[0029] Preferred embodiment of the invention
[0030] The object of the present invention, as already indicated and as can be seen in the figures, is a device for transforming a container into a smart garbage container that is distinguished by the incorporation of technical innovations and key components that raise the standard in the intelligent and sustainable management of urban waste.
[0031] The device for transforming a container into a smart garbage container, the subject of the invention, integrates advanced technologies that facilitate the precise identification of users, the collection and analysis of data in real time, and efficient interaction with urban infrastructure.
[0032] The device for transforming a container into a smart waste container, which is the subject of the invention, is located on a lid (101) of a container. This lid (101) incorporates an NEC reader (1) that allows for quick and secure user identification via mobile devices or NEC cards, facilitating controlled access to the containers and personalizing the recycling experience. The device for transforming a container into a smart waste container can also incorporate volumetric fill sensors (3) using ultrasonic or infrared technology. The container, which is the subject of the invention, measures the fill level of the containers, enabling efficient waste collection management.
[0033] The device for transforming a container into a smart waste container can also incorporate waste conformity sensors (6) using near-infrared (NIR) spectroscopy and computer vision to verify that the deposited waste corresponds to the appropriate fraction of the container.
[0034] The device for transforming a container into a smart waste container can also incorporate at least one thermal sensor (9). This thermal sensor (9) can detect temperature variations inside the container, which not only helps prevent potential risks, such as fires, resulting from unexpected temperature increases, but also plays a crucial role in identifying the type of waste deposited. The key to this innovation lies in its ability to analyze the thermal profiles generated by each type of waste. For example, organic waste can exhibit a different thermal signature than materials such as glass or plastic, due to decomposition processes and other factors.
[0035] This functionality becomes especially relevant when considering the problem of incorrectly disposed waste. By identifying the specific thermal fluctuations associated with different types of waste, the system could determine if waste has been deposited in the wrong container. For example, if a user deposits organic material in a container intended for glass, the thermal sensor (9), upon detecting a thermal signature that does not correspond to what is expected for that type of container, could alert the system to this error. This would not only facilitate correcting these actions but would also allow for the identification of users who repeatedly make incorrect deposits, thanks to integration with user identification systems, such as the NFC reader mentioned earlier.
[0036] The device for transforming a container into a smart waste container can also incorporate an integrated weighing system (7) configured to measure the weight of the deposited waste, contributing to accurate billing and the collection of statistical data for analysis. The device for transforming a container into a smart waste container, which is the subject of this invention, is manufactured from highly durable, UV-resistant polymers, ensuring a long service life and reducing maintenance requirements.
[0037] Furthermore, the device for transforming a container into a smart garbage container, which is the subject of the invention, features a cover with photocatalytic paint, thus reducing the adhesion of dirt and graffiti, facilitating the cleaning and maintenance of the containers.
[0038] The device for transforming a container into a smart garbage container, the subject of the invention, may also incorporate at least one photovoltaic panel (4), which in the preferred embodiment is flexible, so that the smart garbage container, the subject of the invention, is self-powered by the energy needed for the other components to function.
[0039] The device for transforming a container into a smart waste container, which is the subject of the invention, is configured to be part of an AI-based data management platform. This management platform processes data collected by sensors and stored by a processor (8), and identifies users to optimize collection logistics, pricing, and awareness campaigns. It uses AI algorithms for predictive analysis and proactive recommendations.
[0040] The device for transforming a container into a smart waste container, the subject of the invention, is configured to be connected to an IoT network, such that the smart waste container of the invention can be in bidirectional communication with other containers, with collection vehicles, and with the management platform. For this connection, the smart waste container of the invention comprises a secure and encrypted data communication system (5).
[0041] Considering all the components of the device for transforming a container into a smart waste container, the invention states that this device is compatible with Smart Cities, as it is designed to seamlessly integrate into a smart city ecosystem, interacting with other urban services and contributing to the overall efficiency and sustainability of the city. The technical innovations and key components of the device represent a significant advancement in urban waste management, not only in terms of sustainability and efficiency, but also in promoting greater environmental awareness and citizen participation.This system not only addresses current challenges, but also establishes a solid foundation for future development and adaptation to new needs and emerging technologies.
