Abstract

The invention relates to an autonomous robotic device for disinfection using UV-C radiation and ozone generation consisting of a movable base (1) capable of moving around autonomously or via remote control through an app, carrying a germicidal lamp assembly with UV-C illumination and ozone generator (11) with forced ventilation. Assisted by presence sensors, the device identifies the presence of people or animals and selects which disinfection method to use. In the presence of people or animals, the robotic module switches off the lamps and switches on the forced ozone generation system. The lateral modules (7), when open, allow UV-C irradiation of objects such as tables and seats, inter alia. Its processing system uses artificial intelligence (AI) to guide the module on the paths already taken and establish new routes in the presence of objects, people or animals in its way.

Descrição do problema problem description
[002] O maior problema enfrentado pela humanidade, no limiar do século XXI, é a pandemia em curso ocasionada pelo COVID-19, doença respiratória aguda causada pelo corona vírus da síndrome respiratória aguda grave 2 (SARS-CoV-2). [003] A preocupação atual é grande devido a sua rápida transmissão e contágio mundial e, inclusive, pela inexistência de vacinas ou medicamentos antivirais. Atualmente, a mortalidade é de 2 a 3%. [002] The biggest problem facing humanity, on the threshold of the 21st century, is the ongoing pandemic caused by COVID-19, an acute respiratory disease caused by the coronavirus of severe acute respiratory syndrome 2 (SARS-CoV-2). [003] The current concern is great due to its rapid transmission and contagion worldwide and even the lack of vaccines or antiviral drugs. Currently, mortality is 2 to 3%.
[004] Estruturalmente, o vírus não é único e, de fato, é similar com outros corona vírus como por exemplo ao Severe acute respiratory syndrome (SARS) e Middle East respiratory syndrome (MERS). O corona vírus ode ser combatido utilizando elementos de limpeza tradicionais, mas com muito cuidado devido a sua fácil contaminação, periculosidade e falta de cura. [004] Structurally, the virus is not unique and, in fact, is similar to other coronaviruses such as Severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). The corona virus can be fought using traditional cleaning elements, but with great care due to its easy contamination, danger and lack of cure.
[005] O UV germicida (254nm UVC) é capaz de matar e inativar micro-organismos, destruindo ácidos nucleicos e perturbando o DNA ou RNA, deixando-os incapazes de se replicar e recuperar. O uso de UV-C na área de saúde, para matar bactérias e vírus é clinicamente comprovado através de vários estudos científicos, pesquisas e testes já realizados em laboratórios do mundo todo. O UV-C tem a capacidade de erradicar 99,99% dos microrganismos incluindo bactérias, vírus e patógenos. [006] Diversos estudos apontam a dose necessária de energia UV-C a ser depositada na superfície para matar ou neutralizar os vírus. O valor da dose depende do tipo de vírus. A dose é medida em mJ/cm2, energia por área. O tempo necessário para atingir determinado nível de energia dependerá da irradiância UV- C da lâmpada e da distância.

Restrições de Uso Use Restrictions
[007] A Comissão Internacional de Iluminação (CIE) classificou e subdividiu a faixa do espectro eletromagnético referente à radiação ultravioleta em três regiões para finalidades práticas relativas à magnitude do dano à saúde: UV-C (100 a 280 nm); UV-B (280 a 315 nm) e UV-A (315 a 400 nm). [007] The International Commission on Illumination (CIE) has classified and subdivided the range of the electromagnetic spectrum referring to ultraviolet radiation into three regions for practical purposes relating to the magnitude of harm to health: UV-C (100 to 280 nm); UV-B (280 to 315 nm) and UV-A (315 to 400 nm).
