(English Abstract) |
A small-sized gas identification system has been fabricated and characterized using an integrated gas sensor array and artificial neural-network. The sensor array consists of four thick-film oxide semiconductor gas sensors whose sensing layers are In₂O₃-Sb₂O_5-Pd-doped SnO₂ Pd-coated layer, La₂O_5-PdCl₂-doped SnO₂, WO₃-doped SnO₂ Pt-coated layer and ThO₂-V₂O_5-PdCl₂-doped SnO₂. The small-sized gas identification instrument is composed of a GMS 81504 containing an internal ROM (4k bytes), a RAM (128 bytes) and four-channel AD converter as MPU, LEDs for displaying alarm conditions for three gases (liquefied petroleum gas: LPG, liquefied natural gas: LNG and carbon monoxide: CO) and interface circuits for them. The instrument has been used to identify alarm conditions for three gases among the real circumstances and the identification has been successfully demonstrated. |
