Intelligent sensing technology assists emergency command

CPS China Security Network reported that the intelligent visual Internet of Things technology incorporates the ubiquitous cameras in the city's monitoring area into the intelligent visual Internet of Things, obtains visual information through visual sensors, adds visual labels to people, vehicles, objects, and the environment, mines the target's movement trajectory and environmental change information, analyzes its behavior, and provides early warning information for the emergency command system.

The core of the construction of the city emergency command system is the goal of "professional handling of ordinary events, coordinated command of major events, and three-dimensional linkage of horizontal and vertical grids". The emergency command system consists of two major systems, one is the emergency command system for daily police reception and handling, and the other is the strategic system for coordinated command and emergency command decision analysis.

Urban "4+1" emergency command system

The emergency command system built by Bellson can be summarized in one sentence: "Based on VIDC, it realizes intelligent perception, interconnection, coordinated sharing and urban operation", referred to as the "Emergency Command 4+1 System". The four subsystems are: real-time intelligent perception of people, vehicles, objects and roads through intelligent visual Internet of Things technology; interconnection of urban information through the integration of three networks; collaborative sharing of urban information resources among officials, businesses and citizens; and intelligent city-level alarm operation.

IntelliSense

Function: Use visual acquisition and recognition, various sensors, wireless positioning systems, RFID, barcode recognition, visual tags and other top technologies to intelligently perceive urban elements and automatically collect data, covering all aspects of urban population, vehicles, facilities, resources, energy, environment, economy, people's livelihood, etc.; visualize and standardize the collected data so that managers can see it clearly visually, and use a unified and regular language for statistics, communication and storage. The video intelligent perception system of the emergency command system adopts cutting-edge technologies such as intelligent sensor technology, intelligent image recognition technology, Internet of Things technology, 3DGIS technology, and large-scale network video monitoring technology to establish an intelligent monitoring and early warning system for fire, police and disaster conditions, and realize accurate identification and precise positioning of abnormal conditions in the monitoring area, forming a three-dimensional prevention and control system that focuses on technical defense and combines human defense with technology.

Technology: Intelligent visual Internet of Things technology incorporates the ubiquitous cameras in the city's monitoring area into the intelligent visual Internet of Things. The intelligent visual Internet of Things regards each visual collection point as a perception node. Cameras and perception devices such as RFID and ZIGBEE chips constitute the perception layer of the intelligent visual Internet of Things. Optical fiber, 3G, etc. are used as transmission media, and security, fire protection, transportation and other fields are used as the application layer of RFID and data centers. Visual information is obtained through visual sensors, and visual tags are added to people, vehicles, objects, and the environment. The target's movement trajectory and environmental change information are mined, and its behavior is analyzed to provide early warning information for the emergency command system. (See Figure 1)

Interconnectivity

Function: In the field of emergency command system construction, cross-departmental and cross-platform heterogeneous integration and interconnection are the focus of people's attention. The emergency command systems of governments at all levels involve data and applications from multiple different departments. The data and applications of each department are different and independent of each other. Many departments have established their own business systems or emergency systems, and use their own standards and platforms. Integrating these data and applications together to form the next generation of government comprehensive emergency service system and improve the efficiency of interconnection between departments is the key, and it is also an important function to be achieved in the construction of a comprehensive emergency command system. (See Figure 2)

Technology: Adopting VIDC cloud unit data center technology, intelligent visual Internet of Things technology and 3DGIS visualization management platform technology, relying on the powerful network resources of telecom operators, building a system with powerful information storage, information communication and processing capabilities, as well as rapid information transmission capabilities, which can ensure the interconnection of emergency command systems of government departments at all levels, break through the business islands, network islands and data islands of departments at all levels, and realize the interconnection of the four major emergency command systems of government, industry, enterprise, county and district.

Coordinate sharing

Function: The city's comprehensive emergency command system relies on the public security command center, with the public security's 110, 119, and 122 emergency rescue systems as the core, driving the emergency rescue systems of other departments such as medical care, transportation, production safety, and disaster prevention and mitigation. The emergency management and command system is interconnected at ordinary times, with both division of labor and cooperation and coordination.

In the construction of a city-level comprehensive emergency command system, the construction of a shared platform requires coverage of basic geographic data, authoritative statistical data, large enterprise hazard source data, transportation department data, commercial enterprise distribution data, health bureau medical institution distribution thematic data and public security data, integrating the typical functions of a provincial-level comprehensive emergency command platform, and being able to respond to and manage different types of emergencies such as natural disasters, accidents and disasters, social security and public health, and effectively mobilize various emergency resources to deal with various emergencies.

Technology: Bellxin's intelligent system integration technology builds a comprehensive emergency command system, integrating remote monitoring, data collection and presentation, collaborative linkage, intelligent analysis, video conferencing, command and dispatch and other functions, supporting the hierarchical management mechanism and standardized command and dispatch process between the three levels of public security and various social public transportation departments, realizing intelligence sharing and collaborative disposal among multiple departments, meeting the needs of government, public security, transportation, health, corporate society and other departments to deal with emergencies, and providing support for emergency response and rescue.

City Operations

Function: The role of the emergency command system in normal urban operations is to conduct emergency rescue for emergencies. The state establishes regional emergency rescue organizations for safety accidents to undertake emergency rescue work for particularly serious accidents. At the request of the people's governments of provinces, autonomous regions, and municipalities directly under the central government, regional emergency rescue organizations for safety accidents shall assist local people's governments in carrying out emergency rescue work for safety accidents. The on-site emergency rescue command organization follows the principle of territorial priority and combination of strips and blocks, and is under the responsibility of the local government. According to the response level of the accident and the plan, the corresponding local government or professional emergency command organization shall form an on-site emergency rescue command headquarters, and the head of the local government or the head of the professional emergency command organization shall serve as the commander-in-chief to unify the command and coordination of emergency rescue operations.

