Description

Technical Field

[0001] The invention relates to a subway signal control system, and in particular to a subway operation failure emergency linkage interaction method, device, equipment and medium. Background Art

[0002] With the acceleration of my country's urbanization process and the increase of urban population, urban subways have become one of the main modes of transportation for people's urban travel due to their safety, efficiency, large passenger capacity and punctuality. The development of subway lines has gradually changed from the station-line mode to the station-line-line network mode. This indicates that a failure at a certain point in the operation of the subway will not only affect the operation of the line, but will also further affect the operation of other normal lines, affect the reliability of subway operations, cause chaos in the operation of the line network and even threaten social security. Therefore, when an emergency occurs in the subway, it is necessary not only to "horizontally" coordinate the coordination and linkage between internal departments and professions of the line, but also to "vertically" coordinate with external linkage entities, such as public security, fire protection, medical care, government, etc., so as to quickly eliminate the hazards that may be caused by subway operation failures and ensure the safety of passengers and property.

[0003] The current emergency linkage handling mechanism for subway faults still has problems such as "single" emergency linkage subject, "different" emergency linkage mechanism, "limited" emergency linkage collaboration, and "unsmooth" emergency linkage intercommunication. In terms of linkage subjects, the subjects involved in the linkage are too simple, with single rights and responsibilities and rigid skills. In terms of linkage mechanism, linkage personnel are not standardized, linkage technical support is not unified, linkage operation mechanism is imperfect, and linkage execution guarantee mechanism is not comprehensive. In terms of linkage collaboration, linkage collaboration capacity is insufficient, there are gaps in handling and coordination, and management authority is unclear and authority is delayed. In terms of linkage intercommunication, the main problems are insufficient professional and technical communication, lack of emergency resource sharing, and emergency command errors. Therefore, how to automatically link various emergency subjects efficiently and accurately and reasonably plan and allocate emergency resources has become a technical problem that needs to be solved at present. Summary of the invention

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0050] The subway operation emergency linkage interaction method based on the service architecture of the present invention can effectively realize cross-professional and cross-departmental collaborative communication, while ensuring the independence within the profession and department, without affecting the original system operation.

[0051] A subway operation emergency linkage interaction method based on a service architecture, the method comprising:

[0052] Obtain the subway operation emergency linkage subject; the emergency linkage subject includes emergency personnel, train dispatching personnel, station staff, public security personnel, firefighters, medical staff, public transportation personnel and other subway internal personnel and social collaboration personnel and every member of the public involved; obtain subway operation fault operation and maintenance information; the fault operation / maintenance information includes equipment status information, train dispatching information, passenger flow information, station operation information, etc.;

[0053] Obtain two directly affected objects in subway operation failure: passengers in the car (P) and subway equipment (D), and map the passengers in the car P and subway equipment D to the emergency service demand area Sq. According to each independent demand, the required service functions are decomposed and collected into the emergency service demand pool Sp.

[0054] Decompose the emergency linkage subject by function, and obtain the service set so of each service that can be provided, so = {s1, s2, s3, ..., sn}; obtain the weight Won of each service demanded by passengers in the train, subway equipment and linkage objects, and the weight Wo of the service provider, and recursively match the services according to the services in the emergency service demand pool, and display the importance of the required emergency subject according to the weight of the object demand. The larger the value of Wo, the more it means that the service provider so needs to be urgently notified and quickly put into the emergency process;

[0055] Furthermore, the weight of the linkage object demand is obtained based on the impact analysis of the emergency coordination subject, as shown in the following example: Figure 1 As shown, subway operation and maintenance personnel are the most directly affected, with the highest weight, and an initial value of 10; the weights of other collaborative departments are relatively weak, with an initial value of 1; through service decomposition, the responsibilities of each emergency subject are determined, the efficiency of emergency collaboration is improved, and the "single" of emergency subjects is avoided through service search and discovery. The urgency of the emergency is guaranteed through the service weight coefficient.

[0056] like Figure 1 As shown in the figure, the emergency coordination subject analysis diagram analyzes the impact of sudden incidents on the subway and finds that equipment failure directly affects driving operations and maintenance operations, and has the most direct impact on passengers in the car, passengers in the station, as well as drivers, station staff, emergency repair personnel and other subway operation and maintenance personnel; from the perspective of passenger personal safety and reliable and safe travel, the media system needs to release various messages to notify every citizen, the transportation system needs to arrange buses, online car-hailing services, etc. to assist passengers in traveling, and the public security / fire / medical / government systems need to provide assistance for possible social security and public health issues, which requires the linkage of multiple departments; from the perspective of emergency personnel operations, it is necessary to consider the cooperation of experts in different professional fields, as well as the configuration of emergency personnel and materials, which requires the coordination of multiple professions such as vehicles, electricity, communications, signals, and dispatching.

[0057] like Figure 2 As shown, a subway operation emergency linkage interaction method based on a service architecture includes the following steps:

[0058] In step 401, the system obtains data on subway operation and equipment operation, analyzes the information, obtains analysis results, and then executes step 402;

[0059] In step 402, the system judges the analysis result, and if it exceeds the range, it will generate information and issue an alarm, and then execute step 403;

[0060] In step 403, the system analyzes the impact scope of the issued alarm through the impact analysis module, determines which operation strategies to adopt, and determines whether to execute steps 404, 405, and 406 based on equipment safety, passenger safety, and social safety;

[0061] In step 404, the system publishes equipment operation and maintenance information and organizes equipment repair, automatically recommends emergency personnel, matches emergency supplies, and plans emergency routes, etc.;

[0062] In step 405, the system releases station and vehicle operation information and organizes the adjustment of driving plans, driving emergency organization and station operation organization, etc.;

[0063] In step 406, the system releases social collaboration information, releases relevant operation information and passenger flow information to external departments, provides emergency information to public security, public transportation, medical and other departments, and releases emergency information through the public platform;

[0064] In step 407, after all emergency tasks are completed and normal operations are restored, the system records the entire emergency process in real time, and automatically generates a fault analysis report, an operation report, and a collaborative process report, and enters them into the expert database system.
