基于GPS和LoRa的低功耗露天矿电缆定位方法

A low-power open-pit mine cable positioning method based on GPS and LoRa

针对露天煤矿电缆在工作过程中转移频繁、转移范围大,而导致电缆调配效率低、检修和维护不及时,甚至出现电缆遗失和被盗等问题,提出了一种基于GPS和LoRa的低功耗露天煤矿电缆定位方法。该方法为了降低电池损耗,电缆定位设备设置了运动检测功能。当电缆被移动明显时,定位设备可以以很短的发射周期,将GPS定位信息不断通过LoRa网络发送给控制中心;当电缆静止或移动不明显时,定位设备将以相对较长的发射周期发送定位信息给控制中心。辅助于控制中心服务器上的电子地图的电子围栏功能,可以实现电缆的防盗功能。如果电缆出现在预先设定的电子围栏范围外时将向管理员发出防盗警报。控制中心会根据电缆的定位信息做出相应的处理,从而实现监控管理的目的。应用结果表明,此方法简便易行,不仅提高了露天矿电缆的调配、检修和维护效率,还减少了电缆遗失和被盗等情况。

Aiming at the frequent transfer of open-pit coal mine cables during the working process,the transfer range is large,resulting in low cable deployment efficiency,untimely maintenance and maintenance,and even cable loss and theft.A low-power open-pit mine cable positioning method based on GPS and LoRa is proposed.In order to reduce battery loss,the cable positioning device is provided with a motion detection function.When the cable is moved significantly,the positioning device can continuously transmit the GPS positioning information to the control center through the LoRa network with a short transmission period;when the cable is stationary or the movement is not obvious,the positioning device will transmit with a relatively long transmission period.Position the information to the control center.The electronic fence function of the electronic map on the control center server can realize the anti-theft function of the cable.An burglar alarm is issued to the administrator if the cable appears outside of the pre-set electronic fence.The control center will make corresponding processing according to the positioning information of the cable,thereby achieving the purpose of monitoring and management.The application results show that this method is simple and easy,which not only improves the efficiency of deployment,maintenance and maintenance of open-pit mine cables,but also reduces the loss and theft of cables.
