Description

FIELD OF THE INVENTION

The present invention relates to an electronic device, monitoring system and method for autonomously tracking, detecting and reporting its installation/re-installation and detachment/removal on a ground engaging tool (GET), as well as the installation/re-installation and detachment/removal status of a GET with electronic monitoring device with respect to a clamping element in an earth moving machine, wherein said GET may be selected from teeth, adapters or protectors, shrouds, sidebar protectors or teeth holders, among others. Said earth moving machine may be selected from a mining shovel, mining loading equipment, among others. The monitoring of the GET is performed autonomously at least from the installation of the electronic monitoring device in the GET until it completes its useful life cycle or until it cannot be detected because its power source is depleted, or the GET could not be located after detachment or lost wireless communication with the network. Monitoring is performed by managing the power consumption according to 4 main operational states of the GET lifecycle (“Standby” state, “Device Installed” state, “GET Installed” state or “GET Detached” state). And additionally, the electronic monitoring device also detects its installation/re-installation and detachment/removal on a GET, as well as the installation/re-installation and detachment/removal of the GET with electronic monitoring device with respect to a clamping element in an earth moving machine by means of magnetic hysteresis curves; amplitude changes in the standing wave in the transmission line of a resonant antenna, changes in the amplitude and phase of a thermally normalized RLC circuit, and by changes in the self-frequency of a self-resonant RLC circuit. The electronic monitoring device is installed inside a GET, in a cylindrical housing cavity in the GET, and maintains continuous wireless communication with the communication network despite the surrounding metallic environment.

BACKGROUND

A GET (Ground Engaging Tools) is a ground engaging tool installed in earth moving machines, e.g. mining shovels, which is intended to be the first contact between the machinery and the ground. These ground engaging tools are designed to protect other more valuable components and must be replaced from time to time due to their accelerated wear. However, there are events where they become completely detached and are mixed with the ore. When this event occurs and the ground engaging tool is not separated from the ore early, it can reach the primary crusher and jam or block it, leading to high economic losses due to unscheduled stoppage, damage to the crushing equipment and putting at risk the lives of the personnel who must remove the GET, for example, from the primary crusher.

To detect the detachment of a GET, cameras or portals with electronic tag readers, such as RFID technology devices, are generally used. However, these technologies or technical solutions fail to effectively detect the detachment, due to the shielding caused by dust, dirt, rocks or ore during the operation of mining equipment, and with it, the noise or distortion of the data or information received from the images of cameras or RFID readers. To overcome this challenge, image-based technologies focus on developing robust image processing software that recognizes detachment, yet they report a large number of false positives (detachment) and negatives (no detachment), and the high processing times slow the generation of GET detachment or non-detachment reports. RFID-based technology, on the other hand, requires the installation of portals through which the loading equipment must pass in order for the detection of the GET detachment to occur and, therefore, the detection is delayed in time with respect to the moment in which the detachment actually occurred.

There are also electronic devices that are related to sensors installed in the locks or pins that hold the tooth with the adapter. However, if the tooth becomes detached from the adapter, the lock may or may not remain attached to the tooth, and if it is not attached to the tooth and falls away from it, the location of the detached tooth will not be known, nor will its detachment be detected. In particular, among the patent documents addressing the technical problem of detecting the detachment of a GET, it is possible to mention U.S. Ser.

DESCRIPTION OF THE INVENTION

The present electronic monitoring device that allows to autonomously track, detect and report its installation/re-installation and detachment/removal, in a ground engaging tool (GET) as well as the installation/reinstallation and detachment/removal status of a GET with an electronic monitoring device with respect to a clamping element in an earth-moving machine, in operation, where said electronic monitoring device is installed/located in a cylindrical housing cavity (11) in the GET. Likewise, this electronic monitoring device autonomously reports its location when the GET moves, and also autonomously detects and reports the installation/re-installation and detachment/removal of the GET. Said electronic monitoring device, said GET or both, have an identifying code or number that is recognized in the wireless communication network. The electronic monitoring device allows recognition that the GET removal is temporary (maintenance/repair/replacement) or permanent (discard/not recovered). Said removal is definitive when the wireless communication network does not detect a change in the “Detached State” of the GET, either because the power source was depleted, the GET could not be located after detachment, or it lost communication with the network. Both the temporary and permanent removal of the GET is autonomously recorded and updated in the GET inventory in a database. Additionally, the electronic monitoring device autonomously reports GET detachment. The electronic monitoring device also allows power management, wireless communication and detection based on 4 main operating states: “Standby” state, “Device Installed” state, “GET Installed” state or “GET Detached” state.

