According to the analysis of the museum's security construction system, the museum's integrated management platform must meet the requirements of openness, integration, compatibility, stability and scalability. From the perspective of openness, the museum's integrated management platform must meet the national standard 28181 agreement, be able to seamlessly connect with the business systems of public security, fire protection and other departments, and effectively form a linkage mechanism for emergencies. From the point of view of integration, the integrated pickup management platform requires the integration of all basic security systems in the museum. The million-dollar high-definition network transmission includes video surveillance, intrusion and fire alarm, access control, entrance and exit control, electronic patrol, emergency intercom, Subsystem modules such as perimeter fences and intelligent analysis are unified and integrated to realize information and data sharing interaction and automatic linkage response.
From the perspective of compatibility, the integrated management platform for lightning protection devices requires codec equipment compatible with international, optical fiber transmission industry standards and mainstream manufacturers’ SDKs. At the same time, plug-in management methods can be provided. Different access modules are compatible with equipment from different manufacturers. Independent and independent of each other. From the perspective of stability, the integrated management platform requires a better reliability design to ensure the reliability and stability of the system platform, and effectively ensure the continuity of museum users' business.
From the perspective of scalability, the multiplexer integrated management platform requires that each service module adopts modular deployment, and the screen control processing can be flexibly expanded according to business development requirements. The increase of business application functions does not need to change the original architecture of the system to fully ensure the system’s Scalability.
Characteristic analysis and technology development trend
The security features of museums can be viewed from two major aspects: one is physical defense, that is, from the perspective of physical defense, including the rationality of the division of defense zones, the effectiveness of perimeter physical defenses and environmental adaptability, and the effectiveness and reliability of physical defenses in restricted areas. , The coordination between the physical protection of the lightning protection device and the building structure and application environment. The second is technical prevention. The current characteristics of the current museum security construction mainly include: incomplete understanding of standards and norms, mechanical methods; incomplete risk identification and risk assessment, blindness in millions of high-definition network transmissions; system indicators are not clear and cannot be reached Standard and specification requirements; imperfect system planning and lack of integrity; unreasonable selection of pickup equipment, incompatible with the application environment and prevention requirements; unreasonable installation location of front-end equipment, and the multiplexer cannot achieve the preventive effect; alarm in emergency situations , Evacuation measures are not in place; the subsystems are independent of each other and the integration is low; the picture control processing equipment and system lack the necessary maintenance, and the operation status of the PIE million HD network transmission is uncertain. Museum security technology is rapidly merging with technologies such as IP, IT, HD, intelligence, cloud computing, and the Internet of Things. Independent alarms, access control, monitoring and intercom, and even fire protection have begun to integrate systems. The integration of the museum’s security system is dominated by video, from pure security to “security + management”. The rapid integration of security and business management makes intelligent visual management the core value of museum security.
Problems and shortcomings of twisted pair transmitter
Although a lot of museum security systems have been built, and to a certain extent, the museum’s safety is also guaranteed. However, some problems and deficiencies have been exposed in the development process of optical fiber transmission, mainly reflected in:
Each subsystem is relatively independent, and it is difficult to exert the overall effect
There is a lack of effective linkage mechanism among various subsystems. For example, when the alarm subsystem detects a fire, will it link the access control system to automatically open all doors? Whether it can automatically link the fire fighting system. Or when an alarm detector in a certain location alarms, can the system immediately lock the surrounding monitoring area, block the escape route of the thief from all angles, and link the public security system at the same time? If this linkage mechanism can be established, the screen control processing museum security system will be able to deal with the corresponding critical events more quickly and accurately, and reduce the corresponding losses.
Security system passive defense, difficult to actively prevent
Twisted-pair transmitters are currently part of the museum’s security system that uses video surveillance as the mainstay. Emergency events can be discovered by managers looking at the surveillance client images, which places high demands on the system and managers. On the one hand, it is impossible for the staff of the lightning protection device to stare at the big screen all the time. The PIE million HD network transmission keeps this state for a long time very easy to fatigue. On the other hand, now that the museum is building bigger and bigger, the number of multiplexer monitoring points is increasing, and it is impossible to display all the monitoring points at the same time. Screen control processing these conditions restricts the monitoring system from changing the position of passive defense, turning passive into active prevention.
