7.5 Autoinformer function
Autoinformer function may be used for automatic (without participation of the driver) public transport stops
announcement with the use of a satellite navigation system.
The main difference from analogous systems is taking into account vehicle movement direction, thereby
excluding false operation at other stops located in the same geographic area.
To use autoinformer:
1.
Attach the speaker to the Terminal (section Connecting autoinformer speaker).
2.
Set the microSD card:
a.
Place sound files in format: wav, 16 kHz, mono, 16 bit to the card root folder. The file name
must not exceed 20 symbols, including the extension, for example, PARKOVIJ.wav. The
record length is recommended within 4 minutes (in case of exceeding, by the following file
reproduction crackle may appear);
b.
Create folders with routes names in the card root folder. The smallest number of routes is 1.
c.
It is necessary to place the BusLine.txt file to the route folders, where response areas and
areas linkage to the sound files are stored.
The format of each zone is the following:
Latitude;
Longitude;
Direction angle α (the angle between the meridian and a vehicle direction);
Spread for the direction angle Δ (see the diagram below);
Outer radius of Rext response zone;
Inner radius of Rint response zone;
Sound file name corresponding to this zone.
It is convenient to fill in the information for zones from the Device tab of the Configurator while going along
the route.
By route forming it is necessary to indicate separate zones for stops in both directions even if the stops are
opposite each other.