The autonomy in wireless communication, frees it from the use of complementary portals for GET detection since in the present electronic monitoring device has wireless communication from the GET-holding element interface, where said GET-holding element interface is selected from a tooth-adapter, adapter-lip, shroud-lip, sidebar protector-bucket interface, among others. Similarly, by managing power consumption, the electronic monitoring device essentially does not require recharging or changing the power supply means. Likewise, once the power supply is installed, the present electronic monitoring device does not require any human or assisted intervention to change its operating states autonomously.

Hereinafter, unless otherwise specified, the following meanings should be considered:

Said “GET” or ground engaging tool, may be selected from one or more teeth, adapters or protectors, shrouds, sidebar protectors or teeth holders, among others.

Said “GET” or clamping element may be selected from an adapter, bucket lip, bucket, among others. In some embodiments, a clamping element may also be considered as a GET, because it also serves the function of protecting the lip and the bucket. A particular case is the function of the adapter, which holds the tooth, and further protects the lip from wear, impacts and shocks.

Said an “earth moving machine” can be selected from a mining shovel, a mining loading equipment, among others.

Said 4 States of Operation are defined as: 1) State “Standby” or simply “Standby”, i.e., electronic monitoring device, with power source installed, not installed in GET; 2) State “Device Installed” or simply “Device Installed”, i.e., electronic monitoring device installed/re-installed in GET; 3) “GET Installed” or simply “GET Installed” status, i.e., GET with electronic monitoring device installed/installed on a fastening element on an earthmoving machine; or 4) Status “GET Detached” or simply “GET Detached”, i.e. GET with electronic monitoring device detached/detached from a clamping element on an earthmoving machine, in operation or with its useful life cycle ended, or until battery exhausted, or GET was not recovered after detachment or GET lost wireless communication with the network.

The present electronic monitoring device is designed to provide information of its installation/re-installation and detachment/removal status on a GET, as well as the installation/re-installation and detachment/removal status of a GET with electronic monitoring device with respect to a clamping element on an earthmoving machine, despite the surrounding highly metallic environment. The present electronic monitoring device has twin, independent sensing means, located, one at the top, and the other, at the bottom, which can alternate in their operation/activation according to the state of operation and detects its installation/re-installation and detachment/removal, in a GET, as well as the installation/re-installation and detachment/removal of the GET with electronic monitoring device, in an earth moving machine, by one of: magnetic hysteresis curves; amplitude changes in the standing wave in the transmission line of a resonant antenna or changes in the amplitude and phase of a thermally normalized RLC circuit, or changes in the self-frequency of a self-resonant RLC circuit, being also able to communicate wirelessly with the outside despite the highly shielded environments by metallic elements, in which it is located. The electronic monitoring device is designed to protect the internal components from the high temperatures that can reach a GET installed in an earth moving machine, in operation, having a protective casing. Optionally, the present electronic monitoring device may be housed in a housing means for securing it in a cavity (11) in the GET, making the installation of the present electronic monitoring device independent of the size and geometry of said cavity.

Further, a related monitoring system and method is disclosed, which detects the installation status of an electronic monitoring device in a GET, of a GET in an earthmoving machine or both, and the detachment of the GET in an operating earthmoving machine, managing the power consumption of the electronic monitoring device, and establishing wireless communication and detecting based on 4 main operating states: “Standby”, “Device Installed”, “GET Installed”, “GET Installed” or “GET Detached”.

The detection of an event of installation/re-installation or detachment/removal of the electronic monitoring device in the GET or of the GET with electronic monitoring device with respect to a clamping element in an earthmoving machine is based on the generation of low frequency magnetic fields for the creation of hysteresis curves; or amplitude changes in the standing wave in the transmission line of a resonant antenna; or changes in the amplitude and phase of an RLC circuit with thermal normalization; or according to changes in the self-frequency of a self-resonant RLC circuit.

