Granted: 2021-08-11
Abstract: The present invention provides a suspended bridge post inspection method using a fixing clamp assembly member. If photographing the outer circumferential surface of a bridge post at a close range for bridge post inspection, the outer circumferential surface of the bridge post can be safely photographed at a close range by using a camera loaded on a suspended rail assembly member after firmly securing a fixing clamp assembly member on the upper end of the bridge post. The fixing clamp assembly member is firmly secured on the outer circumferential surface of the bridge post by assembling the fixing clamp assembly member in response to the horizontal cross section shape (for example, a circle, rectangle, or inclined shape) of the bridge post, and the suspended rail assembly member is connected by a cable to inspect the outer circumferential surface of the bridge post to be conveniently installed regardless of the installation position (for example, ground or water) of the bridge post and the horizontal cross section shape of the bridge post. Also, bridge post inspection is monitored in real time by an inspector terminal to remotely control the camera and a winding machine driving unit.

Abstract: An embodiment relates to a positioning method for swarm flight based on UWB. Particularly, the positioning method searches for a location in real time in a free space by defining each aerial vehicle as an object on UWB, and positioning the same without a separate anchor, if positioning for swarm flight is performed. In particular, the positioning method provides real-time positioning suitable for swarm flight by calculating the relative position in a swarm formation from UWB TWR-based master/slave ranging scheduling and pull-push relationships. Therefore, the positioning method can increase positioning accuracy for swarm unmanned aerial vehicles, and can control a number of aerial vehicles and unmanned aerial vehicles simultaneously to maintain swarm flight. The positioning method comprises: a third step of calculating the relative positions of master and slave aerial vehicles in formations; and a fifth step of calculating the position of the swarm aerial vehicles by a generated fingerprint map.
