Patent Application
20220187830
The present invention relates generally to the field of autonomous vehicle systems. More specifically, the present invention relates to a modular deployment and retrieval system for unmanned sub-carriers.
Use of unmanned sub-carriers is becoming increasingly common and has many advantages across a variety of industries, particularly for performing offshore operations.
While the upfront cost is greater than for hiring workers, the reduced costs and limitations as compared with manual labour make the use of unmanned vehicles an attractive proposition. When using unmanned vehicles crews do not need to be paid and kept in good working conditions and the work limits of divers and human error in all kinds of operations are removed. Offshore operations become less prohibitively expensive and can be carried out with greater frequency.
A switch to relying more heavily on unmanned sub-carriers would also facilitate a personnel transition for marine based organizations, that could instead hire personnel for controlling such operations and leaving the manual labour to the systems.
The problem is that currently available technology requires human personnel to perform the deployment and retrieval operations for the unmanned sub-carriers due to the complex nature of real-world deployment environments. This requirement negates the benefits of using unmanned sub-carriers in the first place and the issue increases with scale, as large-scale deployment of sub-carriers over large areas requires correspondingly large significant investment in sub-carrier deployment and retrieval.
It is within this context that the present invention is provided.
The present disclosure provides a system for autonomously controlling a fleet of carrier platforms on a water body surface, each carrier platform hosting and being configured to deploy and retrieve one or more sub-carriers for autonomously carrying out operations in a marine environment. The one or more carrier platforms and sub-carriers of the system each have navigation and positioning modules for coordinating movements and are also centrally managed via an intelligent central control system from which the operations of the fleet can be monitored and controlled.

One skilled in the art will readily recognize that the above figures are examples and that other architectures, modes of operation, orders of operation, and elements/functions can be provided and implemented without departing from the characteristics and features of the invention, as set forth in the claims.
The following is a detailed description of exemplary embodiments to illustrate the principles of the invention. The embodiments are provided to illustrate aspects of the invention, but the invention is not limited to any embodiment. The scope of the invention encompasses numerous alternatives, modifications and equivalent; it is limited only by the claims.
Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. However, the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term “and/or” includes any combinations of one or more of the associated listed items. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well as the singular forms, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.
The capabilities of sensor technologies such as light detection and ranging (LIDAR), mm wave radar, and Passive infrared (PIR) have progressed to a point where unmanned sub-carriers can outperform human personnel in many situations in the marine environment if they can be effectively deployed to and retrieved from the locations they need to operate in.
With the development of effective low orbit communications satellite systems, ocean signal coverage has also improved dramatically and will continue to do so, opening up a wide range of opportunities for autonomous offshore systems.
The present disclosure provides one such system managed by an intelligent central control module which is capable of autonomously deploying and retrieving various types of unmanned sub-carriers from a carrier platform for extended offshore operations without the need for human personnel.
The system will likely comprise multiple carrier platforms equipped with different sub-carriers for carrying out various operations in various marine contexts. The carrier platforms and sub-carriers can be controlled remotely by an operator, completely autonomously, or in a combination of the two—the level of automation and the automation of new tasks can be controlled via an intelligent central control system.
With reference to
The exemplary system includes an intelligent central control system module 100, a data chain system module 110, a positioning system module 120, a navigation system module 130, a deployment system module 140, a retrieval system module 141, a number of carrier platforms 150, a payload system 160, a number of aerial sub-carriers 170, a number of water-surface sub-carriers 180, and a number of underwater sub-carriers 190.
The central control system module 100 may for example be a central server or base station from which the overall operations of a fleet of carrier platforms 150 can be controlled. It may include an interface for sending various commands to individual sub-carriers via the data chain system 110 over a wireless network, for example a low-orbit satellite communications network providing ocean coverage for communicating with the carrier platforms 150.
A carrier platform 150 may be an unmanned marine vessel or “unmanned surface vehicle” (USV) such as a small boat, equipped with an array of sensors for tracking its environment and geographical position (see
The data chain system 110 is also configured to receive and log position updates and other updates received from the one or more carrier platforms 150 and forward these to positioning system 120 and navigation system 130. These two modules coordinate using the received information to managed routes and movements of the various carrier platforms 150 managed by the system controller 100.
In other examples, instead of a centralized positioning and navigation system, each carrier platform is equipped with its own independent positioning and navigation system and they communicate with one another and with the central control system via the data chain system.
Either way, the navigation and positioning systems comprise algorithms that ensure that carrier platforms 150 take the most efficient routes and do not collide with one another, it also facilitates efficient responses to instructions entered from an operator.
For example, an operator may receive a request or notification that a marine operation needs to be performed at a certain location. The operator can then enter into the system interface of the central control module 100 that a carrier platform is required at that location, and the positioning system 120 and navigation system 130 will coordinate to determine the closest available carrier platform 150 with the appropriate sub-carrier for carrying out the operation, and will route it to the location.
Each carrier platform 150 is also equipped with deployment and retrieving apparatus for various kinds of sub-carriers—for example a nest for an aerial drone sub-carrier, a dock for a water-surface sub-carrier, and a cage configured to be deployed underwater for releasing and retrieving an underwater drone sub-carrier. These mechanisms make up the payload system 160, and they are controlled by a deployment system 140 and retrieval system 141 of the vessel controller, which uses the array of sensors to locate and track the sub-carriers, then wirelessly communicates with them to instruct them when to end their operations and return to the platform 150.
With reference to
The data rendering module 201 provides for and displays mission data for the various carrier platforms and sub-carriers currently deployed on a given body of water or in a geographical region. The mission data can be received from available sources including the positioning system, navigation system, carrier platforms, sub-carriers, and so forth.
The mission data can include but is not limited to: real-time maps with the location of each carrier platform marked and updated in real time, vector graphics indicating the intended routes and future positioning of the various carrier platforms, navigation information such as weather conditions and other environmental factors, status updates from the various carrier platforms and their sub-carriers such as battery levels and damage and wear etc, feedback information on the vessels, sub-carriers and their operations.
The data analysis module 202 provides for data storage, data analysis, early problem detection, problem resolution, mission monitoring, and so forth. For example, the positions and routes of each carrier platform and its associated sub-carriers may be recorded in a log history for that carrier and stored in a database managed by the data analysis module. The information is also analyzed in real time by an intelligent algorithm of the data analysis module designed for managing trajectories and predicting the status of the various deployed vessels in a form of “water AI”.
The central control module 203 communicates with the data chain system 210 and provides for mission control, inputting tasks, controlling the level of automation, automating tasks, and so forth. An operator can thus control which tasks require human control and which are performed on a regular basis autonomously. The control module broadcasts these instructions to whichever carrier platforms and sub-carriers are designated by the operator.
The intelligent central control system may not necessarily require a user to be at a central location to access it. Indeed, a user may be able to access and interface with the system via a water Al platform using application software installed on any wireless device such as may be a mobile handset, mobile phone, wireless phone, portable cell phone, cellular phone, portable phone, a personal digital assistant (PDA), a tablet, a portable media device, a wearable computer, or any type of mobile terminal which is regularly carried by an end user and has all the elements necessary for operation in a wireless communication system. The wireless communications include, by way of example and not of limitation, CDMA, WCDMA, GSM, UMTS, or any other wireless communication system such as wireless local area network (WLAN), Wi-Fi or WiMAX.

