High-speed rail "cake" cake seductive security ability

After the “three accidents in a row”, on July 13, the Beijing-Shanghai high-speed rail failed again. The G114 train left Shanghai Hongqiao at 9:34 a.m. and arrived at Zhenjiang South Station at a maximum speed of 130 kilometers at 11:34. It stopped for an hour and a half. Railways took a spare car to pick up passengers. The reason for this is speculative.

High-speed rail opens up the security of gold rush Since the completion of the Shinkansen in Japan in 1964, high-speed rail has taken root in many countries and regions in the world. In recent years, as a new product, the high-speed railway is entering people's lives with gradually mature technology and rapid development. When people choose to travel by means of transportation, they often compare travel time. The advent of high-speed trains has made the railway once known as the "sunset industry" rejuvenated, and has emerged. From 2007 to 2010, the development of China's high-speed rail is even more alarming, opening up the security of gold security.

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.

The current accident is all awkward. Security issues are urgent. At 11:00 am on July 12, the Beijing-Shanghai high-speed railway line was put into operation for only 13 days. The safety issue is a top priority.

The equipment used for high-speed rail monitoring is nothing more than a camera, lens, head, shield, codec, optical transceiver, matrix control equipment, linkage equipment, detectors, video equipment, remote transmission equipment, back-end access equipment, Software platform and display equipment, etc., the performance of these products must meet the high-speed rail requirements.

Such as integrated video surveillance system, from the point of view of "integrated video surveillance system" means that not only video surveillance is so simple, since "integrated" must consider and other systems integration, such as alarm systems, communications systems, control systems Wait. According to the definition of the specification, "Integrated Video Surveillance System" refers to a video surveillance system built using networked, digital video surveillance technology and IP transmission methods, providing video information required by railway business departments and information systems, and realizing network and video information. Resource sharing.” At the same time, the specification also expressly stipulates the network architecture of the railway comprehensive video surveillance system: “The comprehensive railway video surveillance system is mainly composed of video node equipment, video capture point front-end equipment, video networks and user terminals. The access node is located at each station or intermediate station along the high-speed railway and is responsible for the front-end acquisition and coding of the video; the video area nodes are located at the road office and the passenger dispatching station, and the main equipment is distributed network video recorders (NVRs), DVRs, and storages. The equipment can also be used for large-screen centralized monitoring, network management, streaming media forwarding, etc. The video core node is located in the Ministry of Railways and can call and summarize the video surveillance information.The video service of the railway integrated video surveillance system is carried through the data network, and the video acquisition. Point of the video information can be through the cable, cable Wireless transmission to the video access mode access node belongs. "

The dilemma of new technologies The harsh environment along the railway and the weather not only require the quality of the products to be excellent, but also require that the weather be clear and accurate in the case of wind, snow, and snow. Strong video analysis capabilities are the key to solving this problem. Moreover, high-speed rail video surveillance systems often need to be linked with disaster prevention systems. This requires intelligent monitoring of the monitored products for rainfall, wind speed, and water level. It is understood that there are 18 wind monitoring points, 9 rainfall monitoring points, 36 foreign object monitoring devices, 20 base stations, and 4 relay stations along the Fuzhou-Xiamen Railway. When the rainfall and wind speed do not meet the EMU operation, each monitoring station will directly transmit the data to the base station located in each railway station for computer processing and transmit it to the dispatching office of the Nanchang Railway Bureau for unified dispatch.

However, because China's video analysis technology is still in the development stage, coupled with the backwardness in hardware and software technology, it is necessary to make breakthroughs in intelligent analysis technology, and there is still a certain degree of difficulty.

Especially in the face of severe winds, dust storms, heavy snow, heavy rain and other weather conditions, these will affect the intelligent analysis system, it is easy to cause false alarms.

Concluding remarks Opportunities in time and place are in front of us. Domestic security companies should rationally analyze and truly see the needs of the market and grasp the “key” of the project. If we want to win in the high-speed rail war, “the right strategy, advanced weapons "Indispensable.
