Description
Technical Field
The invention belongs to the field of urban rail transit systems, and particularly relates to a system linkage control mode judgment method applied to a blocking working condition mode of an urban rail transit system.
Background
The blocking mode of the comprehensive monitoring system is defined in the engineering design specification of the comprehensive monitoring system for urban rail transit GB 0636-2010 as follows: the central-level comprehensive monitoring system receives the train blocking information provided by the signal system, automatically starts the corresponding control mode according to the situation of the train blocking position, and also can start the corresponding control mode by adopting a semi-automatic control mode and a manual control mode. And main linkage functions which the comprehensive monitoring system should have in the subway design specification GB 50157 and 2013 comprise a function of starting the ventilation equipment of the tunnel of the related station under the blocking working condition. The comprehensive monitoring system needs to realize system linkage under the blocking working condition mode when the train is blocked, and the key for realizing the blocking linkage function of the comprehensive monitoring system is to accurately judge the relation between the train blocking position condition and the corresponding control mode when linkage is executed under the blocking working condition mode.
In practical engineering application, different signal system manufacturers judge the strategy of the train blocking working condition to be inconsistent, and the contents of the transmitted train blocking information are different, so that an error exists when the comprehensive monitoring system judges the blocking linkage mode. Therefore, a comprehensive monitoring system is needed to perform modeling monitoring on two objects, namely a train and a section, and comprehensively consider states and mutual relations of the two objects to judge a linkage strategy.
Disclosure of Invention
Aiming at the defect that the prior art can not adapt to different blocking information contents of a plurality of signal system manufacturers, the invention comprehensively considers various signal information content schemes, combines different types of signal blocking information contents and an actual field engineering scene comprehensive analysis linkage control mode, and provides a system linkage control mode judgment method under the blocking working condition mode which can adapt to a mainstream signal system manufacturer in a comprehensive monitoring system.
The method takes the blocking alarm information of signal system manufacturers as a signal source, takes a comprehensive monitoring system as a main body, takes two types of data objects of trains and intervals as carriers, and adopts a set of general train blocking position judgment linkage control mode scheme to adapt to the blocking working condition of each mainstream signal system manufacturer.
The technical scheme adopted by the invention for solving the technical problems is as follows: a method for judging a system control mode of a train blocking working condition in rail transit is characterized in that a central-level comprehensive monitoring system receives train blocking information provided by a signal system and automatically judges a corresponding linkage control mode according to the situation of the train blocking position, and comprises the following steps:
the method comprises the following steps: modeling two types of data objects, namely, a train and a section.
The train object corresponds to the information of the signal system train, each train which is actually operated corresponds to a comprehensive monitoring train object, and key information of the comprehensive monitoring train object comprises a train unique identification number, a running direction, train working conditions and a blocking position; the interval object corresponds to a blocking linkage mode of the comprehensive monitoring system, each different blocking linkage control mode corresponds to one comprehensive monitoring interval object, and key information of the interval object comprises an interval unique identification number, a linkage scheme identification (linkage control mode), a corresponding driving direction, an interval maximum mileage, an interval minimum mileage, an interval current state, the number of blocked trains and a list of blocked train identification numbers.
Step two: and after the section is blocked, the comprehensive monitoring system receives the train blocking information sent by the signal system and establishes contact with a comprehensive monitoring train object.
The train blocking information at least comprises a train unique identification number, a running direction, the current working condition of the train and train position information. The current working condition of the train at least comprises a blocking state and a non-blocking state; the train position information is divided into two types according to different conditions of blocking judgment strategies of different manufacturers: track occupation information and parking mileage information.
The train jam judging mechanism of a signal system manufacturer is as follows: the train jam is recognized when an abnormal stop occurs while the train is traveling on the main line. At this time, the signal system provides actual mileage information of train parking or track information occupied by the train.
The train jam judging mechanism of a signal system manufacturer is as follows: when the train runs on a certain track or a certain section of area and exceeds the specified operation time, the train is determined to be blocked. At the moment, the special blocking condition of the slow-running overtime blocking of the train exists, so that the signal system cannot give accurate train driving mileage information and only can provide the track number or the area number where the train stays.
