| Liquid floated accelerometer is one of the high accurate accelerometers produced by our nation, which is widely used in inertia navigation systems. However, its measurement circuit is traditional analog one with complex and large-scale hardware module. In order to meet the demand of development of navigation, the paper proposes a design method for embedded accelerometer signal detecting system to accomplish the small, intelligent and liquid accelerometer in inertia navigation field.Firstly, the paper briefly introduces the development, prospect, types, composing and working principle of the accelerometers. And then some details about the characteristics and type of the circuit are also given.Secondly, an innovating method is presented and embedded system is applied to accelerometer with its hardware and software design. |
