Title:
MULTISENSOR MEASUREMENT METHOD AND SYSTEM
Document Type and Number:
Japanese Patent JP2019090812
Kind Code:
A
Abstract:
To provide a multisensor measurement system capable of executing a single evaluation procedure regardless of the sensor type and the number of sensors.SOLUTION: The multisensor measurement system includes: at least one set of n redundant sensors C1, C2, ..., Cn showing the same physical amount for sending n measurement signals; a fusion unit 10 for sending a single multiplexed output signal that is constituted of the n measurement signals by fusing the n measurement signals; and a re-conditional unscented Kalman filter UKF20 that receives the multiplexed output signal, rejects a signal showing a sensor failure, then outputs a signal constituting the best estimated value of the measurement of the physical amount.SELECTED DRAWING: Figure 2
