FOREWORD

Introduction of modern technology in locomotive cabs has also increased the requirement of different and increasing number of HMI (Human-Machine Interface) systems for providing control and feedback functionality. This causes two types of problems; one there is limited real estate inside a locomotive cab and it is not possible to provide space for mounting such large number of HMI, two the equipment is usually sourced from different manufacturers and as such each HMI is different which is likely to confuse the operator.

DIALS is equipment designed for combining all HMI requirements for locomotive cabs and presenting it to the locomotive operator in an ergonomic manner with prioritization such that the operator can concentrate on the task on hand.

In future DIALS equipment is expected to replace all locomotive gauges and indicators thereby substantially reducing the cabling / piping requirement for the operators desk and thereby the associated costs.

3. Each row entry shall be time stamped and the date time data shall be obtained from the local RTC.

4. It shall be possible to view this log file on the DIALS display. This file shall be accessible in read only mode when it is viewed on the system.

5. It shall also be possible to download and view this file offline.

6. Data shall be stored in XML format. The DIALS manufacturer shall propose the data dictionary and XML file structure for approval by RDSO.

6.10 Multiple display per loco cab and automatic failover The system shall have feature of supporting multiple displays per loco cab. The following table details the recommended configuration of displays for different types of locomotive / DEMU cab.

S. No. Locomotive Cab Type Recommended Display Configuration 1. Single cab with two

control stands for bi-directional operations

Two DIALS display units per control stand. (Total of 4 display units per locomotive) These four displays units shall be assigned a priority number as given below: 0: Primary display on operative control stand (fully featured). 1: Secondary display on operative control stand (basic display). 2: Primary display on the non-operative control stand (fully featured) 3: Secondary display on the non-operative control stand (basic display).

2. Dual cab locomotive Two DIALS display on the operators control console. One DIALS display unit on the assistant’s desk. (Total of 3 display units per cab, 6 per locomotive) These 3 displays units shall be assigned a priority number as given below (referenced to working cab): 0: Primary display on control console (fully featured). 1: Secondary display on control console (basic display). 2: Display on the assistant’s desk (fully featured).

3. Diesel Electric Multiple Units

Two DIALS display on the operators control console. One DIALS display unit on the guard’s desk. (Total of 2 display units per cab). These displays shall be set up such that one display on the control console shall always display the Driving Display Screen. The other screen can be set up to display any other information as required by the locomotive operator. These 2 displays units shall be assigned a priority number as given below: 0: Primary display on control console. (fully featured) 1: Secondary display on control console (basic display).

Note: Use of multiple DIALS equipment per locomotive shall necessarily require Ethernet switch suitable for IEEE 802.3 10baseT 100baseTx M12 D-Coding. Such a switch is also required for DPCS. Therefore care should be taken while ordering equipment for locomotives equipped with DIALS and DPCS.

These displays shall be set up such that the display with the highest priority (lowest priority number) shall automatically revert to display the Driving Display Screen whenever the vehicle is in motion (speed >0 kmph).




Page 18 of 22

Incase the operator commands a display mode other than the driving display on the highest priority display, this shall be provided when the speed zero (speed = 0 kmph) and the screen shall revert back to displaying the operating display when the locomotive moves.

The other units can be set up to display any other information as required by the locomotive operator.

Incase of failure / power-off of display unit, the lower priority display units shall be promoted in the priority listing such that the highest priority display again displays the Driving Display Screen when the vehicle is in motion.

6.11 Health monitoring and failsafe functioning of equipment DIALS is the primary information resource for the locomotive operator and hence is critical to the safety of operations. The equipment shall have fail-safe features that shall automatically detect equipment errors and alert the operator.

For locomotives equipped with multiple DIALS each shall monitor other DIALS over the Ethernet and alert operator of errors.
