DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0026] The present disclosure pertains to a monitoring tool, system and/or process for monitoring at least one characteristic of an earth working operation.
[0027] In one embodiment, a monitoring tool includes a tethered vehicle having a sensor. The tether can provide power and/or data transmission for the monitoring tool. The tether can also improve the safety of the monitoring tool. The monitoring tool can be used to monitor at least one characteristic of one or more earth working operation including, for example, the monitoring of earth working equipment (including its usage, performance, components, wear parts, etc.) and/or the earthen material associated with the earth working operation. The monitoring tool, system and/or process can include any or all the features, capabilities, embodiments and/or operations as disclosed for the monitoring tools, systems and/or processes in U.S. Publication No. 2016/0237640 filed Feb. 12, 2016, which is herein incorporated by reference in its entirety.
[0028] With reference to
[0029] The monitoring tool 25 may include a unmanned vehicle 36, a sensor or electronic device 31 supported by the unmanned vehicle, and a tether 40 connecting the unmanned vehicle to a home device 33. In the illustrated example, the unmanned vehicle 36 is an unmanned aerial vehicle (UAV) 36A though land-based vehicles can also be used. The tethered UAV 36A may be in the form of, e.g., a drone, helicopter, blimp, airplane, or other aerial vehicle, and include at least one sensor 31. As one example, the electronic device 31 may be a surface characterization device, e.g., a camera or other device that creates, e.g., a two- or three-dimensional representation (e.g. point cloud) or other representation of at least a portion of the equipment 1A, the components thereof, wear parts 5A, gathered material, earthen material to be excavated, associated equipment, etc. Using a tethered UAV 36A for monitoring equipment, usage, wear parts, etc. has certain advantages, in that, the aerial monitoring tool 25 can, e.g., provide unique vantage points and/or to take readings at virtually any point in the operation without inhibiting the operation, requiring the equipment or other monitored item(s) to be in a particular location and/or orientation, and/or endangering personnel. The unmanned vehicle 36 permits a sensor 31 to closely approach the area(s) of interest (such as components of the equipment, wear parts secured to the equipment, an earthen bank to be excavated, etc.) for secure and reliable gathering of information. The tethered UAV 36A is connected to the home device 33 via tether 40.
[0030] The use of a tether 40 can improve safety of the monitoring operation such that the UAV 36A can only fly in a limited radius of space from the home device 33 as defined by the length of the tether. For example, the tether 40 limits the potential fly space of the UAV 36A to provide a level of safety against the UAV 36A flying into unintended space (e.g., into the earth working equipment, other sectors of the mine, etc.). The use of a tether 40 secured to the unmanned vehicle can also reduce the risk of theft. The tether 40 can be composed of a wide variety of materials so long as they provide sufficient strength, flexibility and/or durability for the anticipated operations. The tether is preferably lightweight, flexible, and thin to minimize the drag and/or interference that can result on account of weather conditions (e.g., high winds) reacting on the tether. This allows the tethered unmanned vehicle 36 to function in more hostile environments. The tether 40 may have a winch system to easily extract and retract the unmanned vehicle 36. The winch system can be biased to automatically eliminate unneeded lengths of the tether from being exposed and catching or becoming tangled on nearby things. The winch system can also improve safety by providing an adjustable tether length to suit different needs and, thereby an adjustable (e.g., reduced) flying space from the home device 33; this can reduce the risk of potential user error and crashes because the tethered drone has a limited spatial radius or area it can roam.
[0031] In another example, the tether 40 may include a conductive wire to power the unmanned vehicle 36, sensor and/or other components on the vehicle. The tether 40 may pass power to the tethered unmanned vehicle 36 from a power source or supply 50 associated with the home device 33 to extend the time the UAV 36A can be airborne and/or increase the number, kind or capabilities of the sensor(s) or other components on the unmanned vehicle. The power supply 50 could, e.g., include one or more battery, generator, or other electrical power source and/or a connection from the home device 33 to another power source (e.g., the earth working equipment, transport vehicle, electrical outlet, etc.). As examples only, the power supply 50 may, e.g., convert alternating current (AC) electricity into direct current (DC) electricity, and the tethered unmanned vehicle 36 may include DC-DC converters to supply lower voltage power to the sensor 31 and other components. The power through the tether 40, in certain embodiments, can allow for virtually unlimited flight or work times rather than being limited by the battery capacity of the drone. The enhanced power can also be useful in running one or more sensors carried by the tethered unmanned vehicle 36 and/or powering other components such as processors, lights, etc. The sensor 31 and/or tethered UAV 36A could include battery power instead of or in addition to power through the tether, which can, e.g., allow for a fail-safe operation, operation when the tether does not transmit power and/or if a power supply is not available at a particular site.
