Système d'acquisition et de gestion de données
Module d’acquisition et de gestion des données (logger & routeur) gérant tous les paramètres : analyseurs de gaz, contrôleurs de poussières, capteurs météorologiques et de température…
Le DAHS e-SAM assure l’accès et le contrôle à distance et bidirectionnel des analyseurs et du SGE via une interface WEB. De plus, ces données peuvent être transmises automatiquement et sans fil à un serveur central, équipé de la suite logicielle XR®, capable de gérer en réseau des milliers de stations de mesure de la qualité de l’air dans une ville, une agglomération ou une région.

-
- Acquisition of instantaneous measurements at a configurable frequency ranging from 5 seconds to 24 hours
- Management of the metrological context: analysers’ parameters and internal failures, technical measurements, external signals (door opened, flow, etc.)
- Controls of lower and higher validity limits, sensitivity threshold, immobility, slope and follow-up of peak episodes
Automatic Validation
-
- Automatic validation of the data with the XR software
- Association of a quality code with each value
- Evaluation of quality indicators for each data value: min, max, standard deviation, number
of over-thresholds, availability ratio - Prevalidation of the data according of the metrological context
Calibration
- Automatic management of calibration sessions: 5 span points
- Ability to adapt the linearization parameters according to calibration results
- Control of absolute, relative drifts, drifts between span points, standard deviation drifts
- Storage of all the information related to the calibration
