The Organ Design and Signal Processing Technique of Anti-Acceleration Disturb Gasflow Style Inclination Sensor

This paper introduced the structure principle and the signal processing technique of the omnidirectional gasflow style horizontal Posture Sensor. The heat sensitive resistance was used as heat source and sensitive unit, and the natural convection of the gas was produced in a hermetic chamber. The posture signal of carrier was got and processed by hardware circuit and software compensation technique, so it can measure the omnidirectional horizontal posture of the carrier when the carrier were in any yawing direction. Established the math model and designed program base on the character of the sensor. Realized the anti-acceleration disturb and eliminated 90% of the disturb by the program.
