DPI Bus Monitor Screen Configuration¶
DPI Bus-monitor supports a range of pre-defined display types depending on size of the screen, screen location and functional needs.
These screens are accessible directly through a URL with following schema: {BaseURL}/app/#display/{type}, eg. http://webserver.local/app/#display/1.
Overview of screen types¶
| Id | Content | Aspect ratio | Optimal screen resolution (width x height) | Vehicle type |
|---|---|---|---|---|
| 1 | Vertical journey, Public Announcement | 32:9 | 1920x540 | Bus |
| 2 | Horizontal journey | 48:9 | 1920x360 | Bus |
| 3 | Vertical journey | 16:9 | 1920x1080, 960x540 | Bus |
| 4 | Vertical journey / Public Announcement | 16:9 | 1920x1080, 960x540 | Bus |
| 5 | Horizontal journey | 32:9 | 1920x540 | Bus |
| t2-left | Horizontal journey | 1920:197 | 1920x197 | Tram (SL18) |
| t2-right | Horizontal journey (reverse) | 1920:197 | 1920x197 | Tram (SL18) |
| t3 | Next stop / destination | 128:9 | 1920x285 | Tram (SL18) |
| b1 | Vertical journey | 16:9 | 1920x1080 | Ferry (Boreal) |
| b2 | Next stop, sensors / Public Announcement | 16:9 | 1920x1080 | Ferry (Boreal) |
| b3 | Next stop, Public Announcement | 9:16 | 1080x1920 | Ferry (Norled) |
* These are approx. values and subject to change.
Distribution channels¶
Additionally, for public announcements, it is possible to target specific screens by which channels they subscribe to. You define which channels to subscribe to in the URL with following schema:
{BaseURL}/app/#display/{type}?channels=channel_name[filter_key}=filter_value,additional_channel_name.
Short platform¶
- t2-left:
{BaseURL}/app/#display/t2-left?channels=short_platform[active_cab]=c1 - t2-right:
{BaseURL}/app/#display/t2-right?channels=short_platform[active_cab]=c1
Keep in mind that the keys and values are case-sensitive.
Supported filters are:
| Key | Possible values |
|---|---|
| active_cab | c1, c2, inactive |
Screen configurations for bus (TaaS vehicles)¶
Screen config 1¶
Running state of config 1, displaying journey (50% of the width) and additional information (fallback, when no public announcements* are showing).
This is the default configuration used for 32:9, and most 32:9 screens should be configured to use this configuration.
Config 1 showing an example of public announcement.
*The public announcements are either html campaigns, texts, video and images.
Screen config 2¶
Running state of config 2. This is the only configuration used for 48:9, and all 48:9 screens must be configured to use this configuration.
Screen config 3¶
Running state of config 3. Intended for screens dedicated to showing journey, i.e. no public announcements will be displayed on this screen.
Screen config 4¶
Running state of config 4. Default state for config 4 is showing journey.
Active public announcements will replace journey.
Screen config 5¶
This configuration is used to display a horizontal view of the line, on a 32:9 display.
Assignment of screen config id for screens¶
General rule of thumb for assignment of configuration id:
- All 32:9 (1920x540) screens should usually be assigned config 1
- All 48:9 (1920x360) screen should always be assigned config 2
- All 16:9 (1920x1080 or 960x540) should always be assigned config 3, if any of these conditions are met:
- This is the only screen on board
- This screen is in front of the bus
- Screen config 4 is used for the right screen when 2x 16:9 screens are horizontally aligned, facing the same way (cf. example 1). (For all other 16:9 screens, use config 3)
- Screen config 5 is used for the 32:9 screens are vertically aligned. (For all other 32:9 screens, use config 1)
Screen configurations for tram (SL18)¶
Screen config t2-left¶
Left side of the tram when active cab is c1.
Running state of t2-left. This is the only state (cf. troubleshooting for this config.
Screen config t2-right¶
Right side of the tram when active cab is c1.
Running state of t2-left. This is the only state (cf. troubleshooting for this config.
Screen config t3¶
State 1 - doors unlocked¶
State 2 - next stop produced¶
State 3 - next stop produced with active stop signal¶
Screen configurations for ferry (Boreal)¶
Screen config b1¶
Running state of config b1. Intended for screens dedicated to showing journey, i.e. public announcements (such as safety instructions etc) are ignored. This should be used for on the left screen in pair with config b2.
Screen config b2¶
Running state of config b1. Intended for screens dedicated to showing journey, i.e. public announcements (such as safety instructions etc) are ignored. This should be used for on the left screen in pair with config b2.
Secondary information, intended for displaying safety announcements, deviations and other media content types. When there is no active media content playing, the screen will show information about next stop, destination and sensor information from the ferry as fallback. The sensor data is derived from following topics:
- telemetry/01001016 - water temperature
- telemetry/01001011 - temperature outside (ambient)
- weather - wind data
Screen config b3¶
Running state of config b3. Intended for screens in portrait mode showing journey on map, public announcements are shown.
