The sections below detail enhancements that will be deployed to aSIST on XXX 2021.
Notification of Weekly Disruption
User Interface Enhancements
Silent Alarm (WIMBLEDON ASC ONLY)
A silent alarm (visual alarm, but not audible) has been introduced at Barnes Junction in the Up direction.
This prevents the audible wrong route alarm sounding when trains are diverted from the Fast Line to the Slow Line in response to line blockages e.g. track patrols.
The visual wrong route alert will display, but no wrong route will be recorded.
Delayed Data Message
The system now checks globally for data updates before displaying the message that no data is being received.
Previously only that singular train describer was checked meaning the message would display frequently in quieter areas
System Back-end Enhancements
Version Control
In the back-end the system will send data (list of trains approaching, routes set etc) every two seconds.
The system will then do a version control check for that data, and auto-reload if the version is old. This ensures all data is up to date.
Route Refresh when Data Out of Sync
The data tolerance has been amended to prevent the TD and s-class (signalling) data becoming out of sync.
Previously, the signalling data could become out of sync, for example a signal placed at danger but the system would not receive this data until 15s later.
