Protection suit is vital for fireman’ safety. Traditional protection just physically protects fireman from empyrosis, but can not locate the body injury position impact debris. Herein, we present a wearable debris positioning system alarming based on accelerometer array. The piezoelectric accelerometers with distribute regularly to detect vibration different parts, which conducive injured parts. In addition, parts be displayed dummy model upper computer higher localization accuracy of 4 cm. alarm has rapid response time 0.11ms attributing smart signal processing method. This work provides reliable and method locating assessing debris, significant fire disaster commander rescue in time.
