Abstract

Sometimes the road accident happened is out of control, but most of the time,life of victim in the accident can be saved by sending an immediate alert signal to seek help.Usually,before accident happens, emergency brake is being applied and therefore the heat generated can be recovered and converted into electrical energy by using thermoelectric generator (TEG).However,the challenge of energy conversion using TEG is very low and the output voltage may not sufficient to operate an electronic device for sending the signal. The objective of this project is to provide a solution for this problem. Therefore,the solution which is being proposed in this project is designing a self-powered vehicle braking monitoring system using TEG and power conditioning circuit.The power conditioning circuit used is a DC-DC boost converter.The development of this DC-DC boost converter is using LTC3108 to boost up the voltage generated by TEG from conversion of heat from disc brake. From the experiment result,it shows that the output voltage of TEG which is 5V after DC-DC step up and it is sufficient to power up the RF transmitter without the use of battery.The RF transmitter will send signal to RF receiver to activate an alarm and send an email with GPS location to base station.
