Empezando a trabajar con NB-IoT
Posted on by albarc

Dentro del proyecto Sensoriza desde el grupo B105 hemos empezado a trabajar por primera vez con la tecnología Narrowband-IoT (NB-IoT).

NB-IoT es un estándar promovido por 3GPP que reutiliza una pequeña parte del espectro LTE. Por tanto, con un pequeño cambio en las estaciones base, proporciona el mismo alcance geográfico que la tecnología móvil 4G actual. La conectividad que proporciona es de muy bajo ancho de banda y baja tasa de datos, a la vez que ofrece una cobertura muy profunda llegando a lugares subterráneos o zonas rurales remotas. Por lo tanto está especialmente diseñada para dispositivos autónomos del mundo del internet de las cosas, como contadores inteligentes, alarmas, agricultura conectada, etc.

Nuestro objetivo es dotar a las máquinas de conservación y mantenimiento de carreteras de un módulo NB-IoT mediante el que puedan transmitir la información recogida por sus sensores ambientales a un centro de control. Utilizando esta tecnología tendremos conectividad desde las carreteras de montaña remotas donde se realizan la mayor parte de actuaciones de vialidad invernal, lo que hasta ahora no era posible.

Como pasos iniciales estamos trabajando con dos módulos de dos fabricantes diferentes. En primer lugar tenemos un módulo BC95 de Quectel, que nos ha facilitado su distribuidor en España Monolitic. Por otro lado estamos utilizando una plataforma basada en Arduino que incorpora un módulo SARA-N211 de u-blox. Vodafone, que es la principal compañía telefónica que está implantando la tecnología NB-IoT en España, nos ha proporcionado dos tarjetas SIM para hacer pruebas de conexión con su red.

ROBIM: Autonomous robots to inspect and evaluate buildings with BIM integration
Posted on by elena

 

The main challenges to overcome in building rehabilitation refer to the use of inefficient traditional techniques and processes as well as to the lack of updated qualitative and quantitative building information. Additionally, building surroundings and facades usually include vulnerable and geometrically complex elements that jeopardize a direct access to them for rehabilitation purposes. This is a critical aspect as the energetic behavior of a building is intimately related to its design and the materials used, hence when materials become functionally or energetically obsolescent, rehabilitation is absolutely necessary so to achieve a minimum energetic efficiency.

In this context, the main objective of the ROBIM project is to develop an automated robotic system that eases the acquisition of detailed and representative information about the state of conservation and composition of enclosures of the building. This system will allow to cut costs
regarding auxiliary equipment used in order to safely access to surroundings of the building, applying state-of-the-art non-destructive inspection techniques and integrating all the information obtained in a digital platform based in BIM methodology. Hence, it will be developed a global solution capable to successfully diagnose the state of a building and provide information in order to effectively decide the typology and scope of the rehabilitation tasks to be performed.

ALL-IN-ONE. A low-cost and extended information integrated traffic monitoring platform
Posted on by guilja

 

Traffic information has multiplied by three its volume market in the last five years. It is also expected that will continue growing greatly in the next years.

However, there are some fields still to be studied and probably exploited regarding traffic information. Such is the case of the integration of both the number of cars and their proper identification.

That is the starting point for the “All in One” project whose objectives are to create an integral traffic monitorization platform with low cost hardware and extended information.

The hardware platform developed will have one radar device for counting vehicles and a Bluetooth interface for identifying them. With this data available and using data integration techniques it will be possible to achieve a level of traffic information yet unknown.

Our group, the B105 Electronic Systems Lab is the one in charge of designing and developing the low-cost radar system. This system includes the electronic for adapting and handling the RF signals as well as the processing modules and digital filters for those signals.

In this project, there are other research groups and some companies involved. As research groups, we are working together with i3-UPM and CEI. The companies we are collaborating with are ACEINSA, KINEO and IPS. This consortium will allow to achieve the project objectives by integrating some partners with expertise in each of the modules of the whole system.

DEPERITA – An intrusion alarm system to improve safety in road work zones
Posted on by albarc

Road traffic accidents are one of the main causes of death and disability worldwide and you can learn this here now from this post. Workers responsible for maintaining and repairing roadways are especially prone to suffer these events, given their exceptional exposure to traffic.

The goal of this project is to develop an intrusion alarm system to improve safety in road work zones. It consists of several nodes equipped with ultrasonic sensors to detect possible vehicle breaches in the perimeter. In addition, we will develop individual warning devices to be worn by every worker that will be wirelessly connected to the detector nodes. This way, in case of a vehicle invading the work zone, each worker can be effectively and timely warned in order to make it to safety.

This project emerged from Jose Martin‘s MSc thesis, and later has been funded by the 2015 AEESD public call. Its official details are as follows:

Title: DEPERITA – DEtección PERImeTral para el Aviso a trabajadores en obras lineales
Code: TSI-100503-2015-0039
Duration: October 2015 – December 2017
Partners: Valoriza Infraestructuras and Universidad Politécnica de Madrid (B105-ESL)
Financing entity: Ministerio de Industria, Energía y Turismo (AEESD 2015)

LÁZARO: Development of an innovative ICT system for the detection of architectural barriers and monitoring based on augmented reality
Posted on by albarc

 

LÁZARO is a project carried out alongside Valoriza Servicios a la Dependencia S.L.U., with the objective of developing a system to automatically detect architectural barriers making use of computer vision and augmented reality. It will integrate the detection provided by sensors and images and the display of an augmented reality layer, together with a warning and checking system for the barriers.

In addition to the first objective, the project pursues another important goal, the development of a wireless sensor network to monitor the living conditions of people with special needs, such as elderly or disabled people. Therefore, the system will result in an integral solution for assisted living facilities and residences, although it can be applied to several other environments.
