CAN接口的双速自整角机/旋转变压器数字转换器

Two-Speed Synchro/Resolver to Digital Converter with CAN Bus Interface

CAN总线接口的双速自整角机/旋转变压器数字转换器,包括信号转换、纠错处理、通信接口单元。信号转换单元把粗精模拟信号转换成数字信号。纠错处理单元对数字信号组合纠错,得到与轴角对应的19位并行二进制数码。通信接口单元把相应二进制码转换成可与其他系统直接通信的信号。以满足数字伺服控制系统的轴角测量。

This paper introduces one two-speed Synchro/Resolver to Digital Converter with CAN bus interface. The converter consists of signal converter, logic processor and communication interface unit. The signal converter converts the analog signals from angle measure sensor into digital format. The logic processor combines the output of the coarse and fine converter to parallel binary codes which correspond to shaft angle. The communication interface unit converts the binary digit into information which can communicate with the other systems. Thus, it can meet conveniently the need of the angle measure of the digital servo control system.
