基于SINS/DR组合导航和地图匹配技术的地铁定位方法研究
Subway location method based on SINS/DR integrated navigation and map-matching technology
摘要
Abstract
With the development of rail transit,subway is playing an increasingly important role in people's daily life.The posi-tioning technology of subway is the key of communication based on train control system (CBTC).Considering that the global positioning system (GPS)can't be utilized in the subway and the ground equipment is complex and expensive,a self-positioning method based on inertial measurement unit (IMU)and speed sensor is put forward,and the track electronic map is used to re-duce the error.This method can suppress the error divergence of Strapdown inertial navigation system (SINS)and reduce the cumulative error of dead reckoning (DR)due to attitude error.In accordance with the particularity of railway lines,using the least squares method to match the line and revise the error caused by the navigation,can greatly improve the positioning accura-cy and reduce the dependency on the ground equipment,and the costs of construction and maintenance can be lowered.关键词
