Diagnostic information model of a military vehicle

This study presents a diagnostic concept, the cybernetic structure and the physical model of the Autonomic Logistics System, a diagnostic sub-system implemented in the Tarpan Honker military vehicle. The system supports the driver in the process of making decisions regarding the vehicle's condition and key operating parameters. The information model reporting on the status and faults of power transmission system components will not identify limit state values. Limit state values will be identified after the vehicle has been tested with an implemented diagnostic system. An RS-485 type communication and data transmission system with linear (serial) half-duplex technology was designed for the proposed monitoring and diagnostic system. The developed data transmission topology (number of transmitters and receivers) accounts for the vehicle's unique structure, operating requirements, system functionalities and structural feasibility. The proposed transmission system supports quick data transfer between modules (devices) monitoring selected systems and mechanisms. The system minimizes the number of sensors and signal cables through the multiple use of measuring sensor signals. The proposed system is an open structure which supports data transfer between control devices supplied by different manufacturers;