Technology: An intelligent visualization management platform based on the combination of 3DGIS virtual reality and real-life video. The platform is a panoramic video browsing and monitoring system that integrates modern visual sensors, broadband transmission, image processing, intelligent behavior recognition, photogrammetry, 3D virtual environment, GPS and other technologies. It has changed the backward method of traditional video monitoring that relies on human eyes staring at electronic eyes and multiple cameras rolling to patrol the screen. It is a transcendence and innovation of the existing video-based security monitoring system. It is based on the 3D virtual scene of the target area. By deploying visual sensors to fully cover the target area and accurately tracking and positioning, it can display the monitoring screen and network alarm in real time. It can realize the rapid tracking, browsing and playback of the event process in the target area, perform automatic semantic recognition in real time, frame the target label and trajectory, record the alarm log, and search for the video screen that meets the conditions according to specific conditions afterwards, and call the alarm log remotely. (See Figure 3)

By adopting the technologies and products under the above 4+1 system architecture, the following goals can be achieved: on the basis of integrating and utilizing existing conditions, adopt advanced technologies to establish a highly intelligent urban emergency linkage command and dispatch system that integrates communication, command and dispatch, respond quickly to various alarms and calls for help from the public, provide people's livelihood services, ensure the timely handling of major emergencies or natural disasters, ensure the security and dispatch of major activities, and provide technical support for scientific decision-making on urban management and public safety.

Specific objectives and tasks include:

Three core technologies of "4+1" emergency command system

Intelligent Vision IoT Technology

The concept of intelligent visual Internet of Things incorporates the ubiquitous cameras in the city into the concept of the Internet of Things. Intelligent visual Internet of Things regards each visual collection point as a perception node. Cameras, RFID, ZIGBEE chips and other perception devices constitute the perception layer of intelligent visual Internet of Things. Optical fiber, 3G and other fields are used as transmission media. Security, fire protection, transportation and other fields are used as the application layer of RFID and data centers. Visual information is obtained through visual sensors, visual tags are added to people, cars and objects, and the target movement trajectory is excavated and its behavior is analyzed.

3DGIS Visual Management Platform Technology

This technology integrates modern visual sensors, broadband transmission, image processing, intelligent behavior recognition, photogrammetry, 3D virtual environment and other technologies to build a panoramic video browsing and monitoring system. It has changed the backward method of traditional video monitoring that relies on human eyes to stare at electronic eyes and multiple cameras to scroll and patrol the screen. It is a development and innovation of the existing video monitoring system. This technology is based on the 3D virtual scene of the target area, and through the deployment of visual sensors covering the entire target area and accurate tracking and positioning, it can realize real-time display of monitoring screens and network alarms.

The use of this technology can not only build a video surveillance system, but also use a virtual 3D dynamic space browser to quickly track, browse and playback the event process in the target area, perform automatic semantic recognition in real time, frame target labels and trajectories, record alarm logs, and later search for video images that meet the conditions according to specific conditions (the next generation of "intelligent video search" technology), and remotely call alarm logs.

VIDC Cloud Unit Host Technology

The technology is supported by the VIDC city-level visual intelligent analysis-storage-management data center host (VIDC cloud unit host for short), which consists of a database server, storage server, network switch, and intelligent analysis server. It has intelligent visual analysis, storage, and data management functions, and supports Web browsing. It can be directly connected to the Internet. The client does not need to install any software. As long as there is a browser, such as Microsoft IE, it can realize functions such as image monitoring, parameter setting, segmentation, and storage control.

The VIDC cloud unit host uses the latest component module processing method to build a comprehensive urban emergency command system through a flexible networking method. The supported access methods for networking include: satellite lines, PSTN, E1, IP, GSM, 3G, etc., thus forming VIDC "cloud" and "duo" to meet the needs of multi-level emergency command system construction.

The visual emergency command and dispatch platform is based on the fully open system architecture of VIDC, connecting the first-level, second-level, third-level and fourth-level units and the site through the command communication network. Starting from the innovation of video service application mode, combined with IP audio and video technology, a command center integrating multiple functions such as video command, video monitoring, video conferencing, data collection and presentation, IP telephone, etc. is established, and a unified comprehensive video command platform is established to realize video monitoring access and audio and video two-way interactive video command and access to multiple data services. The first-level, second-level, third-level and fourth-level units can implement emergency visual command and daily duty management instructions to the lower levels and report the situation of the lower levels, providing visual information guarantee means for decision-making and command of leaders at all levels.

Realize an interconnected emergency command platform

During the system construction process, based on the principle of multiple access modes and highly integrated unified message network transmission mode, the program-controlled switching communication system, electronic geographic information system, computer-aided dispatching system, wired and wireless integrated dispatching system, global positioning monitoring system, command plan system, video acquisition, image monitoring system, mobile communication system, video conferencing system and government-specific network are fully integrated to provide the basis for auxiliary decision-making and intelligent information processing, and build a basic communication platform and application platform for the city emergency linkage command system. (See Figure 4)

In the construction of emergency command systems at all levels of government, the interconnection and interoperability of emergency command systems at all levels of government can be achieved by integrating the existing resources of professional command centers such as 110, 119, 120, 122, as well as other professional police reception and handling system data resources, existing image/sensor monitoring, video conferencing systems, networks, wired, wireless and other resources.

The city emergency linkage command system integrates existing resources and resources to be built to meet the requirements of the city emergency command system construction goals and achieve the overall function of the envisioned city emergency linkage command system.