It is worth mentioning that, in general, GET can be manufactured by forging or casting. In both cases, it is not possible that, in the manufacture of multiple GET, the cavities for the installation of a sensor are all perfectly uniform in size and shape. In fact, they vary slightly from one another, on the order of millimeters. Such slight differences in the cavities may cause, if the electronic monitoring device is installed directly in the cavity, that it is tightly or tightly housed in some cavities, while it is loosely or loosely housed in other cavities, and in the latter case, the electronic monitoring device is facilitated to fall due to the permanent vibrations of the earth moving machine carrying the GET and the shocks it receives during operation. Likewise, such a difference may generate significant alterations in the measurements of the electronic monitoring device due to the propagation of errors in time, which influences the effectiveness of the detection of the GET detachment by preventing the establishment of reliable and systematic thresholds for the detection signals.

Said electronic monitoring device may alert of the detachment status of the GET by activating or enabling the generation of visual signals, audible signals, or both. Said means emitting visual signals, auditory signals or both are selected from sirens, horns, loudspeakers, loudspeaker, computer screens or wireless devices with digital display with access to a telephone or satellite network and the Internet, among others. These visual signals are selected from text notes, images or both. Said visual alarms, audible alarms or both, are generated or sent, autonomously, either to the operator of the earthmoving machine or at a monitoring center with a server connected to the network and which is located at the place of operation of the earthmoving machine or both. For example, sending an audible signal and a message with a text notification that is displayed on the screen of a computer, cell phone, Tablet, among others. In this way, the earthmoving machine is prevented from continuing to operate, and the search and recovery of the GET in the ore is made possible.

As already mentioned, the present electronic monitoring device allows the management of energy consumption according to the GET operation status, thus ensuring a low energy consumption, which allows it to reach a useful life period of even up to 2 years, counted from its installation in the GET. The periodicity of data/information transmission is described in Table 1 below:

1Data transmission periodicity: Very low, from 1 hour to 24 hours. Low, from 3 minutes to 1 hour. High, from 0,1 seconds to 3 minutes.
2Status “Standby” = electronic monitoring device, with power source installed, not installed in GET, e.g., may be in storage or on the way to be installed in GET,
3Status “Installed Device” = electronic monitoring device installed in GET, for example, may be stored or on the way to be installed in the earthmoving machine,
4Status “GET Installed” = GET with electronic monitoring device in installation/re-installation on a clamping element of an earthmoving machine, which may be waiting to start operation or on an earthmoving machine operating with new or recovered/reinstalled/replaced GET,
5GET Detached” status = GET with electronic monitoring device detached/detached from a fixture on an earthmoving machine, or with its life cycle ended, or even battery depleted, or GET was not recovered after detachment or GET lost wireless communication with the network.

Thus, the periodicity of data transmission to the server is kept very low prior to the installation of an electronic monitoring device in a GET, and low prior to the installation of a GET with electronic monitoring device on a clamping element of an earthmoving machine, e.g., a loading equipment, and becomes high when the GET with electronic monitoring device is installed on a clamping element of an earthmoving machine, e.g., a loading equipment, or when it has become detached. When the GET is installed on a clamping element of such an earthmoving machine, e.g., a loading equipment, and the latter is in operation, it is sought to effectively detect the detachment of the GET to stop such an earthmoving machine, e.g., loading equipment, early, if the detachment actually occurs, so that the detached GET can be searched for and retrieved, in the ore, and optionally, re-install it. The early shutdown of the equipment prevents the detached GET from moving to other units or operational/productive areas of the mine, such as the primary crusher. Table 2 below shows the management of the wireless communication protocols of this electronic monitoring device, according to the 4 operation states mentioned above, activating in a differentiated way, a communication protocol selected from Bluetooth Low Energy, Lora, Lora Ranging Engine Packet, GFSK or FLRC.

In the “Standby”, “Device Installed” or “GET Installed” states, one of the wireless communication protocols chosen from Table 2 is used and indicated as active by the symbol “X”. While for the “GET Detached” status, a combination of at least two of the 4 wireless communication protocols marked as “active” in Table 2 is used in parallel, thus increasing the chances of detecting an alarm signal from the GET and, optionally, facilitating the search for a detached GET, facilitate the search for a detached GET by activating said communication protocol, together with the “Lora Ranging Engine Packet” protocol that allows detecting the distance between said detached GET and an operator with a module for scanning said wireless signal, thus preventing said detected detached GET from being moved together with the extracted mineral.