In some example scenarios these positioning modules can be radar, sonar, autonomous (relying on internal sensor packages and onboard data processing software), and so forth.
The navigation system 330 comprises: an environment detection module 331, synergy module 332, and a route maintenance module 333. The navigation system will have: an environment detection module to obtain environment information from a variety of sensor packages, including but not limited to optical, laser, radar, and so forth; a synergy module to integrate local environment data obtained by sources with environment information collected from the environment detection module, which may be fed back to the central control system or onboard data processing software to monitor and improve precision, data collection, and so forth; and route maintenance module to integrate environment information from the environment detection module and synergy module to improve navigation, stability, and forth.

The carrier platform 450 also comprises a payload system 440 comprising: a number of aerial sub-carrier payload modules 441, a number of water-surface sub-carrier payload modules 442, and a number of underwater sub-carrier payload modules 443.
As mentioned above with reference to FIG.1, these payload modules are equipment for securing the unmanned sub-carriers to the carrier platform 450 during transit, releasing them at the location of a marine operation, and securing/docking them again once more once they have returned to the vessel. The payload modules may also comprise equipment for charging the power sources of the unmanned sub-carriers while they are docked, or even for repairing damage or replacing parts of the sub-carriers autonomously.
An aerial sub-carrier payload module 441 may for example be a nest station for an aerial drone. A water-surface sub-carrier payload module 442 may for example be a docking port with a mechanical/pneumatic/robotic arm for securing the water-surface sub-carrier to the carrier platform and then retrieving it from the water. An underwater sub-carrier payload module 443 may be a cage which is deployable underwater with a door that can be opened and close to release or secure the underwater sub-carrier.
The carrier platform 450 also comprises various processors for controlling these operations and interfacing with the rest of the system, these processors may be divided operationally into a deployment system 440, a retrieval system 441, and a control module 499—although those of skill in the art will appreciate that all of these modules may in fact comprise one processor or any number of processors.