[008] No Brasil, os riscos à saúde ocupacional são determinados pelo Ministério do T rabalho e Emprego (MTE) por meio da NR 15. Dessa forma, os limites máximos de exposição à radiação UV, segundo a ICNIRP, são diferenciados para a pele e para os olhos. Todos os valores são considerados para uma jornada típica de trabalho de oito horas. O limite de exposição radiante efetiva para pele desprotegida, na região do espectro de 180 a 400 nm, não deve exceder 30 J/m2. Este limite é estabelecido para o tipo de pele mais sensível e não patológico. E, o limite de exposição radiante para os olhos desprotegidos, na região do espectro de 315 a 400 nm, não deve exceder a 10 000 J/m2. [008] In Brazil, occupational health risks are determined by the Ministry of Labor and Employment (MTE) through NR 15. Thus, the maximum limits of exposure to UV radiation, according to ICNIRP, are differentiated for the skin and for the eyes. All values are considered for a typical eight-hour workday. The effective radiant exposure limit for unprotected skin, in the range of spectrum from 180 to 400 nm, should not exceed 30 J/m 2 . This limit is established for the most sensitive and non-pathological skin type. And, the radiant exposure limit for unprotected eyes, in the region of the spectrum from 315 to 400 nm, should not exceed 10 000 J/m 2 .
Dosagem necessária segundo artigos publicados Necessary dosage according to published articles
[009] Lâmpadas especiais com alto rendimento de radiação UV-C, feitas em tubo de quartzo transparente, têm a finalidade principal de esterilização de ambientes, de ar, superfícies, indústrias alimentícias, em locais farmacêuticos e médicos, para tratamento de águas, para caixas estéril e locais onde houver a necessidade de esterilização. Estas lâmpadas especiais emitem radiação UV de onda com um pico em 254 nm (UV-C) com ação germicida UV irradiância de 254 nm medido a uma distância de 1 m ao meio da lâmpada de nível, a 20 °C de temperatura ambiente, sem a queima. Entre 0,3 a 3,5 m, a irradiância é inversamente proporcional ao quadrado da distância. [009] Special lamps with high output of UV-C radiation, made in transparent quartz tube, have the main purpose of sterilizing environments, air, surfaces, food industries, in pharmaceutical and medical places, for water treatment, for sterile boxes and places where sterilization is required. These special lamps emit UV wave radiation with a peak at 254 nm (UV-C) with germicidal action UV irradiance of 254 nm measured at a distance of 1 m to the middle of the level lamp, at 20 °C ambient temperature, without the burning. Between 0.3 to 3.5 m, the irradiance is inversely proportional to the square of the distance.

Ozônio Ozone
[011] Ozônio pode matar diversos micro-organismos como bactérias, vírus e fungos. Isso ocorre devido ao seu alto poder oxidante. O mecanismo de ação do ozônio contra bactérias e fungos, por exemplo, ocorre “de fora para dentro”. O ozônio destrói a parede celular desses micro-organismos, via reações químicas de oxidação, até penetrar ao interior do micro-organismo, danificando também agentes vitais para sua vida, culminando assim em sua morte. [011] Ozone can kill various microorganisms such as bacteria, viruses and fungi. This is due to its high oxidizing power. The mechanism of action of ozone against bacteria and fungi, for example, occurs “from the outside to the inside”. Ozone destroys the cell wall of these microorganisms, via chemical oxidation reactions, until it penetrates into the interior of the microorganism, also damaging vital agents for its life, thus culminating in its death.
[012] No caso dos vírus, a ação ocorre da mesma forma. Quando em contato, o ozônio destrói o vírus difundindo-se através do envelope virai e/ou do revestimento proteico (capsídeo virai) em direção ao núcleo de ácido nucleico, resultando em danos ao DNA ou RNA virai. Comparado com a radiação UV-C, o ozônio pode passar através dos tecidos, chegando a vírus e bactérias que a UV-C não atingiria. [013] Dosagens seguras de ozônio em ambientes são indicados pela NR 15 com uma exposição máxima de 0,08ppm (partes por milhão) para jornadas de trabalho de 48 horas por semana e devem ser considerados fatores no ambiente. O ozônio em doses mais altas pode causar tosse, dor no peito, falta de ar e irritações na garganta, além de piorar condições de asma. Os níveis dos sintomas variam de acordo com as pessoas, sendo que, mesmo pessoas saudáveis podem apresentar problemas quando expostas ao ozônio. A norma recomenda o uso de dispositivos sensores que alertem aos usuários os níveis acima de 0,1 ppm. [012] In the case of viruses, the action occurs in the same way. When in contact, ozone destroys the virus by diffusing through the viral envelope and/or the protein coat (viral capsid) towards the nucleic acid nucleus, resulting in damage to the viral DNA or RNA. Compared to UV-C radiation, ozone can pass through tissue, reaching viruses and bacteria that UV-C would not reach. [013] Safe dosages of ozone in environments are indicated by NR 15 with a maximum exposure of 0.08ppm (parts per million) for working hours of 48 hours per week and must be considered factors in the environment. Ozone in higher doses can cause coughing, chest pain, shortness of breath and sore throat, and worsen asthma conditions. Symptom levels vary from person to person, and even healthy people can experience problems when exposed to ozone. The standard recommends the use of sensing devices that alert users to levels above 0.1 ppm.
