Wireless Warning System of Positive Pressure SCBA Based on GPRS

Ordinary positive pressure breathing apparatus only supply the air to firefighters within a certain time, and cannot help to realize the real-time control of the service status of the apparatus, leading to the existence of security risks. In this study, a wireless early warning system of positive pressure breathing apparatus was proposed in response to the actual demand of the fire force based on a combination of GPRS communication technologies, intelligent prediction algorithm of the breathing apparatus, and network-based programming technologies. The system features strong applicability and small error (a working error of ±6%), and thus can satisfy the demand of enhancing the safety guarantee for firefighters on the fire-fighting and rescue scene and is of significant application value.
