| 目前大气环境传感器的测试和标定主要依赖于人工手动操作完成，测试和标定效率较低，结果准确率较差。为解决该问题，在分析大气环境传感器工作原理的基础上，搭建了一套由真空泵电机、气压控制器、高低温箱、金属密封腔、标准数字温度计、工控机、待标定大气环境传感器等部分组成的大气环境传感器硬件测试平台，并设计了大气环境自动化软件测试系统，通过工控机控制标准环境，对标准环境参数进行周期采样，自动判定稳态并记录标定所需参数，从而拟合出标定曲线。对待标定温度和压力传感器进行自动化标定测试，结果显示：温度标定的拟合相关系数为0.994 5，重复性误差为0.087%；压力标定的拟合相关系数为0.996，重复性误差为0.046%，验证了测试系统的可行性。此研究成果为大气环境传感器快速部署应用提供了有力支撑，对于推动自动化技术在大气环境参数测量领域中的应用具有重要意义。 |

| Currently, the testing and calibration of atmospheric environmental sensors heavily rely on manual operations, resulting in low efficiency and poor accuracy. To address this issue, the working principles of atmospheric environmental sensors was analyzed. Based on this, a hardware testing platform for atmospheric environmental sensors was established. It consists of vacuum pump motor, pressure controller, high and low?temperature chambers, metallic sealed chamber, standard digital thermometer, industrial computer, and the atmospheric environmental sensors to be calibrated. Additionally, an automated software testing system for atmospheric environmental conditions was designed. Controlled by an industrial computer, this system periodically samples standard environmental parameters, automatically determines stability, and records calibration parameters to fit calibration curves. Automated calibration tests were performed on temperature and pressure sensors, yielding fitting correlation coefficients of 0.994 5 and 0.996, with repeatability errors of 0.087% and 0.046%, respectively. The results validate the feasibility of the testing system. This research provides robust support for the rapid deployment of atmospheric environmental sensors and holds significant implications for advancing the application of automation technology in the measurement of atmospheric environmental parameters. |
