Application of Multi-sensor Data Fusion on Hydraulic Synthetic Test-bed

The linear PN junction temperature sensor was used to collect the oil pool temperature of the hydraulic synthetic test-bed, and a temperature collecting system was designed with multi-sensor data fusion. The temperature detection circuit was given. And the temperature measurements were estimated by the least square weighted fusion estimation algorithm online which can improve the estimation precision of the oil temperature. In such way the algorithm provided a solid foundation for improving the temperature control precision. The simulation results indicate that the data fusion algorithm effectively deals with the congeneric multi-sensor data fusion.
