- Chain of Trust: Integrating IoT and Blockchain to Certify Wild Mushroom Growth QualityPublication . Rosse, Higor Vendramini; Camargo, Caio; Gonçalves, Estefânia; Sabiri, Khadija; Coelho, João PauloThis paper presents the preliminary results of the study developed within the scope of the ”Safe2Taste” project presenting the main concept of hardware and software architectures. The project aims to build a monitoring system supported by IoT technologies and covered by a security layer through interaction with a blockchain network to be applied in an edible mushroom production system. The hardware and software components were validated in the laboratory and taken to domestic production for the concept phase. the impacts caused by the inconsistent production management are in the analysis phase as the data collection is not finalized. At this stage, the implementation of low-cost IoT nodes is intended for collecting and monitoring parameters, these parameters are sent via the MQTT protocol to the cloud, starting the blockchain mining process and storing the mining result in an immutable database. The information from monitoring, as well as the keys generated in blockchain mining, will be presented in an intuitive way through a user interface built using the NODE-red framework.
- Cyberphysical network for crop monitoring and fertigation controlPublication . Rosse, Higor Vendramini; Coelho, João Paulo; Duarte, LuísFertigation is a cultivation technique that uses the precise application of nutrient solutions according to the requirements of the plant, environmental conditions and substrate. The use of this technique has become popular due to the advantages promoted, which include the reduction of fertilizers, phytopharmaceuticals and water consumption. However, this performance is achieved at the expense of rigorous monitoring and regulation of factors such as nutrient solutions, environmental conditions and the vegetative state of the crop. This work describes the architecture of a network based on agents and cyberphysical elements that will be implemented in a strawberry production unit by fertigation. The system must be responsible for the correct supply of water and agricultural inputs based on local information provided by sets of sensors. Each set of sensors, called a measurement node, is responsible for acquiring information around a given location. The communication of this information is carried out through a wireless network based on the LoRa protocol to a digital platform where the information from all nodes, together with meteorological data, is aggregated and processed. The result of processing this information will lead to the definition of the exact amount of nutrient solution as well as the optimization of the use of water leading to an increase in production efficiency.
- Electronic instrumentation of a swingletree for equid pull load monitoring: a contribution for the welfare and performance of working donkeysPublication . Coelho, João Paulo; Rodrigues, João Brandão; Queijo, Luis; Rosse, Higor Vendramini; Albuquerque, Francisco Braga; Judge, Andrew; Cooke, Fiona; Garrett, ChrisEquids play a fundamental role in supporting livelihoods in many parts of the world. Being able to access the animal’s welfare, especially while performing tasks that involve high levels of physical effort such as those found in agroforestry activities, is of utmost importance. The Donkey Sanctuary, a UK-based international charitable institution, has designed a project that aims to develop a set of tools to evaluate the working conditions of donkeys and mules worldwide. This requires the measurement of several different parameters, including the force exerted by an animal to pull a load during work. This article presents the stages of design, development and implementation of a device capable of carrying out these measurements with minimal human intervention and with negligible impact on the task operating conditions. Data obtained from real fi eld conditions validates the devised measurement method.
- Static analysis of a lamppost according to Eurocode EN-40Publication . Gonçalves, E.S.; Gonçalves, J.; Rosse, Higor Vendramini; Costa, José Joaquim; Jorge, Luisa; Gonçalves, José; Coelho, João Paulo; Ribeiro, J.E.When people move around a town, at some point in their journey they need to cross the road using a dedicated crosswalk. However, crossing is not always done safely due to weather conditions, lack of visibility or distraction. The VALLPASS project, aims to install two lampposts in opposite positions to the direction of crossing, with various functionalities and technological innovations, creating a luminous tunnel for the safe passage of pedestrians. To verify the mechanical resistance of the lighting poles, numerical simulations were performed using the finite element method, where the boundary conditions considered the criteria defined by the European standard EN-40 "Lighting Columns". This standard specifies the loads acting on the column, namely the horizontal forces due to the action of wind according to standard NP EN 1991-1-4:2010 and the vertical forces due to the self-weight of the entire structure. Considering a lighting pole with a square lower section and a cylindrical upper section, with a total height of 7 meters and with a support structure for photovoltaic panels, according to the static analysis performed, a maximum combination of axial and bending stresses of 138.74MPa, was obtained in the connection zone between the square section and the pole shaft. The maximum displacement of 6.9cm, was obtained at the free ends of the photovoltaic panel support structure and a minimum factor of safety of 1.64 in the zone where the combination of axial and bending stresses is more severe.
- Thermal analysis for testing underground battery locationPublication . Gonçalves, E.S.; Gonçalves, J.; Rosse, Higor Vendramini; Costa, José Joaquim; Jorge, Luísa; Gonçalves, José; Coelho, João Paulo; Ribeiro, J.E.The energy storage batteries, employed in solar systems installed on lampposts, are usually placed in devices such as switchboards fixed at an elevation near the top of the column. However, this storage solution becomes inefficient, because it is not possible to guarantee the control of the working temperature of the batteries, due to the low thermal insulation capacity of these storage devices. In this sense, an underground compartment made of concrete, steel plate and rock wool were created, embedded in the foundation of the lamppost, with the purpose of using geothermal energy to maintain an adequate temperature inside the compartment. To verify the temperature inside the battery storage compartment, a thermal analysis was performed, where heat transfer by conduction, convection and radiation was considered. Analyses were performed in steady state, and later, transient state, considering the initial temperatures of the thermal study in the previous steady state. With a storage volume of 1m3 and the base of the compartment at a depth of 2m, it was verified that it is possible to use geothermal energy to cool or heat, depending on the season, a system through geothermal energy. Considering a typical day in July, with room temperature of 35oC, a reduction of approximately 8oC was obtained inside the storage compartment, compared to the ambient temperature.
