Description

Technical Field

[0001] This invention belongs to the field of Internet of Things and intelligent control technology, and in particular relates to an intelligent control device for exhibit environment based on Internet of Things. Background Technology

[0002] Exhibitions and displays serve as crucial vehicles for cultural dissemination and information exchange, and the environmental quality of these events directly impacts the lifespan of exhibits and the visitor experience. With the development of IoT technology, traditional manual control and lagging environmental data management models have gradually been replaced by intelligent control systems. However, existing technologies still present many unresolved issues: 1. Limited Environmental Parameter Monitoring: Existing technologies (such as the distributed exhibition hall environmental monitoring solution in patent number 202110753198.0) only focus on temperature, humidity, and carbon dioxide levels, neglecting crucial factors for exhibit preservation, such as ultraviolet radiation intensity, PM2.5 concentration, and the content of harmful gases like formaldehyde. Long-term exposure to ultraviolet radiation can cause photosensitive exhibits (such as ancient paintings and silks) to fade and age, while PM2.5 and formaldehyde can corrode metal exhibits, contaminate paper exhibits, and negatively impact the health and comfort of visitors.

[0003] 2. Lack of personalized control considering the differences in exhibit materials: Exhibits made of different materials have significantly different tolerances to the environment. For example, light-sensitive and perishable materials such as silk and Xuan paper require strict control of light intensity and ultraviolet radiation, while metal exhibits require key humidity control to prevent oxidation and corrosion. Existing technologies (such as the intelligent analysis and control system for exhibition environments in CN118819059A) only adjust lighting based on the uniformity of light, without developing differentiated control strategies based on the characteristics of the exhibit materials, resulting in some exhibits made of special materials still facing the risk of damage.

[0004] 3. Lack of energy consumption optimization design: Environmental control in the exhibition hall (such as air conditioning operation and lighting) is the main energy consumption link. Existing technology does not take into account the peak-valley difference of real-time electricity price and the priority of environmental control needs for dynamic energy consumption optimization, resulting in serious energy waste and increased exhibition operation costs.

[0005] 4. Reliance on network transmission and lack of emergency network outage mechanism: The data analysis and command issuance of the existing system rely entirely on network connection. If a network interruption occurs, the control function will be completely ineffective, making it impossible to maintain the basic stability of the exhibition hall environment, which may lead to damage to exhibits due to sudden environmental changes.

[0006] 5. Insufficient emergency response capability: Existing technology only addresses issues such as unsatisfactory environmental comfort or lighting, and lacks a rapid response mechanism for emergencies such as exhibit displacement, tilting, or excessive levels of harmful gases, making it impossible to prevent exhibit theft, damage, or health risks to personnel in a timely manner.

[0007] 6. Limited management interaction: Existing systems are mostly local management modes, lacking multi-terminal remote access and linkage functions. Managers cannot monitor the status of the exhibition hall in real time, issue control commands remotely, or link with the security system to achieve collaborative handling of abnormal situations. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent control device for exhibit environment based on the Internet of Things, which aims to solve the technical problems of existing technologies such as single environmental parameter monitoring dimensions, lack of personalized control considering the differences in exhibit materials, lack of energy consumption optimization design, reliance on network transmission, lack of network outage emergency mechanism, insufficient emergency response capability, and single management interaction method.

[0009] To achieve the above objectives, the present invention provides an IoT-based intelligent control device for exhibition environments, comprising a multi-dimensional sensing unit, an exhibition status monitoring unit, an intelligent control execution unit, an IoT gateway, a cloud platform interaction unit, and a local storage module.

The local storage module engages in bidirectional data interaction with the IoT gateway. The multi-dimensional sensing unit collects exhibition hall environmental parameters, the exhibition status monitoring unit identifies exhibition materials and monitors exhibition posture, the cloud platform interaction unit generates control commands based on environmental parameters, exhibition material characteristics, and exhibition hall visitor flow, the intelligent control execution unit responds to the commands to achieve precise control of environmental parameters and the lighting system, and the local storage module caches key data and supports emergency control during network outages.

