Implementation of Power Efficient Smart Helmet System for Road Safety and Rider’s Convenience using Pico Board

According to the Ministry of Road Transport and Highways' 2021 data, India has reported a total of 4,12,432 road accidents, resulting in 1,53,972 deaths and 3,84,448 injuries. Non-wearing of helmets has affected 1,40,356 persons, with 46,593 deaths and 93,763 injuries. Over-speeding has affected 2,95,522 persons, with 1,07,236 deaths and 2,80,285 injuries. Drunken driving or consumption of alcohol and drugs has affected 10,823 persons, with 3,314 deaths and 7,509 injuries. From this it is evident that a Smart system must be developed to reduce the accident count. The system proposed will able to control the engine based on alcohol consumption status and rider worn the helmet or not. It will monitor the speed continuously and alert the rider regarding over speeding by activating the buzzer. When over speeding count exceeds 5 times in a span of 30 days, SMS is sent to the traffic department using GSM module. Additionally Anti-theft system is also present, which activates the theft buzzer indicating the theft activity. To increase the battery backup, the frequency of the Raspberry Pi Pico microcontroller was reduced to 25MHz from the default frequency of 125MHz. Thus, the overall system was made power efficient and convenient to riders.
