BEIJING-Shanghai high-speed rail train with 3G wireless network into operation this month (figure)

There is a wireless network in the train. This reporter Wang Haichin the Beijing-Shanghai high-speed rail recently passed the initial acceptance, marking the Beijing-Shanghai high-speed railway has already had the opening conditions, this month will be put into operation.　　By then, the Beijing-Shanghai drive will be less than 5 hours, "land flight."　　The "Land flight" of the Beijing-Shanghai high-speed train can achieve safe operation, and the existing line of the EMU train there are different, our correspondent recently rode the test run of the Beijing-Shanghai high-speed train, for readers to uncover new lines and new trains. >> shape head type like cheetah minus 10% resistance Beijing-Shanghai high-speed rail by the Qingdao Sifang Company designed crh380a Motor vehicle head design inspired by the Long March rocket.　　The new head length of 12 meters, more than CRH2 EMU's head length of 2.6 meters, so that the front in reducing aerodynamic drag, reduce aerodynamic noise, reduce aerodynamic lift and other aspects have better results. Initially, the researchers designed 20 types of train-head options, including fast-moving animal models, rockets, etc. Through the analysis and comparison of technical, cultural and engineering implementation, 10 kinds of head-type basic schemes were primary. After that, 5 kinds of head types are optimized, the simulation calculation and model wind tunnel test are carried out, and the two schemes are confirmed by comparison and test, and finally the prototype of the harmonious number crh380a head type is completed.　　The final concept of modelling based on the Long March rockets, the implication of the airlines, take off the potential. Trains part of the train still uses the CRH3 type EMU's "Dolphin" head type, the part uses the brand-new streamline front, the length is 2 meters longer than "the dolphin" head, looks like the running "Cheetah".　　The improved front is reduced by nearly 10% in aerodynamic resistance. >> Services Wireless fast Internet access sockets in the Beijing-Shanghai high-speed rail test run CRH380 EMU, each compartment has 3G wireless network, can provide wireless Internet access. In order to facilitate the passenger office, Entertainment needs, the car inside a lot of rechargeable sockets, part of each seat after each car socket. In the test-run high-speed train, the reporter mobile phone shows the network access signal.　　Click to connect to the 3G network. At that time, the reporter rides the emu to run in the Shandong section. Through the conversion of EMU equipment to provide 3G Internet access, you can open the Web page, browse the news. When you encounter a picture, the page is slow to open. North Vehicle group Trains bullet train engineer Li Ruichun introduced, the train each compartment has installed a wireless switching equipment, you can wireless Internet access.　　However, because the train to cross a number of provinces and cities, 3G network is operated by different telecommunications departments, different regions, terrain conditions of different network environment, the speed of the Internet will be affected.　　And aircraft can not call, can not access the Internet, can make mobile phones, Internet access will be the Beijing-Shanghai high-speed rail attract white-collar workers, business people a factor. >> Energy-saving per capita hundred kilometers of energy consumption cars only 20% trains train with LED energy-saving light source lighting, and the original halogen lampCompared to achieving the same lighting effect, a train can save 5 kwh of electricity per hour. Trains train braking, through the inertia of the train, its kinetic energy into electrical energy, back to the grid. Tests have shown that the EMU will have nearly 3000 joules of energy back to the grid at a speed of 380 km per hour.　　This will not only reduce the brake disc and brake blade wear, but also energy saving and environmental protection, reduce operating costs.　　China North vehicle technical personnel, trains EMU to 380 kilometers per hour, per capita energy consumption of hundred kilometers is less than 5.2 kilowatts, is 1/8 of the aircraft, 1/5 of the car.　　>> safety hit the "Flying Chicken" glass unscathed when the train drove to 380 km/h, the birds crashed into the windshield of the train, what would be the consequences?　　The birds are smashed and the train glass is shattered, endangering the safety of the driver and passengers. National Safety glass and quartz Glass Quality Inspection Center deputy director Shong the Dead Chicken on the accelerator to simulate the birds, when the speed reached 380 kilometers, the consequences of the impact of the standard windshield is disastrous.　　Therefore, the Beijing-Shanghai high-speed train can not use ordinary windshield. After many tests, they found new samples. The thin interlayer of this tempered glass is wrapped in a resin heart, specially designed to absorb the high speed impact.　　When the dead chicken is accelerated to simulate a bird hitting the glass, the dead chicken is smashed and the glass is intact. Eventually, the glass was used in the front windshield of the Beijing-Shanghai EMU.　　Tests have shown that 1 kg of aluminum will damage the glass, but can not penetrate, the vehicle personnel will not be harmed, 1 kg heavy birds, 20 grams of aluminum bombs can not damage the glass.　　Over the past two years, Shong and his team have done optical, electrical, shock resistance, environmental aging and other 20 aspects of testing to ensure that the Beijing-Shanghai high-speed train dedicated glass "indestructible." 500 km/h can also control the speed of the train running, indicating that the stop of the red light can not see. Will the driver of the control be in a hurry?　　