BUILDING MANAGEMENT SYSTEM DATA NORMALIZATION AND STANDARDIZATION MECHANISM

摘要

An apparatus for detecting faults of components monitored by a building management system (BMS), including an automatic fault detection (AFD) element that is coupled to the BMS, that monitors, in real time, data samples generated by the BMS indicating operative states of the components, and employs the data samples to determine if one or more of the components are faulty. The AFD element includes a run time modeling element and a data normalizing element. The run time modeling element employs the data samples as inputs to execute one or more fault algorithms retrieved from a system configuration model, and generates outputs to the one or more fault algorithms that indicate if the one or more of the components are faulty. The data normalizing element generates and stores for use by the run time modeling element, equations used to normalize the data samples, along with corresponding properties of the data samples.
