提在地面气象观测业务中通常采用人工观测的方式来判断结露、结霜现象的发生，人工观测主观性强，观测频次少，工作效率低，不能全面、连续反映结露、结霜过程的特征。本文介绍了一种结露、结霜自动化观测装置，装置工作原理是电容传感器在高湿和低湿情况下电容变化较大，通过测量电容变化引起的频率变化，然后由识别软件来判断结露现象的发生，再结合温度信息以及结冰信息就可以判断结霜现象的发生，从而实现了结露、结霜的自动化观测。通过大量的结露、结霜的对比试验表明露、霜自动化观测装置能够比较准确地识别结露、结霜过程的发生，能够推广到台站业务使用。

In meteorological observation services,artificial methods are usually used to determine the occur-rence of dew and frost phenomena.Manual observation has strong subjectivity,fewer observing times and low efficiency and it can not fully and continuously reflect the characteristics of dew and frost process. This article describes a dew and frost automatic observation device.The device works by detecting changes in capacitance of capacitive sensors in high humidity and low humidity conditions and measuring frequency changes caused by the change in capacitance.Then the recognition software is used to judge occurrence of dew phenomenon and frost phenomenon combined with freezing temperature information and icing informa-tion in order to achieve the dew and frost automatic observation.Through a lot of dew and frost compara-tive tests,we found the automatic observation device can accurately identify the occurrence of dew and frost process and the device can be extended to the practical use.
