“…As demonstrated by the experimental results, the system is able to track the real-time movement of both a worker as well as of a construction machinery, in indoor as well as outdoor scenarios. With the respect to similar proximity warning solutions used in construction sector based on Bluetooth technology [19] [20] [21] [22], ultrasonic [23] or LoRaWAN devices [24], the proposed solution exploits the use of UWB radio to reach a localization accuracy on the order of 30 cm, at an update rate up to 50 ms, as indicate by the technology provider [25] and by scientific literature Error!

Construction is among the most dangerous industries for the safety of workers. Due to the dynamism typical of construction sites, where workers, materials and equipment resources are often in motion, collisions and contact with moving construction machineries and heavy equipment represents one of the main safety problems. The study described in this paper concerns with the preliminary development of a proximity warning system (PWS) for construction activities, which is based on the implementation of sensing technologies for situation awareness. Preliminary results, the feasibility of the PWS and its practical potential are described, highlighting the needs of a continuous monitoring process and the expectations about the system configuration. The adoption of the Ultra Wide Band (UWB) technology is within the scope of the paper. A front-end loader and an excavator are the construction machineries taken into account for the analysis of the use case, which considers the differences between equipment with fixed and variable geometries in terms of sensor devices. The possibilities for real-time position tracking of workers and equipment in both outdoor and indoor conditions based on the system architecture settings are discussed. Moreover, the compliance of the system architecture with the requirements imposed by the General Data Protection Regulation (GDPR) is described. Future works will validate the system in the context of actual construction sites. Furthermore, factors to be considered when sensing technologies for tracking the position of resources on construction sites are implemented will be evaluated as far as planning and scheduling activities are concerned.

“…In the experiments, a simple part was machined for demonstration. However, in more advanced factories with a huge number of machines and therefore more complex manufactured parts and a more dangerous environment, 30 the manual inspection and control of conformity of machined parts become more challenging. Hence, by using the proposed system, inspection time and cost as well as production quality could be improved dramatically.…”

In manufacturing systems, there are several essential tasks to perform before and after the production process. In traditional systems, these tasks were done manually, which can lead to more resource consumption and the risk of human error; however, advanced manufacturing systems and Industry 4.0 tend toward a more autonomous manner. To ensure the compliance of the machining process and the safety of the personnel as well as the machines at the shop floor, the inspection of the overall factory prior to any machining process and the control of conformity of the manufactured parts are necessary in order to know the status of the manufacturing line. This paper proposes a novel modular smart vision system for machine inspection and conformity control of machined parts. Our system uses smart vision technologies embedded in industrial robots and enhanced with image processing and analysis capabilities.The solution also integrates a user interface for human-machine interactions that has been developed with a modular approach, and is designed, launched, and controlled by the manufacturing execution system, allowing agile and customized configuration. By this new approach, the robot inspects all the machines in the factory to check the status before launching the production plan. After the machining process, the system interprets the in situ dimensional analysis for the machined parts and makes decisions about whether the parts are acceptable or require additional machining.

“…Los sistemas de alertas son creados para detectar fallos o advertir sobre posibles riesgos, los componentes utilizados en su diseño dependen de necesidades específicas claramente identificadas. El sistema de alerta de proximidad desarrollado por investigadores del FUPRE y UNIZIK en Nigeria utilizo un sensor ultrasónico y un microcontrolador Arduino para reducir el riesgo de accidente de los trabajadores mediante un sistema de retroalimentación sobre la proximidad a las zonas de peligro existentes en la empresa [5], los resultados revelaron la necesidad de utilizar más sensores en puntos estratégicos.…”

Resumen Introducción: A raíz de la pandemia ocasionada por el virus Sars-Cov-2, los países han impuesto medidas para que los establecimientos puedan normalizar poco a poco sus actividades en una etapa de transición que apunta a la reactivación económica en el sector turismo. Para la reapertura de los escenarios dispuestos en el turismo cultural, es necesario el estricto cumplimiento del distanciamiento social y evitar las aglomeraciones, razón por la cual resulta indispensable limitar el aforo o la capacidad de visitantes. Objetivo: Presentar la implementación de un modelo de adquisición de datos utilizando un sensor ultrasonido HC-SR04 programado con Arduino para controlar el aforo máximo de turistas en entornos cerrados tales como museos, bibliotecas, parques temáticos, edificaciones, galerías de arte y sitios arqueológicos. Método: Se propuso la implementación de un sistema basado en IoT y analítica de datos en un contexto turístico. La programación con código Arduino permitió la captura y visualización de datos durante de 48 horas. Resultados: Mediante el análisis de la información capturada fue posible alertar el sobrelimite del aforo parametrizado identificando a través de las notificaciones los niveles de riesgo. Conclusiones: El sistema desarrollado permite alertar sobre el aforo máximo en espacios cerrados, generando control y reduciendo la probabilidad de contagio en estos espacios.
