Abstract: A computerized process for controlling an air purification system comprises a bioreactor in particular, the system may include a photobioreactor for treating urban air, in particular for CO2 removal. The system may be connected to the sanitation network and/or to a (drinking and/or municipal) water supply network. The connection and the drainage system may in particular maintain a fluidic isolation between the two types of networks. The system may optionally be equipped with measurement sensors and/or actuators that make it possible to control the internal activity of the bioreactor. Various control modes of a grid of bioreactors are described. Data on the status of the connected networks (e.g. water, sanitation, cooling, heating networks) contribute to the control of a network of geolocalized bioreactors. The software aspects are described. The supervision of the grid of bioreactors may in particular be carried out remotely via onboard communication devices.

Abstract: Disclosed is a method for detecting anomalies in a distribution network equipped with sensors. The steps are: acquiring for each sensor a time series of physical measurements separated by time intervals; defining time windows each corresponding to a plurality of successive time intervals; extracting operational characteristics of each time series in each time window; forming, for each time window, at least one current vector having for coordinates the operational characteristics, structural data relating to the network and situational characteristics specific to the time window; comparing the current vector with preceding vectors corresponding to preceding time windows and the situational characteristics and structural data of which are similar to those of the current vector; and signalling an anomaly in cases where the current vector is significantly dissimilar to the preceding vectors.

Abstract: A hydraulic model of the network is used that describes the structural data and the laws governing the distributed flows. The model is fed with operational data relative to primary input parameters and, using the model, theoretical values are obtained for primary output parameters. The theoretical values are compared with measured values. In case of a significant deviation, the corresponding primary output parameter becomes a secondary input parameter in an inverse model including new secondary output parameters, which are added relative to the direct model and which correspond to primary input parameters. The secondary output parameters are, by priority, those to which the primary output parameter exhibiting the abnormal value is particularly sensitive. If necessary, the method is implemented iteratively by progressively restricting the number of the secondary output parameters.
