Technical Supervision Tool (TKSUP)

aids the technical operator to control and monitor the multi-node architecture by providing a real-time, graphical presentation of the status of the various nodes, together with the state of the dual node redundant partner for server nodes. The ability to instantly flag system errors and non-operational conditions greatly aids the maintainer’s response time to any system errors

TKSUP employs a UBSS process called___ , which acts as an agent collecting system state information required for the monitoring. The agent broadcasts these collected system states to TKSUP for graphical display

ISUP

____ has been implemented to monitor multiple TopSky - ATC

partitions from a central monitoring station. The main objective is to

provide the user a comprehensive monitoring and controlling

functionality for multiple partitions on a graphic user interface.

CTKSUP

The principal functions of TKSUP are:

1. Application Control and Monitoring

2. System and Memory monitoring

3. Integrated Graphical Recorded Data Archiving Tools

4. Network Monitoring

5. System Data Set Handling

CTKSUP

is designed to monitor multiple sites by providing

a top level view of each site. Each site is represented as a color-coded

button

The _____ is designed to alert the maintainer to any remote problems by allowing him to drill further in to the site. On clicking the relevant site button a TKSUP instance is launched for the site displaying the usual node device and dual node states

color-coding scheme

To overcome the issue of attempting to control the same system resources from more than one position, the concept of ____ is used. By default each TKSUP position is able to listen and display all monitoring information, however if the user wishes TKSUP will make sure that this instance has a control

exclusivity

Token before allowing the user to control the system. The principal

functions of CTKSUP are

Partition status monitoring

Activity Logs on Hard Disk

Events Printing

The CTKSUP Main window Drop-down menu bar is composed of the following buttons and sub-menus:

File

Printer

Help

UTC date and time

Between the Drop-down menu bar and the Partition Monitoring area, the UTC date and time from the local node are displayed. The UTC date and time are updated every second

Partition Monitoring Area

The CTKSUP Partition Monitoring area is composed of as many buttons as there are partitions in the monitored system

Partition status color coding scheme

1. White

2. Green

3. Red

4. Yellow

5. Cyan

At the Messages window; Messages are also stored offline for___ in the run directory

7 days

Toolbar

At the bottom of the main window, the toolbar displays the following

buttons:

The TKSUP Main window is composed of the following items

1. The Drop-down Menu bar

2. TKSUP Status

3. The Node Monitoring area

4. The Time and Date

5. The Messages window

6. The Toolbar

The TKSUP Main window Drop-down menu bar is composed of the following buttons and sub-menus

1. File

2. Monitor

3. Control

4. System

ACCESS

This shows the current access level of the TKSUP – this will be eitherMonitor or Control

Access: Monitor

full access to all information on the TKSUP, but no permission to modify any node or device (ie cannot START or STOP a node)

Access: Control

Full access to all information on the TKSUP as well as the ability to modify any node or device state. Note that to modify anything on the partition, CONTROL access and a LOCAL TOKEN state will be required

CLOCK

Show the state of the connection to the GPS clock. This

CLOCK staate

BLUE - the current state is unknown (TKSUP startup state)

GREEN - the system is time synchronized and connected to an external time source

ORANGE – the system is time synchronized but there is no external time source or the external time source has failed

RED - the system is not time synchronized, external time source may or may not be available

ISUP State

GREEN – connected to ISUP

YELLOW – connected to ISUP, but no message received from ISUP in more than 10 seconds

RED – no message received from ISUP for more than 15 seconds

Token state

QUERYING – This TKSUP is looking to other instances of TKSUP for current TOKEN owner (TKSUP startup state).

REMOTE – TOKEN control is currently being held by another TKSUP instance

REQUESTING – request TKSUP TOKEN from another TKSUP instance

LOCAL – current TKSUP holds TOKEN control

The TKSUP Node Monitoring area is composed of as many items as there are nodes in the monitored partition. Each item has the following information:

1. Color-coded status icon

2. Devices access button

3. Node name

4. Node UBSS status

5. Node DNC status

Node Status Color Coding Scheme

One of the decisive features of the Supervision Tool’s GUI involves the color scheme used in the presentation of the status of nodes. These colors enable the maintainer to instantly recognize the status of a particular node

Node Status Color Coding Scheme

Offline - white

Online - green

Online - yellow

Starting - yellow

Shutdown - orange

Resident only - purple

Exited - red

Unknown - cyan

Suspended - grey

Monitoring the devices status display

Color-coded status icon

Device name

Device status

Device status color coding scheme

are displayed along with a colored icon for an instant identification of the current status. The following table sets out the colors used and their representations

Device status color coding scheme color

Ok - green

Operational - green

Starting - yellow

Not ok - Orange

Failed - Red

Detached - purple

Standby - brown

Unknown - cyan

Surveillance Remote Control and Monitoring System (RCMS)

is to ensure the safe and reliable operation of the Air Traffic Control Systems such as: Primary and secondary radars, Center Systems, Ancillaries equipment

Indicator bar

displays information about the Alerts page buffer content of all remote RCMS stations, the connection and the control status of the selected station. The selected station is related to the active synoptic window

Remote Control Electronic Unit (REU)

Serves as a communication interface between the connected equipment and the public switched network.

Remote Control and Monitoring System (RCMS)

Designed for maintenance purposes to be able to access all the navigation systems and it enables all the signal parameters to be set and read

Control Tower Unit (CTU)

Provides system “main status” and allows to switch the ILS to the active runway
