“Spring Festival” is a word known to all women and children in China. It carries countless wanderings of Acacia. At present, railway transportation is still the main mode of travel for medium- and long-distance traffic in China. Especially during the Spring Festival, the pressure on rail transportation has skyrocketed. The safety, timeliness, stability, and ability of rapid response to emergencies have become a matter of national concern. focus. In the 3G era, the application of advanced technology such as video to the actual use of emergency command and dispatch of railways will greatly increase the reliability and operational efficiency of the emergency command and dispatch system.

Railway transportation during the Spring Festival is stressful and lasts for a long time. The security issue has become the key to the “Spring Festival Movement” and is known as the largest and periodic human migration in human history. In 40 days or so, there will be more than 2 billion people flow, which accounts for 1/3 of the world population. China Spring Festival was selected by the World Record Association of China as the world's largest cyclical transportation peak, creating many of the world's best and most of China. With such a large-scale population flow, the complexity of its security dispatching command can be imagined.

In addition to the pressure of transportation, the complexity of China's railway environment has also created a great security risk. Our country has a vast territory, complex terrain and climate, which has led to a wide range of railway disasters, many types and frequent occurrences. The distribution of railway disasters has spread throughout the country. Basically, all railways are affected by disasters of different degrees. Especially during the Spring Festival season, the frequent occurrence of Blizzard's freezing disaster has caused great difficulties for the safe transportation of the railway.

In addition, during the Spring Festival each year, the illegal behavior of the Cattle Dashing Party, indiscriminate fishing, fish-smelling, and fish-swept fishing have added to the complexity of the security situation. Safety is the lifeline of railway transportation, especially during the Spring Festival. For a long time, the railway department has invested a lot of manpower and material resources to ensure the safety of transportation during the Spring Festival.

In recent years, with the rapid development of the economy, the size of the floating population has been rising year by year, and the security of railway transportation during the Spring Festival has become increasingly difficult. With the increasing popularity of video surveillance and video command and dispatch applications, more and more technological factors have been added to railway transportation security. Technology guarantees railway safety has become an irreversible trend.

3G video application makes railway command and dispatch more flexible The traditional railway dispatching recording system can ensure that the instructions of the railway dispatching and commanding are correctly and timely recorded, and improves the management department’s information distribution, collection, processing capacity, and linkage response capabilities, but this is There are obvious deficiencies in responding to emergencies, that is, it is impossible to understand the situation in a timely and comprehensive manner and is not conducive to the formulation of effective measures. With the increasingly prominent importance of unified dispatch in railway applications, the video command and dispatch system has become a “darling” of railway security.

The video command and dispatch system integrates video surveillance and video conferencing. It also joins the application logic of command and dispatch, and forms a set of communication systems that can perform both one-way monitoring and two-way communication, in order to integrate closely with the user's business processes. The user's favor. Compared with traditional video surveillance systems, the video command and dispatch system can not only remotely check the status of the scene through the monitoring system. When there is a problem in security, the relevant personnel are notified by telephone or voice to handle and solve the problem, and the emergency meeting can be quickly organized so that Specific conditions establish timely and effective measures.

Since its inception, 3G technology has attracted people's attention with its outstanding flexibility. With the issuance of 3G licenses, the application of 3G mobile video has become the focus of research and development for many video vendors. The continuous improvement of 3G networks has enabled 3G video to be rapidly promoted to the three police forces, power industry, disaster emergency command and dispatch, civil aviation management, urban public utilities (gas, tap water) and municipal management.

In the process of railway transportation, affected by many factors such as weather, geology, and human factors, the location of the incident and the situation on the site are uncertain, and the complex and changeable on-site environment is not conducive to the rear command and dispatch center to make timely and accurate decisions. The application of 3G technology can enable on-site personnel to pass the event development status back to the dispatching command center at the first time, and can conduct on-site consultation with the dispatch center to promote the timely issuance of effective programs and greatly increase the processing efficiency.

Railway applications will provide a broader market platform for mobile video communications. With the rapid development of the railway transportation network, video applications are indispensable for both the daily transportation of railways and the internal management of railway departments.

According to related data surveys, China’s average annual railway transportation disruption caused by various disasters has reached 100 times per year, accumulating 1,0002,000 hours, and the highest peak ever reached 211 times. The disaster road section has accounted for more than 20% of the total operating mileage of the whole road. There are still many line disasters in a latent state, which seriously threaten the safety of the railway. In order to ensure the safety of railway transportation and actively respond to emergencies, the application of video monitoring and dispatching is very necessary.

For the internal management of railways, monitoring and dispatching command is also essential. The railway locomotive depot has a large area, many departments, complex personnel, and undertakes important tasks such as vehicle scheduling, maintenance, and overhaul. Therefore, to ensure normal order and efficient work, unified command and dispatch are very important.

The traditional railway emergency command and dispatch system is integrated with 3G video technology, which makes the original voice and video technology icing on the cake, and fully meets the demand for flexible command and dispatch command of railway transportation. As a nationwide super market, the railway application market will greatly expand the application of mobile video communications and enhance the practical value of mobile video. The large-scale application of mobile video communication in railways will become a “living sign” for its industry applications, which will effectively stimulate the further development of the industry application market.

Since the release of 3G licenses in 2009, the application of mobile video has been the focus of video vendor promotion, but the market effect is not satisfactory. In recent years, with the rise of video command and dispatch, the mobile video command and dispatch system created by the combination of 3G technology and video command and dispatch has become the new darling of the public security and transportation industries. The practical value of mobile video communication is increasingly prominent. Experts in the projection era believe that the vigorous promotion of mobile video communications in the railway field will become an “accelerator” for its application development. Whether at the propaganda level or the practical level, mobile video communications will achieve leapfrog development.