Lack of effective linkage with public security, fire protection and other systems
For the museum security system, the main dangers are from man-made theft and fire. Therefore, how to effectively prevent these incidents and how to deal with them in a timely manner has become the focus of the system. At present, most security systems cannot be effectively linked with public security systems and fire fighting systems, and the pickups form a corresponding mechanism for the plan. For units such as museums, a one-minute delay may cause immeasurable losses. Therefore, the effective linkage of security systems with public security and fire protection systems is an urgent problem to be solved.
Lack of special equipment for museum systems
When building the museum security system, most of the system construction uses the design ideas and related equipment of the conventional security system. Optical fiber transmission engineering companies had to select equipment from multiple manufacturers during construction, and the lightning protection device built a patchwork system by itself. The screen control processing means that there is a lack of overall solutions for museum security systems, and the industry Special software and hardware products for special needs.
How to build a security solution
Twisted-pair transmitters At present, the safety protection system for museums mainly follows the principle of "intrusion alarm, image/sound review" and the system mechanism of "separate settings and software integration". Under the management and control of a management server, the signal processing and the conversion of various functions are realized, forming a modern integrated security protection system with a high degree of automation, intelligence, complete functions, and relatively strong comprehensive protection capabilities. A good museum security system for pickups should be a comprehensive system, which includes a set of effective management systems, a set of stable and reliable technical defense equipment, a set of practical emergency plans, and a group of dedicated security teams. ,Indispensable.
Confirmation and classification of safety protection levels
Based on the composition of the general museum and the division of various functional areas, and following the principle of “all-round, multi-level, and three-dimensional space prevention from points, lines, surfaces, and bodies”, the museum’s guard area is divided into perimeter, surveillance area, protection area, In the restricted area, there are four deep protection areas, and the screen control processing adopts a four-layer deep security system in the system structure.
Principles of dividing the depth protection area
Division of the perimeter area
The perimeter includes the outer perimeter of the building (group), outdoor perimeter and indoor perimeter.
Twisted-pair transmitter showrooms, warehouses, cultural relics restoration rooms, etc. should set up a twisted-pair transmitter "outdoor or indoor perimeter protection system" regulations, optical fiber transmission in accordance with the principle of depth protection, the perimeter of the museum includes the outer perimeter of the building , Outdoor perimeter and three-part twisted pair transmitter inside the building perimeter. As the first place where intruders may appear, the outer perimeter is also the first line of defense of the depth protection system. If possible intruders can be found on this line of defense, we hope most. The perimeter protection of twisted pair transmitters The role of this is to accurately and timely find the intrusion target twisted pair transmitter, and strive for a quick attack time. The inner perimeter protection of the lightning arrester mainly includes the protection of various entrances, doors, windows, etc. of the building wall.
Division of surveillance area
The twisted pair transmitter monitoring area is the area covered between the cordon formed by the outdoor perimeter alarm or perimeter railing and the boundary line of the protection area. In this area, security subsystems such as a video surveillance system, an intrusion alarm system and an electronic inspection management system are mainly set up for security protection, and the screen control processing ensures the safety and order of the museum. The cameras in the surveillance area mainly protect the perimeter walls, roofs and areas close to the museum. Million HD network transmission is installed with fixed cameras facing each other at a certain interval around the perimeter (preferably no more than 30 meters) to form no blind spots. In the perimeter surveillance area, the lightning protection device installs outdoor remote dome cameras at the corners of the perimeter or at an interval of no more than 100 meters in a straight line, and installs remote dome cameras on the roof. The PIE million HD network transmits surveillance buffers composed of them. Link with the perimeter alarm to form a solid perimeter line of defense.
