There will be no dead ends in the monitoring of the Forbidden City next year

Anti-paper window change to glass, difficult to bear the burden of the need for gradual replacement of the experiment For the Palace Museum, is the replacement of all the glass or remain the same, in the industry experts have some arguments.

Some experts believe that the Forbidden City is a unit of world cultural heritage. The most important thing is to maintain the authenticity, integrity, and historic features of history. If all glass is replaced, it will no longer be the original National Palace Museum. Even the information in the Forbidden City about bricks, tiles and stones is historical information, and it cannot be evasive.

On the other hand, since the windows of the Forbidden City were initially covered with paper paste, bearing weight problems were not involved. Now if you need to replace materials that are necessary for situations such as flood prevention, UV protection, explosion-proof, and good light transmission, it will inevitably affect The load bearing on the window frame caused the vulnerable condition of the window frame, and even the problem that the glass was not broken and the window frame was damaged. For security reasons, the Forbidden City still chooses to gradually replace the glass.

Taking the replacement of new types of glass with the present Chenggonggong and Yonghegong as examples, they have been repeatedly tested after only a long period of testing. Therefore, the new glass of the Qiankun Palace is an experimental process. Under the premise of conducting data detection in various aspects and ensuring that the window frames can withstand, it will be replaced one by one.

Due to the special identity of the Forbidden City, glass replacement must be submitted to the cultural relics management department for approval, and the relevant department should conduct a second argument to enable the actual replacement.

However, at the same time, the incident in which the glass of the Qiankun Palace was broken by bare hands will also prompt the National Palace Museum to speed up the progress of glass updating and upgrading work.

"According to the results of the current test, if it is successful, the area around the West 6th Palace should be replaced in about a year. However, the specific time will depend on the detection situation," said Zhu Hongwen.

The technical protection and security transformation has been completed 75%, next year monitoring "no dead ends"

In view of the fact that the camera in the courtyard did not directly capture the instant scene in which the perpetrators shattered the glass, and failed to provide a more intuitive basis for the investigation of the facts, the Palace Museum will intensively install high-definition cameras throughout the Forbidden City and send video surveillance at the same time. The management personnel ensure that there is no full coverage of “dead ends” within the 100-hectare area of ​​the Palace Museum.

At present, the National Palace Security Renovation Project has completed 75% of the total number of contracts, most of which have been put into use and are expected to be completed before the end of this year.
