[0073] A model building module is used to obtain the spatial structure data of the organic matter analysis chamber in the target analyzer, determine the ignition parameters of the ignition mechanism in the target analyzer when igniting in the organic matter analysis chamber, and build a control model based on the spatial structure data and the ignition parameters;

[0074] A start control module, used for sensing in real time whether volatile organic matter to be analyzed is input into the organic matter analysis chamber based on the first target sensor, and when volatile organic matter to be analyzed is input into the organic matter analysis chamber, generating a start control instruction based on the control terminal, and controlling the ignition mechanism to start the working procedure according to the start control instruction;

[0075] The ignition state control module is used to detect the target input amount of the volatile organic compound to be analyzed in real time based on the second target sensor. At the same time, the target input amount is input into the control model for analysis, and a dynamic control instruction is generated based on the analysis result based on the control terminal, and the ignition mechanism is controlled to adjust the operating state in real time based on the dynamic control instruction.

[0076] In this embodiment, the target analyzer may be an instrument for analyzing volatile organic compounds, and the volatile organic compounds are ignited and burned in an organic compound analysis chamber, thereby realizing identification and analysis of the volatile organic compounds.

[0077] In this embodiment, the ignition parameters of the ignition mechanism include: ignition rate and ignition amount.

[0078] In this embodiment, the spatial structural data of the organic matter analysis chamber may be structural data characterizing the contour shape of the organic matter analysis chamber.

[0079] In this embodiment, the control model can be used to perform analysis based on the content of volatile organic compounds to be analyzed in the organic analysis chamber, and then output the optimal ignition efficiency and optimal ignition amount of the ignition mechanism under the current content of volatile organic compounds to be analyzed, so as to achieve the optimal combustion efficiency of the volatile organic compounds to be analyzed in the organic analysis chamber, and realize the intelligent automatic ignition of the ignition mechanism.
