The lost cultural relics in Yuanmingyuan were stolen in France, and the museum did not install infrared monitoring.

According to foreign media reports, 15 precious exhibits of the Fontainebleau Museum in the south of Paris were stolen on March 1st, including the Yuanmingyuan essays, copper quilts and unicorns. The French Ministry of Culture, the police anti-physical smuggling department and the Castle Management Committee have begun investigations into the case. At the same time, the China Pavilion will be closed for several months.

According to the website of Radio France International, the thieves sneaked into the pavilion at 6 am on March 1 and fled after less than 7 minutes. At present, a total of 15 exhibits have been stolen. The lost copper tire  belongs to the Yuanmingyuan essay, and is also the core cultural relic in the Fontainebleau Chinese Pavilion. A spokesman for Fontainebleau Palace pointed out that the value of stolen goods has not yet been estimated. These artworks are "priceless treasures" and the treasures of the Chinese pavilions.

■ Why is the priceless treasure easily stolen?

Liu Yang, a member of the Academic Committee of the Yuanmingyuan Academy, pointed out that the copper quilt is located in the center of the China Pavilion. In his impression, the Fontainebleau Museum is an old castle with only a low wall around it. Modern museums have a variety of high-tech anti-theft facilities. And because of the remoteness, there are fewer visitors per day, and he only saw a guarded staff at the scene. Liu Yang said that the Fontainebleau Museum has been in this state for more than 100 years. The French probably never thought that there were thieves who remembered the artifacts there.

According to the French Ministry of Culture, the theft occurred in one of the most guarded areas in the Fontainebleau Palace, equipped with an alarm system and surveillance cameras, but unfortunately for the security of the entire museum, these facilities are too It’s too simple.

■ Secretly stolen unicorn

The stolen Yuanmingyuan copper tires and silk unicorns were originally a pair. They were looted by the British and French forces in 1860. One stayed in the UK and one entered France. After the Queen of the Napoleon III, Eugenie, received the treacherous treasures from the Yuanmingyuan, he moved all the items to the bottom of the side hall of Fontainebleau Castle in 1863, including the unicorn. The other copper quilt in the United Kingdom was sold at Christie's in London in 1965 and transferred to an antique shop in London in 1989. It is now in the hands of a Taiwanese collector.

Liu Yang introduced that this piece of copper tire unicorn is 53 cm high, and the whole body is filled with sea blue scorpion for the ground. The bismuth copper wire is scaled and decorated with sapphire blue. The back cover should be used as a fuel burning appliance. After the fragrance, the aroma can spread out from the round hole in the mouth, which has both the function of viewing and practicality.

■ Where is the museum security road?

The museum brings together the civilization symbol and historical accumulation of a country, city and region. It is an important part of the cultural undertaking. The development of the museum has received the attention and support of the whole society. State-owned museums have been freely opened to the public, which has produced great social and educational significance, and has played a more important role in museum learning, education and scientific research, and has better served the public. At the same time, the safety of museums is also more important.

In recent years, the domestic government has increased investment in museum security facilities, such as the installation of more than 1,000 probes in the Palace Museum, as well as the most advanced security equipment such as infrared and explosion-proof glass. In addition, the Forbidden City is equipped with a number of security departments such as the Armed Police, the Interpol, and the Security Department. But because the Forbidden City is an old-fashioned wooden building, it is easy to cause fires, etc.

Some historical artifacts (especially textiles) in the museum are sensitive to light radiation pollution, especially ultraviolet and infrared light. Since the damaging effect of light radiation on the fiber is a gradual process, the illumination stops, and the later damage continues, and if it is in a humid environment, the deterioration process is accelerated. Therefore, in these occasions, special attention should be paid to creating a light environment suitable for the preservation of the collection.

In this case, is security a random talk? Li Yangyang, product manager of Wuhan Gaode Infrared Co., Ltd., introduced the infrared monitoring system as a new solution for the security field. Based on the most advanced infrared imaging technology, many advanced security technologies are integrated into the infrared camera. Obtaining traditional surveillance video in a completely dull environment and obtaining a clear infrared image without generating an active light source is beyond the reach of traditional surveillance equipment.

Deng Bingquan, president of the Guangdong Provincial Cultural Relics Society, believes that advanced security warnings also have sensitivity problems. People with large traffic volumes are prone to false positives, so there is a certain conflict between "technical defense" and "human defense." The product manager of Gaode Infrared believes that in places with large traffic, equipment monitoring does have certain difficulties, but the infrared monitoring system can also implement hotspot tracking, motion detection, and cross-border alarms. It also helps to solve these problems.