[0032] In another example, the tether 40 may include a wire, optical fiber or other communication transmission conduit to allow the tethered unmanned vehicle 36 to pass signals to and/or from the home device 33. Such signals may include such things as sensor data, software, and/or operating instructions for the tethered unmanned vehicle 36. The tether 40 may exist as a standalone network (e.g. just the home device 33 and the tethered unmanned vehicle 36) or may be a part of a larger network (e.g. network 142). The tether 40 may optionally be encrypted for use with the home device 33 to allow for a more secure transfer of information. In embodiments where data is communicated through the tether 40, the data transmission can be faster, more reliable and/or better secured against unauthorized reception as compared to a wireless signal. The unmanned vehicle 36 may optionally include a wireless transmitter 35 as a supplement or backup to transmitting through the tether 40 or when used with a tether lacking data transmission and/or when a receiver for the tether is not available on site.
[0033] The home device 33 can be carried by and/or secured to, or be one of, a service truck or other vehicle 27 (
[0034] There are a number of off-the-shelf UAVs that could be used or modified for use as the unmanned vehicle of the present disclosure; the unmanned vehicle may also be custom built. For example, the tethered UAV 36A may require an operator to maneuver the tethered UAV 36A by means of, e.g., a joystick. The UAV 36A may be autonomous or a combination of control by operator and by programming for flight, takeoff, and/or landing. In addition, the tethered UAV 36A may automatically hover in place above the earth working equipment 1A; the hover location could be determined by an operator, automatically through use of beacon 37A, sensor 31 and/or other means, and/or by other suitable operations. In another example, the monitoring tool may by such things as programming, sensors, beacons, etc. can maneuver to continuously, periodically, cyclically and/or in other ways monitor at least one characteristic of an earth working operation such as monitoring usage, condition and/or performance of an earth working equipment, its components, wear parts, etc. and/or the earthen material. In another example, the tethered UAV 36A may not require an operator for takeoff or landing and may fly a set pattern before landing. The tethered UAV 36A may coordinate and/or be controlled so as not to land in the same place or location as where the tethered UAV 36A took off.

[0036] With reference to
[0037] The earth working equipment 101B, the transport vehicle 127, the monitoring tool 125, the ground engaging products 115B (e.g. bucket and wear members), the processor, and/or the handheld device 128 (or other HMI) may each be in communication through the communication network 142 or a standalone network between the various devices. As examples, the communication network 142 could include intranets, internets, the Internet, local area networks, wide area networks (WAN), mining site network, wireless networks (e.g. WAP), secured custom connection, wired networks, virtual networks, software defined networks, data center buses and backplanes, or any other type of network, combination of network, or variation thereof. Communication network 142 is representative of any network or collection of networks (physical or virtual) and may include various elements, such as switches, routers, fiber, wiring, wireless, and cabling to connect the various elements of the system 139. Communication between system 139 components and other computing systems, may occur over a communication network 142, tether 140, or other networks in accordance with various communication protocols, combinations of protocols, or variations thereof. It should be appreciated that the network 142 is merely exemplary of a number of possible configurations according to embodiments of the present technology. In other examples, the various components of system 139 may be co-located or may be distributed geographically.
