1、Changes in planning and design are the key to low-carbon smart buildings

Buildings to be constructed in important cities in my country today should be planned and designed with a future-oriented attitude, guided by the goal of "dual carbon strategy", and according to the requirements of carbon peak cities. In this way, we must conform to the development of science and technology, and cannot restrict or limit innovative thinking and practice with the backward technological framework. Specifically, the "strong and weak electricity" of traditional buildings, isolated fire control, outdated integrated wiring communication systems, and strong electricity relying on cable laying methods, etc., do not meet the requirements of smart buildings in the Internet of Things era. Suboptimal during both construction and operation phases, creating significant barriers to low carbon goals for the building life cycle.

It integrates the relevant functions of the strong and weak current system and fire control and other related functions, and meets the modern Internet of Things standard. The intelligent project with the overall intelligent power distribution system as the core can also save the initial investment and is a world-class high-tech innovation with high cost performance. solution.

2.The core of the overall intelligent power distribution system is a digital and intelligent complete closed-loop constructed by "flexible busbar + IoT terminal protection controller + behavior sensing sensor".

The core of low-carbon buildings is the Internet of Things construction of the five major energy systems of water, electricity, heating and cooling. The core of which is that the power distribution system must enter the "flexible bus + IoT terminal protection controller + behavior sensing sensor", and no longer integrate the power system. And the information system is divided into strong electricity and weak electricity, instead of dividing power distribution and integrated wiring, but entering the new infrastructure era of IoT smart buildings to realize IoT construction, that is, "smart power distribution system + optical fiber-based wireless coverage" , with the smallest space for wiring and cabling, to achieve the Internet of Things management and control of all electrical loads (including water, electricity, gas, heat, and cold control and distribution). +Intelligent closed-loop AI electrification management and control, making electricity from "invisible, untouchable" to transparent, see-through, measurable and controllable, and the safety and status of electrical loads have also achieved fundamental dynamic big data operation status in this construction, Analysis and control of the whole life cycle of health status.

3. The electrical + communication system is the core component of the building in addition to the structure.

The construction of smart power distribution + communication mode is inevitable for building development, low-carbon construction, and technological development. The arc-free relay protection AI power distribution device with innovative core technology (AC contactor-type AC zero-crossing makes excessive arc-free). ), is a major electrical technology advancement that pushes the life of the switch from ordinary contactors or air switches to 1 million times of safe electricity use. A milestone in the development of electric power equipment. At present, it has obtained reliable and trouble-free power distribution operation in various high, medium and low-grade buildings for 6 years. It has been included in the Ministry of Emergency Protection of the People's Republic of China and recommended in 2018 for innovative technology to prevent major accidents. The columns have all passed the national CQC pre-appliance compulsory certification, and the supporting intelligent control smart building cloud platform software, fire IoT cloud platform software and embedded edge computing IoT terminal software system, which have been used for many years, are the key to building smart buildings. The best product.

4. In prefabricated buildings, busbar-based power distribution + AI IoT power distribution terminals can be combined with the prefabricated steel structure design. It is also the best power distribution system that can be embedded before concrete pouring, which can greatly promote the prefabricated buildings to be more intensive, The target development of perception, integration and convenience effectively empowers the new generation of prefabricated buildings.

5. With the gradual improvement of electrification, especially the prospect of electric vehicle charging service becoming a basic service that must be added to many public buildings, the overall intelligent power distribution system is more necessary for building functions: the integration of AI power dual circuits into the building power distribution system As part of the energy optimization control, scheduling, and ADR implementation of the entire park, the power distribution security system basically meets the large-scale needs of UPS for building fire protection, IDC, and public area power consumption and power protection, on the other hand, for regional micro The load balancing of multiple transformers in the power grid and dynamic dispatching of the residual electrical capacity of multiple transformers for electric vehicle charging have long-term significance.

三、The overall intelligent power distribution system brings buildings into the era of energy big data and is a powerful tool for intelligent operation

The overall intelligent power distribution system can empower the building management and control system through the integration of energy big data and building big data, and realize self-learning, self-adaptation, and multi-program and personalized control logic through artificial intelligence algorithms, greatly refining the building. The management granularity of each space is based on the user's various needs for the building space to optimize the function. At the same time, under the guidance of the system optimization strategy, the function optimization is the premise to achieve the ultimate energy saving and achieve sustainable and considerable operational economic benefits.

The following analysis can show the implementation path of the above ideas:

1.Make all the measurement of water, electricity, heating and cooling as part of the smart building flexible power distribution IoT system, that is, real-time, online, dynamic monitoring of all ADR data, and incorporate it into the big data system;

2.Connect every lamp, every socket, every connected electrical equipment through the smart distribution IoT power distribution device to form an IoT management ADR control terminal object that echoes the "cloud platform";

3. Incorporate every water pump, every fan, every air conditioner and every thermal equipment into the building network system through the Internet of Things electrical terminal, in-depth real-time optimization analysis and dynamic control of the consumption of each watt of electricity, to achieve ultra-low carbon architecture;

4.According to the function in the building, the "sixth sense" sensor box is installed on the ceiling, and the "temperature, humidity, atmospheric pressure, smoke, pm1, pm2.5, pm10, formaldehyde, TVOC, CO2, 3D Building posture, building vibration, presence or absence of human activity, infrared measurement and control, and 16 environmental parameters are included in the big data of smart buildings; 5. Install "sensors" on the ceiling in the public areas of the building to sense whether there is a presence or absence through radar. Human activity path, so as to achieve intelligent goals such as decision-making of lighting on and off, air conditioning temperature adjustment, fresh air system operation, etc. In more than 95% of the scenarios, human control behavior is no longer required, and it becomes AI control;

5. The intelligent irrigation system integrated with the intelligent control distribution box is installed in the flower beds and green spaces of the building to ensure the plant growth environment in the soil, maximize water use, realize water saving, energy saving, and greatly reduce the labor intensity of environmental protection.

The practical application of a 5-star hotel shows that this solution can help the hotel to achieve an ultra-high energy efficiency ratio of over 5.0.
