根据双通道旋转变压器的工作原理,设计了一种双通道旋转变压器的解码系统。该系统以AD公司生产的AD2S80A作为基础,利用其高精度模数转换功能将旋转变压器的正余弦模拟信号转换成二进制数字信号输出,并使用CPLD对AD2S80A解码后输出的并行数据进行整合、运算与误差补偿。文中给出了双通道旋转变压器解码系统的解码原理,并根据解码原理设计了硬件构成并给出了误差补偿软件流程图,为双通道旋转变压器高精度解码系统的实现提供了一种可行方法。

A decoder system with double entry revolving transformer is designed based on the principle of double entry revolving transformer. The system converts revolving transformer input sine and cosine signals into a parallel natural binary digital word using the high accuracy analog digit conversion function of AD2S80A convert which is produced by the AD Company. And the parallel data from decoded AD2S80A is performed combination, calculation and error compensation using CPLD. The decoding principle of the double entry revolving transformer decoder system is introduced. The hardware combination and error compensation software flowchart are designed based on decoder principle to provide a feasible method to high accuracy decoder system of double entry revolving transformer.
