Project Overview Yan’an Museum is located in the landscape area of Yan’an New District, adjacent to Yan’an Grand Theater, with a total land area of 124.04 acres (about 82,693 square meters) and a total area of 63,358 square meters (exhibition area of 16,210 square meters). The building consists of four floors, with equipment and storage areas under the ground and three floors of exhibition areas above the ground, which are functionally divided through corridors and arched bridges to comprehensively display the natural history and folk culture of Yan’an. Requirements for the creation of an intelligent museum Precise environmental control of cultural relics protection requires strict control of temperature, humidity, light and air quality (e.g., paper cultural relics require constant temperature and humidity to prevent mold growth, and light is not enough to prevent fading of artwork), and traditional manual control is difficult to meet the requirements in real time. Safe and reliable prevention of theft and loss of valuable artifacts relies on a high level of security measures (video surveillance, access control connectivity), and the system must be able to handle emergencies such as fires and safeguard equipment for emergency use. Energy efficiency and low carbon management of large venues. Energy consumption of electrical and mechanical equipment accounts for more than 60% of operating costs and requires data-driven strategies to reduce inefficient energy consumption (e.g., over-cooling of air-conditioning systems, gas consumption for lighting). Smart experiences that optimize visitor comfort (self-learning temperature and humidity control), service efficiency (crowd analysis and visit optimization), and responsiveness of operations and maintenance (fault alerts) have a direct impact on a facility’s reputation. Confus IoT Smart Solutions 1 – Building Automation Systems (BAS) – “Smart Hubs” for environments and devices. Dynamic environmental control: Setting up multi-mode sensors (temperature, humidity, light and CO2 concentration), connecting air conditioning and fresh air systems, and realizing precise control of environmental parameters ±0.5℃ in the exhibition area. Energy Efficiency Optimization Algorithm: Based on the prediction of visitor density, outdoor temperature and humidity, it automatically adjusts the operation mode of the equipment (e.g., switching to energy-saving mode at night), which reduces the energy consumption of the air-conditioning system by 22%. 2 . Integrated platform for IBMS facility management system Cross-system collaboration: Integration of 12 subsystems such as security, lighting, elevator, etc. for “single emergency response” (e.g., automatic power shutdown and activation of smoke evacuation system in case of fire). Data-Driven Decision Support Data-drivendecision support : Create equipment safety models to prevent potential failures (e.g., corroded elevator bearings), thereby extending maintenance response time by 32 times. 3 – Energy consumption monitoring and lighting control system – energy-saving dual motors Partial meter analysis: statistics of energy consumption data for each sub-scope, identification of high energy consumption connections (e.g. 23% for air conditioning in a scope), provision of inverter recommendations, replacement of lighting with LEDs, payback period ≤ 2 years. Adaptive Lighting: Connect light sensor + human body sensor to realize “turn on the light near and turn off the light far away”, lighting energy consumption 35%. 4-Adaptive scene Exhibition protection: UV-free lighting and low-oxygen environmental controls were used in the artifact storage area to slow down material deterioration. Diversion strategy: Combining a reservation system, air-conditioning pre-cooling system in the exhibition area, and corridor lighting conditioning system to guide the flow of people, the visitor experience has been improved by 40%. Application Value and Efficiency Improvedprotection of cultural heritage: 99.5% compliance with environmental regulations and a 30% reduction in the risks associated with the protection of cultural heritage. Dramatic increase in energy efficiency: 28% reduction in equipment energy consumption and 920 tons of CO2 emissions per year. Optimized operation and maintenance costs: the digital chemical ordering system reduced downtime for repairs from 8 hours to 45 minutes, saving 50% in labor costs. Increased social value: the average annual number of visitors increased by 18%, making it a major vehicle for cultural and international exchange in Yan’an. Conclusion: reinventing cultural spaces with technology Through the four core solutions of CtrlWorks BAS IoT Mirror ,IBMS Integration Platform ,Energy Consumption Monitoring Systemand IntelligentLightingControl, an intelligent neural network of “sensing, analyzing, and decision-making” has been created for the Yan’an Museum to promote its transformation from a traditional exhibition space to a “smart city living room with a low carbon footprint”.
