Nine core technology breakthroughs

According to the guidelines of the State Council's “advanced technology introduction, joint design and production, and building of Chinese brands”, since 2004, China has vigorously promoted original innovation, integrated innovation, introduction, digestion and absorption, and reinvention, conquering the nine core technologies such as high-speed bogies. A high-speed EMU with two speed grades of 350 km/h and 250 km/h was developed.

On May 23, Lu Chunfang, deputy general manager of China National Railway Corporation, stated that China's high-speed rail technology has achieved "leaving technology - made in China - China created" by leaps and bounds, forming independent intellectual property rights, and the high-speed rail "going out" with other high-speed rail countries There is no intellectual property dispute.

Under the "One Belt and One Road" strategy, China High Speed ​​Rail has become a business card for global and friendship. With the rapid development of China’s economy and the rapid advancement of science and technology, China’s high-speed rail is rapidly rising. Insiders said that the awareness of the “Chinese high-speed rail” brand in the world is also gradually increasing. Prime Minister Li Keqiang actively promoted China's high-speed rail technology in international trade exchanges between Britain, Romania, Thailand, and Ethiopia. The "China High Speed ​​Rail" has become a "trump card" in the hands of the Chinese. High-speed rail technology and demand are playing an important role in the international arena. It also strengthens the strategic cooperation between China and the world in international trade. The Chinese high-speed rail will also take this opportunity to rush. To the world. With the further implementation of China’s high-speed railways “going out”, the demand for high-speed rail-related security equipment will be driven to bring profits to the security market.

First, high-speed rail security involved?

According to the security composition of the high-speed rail, each part includes multiple security devices for multiple subsystems. The following are the three aspects in terms of security at the station and along the railway, security of the vehicle compartment, and electronic security in the vehicle.

(A) Station and railway security along the line

Such as entrance and exit security inspection equipment: mainly X-ray security inspection machines, security doors and hand-held metal detectors, when the access control system detects the non-carried metal items, the alarm system will promptly issue an alarm. The X-ray security inspection machine mainly detects the items in the passengers' parcels and can not open the security check. Hand-held metal detectors are used to carry out security checks on passengers after security checks are performed on passengers. To ensure accuracy. If any one of the above three types of security equipment issues an alarm, the staff can prevent it from entering the train and reduce the risk of train operation safety.

(II) Electronic fences along the railway, road monitoring, power failure processing systems, etc.

Remote control fault handling system: It is composed of outdoor high-voltage vacuum breaker, outdoor electric control cabinet, indoor electric control cabinet and a dispatch console. The relevant person in charge of the Houma North power supply section of the Taiyuan Railway Bureau explained to the reporter the working principle of the system: When the line is normally powered, the power dispatcher can collect the detection data of each station through the dispatching console and monitor the position of the switch. When the switch trip fault occurs, the dispatch console will automatically display the specific information of the fault zone. The power dispatch can be remotely operated according to the system-prompted fault zone information and the system-defined program, disconnect the line switch, and the power distribution at both ends. The rooms are powered separately. With the "GPRS" electronic "telescope", the railway system will no longer worry.

(III) Car Security

There are also many security devices in the vehicle compartment, such as fire extinguishers, safety hammers, smoke detectors, and video surveillance. In modern high-speed railcars, video surveillance is almost pervasive, not only in the carriages, but also everywhere along the platforms and railways. Once a dangerous situation is found, security personnel can clearly see through the system and immediately send someone to handle the accident. The video surveillance system is almost everywhere throughout the station. It is the eye for protecting the safety of the station, so that anyone who tries to pass through the entrance security will be exposed. In addition, monitoring methods such as organic house monitoring and disaster prevention safety monitoring are also provided. Room monitoring mainly includes power environment monitoring and safety monitoring. It will use temperature sensing and heat sensing detectors and access control systems. It will be monitored centrally in unattended substations and lighting and other important distribution equipment to keep abreast of equipment operation conditions and prevent the engine room from running out of control. . Disaster prevention safety monitoring is external monitoring. It monitors remotely emergencies such as storms, mudslides, floods, traffic accidents and other disasters in a timely manner and responds in a timely manner. It performs wireless video transmission to emergency control centers for emergency emergencies. Scheduling.

