Problems solved by technology

[0005] This kind of recursive derivation of the "vehicle control code sequence" by manual or computer algorithm for possible low-frequency information codes section by section is very cumbersome to implement, and the derivation is often wrong or incomplete, and the review is also cumbersome.
The compilation of "code sequence table" is very restricted by the experience of engineering designers, and the design risks are difficult to control

Embodiment 1

[0028] This embodiment discloses a method for generating a train control code sequence based on preset train route features, such as figure 1 ,include:

[0029] S100. Using each feature of the train route, preset the train control code sequence template of the route in the database; in this embodiment, abstract the characteristics of each type of route according to various train receiving and dispatching routes.

[0030] Preferably, for the convenience of adaptation, the data types of the abstract route feature are only specified as Boolean type and integer type.

[0031] In this embodiment, the Boolean characteristics of the route at least include: whether the signal for entering the station is closed; whether the signal for entering the station is open for guiding signals; whether the signal for entering the station is open and straight; Is there a train in the departure section ahead?

[0032] Preferably, the Boolean shortcut features also include: "whether at least one g...

Abstract

The invention relates to a train control code sequence generation method based on train route characteristic presetting, which comprises the following steps of: presetting a train control code sequence template of a route in a database by utilizing each characteristic of the train route; obtaining each characteristic value set of the route of the vehicle control code sequence to be generated, querying the characteristic value set in the generated database, and matching to obtain a vehicle control code sequence template with the characteristic value set of the route; and according to the specific access section of the vehicle control code sequence to be generated, replacing the section name in the vehicle control code sequence adapted in the preset code sequence database, and generating thevehicle control code sequence of the access. Compared with an existing traditional design method, the design method adopted by the invention has obvious advantages. According to the method, the corresponding vehicle control code sequence can be inquired and generated from the preset code sequence of the database only by extracting the feature set of the access, operation is visual, the algorithmis simple, item missing is not likely to happen, implementation is easy, and auditing is easy and convenient. Railway signal engineering design efficiency and design quality can be greatly improved, and design risks can be controlled.

Description

technical field [0001] The invention relates to the field of train control code sequence generation in a train operation control system, in particular to a train control code sequence generation method based on preset train route characteristics. Background technique [0002] During the operation of the EMU train, the running path of the train (established by rails and turnouts) is composed of artificially divided into multiple sections of steel rails (separated from each other by insulating joints), and each section of steel rail constitutes (or carries) a track circuit. The track circuit has two main functions: 1. When the train runs to a certain section of rail, the train wheel set short-circuits the track circuit carried by the rail, and the ground train operation control equipment collects and detects that the track circuit is "short-circuited", thereby realizing the location of the train (It can be determined that the train has moved to a certain section of the track c...
