Mountain forest soil is an important source of global greenhouse gas emissions, including carbon dioxide (CO2), methane (CH4) and nitrogen oxide (N2O), but the current research on the impact of greenhouse gas emissions from mountain forest soil on the climate is very scarce. This article will focus on methane emissions from mountain forest soils for testing, and introduces a near-infrared spectroscopy on-line inspection, analysis and measurement method for greenhouse gases in mountain forest soils. In this paper, a photoelectric detection system is designed. Based on the STM32F103VB motherboard as the hardware foundation and wireless remote communication technology, a set of mountain forest soil greenhouse gas concentration detection system is developed to achieve online monitoring of mountain forest soil greenhouse gas emissions. The difficulty of this paper is mainly due to the low signal-to-noise signal of greenhouse gases in mountain forest soil. It is difficult to capture the signal. In order to improve performance and cost considerations, this paper uses a differential absorption detection method. The experimental results in this paper show that the full-scale accuracy is 0.6% FS, the system response time is less than 16s, and the relative standard deviation is 1.41%. It has good repeatability and stability, which proves that the system meets the design requirements. At the end of this paper, a brief analysis of the source of the system error is also provided, which provides a direction for further improving the accuracy of the system.