As mentioned before, the present electronic monitoring device has twin sensing means that, depending on their location inside the protective outer casing (2), in its upper or lower part, are activated, according to the Operating State, see Table 3.

5Top location, corresponds to a location where the sensing means are located to the inside and at the top of the outer housing (2); the sensing means are in contact with or in close proximity and directed/pointing to the GET attachment element, such location being selected proximate and directed/pointing to the GET attachment element from: 1) proximate and aimed/targeting at the tooth adapter if the electronic monitoring device is installed on a tooth of the earthmoving machine; 2) proximate and aimed/targeting at the lip if the electronic monitoring device is installed on an adapter of a tooth or in-between tooth of the earthmoving machine; 3) proximal and aimed/targeting at the bucket if the electronic monitoring device is installed on a guard of the earthmoving machine, which may preferably be a shovel or loading equipment, where State “Standby”, State “Device Installed”, State “GET Installed”, and State “GET Detached” are as defined for Table 1.

Thus, in the “Standby” or “Device Installed” states, it is the first sensing media twin, located at the bottom, that performs the measurements. While the second sensing media twin, located at the top, performs the measurements in the “Device Installed”, “GET Installed” or “GET Detached” states.

Said external housing means (1) standardizes the installation of this electronic monitoring device, since if it is considered that the cavities (11) of the GET may have dimensions and shapes slightly different from each other, it would be the outer protective housing (2) of the electronic monitoring device that should be adapted/adapted to the cavity, whereas with the presence of the outer housing means (1), the present electronic monitoring device is simply housed inside the outer housing means (1), which in turn, is previously installed in the cavity (11) of the GET, adapting itself to its dimensions and shapes.

In a fourth, simpler embodiment, the present electronic monitoring device comprises a protective outer housing (2), inside which the electronic and programmable components are housed, and is installed directly in the cavity (11) of the GET.

In all embodiments, the protective outer housing (2) of the present device is essentially cylindrical, hollowed out on the inside, and low in height. While the outer housing means (1) has a cylindrical shape, hollowed out on the inside, and is slightly larger in diameter and height compared to the protective outer housing (2), which allows it to freely receive and hold the latter, on the inside.

In the first and second embodiments, the protective outer housing (2) of the present electronic monitoring device is removably attached to the outer housing means (1). While in the first modality, the protective outer housing (2) has at least 2 fin-shaped clamping means (4A) projecting vertically, tangentially and equidistantly from the outer mantle of the protective outer housing (2) that allow it to be attached to the housing means (1) outside. In a second embodiment, the outer housing means (1) has at least 2 fin-shaped clamping means (4B) projecting vertically, tangentially and equidistantly from the inner mantle of the outer housing means (1) that enable it to be attached to the protective outer housing (2).

In a third embodiment, the outer housing means (1) is removably joined to the protective outer housing (2) by threaded attachment, wherein the upper inner surface of the housing means (1) is removably joined by threaded attachment to the upper wide end of the removable cover (7) and the protective outer housing (2) is removably joined by snap-locking means (9) to the lower narrow end of the removable cover (7).

Said fin-shaped clamping means (4) may have different thicknesses, lengths and heights as required in consideration of the dimensions of the outer housing means (1).

Said socket closure receiving means are selected from at least 3 socket closure recesses, preferably “L” shaped (5), and which receive, in removable union, the socket closure means (9) of the removable lid (7), in the first, second and third modalities, or simply receive the socket closure means of a removable lid of smaller size in the fourth modality.

In the fourth mode, that is, in the mode of direct installation of the outer housing on the GET, the removable cover repeats the same gripping feature and additionally features a pair of tabs (12B) to assist reversible closure by engagement with the outer housing (2). In the third embodiment there is only a threaded fastener between the removable cover (7) and the inner upper edge (12C) of the housing means and does not feature gripping means (4A and 4B) as in the first and second embodiments.

The material of the protective outer casing (2), the housing means (1) and the removable cover (7) are selected from a polymeric, co-polymeric material or derivatives thereof or fiberglass, wherein said materials are selected from Teflon, polyaramid, nylon, polyurethane, polystyrene, among others.

FIGS. 10, 11A, 11B, 12A and 12B show the adjusted or adaptable location of the present electronic monitoring device installed within the housing means (1) outside the cavity (11) of the GET (10), according to the size and shape of said cavity (11).
