The invention discloses a method and a tool for dividing a line section of a subway CBTC system, which relate to the technical field of subway signal systems and comprise a signal plane map reading step, a line section boundary determining step, a line section dividing step and a line section adjusting step.
Description
Technical Field
The invention relates to the technical field of subway signal systems, in particular to a method and a tool for dividing a subway CBTC system line section.
Background
With the acceleration of urban rail transit construction process and the gradual increase of subway construction projects, a common subway signal System CBTC (Communication Based Train Control System) System carries out real-time and large-capacity bidirectional information interaction between a Train, a ground and a dispatching center through wireless Communication, and realizes the safe operation and Control of a Train.
The subway CBTC system has the advantages that each subsystem in the subway CBTC system can realize supervision and control on the train only by knowing the position information of the train, so that the train position information of information interaction among the subsystems can be accurately expressed and accurately corresponding to the train position information in the line network, wherein the train position information is described through line sections in the line network, and higher requirements are provided for the uniqueness and the accuracy of the line sections in the line network. In one line, line sections are line datamation and are the basis for providing line electronic map information, and the uniqueness, the completeness of line coverage and the practicability of line sections applied by each subsystem need to be considered when dividing the line sections. If the line section is too long, the total length of the detected train occupying the line section is too long, and the tracking distance between the front train and the rear train is too large, so that the traveling efficiency is too low. If the line sections are divided to be too short, the length of the train exceeds the length of a turnout section, so that the condition that one train occupies 3 line sections can be caused when the turnout section displays that the line sections occupy, and meanwhile, when the train occupies the line sections in sequence in the turnout section, if a certain line section is too short, light train jumping can occur, namely, delay occurs when axle counting equipment beside the track detects that the train occupies or delay occurs when a monitoring system receives messages, so that the condition that the line section is not occupied yet and the train runs through the line section can be caused when the monitoring interface detects that the line section is not occupied yet. Therefore, the division of the line segment should not be too long or too short, and the requirement of each subsystem should be satisfied.
In the existing patents and papers, documents for dividing line sections are relatively few, and in the published documents, a paper document named as "CBTC system line data automatic generation research" provides a line section division principle of a subway CBTC system, which divides the line sections by taking a turnout point, a line end and a direct connection point (axle counting) as end point types of the line sections, and the line sections obtained by the division scheme can satisfy most functions of subsystems, but the technical scheme has the following defects: 1. there may be a line segment directly associated with 2 switch points, making the location of the line segment ambiguous and unable to identify which switch range the line segment belongs to, causing errors in the calculation of switches by the associated subsystem. 2. The length of the line section is too long, so that the driving efficiency is too low. 3. There may be one line segment containing 2 semaphores, so that the semaphore guard segment is repeated.
At present, a subway CBTC system is widely applied to urban rail transit construction, large-scale line opening is faced, and it is very important to provide a subway CBTC system line section division method and a tool which are widely applied, can meet the scheme of each subsystem and can quickly divide line sections.
