Combined positioning device for the control system of the microtunnel boring machine
The issues of developing a combined positioning device for the microtunnel boring machine control system are considered. A device combining laser and inertial methods of determining coordinates is proposed, which provides the possibility of determining the coordinates and spatial position of the tunneling shield during the construction of straight and curved tunnels by the pushing method. A method for connecting the positioning device with the microtunnel boring machine control system based on the RS-485 wired interface is proposed. A method for calculating coordinates has been developed that takes into account the rotation of the local coordinate system relative to the local geodetic coordinate system.
