Scientific Description

From the past decades the monitoring of civil engineering structure became a major field of research and development process in the domains of modelling and integrated instrumentation. This increasing of interest can be attributed in part to the need of controlling the aging of such structures and on the other hand to the need to optimize maintenance costs. From this standpoint the project Cloud2SM (inria ADT) has been launched to develop a robust information system able to assess the long term monitoring of civil engineering structures as well as interfacing various sensors and data. The specificity of such architecture is to be based on the notion of data processing through physical or statistical models. Thus the data processing, whether material or mathematical, can be seen here as a resource of the main architecture. The project can be divided in various items:

• The sensors and their measurement process: Those items provide data to the main architecture and can embed storage or computational resources. Dependent of onboard capacity and the amount of data generated it can be distinguished heavy and light sensors.

• The storage resources: Based on the cloud concept this resource can store at least two types of data, raw data and processed ones.

• The computational resources: This item includes embedded “pseudo real time” resources as the dedicated computer cluster or computational resources.

• The models: Used for the conversion of raw data to meaningful data. Those types of resources inform the system of their needs they can be seen as independents blocks of the system.

• The user interface: This item can be divided in various HMI to assess maintaining operation on the sensors or pop-up some information to the user.

• The demonstrators: The structures themselves.

Beside those objective, the I4S ADT campaign has allowed the development of the first block of the architecture: the data acquisition system. Called Cloud2IR, this prototype implementation of generic sensor interface has been specialized for the long term thermal monitoring of civil engineering structure and opened the way to the development of a whole ecosystem of sensors

Cloud2IR

Cloud 2IR is a software dedicated to the structural health monitoring of civil engineering structures thanks to long term thermal imaging. Its particularity lies in the fact that it is based on a generic approach of the acquisition system concept and the format of the data. That allow it to apply to other types of sensor.
