摘　　要：本文介绍一种基于专用RDC芯片ADS1210进行轴角解码的旋转变压器接口卡。分别从旋转变压器原理和RDC解码原理进行阐明,主要描述接口卡的硬件设计和软件功能。目前该接口卡已成功作为速度和角度编码器,应用于电机的速度闭环控制及收放绳缆长度的计量。A rotary transformer interface card based on ADS1210 chip RDC will be introduced. On the basis of explaining the principle of resolver and the RDC decoding principle, the hardware design and the software function of the interface card are detaited. At present, the interface card has been successfully used in the motor speed closed-loop control and the measurement of retractable cable length as the speed and angle encoder.
