一种低功耗综采工作面人员定位系统设计

Design of personnel positioning system for fully mechanized coal face with low power consumption

现有矿用人员精确定位系统大多采用UWB定位技术,基于人员定位卡+定位分站的布局模式,实现厘米级的高精度定位,但现有模式忽略了工作面环境复杂性以及液压支架安装的分站位置变化对定位精度的影响,以及现场安装的难度等因素。针对上述问题,设计一种低功耗的综采工作面定位系统,采用蓝牙定位和LoRa无线技术,定位器作为信标,采用电池供电,可安装在工作面任意需要定位的位置;人员定位卡融合蓝牙定位和LoRa无线技术,与矿灯融合组成信息矿灯;分站融合LoRa无线模组安装在综采工作面两端,主要负责收集和传输定位信息。该系统可以实现对现有人员精确定位系统的兼容,同时规避现有技术在综采工作面定位中难以解决的问题,具有安装方便、成本低、易维护等优点。

Most of the existing accurate positioning systems for underground personnel adopt UWB positioning technology,which is based on the layout mode of personnel positioning card+positioning substation to achieve centimeter-level high precision positioning.However,the existing models ignore the complexity of the working face environment,the influence of the change of the location of the base station installed with hydraulic support on the positioning accuracy,as well as the difficulty of field installation and other factors.To solve the above problems,a low power consumption positioning system for fully mechanized mining face is designed,which adopts Bluetooth positioning and LoRa wireless technology.The locator is used as a beacon and powered by battery,which can be installed in any position of the working face.Personnel positioning card integrates Bluetooth positioning and LoRa wireless technology,and integrates with mining lamp to form information mining lamp;the substation fusion LoRa wireless module is installed at both ends of the fully mechanized face to collect and transmit location information.The system can be compatible with the existing personnel accurate positioning system,and avoid the problems that the existing technology is difficult to solve in the positioning of fully mechanized mining face.It has the advantages of convenient installation,low cost and easy maintenance.
