MUMBAI, India, Sept. 14 -- Intellectual Property India has published a patent application (202641108160 A) filed by Pragati Engineering College on September 09, 2026, for Ai Sea Condition Alert Band For Artisanal Fishermen.
Inventors include Mr. M. V. Rajesh; Mr. Srikanth Kosaraju; Mr. Kondapalli V V Subba Rao; and Mr. Sayantan Kar.
The application for the patent was published on September 11, 2026, under issue no. 37/2026.
Abstract: FIGURE OF ABSTRACT AI SEA CONDITION ALERT BAND FOR ARTISANAL FISHERMEN India has over 3 million artisanal fishermen operating along 7,500 kilometres of coastline, with 7,373 non-motorised country boats in Tamil Nadu alone. These fishermen venture 30 kilometres offshore without VHF radio, satellite phone, or personal alert devices. During Cyclone Ockhi (2017), 347 fishermen from Tamil Nadu and Kerala died because IMD warnings never reached individual boats at sea. The PreventionWeb report (2021) confirmed this last-mile gap: IMD warnings are in English, radio broadcasts are irregular, and fishermen prefer voice alerts but have no personal device. In 2025, Cyclone Ditwah struck the same coast, and the gap remained unaddressed. The present invention provides a two-unit LoRa-based AI sea condition alert system designed specifically for artisanal fishermen. The Shore Station at harbour comprises a Raspberry Pi 4 with Random Forest classifier trained on 5 years of IMD historical data (2019–2024) for Tamil Nadu coast stations, an LSTM pressure trend model for 6-hour pre-emptive storm prediction, local sensors including anemometer, wind vane, BMP388 barometric pressure, DHT22 humidity, and rain sensor, a LoRa SX1276 broadcaster at 433MHz with 5dBi antenna, and a 20W solar power system. The Fisherman Wristband contains an nRF52840 microcontroller, LoRa SX1276 receiver, WS2812B RGB LED ring, coin vibration motor, and 95dB waterproof piezo buzzer, powered by 1000mAh LiPo battery with 72-hour standby and IP68 waterproof rating to 30 metres depth. The shore station fetches IMD API data and local sensor readings every 10 minutes, classifies sea conditions into SAFE, CAUTION, and DANGER using the Random Forest model with hysteresis, and broadcasts 16-byte LoRa packets. The wristband receives packets, decodes alert levels, and outputs LED colour (green safe, amber caution, red danger), vibration pattern (1 pulse safe, 3 pulses caution, continuous danger), and buzzer (3 beeps caution, continuous danger)—requiring no literacy, no smartphone, and no SIM card. The wristband operates beyond mobile network coverage, costs Rs. 1,800 per unit, and is scalable under PM Matsya Sampada Yojana. The system addresses the documented last-mile warning gap, reducing preventable deaths and building climate resilience for India's fishing communities.