Generally, a perimeter electronic inspection system should be installed on the outer perimeter of the museum. The inspection points of the optical fiber transmission perimeter electronic inspection management system should be within the field of view of the camera in the surveillance area, so that the safety of the inspectors can be taken into account when choosing a camera. It is a low-light and all-weather configuration. It is better for the pickups to have a dedicated video alarm device at their back end. In order to obtain usable video images, it is also necessary to set up special lighting for the security system or a certain amount of constant light on the walls, buildings, and roofs. necessary.
Protection zone division
The protection area is the area where the protection target is allowed to the public. The protective area usually refers to the exhibition hall. It has two characteristics, one is the area where the protection target is located, and the other is the area where the public frequently enters and exits. In view of the special situation of the protection area, the screen control processing of the alarm equipment in the protection area can be divided into two according to the deployment period, one is: the alarm equipment that is armed for 24 hours, and the other is the alarm equipment that is armed after the museum is closed. Mainly use video surveillance system, intrusion alarm system, pickup access control system, electronic inspection management system, explosion-proof safety inspection system and asset positioning system to protect the protection area.
Twisted pair transmitters are deployed after the museum is closed: the space alarms in the corridors of the museum can be sanjian alarms or infrared alarms, exhibition hall entrance and exit control equipment or door magnetic alarms to form the external defense line of the protection zone; The space alarm inside the lightning protection exhibition hall constitutes the internal defense line of the protection area. There are two or more technical means for the space alarm inside the protection area. We can choose passive infrared alarm and microwave alarm to cover the interior of the exhibition hall.
24-hour armed alarm equipment: alarms set in the entrance and exit to the exhibition hall, alarms inside the showcase or special alarms for specific protection targets. Passive infrared alarms or multi-latitude standing wave alarms can be installed inside the showcase. The specific special alarms for screen control processing can be weight detectors, special frame alarms, etc.
At the same time, another line of defense is formed by the wireless emergency alarms that work in the exhibition hall during the opening hours of the exhibition hall and the security personnel carry with them. Once they find suspicious conditions through optical fiber transmission, they will immediately set off the wireless alarm, and remind the control center personnel to take action through wireless channels without being alarmed Criminals. The cameras in the protection area mainly complete the macro observation of the exhibition hall and the 24-hour monitoring of the main entrances and exits. Each entrance and exit of the PIE million high-definition network transmission is handled by a dedicated fixed camera. A full coverage fixed camera is set up in the exhibition hall with a spherical remote control camera to complete the exhibition hall Full coverage monitoring. The above two types of alarm equipment combined with cameras inside and outside the protection zone, and pickups form the local depth protection system of the protection zone.
Division of restricted areas
The forbidden area of the twisted pair transmitter is the warehouse, insurance (rest assured) cabinet, repair room and other areas where the public is not allowed to enter and exit. This area is mainly set up with a video surveillance system, an intrusion alarm system and an entrance and exit control system. Restricted areas are areas where only specific personnel can enter and exit, and non-specific personnel are prohibited from entering, mainly referring to cultural relics warehouses and security monitoring centers. Lightning protection devices are generally arranged in different buildings or different floors, and communicate with the exhibition hall and the outside through dedicated channels. The design should follow the level of the partial depth protection system, and focus on strengthening the inner perimeter, passages and entrances. Protection. The access door and warehouse door of the optical fiber transmission warehouse should be equipped with a two-way card reader entrance and exit control system. For important warehouses, biometric equipment should be used to control the entry and exit of personnel, such as fingerprint recognition, palm recognition or finger vein recognition. Full real-time linkage recording.
In addition to space alarms inside the warehouse, vibration alarms should also be installed on the six walls adjacent to other areas to prevent criminals from entering through the wall. The security monitoring center is the core of the security system and should be located in the restricted area. In order to ensure the personal safety and equipment safety of the personnel on duty in the central control room, the personnel and equipment can work under suitable environmental conditions.