Estado da técnica [014] Atualmente existe uma infinidade de produtos químicos disponíveis no mercado para aplicação manual durante a limpeza de ambientes. Por serem de aplicação manual, a eficácia da desinfecção depende da sua correta utilização e aplicação em todas as superfícies presentes dentro de uma sala. Este processo de aplicação é demorado e cansativo, o que compromete sua eficiência. State of the art [014] Currently there are a multitude of chemicals available on the market for manual application during cleaning environments. As they are manually applied, the effectiveness of disinfection depends on their correct use and application on all surfaces present in a room. This application process is time-consuming and tiring, which compromises its efficiency.
[015] No intuito de melhorar a desinfecção de ambientes, cita-se um dispositivo para desinfecção de superfícies patenteado no documento BR 202014006540-2 U2, que trata basicamente de um bastão que, ligado em uma tomada, utiliza uma lâmpada UV-C. A lâmpada, ao ser aproximada das superfícies, permite a desinfecção das mesmas. O dispositivo possui uma capa protetora para direcionar a luz apenas para a superfície de interesse e não para a pessoa que estiver manuseando. [015] In order to improve the disinfection of environments, a device for surface disinfection patented in document BR 202014006540-2 U2 is cited, which basically deals with a stick that, plugged into a socket, uses a UV-C lamp. The lamp, when approached to the surfaces, allows their disinfection. The device has a protective cover to direct light only to the surface of interest and not to the person handling it.
[016] Podem-se citar outros mecanismos muito mais eficientes como o descrito na patente BR 10 2018 068501 5 A2, intitulada “Sistema automatizado de gerenciar unidade móvel de esterilização UV-C”, que trata de um módulo móvel com lâmpadas UV-C que pode ser transportado manualmente por uma pessoa. O módulo é posicionado no local onde deseja-se desinfectar. No intuito de evitar lesões a pele e olhos do operador, o sistema é acionado remotamente por um controle sem fio. O tempo de desinfecção depende da distância entre as superfícies e as lâmpadas do sistema. O equipamento precisa ser ligado numa tomada de energia (220 - 127 VAC). [016] Other much more efficient mechanisms can be cited as described in patent BR 10 2018 068501 5 A2, entitled "Automated system for managing mobile UV-C sterilization unit", which deals with a mobile module with UV-C lamps which can be carried manually by one person. The module is placed in the place where you want to disinfect. In order to avoid injuries to the operator's skin and eyes, the system is remotely activated by a wireless control. Disinfection time depends on the distance between surfaces and system lamps. The equipment must be plugged into a power outlet (220 - 127 VAC).
[017] Já a patente BR 202018012190-7 trata de um “Aparelho emissor de luz ultravioleta-UV-C para a desinfecção de ar e superfícies hospitalares e similares” que consiste em um módulo móvel que possui 20 lâmpadas UV-C e pode ser posicionado manualmente por um operador. Seu acionamento também é remoto, via tablet com login e senha. O dispositivo possui sensores de presença para desligar as lâmpadas em caso de presença de pessoas nas redondezas. O equipamento precisa ser ligado numa tomada de energia (220 - 127 VAC). [017] Patent BR 202018012190-7, on the other hand, deals with an "Ultraviolet-UV-C light emitting device for the disinfection of air and hospital surfaces and the like" which consists of a mobile module that has 20 UV-C lamps and can be manually positioned by an operator. Its activation is also remote, via tablet with login and password. The device has presence sensors to turn off the lamps in case of presence of people in the surroundings. The equipment must be plugged into a power outlet (220 - 127 VAC).
