City monitoring and alarm networking technology platform application

In the past ten years, on the basis of continuous innovation and rapid development of security technology, with the transfer of information technology brought by many IT vendors and operators to cross-industry, monitoring and alarm networking technology has been monitored by the first single closed-circuit television. Remote digital networked alarms, even extended to the current large-scale city surveillance alarms, have also led to the innovation of security technology, and the technical content and awareness of the industry have also been greatly improved. At the same time, the demand for monitoring and alarming networking platforms is also increasing. expand.

Monitoring and Alarming Networking New Technology Front-end Information Collection Technology Information Acquisition Diversification The collection of front-end information has broken through the traditional categories of video and audio information, and it has been expanded to gather peripheral information according to demand, and at the same time this information has been effectively integrated with video information. It can realize the combination of video surveillance and surrounding detection and collected information to transmit to the monitoring platform, extend the function of the monitoring platform, and at the same time extend the application range in the field of security. For example, equipment detection information, environmental quantity information, water quality air content and other information can be Collect data through the acquisition device or the corresponding sensor and transfer it to the back end through the platform network.

The complexity of front-end equipment intelligent front-end camera acquisition information, and how to ensure the validity of data, put forward higher requirements for video surveillance work. The realization of intelligent analysis technology has created a good auxiliary means for video surveillance. The intelligence of information collection can be used for alarm signals, which can identify and eliminate false alarm information to the greatest extent, and improve the quality and effectiveness of the information obtained. At present, in some industries and requirements, functions such as intrusion detection, cross-line detection, retrograde detection, target counting, congestion judgment, target protection, object detection, and license plate recognition have been implemented.

AVS: The advanced audio and video codec technology is applied in the security industry. The requirements for storage of video and audio information have the characteristics of long time and large storage capacity. The urgency of the industry application demand drives the development of audio and video codec, technology, and realization of the industry. , such as the development and development of video and audio coding boards and digital hard disk recorders.

At the same time, China's "Digital Audio and Video Coding and Decoding Technology Standards Working Group" (AVS Working Group) is targeting high-definition televisions, high-density optical storage media, and other applications such as MPEG-4 and AVC/H. Based on the 264 framework, emphasizing independent intellectual property rights, China has formulated audio/video coding technology standards, taking full account of the complexity of reality.

The new technology of transmission According to the particularity of video surveillance transmission requirements, based on the traditional transmission protocols and architectures, the security monitoring field has further innovated the transmission technology according to the requirements, such as:

1) Video/audio information transmission/switching/control technology based on TCP/IP, UDP/IP using SIP (Initial Session Protocol) as the application layer communication protocol.

2) Interconnection (secure link) technologies for various heterogeneous networks (telecom network/broad network/professional network, digital network/analog network, optical fiber/cable network, wireless network, etc.).

3) Information source encryption technology and information transmission security technology.

Video and audio display, storage, search and playback of new technologies Video and audio information display With the deepening of the informatization of the security monitoring market, the application of GIS, GPS and other geographical information in monitoring has gradually become popular, and the introduction of concepts such as high-definition, which makes it simple to meet The LCD splicing of the video surveillance signal display is difficult to meet the requirements for the complete information of the map and the real-time and accurate display of the data. The application of DLP products in some large-scale professional security monitoring projects has become a trend.

The management platform technology monitoring and networking alarm platform is designed to serve the public order, but also to ensure the safety connection and resources with the city emergency command system, urban management command system, traffic business system, digital municipal system, safety supervision business system, three defense command system, etc. Sharing, realize the scientific governance and efficient application of video surveillance resources under multi-level and multi-center architecture.

The comprehensive monitoring and alarming networking platform Tianshi integrated monitoring and alarming network management platform adopts a four-tier architecture and builds a business application platform architecture on the basis of a three-tier technology platform. The hierarchy can be described as any of the most basic architectural models of a complex, well-designed software system, such as operating system and network hierarchy models, mainstream middleware and application servers currently on the market. The video and security management platform adopts a four-tier architecture, and the lowest layer is the abstraction layer of equipment and information resources. The purpose is to provide a unified interface for devices such as different digital video, alarm, and access control devices, and to manage and configure the system as a whole. Retrieval, retrieval and information acquisition provide a unified standard, isolate the impact of the equipment on the system, and achieve access device independence; the second layer is the platform management layer, including basic services and configuration management tools; the third layer is the application layer, providing users with Specific application function interfaces for b/s and c/s structures; the top layer is the business layer, which is for security management services in different industries and provides business intelligence applications.

Pingan City Monitoring and Alarming Networking Platform Application Pingan City Management Platform (as shown in Figure 2) In addition to the common application features of the video security management platform, it also addresses the needs of safe city management and will specifically design the following applications: The multi-level management support sub-bureau - the two-level management bureau of the municipal bureau, streaming media forwarding and police station - sub-bureau - the three-level monitoring center of the municipal bureau, all levels of decentralized management. Downwards can be extended to the security team sub-monitoring center, which can be extended to the provincial office monitoring center network, forming the province's five-level monitoring network structure. Horizontally it can be extended to traffic police, fire control, urban management, urban construction, and other political and legal departments responsible for the business.

Multi-level fault-tolerant city council - two-level fault tolerance of the branch office, failure of any primary component, network or server, does not affect the normal use of another level, and meets the stringent requirements of the public security system for reliability.
