A monitoring and measuring device for an air supply system of a vehicle, in particular a rail vehicle, includes a compressor which is designed to provide compressed air; a defined volume which is situated downstream of the compressor; a shut-off valve which is situated downstream of the defined volume; a pressure sensor which is provided at any desired position on the pressure line between the compressor and the shut-off valve and is configured to measure the pressure that builds in the defined volume. A first or second air drying device, for example, is used as the defined volume. The pressure curve measured by the pressure sensor can indicate whether there is a fault or a leak. A method for monitoring and for measuring parameters of an air supply system of a vehicle, in particular a rail vehicle is also provided.

Monitoring and measuring device, and method for monitoring and for measuring parameters of an air supply system of vehicles, in particular rail vehicles

A system diagnoses and monitors air supply systems and includes a compressor with a drive, which is configured to provide pressurized air for the system, an air dryer, which is configured to remove moisture from the compressed air in the system, at least two sensors, wherein one sensor is configured and arranged to detect a status signal of a component to be monitored, and another sensor is configured and arranged to detect a reference signal relating to the component to be monitored, and an evaluation unit which is configured to evaluate the signals of the sensors. The evaluation unit is also configured to convert the sensor signals into maintenance and control signals based on an evaluation logic, which signals control the operating mode and the maintenance intervals of the air supply system.

System for the diagnosis and monitoring of air supply systems and components thereof

An air supply system having a compressor driven by a motor for producing compressed air, an air drier system for extracting moisture from the compressed air produced, an electronic converter for demand-dependent control of the compressor and analog and/or digital sensors for producing electrical signals, the electrical signals being useful for controlling the electronic converter and for monitoring and controlling the compressor. The electrical signals produced by the sensors are converted in the electronic converter to bus signals that can be provided for evaluation at a bus interface.

Air supply system with electronic converter

A device and method controls the different energy sources for supplying a vehicle with main and auxiliary air, for which compressed air is produced for pressurizing a main air tank and an auxiliary air tank using at least one compressor. That compressor is driven via a respective associated electric motor, wherein the main air is supplied via an external primary energy source and the auxiliary air is supplied at least partially via an internal secondary energy source which is weaker in contrast. There is a shift between the two different energy sources depending on the operating status of the vehicle, wherein the auxiliary air supply is switched off by decoupling the electric motor from the secondary energy source.
