The invention discloses an aircraft corrosion environment monitoring method and device and belongs to the field of structure health monitoring. According to the method, a plurality of environment parameters prone to causing corrosion are measured to determine the environment corrosion level, and accordingly, the aircraft structure health condition is evaluated to guide technical attendants to take corresponding measures. The aircraft corrosion environment monitoring device is mainly composed of a master-control micro-control module, a measurement module, a communication module and a power supply module. The device is small in size, low in energy consumption and suitable for being mounted at every position of the aircraft for long-term monitoring. According to the method and the device, existing scheduled maintenance of the aircraft can be changed into maintenance as required, the efficiency is improved, and the cost is reduced.
Description
technical field The invention relates to an aircraft corrosion environment monitoring method and a device for realizing it, and belongs to the technical field of structural health monitoring. Background technique Corrosion of aircraft structure refers to the cumulative chemical loss and damage of components over time through chemical or electrochemical action in the service environment. Its randomness is large, its types are extensive, its influencing factors are numerous and its interaction is strong, so it cannot be completely avoided. The corrosion damage of the aircraft directly affects the remaining life and is related to flight safety. However, in the early stage of corrosion, it is difficult to detect the corrosion site, and when the corrosion initiates, if it is not controlled, it will develop faster and more seriously than other damages. Therefore, it is necessary to actively prevent and control the generation and spread of corrosion. At present, in the field of...
