The invention belongs to the technical field of downhole vehicle orientation determination, and particularly relates to an downhole vehicle single-station orientation determination method based on accurate positioning, which comprises the following steps of: S1, setting a base station threshold range according to actual conditions of a roadway near a downhole base station; S2, enabling upper computer software to communicate with the base station through a network to obtain a distance value between the vehicle and the base station, the communication information being the vehicle distance; S3, establishing a distance value dynamic trend sequence, and determining whether the vehicle approaches the base station or is away from the base station; and S4, when the vehicle arrives within the threshold range of the base station, switching the orientation of the vehicle according to the driving direction of the vehicle. The downhole vehicle single-station orientation determination method based on accurate positioning has the effect of improving the vehicle position accuracy.
本发明属于井下车辆方位判别的技术领域,具体涉及一种基于精确定位的井下车辆单站方位判定方法,这种基于精确定位的井下车辆单站方位判定方法包括以下步骤:S1、根据井下基站附近的巷道实际条件设置基站阈值范围;S2、上位机软件通过网络与基站进行通信,通信信息为车辆距离,以获取车辆距离基站的距离值;S3、建立距离值动态趋势序列,判定车辆接近基站还是远离基站;S4、到达基站阈值范围内,根据车辆行驶方向进行车辆方位切换。这种基于精确定位的井下车辆单站方位判定方法具有提升车辆位置精度的效果。
