Abstract

The invention relates to a method for measuring the signal angle of a synchro. The method comprise: by using the directly measured voltage values between different signal lines of the synchro and according to the signal expression of the synchro or the transfer function of an electronic SCOTT transformer, deriving the angle formula of an arctangent function containing the voltage values; accordingto the distribution law of the signal function image of the synchro, determining the quadrants of the measured voltage values between the synchro signal; and transforming the angle formula accordingto the quadrants of the synchro signal in order to achieve angle measurement within a range from 0 to 360 degree. The measuring method has a wide voltage and frequency measuring range and high measuring precision. In addition, the measuring method can be realized by a software algorithm, can be installed on various smartphones, is convenient to carry and is especially suitable to be used for outdoor guarantee especially on ships.

Description

technical field [0001] The invention belongs to the technical field of angle measurement of a shaft angle sensor, and relates to a method for measuring the signal angle of a synchro. Background technique [0002] The synchro signal is a common transmission signal in modern shaft angle transformation technology, and it is widely used in the fields of aviation, aerospace, ships, radar and industrial automation. At present, the measurement of the signal angle of the domestic common synchro is based on complex hardware circuits. One is based on a large number of operational amplifiers, analog switches, precision resistors and other components, and adopts the tracking principle to achieve angle position measurement. device; the other is based on components such as operational amplifiers, AD conversion chips, single-chip microcomputers or DSPs, and is an angle measurement device realized through DSP processing. These two kinds of angle measurement devices need complex circuit com...
