The INTELETRACK TELEMETER is an end-of-train monitor system. The system measures the air-brake pressure or vacuum at the end of the train and transmits the information to the driver in the cab via a radio link. More than 500 Inteletrack telemeter systems are in operation in South- Africa, and several systems are in operation in other countries around the world. The Telemeter system can interface to track-side equipment like low cost dragging equipment detectors, hotbox detectors and point switching equipment. A complete telemeter system consists of a cab unit mounted or stowed in the cab of a train where the crew operates and a rear unit mounted with a clamp on the last wagon of the train.
The rear unit consists of a microprocessor, radio modem, radio, pressure transducer, side mounting style clamp and an integral antenna. The Pressure transducer can measure both air brake pressure and vacuum. If the air-pressure changes more than 10Kpa or the vacuum changes more than 5 Kpa, a message is immediately sent to the cab unit every time it changes. If the pressure or vacuum is stable, the cab unit’s display is updated every 60 seconds. The cab and rear units operate as a matched pair. Each of the pair units is coded with an ID number. A cab unit will only decode a message from his corresponding rear unit. All the Telemeters operate on a single frequency. The rear unit can also be fitted with a second short range digital receiver. This receiver can receive messages from track-side equipment and has a range of 50 to 100 meters. This allows for interfacing to low cost track side equipment like dragging equipment detectors and section-clear signals. The INTELETRACK Telemeter system is designed to be a simple, rugged and reliable system. The clamp on the rear unit can fit on all the known types of buffers in Southern Africa. Maintenance is done by changing modules. All components are readily available from local suppliers.

The new INTELETRACK TELEMETER is an end-of-train monitor system. The system measures the air-brake pressure or vacuum at the end of the train and transmits the information to the driver in the cab via a radio link. This new version of the telemeter is designed according to AAR S-5701 specifications. A complete telemeter system consists of a cab unit mounted or stowed in the cab of a train where the crew operates and a rear unit mounted with a clamp on the last wagon of the train. The INTELETRACK Telemeter system is designed to be a simple, rugged and reliable system. Maintenance is done through changing the modules.

GSM/GPS Asset tracker
When information about moving assets is needed, the VI Tracker can be considered. This small unit can fit snugly into small spaces and does not need external connections to a power supply to function, although operational periods may then be limited. The VI Tracker was designed to be a small tracking unit, reporting GPS coordinates and other status messages via the GSM network to a client server via GPRS or to designated cell phone numbers via SMS. The server may be configured to display the information on a web page or to send emails to designated email addresses.
Hardware-wise, the unit consists of two PCBs – one master PCB and one GPS/GSM module. The master PCB features one USB2.0 port, one RS232 port and a real-time clock (RTC) to keep track of time when the GSM network is unavailable or when the GPS does not have signal. The backup battery is not chargeable, but will last for approximately one year when used in backup mode (no external power connected). This may be replaced with a rechargeable super capacitor with a backup lifetime of approximately 10 days. The power management on the master PCB allows recharging of a 3.8V lithium-ion polymer battery over the USB port. Power is selectable between USB power (GSM and GPS off; 5VDC 500mA) and 5V external power (GPS and GSM can now be used; 5VDC 3A). Another option may be to include some sort of storage for logging or other purposes, such as NAND flash memory or a micro-SD card. On request, the PCB may also expand to include a 10/100 Mbps Ethernet port.
Input Voltage 3.6VDC – 6.0VDC (5VDC nominal). Input Current 3A (2A spike for GSM); 500mA USB. Dimensions 70mm x 56mm x 25mm approx without housing. Rate of Reporting Configurable* (three times daily) SIM Card One push-push mini SIM card connector RS232 baud rate 57600 RS232 data 8-bit RS232 parity None RS232 stop bit(s) 1 bit RS232 Flow Control None * Software may be changed upon request.
With a Lithium battery and a reporting rate of 5 minutes (configurable), the unit may operate up to 3 days without a external power source.
