Domino Type Control cum Indication Panel as per IRS:S-36/87 or RDSO/SPN/186/2004 and its Accessories

  • Introduction
    +

    Operating cum Indication panels (O & I) are critically related to railway signaling system. They are used to reliably display the status of various signaling elements, so that route selection and line clearance operation can be performed without any ambiguity. Domino panels from DES are fabricated out of large number of small sized dominos in matrix formation, each of them being independent module. They offer features of utmost importance for signaling operation as listed below:

    • Quick replacement of faulty components and parts
    • Easy and fast maintenance of panels resulting least shutdown time
    • Compatibility to easily accommodate any kind of remodeling of yards, such as addition, deletion and reconfiguration of signals, points, tracks, axle counters etc.
    • Cost effectiveness without loss of reliability and performance
    • User friendly regarding operation and maintenance
  • Design Features

    Mechanical Structure

    • The body of panel is fabricated from 18/16 SWG cold rolled mild steel sheet as per IS: 513 Grade D and painted with Siemens gray powder coating with texture finish.
    • Panel is provided with detachable back covers that are easily removable to facilitate access to the internal wiring, termination etc and are provided with double locking and sealing facility.
    • Compatibility to easily accommodate any kind of remodeling of yards, such as addition, deletion and reconfiguration of signals, points, tracks, axle counters etc.
    • Side view of Control Panel (with provision of Leg space for the operator & faceplate inclination angle of 30o) & Side view of Control Panel (without provision of Leg space for the operator & faceplate inclination angle of 60o)

  • Faceplate
    +
    • The illuminated faceplate is kept at an angle between 30° to 60° or 90o from horizontal plane for proper visibility and convenient operation.
    • The yard layout is reproduced on the faceplate of the panel in accordance to its geographical position. The detailed yard layout showing tracks, points, signals, level crossing gates, sand humps, platforms, stationmaster’s cabin etc. is printed on to the panel faceplate. The track occupancy and route status, point status, main and shunt signal status etc. are represented by an illuminated diagram.
    • The areas covered by each track circuit are clearly distinguished by separate colours. Width of track layout is 7mm(+1mm), for proper visibility, even in poor ambient light. Minimum length of any track is generally kept not be less than is 1or 2 domino modules.
    • Push Buttons for operating of points, signals and controls etc., are normally provided on the illuminated diagram itself in Geographical order.
    • Group buttons, emergency buttons, emergency counters, SM’s key are also provided on the faceplate, for convenient operation.
    • Indications on the panel are provided through clear (colourless) white/ red/ yellow/ green light emitting diodes (LED’s) from international manufacturers like Agilent, QTC or Everlight.
    • Faceplate is covered by transparent acrylic sheet of 4mm thickness + 0.5mm which is fixed on the top of the faceplate by a removable frame of minimum 2 mm thickness + 0.2mm.

  • Domino Module
    +

    A domino is a mini sized independent module having separate power supply and inputs. Its main building block is rectangular and is made of moulded Nylon having a honeycomb inner structure divided into a number of run-through chambers for holding the panel elements like LED’s, switches etc. and there connecting leads which ensures low loss electrical path.

    Each domino has its own panel of duly matched size and it is clip fitted at the front of the nylon block. The PCB for the module is fitted at the back plane of the same block. The multi pin connector of PCB is soldered to the members of the respective wire groups whose other ends are crimped to rigidly fitted terminals or connectors already wired to relay racks.

    A domino consists of easy to dismantle parts like nylon block and the PCB with connector and a domino module itself is easily detachable from the panel built out of arrays of dominos, without disturbing the neighboring members.
