Abstract

Abstract: To deal with the problem of the locomotive's dynamically wireless access to transmission network in the mine locomotive unmanned system, the Successive Interference Cancellation (SIC) region partition strategy was proposed. Firstly, the nonlinear region partition model was constructed in the Access Point (AP) communication coverage. Secondly, based on the theoretical derivation, the relationship between the number of region partitions and the AP communication coverage, and the relationship between the locomotive position and the transmission power were found. Finally, SIC region partition strategy was designed. The simulation results show that SIC region partition strategy can make one AP access three locomotives at the same time, and the overall optimization effect of locomotive's total passing time and AP coverage utilization increases at least 50%.

Key words: Access Point (AP), locomotive, wireless access, Successive Interference Cancellation (SIC), region partition

摘要： 针对基于视频监控/识别的井下机车无人驾驶系统中机车动态无线接入传输网络的问题,提出一种串行干扰消除(SIC)区域划分策略。首先,建立基站通信覆盖范围内的非线性区域划分模型;其次,根据理论推导可得区段划分数与基站通信覆盖范围的关系,机车位置与发射功率的关系;最后给出SIC区域划分策略。仿真实验结果表明:SIC区域划分策略使得一个基站可以同时接入3辆机车,机车总通过时间和基站覆盖范围利用率的整体优化效果提高50%以上。
