Single-point calibration differential compensation method for methane gas detector

Abstract

The invention discloses a single-point calibration differential compensation method for a methane gas detector, relates to the technical field of equipment calibration and data processing, and solves the problems that a multi-point calibration method wastes standard gas, manpower and time, and the production cost of the gas detector is increased. The method is composed of a single-point calibration differential compensation method, a single-point calibration calculation process and a differential compensation algorithm process. Comprising the following steps: starting a gas detector, and calibrating the gas detector; methane gas is introduced into the gas detector, and related parameter values are calculated; performing graphical display and differential compensation correction on the obtained related parameter values; calculating a methane concentration value in the environment to be detected according to the graph; the gas detector is calibrated by using an algorithm based on full-scale single-point calibration, and the concentration value of the methane gas in the environment to be detected is detected, so that the stability and reliability of the methane gas detector are improved, the production cost of the methane gas detector is reduced, and the market popularization and application of the methane gas detector are accelerated.
