The importance of the construction of line network command center

日期：2019-12-12

With the continuous expansion of the scale of urban rail transit network, the operation management develops from a single line management and control center to a network of multiple line management and control centers (that is, the direction of the line network command center). The main function of the integrated operation coordination command center (cocc) is to coordinate the OCC of urban rail transit.

In China, such as Beijing, Shanghai, Guangzhou, Shenzhen and other cities, rail transit line network command centers have been built, and a number of key cities are building line network command centers. The daily work of the line network command center mainly includes the review and coordination of each line operation organization scheme, the timely summary of the network real-time operation information, the rapid processing of the relevant problems in the network, and the unified dispatching and command of the network, important hub, transfer node and train operation in case of major emergencies. In order to achieve the above functions, it is necessary to establish a multi-technical support and integrated urban rail transit line network coordination command center, which should at least include the core functions of operation supervision, equipment supervision, emergency command, operation analysis, information release, etc.

Most of the urban rail transit operation and control institutions in China are built from the bottom up. Each line control center is built first, followed by the line network command center. Due to the early construction of each line control center, the information of each subsystem is collected and stored on different information platforms. A unified data sharing platform shall be established at the line network level to realize the integrated management and analysis of train, passenger flow, integrated monitoring and other operation data. The data platform system at the line network level is based on the unified line network object code and the full consideration of the system network security to build the data collection and summary model, integrate the data, and realize the long-term storage of the whole line network information.
