基于Bayes后验概率的设备故障诊断模糊分析方法在空调维修中的应用

Application of Fuzzy Analysis Method of Fault Diagnosis Based on Bayes Posterior Probability in Air Conditioner Maintenance

空调设备故障发生具有一定的随机性,故障征兆与故障成因之间以及人的经验判断又存在一定的模糊性.对于空调设备维修必须既要考虑故障发生的随机性因素,又要考虑分析诊断过程中的模糊性因素.鉴于这一考虑将Bayes后验概率表示和模糊分析方法应用于空调设备维修的故障诊断.实例验证了该方法具有一定的实用性.

Air conditioning equipment failure features randomicity.There is a certain ambiguity between fault symptoms and causes of failure and in the judgment based on personal experience.For the maintenance of air conditioning equipment,the randomicity of failure and the fuzziness of diagnostic process should be addressed.In view of this consideration,the Bayes posterior probability and fuzzy analysis method were applied in air conditioning equipment fault diagnosis.The experimental result shows that the method is of practical value.