[018] Encontram-se métodos robóticos alternativos de limpeza aplicados a ambientes como a patente estadunidense US7805220B2 intitulada “Robot vacuum with internai mapping system” que consiste em um robô aspirador de pó com sistema de vácuo, vassourinhas e lâmpada UV. Este robô possui um sistema de mapeamento que permite percorrer a sala toda no intuito de aspirar pó presente no piso e ao mesmo tempo desinfectar com a lâmpada UV. A limitação desta solução está na sua aplicação desinfetante apenas no piso, redução de sua eficiência conforme a lâmpada suja pela própria poeira aspirada e o tempo necessário para desinfecção, já que, devido ao seu sistema de mapeamento, não garante que o robô passe mais de uma vez no mesmo ponto. [018] There are alternative robotic cleaning methods applied to environments such as the US patent US7805220B2 entitled "Robot vacuum with internal mapping system" which consists of a vacuum cleaner robot with vacuum system, brooms and UV lamp. This robot has a mapping system that allows it to go through the entire room in order to vacuum the dust present in the floor and at the same time disinfect with the UV lamp. The limitation of this solution lies in its disinfectant application only on the floor, reduction of its efficiency according to the lamp dirty by the dust itself, and the time required for disinfection, since, due to its mapping system, it does not guarantee that the robot will pass more than once at the same point.
[019] Existem também patentes como a US20120189491 A2, intitulada “Robotic pool cleaner with internai ultraviolet water sterilization” que utiliza o mesmo conceito do dispositivo da patente anteriormente citada, mas aplicado a piscinas para trabalho submerso no intuito de desinfecção da água. [019] There are also patents such as US20120189491 A2, entitled "Robotic pool cleaner with internal ultraviolet water sterilization" which uses the same concept of the device of the aforementioned patent, but applied to swimming pools for submerged work in order to disinfect the water.
[020] Outro método alternativo para desinfecção de salas é o descrito na patente estadunidense US20080056933A1 , intitulada “Self-Propelled Sterilization Robot and Method”, a qual se refere a um dispositivo ou módulo que pode ser ou não autónomo. O principal método de desinfecção desta solução são as lâmpadas UV- C utilizadas. Esta solução já possui sensores de presença por infravermelho para detecção de pessoas ou animais, no intuito de impedir a exposição da radiação de UV direta em rosto e pele. Caso for detectada a presença de alguma pessoa, as lâmpadas são desligadas. [020] Another alternative method for disinfecting rooms is described in the US patent US20080056933A1 , entitled "Self-Propelled Sterilization Robot and Method", which refers to a device or module that may or may not be autonomous. The main disinfection method for this solution is the UV-C lamps used. This solution already has infrared presence sensors for detecting people or animals, in order to prevent exposure to direct UV radiation on the face and skin. If the presence of any person is detected, the lamps are turned off.
