METHOD AND APPARATUS FOR MONITORING OPERATING DATA OF BOILER BASED ON BAYESIAN NETWORK

摘要

A method and apparatus for monitoring operating data of a boiler system based on a Bayesian network. The method comprises: S1: establishing a boiler system state model according to association relationships between various components of a boiler system and different positions of the components; S2: collecting operating states of the components and of the components at the different positions by means of a sensor, so as to obtain a boiler system observation model; S3: obtaining a boiler system model, combining the boiler system state model and the boiler system observation model; and S4: according to the boiler system model, inferring missing observation data and determining whether the observation data is abnormal. The method and apparatus construct a device-operating model based on a Bayesian network, monitor the correctness of data by means of the model, and completely supply missing data, thereby providing convenience for subsequent device remote diagnosis.
