Hangzhou Airport Rail Express Signal System will be opened to open the operation and expert review

Author:Hubei Window Time:2022.09.01

Recently, the Hangzhou Airport Rail Express signal and platform door system successfully passed the unit engineering acceptance and expert review, and the construction of the Hangzhou Airport Rail Express has taken an important step.

The total length of the Hangzhou Airport Rail Express is 59.14km. It runs through the central urban area of Hangzhou, starts from Xixi Station in the west, and in the east to Yongsheng Road Station, connects Hangzhou East Railway Station, Hangzhou West Station, Xiaoshan International Airport and other transportation hubs. It is a key construction project in Zhejiang Province. After the opening of the airport rail express line, it will provide great convenience for the traffic of Hangzhou citizens.

The lead is the net, the king of transfer

After the opening of the Hangzhou Airport Express Line, it will transfer with 9 subway lines, including Hangzhou Metro Line 3 (Railway West Station), Hangzhou Metro Line 5 (Chuangjing Road Station), Hangzhou Metro Line 10 (Wen San Road Station Station ), Hangzhou Metro Line 2 (Shentang Bridge Station), Hangzhou Metro Line 1, 3 (West Lake Cultural Plaza Station), Hangzhou Metro Line 4 and 6 (train East Station), Hangzhou Metro Line 9 (Royal Dao Station Station ), Hangzhou Metro Line 1 and 7 (Xiaoshan Airport Station), Hangzhou Metro Line 7 (Yongsheng Road Station), etc. The subsequent transfers will also be transferred to multiple stations (Haichuangyuan Station, Xixi Wetland North Station, Gengwen Road Station, Zhixing Road Station, Pinglan Road Station) in the long -term line. It is the new "transfer king" after Hangzhou Metro.

Quality security supervision, deepen the line

In the midsummer, the supervisors of the rail signal department of the Hangzhou Construction Engineering Quality and Safety Supervision General Station were not afraid of the heat of the heat, and actively organized the participation of the parties to the construction of the front -line inspection. Through in -depth scenes, opinions and suggestions on the construction quality of the signal equipment and platform door installation. They often say: "We are the" Guardian of the Engineering ', go deep into the scene, keep the safety port, and control the quality. In the most basic and most important safety and quality of urban rail transit projects, we must hand over a full answer sheet " Essence The supervisors of the Mass and Safety Supervision Regulatory Station's rail signal department inspect and supervise the quality problems and safety risks of the construction site on a regular basis, and keep an eye on the implementation of the rectification of hidden dangers. Adhering to such a work style, the entire signal and platform project of the airport express line from starting to completion, no safety and quality accidents occurred.

Safe driving, brain center

The signal system is the brain of train operation and is the key to ensuring driving safety. The signal CBTC system uses the two -way data communication of the train and ground equipment, so that the "brain" of the train can obtain the ground information and other train operation information in real time. , "The brain" calculates the speed curve of the train operation in real time, adjusts the operating speed, running spacing, etc. in real time, and achieves accurate fixed -point parking and efficient operating organizations. There are many innovations at Hangzhou Airport Rail Express:

The airport express line is the first subway line that cross the center of Hangzhou and operates up to 120km/h. The running time is within 60 minutes.

The airport express train uses 4 movements, 2 drags and 6 sections of the type A car, which can accommodate 1800-2500 passengers. The carriage is strong and the noise is small. For the first time on the train, the luggage rack is equipped with a mobile phone USB charging port for the first time on the seat, and the carriage is equipped with a mobile wireless charging platform for the first time.

The Jingjiang parking lot and front vehicle sections of the airport express are the first vehicle base in Hangzhou Metro with ATO/ATP (autonomous driving, protection) function. It can effectively improve the capacity of the train entry and exit section, ensure density of receiving vehicles, and shorten the interval.

For the first time, the airport express signal system is equipped with multiple means such as cable missing monitoring to monitor the signal equipment in real time to ensure that the maintenance personnel can discover the equipment abnormality as soon as possible, deal with it in time, and prevent it before they occur.

The airport fast line has added a fast -moving running operation mode, providing higher -level flat peaks and peak hours of line operation and train services, making the operational efficiency higher, which greatly shortens the space -time distance from the main urban area to Xiaoshan International Airport.

Work overtime, strengthen nodes

The construction period of Hangzhou Airport Express is extremely tight. The China Railway Construction Electrification Bureau and the construction units and other parties twist into a rope. After discussions by multiple parties, the innovative construction method of signal cable was set up in front of the rail paving. The cable laying work is advanced, effectively avoiding the serious cross construction, and the signal engineering is finally completed as scheduled.

Scientific and technological innovation, self -improvement

During the construction process, due to difficulties such as tight construction period, complex construction conditions, and wide construction area, the construction party established a scientific and technological innovation team. As of now, 11 practical new patent authorizations have been completed, and 5 computer software works have been authorized, which has greatly shortened the construction period, and provided multiple signal system installation guidance for the later construction of Hangzhou Metro.
