Abstract
The invention relates to a sensor network in an aircraft, which comprises several sensor nodes that communicate with a central data collection and evaluation unit via a radio transmission path. Data transmission can take place in various ways. For example, different frequency ranges are provided, from which the respective frequency range enabling the best data transmission quality is selected.
Claims17
A sensor node for a wireless sensor network for acquiring measured values in an aircraft, wherein the sensor node comprises:
- a sensor unit for acquiring the measured values;
- a power supply unit for supplying the sensor node with electrical energy;
- a transmitting and receiving unit for wirelessly transmitting the acquired, pre-processed measured values to a central data collection and evaluation unit.
A sensor network for an aircraft, wherein the sensor network comprises:
- a plurality of sensor nodes and a central data collection and evaluation unit for collecting and evaluating the transmitted measured data, wherein the sensor nodes comprise:
- a sensor unit for acquiring the measured values;
- a power supply unit for supplying the sensor node with electrical energy;
- a transmitting and receiving unit for wirelessly transmitting the acquired, pre-processed measured values to a central data collection and evaluation unit.
A method for ascertaining a state of a system component in an aircraft, wherein the method involves the following steps:
- supplying a sensor node with electrical energy by way of a power supply unit in the sensor node;
- acquiring measured values in the area of the system component via the sensor node;
- wirelessly transmitting the acquired measured values to a central data collection and evaluation unit.
