Document Title: SPECIFICATION FOR FOG PILOT ASSISTANCE SYSTEM for SAFETY (FOG PASS)

Printed:

Prepared By: SE/Signal Checked By: ADE/Signal-V Issued By: Director/Signal-III of 11

2.0 Purpose : This document sets forth general, operational, technical and performance

requirements for Fog Pilot Assistance System for safety ( FOG PASS). 3.0 Scope of Application :

1.1 FOG PASS is a non‐vital and non‐signal system. Aim of this system is to assist the Loco pilot by giving pre‐warning about the approaching Landmarks such as Signal, LC gate, PSR etc. where the Loco Pilot’s attention is required. This device is without any SIL level hence has chances of malfunctioning in case of system troubles as well as in case no GPS signal is received, it is an indicative device and shall not be relied upon fully for signalling information[HP1].

1.2 Route survey for collecting the GPS co‐ordinates of landmarks is not covered. It

will have to be carried out separately & programmed into FOG PASS.

4.0 Details: 4.1 Terminology

4.1.1 Landmark: A fixed location such as Signal, level crossing gates, Permanent speed restrictions, neutral section or any other location as identified by the user as landmark.

4.1.2 Pre‐warning distance: It is the distance from a landmark from where the warning shall be given while approaching that landmark.

4.1.3 Short Description of Landmark: It is the text to be displayed on LCD panel to indicate about the approaching landmark. This may consist of Station code/ LC gate No., its description in short, location etc.

4.2 General Requirements

4.2.1 FOG PASS shall be universally suitable for all types of sections of Indian Railways like single line, double line, twin single line, multiple lines etc.

4.2.2 FOG PASS shall be suitable for all types of electric and diesel locomotives, EMUs/ MEMUs/ DEMUs and any other self propelled vehicle treated as train.

4.2.3 FOG PASS shall be capable of working in all types of electrified as well as non electrified territories.

4.2.4 FOG PASS shall be suitable for train speeds up to 160 KMPH.

4.2.5 Each FOG PASS unit shall store events essential for diagnostic purpose for a period of 15 days.

4.2.6 It shall have built‐in re‐chargeable battery back‐up for 18[RB2] hrs. duration when fully charged.

4.2.6 FOG PASS unit shall be designed as a Loco Pilot’s tool and thus it shall be portable, compact in size, light & of robust design. The weight of the unit, including battery, shall not be more than 1.5 Kg, this shouldall not include battery charger, shoulder bag and swiveling arrangement[HP3]. It shall be a portable unit which can be easily[RB4] carried by the driver for placement on the cab desk. [RB5]



Printed:


4.2.7 Each FOG PASS unit shall be supplied with a suitable shoulder bag of nylon material for porting & carrying. The design of the bag shall be such that for using the unit only the upper portion of the bag is required to be opened & there is no need to take the unit out.

4.3 Functional Requirements

4.3.1 Location identification & Route Log

4.3.1.1 FOG PASS shall be an intelligent system having GPS receiver with small antenna, which shall detect location of the locomotive when kept in the locomotive and shall continuously calculate the distance remaining to the next landmark(s) already loaded in the system by the purchaser.

4.3.1.2 The unit shall be capable of detecting its location correctly + 10 meter [RB6]if switched on anywhere on the track for which the route data is already programmed in the unit and after movement, it correctly displays the approaching landmark.

4.3.1.3 FOG PASS shall be programmable to feed the GPS co‐ordinates of all Landmarks as identified by the user along with their short description & location. The GPS co‐ordinates shall be collected by carrying out route survey of the section separately.

4.3.1.4 The FOG PASS unit shall be capable of storing multiple route data in its memory. The system software shall enable the driver to easily select among the loaded routes using the key pad.

4.4 Pre‐Warning, Display & Announcement:

4.4.1 The System should give warnings as per following scheme:

Approaching Landmark Type

Audio Warning Visual Indication Pre Warning Distance

Neutral section Announcement of voice in Speaker

Suitable text on LCD display with blinking backlight.

250 M[RB9]

Any other Landmark As defined by the purchaser. The landmark types & pre‐warning distances given above are only for guidance and can be changed by the user depending upon local site conditions.

4.4.2 Once the FOG PASS unit is within pre‐warning distance, as prescribed in Clause 5.2.1[RB10], of the approaching landmark, it shall display the short description & the remaining distance (in Meters) of the approaching landmark on first (top) two[HP11] lines of LCD in large fonts till the landmark is passed.
