摘　　要：目的研究腐蚀与环境条件之间的关系,提出一种用于飞机腐蚀环境监测的小型化监测节点的实现方法。方法针对影响腐蚀的4个关键环境参数(温度、相对湿度、湿润时间和氯离子浓度),研究其传感方法并研发选型相应传感器。在此基础上设计基于MSP430处理器的多参数飞机腐蚀环境监测节点。结果通过实验验证了节点中的温湿度传感器、湿润时间传感器和电化学传感器的适用性,能够完成对环境参数的的测量。结论设计的节点满足机载装置小型化、轻量化的要求,可以实现在线的腐蚀环境监测,从而保障飞行安全。Objective To study the relationship between corrosion and environment,a realizing method of the multi-parameter miniaturization monitoring node for aircraft corrosive environments was proposed in this paper. Methods Four key environmental parameters which are the major factors affecting the corrosion were selected： temperature,humidity,time of wetness（ TOW） and chloride ion concentration. And the corresponding sensors were chosen or designed for monitoring.Besides,this paper introduced a miniaturization monitoring node which could realize the measurements of multiple corrosive environmental parameters. The monitoring node was based on the Texas Instruments MSP430micro-controller and included the aforementioned sensors. Results In the end,the verifications showed that the humidity and temperature sensor,the TOW sensor,and the electrochemical sensor were available; the measurements of four parameters could be performed correctly by the node. Conclusion Featuring a small volume and low weight,the node was applicable for on-aircraft corrosion monitoring. And this approach will provide actionable knowledge for aircraft maintainers,such that the aircraft safety could be driven to increased levels.
