Recently, the President of the Palace Museum proposed that on the occasion of the 600th anniversary of the establishment of the Forbidden City, the Palace Museum will successively launch many fine cultural relics, including the famous ancient paintings, the Qingming Shanghe map. The reappearance of cultural relics can make people feel the profoundness of traditional culture, but at the time of the exhibition, the protection of cultural relics should pay special attention.

In general, cultural relics have great conditions when they are on display, and they are required for ambient temperature, moderateness, carbon dioxide, and microorganisms. In the past, manual testing was generally required, but with the continuous development of technology and market demand,sensors have become a commonly used monitoring instrument in cultural relics protection.

Through the sensors deployed in the showcase, you can sense the light intensity, UV intensity, carbon dioxide concentration, ambient temperature and humidity, and even the concentration of volatile organic compounds in the area. Once an emergency occurs, the staff can quickly find out the abnormality. Specific location, take appropriate remedial measures in a short time.

For example, the collection environment quality monitoring system currently used by the Hubei Provincial Museum can implement all-weather monitoring of the collection of cultural relics. By using more than 100 different types of sensors, the temperature, humidity, illuminance, ultraviolet light, etc. of the storage environment can be detected.
In addition to the collection of artifacts, more and more outdoor artifacts have now used sensors to ensure the safety of cultural relics. For example, more than 150 sensors such as displacement sensors, strain sensors, pressure sensors, temperature sensors, and wind speed sensors are installed on the Liuhe Tower in Hangzhou, Zhejiang Province, which can fully grasp the development process of various structural diseases;

Guangzhou Nanyue National Wooden Sluice Gate Site is installed. 64 sensors, monitoring content including hydrology, environment, temperature and humidity, etc., can analyze the root cause of the disease at the sluice site; pass the air temperature sensor, air humidity sensor, soil temperature sensor, soil moisture content sensor, wind direction sensor, wind speed in West Lake The use of sensors such as sensors has established an automated monitoring system.

The use of sensors can also better protect cultural relics. In some warehouses where the treasures of Wenbo history are treasured, sculptures and bronzes are generally equipped with pressure sensors; the hanging paintings are equipped with tension and displacement sensors. In addition, for the walls of the warehouse, vibration sensors can be used to prevent thieves from stealing through digging.
The use of these sensors protects the safety of cultural relics, while the protection of cultural relics is also driving the advancement of sensor technology. From structural sensors that use structural parameter changes to sense and transform signals, to solid-state sensors composed of solid components such as semiconductors, dielectrics, and magnetic materials, to smart sensors combined with microcomputer technology and detection technology, sensor technology. It is also constantly moving forward.

According to statistics, at present, there are more than 4,000 museums in China and more than 30 million pieces of cultural relics. With the constant attention of people's awareness of preventive protection of cultural relics, the protection of these cultural relics will require the use of a large number of sensors for sensors. The industry will also usher in a new round of important opportunities and challenges.

However, it should be noted that at present, there are still many problems in the development of China's sensor industry, such as weak innovation capability, breakthrough of key technologies, unreasonable industrial structure, and weak corporate capabilities. For related companies, we must seize development opportunities, break through the imprisonment of technology, and achieve rapid development of enterprises.
