IEEE 1451

IEEE 1451 er en mængde af smart transducer grænsefladestandarder udviklet af Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society’s Sensor Technology Technical Committee, der beskriver en mængde af åbne, fælles, datanetuafhængige kommunikationsgrænseflader til at forbinde transducerer (sensorer eller aktuatorer) til microprocessorer, instrumentationssystemer og styrings/felt-datanet.

Et af de centrale elementer af standarderne er definition af Transducer electronic data sheet (TEDS) for hver transducer. TEDS er en "hukommelsesenhed" forbundet til transduceren, som gemmer transducer identifikation, kalibrering, korrektionsdata og producent relateret information. Målet med IEEE 1451 standard familien er at tillade adgang til transducerdata via en fælles mængde af grænseflader, hvad enten transducerne er forbundet til systemer eller datanet via fastnet eller trådløst.

IEEE 1451 anbefales af NIST, IEEE og mange amerikanske federale agenturer.^[1]^[2]^[3]^[4]^[5]
