COAL MINE AUXILIARY TRANSPORTATION VEHICLE POSITIONING METHOD AND SYSTEM

WIPO Patent Application WO/2023/124340

A1

A coal mine auxiliary transportation vehicle positioning method, relating to the technical field of vehicle transportation positioning. The method comprises the following steps: first, acquiring a rotating speed of each wheel and a steering angle of a steering wheel, respectively constructing a kinematics model based on non-turning wheels of a vehicle and a kinematics model based on turning wheels of the vehicle, and constructing a vehicle geometric center-based kinematics model according to the kinematics model based on the non-turning wheels of the vehicle and the kinematics model based on the turning wheels of the vehicle; and second, according to a travelling status of the vehicle, a, when the vehicle is in a normal travelling state, performing positioning using a combination of the vehicle geometric center-based kinematics model and a strapdown inertial navigation system (1); and b, when the vehicle is in an abnormal travelling state, performing combined positioning using the kinematics model based on the non-turning wheels of the vehicle and the strapdown inertial navigation system (1). The influence of the abnormal state on the positioning precision can be maximized, the positioning precision is improved, the compatibility is high, the precision is high, the method is simple, easy to implement, convenient, and reliable. Also provided is a coal mine auxiliary transportation vehicle positioning system.
