Investigate past, real-time and expected future performance for each asset using an embedded hydraulic model that is continuously updated with boundary conditions from sensors. The user is no longer limited by the number and location of sensors, being able to readily monitor several parameters at every point in the system.
Allows to user to select the Background map to be displayed: Aerial, Hybrid, Street, None
The user can control the elements that are shown on the map, such as:
The default map view is an integrated view of the system, where hydraulic model elements are displayed together with the network sensors. When the model is first opened, it displays pipes colored by flow and nodes by pressure while the background is aerial view. The results correspond to the model run based on the most recent boundary conditions (e.g. pump status, tank levels) that have been imported from the SCADA system.
The user can zoom in or zoom out using the scroll button of the mouse or using the "zoom" button located on the top right corner. It is also possible to navigate to any part of the network by moving the mouse while clicking at the same time in the scroll button (or by clicking in the "pan view" button located on the top right corner). Other options include the zoom extents view ("Fit view") and the button to select any element on the map in order to see the respective properties and results.
When clicking in any element on the map a table with the main properties and results of the selected element will pop up, together with a graph below.
For any hydraulic element selected (any pipe, node, pump, tank, reservoir, PRV or TCV) the graph view will display the historical results, real time results and forecasts for the variables available, based on the hydraulic model calculations. The historical and forecast period duration is defined at the administration level, in the Numerical Models configuration page. The hydraulic model (WaterGEMS model) can be uploaded in the administration tab (Numerical Models configuration page) and will automatically run at a given frequency, that is also user defined. SCADA or other telemetry data will be used to set the initial conditions for the model calculations.
Figure 1. Map view results and graph view results for a hydraulic model element.
When clicking in any sensor on the map, the user will have access, in a graph view, to historical results, real time results and forecasts for the variables available. The user can see in the same graph real sensor data, that is re-sampled, (represented by black, red or orange circles) together with the pattern confidence bands, that correspond to the expected behavior (represented by grey bands). These bands are computed based on sensors historical raw data, using advanced data analytics (statistical analysis together with machine learning algorithms). The sensor graphs are the same available on the Network Monitoring tab. For more details, please go to the Sensor Details page.
Figure 2. Map view results and graph view results for a sensor element.
Below the map (or below the graph view when any element in the map is selected) there is a time slide range bar that allows the user to navigate in the time history. Map results are updated accordingly whenever the user moves the time slide range bar backwards and forward in time. In case any element is selected, the "Map" marker on the graph allows the user to easily identify the time step that is being analyzed. The "Now" marker on the graph represents the local current time of the machine where WaterSight is running, and should match (most of the time) the current time at the water utility.
The user can easily check if sensors data is being successfully used as initial conditions for the model runs. Click in the hydraulic model element which initial conditions were previously configured (the hydraulic model element must have a valid sensor signal associated) and analyze the graph. The green line corresponds to the sensor value from the SCADA (or other telemetry system) while the blue line corresponds to the calculated result from the model. If everything was correctly configured in the original WaterGEMS uploaded model, the initial instant/timestep value of the model run (when the blue line starts) should match the value from the green line. In case there is a gap between the value for the initial timestep of the model run and the sensor data, the user should check the configurations of the uploaded WaterGEMS model. For more details about these configurations, please go to the Numerical Models configuration page.
