Abstract(s)
A ideia da construção de uma câmara automatizada para o teste de detetores de
gases surge no desenvolvimento de um detetor de monóxido de carbono (CO) e gás de
petróleo liquefeito (LPG) na empresa Global Fire Equipment, S.A. (GFE). O projeto
consiste na criação de uma câmara hermética capaz de realizar os testes necessários para
atestar o correto funcionamento de um detetor de gás usado nos sistemas endereçáveis de
deteção de incêndios.
A opção da construção de uma câmara para o teste dos detetores de gases prendese
com o facto de câmaras de teste com as características necessárias serem soluções por
medida e dispendiosas, que encarecem o desenvolvimento do produto.
A Câmara Automatizada Para Teste De Detetores De Gases (CGAS) é constituída
por três partes, a unidade de processamento (computador), a unidade de controlo e a
câmara de teste. A câmara possui vários sensores e atuadores, que serão monitorizados
pela unidade de controlo, equipada com uma central de deteção de incêndios. Por fim esta
unidade é controlada pelo computador através de um ambiente gráfico gerado pelo
software Labview.
The idea of building an automated gas detector test chamber originated in the development of a carbon monoxide (CO) and liquefied petroleum gas (LPG) detector at Global Fire Equipment, S.A. (GFE). The project consists of creating an airtight chamber capable of performing the necessary tests to attest the correct functioning of a gas detector used in Addressable Fire Detection Systems. The option of constructing a chamber for the testing of gas detectors is related with the fact that test chambers with the necessary characteristics are not cost-effective and are customized solutions that make the product development more expensive. The Automated Chamber for Testing Gas Detectors (CGAS) consists of three parts, the processing unit (computer), the control unit and the test chamber. The chamber has several sensors and actuators, which will be monitored by the control unit, equipped with a fire detection panel. Finally, this unit is controlled by the computer through a graphical user interface generated by Labview Software.
