摘要
利用轴角-数字转换芯片AD2S82A和旋转变压器,可以组成高精度的多通道测角系统。介绍了这种测角系统的组成和工作原理,研究了它与DSP处理器的接口问题,并利用三态锁存器和单脉冲触发芯片,设计出了一种适用于多通道系统的高速接口电路,解决了DSP一次读取多片AD2S82A所造成的大量时间延迟问题。
Using the resolver-to-digital converter AD2S82A, design a multi channel angle measuring system. Introduced the principle of this angel meastaing system tirst. Then discussed the interface circuit between the AD2S82A and the DSP controller in detail. At last, gave a multi channel and high speed interlace circuit which is composed of 3-state latches and monostable mulfivibratores.
