摘　　要：人工影响天气业务在防灾减灾工作中越来越受到重视,并且技术也愈加完善。但是人工降雨一般是以飞机播撒催化剂的方式实现增雨、降雨。人工降雨对气象条件及空气质量有前提条件,对机上指挥人员也有危险性。所以,利用无人机实现自动播撒,自动观测,可以很好地解决安全性的问题。该文主要研究基于无人机的气象数据采集系统的设计,设计无人机气象数据采集的硬件和程序。温度和湿度传感器、气压传感器和HGPS传感器分别用于传输观测数据。传输的数据从控制器写入,进入SD卡然后存储,通过无线数据传输模块,发送到地面主处理计算机进行实时显示。该文采用QT编程语言设计气象数据采集系统的上位机,并对无人机气象数据采集系统进行仿真和测试。测试结果表明,该文设计的系统的气压数据采集与实际值的最大差值小于0.4,采集误差小,满足日常使用的需要。Weather modification is get more and more attention in disaster prevention and mitigation, and the technology is becoming more perfect. However, artificial rainfall is generally realized by seeding catalyst by aircraft to increase rainfall.The artificial rain enhancement operation has preconditions for meteorological conditions and air quality, which is dangerous to the commander on board. Therefore, using unmanned aerial vehicles can be used to realize automatic seeding and automatic observation, the problem of safety will be well solved. This paper mainly studies the design of meteorological data acquisition system based on UAV, designs the hardware and program of UAV meteorological data acquisition. The temperature and humidity sensor, the air pressure sensor and the HGPS sensor are respectively used to transmit observation data. The transmitted data is written from the controller, entered into the SD card and then stored, and sent to the ground main processing computer for real-time display through the wireless data transmission module. The upper computer of meteorological data acquisition system is designed by QT programming language, the weather data acquisition system of UAV is simulated and tested. The test results show that the maximum difference between the air pressure data acquisition and the actual value of the system designed in this paper is less than 0.4, and the acquisition error is small, which meets the needs of daily use.
