The video surveillance system with intelligent surveillance built by Suzhou Xindao is equipped with intelligent analysis technology to realize rapid retrieval and application of image data, and then high-definition decoding on the wall to realize emergency command.
1. Background analysis
At 10:25 on November 22, 2013, the Donghuang Oil Pipeline of Sinopec Co., Ltd. Pipeline Storage and Transportation Branch in Qingdao Economic and Technological Development Zone, Shandong Province exploded, causing 62 deaths, 136 injuries and direct economic losses of 7.5 100 million yuan. Petroleum and petrochemical industry is a high-risk industry, and the State Administration of Work Safety attaches great importance to it. In 2011, the “Interim Regulations on the Supervision and Management of Major Hazardous Sources of Hazardous Chemicals” was formulated, which is applicable to the major hazards of hazardous chemicals in the production, storage, use and operation of hazardous chemicals. Source identification, evaluation, registration, filing, filing, verification, and supervision and management.
In addition to the company’s own safety production management, in recent years, domestic and foreign officials have also turned their brutal sights on various production management links such as petroleum and petrochemical exploration, oil extraction, refining, storage, transportation, and sales. Vicious anti-terrorism incidents have frequently occurred, which is very harmful to citizens. Life and corporate property pose a major threat. New management requirements are put forward for the anti-terrorism emergency command in the petroleum and petrochemical industry, and new challenges are put forward for the visualized management of video surveillance.
Two, the solution
Take the solution as an example, by building a video surveillance system with smart surveillance, coupled with intelligent analysis technology, to achieve rapid retrieval and application of image data, and then high-definition decoding on the wall, to achieve emergency command. According to the difference of business types, the petroleum and petrochemical industry can be roughly divided into three major segments: upstream, midstream, and downstream, which constitute a complete industrial chain of petrochemical products extraction, transportation, storage, production, processing, and retail, and security systems are widely used in all links.
The production and transportation links include oil and gas field exploitation, oil and gas transportation along the line, and oil and gas tankers. Most of them are in remote areas with sparsely populated people and harsh environment, and the surveillance area is wide. All kinds of theft and sabotage activities are mostly at night.
Storage refining, including oil refining and chemical plants, oil and gas depots. Need to monitor the entire business process, equipment and staff operations, the goal is to achieve alarm linkage emergency command.
Retail gas stations are large and scattered, and have a trend of networking. Oil depots, cashiers, and card sales offices are all key monitoring locations. High-definition monitoring of cash flow, employee operations, customer conditions, and entrance and exit license plates are required.
3. Anti-terrorism applications are mainly divided into the following two parts
(1) Entry and exit control
For counter-terrorism suspects, establish blacklists of personnel and vehicles at main entrances and exits, and monitor people and vehicles entering high-risk areas (gas stations/fuel depots/factories) in real time, and discover potential threats, terrorist suspects, fugitive suspects, and suspect vehicles hovering At that time, suspicious warning information (linked with video) is sent to the command center in time for the command center to quickly make police decisions and have the opportunity to control terrorist incidents earlier.
(2) Abnormal behavior monitoring
Monitor abnormal behaviors of people in high-risk areas (such as running, gathering, dispersing, wandering, etc.), and sending suspicious personnel and behavior alarm information to the command center in a timely manner for the command center to quickly make police decisions and eliminate terror in the first time Hidden dangers, to win more precious time to deal with terrorist incidents and reduce people’s lives and property losses.
The above anti-terrorism monitoring and control measures mainly apply the new intelligent analysis technology of Suzhou Xindao video:
1. Face capture
Lock the face in the dangerous area in the video that meets the video analysis conditions, and complete the face capture.
2. Face detection
The binocular stereo vision technology is used to extract the attributes of the human body, such as gender, age, height, whether to wear glasses, whether it has typical ethnic characteristics, and whether it has external characteristics such as typical terrorist suspected clothing.
3. Face comparison
Blacklisted faces are compared with the captured faces of the people you follow, such as the suspects database, the fugitives database, etc., and the real-time alarm is given according to the set acquaintance threshold, and the comparison results are uploaded to the emergency command center .
4. Individual and group behavior detection
In the video that satisfies the intelligent video analysis, the running, sudden gathering, sudden dispersal and other behaviors are automatically detected, and real-time alarms are given according to the set rules.
5. Vehicle inspection
In the video that meets the requirements of intelligent video analysis, take pictures of the vehicle and extract the characteristic attributes of the vehicle, such as license plate number, license plate color, body color, car model, car logo, etc.
In summary, the use of video surveillance intelligent analysis methods to form an invisible isolation zone in high-risk areas. Under the premise of not affecting the distribution of people, the use of intelligent video analysis can investigate the potential threats of people and vehicles entering the internal area, thereby improving the detection of high-risk videos. The early warning and prevention effectiveness of the security system in the face of terrorist attacks. Realize the intelligent alarm, emergency command, and emergency treatment of personnel and vehicles associated with terrorist attacks, so as to ensure the safety of personnel and avoid the occurrence of terrorist attacks.
Four, future challenges
In the future, the construction of the anti-terrorism system will also face the following challenges
(1) Security companies need to have a deeper understanding of the characteristics of anti-terrorism needs in high-risk locations;
(2) The integration between the emergency command information management system and the security system;
(3) The integration of intelligent analysis monitoring system and production management (SCADA) information system.
Petroleum and petrochemical counter-terrorism has a long way to go.
