【摘要】 矿山环境毒害气体的定量实时监测是保障矿山安全开采的重要技术手段，在矿山开采及工业环境中，危险气体如甲烷（CH₄）、一氧化碳（CO）积聚会引发爆炸中毒等事故，通过实时监测气体浓度可以避免危险气体导致的爆炸、中毒事故发生，然而现有的便携式气体分析仪普遍存在监测组分少、仪器体积过大、在井下低压或高压的环境下误差较大的情况，难以大范围应用。基于此研制了一套激光便携式工业环境气体多参数智能测定系统，拟合压力与误差关系公式，通过实验验证该公式能够有效消除环境压力变化对气体传感器精度的影响，将因压力变化导致的测量误差从最大58%降至7%,显著提升了测量精度和稳定性；同时，研发了一套集成数据采集、处理、分析及展示功能的智能监测软件，简化了操作流程，提高了工作效率。设计了轻便坚固的防爆外壳，集成了多组分气体传感器，解决了传统设备体积大、便携性差以及监测组分单一的问题。实验室测试结果表明，该系统在常温常压条件下对CO₂、 CH₄和CO的测量误差分别小于4×10⁴、10⁵和1 ppm,温度和压力测量结果与实际情况高度吻合。误差分析显示，CO₂的均方根误差（RMSE）和平均绝对误差（MAE）均小于0.2, CH₄的MAE和RMSE为0.5和0.61, CO的MAE和RMSE为0.54和0.73,进一步证明了该系统在复杂环境下的高精度与可靠性。该研究成果为煤矿井下及工业环境中的气体监测提供了高精度、便携化的解决方案，显著提升了安全生产水平，降低了环境风险，为煤矿等高危行业保障人员生命安全具有重要意义，同时为环境保护和工业智能化发展提供了有力支持。更多还原

【Abstract】 Quantitative real-time monitoring of toxic gases in the mining environment is an important technical means to ensure safe mining, in the mining and industrial environment, dangerous gases such as methane（CH₄）, carbon monoxide（CO） accumulation will cause explosion poisoning and other accidents, through real-time monitoring of the gas concentration can be avoided by the dangerous gases caused by the explosion, poisoning accidents, however, the existing portable However, the existing portable gas analysers generally have few monitoring components, large instrument volume, and large error under low or high pressure environment in the well, which makes it difficult to be applied in a wide range. Based on this paper, this paper developed a set of laser portable industrial environment gas multi-parameter intelligent determination system, fitting the pressure and error relationship formula, through experiments to verify that the formula can effectively eliminate the impact of environmental pressure changes on the accuracy of the gas sensor, the measurement error due to pressure changes from the maximum of 58% down to 7%, which significantly improves the accuracy and stability of the measurement; at the same time, the development of a set of integrated data At the same time, it has developed a set of intelligent monitoring software with integrated data acquisition, processing, analysis and display functions, which simplifies the operation process and improves the working efficiency. A lightweight and sturdy explosion-proof housing is designed, and a multi-component gas sensor is integrated, solving the problems of large volume, poor portability and single component monitoring of traditional equipment. Laboratory test results show that the measurement errors of the system for CO₂, CH₄ and CO are less than 4×10⁴ ppm, 10⁵ ppm and 1 ppm, respectively, under normal temperature and pressure conditions, and the temperature and pressure measurements are highly consistent with the actual situation. The error analyses show that the root mean square error（RMSE） and mean absolute error（MAE） are less than 0.2 for CO₂, 0.5 and 0.61 for MAE and RMSE for CH₄, and 0.54 and 0.73 for MAE and RMSE for CO, which further proves the high accuracy and reliability of the system in complex environments. The research results provide a high-precision and portable solution for gas monitoring in underground coal mines and industrial environments, which significantly improves the level of production safety and reduces environmental risks, and is of great significance for safeguarding the lives of personnel in high-risk industries such as coal mines, and also provides strong support for environmental protection and industrial intelligent development.更多还原
