IEEE 1451 standards: can the “smart transducer concept be used in system integration for precision agriculture?

As an increasing number of electronic control units with various types of sensors and
actuators are embedded in agricultural machines, systematic and efficient system integration
has become a critical issue. A recently developed agricultural bus standard, ISO 11783,
provides a platform for mobile equipment communications, enabling a plug-and-play
capability for implement controllers made by different manufacturers. This paper further
recommends the use of the IEEE 1451 standards to design “smart transducers” to facilitate
system integration. In this paper, the IEEE 1451 standards are reviewed, the relationship
between ISO 11783 and IEEE 1451 is analyzed, an example of a smart weed sensor
conforming to IEEE 1451 standards is designed, and the advantages and disadvantages of this
implementation are discussed.
