In the management and control platform of smart park, the pipes and equipment of air-conditioning system can be restored and displayed, the routing of air-conditioning bridge and data such as temperature, humidity and air quality can be viewed intuitively, and the reverse control of air-conditioning equipment can be supported through three-dimensional scenes, so as to carry out real-time maintenance and troubleshooting of air-conditioning equipment, and improve the air environment quality in the park and the work efficiency of traffic managers.

Environmental monitoring and water supply and drainage system: besides air conditioning system, it is also necessary to monitor the cleanliness and hygiene of air, and then take measures such as ventilation and disinfection. Many cities in China are short of water. In addition to ensuring drinking water, we should also pay attention to the control of water reuse.

Water supply and drainage management is mainly used to monitor and manage the water supply and drainage and sewage treatment system of buildings. By combining water quality monitoring, water quantity monitoring, water leakage monitoring, water pressure monitoring and sewage treatment monitoring with three-dimensional scenes for visual display, the status data of various aspects of water supply and drainage can be known in real time, and the running status and abnormal situation of equipment can be monitored to help managers achieve the purposes of safe drinking water, resource saving and building safety.

Elevator system: large buildings are equipped with multiple groups of elevators. In order to optimize transmission, control the average utilization rate of equipment and save energy, it is necessary to realize group control by computer.

In the visualization platform of smart community, Hightopo realizes elevator animation simulation by binding the elevator operation data-driven model, and highlights the abnormal alarm equipment, which greatly increases the response efficiency of elevator fault handling and ensures the safety of personnel.

Parking management system: parking management often adopts card reading method. In the case of no charge for the internal garage, the car can enter the parking lot after being confirmed by the card reader as belonging to the system.

Restore the parking spaces and facilities in the parking lot through the three-dimensional scene, dock the parking space data in real time and simulate the restoration in the three-dimensional scene, monitor the parking space occupation in the park, and carry out vehicle management. Based on multi-dimensional data such as space, time and index, the traffic flow, type and time period analysis data of vehicles in the park are dynamically refreshed, and the daily parking space usage in the park is summarized in real time, effectively improving the traffic efficiency and parking space usage efficiency.

The three-dimensional visual monitoring system of intelligent building realizes the overall management and control function of the building complex. The principle of "distributed control" extends the "small distributed control" system of single building to the "large distributed control" system of the building complex, which makes the sensing unit (sensor layer), control unit (IP function controller and function control software of application layer), execution unit (IP function controller and field execution equipment of application layer) and feedback unit (feedback mechanism and function control software of sensing layer) of the building complex

Due to the improvement of building grade, the number of new building equipment has increased. After interconnection, by collecting, sorting and mining the operation data of these devices, combining with new technologies such as cloud computing and cloud storage, and applying big data analysis, we can find the energy consumption of the same type of buildings, which is of guiding significance for establishing various building energy efficiency standards. Through the Internet of Things technology, the intelligent and energy-saving effects of buildings can be effectively improved.

The collection and analysis of building big data makes it possible to provide building cloud services. Intelligent building system network can automatically track property data, understand the preferences of property personnel, and automatically configure lighting, HVAC, elevator and other systems. In addition, the intelligent building industry has gradually attached importance to the customer data ignored by traditional construction enterprises, and provided better service experience for customers by tracking the customer's work and rest time, consumption behavior and other data.