(IV) Electronic security inside the vehicle

In addition to these security equipment we can see, in fact, inside the train, in order to ensure the safe and efficient operation of the train, there are many small electronic security equipment, their effectiveness can not be ignored.

1. Smoke monitoring and alarming: If the train catches fire and smoke is produced, the smoke sensor can sense it. As the driver of the train gives an alarm, the driver knows that there is smoke in the compartment, and then immediately takes corresponding measures and selects the appropriate parking place. All the trains are non-smoking. A trace of smoke can make the train alert.

2. Train speeding alarm: The train speed sensor is installed at the bottom of the train and can accurately collect train running speed. When the train exceeds a certain limit speed, the network control system can alarm in real time and the driver will immediately adjust the operating speed.

3. Bearing overheating alarm: The train temperature sensor monitors the bearing. Once the temperature is too high, the network control system will immediately report an alarm to avoid the bearing temperature being too high, so as to avoid accidents caused by vehicle damage.

4. Seismic braking equipment: After the earthquake, the railway seismic monitoring system will analyze and determine the monitored seismic signals in time. If the pre-warning level is reached, the power of the contact network of the relevant section will be automatically cut off, and the train running on this section will be stopped by the ATC signal, and the train running in the adjacent section will no longer enter the disaster area.

(E) ATP train automatic protection system

The main function of the automatic train protection system is to automatically detect the distance between trains and prevent rear-end collisions. Under normal circumstances, trains are tracked at regular intervals and intervals. The ATP subsystem uses an automatic blocking method, that is, the track line is divided into a number of cells, called an occlusion partition. Each occlusion zone is equipped with a track circuit in which a train detection signal transmission and reception device and a locomotive signal transmission device are installed. The device automatically detects the actual operating position of the train, automatically determines the maximum safe operating speed of the train, and continuously implements speed supervision. When the interval between the two trains reaches the warning distance, the system will automatically alarm. When the alarm is invalid, the system will automatically cut off the power so that the train can not continue to drive to ensure that the prescribed driving interval.

Second, high-speed rail security market potential

With the increase in rail transit security requirements, the scope of application of security systems has continued to expand, and products have continued to be refined. Security systems have become an increasingly important part of track costs. From the perspective of the investment structure of urban rail transit construction, in a line construction project, the investment for security is over 10 million yuan. Taking the sales of security products in China's rail transit market in 2009 as an example, video surveillance accounted for the largest amount, reaching 402 million yuan, followed by access control and entrance/exit control, and 104 million yuan. Other parts included security products such as dangerous goods detection and physical protection. With the development of technology and the actual needs of subway safety precautions, the later the subway is built, the more advanced the security system and the higher the investment. This will undoubtedly bring huge business opportunities for the security industry.

In recent years, despite the global economic downturn, the rail transit equipment industry has shown strong growth. The output value increased from 141 billion euros in 2010 to 143 billion euros in 2012 and 162 billion euros in 2013. In the future, there will be an average annual growth rate of 3.4%. It is estimated that by 2018, the output value of global rail transit equipment manufacturing industry will exceed 190 billion euros. From the perspective of global market distribution, China, the United States, and Russia have the largest rail network in the world, and they are the largest market for global rail transit equipment manufacturing industry. The CIS, Middle East, South Africa, Asia, and South America quickly exhibit rail transportation equipment. Huge demand.

Although there were many problems encountered during the "going out" process. For example, although China already has the world's longest operating mileage and highest operating speed high-speed rail system, compared with high-speed rail countries such as Germany, France, and Japan, China’s high-speed rails still have room for improvement and improvement in terms of technology and standards. Laws, customs, political situations, local employment, environmental protection, etc. have also become obstacles to China's entry into the local market; another important issue is that the interest rate of **** is too high.

At present, the Chinese government has begun to set about building a platform to break the bottleneck in Asia's interconnection and preparations for the establishment of an Asian infrastructure investment bank. It promised to invest US$40 billion to establish a silk road. With the support of government policies, China’s high-speed rails will go further and further.
