根据激光测距机的结构和功能特点 ,应用贝叶斯决策理论研究出一种建立激光测距机故障字典、快速实现故障诊断的方法。该方法普遍适用于已有维修经验积累的激光测距机常见故障诊断和维修决策 According to the structure and function of laser range finder, a method of establishing fault dictionary of laser range finder and fast fault diagnosis is developed by using Bayesian decision theory. This method is generally applicable to the existing fault diagnosis and maintenance decision-making of laser range finder with accumulated experience in maintenance
