Halogen Browser

The Halogen Browser is a software tool which enables the user to view a graphical representation of the information held in the Halogen database. The information displayed is based on events, which correspond to individual logs from Halogen. These events combine to form a "picture" of the network of roads that are of interest.

The information displayed is retrieved from the Halogen database by first indicating what data you are interested in seeing, then asking the Halogen Browser to provide you with that data. It is possible to submit requests for 4 forms of data:

Range	A range query allows the user to specify a start and end date/time, all events in this range are then retrieved. With range data, it is possible to step through range data, and also to have the Browser automatically "replay" the events in sequence.
Snapshot	A snapshot query retrieves the state of devices at a given point in time.
Current Values	The current values query retrieves a single snapshot of the most recent state of devices.
Up to date	The up to date option will retrieve a snapshot of the most recent state of devices, and keep this data up to date in real-time.

The Browser displays a map, on which it is possible to view the following types of events:

• Sign Settings
• Signal Settings
• Logging System Status
• Faults (both Equipment Faults and Telephone Faults)

Three zoom levels are used to show the events at different levels of detail. Scroll bars and "click and follow" allow navigation around the map. An additional "overview" map shows the position of the displayed information relative to the map.