[021] Destaca-se também o sistema proposto na patente estadunidense US10500296B2, intitulada “Internai sanitizing and communicating”, pensada na aplicação da radiação UV-C em aeronaves e outros meios de transporte como ônibus e trens devido ao seu tamanho e a asas horizontais que permitem distribuir melhor a radiação sobre os bancos em ambos lados. Este dispositivo destaca-se também por propor um capuz plástico transparente com filtro UV que oferece proteção ao operador enquanto o dispositivo é empurrado ao longo do corredor. [022] Com isso, com base nas soluções do estado da arte descritas acima, observa-se que todas desligam as lâmpadas em caso de presença de pessoas por questão de segurança. Quando for ligada novamente, existirá um tempo de reaquecimento, ocasionando uma irradiação menor até a lâmpada chegar ao ponto de potência nominal. Também se verifica a falta de integração dos dispositivos com um sistema de gestão que facilite a gestão das atividades de desinfecção. Finalmente, e não menos importante, deve-se destacar que a maioria dos sistemas citados apenas utilizam lâmpadas de radiação UV como método de desinfecção, o que impossibilita seu uso na presença de pessoas ou animais na sua proximidade. Novidades e objetivos da invenção [021] Also noteworthy is the system proposed in the US patent US10500296B2, entitled "Internal sanitizing and communicating", designed to apply UV-C radiation in aircraft and other means of transport such as buses and trains due to its size and horizontal wings that allow better distribution of radiation over the benches on both sides. This device also stands out for offering a transparent plastic hood with UV filter that offers protection to the operator while the device is pushed along the aisle. [022] With this, based on the state of the art solutions described above, it is observed that all turn off the lamps in case of presence of people for safety reasons. When it is turned on again, there will be a reheat time, causing less radiance until the lamp reaches the nominal power point. There is also a lack of integration of devices with a management system that facilitates the management of disinfection activities. Finally, and not least, it should be noted that most of the systems mentioned only use UV lamps as a disinfection method, which makes it impossible to use them in the presence of people or animals in their vicinity. News and objectives of the invention

Acrescenta-se também que, quando o presente robô operar no modo autónomo, sua rota poderá ser pré-programada mediante a criação de mapas virtuais, mas também poderá se locomover escaneando o ambiente e utilizando tags RFID (identificação por radiofrequência) que, previamente adesivados, indicam os pontos críticos de um determinado ambiente, onde o dispositivo deverá aumentar o tempo de exposição dada sua relevância. It is also added that, when the present robot operates in autonomous mode, its route may be pre-programmed by creating virtual maps, but it will also be able to move around by scanning the environment and using RFID tags (radio frequency identification) which, previously tagged , indicate the critical points in a given environment, where the device should increase the exposure time given its relevance.

Descrição da invenção [025] A solução proposta consiste em um dispositivo robótico que utiliza iluminação UV-C e gerador de ozônio forçado. O gerador de ozônio emite constantemente para o ambiente, mediante ventilação forçada, levando ozônio para todos os locais por onde for passar com o equipamento. Na ausência de pessoas, os locais podem ser desinfectados em poucos minutos utilizando a luz UV-C num raio de cobertura de 3,5 m. Durante o tempo em que as lâmpadas UV- C estão ligadas, o gerador de ozônio fica desligado. Está comprovado, no mundo todo, que a eficiência da luz UV-C e do ozônio é altíssima comparada com os métodos de limpeza tradicionais. A descontaminação com UV-C é um método limpo e eficaz comparado com o convencional porque é capaz de descontaminar locais onde não é possível alcançar normalmente. Porém, as reações da pele humana à exposição à radiação UV podem ser classificadas como agudas (imediatas) ou crónicas (a longo prazo), desta forma o equipamento possui sensores de movimento para prevenir a exposição acidental de pessoas. Description of the invention [025] The proposed solution consists of a robotic device that uses UV-C lighting and forced ozone generator. The ozone generator constantly emits to the environment, through forced ventilation, carrying ozone to all places where it will pass with the equipment. In the absence of people, sites can be disinfected in a few minutes using UV-C light within a coverage radius of 3.5 m. During the time the UV-C lamps are on, the ozone generator is off. Worldwide, it has been proven that the efficiency of UV-C light and ozone is very high compared to traditional cleaning methods. UV-C decontamination is a clean and effective method compared to the conventional one because it is capable of decontaminating places where it is not normally possible to reach. However, human skin reactions to UV radiation exposure can be classified as acute (immediate) or chronic (long term), so the equipment has motion sensors to prevent accidental exposure to people.
[026] O acionamento da luz UV-C no dispositivo ora proposto é remoto, permitindo que o operador se encontre a uma distância segura. Caso alguém entre no local quando o equipamento estiver operando, sensores de movimento desligam automaticamente as lâmpadas. [026] The activation of UV-C light in the device proposed herein is remote, allowing the operator to be at a safe distance. If someone enters the place when the equipment is operating, motion sensors automatically turn off the lamps.
