Inteletrack's product range consists of portable end-of-train (EOT) devices. The fixed end-of-train-telemetry (EOTT) consists of a cab display unit (CDU) and sense and brake unit (SBU), both fitted with GPS. Wireless derailment detectors can detect dragging equipment. A reliable, low-cost, track warrant satellite signalling system is also included.
Portable, end-of-train braking monitor devices
The telemeter is a portable end-of-train device that monitors the braking system of freight trains. Emergency brakes from the rear of the train can be activated from the cab unit. The system can be integrated with wireless derailment detectors mounted on the track.
The fixed EOTT consists of a CDU that displays the information to the train driver, and an SBU that is mounted on the last wagon of the train. Both the CDU and SBU are fitted with GPS receivers.
The system has the following features:
- Pressure display
- Train integrity
- Speed of locomotive and last wagon
- Length and change in length of train
- Automatic block clearance
- Tracking of SBU via GSM network
- Logging in SBU and CDU
- Emergency brakes
- Service brakes from last wagon
- Air generator
Dragging equipment detector (DED)
Our DED is a very easy to install unit that fastens with four bolts to the bottom of the track. It is therefore easy to remove when standard track maintenance is performed. Our DEDs can be configured to be wired into existing cables or can be equipped with a radio transmitter that will deliver any alarms regarding any dragging equipment or derailed wheels on the train directly to the driver via the telemeter display. The radio transmitter comes with vandal-proof batteries with a guaranteed lifespan of ten years.
Cost-effective safe signalling is a major challenge in Africa. By installing a satellite signalling system, not only were the major aims achieved, but also additional benefits like real-time tracking of trains, additional security and low maintenance costs.
Locomotive satellite unit
The satellite units communicate directly to the satellite every ten minutes, reporting the GPS' position, direction and speed. A keypad / display allows for SMS messages to be send from the locomotive or received from the dispatcher.
Digital input reports the following statuses:
- Locomotive switch on
- Emergency request
- Station clear
- Section clear
A geo-fence can be set up to warn the dispatcher when the train nears the end of a valid warrant.
Dispatcher base station
The base station consists of four standard PCs with graphic displays. Two are used to display and issuing of warrants on the northern and southern sections. One is used as a standby and the fourth as a display for the supervisor.
The positions of the trains can be displayed by using a viewer via an internet connection.
The graphic screen displays the real-time position of the locomotives. If no report is received for more than 30min, the dispatcher is warned that there may be a problem with the locomotive.
Track warrants are issued using the mouse on the computer. All warrants are displayed on the screen. The system will not allow a dispatcher to issue a conflicting warrant.
The security module monitors the pre-set condition of the locomotives. Typical alarms will be the reporting of a train that stops between stations or if a locomotive moves faster than 20km/h in a station area.
The warrant is also downloaded via satellite SMS to the display on the locomotive.
