166 KIN LING LEE An Advanced Command, Control And Communication (C3) Solution For Transit Systems

5.2.15 Automatic Train Supervision Function

The Automatic Train Supervision（ATS）Agent provides access to the ATS system. Through
this interface, the ATS functionality is embedded within the C3 system to allow a common HMI
（Human Machine Interface）to be used.

5.2.16 Maintenance Management System Agent
The Maintenance Management System（MMS）Agent is responsible for monitoring the status
of equipment and interfaces, and generating job requests.

5.2.17 Access Management Subsystem Manager
The AMS Manager provides the operator software control and the ability to configure the
system, encode the access smart cards, generate ‘blacklist’, ‘access-list’ as well as the management
of system resources.

5.2.18 Situation Management Subsystem
This subsystem is responsible for the creating and executing pre-defined plans corresponding
to various scenarios in support of operation.

5.2.18.1 Plan Viewer
The Plan Viewer provides the user interface to allow the general system control and
management of incident plans. Plans provide the capability of pre-defining operator responses to
common or expected system occurrences, as well as automating day-to-day tasks.

5.2.18.2 Plan Agent
The Plan Agent is responsible for the control and running of plans. It performs the plans that
are shown in the plan viewer, and is also capable of running plans (manual, semi, fully automated)
in response to certain situations in support of railway operation.

6、OASYS C3 Solution Benefits

The OASYS C3 solution not only departs radically from the traditional ‘silos-type’ approach
taken in the earliest generations of railway control room design, it is also ‘operation-centric’, and
deploys ‘state-of-the-art’ IP technology down to the primary equipment control layer.

We believe this solution offers the following benefits:

˙Better Operation Support
With the integrated concept offered by this solution, cross-functional operation support plans
can be pre-defined and implemented in the system for all likely scenarios, including emergencies.
For example, in the event of multiple terrorist strikes in metro stations, it would have been possible
to manage the situation, through pre-defined plans as it unfolds.
Each of these plans would have pre-determined decision steps to be taken in response to the
real-time events that is occurring. This may include contacting relevant government agencies,
emergency services etc.

˙Uniform Operation User Interface
Unlike older design where different set of hardware and software applications are typically