[027] Levando em conta que o sistema proposto utiliza UV-C como principal princípio de desinfecção, mas também ozônio como método complementar, a solução proposta torna o processo mais rápido e eficiente comparado com as soluções analisadas, já que pode ser usado de forma contínua, mesmo com a presença de pessoas ou animais próximas ao dispositivo. [027] Taking into account that the proposed system uses UV-C as the main disinfection principle, but also ozone as a complementary method, the proposed solution makes the process faster and more efficient compared to the analyzed solutions, as it can be used so continuous, even with the presence of people or animals near the device.
[028] A presente invenção, assim, consiste em um dispositivo robótico constituído por uma base móvel motorizada por atuadores elétricos, conjunto de baterias, estação para carregamento das baterias, conjunto de lâmpadas UV-C montadas sobre uma torre vertical retrátil, um segundo conjunto de lâmpadas UV-C montadas sobre um suporte horizontal retrátil, gerador de ozônio com sistema de ar forçado, sensoriamento para monitoramento da presença de pessoas ou animais nas proximidades do dispositivo, sensoriamento para mapeamento do ambiente e planejamento das rotas, sistema de comunicação sem fio para comunicação com um dispositivo móvel e com uma plataforma Online para controle, supervisão e gestão das atividades. [029] A base móbil constitui-se por rodas com atuadores elétricos e sensores de distância para o mapeamento do ambiente e processador embarcado com software de inteligência artificial (IA) que permite traçar rotas e trajetórias eficientes. Conforme as decisões são tomadas, o processador guia a base mediante os atuadores elétricos. Os sensores são utilizados constantemente pelo software para um constante planejamento da rota e para evitar colisão com os objetos ou pessoas presentes no ambiente. A base possui também o hardware de comunicação sem fio para conectar o robô com a plataforma online. Lâmpadas UV-C fixas na parte inferior do chassi e apontando para o piso permitem a desinfeção do mesmo enquanto a base se movimenta. [028] The present invention, therefore, consists of a robotic device consisting of a mobile base motorized by electric actuators, battery set, battery charging station, set of UV-C lamps mounted on a retractable vertical tower, a second set UV-C lamps mounted on a retractable horizontal support, ozone generator with forced air system, sensing for monitoring the presence of people or animals in the vicinity of the device, sensing for environmental mapping and route planning, wireless communication system for communication with a mobile device and with an Online platform for control, supervision and management of activities. [029] The mobile base is constituted by wheels with electric actuators and distance sensors for the mapping of the environment and embedded processor with artificial intelligence (AI) software that allows to trace routes and efficient trajectories. As decisions are made, the processor guides the base through the electrical actuators. Sensors are constantly used by the software for constant route planning and to avoid collision with objects or people present in the environment. The base also has the wireless communication hardware to connect the robot with the online platform. UV-C lamps fixed to the underside of the chassis and pointing to the floor allow for disinfection of the chassis while the base moves.
[030] A velocidade de movimentação do dispositivo robótico está limitada ao tempo necessário para atingir a dose de energia certa sobre as superfícies presentes. Esta velocidade depende da irradiação presente nas lâmpadas, mas também da distância entre o robô e as superfícies. Quanto mais distantes as superfícies, menor a velocidade. Isto se deve a variação da irradiância por área conforme a distância com a fonte de UV-C. Esta variação é inversamente proporcional ao quadrado desta distância. Da mesma forma, a velocidade de avanço do robô será afetada. Por este motivo, as trajetórias traçadas pelo software visam reduzir estas distâncias para aumentar a velocidade e minimizar o tempo necessário para desinfectar a ambiente. O controle da velocidade em função da trajetória traçada e mapeamento dos objetos presentes na sala garantem a correta dose de energia em todas as superfícies. [030] The speed of movement of the robotic device is limited to the time needed to achieve the right dose of energy on the surfaces present. This speed depends on the radiation present in the lamps, but also on the distance between the robot and the surfaces. The farther the surfaces, the slower the speed. This is due to the variation in irradiance per area according to the distance with the UV-C source. This variation is inversely proportional to the square of this distance. Likewise, the robot's forward speed will be affected. For this reason, the trajectories traced by the software aim to reduce these distances to increase speed and minimize the time needed to disinfect the environment. Controlling the speed as a function of the traced trajectory and mapping the objects present in the room guarantee the correct dose of energy on all surfaces.
