Multi-function Fast Networking Rescue Life Escort Benan Watch

In order to realize the real-time perception of the status of vital signs of underground mine workers, reduce the potential hazards caused by diseases, and sense the physical condition of trapped miners during the post-disaster rescue process, detect the areas where miners are located. With NRF52832 as the control core, combined with ECG signals and photoelectric solvent pulse wave blood pressure measurement algorithm, real-time monitoring of the heart rate and blood pressure of miners is achieved; Bluetooth 5.0 combined with mesh networking technology is used to detect the area where the miners are located, which solves the current problem that coal mines cannot achieve monitoring of vital signs of operators and transmission line interruptions after disasters. Test results show that the device can improve the operational safety and rescue efficiency of front-line miners.