[0038] The monitoring system 139 may include a processor 199 (with, e.g., non-transient memory 200, etc.) having computer instructions, programs, software, firmware, and the like written thereon; all such devices will be referred to herein as processors. In the illustrated example (
[0039] The monitoring tool 125 and/or monitoring system 139 could be used to monitor various characteristics of an earth working operation involving, for example, equipment, products, usage, performance, earthen material, etc. As examples, the monitoring tool 125 may monitor (and/or a processor(s) make determinations regarding) the condition, usage, and/or performance of earth working equipment such as excavators, haul trucks, dredging equipment, conveying equipment, chutes, crushers, mineral processing equipment, etc. and/or portions of the equipment such as lips, buckets, mold boards, sticks, booms, chassis, motive systems, truck trays, hoppers, and other components. The monitoring tool 125 and/or system 139 may, for example, monitor (and/or make determinations regarding) the presence, condition, usage and/or presence of wear parts associated with earth working equipment such as points 15, intermediate adapters 13, adapters 11, noses 15 of a cast lip, shrouds 9, runners, picks, track shoes, blades, corner shoes, hammers, and/or other wear parts. The monitoring tool 125 and/or system 139 may, for example, monitor (and/or make determinations regarding) usage and/or performance of the equipment such as the loads within the bucket, truck tray, hopper, etc., the speed of certain operations such as digging cycles, loading times, conveying times, throughput of mineral processing equipment, etc., the number of digging cycles, etc. The monitoring tool 125 and/or system 139 may, for example, monitor (and/or make determinations regarding) the earthen material such as ore concentration, fragmentation, bank angles, digging paths, etc. before, during and/or after being gathered, processed, etc. by the earth working equipment. The monitoring tool and/or system may also, for example, monitor other characteristics of an earth working operation such as part identification, operational limits, equipment faults, equipment proximity violations, locate system sensors, reading gauges and other operations within a mine site or other worksite where safety, efficacy and/or efficiency can be improved through the use of a tethered unmanned vehicle with a sensor.
[0040] In another example, a monitoring tool 125 can be used to generate data usable to map a mine site or other earth working site to estimate characteristics of the ground-engaging products on earth working equipment used at the site. For example, the gathered data could be used to generate contour-style mapping of wear rates for ground-engaging products to better determine such things as product replacement schedules, costs, etc. In one example, the data gathered by monitoring tool 125 could be combined with other data such as mine geology, GPS data, fragmentation, etc. to make such determinations. The data could be used to map other characteristics or process the site data in ways other than mapping to generate similar information. As other examples, the system can be used to determine such things as timetables for excavating certain material, replacement schedules for products, performance of an operator, etc.
[0041] The monitoring tool 125 and/or monitoring system 139 can monitor and/or determine one or more characteristics that can include information related to earth working equipment (including components, wear parts, etc.), operational limits, locating system sensors, usage, performance, condition and the like. Information related to operational limits may include such things as overfilling equipment, overstressing equipment, etc. Information related to equipment faults may include predetermined values set for maximum wear (e.g. wear profiles for specific ground engaging products). Information related to locating system sensors may include locating system sensors, such as beacons, wear sensors, blast monitoring sensors, road condition sensors, material monitoring sensors, flow monitoring sensors, fill sensors, location sensors, and the like. Information related to part identification can include such things as product type, product number, customer number, brand name, trademark, bill of material, maintenance instructions, use instructions, etc. Information related to usage can include such things as the type of earth working equipment associated with the product, number of digging cycles, average time of digging cycles, location of the product on the equipment, etc. Information related to condition of the product can include such things as wear, damage, temperature, pressure, etc. Information related to performance can include such things as the rate of digging, tons moved per each increment of wear, fill rates, throughput over a period of time, etc. As examples, throughput could include such things as how much material is gathered by a bucket over a period time, how much material is loaded into a haul truck body over time (which could optionally include measuring the loss of material in transfer), how much material is passed through a crusher or other mineral processing equipment over a period of time, how much material is passed through a chute or on a conveyer over time, and the like. As another example, the tethered UAV may spot a first piece of earth moving equipment in preparation for an operation with a second piece of earth moving equipment. For example, a haulage truck in preparation for loading by shovel. Information relating to performance, such as a time for preparation for loading may be measured. This information could also be used to coordinate the tethered UAV 136A into a specific position for better viewing. Using a monitoring tool 125 and especially an airborne unmanned vehicle 136 such as a tethered UAV 136A can be advantageous by permitting a coordinated and efficient monitoring of products on more than one earth working equipment, such as concurrently monitoring, e.g., characteristics such as the earthen bank, the condition and/or loading of a bucket, the presence and/or condition of wear parts on the bucket, the loading and/or condition of a truck body, etc.
