Positioning of the goniometric monitoring system based on the phase measuring principle

The article provides analysis of the algorithmic support goniometric control systems based on the accelerometers. Disadvantages of the mathematical equations of this class of systems are considered. Application of the accelerometer measurements in conjunction with phase-measurement principle of signal forming is described together with the technique of accelerometers automatic positioning at a goniometric control of complex dynamic objects. On the basis of this method the inclination of each accelerometer relative to the reference coordinate system is calculated. With the help of tensor transformation coefficients are determined to compensate the deviation angle and set a new coordinate system for each accelerometer. An algorithm for the automatic positioning of the accelerometers is provided. This algorithm runs in setup mode prior to performing the basic program of goniometric control system. The advantages of the proposed method application are the low labor intensity of the installing sensors process and ease of positioning and measurement.