[0010] As an optional solution of the present invention, the detection parameters of the multi-dimensional sensing unit include temperature, relative humidity, carbon dioxide concentration, ultraviolet intensity, PM2.5 particulate matter concentration and formaldehyde content. Each parameter is collected synchronously through distributed sensing nodes, and the collection frequency can be remotely configured through the cloud platform interaction unit.

[0011] As an optional solution of the present invention, the exhibit status monitoring unit includes a material identification module and an attitude monitoring module; the material identification module collects the surface features of the exhibit through a high-definition camera and matches them with the material database (containing material parameters of more than 10 categories of exhibits such as oil painting, metal, textiles, and paper) in the local storage module to achieve material classification; the attitude monitoring module integrates a three-axis gyroscope and a tilt sensor to detect the tilt angle and three-dimensional displacement of the exhibit in real time.

[0012] As an optional embodiment of the present invention, the intelligent control execution unit includes an environmental control module and a spectral control module; the environmental control module includes a variable frequency air conditioning component, an intelligent ventilation valve, an ultraviolet shielding curtain, and a harmful gas purification module, which respectively correspond to the functions of temperature and humidity control, air replacement, ultraviolet blocking, and formaldehyde / particulate matter removal.

[0013] As an optional solution of the present invention, the spectral adjustment module has a built-in exhibit material-spectral matching database. Based on the material identification result, it calls the corresponding spectral parameters to adjust the color temperature, peak wavelength of the light, and light intensity. Among them, the ultraviolet light intensity is limited to ≤5μW / cm² for photosensitive exhibits.

[0014] As an optional solution of the present invention, the cloud platform interaction unit supports remote access from multiple terminals, has functions such as environmental data visualization, one-click distribution of control parameters, and push notification of exhibit status, and can be linked with the exhibition hall security system to realize synchronous triggering of security commands in abnormal states.

[0015] As an optional solution of the present invention, it also includes an energy consumption optimization module. This module, based on real-time electricity price, environmental regulation demand coefficient and execution unit power parameters, dynamically adjusts the regulation frequency and output power to minimize energy consumption per unit regulation effect, with an energy consumption optimization accuracy of ≤5%.

[0016] As an optional solution of the present invention, the calculation method of the environmental control demand coefficient is: λ=α×(e-2)^γ+β×(δ / δ0)+γ×η, where α, β, and γ are the weighting factors of environmental comfort, traffic flow, and exhibit material sensitivity coefficient (α+β+γ=1), respectively, η is exhibit material sensitivity coefficient, γ is environmental comfort, δ is real-time traffic flow, δ0 is optimal reference traffic flow, and e is a natural constant.

[0017] As an optional embodiment of the present invention, the conditions for the exhibit status monitoring unit to trigger an emergency response are: the exhibit tilt angle ≥ 3° or the three-dimensional displacement ≥ 5mm, or the multi-dimensional sensing unit detects a formaldehyde concentration ≥ 0.1mg / m³. 3 Smoke concentration ≥0.3mg / m³ 3 At this point, the cloud platform interaction unit immediately sends an audible and visual alarm signal, the intelligent control execution unit cuts off unnecessary power to the corresponding area, and pushes an emergency log to the management personnel terminal.

[0018] As an optional solution of the present invention, the local storage module adopts a dual backup storage architecture, caching nearly 90 days of environmental data, control logs, exhibit material parameters and emergency records. When the IoT gateway detects a network interruption, it automatically switches to local control mode, maintains basic control functions based on cached data, and automatically synchronizes data to the cloud platform after the network is restored.

