Determining method and device for radio block center (RBC) control train number calculation parameter

Abstract

The invention discloses a determining method and device for a radio block center (RBC) control train number calculation parameter. The determining method comprises the steps that statistics on the maximum simultaneous use condition within the jurisdiction range of an RBC from a station to a departure line at the same moment is conducted; according to the character of the station, the operation organization characteristic and the passed car ratio of the station, by referring to the maximum simultaneous use condition, obtained through statistics, from the station to the departure line, fitting analysis is conducted on the maximum simultaneous use ratio from the station to the departure line through normal distribution, and the value of the utilization factor k is determined while a station track of a CTCS-3 level motor train set can be stored within the control range of the RBC used for calculating the control train number; and / or according to train operation direction information and a track blocking system, the number T<RBC-RBC> of the switching position within the control range of the RBC and the control range of an adjacent RBC is determined. The RBC control train number calculation parameter can be better determined, and the accuracy and effectiveness of control train number calculation are improved.

Description

technical field [0001] The invention relates to the technical field of high-speed railway train control, in particular to a method and device for determining parameters for calculating the number of trains controlled by a Radio Blocking Center (RBC). Background technique [0002] When equipped with high-speed railways and passenger dedicated lines of China Train Operation Control System Level 3 (CTCS-3 train control system), the calculation of the number of controlled vehicles is an essential link. [0003] The Radio Blocking Center (RBC) is the core equipment of the CTCS-3 train control system and is a signal control system based on fail-safe computers. RBC generates train traffic authorization (MA) control information according to the ground subsystem or information from external ground systems, such as track occupancy information, interlocking route status, temporary speed limit information, disaster protection and line parameters, and transmits it via GSM-R wireless The...

Problems solved by technology

Therefore, in response to the above problems, relevant technical personnel put forward a local optimization scheme in practical engineering applications. The second paragraph of the "Railway Signal Design Code" (TB 10007-2017) issued by the National Railway Administration in 2017 has a specific requirement for RBC control vehicles. The quantity calculation formula has been optimized systematically, and the optimized formula is used for calculation, but the optimized formula only stipulates the simultaneous utilization coefficient "k" of the track that can store CTCS-3 EMUs within the control range of this RBC "The value is not greater than 1, but there is no clear regulation on how to take the value of "k" in actual engineering applications, which is not convenient for guiding actual engineering applications and is not very practical

[0006] In addition, the number of switching places with adjacent RBCs within the RBC control range in the optimized formula "T RBC-RBC The determination of "is not very accurate. This is because at present, my country's high-speed railway generally adopts the transportation organization mode of automatic block tracking in the forward direction and automatic inter-station block operation in the reverse direction. When the EMU crosses the RBC-RBC boundary, it actually needs to increase The number of vehicles controlled by the RBC is not equal to the number of switching places with adjacent RBCs within the control range of the RBC. The optimized RBC calculation formula may cause a large deviation between the calculation results and the actual application requirements.
