Autonomous Smart Drone Solution for Monitoring of Reservoirs

With a small operational carbon footprint, ST Engineering's DroNet is an electrically powered network of drones that are operated Beyond Visual Line of Sight (BVLOS) from a command hub. BVLOS means the operation of drones at distances outside the normal visible range of the pilot. The command hub uses automated procedures to enable a small team to deploy multiple drones concurrently. The drones can be launched and recovered autonomously from drone stations at designated sites without the need for an on-site support crew.

The DroNet's Video Analytics module employs Deep Neural Network models that are trained to detect the presence of vessels and aquatic plants in the reservoirs. Drones are flown to capture aerial imageries of the reservoirs to count the vessels in the reservoirs and to classify whether the aquatic plants are near or under water surface. The monitoring would otherwise require the efforts of many boatmen to patrol the reservoirs using diesel-powered boats.

Hyperspectral sensors are integrated onto the drones, tuned and regressed to measure the level of chlorophyll-a and turbidity remotely. In addition to offering wider coverage within a shorter time frame, the measurement capability also provides near real-time water quality data, eliminating the need for laboratory tests on water samples.

A web-based Viewing Platform and mobile-based Alert Notification System were developed to share real-time data and notifications with users, improving their operational response time.
