摘要：旋转变压器作为一种精密角度传感器，可应用在环境恶劣的军工及高端工业领域，目前旋转变压器测角系统未能输出与光栅编码器兼容的ABZ三相脉冲接口信号，这限制了其应用。本文提出一种新型解码装置，以AD2S1210芯片构建传感处理单元与旋转变压器匹配后实现激励及模数信号的转换，随后再通过基于stm32微处理器的主控单元对模数转换后的数字信号进行融合处理成角度值，最后再经由基于逻辑门电路以及AM26LS31芯片构成的脉冲转换单元将角度值转换为可与光栅编码器兼容的ABZ三相脉冲接口信号，从而大幅提升旋转变压器测角系统的市场竞争力。

Abstract: As a kind of precision angle sensor, resolver can be used in the military industry and high-end industry field with bad environment. At present, the resolver angle measuring system fails to output the ABZ phase pulse interface signal compatible with optical encoder, which limits its application. This paper proposes a new decoding device, using ad2s1210 chip to build sensor processing unit to match with resolver to realize excitation and analog-to-digital signal conversion, then using STM32 microprocessor-based master control unit to convert the digital signal after analog-to-digital conversion into angle value, and finally through the pulse conversion unit based on logic gate circuit and am26ls31 chip to convert the angle value into ABZ three-phase pulse interface signal compatible with the circular optical grating device, The market competitiveness of resolver angle measuring system is improved greatly.
