摘要
现有主流运输车辆定位方案一般是借助自身传感器采集环境信息,再与地图匹配,从而估计车辆位置.然而,传统车辆定位方法往往应用于单一场景,在真实的煤矿生产交通环境中,地域限制、自车运动状态变化、光线变化、车辆拥堵等复杂场景下,传感器感知信息会受到干扰,导致定位轨迹信号误差增大甚至失败.为了摆脱传统的传感器检测模式的弊端,提出基于北斗卫星+5G技术的煤矿运输车辆自动定位控制器设计方法.设计一种基于北斗卫星技术与5G蜂窝网络融合的车辆定位技术,对煤矿运输车辆展开定位;针对信号源头的随机干扰问题,设计用于车辆定位信号校准的模糊PID控制器,并通过模糊PID控制器完成车辆定位轨迹信号校准.实验结果表明,北斗+5G的模式在煤矿运输车辆自动定位控制中,定位控制精度更好、稳定性更好、实际应用效果比传统的传感器模式更佳.
Abstract
The current mainstream transportation vehicle positioning schemes generally rely on their own sensors to collect environmental information,and then match it with a map to estimate the vehicle position.However,traditional vehicle positioning methods are often applied to a single scene.In real coal mine production and transportation envi-ronments,complex scenarios such as regional restrictions,changes in self vehicle movement status,changes in lighting,and vehicle congestion can cause interference in sensor perception information,leading to increased or even failed po-sitioning trajectory signal errors.In order to overcome the drawbacks of traditional sensor detection mode,a design method for automatic positioning controller of coal mine transportation vehicles based on Beidou satellite+5G technolo-gy is proposed.Design a vehicle positioning technology based on the fusion of Beidou satellite technology and 5G cellular network to locate coal mine transportation vehicles.To address the issue of random interference at the signal source,a fuzzy PID controller is designed for vehicle positioning signal calibration,and the vehicle positioning trajec-tory signal calibration is completed through the fuzzy PID controller.The experimental results show that the Beidou+5G mode has better positioning control accuracy,stability,and practical application effect in the automatic positioning control of coal mine transportation vehicles compared to the traditional sensor mode.
