A state detection method for MATC city track turnout section

Abstract

The invention discloses a state detection method of a switch section of an urban rail adopting maglev automatic train control (MATC). The state detection method comprises two steps of switch section acquisition and processing and train tracking processing. Due to a track switch beam of the urban rail adopting MATC is not provided with an axle-counting magnet head, track switches of track crossovers are not all positioned, and the problem that normal unlocking by three-point check cannot be met. In the switch section acquisition and processing step, combination processing is carried out on theswitch sections of the track crossovers, when the track switches in the track crossovers are not all positioned, the states of the switch sections in the track crossovers are enabled to be consistent;and in the train tracking processing step, if the track switches in the track crossovers are in the reverse position, the switch sections in the track crossovers are combined into one section, by looking for rear sections and front sections of the section, so that three-point check conditions are met to solve the problem that an approach road section at which the track switches are arranged in the reverse position cannot be unlocked normally, and it is ensured that trains safely and orderly pass through the track switches.

Description

technical field [0001] The invention belongs to the field of safety driving system of MATC-standard city track turnout section, and in particular relates to a state detection method of MATC turnout section. Background technique [0002] In order to ensure the safe operation of urban rail trains in the turnout section, the unlocking of the computer interlocking section (not the first section) is carried out in a three-point inspection method: relying on sensors such as axle counting heads and track relays (GJ), Detect the occupancy and clearance of this section and the front and rear sections, and combine the interlocking relationship. When it is determined that the train occupies this section, clears the rear section, occupies the front section and clears this section, the approach is normally unlocked , otherwise it will not be able to unlock normally. In this way, the train can pass through the turnout safely and orderly. [0003] However, due to the special engineering ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is: the present invention provides a kind of MATC standard urban track turnout section state detection method, when the turnout in the crossover line is not all positioned, the turnout section of the crossover line is combined to process, so that each turnout section in the crossover line The state is consistent; when the turnout in the crossover line is in the reverse position, combine the turnout sections in the crossover line into one section, and find the rear section and front section, so as to meet the three-point inspection conditions and solve the problem of arranging the turnout reverse position The problem that the route section cannot be unlocked normally