After the comprehensive monitoring system receives the train blocking information sent by the signal system, the train unique identification number is searched, the corresponding train object attribute value is updated, and the running direction and the position information of the blocking train are recorded into a database.
Step three: and the comprehensive monitoring system searches the corresponding interval object through the blocking information and the unique identification number in the train object.
When the information about the occurrence of train congestion is sent by the signal system in the step two, the corresponding section object is retrieved through the congestion information in the train object:
when the blocking position information in the train object is mileage information, the mileage information is adapted to the interval maximum mileage and the interval minimum mileage attribute value of the interval object, so as to determine the interval object corresponding to the blocking position of the train, and the linkage scheme configured in the interval object is the control mode of the required linkage.
When the jam position information in the train object is track information or area information, the track information (area information) is converted into starting point mileage information and ending point mileage information, and the mileage interval is adapted to the interval maximum mileage and interval minimum mileage attribute value of the interval object, so that the interval object corresponding to the jam position of the train is determined.
The track information (area information) and mileage interval conversion method comprises the following steps: and establishing mapping between the track information (area information) and the mileage interval (starting point mileage information and end point mileage information) by taking the corresponding relation between the engineering actual track (area) and the mileage as reference.
When the information sent by the signal system in the step two is the train jam canceling information, the corresponding section object is searched through the unique identification number in the train object: and searching the interval object corresponding to the train object by traversing the blocked train identification number lists of all the interval objects.
Step four: the comprehensive monitoring system carries out comprehensive judgment on the interval object and establishes the subordination relation between the train object and the interval object.
Comprehensively judging the current state of the interval object and the blocking information sent by the signal system, and updating the attribute of the interval object related to the train: a list of blocked train identification numbers, a number of blocked trains.
When the signal system sends the information of occurrence of congestion, if the current state of the interval object is that no congestion occurs, adding the unique identification number of the blocked train object into the list attribute of the identification numbers of the blocked trains of the interval object, and recording the number of the trains blocked by the interval object as 1; if the current state of the interval object is that the interval object is blocked, adding the unique identification number of the blocked train object into the list attribute of the blocked train identification number of the interval object, and adding 1 to the number of the blocked trains of the interval object; if the current blocked train identification number exists in the blocked train identification number list of the interval object, the same blocking occurrence information is repeatedly sent by the signal system, and the comprehensive monitoring system does not repeatedly process any more.
When the signal system sends the blocking cancellation information, if the blocked train identification number list of the interval object has only the current blocking cancellation train identification number, clearing the attribute of the blocked train identification number list of the interval object, and setting the number of the blocked trains of the interval object to be 0; and if the blocked train identification number list of the section object contains other train identification numbers, deleting the train identification number of the current blocking cancellation from the attribute of the blocked train identification number list of the section object, and subtracting 1 from the number of the blocked trains of the section object. If the current blockage canceling train identification number does not exist in the blockage train identification number list of the interval object, the same blockage canceling information is repeatedly sent by the signal system, and the comprehensive monitoring system does not repeatedly process.
Step five: the comprehensive monitoring system automatically executes or recommends a blocking linkage control mode to operation aiming at the interval object.
When the current state of the interval object is the unexecuted linkage control mode and the number of the train blocked by the interval object is more than 0, the comprehensive monitoring system automatically executes or recommends the corresponding blocking linkage control mode to the operation; and when the current state of the interval object is the executed linkage control mode and the number of the train blocked by the interval object is equal to 0, the comprehensive monitoring system automatically resets or recommends to the operation to reset the corresponding blocking linkage control mode.
Has the advantages that:
the invention has the advantages that: the method for judging the blocking linkage control mode can adapt to manufacturers of the mainstream signal system, avoids repeated operation of linkage of the comprehensive monitoring system when the signal system sends repeated blocking information, reduces errors existing when the comprehensive monitoring system judges the blocking linkage mode, and improves efficiency and accuracy of the comprehensive monitoring system in linkage of train blocking working conditions.
