Cyberphysical network for crop monitoring and fertigation control
| Resumo: | Fertigation 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. |
