With the improvement of people's living standards, more and more people are interested in the activities that are centered on health. The construction of stadiums and stadiums can improve urban functions and improve urban tastes. It has a wide range of needs. After China successfully bid to host the "2008 Olympic Games" and the "2010 Asian Games," there are still a large number of stadiums that need to be built and reconstructed. The promotion of green sports and the promotion of green, scientific, and digital development of sports venues also mentioned a new height, among which the monitoring and construction of stadiums and stadiums is extremely important. At the same time, with the continuous development of science and technology, technologies such as high-definition cameras, video encoding, wireless transmission, and dual-system hot backup have been widely used in the field of surveillance. Therefore, under the new social background and technological background, the monitoring of stadiums and stadiums is no longer the traditional sense of video surveillance, but a comprehensive set of security systems. In addition to the basic functions such as video browsing, video storage, and remote control, it can also implement alarm linkage function, behavior analysis function, GIS function, perimeter prevention, professional statistical statements, emergency command system interconnection, and “three-in-oneâ€. Take care of the police system interconnection and many other personalized features.
In response to the demand for highly integrated and intelligent stadium monitoring, ZTE has been the first company in the industry to put forward the concept of “universal monitoringâ€, which includes six levels of meaning: monitoring and business integration, signaling and media integration, analog and digital Unified, unified wired and wireless, unified equipment and network, unified product and engineering.
The surveillance and business unified stadium monitoring system needs to integrate various services such as video, voice, data, alarm, intelligent analysis, resource management, and dispatch and command. The monitoring business functions are realized through professional clients, WEB clients, mobile terminals, multimedia exchange units, and large-screen display systems, and are used by authorized business personnel, and have the functions of real-time remote media information viewing, history information recall, and other related functions. Personnel business use requirements. The system management function is implemented through the management client, which is used by the system administrators to implement functions such as device management, user management, and system maintenance, ensuring the normal operation of the system.
In addition to the above businesses, it is also necessary to integrate the following businesses:
Power environment monitoring system: monitoring power supply equipment, air conditioning, temperature and humidity, smoke fire, flooding and other power environment objects in the stadium, and combining video surveillance as an alarm linkage.
Electronic map system: through the combination of monitoring system and GIS, display the position of the camera on the electronic map, and prompt the alarm information, the user can view the working status of all the cameras in the monitoring system and intuitively and quickly view the geographical information of each monitoring site. According to the situation, quickly switch to the corresponding camera surveillance area to provide a scientific basis for the remote command.
Perimeter defense system: By installing sensors such as infrared radiation and vibration cables, an invisible barrier is formed around the important area of ​​the stadium, which can sense illegally intruded objects and alert the staff in time.
Intelligent access control system: The intelligent access control system adopts advanced radio frequency technology and other advanced technical means to replace the traditional key opening method, which effectively solves the problem of confusion in key management of stadium lounges, duty rooms and monitoring centers, and realizes access to personnel at the same time. Scientific management.
Intelligent analysis system: With intelligent video analysis services, you can choose to integrate smart image technology, including flow statistics, perimeter prevention, crowd gathering, stolen items, and legacy items, to provide evidence for riot protection and anti-terrorism in venues and for special situations. Timely alarm.
At the same time, according to the business characteristics of different regions and different types of venues, the system also needs to be able to provide users with quick customized development services to meet the special needs of users and achieve the sharing of the user's existing system resources.
Signaling and Media The uniform stadium monitoring system needs to be designed based on standard coding compression standards, media transmission protocols, signaling interaction protocols, and system interconnection protocols.
