摘　　要：针对月面采样机械臂中的角度传感器——旋转变压器,设计了数字解码电路。为解决电路中数字解码芯片AU6802N1的不足,提出一种可直接给出当前位置相对参考位置的角度解算方法。详细介绍了数字解码电路和角度解算方法的实现过程。通过机械臂腕关节的角度检测试验,验证了电路设计的合理性及角度转换方法的可行性。The digital decoding circuit was designed for the angle sensor, rotary transformer of lunar surface sampling arm. In order to solve the defect of the digital decoding chip AU6802N1, an angle solving method, which can directly give the current position relative to the reference position was proposed. The realization proces of digital decoding circuit and angle solving method was introduced in detail. The angle testing of wrist joint for manipulatoris was adopted to verify the rationality of the circuit design and the feasibility of the angle conversion method.
