Abstract
A high-precision positioning watch based on intrinsic safety is designed and implemented to address issues such as inconvenient rescue in emergencies due to portable positioning tags placed at the waist in coal mines,lack of LCD display for escape route informa-tion,and difficulty in perceiving vibrations.The battery output of the watch adopts a three-level protection to achieve higher explosion-proof safety grade.The heart rate monitoring sensor is used to collect the heart rate status of workers entering the well in real-time,monitor their physical health status.UWB positioning technology and tunnel base station are used for real-time distance measurement,and the positioning accuracy is improved from meter level to centimeter level.Through UWB communication network,the watch can a-chieve two-way communication with the ground dispatch room.In emergency situations,one click underground rescue is required,and when gas exceeds the limit,evacuation information is received from the ground.Additionally,it features an LCD display for showing es-cape route information,and provides multi-functional alerts including sound,light,and vibration,thereby significantly enhancing safety for miners during underground operations.关键词
