Metropolitan Security New Business Opportunities, Risks and Refuges

The security of the Beijing subway has been upgraded again. The core subway station has launched a double-check mode for people. The Shenzhen police has also officially launched second-level responsibilities in the city from March 2, further strengthening social prevention and control, and cracking down on crimes. Accidents have occurred frequently, but subway construction has never stopped. The development of the city has promoted the rapid development of subway construction, and it has also brought new business opportunities to security companies. It is imminent to strengthen subway security.

Rapid development of subway construction brings new business opportunities to security companies

At present, with the rapid development of subway construction, security companies have ushered in new development opportunities. The London underground bombing in 2005 sounded the alarm for the global rail transportation industry. The domestic emphasis on rail transportation security and investment are on the rise, and the proportion of video systems in rail transportation has increased.

Chen Gang, engineer of the Chief Engineer Office of the Construction Business Headquarters of the Guangzhou Metro Corporation, pointed out: "From the perspective of subway safety threats, the possibility of an explosion in the country is very small, but the subway has a high concentration of people, especially during peak hours. There is a potential danger. A small situation may cause panic, causing people to flee blindly, crowding, or even trampling. Therefore, the security system needs to do more work in passenger flow control, early warning, and crisis management. "

The subway security field mainly includes video surveillance systems, access control systems, anti-theft alarm systems and intelligent video analysis. As a real-time image verification and historical image query tool, the video surveillance system is the core and most important part, occupying 70% -80% of the share, and the access control system is mainly for internal management of subway users, accounting for about 10% -20%, anti-theft The alarm system is relatively small.

If we simply estimate from the traditional security system such as CCTV, access control system and other weak current systems, the scale of more than 20 built cities in China, the traditional security system of each line of each city is about 100 million, and each city is calculated by 6 lines, then A total of more than 12 billion yuan. The proportion of the entire subway construction and operating costs is not very high, but when faced with extreme events, the role played is very important.

Intelligent security development of subway security

Intelligent

The subway stations and trains are public crowded places with dense crowds. If an emergency occurs, their social impact will be very great. Therefore, the trend of subway security to realize early warning, prevention, and emergency response will be obvious. To achieve intelligent monitoring, corresponding technical solutions are proposed, but the key points are all focused on image content analysis technology. This is the right direction. It can be said that the improvement of image content analysis technology is the development process of intelligent monitoring. With the development and application trend of technology, the requirements of subway security on intelligence are also increasing. The subway builder hopes to gradually transform the previous passive security into active security, thereby greatly reducing the intensity of personnel and their work. At present, the subway security construction basically puts forward the demand for intelligent video analysis, but there are not many applications in a large range. The main reason is that many intelligent video analysis functions have high requirements on the application environment, and the false alarm rate is usually Can not meet the needs of practical applications.

HD

For subway transportation, the use of high-definition surveillance to achieve more accurate and efficient video applications is obviously very urgent. This is not only to achieve high-definition real-time monitoring and video storage, but also the demand for intelligent monitoring. The clearer the image, the higher the accuracy and efficiency of intelligent analysis. Of course, to deploy HD surveillance, it must be based on a networked architecture. Due to the popularity of network monitoring, the trend of high-definition video surveillance is very obvious, and has been more and more applications. Compared with traditional D1 and CIF formats, HD can provide significantly improved video clarity and smoothness. Take the current high-level 1080P security application as an example, its resolution is 1920 × 1080, the image resolution is 20 times that of CIF video, 5 times that of D1 video, and the frame rate of 1080P can reach 60 frames per second or 60 Field / second, its fluency is more than twice that of D1 and CIF.

Common sense of subway disaster avoidance

Encountered a subway fire

On the train:

(1) Press the emergency alarm device of the subway car to report in time.

(2) Use the fire extinguisher in the car to carry out fire self-rescue.

(3) If the fire spreads, it should be evacuated to a safe compartment first.

(4) If the train cannot be operated, passengers need to be evacuated in the tunnel. At this time, under the guidance of the driver, passengers should enter the tunnel through the front or rear evacuation door in an orderly manner, or evacuate to the nearby station through the open evacuation platform.

(5) Passengers must not engage in dangerous behaviors such as sliding doors or breaking windows. Don't waste precious escape time by taking care of valuables.

In the station:

(1) Use the "fire alarm manual alarm" on the wall of the station platform or directly report to the subway station staff.

(2) In the case of thick smoke, cover your nose and mouth and escape to the ground.

(3) Pay attention to evacuating towards the bright place. In case of fire, do not take the elevator or escalator of the station.

Encountered subway blackout

(1) When the power failure occurs on the platform. Before waiting for the staff to explain and evacuate, wait in place, don't move, don't panic. The platform will immediately activate the accident lights. If the lighting cannot be restored immediately, the train that normally enters the station will be suspended, and the interior lights will be used to provide illumination to the platform.

(2) When the train is running in the tunnel and encounters a power outage, it is not allowed to leave the train compartment and enter the tunnel, and wait patiently for the rescue personnel to arrive. Rescuers will hang temporary ladders and open the doors on the non-contact rail side. Passengers should descend into the tunnel in sequence according to the rescuer's command and evacuate according to the designated station or direction. When evacuating and evacuating, pay attention to arrange in a single line, and follow the staff to evacuate along the designated route.

(3) When a large-scale power outage occurs due to a power failure in the urban power supply system, the crisis lighting system in the subway will ensure battery lighting for 45 minutes to 1 hour. If the passenger is on the platform, listen to the broadcast in the station to confirm the large-scale power outage After that, you should quickly follow the evacuation guide signs or leave the station under the direction of the staff. In other places where the light is weak in the station, you can follow the guide signs to confirm the evacuation direction.

Encounter dangerous goods in subway

(1) If an unknown package is found in the carriage, it is best to stay away from the package when the danger is not determined.

(2) When dangerous goods such as poisonous gas and venom are found, use portable napkins, clothing and other supplies to block the mouth and nose, and cover the bare skin. Quickly escape away from the source of poison. After reaching a safe place, wash bare skin with water.

Encountered train failure

(1) Evacuate from the emergency exit of the train or evacuate from the opened doors and evacuation platform according to the instructions.

(2) Please leave large items of luggage on the car during evacuation to avoid hindering evacuation.

(3) Do not jump off the track without authorization to prevent electric shock. Passengers wearing high heels should take off their shoes to avoid spraining.

(4) Walk on the designated line, do not walk on other lines or in the tunnel, and enter the platform along the steps at the end of the platform.

Conclusion

As the artery of urban traffic, the subway shortens the distance between time and space, and has become an important means of transportation to relieve traffic congestion in many large cities. In recent years, the demand for comprehensive subway security system has been strong, which has greatly promoted its development in China. But we have noticed that the other side of demand is supply, and supply is precisely the "soft spot" of Chinese security companies. There is no end to safety construction! How can the construction of the subway comprehensive security system control the investment cost, make it energy-saving, and make the whole system operation and maintenance management more effective and comprehensively improve the quality of subway service? All will be worth exploring and thinking. The development of security technology is very rapid. Metro security is in the development stage. There should be more new technologies and new manufacturers to be compatible.