At the monitoring site, high-efficiency H is used. 264 compression technology, which realizes digital encoding and compression processing of media information, compresses content-rich media streams to 2M or less, making it possible for media information to be transmitted on the Internet. The media stream occupies high bandwidth, and the interruption of the media stream will result in the loss of local surveillance video of the user. The important level is relatively low. The signaling stream occupies low bandwidth. If the signaling flow is interrupted, the entire system may be paralyzed and the reliability of the signaling information may be high. More important. The system adopts separate processing mechanisms for media streams and signaling streams to prevent the central management platform from being impacted by media streams, which greatly improves the reliability of the system. At the same time, it is necessary to support the interconnection of heterogeneous systems and achieve resource sharing. The system reserves interconnection interfaces to facilitate interconnection between systems. In addition, it interfaces with other management systems through standard system interconnection protocols (such as OA systems).
The simulation and digital uniform sports stadium monitoring system needs to realize the coexistence of analog monitoring technology and digital monitoring technology, and realize the diagnosis-digital upgrade of analog system.
Because many stadiums are currently using analog monitoring networks, when meeting certain large-scale events, it is often necessary to connect monitoring systems of multiple stadiums. It also requires multiple security systems and management systems to achieve docking. This requires The original system was reformed and the monitoring-analogue monitoring system was connected to the same digital system. The system structure design needs to have an open system that can integrate existing analog or digital monitoring systems and protect user-owned monitoring equipment investments. To realize the unification of analog and digital surveillance, it is necessary that the decoding unit of the stadium monitoring system can realize the function of mutual control with the mainstream analog matrix. In the same system, the user can select the analog matrix or digital matrix (multimedia exchange unit). Control operation.
The wired and wireless unified stadium monitoring system needs to realize seamless business connection between the wired network and the wireless network, so that monitoring can be performed at will. As shown in Figure 1.
Some areas of the stadium cannot be wired or the wiring cost is high, such as the height of the ceiling of a large football stadium. Therefore, the on-site monitoring image information can be uploaded to the monitoring system through the wireless network, enabling the flexible deployment of on-site monitoring equipment and effectively solving the monitoring site. The problem of lack of network. At the same time, users can also use the mobile phone terminal with data services to query, view and control the live video in real time and monitor the situation at any time and anywhere. There are many ways of wireless transmission, and the main methods used in stadiums are Wi-Fi and 3G transmission.
The unified stadium and stadium monitoring system for equipment and networks requires high-performance network management and supports hierarchical and domain-based management modes to ensure the reliable operation of the system.
Stadium monitoring and monitoring - cover a number of security operations, involving all kinds of monitoring equipment needs management, stadium monitoring system provides equipment management, user management, image management, status management, security management, alarm management, storage management and other powerful system maintenance And management functions will bring great convenience to the use and maintenance of the monitoring system. At the same time, the monitoring system divides the management domain according to the organizational structure. The domain administrator is responsible for managing the system devices and users in the domain, performing state monitoring and fault maintenance on the devices in the domain, and grouping and managing the users in the domain, and assigning to each user group. The difference in authority, to achieve the user's hierarchical management capabilities, multi- venues will be fully applied when hosting large-scale events.
The construction of a unified stadium monitoring system for products and engineering requires the integration of various types of cameras and multimedia access units, as well as integrated design of products, solutions, construction, and maintenance. For example, network security protection, system disaster recovery backup, and device cabling According to local conditions and so on.
Concluding remarks The characteristics of large-scale stadiums are large scale and high grade, and the level of guests and athletes they receive is also high. Therefore, the security requirements are particularly high. When stadiums hold large-scale competitions, opening, closing and other large-scale activities, they include venues for training areas, competition venues, various lounges, and visitors, athletes entrances and exits, passages, important equipment, parking lots and other places. The monitoring systems are all It is an important means of security in the stadium. Based on the "Unified Surveillance" concept of security monitoring, the stadium monitoring system will also provide safety protection for the stadium's usual fitness, exercise, leisure, information services, convention and exhibition services, and daily work to solve the facility safety, security of items, security, etc. A series of problems can simultaneously provide features such as convenient management, lower costs, and simplified network equipment, thus laying a solid foundation for the construction of intelligent sports venues.
