ISO 9001: 2008 Effective from 18.06.2012 RDSO/SPN/196/2012 Version 3.1.1
Document Title : Specification of Train Collision Avoidance System
5.19 Health Check
5.19.1 Loco unit shall continuously check its health status including its
communication with other Loco / Station unit. If the health status is not found
OK, the same shall be displayed on Loco unit LP-OCIP & Loco unit shall
switch to Failure Mode.
5.19.2 Loco unit units while in communication with station shall upload its health
status& Brake Interface unit (BIU) isolation status to station unit. The station
unit units shall transfer the information so received from Loco unit units &its
own event log to a Centralized Management System on real time basis. The
Centralized Management System shall have suitable management software
for diagnostics, maintenance & analysis purpose.
5.19.3 Loco unit shall also transmit its health & BIU isolation information to
Centralized Management System through its GSM.
5.19.4 If Loco unit, even in unhealthy condition, is able to communicate with station
unit, this information shall be communicated to station unit, which then will be
transmitted to the Centralized Management System located in the control
room. Loco unit shall also transmit this information to Centralized
Management System through its GSM.
5.20 Interoperability: The Loco unit of a manufacturer shall be interoperable with
Station unit& track-side equipments of another manufacturer & vice versa.
5.21 Direction detection in tunnels: Duplicated RFID tags at suitable interval shall
be provided on track in tunnels to detect the traffic direction of the train.
5.22 All the messages displayed on LP’s and SM’s OCIP shall be got approved from
RDSO & shall be logged in respective data logger alongwith date, time & other
relevant information.
5.23 The Loco unit shall have capability to be interfaced with two OCIPs, if required,
in locomotives having two driving cabs or two driving positions in the same cab.
In such cases, except the SOS buttons all other functionality of other OCIP i.e.,
of non-driving cab/ position shall get disabled automatically.
5.24 Loco unit, Station unit& Centralized server shall also have GSM interface for
transfer of log & other events to Centralized Management System directly in
addition to other communication link between Loco & Station unit and between
Station unit& Central Server.
5.25 In case of more than one situations/ scenarios existing at the same time, the
Loco unit shall take action as per the most restrictive situation/ scenario.The
Loco unit shall make speed profile/ brake curve for different situations based on
movement authority, speed restriction and other information as received from
Stationary unit or Loco unit. Loco unit shall take action as per the most
restricted speed profile/ brake curve at any point of time.
5.26 Wherever Station unit is referred, it shall also mean Station or IBS or Gate unit.
5.27 Once a situation is detected by Loco unit based on the information received by
it, which warrants application of brake & further update of information is not
available, the action for brake application shall be initiated or continued if
already initiated as per the brake curve at the time receipt of last information.
Further update of brake curve shall be done only after start of receipt of further
information.
