Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] At the same time, in order to more accurately describe the position of the train on the line, on the basis of the original physical section, the physical section is further divided into several logical sections according to certain principles, and the logical section is used as the smallest division unit of the track. The description of the track circuit is realized based on interconnected logical sections. The division principle of the logical section is to divide the physical section as accurately as possible under the premise of ensuring that no section jump occurs during the train running.

[0036] In the CBTC system, when performing logic calculation and track...

Abstract

The invention discloses an orbital tracking method. The method comprises: searching, in an electronic map, a position of a physical section to be checked in an orbit line and the physical section round the physical section to be checked; determining whether the physical section to be checked and the physical section around the physical section to be checked are in an occupancy state or an idle state; if the sections are in the idle state, directly sending the state of the physical section to be checked to interlocking equipment; if the sections are in the occupancy state, further determining whether a logic section within the physical section to be checked and a logic section within the physical section around the physical section to be checked are in the occupancy state or the idle state; if the sections are in the idle state, directly guiding an automatic protecting system ATP of a ground train to a safe side, and warning in a downtime way that a logic error exists. The method avoids that the ground ATP system directly is directly guided to the safe side due to the logic error, and avoids a situation that affects the operation safety of the system like losing the car in a complex circumstance.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail tracking method. Background technique [0002] The automatic control technology of rail transit trains plays an increasingly important role in the command of trains and the safe and efficient operation of trains. For the automatic control system of rail transit trains, train positioning and track state monitoring are the basis of control. Among them, train positioning is the key technology of rail transit train automatic protection system. It is the basis for implementing automatic train control, realizing traffic command automation and train operation automation. It directly involves traffic safety and train operation efficiency. Once there is a problem with train positioning, it will cause accidents. , causing damage to personal property. The traditional signal system closely relies on the trackside equipment to locate the train position in the physical sect...