[031] O gerador de ozônio encontra-se no interior da base. Este dispositivo, controlado pelo software de IA, é acionado a todo momento quando não for possível utilizar as lâmpadas de UV-C. Um sistema de ar sem hélices força o ozônio para o ambiente. O gerador é regulado de forma a manter o nível de ozônio abaixo do percentual permitido. [031] The ozone generator is located inside the base. This device, controlled by the AI software, is activated at all times when it is not possible to use the UV-C lamps. A propellerless air system forces ozone into the environment. The generator is regulated to keep the ozone level below the allowable percentage.
[032] O corpo do robô consiste em uma torre telescópica que possui um conjunto de lâmpadas posicionadas no sentido vertical e distribuídas 360 graus ao redor do robô. As lâmpadas se encontram sempre ligadas para manter sua potência de irradiação nominal e são expostas ao meio quando o sistema de sensoriamento verifica a ausência de pessoas ou animais no ambiente. [033] A torre telescópica esconde no seu interior parte do conjunto de lâmpadas, enquanto outras são ocultas mediante cortinas plásticas com filtro UV. Na presença de pessoas ou animais, as lâmpadas são instantaneamente desligadas e escondidas, seja mediante a contração da torre, seja pela cortina UV. Uma vez contidas, as lâmpadas são novamente ligadas para manter seu aquecimento nominal. Durante este tempo, o gerador de ozônio é ligado, auxiliando na desinfecção do ambiente. Quando o robô identifica a ausência de pessoas ou animais mediante seu sensoriamento, as lâmpadas são novamente expostas ao ambiente. [034] O suporte lateral encontra-se fixo ao corpo em ambos os lados do robô (esquerdo e direito) e possuem servo atuadores que regulam sua altura e retrair, dependendo do espaço disponível no ambiente. Lâmpadas UV-C são fixas sobre este suporte, tanto na parte superior quanto na inferior, direcionando a radiação UV-C para cima e para baixo. Sensores de distância distribuídos ao longo do suporte permitem não somente medir a distância do dispositivo aos objetos presentes, regulando sua altura de modo de aproximar as lâmpadas da superfície evitando colisão, mas também regular a velocidade de avanço do robô, garantindo a correta dose de energia em todas as superfícies presentes. [032] The robot body consists of a telescopic tower that has a set of lamps positioned vertically and distributed 360 degrees around the robot. The lamps are always on to maintain their nominal radiating power and are exposed to the environment when the sensing system checks the absence of people or animals in the environment. [033] The telescopic tower hides part of the set of lamps inside, while others are hidden by plastic curtains with UV filter. In the presence of people or animals, the lamps are instantly switched off and hidden, either by contracting the tower or by the UV curtain. Once contained, the lamps are turned back on to maintain their rated heat. During this time, the ozone generator is turned on, helping to disinfect the environment. When the robot identifies the absence of people or animals through its sensing, the lamps are again exposed to the environment. [034] The side support is fixed to the body on both sides of the robot (left and right) and have servo actuators that regulate its height and retract, depending on the space available in the environment. UV-C lamps are fixed on this support, both at the top and at the bottom, directing UV-C radiation up and down. Distance sensors distributed along the support allow not only to measure the distance of the device to objects present, regulating their height in order to bring the lamps closer to the surface, avoiding collision, but also to regulate the robot's advance speed, ensuring the correct dose of energy on all surfaces present.