[0019] The above-mentioned technical solutions in the IoT-based intelligent control device for exhibit environment provided in this embodiment of the invention have at least one of the following technical effects: 1. More comprehensive monitoring dimensions to ensure the safety of exhibits and personnel: For the first time, key parameters such as ultraviolet intensity, PM2.5, and formaldehyde are included in the monitoring scope, covering the core needs of exhibit preservation and personnel health. This solves the problems of exhibit damage and personnel discomfort caused by the single monitoring of existing technologies, and increases the environmental parameter compliance rate to over 98%. 2. Achieve personalized control of exhibits and provide targeted protection for exhibits made of special materials: By accurately matching the material of exhibits through the material identification module and combining the material-environment / spectral matching database, differentiated control strategies are formulated for exhibits made of different materials (such as strictly controlling ultraviolet radiation for photosensitive materials and strictly controlling humidity for metal materials). This avoids the risk of damage to exhibits made of special materials caused by the "one-size-fits-all" control of existing technologies and extends the lifespan of exhibits by more than 30%. 3. Energy-efficient design to reduce operating costs: By introducing an energy-efficient design module and combining real-time electricity prices with dynamic adjustment strategies based on control needs, the energy consumption for exhibition hall environmental control can be reduced by 15% to 20% while ensuring the safety of exhibits and the visitor experience, thus significantly reducing electricity expenses for exhibition operations. 4. Network outage emergency mechanism to improve system stability: Adopting local storage dual backup and automatic switching mode when the network is out of service, it solves the problem of control failure caused by the reliance on the network in the existing technology. It can still maintain basic control functions in the absence of network, ensure the stability of environmental parameters, and avoid damage to exhibits due to sudden environmental changes. 5. Timely emergency response and strong risk prevention capabilities: In response to emergencies such as abnormal exhibit posture or excessive levels of harmful gases, a multi-layered emergency response mechanism of "audio-visual alarm + terminal push + equipment linkage" is established, with a response time of ≤3s. This can quickly prevent theft or damage of exhibits or risks to personnel health and improve the level of exhibition hall security management. 6. Multi-terminal linkage and data visualization improve management efficiency: Supports remote management via Web and APP, allowing managers to monitor the exhibition hall status and issue control instructions in real time without on-site duty. The data visualization function facilitates the tracing of historical data and analysis of control effects. At the same time, it links with the security system to achieve integrated management, improving management efficiency by more than 50%. Attached Figure Description

[0034] II.

[0035] (II) Deployment of Exhibit Status Monitoring Unit Each of the 50 exhibits is equipped with one monitoring unit. For exhibits in open display (ceramics and metal artifacts), the monitoring units are deployed on both sides of the display shelf (0.5m away from the exhibits), while for exhibits in display cases (ancient paintings, silk, and paper documents), the monitoring units are deployed on the top inside the display case. The high-definition camera for the material recognition module has a resolution of 2592×1944, a frame rate of 30fps, a shooting angle of 90°, a distance of 1.5m from the exhibit, and a material matching threshold of 85%. The attitude monitoring module has a three-axis gyroscope sampling rate of 100Hz, a tilt sensor threshold of 3°, and a three-dimensional displacement threshold of 5mm.

[0036] (III) Deployment of Intelligent Control and Execution Units Environmental control module: Inverter air conditioner: deployed at 200㎡ / unit, a total of 5 units, power 3kW, temperature adjustment range 16℃~26℃, accuracy ±0.5℃; Intelligent ventilation valves: linked with the exhibition hall's fresh air system, one valve is configured in each sub-area, for a total of 100 valves, with an opening adjustment range of 0%~100%; UV shielding curtains: installed inside the exhibition hall windows, 20 in total, driven by a 50W motor with a lifting speed of 0.1m / s; Harmful gas purification module: 20 units per 50㎡, power 80W, formaldehyde purification efficiency 92%, PM2.5 purification efficiency 95%.

[0037] Spectral adjustment module: Each exhibit is equipped with two LED adjustable spectrum spotlights, totaling 100, with a power of 20W, a color temperature of 2700K~6500K, a peak wavelength of 450nm~650nm, and a light intensity of 0~500lx; The ultraviolet intensity limit for ancient paintings and silk exhibits is ≤5μW / cm², for paper documents ≤10μW / cm², and for metals and ceramics ≤20μW / cm².

[0038] (iv) IoT gateway and cloud platform configuration IoT Gateway: Deployed in the central control room of the exhibition hall, it adopts LoRa / WiFi dual-mode, connects 100 sensor nodes, 50 sets of exhibit status monitoring units, and 100 intelligent control and execution units, with MQTT communication protocol and AES-128 data encryption method; Cloud platform: Based on Alibaba Cloud ECS server, configured with 4 cores, 8GB memory, and 100GB cloud disk, supporting 50 terminals online simultaneously, data storage period of 1 year, and early warning push latency ≤1s.

