本文介绍了一种能够测量气象温度、湿度、气压等大气数据的无线电探空仪的设计与实现。该系统由CPU、微波模块、温度传感器、压力传感器和湿度传感器阵列组成。为了有效解决高海拔环境下湿度传感器因温度低而结露的问题，采用微机电系统（MEMS）技术，研制了一种由4个湿度传感器采集气象湿度和铂电阻加热器组成的电容式湿度传感器。使用纯度为99.999%、直径为0.023 mm的铂电阻丝获得气象温度。采用多传感器数据融合技术对大气数据进行处理。静态和动态实验结果表明，所设计的铂电阻加热湿度传感器能有效解决传感器结露问题，缩短响应时间，提高灵敏度。湿度传感器阵列可以提高测量精度，获得可靠的初始气象湿度数据，而多传感器数据融合技术消除了测量中的不确定性。无线电探空仪能准确地反映气象变化。
This paper describes the design and implementation of a radiosonde which can measure the meteorological temperature, humidity, pressure, and other atmospheric data. The system is composed of a CPU, microwave module, temperature sensor, pressure sensor and humidity sensor array. In order to effectively solve the humidity sensor condensation problem due to the low temperatures in the high altitude environment, a capacitive humidity sensor including four humidity sensors to collect meteorological humidity and a platinum resistance heater was developed using micro-electro-mechanical-system (MEMS) technology. A platinum resistance wire with 99.999% purity and 0.023 mm in diameter was used to obtain the meteorological temperature. A multi-sensor data fusion technique was applied to process the atmospheric data. Static and dynamic experimental results show that the designed humidity sensor with platinum resistance heater can effectively tackle the sensor condensation problem, shorten response times and enhance sensitivity. The humidity sensor array can improve measurement accuracy and obtain a reliable initial meteorological humidity data, while the multi-sensor data fusion technique eliminates the uncertainty in the measurement. The radiosonde can accurately reflect the meteorological changes.
