RF Module Based -- Speed Check and Seatbelt Detection System

Motor vehicles have become an essential part of our day to day life. The demand for the vehicles is increasing at uncontrollable rate. The other rate which is also going beyond control is Road Accident. Road Accidents happen in case of Rash Driving, Over-speeding, Breaking Lanes, Ignoring Safety Precautions etc. This happens globally and is one of the major causes of death. In its report, WHO (World Health Organization) claims that in the year of 2010 China and India have registered more than 2 lakhs deaths in road accidents [7]. CDC (Centers for Disease Control and Prevention), in its report, claims that in the year of 2009 India had topped the list of Road Traffic Fatalities followed by China and USA respectively [8]. It also claims that these fatalities happen more with Middle Income Grade and Lower Income Grade people. Another report claims that about 40% of Road Accidents happens either due to over-speeding or negligence in safety precautions [9]. Keeping these facts in the mind, it has been decided to develop a system which cannot just only control the speed of the vehicle but also urges them to fasten their seatbelt. The system will be a combination of Speed Controlling Circuit and Seatbelt Detection Circuit. This system will have to parts 1) Transmitter and 2) Receiver System. Transmitter part will be on the Road Side at Speed Sign Board. The role of the transmitter is to transmit the maximum allowable speed limit of that road to receiver. Receiver part will be on the vehicle embedded with the system. Role of the receiver would be to compare received Speed Limit Data (received from transmitter) with current speed of the vehicle. It will generate a signal in case of over-speeding and after 10 seconds the engine will stop. In addition to this, it also keeps checking whether Driver and/or Co-Driver (if present) wearing the seatbelt or not. In this, system again will generate an error signal and after 10 seconds delay the engine will stop.
