地面风传感器智能防冻装置设计与应用检验

我国大部分地区寒冷季节，地面自动气象站风传感器容易冻结，影响观测数据质量，尤其偏远无人值守的区域站，维护保养困难很大，影响时间长.为解决这一问题，提出了一种风传感器防冻结装置的技术思路，从智能防冻装置的结构、功能模块以及智能加热控制等方面开展设计试验.结合外场一次冻雨天气过程的试验，采用CIMISS数据应用检验.结果表明，风传感器防冻装置是冬季保证风要素观测数据完整性连续性的重要措施，对气象站和风力发电场地面风观测站的风传感器的防冻具有广泛应用价值.

Design and application test of intelligent anti-freezing device for surface wind sensor

During the cold season in most regions of China， the wind sensors of automatic weather stations on the ground are easy to freeze， which affects the quality of observation data. Especially for remote and unguarded regional stations， the maintenance is difficult and the impact time is long. In order to solve this problem， a technical idea of wind sensor anti-freezing device was put forward. The design tests were carried out from the aspects of the structure， function module and intelligent heating control of the intelligent anti-freezing device. Combined with a freezing rain weather process test in the field， CIMISS data is applied to test. The results show that the wind sensor antifreeze device is an important measure to ensure the integrity and continuity of the wind observation data in winter， and has wide application value for the anti-freeze of the wind sensor in the weather station and the ground wind observation station of the wind power plant.
