Abstract
A collision avoidance system includes an unmanned aerial vehicle (UAV), a UAV controller, and a safety data aggregator. The UAV includes a positional sensor, and is coupled to communicate positional data to the UAV controller, and receive commands from the UAV controller. The safety data aggregator is coupled to communicate with the UAV controller, wherein the safety data aggregator collects positional data from one or more UAV controllers, stores collected positional data in a safety data buffer, and extracts spatially relevant positional data in response to a request from the UAV controller.
Claims14
A collision avoidance system comprising:
- an unmanned aerial vehicle (UAV) having a positional sensor and a communication system configured for bi-directional communication;
- and
- a safety data aggregator coupled to receive positional data associated with UAVs detected by one or more remote sensor networks, wherein the safety data aggregator collects positional data, stores collected positional data in a geo-spatial database, receives a request for spatially relevant positional data from the UAV, wherein the request includes a position of the UAV, extracts spatially relevant positional data from the geo-spatial database within a radius or distance of the position provided by the UAV, and provides the extracted spatially relevant positional data to the UAV, wherein the UAV utilizes the spatially relevant positional data to automatically avoid collisions between the UAV and other UAVs.
A method of aggregating and distributing safety data, the method comprising:
- collecting positional data from one or more remote sensor networks, wherein the collected positional data identifies position of one or more other UAVs detected by the one or more remote sensor networks;
- providing the collected positional data to a safety data aggregator;
- storing the collected positional data in a geo-spatial database that is searchable to provide spatially relevant positional/safety data;
- receiving a request from a UAV for spatially relevant positional data, wherein the request includes a current position of the UAV;
- extracting spatially relevant positional data from the geo-spatial database based on the current position of the requesting UAV;
- and
- providing the spatially relevant positional data to the UAV for collision avoidance analysis;
- and
- utilizing the spatially relevant positional data to automatically avoid collisions between the UAV and the one or more other UAVs detected by the one or more remote sensor networks.
