Cultural relics and ancient buildings are treasures of the Chinese nation's historical and cultural heritage, carrying rich historical information, artistic value, and scientific significance. However, due to their long construction history, flammable building materials, and severe aging of electrical systems, cultural relics and ancient buildings face severe challenges in terms of electrical safety.

　　R&D Background

Poor fire resistance and extremely high risk of fire

Mainly wooden structure (such as beam column, arch of wooden architecture and roof), supplemented by combustible decorative materials, with extremely low fire resistance rating (mostly Grade 4 or no specific fire resistance rating), poor fire resistance and high risk of electrical failure.

The line is aging and there is a serious problem of unauthorized connections

Early construction of ancient electrical circuits often used non flame retardant cables, with severely aged insulation layers that were prone to leakage and short circuits; Newly added equipment (such as lighting and monitoring) in the later stage often have temporary wiring, which is not included in the formal power distribution design.

Significant changes in electrical load

Local areas (such as cultural relics exhibition areas and restoration rooms) are concentrated due to the concentration of precision equipment; Other areas (such as courtyards and ancillary buildings) have scattered loads, which can easily lead to fluctuations in end use electricity caused by "small loads and long lines".

On July 8, 2024, a fire broke out at the Huang Gongwang Memorial Hall in Fuyang District, Hangzhou due to a short circuit in the electrical circuit.

solution

Li'an Technology relies on Dianyi Cloud to develop solutions tailored to the electrical characteristics of cultural relics and ancient buildings. These solutions aim to improve the power supply safety and electrical safety of cultural relics and ancient buildings, in order to achieve intrinsic safety in their electrical usage.

　　

Solution: Li'an Technology relies on Dianyi Cloud to develop solutions tailored to the electrical characteristics of cultural relics and ancient buildings. These solutions aim to improve the power supply safety and electrical safety of cultural relics and ancient buildings, in order to achieve intrinsic safety in their electrical usage.

Install smart power detectors at the distribution box or regional distribution box in the middle of cultural relics and ancient buildings to monitor real-time parameters such as current, voltage, and power of the power supply system, as well as the temperature of the incoming and outgoing circuit nodes. If any hidden dangers are found, they will be promptly reported and dealt with to ensure the safety of the power supply system.

Dianyi Cloud aims to improve power operation safety and reduce operation and maintenance costs. Through IoT collection terminals, real-time electrical operation data such as current, voltage, harmonics, as well as environmental data such as contact point temperature, environmental temperature, and humidity, are uploaded to the cloud to build a safety monitoring model for system operation. The operation of the power supply system is monitored in real time, and any hidden dangers are immediately alerted through phone, WeChat, and SMS, reminding management personnel to handle them in a timely manner, effectively ensuring the safe and controllable operation of the power supply system and power consumption system.

Security guarantee and efficiency improvement

Electricity safety guarantee: Comprehensive monitoring and protection of the power supply system to effectively prevent electrical fires. Realize the intrinsic safety of electrical use in cultural relics and ancient buildings, and prevent electric shock accidents. Improve power quality and ensure equipment safety.

Management efficiency improvement: Provide intelligent management systems to enhance management efficiency. Enhance the scientific and standardized management of electricity for cultural relics and ancient buildings. Provide advanced demonstration for the management of cultural relics and ancient buildings, and enhance the overall management level.

　　

This plan can not only effectively reduce the risk of electrical fires and ensure the safety of cultural relics and ancient buildings, but also improve the efficiency of electricity management and reduce operating costs. In the implementation process, the special characteristics and protection requirements of cultural relics and ancient buildings should be fully considered to ensure the scientificity and feasibility of the plan. The implementation of this plan will provide strong technical support for the protection and inheritance of cultural relics and ancient buildings.
