After the incident occurred, a spokesperson of the Palace Museum disclosed that the security system of the Palace Museum, which cost tens of millions, was being upgraded, but the central control room has not been completed and the new security system will be put into use next year.
Wei Qi, chief telecommunications engineer of China Aviation Industry Planning and Design Research Institute, told reporters that the museum's security system usually includes human protection, physical prevention, and technical prevention.
The civil air defense is based on the security department, and is composed of personnel, security personnel, and personnel from various functional departments, such as security patrols, security inspections, and security guards.
Physical defense is a defense system with the theme of buildings, and various supporting facilities, including security doors, security windows, and physical walls. The technical defense includes infrared and other high-tech technical equipment.
Talking about the high-tech security system of the Palace Museum, Hou Xiaoxun said that the first line of defense for the anti-theft alarm system is the perimeter alarm. It can help night-time duty personnel find the target and provide the basis for the earliest detection, providing valuable processing time for rounding operations.
At present, the commonly used perimeter alarm equipment in China usually has infrared radiation alarm detectors, vibration cables, microwave walls and other products.
Infrared radiation detector is a widely used peripheral alarm product. Because it is cheap, it is popular, and its main function is to prevent people from illegal traffic.
The second high-tech defense line of the Forbidden City is the channel alarm. It refers to the anti-theft alarm systems of doors, windows, walkways, and courtyards in the protection area. It mainly uses existing detectors, infrared fences and other equipment.
Indoor space alarm is the third line of defense of the anti-theft alarm system. The products include multi-source passive infrared detectors, microwave detectors, and glass break detectors.
Among them, microwave detectors have high sensitivity, and have the function of penetrating glass, wood and other non-metallic materials. They can be concealed and installed to avoid the criminals' footwork, improve the ability to resist technological theft, and can also point the microwave detectors out of the window. When the perimeter alarm is used.
The display cabinet alarm is the last line of defense for the anti-theft alarm system. At present, there are pressure sensors and displacement sensors used in the country. Hou Xiaoxun introduced that according to the relevant regulations, a museum’s security system can meet the needs as long as it has the above three types. In addition, when some foreign exhibition companies hold exhibitions at the Forbidden City, they will also request another set of security systems.
“The security system that we did at Sungoo Hall is actually the second security system of the Zhai Gong. It includes infrared alarms and standing wave alarms. We can do so as long as someone opens the display case during the day and the instrument will immediately call the police. However, construction Just three days after the completion of the case, theft occurred." Hou Xiaoxun said.
Integrated system is a good security system Wei Qi believes that a good museum security system should be an integrated system, which includes a set of effective management system, a set of stable and reliable technical protection equipment, a set of practical Emergency plans, a group of dedicated security guards, are indispensable. If a museum has installed many cameras and alarm detectors, the theft occurred, the anti-theft alarm system warned, and the cameras also saw it. However, if it were not caught, it would not be a good system.
Hou Xiaoxun said that any type of high-tech instrument is flawed and requires multiple instruments to be used together to compensate for each other's defects, so as to form an overall prevention network.
For example, one of the problems with these products is that the control system can only display an alarm in a certain location after an alarm occurs. Can it not be explained as a false alarm or a real report? Is it animal or human? Is an alarm triggered by someone from inside or outside? In order to confirm that it must be supplemented by a camera review, there is also a problem that, if it is raining, fogging, or nighttime, the camera review will not fully play its role, reflecting the fact that the actual situation of the field does not appear.
In addition, the infrared detectors also have the fly in the ointment, that is, fog infrared detectors will all fail, which requires the use of laser detectors in the fog area.
The theft of museums by ordinary criminals is well-prepared and carefully planned. The museum’s security guards are unprepared for protection, and the thefts basically happen in the evening. The on-duty staff suddenly receives the alarm and finds that theft will be in a hurry, often delaying valuable processing time.
No matter how good the high-tech products are, Hou Xiaoxun, who needs human control, believes that the security system at night is indeed a major weakness for the Imperial Palace. The National Palace Museum has a high demand for fire protection. Although there are 400 cameras, the number of infrared cameras at night cannot be too high. Due to the relatively large infrared lighting power, it is easy to cause fire, and it is also dangerous for the safety of cultural relics.
It is also the cause of fire. The National Palace Museum is a set of two different security systems during the day and night, and it is powered by two channels. In order to prevent fire, in the evening, the power supply system of the security system will be broken during the day and replaced with power supply of the security system at night, which causes many advanced security systems to completely lose their power due to loss of power.
“I personally think that the two-way power supply that the Palace Museum used for night fire protection has caused the security of the day to fail completely. It is worth discussing.†Hou Xiaoxun said.
At the same time, due to the lack of attention paid to security at night by the Forbidden City, night shift workers are basically retired from the retirement of the Forbidden City. There are cases of over-ageing and inadequate training of personnel. Although these people are experienced, but because they are nearly sixty years old, once they are found, it is impossible to catch up with the young and strong. This has laid a hidden danger for the night security of the Forbidden City.
"Any high-tech security equipment is controlled by people. If the alarm has been reported to the police, but the staff on duty are disapproved, this is the key to the problem." Hou Xiaoxun stressed.
"Do not think that thieves are stolen at night, and some even dare to start in the Palace in broad daylight." Hou Xiaoxun said. In the early years, there was a thieves in the Forbidden City. During the daytime, when noon staff had a meal, they opened a showcase and took away the official seal of the county magistrate. Since the occurrence of the case, the Palace Museum has stepped up security measures during the day and the exhibition department is solely responsible for it.
The same mishandling took place after the theft was completed and escaped by the patrollers. Although the patrolling officers were relatively old, at the time, as long as the police used the police dogs to recover, it was completely possible to prevent Shi Baikui from escaping the Forbidden City.
“It may be that the patrollers mistakenly thought that they had not been cleared and stayed in the afternoon. They did not expect to be stolen by the thieves and relaxed their vigilance.†Hou Xiaoxun analyzed.
Diesel generation welding machine, also known as engine welding machine, is a machine integrating the engine and the welding machine, the generator directly drives the welding machine to work by rotating the current, generally there are gasoline power, diesel and diesel power, the most commonly used, with a small power auxiliary power supply, can drive lighting and other low-power equipment. Working principle: firstly, the Diesel Engine drives the generator, and the electricity generated is used to provide AC power for the welding machine, and then the internal rectifier bridge is rectified into direct current, and finally the output is used as the welding power supply.
