A method for judging fault occupancy of axle counting section

Abstract

The invention provides a method for judging fault occupancy of an axle counting section. The method includes the steps of judging whether a to-be-judged axle counting section is in a non-communicationtrain occupancy state and is an axle counting section where RM train sweeping has already been completed or not, judging whether the to-be-judged axle counting section has adjacent axle counting sections or not, judging whether the adjacent axle counting sections are in an idle state or not, judging whether the adjacent axle counting sections not in the idle state are in an occupancy state or not, judging the running directions of trains in the adjacent axle counting sections are away from the to-be-judged axle counting section or not, judging whether last running trains in the adjacent axlecounting sections are CBTC trains which already pass rear end screening or not, judging the running directions of the trains in the adjacent axle counting sections are close to the to-be-judged axle counting section or not, and judging whether first running trains in the adjacent axle counting sections are CBTC trains which already pass front end screening or not. By means of the method, the stateof the axle counting sections can be converted into fault occupancy from non-communication train occupancy, and the running efficiency of the trains in a CBTC system is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method for judging fault occupancy of an axle counting section. Background technique [0002] CBTC (Communication Based Train Control) system is a safe, highly reliable, and highly stable automatic train control system based on wireless communication. It is currently widely used in urban rail transportation. It is characterized by the use of wireless communication media To realize the two-way communication between the train and the ground equipment, and to replace the traditional track circuit as the medium to realize the train operation control. [0003] In the CBTC system, the ZC (Zone Controller, Zone Controller) system is the core control equipment on the ground, and it is the necessary equipment to realize mobile blocking. The train obtains the real-time position of the train through the speed sensor on the locomotive and the transponder on the line. The transp...

Problems solved by technology

However, under abnormal circumstances, such as when the axle counting head is disturbed or the power supply of the axle counting equipment fails, the axle counting section is actually not occupied by trains, and the axle counting equipment will report that the axle counting section is occupied. In order to ensure safety, the ZC system restricts the rear trains from passing through the track section, and sets the occupancy state of the axle counting section to the non-communication train occupancy state of the axle counting section, which will affect the operation of the train behind the axle counting section and affect the train Operational efficiency, resulting in operational delays
