Abstract

Patente de Invenção: <B>"CONTROLADOR DE TEMPERATURA DE MúLTIPLOS PONTOS DIGITAL"<D>. A presente invenção refere-se a uma unidade de controle de termostato digital eletrónico compreendendo um elemento de percepção de temperatura linear (1) conectado com um conversor A-D (3), um circuito de correção de sensibilidade e deslocamento (4), comparadores digitais (5, 6), filtros de ruído digitais (7, 8), um trinco de controle (9), um circuito de acionamento e de proteção de saída (10) e uma chave de estado sólido (11) para produzir a saída desejada com a entrada do usuário em forma analógica utilizando um potenciómetro (12) ou em forma digital utilizando uma chave com dados de calibragem e de controle armazenados em uma memória não-volátil e uma unidade de exibição (18) para exibir a temperatura percebida ou estabelecida pelo usuário. A invenção adicionalmente refere-se à aplicação do dito termostato digital eletrónico em um controlador de temperatura de múltiplos pontos para sistemas de refrigeração e de aquecimento utilizando uma pluralidade das ditas unidades de controle de termostato eletrónico (40 até 44) com um circuito lógico, uma unidade de controle central (71), temporizadores do sistema e um circuito de relê de partida para proporcionar funções específicas da aplicação. A implementação também é apresentada na forma de um Circuito Integrado de Aplicação Específica (ASIC) (32) para proporcionar um tamanho e custo reduzidos.
