A presente patente de invenção tem por objetivo um sistema de controle eletrônico rigoroso de liberação e destravamento de assento de cadeiras numeradas, para uso em estádios, ginásios, teatros, cinemas e similares, com vistas a garantir aos usuários que adquirirem um lugar numerado que este seja liberado apenas para o respectivo comprador, de forma a melhorar a qualidade dos eventos que poderão oferecer assentos numerados que são realmente respeitados.  The purpose of the present invention is a rigorous electronic numbered seat release and unlocking control system for use in stadiums, gyms, theaters, cinemas and the like to ensure that users who purchase a numbered seat enjoy the same. only be released to the respective buyer in order to improve the quality of events that may offer numbered seats that are actually respected.
DESCRIÇÃO DO ESTADO DA TÉCNICA  DESCRIPTION OF TECHNICAL STATE
Já são conhecidos métodos de controle de numeração de cadeira através apenas de sinalização nas fileiras e nas cadeiras, cujo controle é feito por funcionários que procuram orientar o público a buscarem seus respectivos lugares.  Chair numbering control methods are only known by signaling in the rows and chairs, which are controlled by officials who seek to guide the public to search for their respective seats.
Em que pese a larga utilização deste método, alguns inconvenientes podem-lhe ser atribuídos, como por exemplo a falta de respeito de boa parte do público que chega mais cedo em ocupar cadeiras diferentes das que foram adquiridas por serem mais privilegiadas, a falta de recursos dos orientadores para garantir o ■ respeito à numeração das cadeiras, tendo em vista o grande número de pessoas que chegam ao mesmo tempo. Despite the widespread use of this method, some drawbacks can be attributed to it, such as the lack of respect of a good part of the public that arrives earlier in occupying seats different from those acquired because they are more privileged, lack of resources ■ mentors to ensure respect for chair numbering, given the large number of people arriving at the same time.
Outro problema com o método atual é a discussão e princípios de tumultos que o consumidor que adquiriu uma cadeira numerada tem com a pessoa que está ocupando o lugar indevidamente e os seus amigos ao seu lado, sem mencionar que um bom número de pessoas deixa de 'frequentar tais lugares por conta destes inconvenientes causando sérios prejuízos aos organizadores do evento . Another problem with the current method is the discussion and principles of riots that the consumer who has bought a numbered chair has with the person who is taking the seat improperly and his friends by his side, not to mention that a good number of people fail to ' go to such places because of these inconveniences causing serious damage to the event organizers.
A solução que faz o controle através de cartão com código de barras ou cartão magnético e similares possui graves deficiências pois, para atingir a mesma funcionalidade do objeto proposto na presente invenção, este caso necessita que em cada cadeira haja um sistema micro-controlado extremamente caro, com uma leitora de cartão tão caro quanto, cuja dimensão é significativamente grande, sem falar que deve haver um cabo de comunicação para cada cadeira para atualização de informações de sistema .  The solution that controls with bar code card or magnetic card and similar has serious shortcomings because, to achieve the same functionality of the object proposed in the present invention, this case requires that in each chair there is an extremely expensive micro-controlled system. , with a card reader as expensive as its size is significantly large, not to mention that there must be a communication cable for each chair to update system information.
Cumpre notar que, é impraticável pensar que num estádio de futebol por exemplo deva haver uma rede com centenas ou milhares de cabos de comunicação interligando-se, suscetíveis a defeitos, falhas de comunicação durante um evento importante e inoperação em momentos cruciais.  It should be noted that it is impractical to think that in a football stadium for example there should be a network with hundreds or thousands of interconnecting communication cables susceptible to malfunctions, miscommunication during an important event and inoperation at crucial moments.
0 sistema proposto é totalmente independente e imune de comunicação externa, sendo auto-suficiente, de fácil manuseio e a prova de vandalismos. Isso resulta num custo extremamente baixo, o que permite a fácil reposição em caso de qualquer dano ou mau funcionamento. Este aspecto é útil para que a operação do sistema seja contínua e ininterrupta, mesmo em eventos contínuos e com público hostil, que é o caso de estádios.  The proposed system is totally independent and immune from external communication, being self-contained, easy to handle and vandal proof. This results in an extremely low cost which allows easy replacement in case of any damage or malfunction. This aspect is useful for the system operation to be continuous and uninterrupted, even in continuous events and with hostile public, such as stadiums.
Uma leitora de cartões como foi proposto em outras soluções é facilmente inutilizada por vandalismo, por exemplo, com um chiclete no orifício de leitura do cartão, enquanto que o sistema objeto da presente invenção tem como interface apenas um teclado antivandalismo, indiscutivelmente fácil de limpar e recuperar, supervisionado por um pequeno circuito micro-processado, inegavelmente simples, independente de qualquer informação externa. A card reader as proposed in other solutions is easily vandalized by, for example, a gum in the card reading hole, while the system object of the present invention has only one anti-vandalism keyboard, arguably Easy to clean and recover, supervised by a small, undeniably simple micro-circuitry, independent of any outside information.
