DKS - Railway communication system in GSM band

Description

DKS system covers completely connection between mobile means and infrastructure represented by dispatcher position. System uses network of GSM operators and sufficient coverage of the GSM signal is requested. System ensures duplex voice connection of the subscribers and also addressed data transmission among subscribers. System involves localization of the mobile means through GPS navigation. System is designed primarily as railway radiocommunication system but alternative disposal out of railway segment networks is possible.

Data transmission on mobile means uses GPRS connection. Dispatcher position connected to application server could use GPRS technology or hard wire IP connection.

Features in railway communication system modification

• Network configuration that ensures both dispatcher console and station guard console function on one rail route.
• Identification of rail vehicles as per train number.
• Voice connection between dispatcher or guard and train on the railroad.
• Voice connection of other participants of the railway operation.
• Transmission of the commands and reports to/from trains.
• Selective and general STOP from dispatcher or station guard position.
• Recording of the communication and system operation on selected recording device.
• Continual monitoring of the running trains on the railroad via GPS.
• Monitoring of occupancy of the rail route with relation to the area responsibility of particular dispatchers or station guards on the whole railroad.
• One-button call to station guard performed by automatic redirection of the running train to relevant station guard as per position evaluated from GPS data.
• Sharing of operation data among infrastructure subscribers via LAN connectivity.
• Data transmission of external applications from trains to railway infrastructure.
• Increase of operation safety especially in case of operation on the railroad of lower category.
• Simple and economic advantageous modification of the system on other railroad.
