基于惯性导航技术的井下电机车精确定位系统

目前矿井运输系统中所采用的射频识别等电机车定位方法,只能检测到电机车在某一区域内,不能实现精确定位.通过对移动目标定位技术、数据通讯技术以及可视化技术的研究,结合对煤矿井下特殊工作条件的分析,提出了将惯性导航技术应用到井下定位系统的方案.利用加速度计和陀螺仪测得井下电机车位置、速度、方向等数据信息,通过无线通讯与有线通讯相结合的方式,将数据传送到井上调度中心计算机,应用组态王软件实时显示井下电机车的精确位置.该系统便于调度员了解电机车实时情况,提高了行车安全和效率,排除了撞车等事故的安全隐患.

Precise Positioning System of Mining Locomotive Based on Inertial Navigation Technology

The positioning method such as radio frequency identification used in the mine transportation system can only detect the specific position of the locomotive, but cannot realize the precise positioning. By studying moving target location technology, data communication technology and visualization technology, combined with the special working conditions of the coal mine, a new mine positioning system used inertial navigation technology was proposed. The information of the locomotive, including location, speed and direction, was measured by accelerometers and gyroscopes. Through the wireless communication and wired communication, the data was transferred to the computer control center, using the Kingview software to show the precise location of the locomotive. This system makes it convenient for control room persons to get real-time information of the electric locomotive, and improves safety and efficiency by removing incidents.
