Provisioning IEEE Smart Transducer Standards (P21451.1) to Include Health Metrics via HEDS

Abstract

Rapid evolution of Internet of Things (IoT) devices places new demands on the ease of networking very large numbers of devices. The IEEE 1451 family of smart transducer standards for sensors and actuators is evolving to keep pace. One of the most important innovations within the standards is the transducer electronic data sheet (TEDS), which conveys essential device information. For distributed networks, the health of devices is of increasing concern as a means to for assuring measurement and control actions. This paper describes the adaptation of the TEDS concept to a health electronic data sheet (HEDS) that is to be proposed as part of ongoing standards update activities. The HEDS has a lexicon of anomalies and associated measures, which an application can access to support the health functions. Pushing the use of HEDS to edge devices can distribute health assessment across all levels of a system hierarchy.
