In the early morning, the gate of the subway opened for the first time. At midnight, when the last bus disappeared into the depths of the tunnel during the twinkling of taillights, the first entering and last leaving were not passengers, but those who walked wholeheartedly in the 'white + black' mode In the metro operation and maintenance, when the rapid development of the increasingly smart rail transit system to inject more vitality into a city, when people begin to more efficient and convenient way to travel, it is they and those deep underground The sensors, meters, transmission and distribution equipment, monitoring and control systems, and the strong technical engineering and service teams behind make the safe, efficient, comfortable and intelligent modern metro become a reality.
With the development of urban traffic integration, the MTRC has gradually become an important link between urbanization and urban agglomeration.According to the data from the National Development and Reform Commission, it is estimated that by 2020, the number of cities approved by the State Council for the construction of urban railways will reach 50, The total mileage of traffic will reach 6,000 km.
Shanghai Metro's fun and worry
As an international metropolis, the development of Shanghai's rail transit is at the forefront of China's time. As of December 2016, Shanghai Subway opened a total of 14 lines, 336 stations and 617 km of total network operation lines. A large and dense cobweb, which carries nearly 10 million daily passenger traffic, brings great convenience to 52% of Shanghai citizens and is also loved by the public.
With the gradual growth of metro mileage, increasing number of sites, increasingly complex systems, large passenger traffic, etc., to control such a large network to ensure safe, reliable and efficient operation of the subway station at the same time, to create an orderly and comfortable passenger station environment and Convenient travel experience is not an easy task for the Shanghai Metro and a series of problems to be solved are also placed in front of Shanghai Metro operation and maintenance personnel.
First of all, the low-voltage power supply and distribution system is the power system of the subway. It not only provides traction power supply for subway trains, but also provides normal service for all subsystems (air conditioning system, water supply system, lighting system, elevator system, fire protection and security system) The power needed to operate Shanghai Subway station has many facilities and limited space, and energy, especially power consumption, is huge, and it needs continuous and stable power supply to ensure the normal operation of each system in the subway.
Secondly, with the increasing of traffic, the performance of environmental control system such as temperature, humidity, ventilation and lighting is very important for the station environmental quality.Performance and disaster situation have great impact on the fault tolerance, reliability, The comprehensive response capability also poses new challenges, while the various sub-systems in the subway station, including environmental control, have difficulty in collecting, monitoring and analyzing information because of their complexity and isolation.
At the same time, with the rapid development of the MTR, the operation of the 'sea of people' has become increasingly diminished, with the increase of manpower costs, the increase of equipment operation complexity and the increase of maintenance costs year by year, all of which are challenges for the Shanghai Subway to improve its operation and maintenance efficiency.
First seen from the brand, cooperation is ripe
Choosing an enterprise with advanced concepts, technology, service team and practical experience in deep rail transit industry is an important support for Shanghai Metro to become the leader in the rail transit industry in China, and whether today's Internet of Things, cloud computing and big data are popular With its outstanding digital innovation ability, it can speed up the integration of IT and OT technologies, making it an effective weapon for improving operation and maintenance level and operational efficiency. It has also become an important factor for Shanghai Metro to choose a partner.
Speaking with Schneider Electric as a partner, Shanghai Metro Maintenance Co., Ltd. power supply branch of the current general manager, deputy party secretary Guo Delong said that the Shanghai subway, the cooperation between the two sides is a matter of course, touched them, not only Schneider Electric innovation, advanced technology and value proposition, it is years of cooperation down, Schneider Electric Shanghai Metro demand for precision pulse and professional and meticulous service.
In the early days of the construction of the Shanghai subway, the construction unit brought Schneider Electric's products to the project. Excellent product quality, user-oriented and efficient service, so that the Shanghai subway and Schneider Electric cooperation in this regard, especially in reducing the intermediary intermediate , In addition, Schneider Electric to the Shanghai Metro to provide after-sales service and the corresponding technical support more effective: in 2005, can provide basic warranty; 2011 to provide professional testing, emergency support; 2013, upgrade 30 + site; 2014, the two sides Signed a full lifecycle service framework agreement; in 2015, to provide comprehensive hardware and services products, operation and maintenance and support; 2016, a wider range of service cooperation and service innovation. From scratch, from simple to comprehensive, from product to service , Shanghai Metro and Schneider Electric's cooperation between the increasingly close.
Upholding stems from trust, professional and innovative adherence
In recent years, the continuous development, alteration and expansion of the Shanghai subway have put forward more stringent requirements for the operators.With the expansion of the cooperation between the two sides, through a period of time to study, analyze and discuss, Schneider Electric believes that the current demand for the Shanghai Metro And challenges related to four dimensions - power distribution, environmental control, interoperability and services. In response to these problems, Schneider Electric proposed four major upgrading and service recommendations:
From the components, equipment to the distribution system to protect the Shanghai subway station subway station operation of the electricity stability and reliability and security, reduce operation and maintenance costs while improving operational efficiency;
From the mechanical and electrical equipment control system to the integrated monitoring system to achieve real-time and accuracy of the information exchange between the various professional subsystems of the 6, 8, 10, 11 and 12 lines, making the system more transparent and efficient;
· With professional software to help optimize the equipment and energy management in the subway station, help the city subway to achieve green and intelligent upgrade;
· Through a full range of life-cycle services, rich experience to help simplify service processes and reduce operational costs.
