Sensing systems and methods for determining and classifying corrosivity

摘要

A corrosivity associated with each of multiple locations near, on, or within a structure exposed to an environment that can corrode the structure is determined. Each of multiple sensor nodes is mounted at a corresponding one of the locations and measures environmental sensor information using one or more environmental sensors and corrosion sensor information using one or more corrosion sensors. The environmental sensor information is processed to obtain for the sensing node a first atmospheric corrosivity category value in accordance with a corrosivity classification system, and the corrosion sensor information is processed to obtain a second atmospheric corrosivity category value for the sensing node in accordance with the corrosivity classification system. One or more of the first and second atmospheric corrosivity category values is provided for use in determining a corrosion classification value for each of the locations.

1. A method of determining corrosivity associated with a location near, on, or within a structure exposed to an environment that can corrode the structure, where a sensor node is mounted at the location, the sensor node performing steps comprising:
measuring environmental sensor information using one or more environmental sensors and corrosion sensor information using one or more corrosion sensors, where the environmental sensor information includes one or more of measured relative humidity, air temperature, surface temperature and conductivity parameters, and the corrosion sensor information includes a corrosion rate parameter; processing, by a data processor, the environmental sensor information to obtain for the sensing node a first atmospheric corrosivity category value in accordance with a corrosivity classification system; processing, by the data processor, the corrosion sensor information to obtain a second atmospheric corrosivity category value for the sensing node in accordance with the corrosivity classification system; and providing one or more of the first and second atmospheric corrosivity category values for use in determining a corrosion classification value for the location.
