二、The overall artificial intelligence (AIOT) power distribution system is economical and excellent, and it is a powerful tool for low-carbon development
With the new construction scenarios of smart hotels, smart buildings, smart factories, smart parks, and smart towns, we can easily understand the overall smart power distribution system, which is the best technical solution for smart buildings in the era of AI and IoT, and it is also super efficient. Key technologies for smart buildings.
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 Specifically, the "strong and weak electricity" of traditional buildings, isolated fire control, outdated integrated wiring communication systems, and strong electricity relying on cable laying methods, etc., do not meet the requirements of smart buildings in the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.

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.
