Monitoramento ambiental de museu facilitado com a tecnologia LoRa

Os museus são o epítome da história e da cultura, onde podemos sentir as mudanças históricas e culturais de um país e de uma cidade. O conceito de proteção preventiva de relíquias culturais tornou-se o consenso da proteção internacional do patrimônio cultural. No aspecto da proteção das relíquias culturais museológicas, é muito importante aproveitar a tecnologia da Internet das Coisas para implementar monitoramento e gerenciamento eficazes de seu ambiente de preservação, que pode prevenir ou reduzir ao máximo os danos causados ​​por fatores ambientais às relíquias culturais. Aqui, discutiremos as implementações de LoRa no monitoramento ambiental de museus.

Por que usar a tecnologia LoRa para monitoramento ambiental de museus

Museums are often large and complex historic buildings where rearranging networks and circuits is rather difficult. Mesmo que seja possível, a tarefa de reconstrução é cara e os dispositivos de detecção geralmente precisam ser fixados em uma determinada posição. Wireless sensors seem to be a great option, mas devido ao uso pesado de concreto e aço, esses edifícios históricos fornecem um ambiente difícil para tecnologias sem fio. As soluções baseadas em WiFi não são fáceis de instalar, caro, e limitado em cobrir grandes áreas e manter conectividade consistente.

Em comparação, LoRa tem as vantagens de longa distância, baixo custo, Baixo consumo de energia, e ampla cobertura. A conexão LoRa não requer cabos extensos ou infraestruturas adicionais, permitindo flexibilidade e simplicidade na implantação de soluções de IoT na infraestrutura existente. Ele pode combinar melhor a cobertura de rede com a sensibilidade do sensor para fornecer monitoramento em tempo real do ambiente de exibição de arte para museus ou galerias, bem como estruturas complexas localizadas ao ar livre. Portanto, Dispositivos LoRa ajudam a preservar tesouros culturais e históricos, permitindo que as gerações futuras desfrutem e aprendam com séculos de coleções de arte.

Como LoRaWAN funciona no monitoramento ambiental de museus

A solução de conservação de arte inteligente baseada em LoRa consiste em sensores baseados em LoRa, Gateways habilitados para LoRa, e um sistema de monitoramento baseado em nuvem. Nós sensores implantados em todo o museu coletam informações ambientais, como temperatura, e umidade em tempo real, e transmitir os dados para o gateway, que então enviará os dados para a nuvem onde serão processados ​​e analisados. Então, o cliente final pode monitorar e processar os dados ambientais de cada coleção em seu dispositivo terminal, como computadores e smartphones.

Implementações da tecnologia LoRa na conservação de museus

A qualidade da preservação e a longevidade das relíquias culturais dependem principalmente do ambiente de preservação em que estão localizadas. Portanto, a chave para aliviar os danos de relíquias culturais causados ​​por fatores ambientais reside no controle de vários fatores do ambiente de coleção, como temperatura, umidade, leve, poluentes do ar, etc. para que as relíquias culturais possam ser mantidas em um ambiente estável e limpo tanto quanto possível. Abaixo serão mostradas algumas implementações de LoRa em soluções de monitoramento ambiental de museus.

Monitoramento de temperatura e umidade
Como o principal fator ambiental que afeta a preservação a longo prazo de relíquias culturais, a mudança de temperatura e umidade não só acarreta o enfraquecimento da resistência física das relíquias culturais e a deformação que não pode ser restaurada, but also plays a direct or indirect synergistic role in the process of cultural relics being damaged such as corrosion and mildew. Portanto, the museum has always regarded the control of temperature and humidity as the primary condition of cultural relics environmental control.

MOKOLoRa LW002-TH sensor is an advanced temperature and humidity sensor that can be leveraged to monitor the temperature and humidity of the museum environment. Once the data exceeds the threshold, an alert will be sent to the museum administrator in a timely manner.

Monitoramento da qualidade do ar
In order to reduce the unfavorable factors affecting the protection of art collections and cultural relics and create an ideal exhibition environment for the visitors, there are certain standards of air quality for the exhibition hall environment. Indoor air monitoring relies mainly on LoRa air quality sensors, which are scattered all over the museum and can detect the concentration of some polluting gases in the air.

Light & UV monitoring
Exposure to light can cause photochemical reactions in cultural relics materials, accelerating the aging or discoloration of these materials, especially organic cultural relics such as textiles, paper, and wood, as well as light-sensitive artifacts like painting works. Museum lighting monitoring sensors can help administrators measure light and ultraviolet light levels to keep artifacts in the right lighting conditions.

Water leakage monitoring
Water leakage from windows or air conditioners will definitely have an impact on the museum’s environment. Portanto, it is necessary to install water leakage sensors at the appropriate locations in the museum to monitor where there is a water leakage. In case of water leakage, an alarm shall be given immediately and relevant personnel shall be notified to take measures.

Burglar alarm system
At the entrance and exit of the museum such as doors, janelas, corridors, etc., LoRaWAN PIR sensors are adopted to monitor and secure the museum. When the thief approaches, the infrared rays generated by himself radiate to the sensor, which will cause the temperature of the sensor to change, and the sensor will issue an alarm to the system. The sensors will not affect each other, and the installation is very convenient.

Automatic fire alarm system
The intelligent fire alarm system based on LoRa, combined with smart devices such as smoke detectors, temperature and humidity sensors and wireless gateways, has built a strong fire protection system for the museum. when an alarm situation occurs, the smoke alarm can be triggered to give out sound and light alarms, and the alarm type will be transmitted to the administrator instantly, which greatly improves the timeliness and accuracy of fire detection.

Benefits of LoRa integration in museum and art collections

The benefits of a LoRa-based museum environmental monitoring solution are numerous, from real-time monitoring of each collection to creating a better exhibition environment. LoRa-based IoT solution caters to the needs of museums and saves thousands of dollars for them.

Remote monitoring and real-time alerts
The museum environmental monitoring system can remotely monitor and manage all the environmental monitoring equipment, and view the monitoring data anytime and anywhere. These data are presented in various forms, and historical data can be viewed, downloaded and printed. além disso, you can set a certain threshold in the cloud platform. Once the monitored real-time data exceeds the upper or lower limit, the platform will send alarm information to the staff by phone or email in time.

Efficient art health monitoring
LoRa-enabled sensors take advantage of low-power consumption to provide accurate, eficiente, and simple art health metrics for conservators in real-time. These metrics help to improve the preservation environment of collections, thus reducing the risk of corrosion and extending the life of cultural collections.

Easy installation and maintenance
For museums, the installation of large-scale equipment will have an influence on the storage of cultural relics. A large number of collections need to be removed and stored in a proper temporary environment, or they will most likely to be damaged. LoRa-based museum environmental monitoring solution has little impact on the exhibition environment, and the deployment of sensors and networks will not affect cultural relics.

Redução de custo
Cost reduction is one of the primary benefits of leveraging smart art conservation solution. LoRa solutions are cost-effective and do not require the deployment of additional infrastructure. The lora-based network is much cheaper to implement and maintain than the network based on other protocols, and the low network hardware requirements and low power consumption in the LoRa environment make it a very cost-effective IoT infrastructure.

Better exhibition environment
By collecting data about the exhibition environment such as temperature, umidade, e qualidade do ar, visitors are enabled to enjoy a better museum environment. The number of visitors opening to each exhibition hall can be effectively controlled, isso é, if the data exceeds a certain value, visitors who are about to enter the museum will be warned that they should not visit.
