智能气体识别仪用以识别气体种类，它具有学习识别多种气体的功能。本文介绍了仪器的工作原理、特点及仪器的硬件和软件构成。
Intelligent Gas Recognizer is a new type of portable tester used toidentify a variety of gases.The Intelligent Gas Recognizer developed by the paper's author consists of a hand testing probe and a small size host machine.The Recognizer uses a single chip processor to collect and process the signals of various units in sensor array,and uses the pattern recognition technique to have accomplished a accurate identification to gases.The core of the testing probe consists of 8 semiconductor gassensitive sensors. The host machine consists of a power module, a microprinter,a liquid crystal display screen and a single chip processor circuit.All the software of the Gas Recognizer has been compiled with PLM/96 high level programming language,which has a high service ability.In the end of this paper a operation characteristics of the recognizer and the testing result to 5 kinds of gases has introduced,which indicates that the recognizer has a high testing performance with the developing requirements reached.
