Description

The CEOS project delivers a reliable and secure system of inspections of pieces of works using professional mini-drone for Operators of Vital Importance coupled with their Geographical Information System. These inspections are carried out automatically at a lower cost than current solutions employing helicopters or off-road vehicles.

Logo of CEOSValidation of the solution, in cooperation with the DGAC, is carried out on private test areas and then on the sites of end-users partners: ENEDIS (medium voltage overhead powerlines), EDF (penstock pipes in mountain areas) and airports of Lyon and Caen-Carpiquet (fences surrounding the airport).

The CEOS system is composed of a mini drone and its ground station provided by the Alerion SME. Several software applications are developed, adapted and integrated on the drone, within an innovative multi-criticality architecture and mixed criticality using multi-core hardware and a hypervisor certifiable on the shelf: detection of anomalies by image analysis by the ADCIS SME, resilient and secure communications from the drone to the GIS by THALES and the ESIEE, control by the RTaW SME and 3D corridor navigation by the University of Lorraine. The architecture developed by INRIA and ESIEE guarantees the real-time operation of the most critical functions, in this case the control and navigation of the drone, to the detriment of the other functions. This is a compromise between too expensive certification and oversized hardware.

Project name

Céos (French name for Coeus or Koios) is a titan and giant of the Greek mythology, god of intelligence (“who knows / thinks”). He also defines the line around which constellations turn. Here, CEOS refers to the artificial intelligence associated with the drone to inspect and move.

CEOS solution advantages

The project is in an experimental phase in the field for the various use cases for detecting defaults or usury:

The goal of the project is to carry out, using a drone, exhaustive, and automatic surveillance of all equipment and infrastructure elements.

This project brings an environmental gain because currently the airport fences are inspected by all-terrain vehicle and, in the case of medium voltage lines, surveillance is done in part by helicopter. Using a drone also limits the risks taken by response teams and the costs incurred.

The monitoring of penstocks requires the intervention of rope access technicians and the monitoring of medium voltage lines may require a walking inspection in wooded areas. The drone makes these surveillance tasks over long distances and difficult to access, less tedious.

Generally an exhaustive inspection can be done more regularly and the automation also brings a qualitative gain because the flight plan of the drone is reproducible.
