Applying the Analog Configurability Test Approach in a Wireless Sensor Network Application

Abstract

This work addresses the application of the analog configurability test (ACT) approach for an embedded analog configurable circuit (EACC), composed of operational amplifiers and interconnection resources that are embedded in the MSP430xG461x microcontrollers family. This test strategy is particularly useful for in-field application requiring reliability, safe operation, or fault tolerance characteristics. Our test proposal consists of programming a reduced set of available configurations for the EACC and testing its functionality by measuring only a few key parameters. The processor executes an embedded test routine that sequentially programs selected configurations, sets the test stimulus, acquires data from the internal ADC, and performs required calculations. The test approach is experimentally evaluated using an embedded system-based real application board. Our experimental results show very good repeatability, with very low errors. These results show that the ACT proposed here is useful for testing the functionality of the circuit under test in a real application context by using a simple strategy at a very low cost.

“…A pesar de que el test de circuitos de señal mixta es un campo de investigación activo, un número relativamente bajo de trabajos se han enfocado en el test de ACCs. Entre ellos merecen citarse (Andrade et al, 2005;Tiago R. Balen et al, 2007;Dri et al, 2020;Laprovitta et al, 2014;Lovay et al, 2015). Asimismo, ninguno de ellos ha sido evaluado en el marco del test de filtros pasabandas.…”

Joint Design of Transmission Rate and Control for Wireless Sensor Networked Control Systems

“…In addition, hybrid networks are characterized by both star and mesh topology. It is well known that the advantages (such as flexible installation and maintenance, lost cost) enable WSNCS to be widely used in smart grids, industrial process control, and so forth [6,7]. Based on the different application scenarios, one can determine what type of network topology structures is more appropriate.…”

Star topology network architectures are highly relevant in process industry [6,7], and mesh or hybrid network architecturesbased networked control has been founded in greenhouse applications [8].…”
