PERSONAL SAFETY NOTIFICATION DEVICE FOR FIREFIGHTERS

摘要

The present invention relates to a personal safety notification device for firefighters, capable of confirming the position of a firefighter by mixing and transmitting a warning signal and an ultrasonic signal through an audio buzzer and then receiving the ultrasonic signal through a control room when the firefighter does not move for a predetermined time. An existing safety device for a firefighter is not proper to track the position of a firefighter suppressing a fire in a building, and an extra device is additionally formed, so the formation is complex. To solve the problem, the personal safety notification device of the present invention is attached to a side of a firefighting suit and includes a temperature sensor sensing the neighboring temperature. If the firefighter does not move for a predetermined time, the movement sensor generates a predetermined electric signal to deliver the signal to a microcomputer, and the microcomputer generates a warning sound of an audible frequency from an audio buzzer by controlling a piezoelectric element operating part while at the same time generating and transmitting a dual ultrasonic signal to the outside to enable a control room to confirm the position of the firefighter. Thus, the present invention is capable of sensing a firefighter who does not move for a predetermined time because of toxic gas or the collapse of a building through the movement sensor, and easily track the firefighter′s position with simple technology by directly generating an ultrasonic signal through the audio buzzer. The present invention is capable of immediately warning the firefighter of a risk factor by displaying the residual amount of air, confirmed through a pressure sensor, and the surrounding temperature, confirmed through a temperature sensor, on an LCD display.;COPYRIGHT KIPO 2017
