信息论在沥青砼拌合楼故障诊断中的应用

Application of Information Theory to the Fault Diagnosis of Asphalt Mixing Plant

首先对信息论作了具体的介绍,并对信息熵和熵系数作了详细的阐述。在湖北省路桥公司TITAN 3000型沥青砼拌合楼的故障诊断中,以信息论为依据,对除尘装置前、后负压值和骨料温度、烟气温度这两对反映除尘布袋工作状况和性能的测量数据进行了处理和误差分析,对数据的准确性做出评价。

This paper firstly introduced the information theory, the information entropy and the entropy coefficient. During the faults diagnosis of TITAN3000 asphalt mixing plant belonging to Hubei Construction of Bridge ＆ Road Co. ,Ltd ,based on the information theory, measurement data of negative pressure and aggregate temperature were processed and the error analysis of the data was conducted. At the same time,the data＇s accuracy was evaluated.
