11.1.5 Network Requirements

(a) Datalogger shall be capable of working with different transmission media like
underground telecom cable, microwave (Digital or Analog) & OFC. The modem
can be either in-built or external. The external modem will be housed within the
Datalogger cabinet.

(b) It shall be possible for networking and remote monitoring of several
Dataloggers from the central location. All features like on-line Simulation, Off-
line simulation, failure management, exception logics and Synchronization
should be feasible from the central location.

(c) It shall be feasible to provide IP based networking.

(d) Data storage and management infrastructure: To support the requirements of
local and remote access of online and offline data and alarms and reports – an
approved robust IT infrastructure shall be provided.

(e) Approved system of Data security and safety shall be provided to protect from
viruses and unauthorised access.

(f) Path Redundancy for the networks shall be provided.

Section 2: Applications of Datalogger

11.2.1 Fault & Asset Management
(a) Datalogger system provides data driven decisions to various agencies
involved with asset management and usage. An approved process for
using full potential of Datalogger system by integrating its results with the
existing process shall be provided with appropriate software.

(b) Generation of Exceptional Reports: These reports shall be generated by a
computer connected to Datalogger at the station (and at a central location also
in case of networked Dataloggers). Special software loaded in the computer,
shall implement defined logics and generate exceptional reports as alarms. As
per their category, they shall be sent as messages to required Officials for
prompt action. Please see Annexure: 11-A1 for guidance.

11.2.2 The following users may be provided with exception Reports/Alarms

(a) Maintenance staff of signalling equipments
(b) Electrical maintenance Staff
(c) P - way maintenance Staff
(d) Traffic staff/controllers
(e) Operating staff at station/cabins

Section 3: Remote Diagnostic and Predictive Maintenance
System (RDPMS)

11.3.1 The objective of providing Remote Diagnostic and Preventive Maintenance
system is to assist maintenance team in taking appropriate maintenance
action in advance to prevent the failure of signalling gears.
