Abstract

The invention discloses an angle measurement interface board card for an induction synchronizer, which comprises an induction synchronizer excitation module, an induction synchronizer preamplification module, a sampling and angle resolving module, a peripheral component interconnect (PCI) bus interface module and a power supply. The output end of the induction synchronizer excitation module is connected with the excitation input of an external induction synchronizer; the output end of the induction synchronizer is connected with the input end of the induction synchronizer preamplification module; the output end of the induction synchronizer preamplification module is connected with the input end of the sampling and angle resolving module; the output end of the sampling and angle resolving module is connected with a bridge chip in the PCI bus interface module; the output of the bridge chip is connected with an external industrial personal computer through the PCI bus interface module; and the power supply is connected with the modules respectively. The angle measurement interface board card produces a few sine-wave higher harmonics and ensures accurate waveforms; and the interface board card can be conveniently connected with the industrial personal computer through a PCI bus, so that space is saved, and high anti-jamming capability is achieved.

Description

technical field [0001] The invention relates to the technical field of angle measurement of an induction synchronizer, in particular to an angle measurement interface board of an induction synchronizer. Background technique [0002] In servo control systems such as turntables, radars, and antenna controls, high-precision angle measurement is a prerequisite for precise position control. As an electromagnetic induction sensing element for detecting mechanical rotation angle and displacement, the induction synchronizer has the advantages of high measurement accuracy, fast operation speed, stable and reliable operation, etc. At the same time, because it relies on electromagnetic induction to work, there is no influence of friction, the service life can be almost infinitely long, and there is no special requirement for ambient temperature, humidity, oil pollution, etc., so it is widely used in aviation, aerospace, military and industrial production. [0003] In recent years, wit...
