飞机上各传感器所测量的参数是相互联系、相互影响的。介绍飞机上空速表、转速表、进气压力表、升降速度表、平衡传感器以及机载航姿传感器之间的相互关系,分析表明机载传感器之间是可以进行数据融合的。提出通过采用最小一乘法将这些传感器的数据进行融合的方法,提高机载传感器的应用效率,也提高传感器仪表的可靠性,能够最大限度的保证飞行安全,具有比较重要的应用意义。
The parameters measured by the sensors on the aircraft are interrelated and influence each other. The correlation between the airspeed tachometer, tachometer, intake pressure gauge, ascent and descent speedometer, balance sensor and airborne attitude sensor is introduced. The analysis shows that the airborne sensors can be data fusion. Proposed by using the least squares method to fuse the data of these sensors to improve the application efficiency of airborne sensors, but also improve the reliability of sensor instruments, to ensure maximum flight safety, with more important implications.
