14:00 on December 16, Hisense's first rail transit signal system project-Guiyang Rail Transit Line 3 officially opened its initial operation! Line 3 is the subway line with the longest operating mileage, the largest passenger volume, the fastest running speed and the highest degree of wisdom in Guizhou, marked by the opening of Line 3. Guiyang rail transit has officially stepped into the "network era" of three subway lines from the "transfer era" of two subways.
Guiyang Rail Transit ushered in "Line Network era"
The first phase of Guiyang Line 3 is the backbone line running through the north-south direction of Guiyang City, with the longest line and the largest passenger flow. The total length of the line is about 43.03km, with 29 stations, all of which are underground stations, starting from Tongmuling (Provincial Party School) Station on the north side of Huaxi Huancheng Expressway, and finally to Luowan Station in Wudang District, spanning four administrative areas: Huaxi District, Nanming District, Yunyan District and Wudang District, covering important functional areas such as Huaxi Core area, Huaxi Park, Flower and Orchard large Residential area, Qianlingshan Park and passenger flow distribution points. These include the Flower and Orchard Community, the largest community in Asia.
The first phase of Guiyang Line 3 is an important line for Guiyang rail transit network. After the opening, many lines such as Metro Line 1, Line 2 and Line S1 under construction will be effectively connected to further improve the comprehensive public transport system of Guiyang City and lead Guiyang Rail Transit to enter the period of network operation. further improve the passenger volume and traffic accessibility of Guiyang rail transit to meet the daily travel needs of citizens and enhance travel experience.
The first phase of Guiyang Line 3 project is the first signal project undertaken by Hisense WeChat, which adopts HiM-TCS CBTC system. The design and development of the system applies advanced signal technology and security concepts, and has the characteristics of high security, high reliability, interconnection, convenient maintenance, full autonomy and so on. The level of security integrity of the system reaches SIL4. The core subsystems ATP, ATO, ATS and CI have all passed the safety certification of TUV Rheinland and obtained the CURC safety certification certificate granted by SRCC, and have been successfully listed in the catalogue of the first set of technical equipment and key core components in Shandong Province.
In the construction of the signal system of Guiyang Line 3, based on the customer-centered service concept, Hisense WeChat has upgraded its technology from the aspects of security, reliability, availability and automation to improve the automation level of Line 3. Promote the intelligent upgrading of Guiyang rail transit.
1. Advanced autopilot mode (HAM mode) has been added. HAM mode is a mode between manned driving and self-driving, which further improves the level of line automation on the basis of ATO autopilot on the existing line, reaching the level of automation level 3 (GOA3) in the industry, and realizes the full automatic operation of the whole process of getting out of the warehouse, running on the main line and returning to the warehouse without driver intervention.
two。 ATP / ATO equipment is added in the field, which greatly improves the security and automation level of the system. In the middle section of the existing line of Guiyang Metro, the driver drives manually, and the safety is completely guaranteed by manual. Line 3 provides automatic driving function while ensuring traffic safety after adding ATP / ATO equipment.
3. An integrated driving automation system has been added in the field. Automatically realize the preparation of in-and-out plan, shunting plan and departure and dispatch plan, compared with the traditional manual way, greatly reduce the workload of personnel, improve work efficiency, but also effectively avoid the hidden dangers caused by personnel operation errors.
4. ATO automatic control technology has been upgraded. The model predictive control technology is superimposed on the traditional PID algorithm, which can effectively improve passenger comfort and traction energy saving.
5. A backup center system has been added. The dual-center hot standby quadruple redundant working mode is formed with the ATS system deployed on the urban rail cloud, which greatly improves the reliability of the signal system.
6. An emergency dispatching command station has been set up in the control center. Tailor-made for Guiyang Line 3, it can provide dispatchers with emergency command after the failure of central equipment and even the paralysis of the whole signal system, and effectively improve the security of the system and the ability of emergency scheduling and command.
7. A number of upgrades have also been made in signal system maintenance and condition monitoring. The sealed waterproof switch machine with better performance is adopted to collect the representation state of each switch machine pulled by two machines separately, to add the monitoring of the leakage cable of wireless transmission medium, the real-time monitoring of the wireless communication quality of the car and the ground, and to enrich the monitoring means and monitoring contents. ensure the healthy and stable operation of the signal system.
In addition to technology upgrading, Hisense also has high standards and high quality to build a signal system delivery model. During the construction period, the project team continuously optimized the commissioning plan and implemented various safeguard measures in strict accordance with the objectives of the overall construction plan. The trial operation authorization was obtained for 47 days of bullet train commissioning, and each authorization was completed ahead of schedule. During the trial operation, the failure rate of the core equipment of the signal system is 0, which ensures the smooth opening of Line 3.
With the smooth opening of Guiyang Line 3, Guiyang rail transit officially opened a new chapter in the "network era". For Hisense, this is a breakthrough of the autonomous signal system in the urban rail industry, and a milestone in the field of urban rail transit signals. An enterprise and a city once again achieve the same frequency resonance and common growth.
Hisense and Guiyang resonate and grow together on the same frequency
Hisense has been linked with Guiyang for a long time. Since 2009, Hisense has been deeply involved in the construction of Guiyang smart city, providing Guiyang with urban transportation, rail transit, public transport, public safety, smart neighborhoods, smart buildings and other products and solutions.
In the field of urban transportation, it will help Guiyang to build an intelligent monitoring and command system for road traffic management, and undertake signal tuning services such as Guanshan Lake District, Huaxi District, Baiyun District and Jingkai District. This year, the ADB won the bid for the development of a new urbanization intelligent transportation system in Gui'an New area in 160 million to help build a real-time perception system of dynamic traffic information in Gui'an New area.
In the field of rail transit, lines 1, 2 and 3 are all blessed by Hisense technology. In particular, the layout of Line 1 and Line 2 is "face-to-face Guiyang". Citizens can take the subway by facial scanning, and the number of users has exceeded 3 million since it was opened. And landed at Hisense's first wisdom station on Line 2, the Provincial Medical Station, which starts in 4 minutes and clears passengers in 10 minutes; 20 security events are monitored and alarmed in video AI seconds; 15 core business independent operation scenarios.