[0039] (v) Configuration of energy consumption optimization module and local storage module Energy consumption optimization module: Real-time electricity price is obtained through the State Grid API, and peak, valley and normal periods are set according to local standards. Weighting factors α=0.4, β=0.3, γ=0.3. Sensitivity coefficient of exhibit material: ancient paintings and silk η=1.0, paper documents η=0.9, metals η=0.3, ceramics η=0.3; Local storage module: 64GB SD card, 1TB solid-state drive, adjusts based on the past 7 days of historical data in network outage emergency mode, and synchronizes data within 1 minute after network recovery.

[0040] III. System Workflow (a) Data collection phase The multi-dimensional sensing unit collects temperature, humidity, carbon dioxide, ultraviolet intensity, PM2.5, and formaldehyde data for each sub-area every 10 minutes. After preprocessing, the data is uploaded to the cloud platform via an IoT gateway. The exhibit status monitoring unit collects exhibit images and posture data in real time. The material recognition module matches materials every 30 minutes, and the posture monitoring module collects three-dimensional coordinates and tilt angle data every second, uploading the data in real time when an anomaly occurs.

[0041] (II) Data Analysis and Instruction Generation Stage After receiving the data, the cloud platform calculates the environmental comfort level γx and the environmental regulation demand coefficient λ. The energy consumption optimization module combines real-time electricity prices, λ values, and the sensitivity coefficient of exhibit materials to generate energy consumption optimization suggestions (such as reducing the intensity of the spotlights on the ancient paintings to 100 lx during peak hours and adjusting them to 150 lx during off-peak hours). The cloud platform takes into account the overall environmental comfort, exhibit material characteristics, visitor flow, and energy consumption optimization suggestions, and generates control commands (such as instructing the inverter air conditioner to run in cooling mode with a power of 2kW when the temperature is higher than 22℃; instructing the harmful gas purification module to start and the intelligent ventilation valve to open to 100% when formaldehyde exceeds the standard).

[0042] (III) Implementation Phase of Regulation After receiving the control command, the intelligent control execution unit performs the corresponding operations: the environmental control module adjusts the operating status of the air conditioner, ventilation valve, shielding curtain, and purification module; the spectrum adjustment module adjusts the color temperature, spectrum, and intensity of the spotlights, collects feedback data in real time after adjustment, and uploads it to the cloud platform to verify the control effect.

[0043] (iv) Emergency Response Phase If an exhibit is detected to be tilted at an angle of 3.5° (exceeding the standard), an audible and visual alarm will be triggered immediately, a warning message will be pushed to the management personnel's APP, and the security system will be activated to lock the corresponding area's entrance and exit. If the formaldehyde concentration is 0.12 mg / m³ (exceeding the standard), the harmful gas purification module and intelligent ventilation valve will be activated. After 15 minutes, the concentration will drop to 0.04 mg / m³ (qualified), and the system will return to normal operation. If the network is interrupted, the local storage module automatically switches to emergency mode, maintaining environmental parameters (temperature 20℃, humidity 55%, light intensity 100lx) based on the historical data of the past 7 days, and synchronizing the data during the network outage after the network is restored.

[0044] (v) Management and Traceability Stage Managers can view exhibition hall environmental data, exhibit status, and control logs in real time via an app, and remotely adjust the collection frequency and control parameters (such as adjusting the humidity of the paper document exhibition area to 58%). The cloud platform automatically stores historical data and supports queries by time and region, facilitating subsequent analysis and optimization of control strategies.

[0045] IV. Implementation Results Verification The device was tested at a museum for 30 days, and the results showed: The compliance rate of environmental parameters has increased from 85% with the original technology to 99%, with 100% compliance rates for ultraviolet radiation intensity, formaldehyde, and PM2.5. Exhibits made of special materials (ancient paintings, silk) showed no signs of fading or aging, and metal exhibits showed no signs of oxidation or rust. Energy consumption for exhibition hall environmental control has been reduced by 18% compared to the original technology; During the network outage test (simulating a 2-hour network interruption), the environmental parameters fluctuated by ≤±3%, which did not affect the safety of the exhibits. The emergency response time is ≤3 seconds, and managers can receive early warnings in real time and handle them remotely. No damage to exhibits or safety accidents have occurred.
