摘　　要：介绍了Dempster-Shafer(D-S)证据理论数据融合算法的基本原理,在此基础上以电压-码转换电路板为被诊断对象,探索了基于D-S证据理论多传感器数据融合算法的某系统电路故障元器件诊断方法。诊断结果表明D-S证据理论多传感器信息融合算法可有效地提高故障模式的识别能力,使故障元器件得以有效定位。The basic principle of the Dempster - Shafer （D - S） evidence theory data fusion algorithm is introduced. Taking the voltage - code circuit of a certain type of system as object for diagnosis, we studied the diagnosis method for failed elements of the system by using D - S evidence theory data fusion algorithm. The diagnosis result indicated that the D - S multi - sensor integration and fusion could improve the identification capability for fault modes effectively, and thus could locate the position of the failed elements precisely.
