一种本质安全型矿用定位手表设计

Design of an intrinsically safe mining positioning watch

针对煤矿井下便携式定位标签放在腰间在紧急情况不便于求救、不具备液晶显示逃生路线信息、振动时不易被感知等问题,设计并实现了基于本质安全型的高精度定位手表。手表电池输出采用3级保护,实现更高防爆安全等级,利用心率监测传感器实时采集入井作业人员心率状态,监测身体健康状况,手表采用UWB定位技术与巷道基站实时测距,定位精度由米级提高至厘米级,并能够通过UWB通信网络实现手表与地面调度室双向通信,紧急情况下一键井下求救,瓦斯超限时能够接收地面下发的撤离信息,液晶显示逃生路线信息,同时手表发出声音、光、振动多功能报警提示等,为矿工井下安全作业提供更有力的保障。

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 information,and difficulty in perceiving vibrations.The battery output of the watch adopts a three-level protection to achieve higher explosionproof 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 achieve 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 escape route information,and provides multi-functional alerts including sound,light,and vibration,thereby significantly enhancing safety for miners during underground operations.
