The case of Shanghai Subway Intelligent Operation Information System construction

The Shanghai Subway is considering the construction of the Business Collaboration level information system, and is planning to make a new urban rail transit plan, especially the information architecture of the networked urban rail transit.

The early construction of urban rail transit in Shanghai began in the 60 's, and 1985 started a new round of construction. With the official opening of the 1995 metro line Line 1, the Shanghai Subway has opened eight subway lines. The main business systems of these eight lines, including signal, vehicle, power supply and environment, are controlled by information systems.

In the course of more than 20 years, the management system of Shanghai Metro has been changing and the business is changing constantly, which has brought great influence to the informatization.

The change of management information

In the last century, the Shanghai subway was led by the construction headquarters to organize the construction and operation of the subway. 1999, Metro line Line 2 opened, operating business gradually increased. In 2001, Shanghai proposed a separate system for the management and investment of the national track construction, which led to the establishment of some new companies in Shanghai's rail transit. In recent years, the construction of rail transit has gradually come to an end, and large-scale construction will be completed after 2012. By then, the Shanghai Metro line will reach 500 km, all rail transit operations will gradually shift to the operation and maintenance operations. In 2004, Shanghai's rail transit was again integrated, which integrates construction, operation, maintenance, investment and industry management, and set up a new Metro group.

"Our informatization has a very big relationship with the change of the whole enterprise." "Shentong Subway Information Center Deputy Director Jintao is familiar with the development process of Shanghai subway informationization construction."

In the 90 's, the so-called "subway information is very advanced", in fact, only refers to the signal, the environment and other business control system has been world-class level, and the management of the subway has not realized the information. With the increase of subway operation and management line, the pressure of management begins to become larger, and the relationship between different lines is very complicated. At this time, the Shanghai Metro Corporation began a new round of information construction, and gradually built a number of new information systems, mainly including OA and some professional management process system.

But a few years later, there are still problems that cannot be solved: several levels of the business-from the executive layer to the business scheduling layer to the business Management layer to the decision information layer-have been difficult to get through. "The reason is that the subway construction management for many years, because of the system, the lines, the various services used by different information systems, a line of a model, this line with Alstom's, that line may be Alcatel ... The ravines between these systems are obvious and difficult to integrate. "They've been thinking about ways to solve the problem," says Jintao, "one is to rearrange the information systems to different levels; On this basis, the establishment of a business management or business synergy level of the system, especially the synergy level." ”

At present, the Shanghai Subway is considering the construction of the Business Collaboration level information system, and is planning to make a new urban rail transit plan, especially the information architecture of the networked urban rail transit. This is a relatively new attempt at home, because there are only three cities in Beijing, Shanghai and Guangzhou that really have a network of rail traffic in China. These three cities will build more than 400 kilometers of rail transit network, network operation and management of information system requirements will be very high, very urgent.

Night is more dangerous than daylight.

The subway operating system basically has two big links: one is to the equipment itself support system, mainly includes the rail works track system, the power supply, the vehicle and the signal these four systems. The other is the operation dispatch system, the Operation service System. The dispatching coordination system, in fact, is composed of station service personnel, driving personnel, station dispatcher and central dispatching personnel, who use a set of automatic train monitoring system to control the operation of rail transit in addition to the basic guarantee communication system. The dispatching business of the subway is divided into daytime dispatching business and operation end dispatching business.

Although people crowds in the subway during the day, in fact, the subway at night is much busier than daytime, the workload is much more than daytime, the maintenance, maintenance and repair of the line equipment and facilities along the road and some special construction disposal are carried out at night. "The safety of construction at night will be relatively large, which may be the problem of all subway lines, even railway traffic," he said. At night, people and construction vehicles, engineering vehicles to the scene, but also with the power supply, power outages of the construction, this environment, rail, vehicles, power supply and signal is very easy to cause conflict. "Jintao," once the conflict is a security management accident, and may be a major security incident. "Jintao pointed out that with the increase of urban rail transit, the construction task is very busy, commissioning task is very heavy, often have new test trains running between the orbit, these problems are very easy to cause major safety accidents."

"Safety issues, the Shanghai subway has been very important." Jintao said that after 2002, basically all sections, period, night in the construction, resulting in conflict of resources and coordination problems, there have been some hidden dangers and dangerous situations. "In order to strengthen management, by 2005, we plan to work together to put all the things that people want to do, all the resources to be used in a unified list, by the dispatch department unified Coordination." But 2005 years later, there is a problem: six lines, eight lines of time how to coordinate resources to ensure efficiency and security. Simple people to coordinate, has been very difficult! ”

Methods always come out, Jintao they start to use information systems to solve problems. They and the Beijing start-up technology companies, based on a unified business platform, has developed a "night construction planning and scheduling system and the subway comprehensive law enforcement system." The system through strict security locking control, so that each construction will carry out the same time period, the same line section of the car, car, car, vehicle electric conflict security check, to ensure that not due to scheduling errors and safety accidents. Since the on-line also did not appear once such an accident, the dispatch system played a great role.

Make the enterprise more flexible

"In the past few years, the Shanghai Rail Transit informatization planning focus on business automation and modernization, the executive layer and the business scheduling layer is the center of gravity." Now the focus of our planning is to make the enterprise more flexible, more scientific decision-making capacity, improve the management level and management capacity. Jintao introduced, from the corresponding system, they will be in the future of the main three levels of planning: first, the business implementation layer and the business scheduling layer of resources planning. Second, the business collaboration layer is planned. Third, planning for decision-making.

At present, the Shanghai subway system has been able to clearly see the various transfer stations daily transfer traffic. and the transfer passenger flow directly affects the line and line between the vehicle and transfer channel design, about what time will produce the peak passenger flow? How many transfer stations and how long transfer channels are needed? The system provides scientific decision-making basis for the organization and adjustment of Metro operation.

The 2010 World Expo requires the Shanghai Metro service facilities to be more informative and user-friendly, and to provide more interactive intelligence information. There are still many things to do in the construction of the information system of Shanghai Subway.