[0042] The monitoring tool 125 can include a wide variety of sensors. As one example, the electronic device 131 may generate a two or three-dimensional point cloud representing an outer surface of at least part of a product being monitored. However, various other electronic devices (e.g., cameras, LiDAR, etc.) could be used, and various other ways to assess the equipment and/or products (e.g., optical recognition) could be used. For example, the three-dimensional representation may be generated from more than one two-dimensional optical image captured by a camera 131. Examples of numerous photogrammetry devices, digital cameras, and/or digital single lens reflex (DSLR) cameras could be used to photogrammetrically generate a three dimensional or other representations of the monitored product, load, etc. The sensor may operate continuously, at set times or event-based (e.g., upon receiving a trigger or issuance of the alert). The information gathered by monitoring tool 125 can be provided to the home device 133 and/or a remote device, for processing or use, continuously, periodically, on demand, or in batches. Irrespective of the delivery mode, the system can be operated to provide historical and/or real-time data and/or assessment.
[0043] The monitoring tool 125 can include multiple sensors. In one example, monitoring tool 125 may include multiple surface characterization devices 131 that collect different kinds of information. As an example, the monitoring tool could collect data from a sensor(s) using infrared, visible and/or ultraviolet wavelengths. The collected information can be integrated together to be compared to information stored in a database 194. The monitoring tool 125 could, e.g., collect hyperspectral images that are used to characterize the material of, e.g., the earthen material. Hyperspectral sensors could be such as disclosed in Korean Publication KR101806488, incorporated herein by reference. The sensor(s) could generate X-rays or polarized light that is reflected off collected ore and collected by the sensor on the unmanned vehicle.
[0044] The sensor 131 and/or processor 199 may be configured to generate information on a Human Machine Interface (HMI) 171 (
[0045] The HMI 171 may include information pertaining to what is being monitored. In the example shown in
[0046] The monitoring tool 125 may include a maneuvering device 129 (e.g., an articulated, controlled arm, driven universal joint, etc.) for maneuvering at least one electronic device or sensor 131. The maneuvering arm 129 may be securely connected to the unmanned vehicle 36 at one end 45 and to the sensor 131 at the opposed end 146. In certain examples, the maneuvering device 129 is mounted, so that it can obtain a better view (e.g., a clear line of sight) to monitor the products. The processor 199 may include instructions to control the orientation of the maneuvering device 129. Maneuvering device 129 could, e.g., be a controlled, articulated arm, swivel or other maneuvering implement.
[0047] The monitoring tool 125 and/or separate processor 199 may include instructions to control an electronic device or sensor 131. The sensor 131 is physically coupled with, and/or installed on the unmanned vehicle 136 of the monitoring tool 125 and may be configured to monitor at least one characteristic of an earth working operation, which in one example includes the monitoring of a ground-engaging product. The sensor 131 can optionally work in conjunction with one or more other sensor separate from the unmanned vehicle. A separate sensor can optionally be positioned on the earth working equipment, service vehicle, etc. The sensor 31 on the tethered unmanned vehicle 136 can be a passive or active sensor that collects data.
[0048]
[0049] In one example, a monitoring tool 625 can provide data for a real-time assessment of characteristics of an earth working operation. The electronic device 631 may generate a two (2D) or three-dimensional (3D) point cloud representing a load. In one alternative, the monitoring tool 625 may monitor the load 624 within the truck 601 (e.g., on a truck bed 603) without interrupting the operation of the loading truck 601. Monitoring the load 624 of the truck 601 allows the operators of the earth working equipment to know, e.g., when they have reached a full, evenly distributed load. Overloading truck 601 can lead to premature wear and/or damage and underloading can lead to sub-optimal operation. Monitoring tool 625 could, for example, include concurrent monitoring of the excavating equipment 603, the haul truck 601, the earthen material 624, etc.
[0050] The monitoring tool and/or system may use programmable logic to determine the amount of earthen material within the earth working equipment based on, e.g., a two or three-dimensional profile of the load 624. The monitoring tool and/or system may also determine an estimated weight of the load 624 within the truck 601 based on volume (determined, e.g., from the profile), the degree of fragmentation of the material (e.g. through excavation or through crushing), and/or the ore concentration. The monitoring tool 625 may also verify the estimated weight of the load 624 by comparing the estimated weight to the stated weight from a load monitoring unit installed on the earth working equipment.
