1 IntroductionAs part of a Microlok interlocking maintenance diagnostic and data replay facilities shall be provided. Remote access to these systems is also required by the local Maintainer from their site office. This document covers the technical requirements of the Maintenance System including system Architecture, Operation, Interfaces, Testing Support and Training.

The area to be covered by any particular facility will be detailed in the Signalling Functional Specification.

The combined Diagnostic/Logger/Replay system is hereafter referred to as the Maintenance System.

2 System Architecture

2.1 General DescriptionThe Maintenance System shall comprise of the following components, which shall operate in an integrated environment to provide the required level of functionality.

• 1 x Logger/replay/diagnostic/rack mounted computer units • 1 x 22” LCD screen • 1 Keyboard and Mouse • 1 x Printer

Larger interlockings may require a larger screen to avoid scrolling vertically as well as horizontally.

Where the interlocking and data links are duplicated, a separate system shall be provided for each side.

An additional system shall be provided in the Maintainer’s depot for each interlocking.

The Maintenance systems will communicate to the Microlok Interlocking via RS232 serial interface for signalling data and record the information based on events stored in text files on the local hard drive. The maintenance system will then display the indications in the form of a detailed map on the LCD screens.

The dual redundant pair allows for one workstation to replay historical data while the other workstation continues to log and display indications in real-time.

For diagnostic type information the maintenance system will connect to the Microlok diagnostic ports. This can be either.

1. For serial links, a network of fibre optic modem sets or diversity link controls that can connect the RS232 links directly, or

2. By Ethernet where the Microlok diagnostic ports are connected directly to Ethernet switches.

To facilitate remote access facilities, the maintenance systems at the interlockings will be connected to a dedicated private network to the system at the Maintainer’s depot. W

2.2 The Workstation

2.2.1 Logger/Reply Workstations Two rack-mount Maintenance Workstations shall be provided for a duplicated interlocking. They shall be located in a 19” cubicle and each workstation will be provided with a 22” LCD monitor. Each workstation will be provided with its own keyboard and mouse. All workstations shall have the facility to burn CDs/DVDs and will be connected to the dedicated private network for remote access of data.

The two screens may be connected to both workstations to provide a larger viewing area. In this case, the screens can select the workstation video input required.

2.2.2 Diagnostic Access Access to Diagnostic Microlok ports using Microlok Tools software shall be by the same maintenance workstation. Windows will be used where viewing of both functions if needed simultaneously.

2.2.3 Remote WorkstationOne Remote workstation shall be provided at the Maintainers depot. It will consist of one rack mounted workstation, one 22” LCD monitor with keyboard and mouse. This workstation will be connected to the private network so that it will be able to remotely interrogate the Diagnostic and Replay/Logging functions of the maintenance computers that will be installed in the interlockings. Other equipment may also be located in this equipment rack.

2.3 User Interface The User Interface is based on industry standard practice using a graphical computer display and keyboard and mouse user input. In case of mouse failure, the alt keys can be used.

2.4 Printers A printer shall be provided for each workstation.

2.5 Workstation Desk Layout Each maintenance system’s VDU, keyboard, mouse and printer shall be located on an arrangement. The desk will also be required for managing signalling documentation and shall contain at least one drawer.

2.6 System Security Security measures shall prevent users from accessing system functions, utilities and facilities not included within the default authorities for their logon classification type.

2.6.1 Microsoft Windows Security Local Administrators shall have the facility to manage Microsoft Windows logon passwords and change user access rights.

The system administrator shall be able to:

or re

fere

nce

only



• Add, change and delete user accounts, authority levels and passwords of all Microsoft Windows users.

• Able to set screen display defaults and to modify screen display formats, layouts and appearances of the system.

Once a user’s workstation has ‘booted up’ and logged on to the Windows network as a valid user, the MISS application shall automatically load and display the various displays. The Microlok Interlocking System Simulator (MISS) application shall display:

• The track plan • The state of indications received from the interlocking (e.g. track occupancy,

approach locking where available, signal status, train stop status etc). • Alarms

2.7 Data Flow Considerations Consideration shall be given to the design of the data flows for use in both the MISS testing system and the final configuration with the replay.

The MISS operation, the operation at certain inputs (such as tracks and point detection) will be switched by the MISS screen. Other inputs such as signal repeaters and point detection will be turned around from that location’s outputs.

To fulfil the dual purpose, the indications displayed on the track panel shall be from the interlocking Genisys connection (and not as a direct indication at switch position).

Thus to drop a track circuit the data flow in the MISS shall be:

• Trackside screen – drop track by switch • Drops MK2 field I/O input • Interlocking input drops • Control system bit lost • Genisys replay link loses bit • Trackside screen displays track down.

Functions used in the MISS but not required for the replay shall be blank or non- functional on the Replay screen.

Where certain bits are displayed for testing purposes they may be retained in the replay provided the relevant indication bits are sent from the interlocking into the control system link which is also ported to the replay.

Where a Genisys Server is provided to manage the control system to interlocking communications gateway, other indications may also enter at this point (such as from an adjacent automatic section, or higher aspect or power supply alarms) for direct display on the replay situation.

3 Operation Description

3.1 Logger/Replay Workstations

3.1.1 Logger The Maintainer will have access to retrieve Log files from the home directory C:\MISS\. A separate log file is created each day. These files will be accessible to copy via the private network.

With

n - f

or re

fere

nce

only


The log files contain the variable name, the state of the variable and time stamp. The data will be stored in real-time. The time stamp will be based on the Logger workstation time, with the time on both workstations synchronised to a common clock.

The system shall be capable of storing/maintaining at least 6 weeks of retrievable logged data.

3.1.2 Replay The maintenance system shall include a Replay facility on the Logger/Replay Workstation. The replay facility shall playback the interlocking operations based on a particular log file.

To enter replay mode, the Maintainer will be required to start up a replay session and select the date/time required to replay. When a replay session is running, the alternate maintenance system shall remain logging.

The active logs files can be copied manually to a second or remote workstation for playback.

3.1.2.1 The Replay InterfaceThe replay interface will provide the following functionality through the toolbar buttons:

• Eject • Stop • Pause • Play Forward • Play Reverse • Fast Forward (at speeds of typically 2x, 3x, 4x, 5x, 10x, 20x, 30x etc) • Fast Reverse (at speeds of typically 2x, 3x, 4x, 5x, 10x, 20x, 30x etc)

3.1.3 Indications Indications on the MISS can either be dynamic or static. Dynamic indications change the way they are displayed based on their signalling status according to the information received by the Microlok, Static elements will not change.

For a detailed description of the indications refer to the following sections:
