Announcement railway station in the train

Details: Announcement railway station in the train

System Announcements railway stations based on satellite positioning system, was developed and tested to standards UIC 568 and EN 50155 in Elektrokem.
Using an automatic station announcements can be achieved by good intelligibility, because the message used a studio recorded words stored in computer memory from which the message goes, and it avoids the possibility of delays or failure to notice the wrong station and also the person responsible for an announcement released from his demanding job.

The system of automatic station announcements on the train contains the following components:

Ethernet network 100 MBs
embedded computer with a graphical interface
- core CPU Intel PIII 1GHz
- 256MB RAM
- VGA 640x480 true color
- Windows XP Embedded
- DotNet 2.0
- LAN Ethernet RJ45 100 MBs
GPS receiver
GPRS receiver / transmitter
I / O logic to determine the active cab
sound system connected to an Ethernet network
LED displays associated with the RS485 bus
ethernet adapter to connect to RS485 bus

After entering the number of the train with a host computer, the system performs verification of the correctness of the data that exists in the database list of stations associated with the number of the train. If the data on the number of train properly, the system begins to load data from database.

After what ends up connecting to the server, the program determines the current position of the train and by comparing previously created a linked list and the current position of the train, the program detects the railway station according to which it moves. After that, the graphic presentation appears on the LCD screen.

During the train ride, the graphic presentation continuously move data up and highlight the upcoming station. The computer system, according to the criteria set time continuously sends information about its position toward the center to manage traffic through GPRS / UMTS server set to the disposition of the train connected to an Ethernet network of railways. After determining the current distance of the GPS receiver (train) from the requested point (station), it is possible to set specific conditions to the software which will be carried out functions of travel information. One of the conditions of the current minimum distance from the train station, which begins with giving voice and visual travel information on upcoming stations, arrival time, calculate the time deviation from the schedule according to satellite time.

With the arrival of the train at the destination (train station) the system automatically ends with the work and goes into standby mode to enter the new number of trains or shutdown if the control room is shutdown.
Database of stations makes the program structure known as a linked list.

For voice information using the words recorded and processed in the audio studio. Program of the word into oncoming station connects to one or more sentences that are using the audio card sent to your computer sound system.

Visual information is given through the computer and info display, which is connected to the system via the RS485 bus, in the form of text print called station.
