System of monitoring and recording of emergency parameters of engine gearbox of combat vehicle

Technical field

The technical solution relates to the system for monitoring and recording the havai of the third parameters of the engine gearbox of the combat vehicle, especially the oil temperature in the engine lubrication system, the oil pressure m in the engine lubrication system, the coolant temperature, engine operating hours, load operating hours etc.

BACKGROUND OF THE INVENTION

Until now, it was possible to observe the parameters of the engine gearbox of the combat vehicle on the indicators located on the dashboard in the driver's cab, which was very difficult during driving under difficult conditions and the probability of overlooking the off-tolerance state was very high. In combat conditions, monitoring the parameters of the engine gearbox driver virtually impossible. The automatic intervention into the engine gearbox during off-tolerance conditions was not technically ensured. Also, automatic recording of off-tolerance conditions was not performed. This could cause severe damage to the engine gearbox and thus prevent further movement of the vehicle, which in combat conditions led to rapid destruction of the vehicle event. and crew. Since there were no records of extracolerant states, it was not possible to reverse-analyze the course of damage or what preceded it.

The essence of the technical solution

The above-mentioned deficiencies are eliminated by the system of monitoring and recording of emergency parameters of the engine gearbox of the combat vehicle. It is connected to a processor, to which the protection and level converter output is also connected. Outputs are processed from the processor to non-volatile memory for recording operational and emergency data, to the optical status indicator, voice output to the vehicle speech equipment, to the actuators of the vehicle, and to the output for connecting an external evaluation device. The processor can also be connected to an actuator to control the radiator louvre. Monitored engine parameters are engine oil temperature and pressure, engine coolant inlet and outlet and turbocharger temperature and pressure, onboard supply voltage and current, critical fluid temperature, fan condition, operating fluid level, engine operating hours, engine load hours, tachometer status event. next.

Overview of the drawings

The technical solution is explained in the drawing, which shows * the wiring diagram of the system for monitoring and recording the emergency parameters of the engine gearbox of the tank.

Exemplary embodiment

At the input of the level 10 protectors and transducers are output from sensors of monitored parameters of the engine gearbox, namely from the sensor of water and oil temperature, from the sensor 2 of oil pressure, from the sensors of voltage and current of the onboard network. 2-volt sensor 5, switching on the fan, 2-volt sensor 6. operating fluid level, 2-volt sensor 7 engine operating hours, 2-volt sensor 8 engine load hours and frequency * output of tachometer 9. Analog data from protection and level 10 converter The two-valued signals are routed from the protections and the level 10 converter directly to the processor 83. The output from the processor 13 is provided to a non-volatile memory 64, a speech device 65, a vehicle actuator 16 and an external evaluation device 47. The processor 13 is further coupled to the optical indicator 12 and the actuator 18 to control the radiator louvre.

The system for monitoring and recording the vehicle's emergency parameters shall, after switching on the vehicle's on-board network, test its operation and check the most important indicators for the plausibility of the data and report illicit states. It communicates with the crew by means of an optical indicator 12 and via a voice output connected to the tank call device 85. At the end of the test, it monitors the parameters according to the built-in program at several levels and warns the driver by voice and optical output of the need to check the pointers or change the driving style. If the parameter states are off-tolerance, directly endangering the units, the system will ensure that they are shut down in practice conditions by switching off the fuel supply. The system alerts the driver for parameters or combinations that can only negatively affect the service life of the equipment. For all unacceptable conditions, the system records the status, the time it takes, and its time course. The recording remains in the non-volatile memory 14 even after the power supply has been disconnected. The recorded data can be transferred to an external evaluation device 17.
