Technical Field

[0001] The present invention belongs to the technical field of rail transit design optimization, and more specifically, relates to a rail transit station area collaborative management method and system. Background Art

[0002] With the rapid development of my country's economy and the acceleration of urbanization, urban rail transit has ushered in unprecedented development opportunities and has shown a good development trend. In the next few years, my country's urban rail transit will enter a new stage of network operation. In order to better meet the needs of urban rail transit construction, the number of operating lines continues to increase and the operating mileage is also increasing. Against this background, advanced network sharing facilities have gradually been put into use and have achieved remarkable results. However, the traditional rail transit operation mode faces a series of challenges in responding to the ever-changing passenger needs and urban traffic pressure. Overcrowding at some stations has led to safety hazards, poor passenger experience, and difficulty in evacuation in emergency situations. At the same time, some stations have low operating efficiency and uneven resource allocation, which cannot effectively serve passengers in different areas of the city, especially those on the edge of the city or in the suburbs.

[0003] Therefore, there is an urgent need for a technical solution that can improve the operating efficiency of urban rail transit and reduce management costs. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a rail transit station area collaborative management method, comprising:

[0005] The stations in the rail transit station area are divided into central stations and satellite stations, and each central station is used to manage and control one or more satellite stations;

[0006] The central site allocates and manages resources for one or more satellite sites, wherein the predicted passenger flow of each site is calculated, and the central site allocates passenger flow to each satellite site according to the predicted passenger flow.

[0007] Furthermore, the central site is provided with redundant communication front-end processors and redundant real-time servers to realize data collection and data exchange of one or more satellite sites belonging to the central site.

[0008] Furthermore, a line center is set up, and the central site is controlled by the line center.

[0009] Furthermore, the driving plan is compiled through the central site and the satellite sites are monitored by video.

[0010] Furthermore, the central site and the satellite site are seamlessly connected via 100M / 1000M industrial Ethernet.

[0011] The present invention also proposes a rail transit station area collaborative management system, comprising:

[0012] A site division module is used to divide the stations in the rail transit station area into central sites and satellite sites, and each central site is used to manage and control one or more satellite sites;

[0013] The resource allocation module is used to allocate and manage resources to one or more satellite sites through the central site, wherein the predicted passenger flow of each site is calculated, and the central site allocates passenger flow to each satellite site according to the predicted passenger flow.

[0014] Furthermore, the central site is provided with redundant communication front-end processors and redundant real-time servers to realize data collection and data exchange of one or more satellite sites belonging to the central site.

[0015] Furthermore, a line center is set up, and the central site is controlled by the line center.

[0016] Furthermore, the driving plan is compiled through the central site and the satellite sites are monitored by video.

[0017] Furthermore, the central site and the satellite site are seamlessly connected via 100M / 1000M industrial Ethernet.

[0018] Compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0019] In the traditional station operation mode, if there are 30 stations, the OCC dispatcher needs to command 30 stations at the same time. In the central station operation mode, the dispatcher of the entire line commands 10 central stations. In the central station operation mode, the Longgang Line dispatcher only needs to command 10 central stations, while in the traditional station operation mode, the dispatcher has to command 30 stations. The dispatcher's command range is reduced by two-thirds, which greatly improves the efficiency of the dispatching order, especially when large-scale driving or safety problems occur, which can effectively reduce the probability of dispatchers' omissions.

[0020] Under the group operation mode, the central dispatcher only needs to command 10 central stations, while under the traditional station operation mode, the dispatcher has to command 30 stations. The dispatcher's command range is reduced by two-thirds, which greatly improves the efficiency of conveying dispatch orders, especially when large-scale driving or safety problems occur, which can effectively reduce the probability of dispatchers' omissions.

[0099] Example 5

[0100] (1) Optimization of station business management processes

[0101] Specifically, the new operation mode will select some stations on the entire line as "central stations" and other stations as "satellite stations". Under normal circumstances, the line center only controls the central station, and the central station is responsible for controlling the satellite stations; in emergency situations, the line center directly controls all stations.

[0102] The original station services of each station, including customer service, equipment control, and switch stations, were uniformly adjusted to the central station's "centralized customer service in the station area", "centralized equipment control", and "unified switch station". The central station is also responsible for the emergency response coordination of the satellite stations under its jurisdiction, and the satellite stations handle emergencies under the coordination of the central station (while retaining the ability to communicate with the line center dispatch for emergency response). On the one hand, the line center dispatch has adjusted the daily jurisdiction of all stations to only the central station, and at the same time has added the functions of central station management, satellite station management, and station area operation coordination.

[0103] (2) Optimization of equipment and facility matching mode

[0104] 1) Function matching mode

[0105] A.Central Function

[0106] The center adds comprehensive decision-making functions to the traditional equipment functions, realizing intensive management of multiple lines and network management of equipment, and realizing the people-oriented and network-intensive subway network; two-level management and control, integration of sectors and blocks; central overall control, on-site comprehensive management; integration of peacetime and wartime, efficient and resilient intelligent operation. It includes network operation monitoring, parallel scenario simulation, system situation analysis, comprehensive decision optimization, emergency consultation and command, and other functions.

[0107] B. Station Function

[0108] The central station smart passenger transport control platform is a control over the intelligent application of passenger transport, and needs to realize functions such as smart cockpit, station area collaborative management, passenger flow monitoring and prediction, driving plan preparation, video surveillance intelligent analysis, centralized equipment control, and intelligent customer service.

[0109] 2) Single system matching mode

[0110] A. Comprehensive monitoring system, such as Figure 3 As shown:

[0111] a. Central level

[0112] The central level is used to monitor the operating status of each station subsystem along the entire line. At the central level, a redundant real-time server is set up as the information center of the entire line to collect information from each station and support the supervision function of each dispatcher workstation; a redundant communication front-end is set up for real-time data collection, and the data exchange between each subsystem is completed in the communication front-end through various general protocols; a historical data server is set up to store and manage the historical data of the system to reduce the burden on the real-time server; an electric dispatch workstation is set up to realize power monitoring of the entire line; and an environmental dispatch workstation is set up to realize environmental and equipment monitoring of the entire line.

[0113] b. Central Station

[0114] The central station is used to monitor the operating status of each station subsystem in the group. In the central station AIS, redundant communication front-ends and redundant real-time servers are set up to realize data collection and data exchange of each station in the group, and support the supervision function of each operation workstation; duty stationmaster workstations and maintenance workstations are set up to allow administrators to query system information and perform maintenance operations on the system.

[0115] c. Satellite station

[0116] The satellite station is used to monitor the operating status of each subsystem of the station. In the satellite station, a redundant communication front-end is set up to collect data. The data exchange between the subsystems of the station is completed in the communication front-end through various general protocols. A duty workstation is set up to allow the administrator to query system information and perform maintenance operations on the system. The satellite station is seamlessly connected with the central station and the central level through 100M / 1000M industrial Ethernet.

[0117] C. Other equipment and facilities

[0118] The monitoring of conventional equipment in traditional subway stations is based on natural stations. The independent monitoring system does not have the function of cross-station monitoring, while the central station systems have added the function of cross-station monitoring. The monitoring management mode is shown in the following table:
