Vehicle Monitoring
There have been one vehicle system implemented and 1 currently being implemented.
Bus Tracking System
This system consisted of a simple X86 based board with an attached radio modem, GPS unit and multiple serial ports. This system was based on a Linux 2.6.22 kernel and highly influenced by Linux From Scratch
The embedded devices consist of two separate units one for installation at bus stop and bus interchanges to report on the arrival and departures time. The second was to be installed on a bus to provide a tracking facility. both units consist of a Radio modem a voice announcement system and a controller for the bus signs. The bus tracking system also has a Wireless LAN card and a GPS unit.
The system is build around a 2.6 Linux kernel running from flash which continuously reports to base-stations. There are separate interface/protocol handlers for each of the serial communication devices. The environment is a hostile environment with strict compliance rules ( IP65).
Vehicle Monitoring with CAN Protocol
This is a current work in progress to provide a device driver for the CAN protocol for vehicle diagnostics.
