Process:
 

•Planning of Train detection system.

Requirements:
 

•Determining the Planning Direction

•Specifying Track Identifiers for Section Tracks

Description:

All topological components of a train path have to be tested for freedom from other rail vehicles. For this purpose, all tracks requiring clearance are divided into track clearance sections. There are different procedures for planning Track clearance sections, which are described in the procedure.

For the creation of cascaded Track clearance sections, please contact ProSig Support.

Attention: Double sensors as part of a level crossing initiation are generated as Sensor.
 

The Track Clearance Section is an Area Object and corresponds to the clearance detection system. The clearance detection system is a technical system that monitors a track section for the absence of rail vehicles. The track clearance section in ProSig comprises the representation of the track section on the topological edge and the logical information for the realization of the technical clearance.

The FMA Component is a Point Object and is positioned at the limits of the track clearance section. Depending on the type of the track clearance section, it can have the following characteristics:
 

•Axle counter  

•Insulated joint

•FTGS-Effect boundaries

The FMA-IO is a Point Object and can be inserted in an FMA Component of the type insulated joint. The FMA-IO can be inserted using the function EPU-Object Inserter. The Process description for this object is found on the page Inserting FMA Feed-Ins and Feed-Outs.

In the PlanPro glossary, the object is formulated as follows:

 
Track Clearance Section (FMA_Anlage)

Technical system that monitors a track section for the absence of rail vehicles; corresponds in normal usage to the track clearance section.

A Track clearance section is used as a stand-alone track path clearance check or for the clearance check of the flank protection section and in evaluation of the sequence of occupancy and being released again to register a journey and thus to resolve sub-track routes. Other switching operations can also be triggered by a track clearance section.

 
FMA Component (FMA_Komponente)

Track clearance section limit (Insulated joint, electrical joint, Axle counter).

The FMA Component is assigned to the point of the track up to which the detection of an assignment is considered secure according to the application guidelines. The Area objects belonging to the corresponding track sections should therefore end exactly at this point object.

To determine the lateral position of an FMA Component, see Modeling Track Clearance.

An FMA component is entitled to limit at least one track clearance section at only one side or at least one track clearance section at each side. In the case of overlapping track clearance section limits (e.g. at the transition from FTGS - to axle count - train detection system), each track clearance section limit should be included separately as an FMA component.

There may be technical facilities for track clearance reporting directly at the height, right and/or left of the track clearance section limit, see also  FMA-IO (FMA_Element).

Traversing an FMA component can also trigger further switching operations, see Switching Device(s) (Schaltmittel_Zuordnung).

Procedure:
 

1.The Planning of the Track Clearance can be carried out with different procedures:
 

oTo Create a Track clearance section and simultaneously define the limits (missing FMA-Components will be created) continue with Step 2.

oFor separate insertion of FMA-Components (and possibly subsequent creation of a track clearance section), see Step 5.

2.When creating the track clearance sections, it is recommended to proceed in ascending chainage. Please note the general description of the Insertion of PSO Area Objects.
 

oThe Insertion of a track clearance section as an axle counter section can be performed with the function 'Axle Counter Section'.

Command Line: PRS_FMA_AZA

Ribbon: ProSig EPU -> Equipment SCT -> Rail Clearance Section -> Axle Counter Section

▪Selecting the limits of the track clearance section is described further in Step 3.
 
 

oThe Insertion of a track clearance section as track circuit can be performed with the function 'Track Circuits'.

Command Line: PRS_FMA_ISO

Ribbon: ProSig EPU -> Equipment SCT -> Rail Clearance Section -> Track Circuits

▪Selecting the limits of the track clearance section is described further in Step 3.
 

3.When inserting, the limits of the track clearance section should be selected. The order of the selection should determine a drivable path (turning allowed).
 

oPossibilities for selecting the Limits:

▪Existing FMA component: If an FMA component already exists at one limit of the track clearance section, this object has to be selected.

▪Existing Signal: An FMA component is generated at the point where the signal is located.
 

▪Existing PZB element: At the point where the PZB element is located, an FMA component is created.

▪Existing Buffer stop or SH2 Signal at the Buffer stop: With a dead-end track, the limit of the track clearance section can be defined by a buffer stop. No FMA component is generated at the point where the buffer stop is located.

