Abstract

The invention discloses a method and system for testing parameters of a gas-sensitive element. The method comprises the following steps of: simulating a working environment of the gas-sensitive element, and outputting an analogue voltage signal obtained through conversion from gas information in a sensing environment; carrying out analogue-digital conversion on the analogue voltage signal so as to convert the analogue voltage signal into a digital signal; analyzing and calculating the digital signal to obtain test parameters of the gas-sensitive element; and dynamically displaying the test parameters of the gas-sensitive element in text and graph manners. According to the method or system for testing the parameters of the gas-sensitive element, the parameters of the gas-sensitive element can be auxiliarily tested in combination with a computer, so that the complicated operation and calculation processing can be changed into intelligent processing through the computer, therefore the development and production efficiency of the gas-sensitive element is improved, and the manpower and material costs are decreased in the test process.

Description

technical field [0001] The invention relates to the testing field, and more specifically, relates to a method and a system for testing gas sensor parameters. Background technique [0002] The gas sensor is a component that detects specific gases. Its main applications include: carbon monoxide gas detection, gas gas detection, gas detection, Freon detection, ethanol detection in exhaled breath, and human oral bad breath detection. It will The information related to the gas type and its concentration is converted into electrical signals, and the information related to the existence of the gas to be measured in the environment can be obtained according to the strength of these electrical signals, so that detection, monitoring and alarm can be carried out; The circuit and computer form an automatic detection, control and alarm system. Therefore, parameter testing such as the sensitivity of the gas sensor is very important to the quality of the gas sensor. [0003] At present, i...
