In 2011, the construction of public transportation was in full swing, the increase of bus lines, the acceleration of subway construction, and the rapid development of high-speed rail. The development of public transportation is accompanied by the safety of public transportation: the problem of subways and the rear-end collision of high-speed trains have all aroused great repercussions from society. Public security is also escalating in various security incidents. Public transport security The pace of system construction must be accelerated. This article will analyze the development status of security systems in public transportation.

The public security bus rapid development public transport system has the characteristics of dense population and large mobility. There are many factors that cause hidden dangers. How to do effective supervision and guarantee the safety of people's travel has become a positive issue for government departments at all levels since then. Against this background, security as a technical means of maintaining security has received attention from all walks of life, and bus security construction has been carried out in various places.

According to the survey, the current average security investment per bus is between 7,000 yuan and 14,000 yuan. The advantages and disadvantages of the equipment selection and the completeness of the system directly lead to the input gap. As of this year, the number of buses in the country will reach 500,000-600,000. If the average value of single-vehicle investment is 10,000 yuan, the total market for this application will be as much as 5-6 billion yuan! In addition, considering the depreciation of equipment, data transmission, and post-maintenance costs, it will cost about 4,000 yuan per car per year. If we add this expenditure, there will still be ample room for growth in the total market for bus security.

According to further analysis, not only does China have a large number of total residents, but with the introduction of the “Public Transit Priority” policy in 2005, the number of buses in various places has shown a linear upward trend. Since its development, the number of buses in each city has also been astonishing. For example, Shenzhen installed 2,500 security systems during its first phase of construction, and Xiamen completed the intelligent construction of more than 2,300 public transportation buses in the city.

Metro security market is huge According to relevant data, at present, China's subway and rail transit is entering an unprecedented period of vigorous development. In the national 4 trillion investment plan to stimulate domestic demand, urban rail transit construction accounted for a large proportion. According to the plan, the investment in urban rail transit construction in China in the next seven years will be about 600 billion yuan, which is close to the total investment of the three Three Gorges Projects. There are 33 cities in the country that formally build subways. As of today, there have been 27 cities that have been approved by the State to build rail transit projects. According to the existing plans, the total mileage of China’s subways will reach 6,100 kilometers in the next 10 years, and the planned investment for subway construction from 2011 to 2015 will reach 1.1568 billion yuan. All data indicate that subway construction will enter a period of rapid development.

With the large-scale construction of subways and the frequent explosions of foreign subways, China’s subway security construction has entered a period of rapid development. The dense population of subway stations is a high incidence of terrorist attacks and the risk of security. The subway station not only needs to have sufficient police force, but more importantly, it must build and deploy an advanced security system. The industrial application of security products in the metro area is bound to bring another business opportunity to Anji.

Rapid development of high-speed rail security In recent years, China's high-speed rail has developed rapidly and its operating speed has been continuously updated. The Wuhan-Guangzhou high-speed train with a top speed of 350 kilometers per hour and high-speed trains with a speed of 500 kilometers per hour is also under development. While the world cheers for the rapid development of China's high-speed rail, it is also paying increasing attention to the safety of high-speed rail operations. Although China's high-speed rail technology is quite mature and there are many safety and security measures, but considering the geological disasters, extreme weather, technical failures and human error, material aging and metal fatigue and other uncertainties, the safety of high-speed rail operation at all times Can not be taken lightly.

In the State Council's 4 trillion yuan investment plan, the high-speed rail is one of the top priorities. As an important guarantee for safe operation of high-speed rail, the security system has become an indispensable supporting system for high-speed railways and even ordinary railways. Relevant data show that from 2009 to 2013, the total railway investment in China will reach 3.5 trillion yuan. Zhang Shuguang, deputy chief engineer of the Ministry of Railways and deputy chief designer of the passenger dedicated line (high-speed railway), stated that according to China’s recent high-speed railway planning goal, by 2012, the total mileage of China's high-speed rail will reach 13,000 km, forming “four vertical and four horizontal”. Railway rapid passenger traffic. Many major cities in the eastern, central and western regions are included in the plan. In the next 2 to 3 years, a new round of high-speed rail construction will come.

The huge "high-speed rail cake" will bring positive influence to the international and domestic equipment manufacturing industry and the downstream security industry. According to stakeholders of the Asian Manufacturing Association, according to the calculation of the total mileage of China's high-speed rail projects of 13,000 kilometers in 2012, the investment scale of high-speed rail projects for video surveillance systems in the past two years will reach 2.6 billion yuan, if it is combined with access control and perimeter protection With other subsystems, the market size in the field of security will reach 3 billion yuan. Industry analysts said that companies engaged in monitoring, access control, alarm and other products as well as engineering construction, system integration, and management services will benefit from this. High-speed rail projects will become the next new battlefield for security companies to compete.

Airport security is concerned that the explosive power of Moscow’s Domodedovo Airport on 24th of 2011 amounted to 5 kilograms of TNT equivalent, and the suicide terrorists who detonated the bomb were mixed into the airport. On the afternoon of the 24th, local time, a suicide bombing took place at Domodedovo Airport, killing 31 people and injuring 130 people. Twenty people were seriously injured. The explosion incident has once again put aviation security at a severe test, and has also promoted the continuous development of new technologies for security applications in airports.

Airport security system mainly consists of security inspection system, video surveillance system, access control system (or entrance and exit control system), anti-theft alarm system, perimeter electronic defense system, fire alarm system, patrol system and public address system. In recent years, with the rapid development of China's economy, the air transport industry has also experienced rapid development. According to the report of the National Civil Aviation Administration, there were 121 civilian airports in China in 2000 and 175 by the end of 2010. By 2020, the total number of civil airports in China will reach 244. The rapid development of the air transport industry puts forward higher requirements for the airport's safety management. To ensure the safety of airports and air transport, major airports continuously increase security and security system construction investment, security systems are constantly upgraded, and various high-tech Security technologies and products are constantly being applied to airport security systems, and airport security construction will also usher in a new round of climax.

According to the analysis of experts, under normal circumstances, the weak electricity system construction of the airport accounts for 1-1.5% of the total investment, and security construction accounts for about 40% of the weak electricity system. Specifically, the security investment for a large-scale composite hub airport is about 100 million yuan, that for large airports is 50 million yuan - 70 million yuan, that for medium-sized airports is about 20 million yuan - 30 million yuan, and for small airports is 8 million yuan - 1000 yuan Ten thousand yuan. After the "9.11" incident in the United States in 2001, airport security has aroused the attention of governments of all countries and great concern of the international community. In order to ensure the safety of airports and air transport, major airports continue to increase security and security system construction investment, security systems are constantly upgraded, a variety of high-tech security technologies and products, especially advanced security equipment, iris, face recognition, intelligence Image analysis technology, etc., are constantly applied to airport security systems.

Concluding remarks The development of urban public transport has been growing. Due to the frequent occurrence of public transport accidents, the safety of public travel has attracted more and more attention. The construction of security systems in the public transport sector will surely become the top priority for urban security construction. For cities, only by ensuring the safety of public travel, urban security construction can be regarded as a stand. The public transportation security construction will also bring unlimited business opportunities to the security industry.