Can you handle it in an emergency? Tang Tao, director of the key laboratory of rail traffic control and safety of Beijing Jiaotong University, introduced that the operation control system of the train can put more than the braking distance outside the road conditions, obstacles and other information, into a speed command, displayed on the speedometer, can be real-time instructions to the speed of the train, the driver as long as At present, CRH380 EMU control system is in accordance with the requirements of 500 kilometers per hour test, production, in the Beijing-Shanghai high-speed rail test also ran over 480 kilometers per hour.　　It should be said that the train control system is sufficient to ensure that the train at 350 kilometers per hour, 300 kilometers of safe operation.　　Passenger in distress pull "hand brake" parking when there is a dangerous situation, the passengers can only wait?　　China North Car Company in charge of the relevant officials, encountered obstacles, passengers have the ability to force the train to stop. BEIJING-Shanghai motor trains EMU each of the two ends of each car has a red handle, once the passengers found inside the car accident occurred outside, pullIf you move this handle, you will stop.　　At the same time, the driver will also be informed and determine whether the current operation of the section is suitable for parking, timely make whether to continue the processing decision.　　The driver's room also has a "driver vigilance device", the driver has a button at the foot, requiring the driver to step in a certain period of time, once the time has not been trampled, the button will send a warning, prompting the driver to respond, if the driver in a few seconds did not respond, the train will automatically stop. There are more than 1000 sensors on the train, real-time monitoring of the key systems and parts of the trains, such as temperature, speed, acceleration, pressure, insulation, etc., to collect all kinds of information of train running status, then display on the driver's room display. Once this information exceeds the limit, or if the driver does not respond correctly to the information within the specified time, the train monitoring network system will trigger the emergency braking of the train through the control system and ensure the driving safety.　　Similarly, when the train exceeds a certain speed limit, the network control system can be real-time alarm and automatic speed limit.　　For example, when the water on the track is more than 300 mm deep, it will not be suitable for train operation, the train will automatically stop.　　Dialogue (North vehicle trains EMU overall designer lei) motor deceleration 20% Reporter: Tang che trains EMU safety protection system what characteristics? Lei: Tang Che trains emu in the design of safety protection system, fault-oriented safety design principle is adopted, including fault diagnosis and remote monitoring.　　Train fault diagnosis system once discovered "unwell symptom", will prompt the alarm immediately, if has not ruled out the breakdown in the time set, the protection system will take the safety protection measure to the vehicle, carries on the deceleration or the parking.　　Reporter: In case of emergency, what emergency system? Lei: For example, a fire, the whole train ban smoking, equipped with sensors. If a passenger smokes, a cigarette butts smoke, the sensor can perceive, the driver knew the car compartment has the smoke, then chooses the suitable place to park, the division personnel will inspect where has the fire.　　Wuhan line often occurs midway stop, a check, originally is a passenger smokes.　　Reporter: Emu operating speed from 380 kilometers to 300 kilometers, what changes will bring? Lei: From the operational economic point of view, after the reduction of electricity consumption of 1/5 or so, many parts of the service life will be extended, speed down, the safety factor is very large.　　For example, the wheel, 380 kilometers per hour, may be 10,000 kilometers will wear off two or three mm, 300 kilometers per hour, may be twenty thousand or thirty thousand kilometers to wear a millimeter. BEIJING-Shanghai high-speed rail 1318 km Beijing-Shanghai high-speed railway started on April 18, 2008, from Beijing South railway station from the end of the Shanghai Hongqiao Station, the total length of 1318 kilometers, the total investment of about 220.9 billion yuan. All across Beijing, Tianjin, Shanghai three municipalities and Hebei, Shandong, Anhui, Jiangsu Four provinces, is the new China since the establishment of a long mileage, the largest investment, the highest standard of high-speed railway. November 2010 15The day tracks are completed.　　May 11 This year, the Beijing-Shanghai high-speed railway began to enter the running test phase.　　4 hours and 48 minutes of the Beijing-Shanghai high-speed rail program officially opened at the end of June operation, Beijing and Shanghai between the direct time in 4 hours and 48 minutes, the driving speed of 300 kilometers per hour and 250 kilometers per hour emu, a total of Beijing-Shanghai Direct (by stopping Nanjing South Railway station), provincial direct, along the station staggered parking three kinds of open line mode.　　The Beijing-Shanghai high-speed rail line initially opened 90 pairs of trains. 24 stations in Beijing-Shanghai high-speed railway station 23, and another contact line to Tianjin West station. The 23 stations in line are: Beijing South, Langfang, Tianjin South, Cangzhou West, Texas East, Jinan West, Taian, Qufu East, Tengzhou East, Zaozhuang, Xuzhou East, Suzhou East, Bengbu South, Dingyuan, Chuzhou, Nanjing South, Town Jiangnan, Danyang North, Changzhou North, Wuxi East, Suzhou North, Kunshan South, Shanghai Hongqiao.　　Among them, departure 5, respectively, Beijing South railway station, Tianjin West railway station, Jinan West railway station, Nanjing South Railway station, Shanghai Hongqiao Station.
