Is the collection of cultural relics growing? Museum Environmental Monitoring System: It's my turn to play
The collection of cultural relics in the museum has hairy in the display cabinet? What's happening here! On June 12, a Weibo that 'I saw these two cultural relics grow hair in Qianling Museum' aroused public attention. According to the person in charge of the Qianling Museum, the cultural relic experienced salt precipitation due to weather and temperature changes, which is what netizens said the cultural relic has hairy. At present, the cultural relics have been withdrawn into the restoration room, waiting for a thorough inspection by relevant cultural relics scientists. The cultural relics in the museum carry the Chinese civilization for thousands of years. As the carrier of ancient Chinese culture, these cultural relics have witnessed the long history of our country. As an important place for the display, storage and storage of cultural relics, museums must take effective measures to protect cultural relics and better display and maintain the cultural, historical and artistic value of cultural relics. Next, this article will analyze and explore museum environmental management through the museum environmental monitoring system, hoping to guide the environmental monitoring of museums in my country. Museum environment monitoring system The museum environment monitoring system is a system for real-time monitoring of museum environment conditions. The system can monitor the museum environment, largely avoiding temperature, humidity, noise, gas, etc. Environmental factors have harmful effects on collections. The museum environmental monitoring system adopts wireless sensor network technology to realize the collection of environmental data within the monitoring range of the museum. Monitoring and transmission of data, real-time, monitoring and management of cultural relics storage environment to ensure the safety of cultural relics storage environment. The composition of the museum's environmental monitoring system 1. Indoor temperature and humidity monitoringAmong various environmental factors, the environmental factors affecting museum cultural relics are mainly air temperature and humidity. The impact of temperature on the storage of cultural relics is mainly reflected in the thermal expansion and contraction when the temperature difference is large. When temperature and humidity, light, oxygen, insects, mold and other environmental factors act, it will accelerate the damage to cultural relics. Within a certain temperature value, every time the temperature rises by 10°C, the reaction speed will immediately increase by 1-3 times. Similarly, when the humidity is too high or too low, it will cause serious damage to organic cultural relics. Therefore, the installation of temperature and humidity sensors to regulate temperature and humidity is very important for the protection of cultural relics. II. Indoor air quality monitoring In order to reduce the undesirable factors that affect the preservation of cultural relics, and to create a good viewing environment for the audience, the relevant departments of China have formulated various factors in the exhibition hall environment. Standard values u200bu200band hygiene requirements (GB/T 18883-2002)The indoor air monitoring system mainly relies on air quality sensors, which can detect temperature, humidity, pressure, light, PM2.5, PM10, TVOC, etc. in the air Numerical values, as well as oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (CH2O) and other gas concentrations, are integrated with multiple elements and have very powerful functions, basically covering various indicators reflecting air quality. Real-time monitoring of the indoor air quality of the museum, when one of the monitoring factors exceeds the limit value, immediately alarm and notify the management staff. 3. Water leakage monitoring When the window/air conditioner leaks, it will have a certain impact on the museum environment. Therefore, it is necessary to install a water flood sensor at the opposite position of the museum to monitor the water leakage in real time. In the event of a water leak, the police shall immediately report to the police and notify the relevant personnel to take measures. Four. Anti-theft alarm system Install human infrared detectors at the entrances and exits of museums, such as doors, windows, and corridors, to collect data from the on-site human infrared detector alarm signals. In case of situation, a sound and light alarm will be issued, and the administrator will be notified by telephone. 5. Automatic fire alarm systemThe smoke sensor, temperature and humidity sensor, sound and light sensor in the museum environment monitoring system constitute the fire alarm system. When an alarm occurs, it will trigger the smoke sensor to emit sound and light alarms, and report the type of alarm through voice. 6. Intelligent access control management The museum is equipped with electronically controlled door locks. When staff enter important places, they must first swipe their card and then enter the password. After verification by the access control host, they can enter. The system automatically records the staff information at the same time, so as to avoid loss, and can be traced back. Seven. Video surveillance systemThe video surveillance system adopts mature digital hard disk video recording technology. Infrared cameras are installed in the warehouse to realize 24-hour uninterrupted image monitoring of the warehouse, and can playback and query video records. 8. Centralized data monitoring and alarm To achieve cross-regional centralized monitoring and management of multiple exhibition halls distributed on each floor, and realize the monitoring of the environmental data of each floor exhibition hall through the tree list method. Show data in the form of charts or maps. Nine. Data Statistics Reports The monitoring system provides daily/monthly/yearly statistics and customized report statistics for the monitoring volume of each site. You can choose the start and end time, and select a specific monitoring volume for daily Statistics, and support the data table export function. The museum environment monitoring system has the functions of data collection, data statistics, over-limit alarm, and remote monitoring. Through remote monitoring, the cultural relics warehouse is used to ensure the proper and safe cultural relics. According to the actual situation, corresponding measures can be formulated to promote the development of the museum's cultural relics protection.
