基于WSN的机棚温湿度精确监测系统设计

沿海地区的航空装备因高温、高湿和盐雾导致的腐蚀尤为严重,目前对此普遍采用的维护措施缺乏可靠的参考,影响维护效率和装备完好率.构建开放环境中贴近停机位的多点实时温湿度监测系统是实现科学维护的重要基础.通过比较目前机场采用的各种监测网络、分析停机位分布特征以及机场传感器布放的特殊要求,提出基于无线传感器网络(WSN)的温湿度精确监测系统.通过采用NI公司的WSN技术搭建监测网络,实现无线网络与有线网络的无缝连接,实现了对不同气候环境、不同规模机场以及不同形式停机位的全适应,具有能耗低、布线少和软硬件扩展能力强等优点.该系统为机务人员的防潮维护工作提供精确的定量参考,对实现按需维护和保障装备完好率具有重要意义.

Design of hangar temperature and humidity monitoring system based on WSN

High temperature,humidity and salt fog answer for most corrosion on airborne equipments deployed near coastline.Maintenance methods at present time are subjective and inefficient.Constructing distributed Real-time temperature and humidity monitoring system is important for scientific maintenance.After comparing several types of airport monitoring systems,considering distribution of air crafts and special restriction on sensor cable,new monitoring system based on WSN was brought forward.With the assistance of NI-WSN products,the new system could merge wireless and wired network and was applicable to airports with various scale and form under various climatic conditions.It has the advantages of low energy consumption,less wire layout,strong software and hardware expandability.It can provides quantitative reference for accurate moistureproof maintenance work.It has an important significance to achieve the required maintenance and the airborne equipment intact rate.
