Control and monitoring systems base their decisions on the information provided by transducers. These signals must be acquired, processed and transmitted. There is an exchange between sensor signal processing and data rate, more signal processing inside the transducer implies lower data rate over the networks. This paper presents the standard IEEE 21451-001 whose main purpose is to extract knowledge of transducer signals that can be shared with others to increase system reliability, infer shapes, normal/abnormal states and to provide a normalized building structure for extracting knowledge. This standard extracts information directly from sampling based on a more complete structure. The standard is described highlighting the purpose and the main algorithms.

Abstract
Control and monitoring systems base their decisions on the information provided by transducers. These signals must be acquired, processed and transmitted. There is an exchange between sensor signal processing and data rate, more signal processing inside the transducer implies lower data rate over the networks. This paper presents the standard IEEE 21451-001 whose main purpose is to extract knowledge of transducer signals that can be shared with others to increase system reliability, infer shapes, normal/abnormal states and to provide a normalized building structure for extracting knowledge. This standard extracts information directly from sampling based on a more complete structure. The standard is described highlighting the purpose and the main algorithms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
