Application of Security Technology in Urban Traffic

The urban rail transit security system is an integrated application system composed of safety precautions, electronic information, and computer network technology. It is advanced, reliable, economical, and applicable, and is an integral part of social public safety.

Broadly speaking, the safety precautions provided by urban rail transit mainly include communications, tunnel evacuation, emergency lighting, smoke prevention, fire extinguishing, screen doors, electronic inspection, fire alarms, intrusion alarms, station and train video surveillance, etc. It also has dedicated wired and wireless communication systems, police security systems, and depot/parking lot security systems, as well as police, security, security, and professional management personnel at stations and important facilities. These are the important foundations of the urban rail transit security system and can effectively ensure the normal operation of urban rail transit.

For the security industry, in the urban rail transit market, it mainly involves video surveillance, access control and entrance and exit control, dangerous goods detection and physical protection.

Video surveillance system

Rail transit video surveillance system is mainly divided into two major aspects of operation and security. It is an important part of ensuring the normal and safe operation of rail transit. The rail transit operation video monitoring system mainly deploys monitoring points in the vehicle control room, along the track, crossings, etc., and cooperates with disaster prevention and alarm systems, environment and equipment monitoring systems, power monitoring systems, screen doors or security door systems, and access control systems. Guarantee the normal operation of the rail transit system. The rail transit security video surveillance mainly includes monitoring points at railway station entrances and exits, ticket sales offices, elevators, platforms, etc., as well as rail vehicle deployment monitoring points. It integrates access control, alarm systems, etc. to timely record and grasp the logistics and human flow conditions at each station, and actively responds to them. Possible emergencies.

Access Control System

With the continuous improvement of urban rail transit construction, more and more automated control systems have been adopted, and access control systems are one of them. The application of the access control system in subway security is mainly at gateway gates, equipment rooms, track protection doors and other places. The access control system is provided for unified monitoring and management of access doors and equipment management rooms in the station equipment management area, and can also be used for staff. Attendance automated management to improve the operation and management level. The access control system has become an indispensable part of the rail transit industry and identity authentication.

Security inspection equipment

Safety inspection equipment is an important part of rail transit safety precautions. Although it continues to provoke criticism, its role is incalculable. At present there are X-ray machines, liquid detectors, explosive detectors, explosion-proof ball, air breathing apparatus, light chemical protective clothing, metal detectors, explosion-proof blankets.

The content of the subway security inspection is mainly to check whether the passengers and their luggage items carry guns, ammunition, explosives, corrosion, toxic and radioactive and other dangerous articles, in order to ensure the safety of subways and passengers. Subway security must be conducted before the passenger enters the subway. The examiner is not allowed to enter the subway. Subway security generally has three inspection methods: The first is X-ray security equipment, which is mainly used to check passengers' luggage items. The second is the detection and inspection door, which is used to check the physical condition of the passengers, mainly to check whether the passengers are carrying band-gap articles. The third is magnetic detectors, also called hand-held detectors, which are mainly used for the close examination of passengers.

The Beijing Metro Security Review is the first time in the world that security inspections have been carried out on urban subways. It has been learned that since the Beijing Subway's security inspection was conducted on June 29, 2008, a total of 2.468 billion items have been inspected, and a total of 162,600 contraband items have been seized, accounting for 0.07‰, including 1,497 military and police appliances, 30 artificial guns, 1 shell, 361 bullets, 3 bombs, 59,908 inflammable and explosive materials, 53,697 tools, dismissed 62,409 people from the station, transferred to public security 7285 people.

With the continuous implementation of relevant national laws, regulations and urban rail transit projects, during the 12th Five-Year Plan period, the construction of urban rail transit in China will enter a period of rapid development. As an important component of urban rail transit, the security system will be widely used in urban rail transit construction projects, and the security industry will also usher in new development opportunities.
