关于振筒气压仪替代方案的设计

Ideas in Replacement Scheme for Vibrating Cylinder Barometer

摘要: 本文介绍乌鲁木齐机场振筒气压仪使用情况，分析2015年~2019年间故障情况，提出维萨拉气压计PTB330+气象面板显示器WID513替代振筒气压仪做备份气压设备的方案，避免备份气压误差数据可能造成的不安全影响，同时可在自观气压计PTB330故障、送检期间作为备份传感器，有力地保障民航飞行安全，供气象设备维护同行参考。

Abstract: This paper introduces the application of Vibrating cylinder barometer in Urumqi airport and analyzes the malfunction during the period from 2015 to 2019. Additionally, project PTB330+WID513 was proposed to replace the Vibrating cylinder barometer for backup pneumatic equipment to avoid unsafe effects incurred by the uncertainty of data measurements in backup pressure. Meanwhile, at a time when encountering AWOS PTB330 malfunction or inspection, this project could still be used as a backup sensor, which effectively ensures the flight safety of civil aviation and provides reference for the meteorological equipment maintenance.