▪Point on the topological edge (layer PRS-TOPOLOGICAL EDGE): An FMA component is created at the selected point.

oThe Procedure for inserting FMA Components is described in detail in Step 5.
Editing the Object Attributes of FMA Components is described in detail in Step 7.

oAfter creation, the track clearance section is displayed as an area object on the track layout and stored on the layer PRS-TRACK CLEARANCE SECTION (see illustration above).

4.After inserting the track clearance section, all relevant data should be entered using the function Edit Object(s).

Command Line: OE

Ribbon: ProSig EPU -> Tools -> Edit Object(s)

Illus.: Extract from the Object attributes of the Track clearance section W28

oThe Data input is performed according to the descriptions in the tool tips.

oThe automatic calculation for the attribute 'Local element identifier' (O) is determined
 

▪the smallest switch number of the switches in the Track clearance section or
 

▪the smallest of the track section designations ascending in the Chainage direction, based on the associated object track designation.
 

oFor track clearance sections that are created with a DKW, the attribute 'Local element identifier' should be adjusted manually.

oThe automatic calculation for the attribute 'Code letter' (P) is determined
 

▪'W', if the designation of the Track clearance section (O) is based on a Switch designation.
 

▪'B', if the designation of the Track clearance section (O) is based on a Block line.
 

▪'G', if the designation of the Track clearance section (O) is not based on a Switch designation or Block line designation.
 

▪For Track clearance section on Diamond crossovers, the code letter 'K' should be entered manually.

oThe Attribute 'Track vacancy section component' (Q) contains links to the objects positioned at the limits of the track clearance section (Object type 'FMA component').

oThe Attribute 'Type' (R) determines the type of Clearance detection system and influences the display of the linked Track vacancy section component.

5.FMA components can be inserted either during the creation of a track clearance section or separately. To insert an FMA component separately, execute one of the following functions. The general description of the Insertion of Dot-like PSO should be observed.
 

oThe Insertion of a FMA component of the type Axle counter can be performed with the function 'Axle Counter'. The FMA component is inserted by default as Axle counter.

Command Line: PRS_FMA_AZP

Ribbon: ProSig EPU -> Equipment SCT -> Rail Clearance Section -> Axle Counter

oThe Insertion of a FMA component of the type Insulated joint can be performed with the function 'Insulated Rail Joint'. The FMA component is inserted as insulation joint by default.

Command Line: PRS_FMA_ISOSTOSS

Ribbon: ProSig EPU -> Equipment SCT -> Rail Clearance Section -> Insulated Rail Joint

6.Select a point on the topological edge (layer PRS-TOPOLOGICAL EDGE) or an existing signal or PZB element as the reference point that defines the limit of a track clearance section.

oAfter the creation, the FMA component is displayed according to its type on the track set and stored on the layer PRS-FMA-COMPONENT-<Type>.

7.After inserting the FMA-Component, all relevant data should be entered using the function Edit Object(s).

Command Line: OE

Ribbon: ProSig -> Tools -> Edit Object(s)

Illus.: Object Attributes of the FMA component 60W24/60W28

oThe Attribute 'Track vacancy section limit' 1 to 4 (Z, AA, AB, AC) links the existing track clearance sections, for which the Track vacancy section represents the limit. The linking takes place as described under Editing And Displaying Complex Data - Assigning Objects.

oThe automatic calculation for the designation of the FMA component (U, V, W, X) results from the track clearance sections linked in 'Track vacancy section limit' 1 to 4 (Z, AA, AB, AC). The names of the track clearance sections are concatenated in ascending order in the direction of the chainage, separated by a forward slash '/'.
 

oFor Axle counter that is simply used, the designation suffix (e.g. 'A', 'B') is not calculated automatically. This information should be entered in the attribute 'Designation suffix' (AD). The suffix is then automatically appended to the name of the FMA component (U, V, W, X).

oThe Attributes 'Layout plan name - short' (V) or 'Layout plan name - long' (W) determine the representation of the designation of the FMA component in the drawing in accordance with the settings in the project object, see also Defining Project attributes and Pre-settings.

oThe automatic calculation of the attribute 'Type' (Y) determines the type of FMA component according to the type of Clearance detection system assigned under 'Track vacancy section limit' 1 to 4 (Z, AA, AB, AC).

oFor the Attribute 'Designation Table' (X) the correct designation corresponding to Directive 819.9001 (Planning SCT systems - Symbol designations Signalling plans) is required. If track clearance is planned with insulation joints or FTGS-Effect boundaries, the designation of these components should be the same as for Axle counter.

8.After creating FMA components, missing track clearance sections can be inserted as described in Step 2.