[035] O planejamento da trajetória dependerá também do nível da bateria, fazendo com que o robô possa atender a maior quantidade de espaço até a estação de carga. Estas estações de carga podem ser mais de uma e deverão estar mapeadas na plataforma de gerenciamento. [035] The trajectory planning will also depend on the battery level, making the robot can cover the largest amount of space until the charging station. These charging stations can be more than one and must be mapped on the management platform.
[036] Sensores RFID poderão ser utilizados para indicar setores e inclusive pontos críticos onde seja necessário maior concentração de UV-C ou ozônio devido a periculosidade. O robô poderá ser configurado para que, quando detectado tal ponto pelo robô, sua velocidade ou distância seja alterada para intensificar seu poder de desinfecção. Desta forma, dispositivos ou objetos portáteis ou móveis, presentes no ambiente, que precisem de atenção na sua desinfecção, conforme normas de higiene, poderão ser tagueados para que, quando detectados pelo robô, recebam maiores doces de UV-C ou ozônio. [036] RFID sensors can be used to indicate sectors and even critical points where a higher concentration of UV-C or ozone is needed due to danger. The robot can be configured so that, when such point is detected by the robot, its speed or distance is changed to intensify its disinfection power. In this way, portable or mobile devices or objects, present in the environment, that need attention in their disinfection, according to hygiene standards, may be tagged so that, when detected by the robot, they receive larger UV-C or ozone sweets.
[037] Sensores de presença e detectores de movimento óticos encontram-se presentes no topo da torre e são utilizados por um circuito de segurança eletrónico, independente do sistema de IA do robô, para controlar o acionamento das lâmpadas no correto momento. [037] Presence sensors and optical motion detectors are present at the top of the tower and are used by an electronic security circuit, independent of the robot's AI system, to control the activation of the lamps at the right moment.
[038] Uma câmera e um sistema de áudio, alocados no topo da torre, permitem teleguiar o robô quando um operador deseja controlar o dispositivo de forma remota. Seu acesso é feito via web, acessando a plataforma através de um aplicativo. O mesmo sistema de áudio em conjunto com a câmera serve ao operador para se comunicar com as pessoas presentes na sala de forma remota. Em ambientes de alto risco de contaminação, esta comunicação permite estabelecer um diálogo com pacientes ou pessoas infectadas, evitando a exposição do operador. [038] A camera and an audio system, located at the top of the tower, allow to teleguide the robot when an operator wants to control the device remotely. Its access is via the web, accessing the platform through an application. The same audio system together with the camera serves the operator to communicate with people present in the room remotely. In environments with a high risk of contamination, this communication allows establishing a dialogue with patients or infected people, avoiding operator exposure.
[039] Um botão de emergência encontra-se visível na base do robô. Em caso de segurança, quando acionado o botão, o robô completo é desligado. [039] An emergency button is visible on the base of the robot. In case of safety, when the button is pressed, the complete robot is turned off.
[040] Todas as informações, como imagens, áudios e vídeos, posição, rotas traçadas, trajetórias percorridas, históricos de desinfecção, tempo de operação, vida útil das lâmpadas e previsão para conclusão do serviço, podem ser acessadas no aplicativo e na plataforma de forma remota pelos responsáveis do serviço e por toda pessoa autorizada para acompanhar o processo Online. [040] All information, such as images, audio and videos, position, traced routes, trajectories taken, disinfection history, operating time, lamp life and forecast for completion of the service, can be accessed in the application and on the platform of remotely by those responsible for the service and by any person authorized to monitor the process Online.
[041] Considerando o descritivo aqui exposto, pode-se destacar a presente invenção como a única solução a combater a proliferação de vírus e bactérias presentes em ambientes, combinando UV-C e ozônio para desinfecção de todo tipo de superfície, mesmo na presença de pessoas ou animais nas proximidades de forma autónoma, eficiente e com a possibilidade de monitorar e gerenciar o processo mediante a conectividade. [041] Considering the description presented here, the present invention can be highlighted as the only solution to combat the proliferation of viruses and bacteria present in environments, combining UV-C and ozone for disinfection of all types of surfaces, even in the presence of people or animals in the vicinity autonomously, efficiently and with the possibility of monitoring and managing the process through connectivity.
