Designing an on-board computer for an armored personnel carrier

Abstract

Timely and accurate solution of the tasks facing the Russian Guard is impossible without a good state of military equipment. The Kupol monitoring system used by the Russian Guard is intended only for monitoring the location of mobile objects using GLONASS / GPS satellite navigation systems, for transmitting navigation information over mobile radio communication networks. Currently, the condition of the armored personnel carrier (BTR-80) is monitored periodically, in accordance with the maintenance regulations. However, the condition of an individual vehicle may differ from the average armored personnel carrier, and therefore it became necessary to re-equip the BTR-80 with an on-board computer that accurately diagnoses the wear (serviceability) of equipment and the combat capability of the vehicle’s units. There is a functional connection between the structural parameters and the parameters of the output processes, due to which, according to the parameters of the latter, it is possible to adequately assess the technical state of military equipment (unit), as well as the quality of its work. The nominal parameters of the structural parameters correspond to the nominal parameters of the parameters of the output processes. As the technical state of military equipment (unit) shifts to the worse, the parameters of the output processes can increase (fuel consumption, vibration) or decrease (oil pressure in the engine). The designed monitoring systems of the BTR-80 are grouped by the type of tasks performed or the drive mechanism: engine and transmission, radio communication, electrical equipment, pneumatic systems, hydraulics, and others. The design of the on-board computer is performed on a programmable logic device using the international standard IEC61131-3. The simulation of the relay-contact circuit showed positive results.
