摘　　要：针对目前煤矿井下电机车精确定位技术并不成熟的问题,提出了一种基于加速度传感器的电机车实时定位系统,该系统以电机车自身信息与调度信息相结合为基础,阐述了定位原理和具体实现方案,分析了实现此系统的三项关键技术:判断行车方向准确、加速度传感器计算位移准确、无线传输误码率低,并通过设计、改进相关算法解决了关键技术问题.此外,仿真实验与测试实验证明了系统的可行性.Aimed at the problem that the present precise positioning technology of coal mine is not mature, a real-time positioning system of locomotives based on acceleration sensor is presented. On the foundation of locomotives of its information and scheduling information combined, the system introduced the positioning principle and concrete implementation scheme. It also analyzed the three key techniques for realizing this system： the acceleration sensor calculating the shift accurately, judging the driving direction accurately, the low bit error rate of wireless transmission. And it solved the key technique problems through designing and improving the correlation algorithms. In addition, the feasibility of the system is proved through simulation and testing experiments.
