“…It is important, therefore, to consider the next level of implementation: the provision of a hardware description in a high-level language such as VHDL (Rushton, 1995) suitable for compilation into the current level of ASIC technology. The use of a particular language (Handel) for sensor validation architectures is described by Henry (1995) and Henry et al (1996), where the advantage of field-programmable gate arrays (FPGAs) for rapid prototyping is discussed.…”

With the falling cost of microelectronics, intelligent instruments are increasingly used in process control. They are designed to integrate into data networks such as Fieldbus, so that remote users can access internal values and reconfigure their function. It is argued that such instruments should exploit models of the plant’s data generation to achieve optimal filtering, of their own internal behaviour as verified by self-testing, and of the user’s needs. A figure-of-merit for sensor signal processing is defined, and some fundamental results indicating the benefit of appropriate signal models are deduced. The value of validation, in which diagnosed faults affect the measurement status and its uncertainty, is emphasized. Examples of a self-validating thermocouple, a dissolved-oxygen sensor and a flow-control valve are described together with some guidelines about practical implementation.

“…The Valcard research programmes at Oxford (Henry, 1995c;Henry et al, 1996) have addressed this issue through the use of a recently developed hardware/ software co-design approach called hardware compilation; the required functionality is defined in software using software tools and techniques (Page, 1996a,b). Research prototypes are implemented using off-the-shelf processors to run software and field programmable gate arrays (FPGAs) to build hardware.…”

“…Development of platform based on programmable hardware. To develop the general‐purpose SEVA sensor hardware platform, in Oxford, the controlling department cooperated with computer laboratory set up the Valcard project (Henry, 1995a, b, 2001; Henry et al , 1996; Zhou et al , 1999), which targeted towards the general‐purpose SEVA sensor hardware architecture based on FPGA. This architecture has a series of calculating units and I/O units.…”

PurposeTo provide an overview of self‐validating sensor technology for researchers and engineers which can help them understand the concept and recent developments of this research area.Design/methodology/approachThe concept of self‐validating (SEVA) sensors, including definition, output parameters and requirement of SEVA sensors are introduced. The differences between SEVA sensors and traditional sensors are given from which we can see many advantages of SEVA sensors. The principium of SEVA sensors is presented by the functional architecture. The research development of SEVA sensors is introduced in two aspects: research development of sensor fault diagnosis and signal reconstruction and research development of SEVA sensor hardware.FindingsSummarizes the methods for sensor fault diagnosis and signal reconstruction in the research of SEVA sensors, and the development steps of SEVA sensor hardware. Indicates the shortages and problems of current research and gives our research and ideas to solve these problems.Originality/valueThis paper provides a detailed description and research information of self‐validating sensor technology for those who want to know and research on this area.
