The present disclosure relates to a modular material tracking system. More particularly, the disclosure relates to tracking material stored on and drawn from a reel using a modular system.
Many materials used in construction or the fabrication of products (e.g., wire, cable, tubing, yarn, rope, etc.) are sold from the manufacturer on reels. Distributing materials on reels allows users (e.g., installers, contractors, manufacturers, etc.) to easily obtain a desired amount of the material for a job or task and enables easier storage and material control. A single reel of material is often used for multiple jobs. Many users manually track the usage of material from a reel while completing jobs. Some types of materials include a visual legend that is printed on the material at given intervals. Tracking the usage of material on reels is often necessary for inventory management, billing, and project planning. Manually tracking the usage of material from a reel requires a significant amount of time and expense and necessitates a system for recording material use. In addition, manual tracking is subject to significant inaccuracies caused by human error. These inaccuracies contribute to waste and increase project cost.
A variety of material tracking systems have been previously developed for materials that are distributed from a reel. Some are generally of the type that attaches directly to the material, independent of the reel and tracks the movement of the line as it feeds from its container. Taymer International, Inc. (Markham, Ontario, CA) is one example of a distributer of measuring devices that are directly attached to the material being distributed. These devices are typically only used in the manufacture of cable because they use a system of complex rollers to measure the material as it is spooled out, which makes this solution expensive and prone to potential errors. This technical approach also requires recalibration of the devices for different material diameter.
Other material tracking systems are used in reel-to-reel audio tape monitoring, as exemplified in U.S. Pat. No. 5,808,824 to Kaniwa, et al. These systems combine reel to reel tape speed measurements with winding radius calculations to control tape feed through a complex series of measuring devices that are integrated with the machine that reads the tape. The system requires complex sensors on both reels along with calculations that feed back into the controlling device and require complex manufacturing and assembly. They are permanent components of the machinery and are not used to track inventory. In this system, the device uses a ratio between the tension of the tape and the torque output of the reel motors to calculate the radius of an empty take-up spool and then ultimately by tracking the tape fed calculations may be made to ultimately determine the radius of the working radius of the supply spool and the length of the fed tape.
Measurement of wire bonding loops is done in semiconductor fabrication as electronic wire is attached to various components as exemplified in U.S. Pat. No. 8,301,841 to Qin. These systems simply calibrate wire payout based on the timing of a payout mechanism and are not used to measure remaining length. They do not measure rotational variables from a spool, reel, or other wire container.
U.S. Pat. No. 6,921,044 to Graber et al shows a device for storing and detecting the end of a wire as it is unspooled. The device uses the few wraps of wire closest to the drum to block the magnetic lines of flux from reaching the magnetic sensor mounted outside of the spool. As the last few wraps of wire no longer block the magnetic flux the sensor will momentarily pick up that flux once per rotation. If the sensor is hooked to an output source (e.g., Light, siren etc.) the output source will energize once per rotation informing the user that the wire is about to run out. Among other potential shortcomings, this device does not provide any advanced warning that the wire will be running out, let alone, provide any inventory management capabilities.
In the fishing gear industry, attempts have been made to develop sensor-based systems to track the amount of fishing line let out from a fishing reel. For example, U.S. Pat. No. 4,790,492 to Takashi provides for magnet-based sensor system for measuring and providing the length of fishing line paid out or reeled in. This unitary system teaches one-to-one correspondence between sensor sub-system, processor, and display. As such, among other potential shortcomings, the approach disclosed by the '492 Takashi patent is too expensive for use in simultaneously tracking multiple reels of material.
Therefore, a need exists to solve the deficiencies present in the prior art. What is needed is a system with a detection component to track and relay the length of material on a reel or spool. What is needed is a tracking system to accurately determine material removed from a reel. What is needed is a sensor module and plate module to provide efficient and flexible monitoring of material removed from a reel or spool. What is needed is a system to aid in selection of a reel for a deployment job. What is needed is a system to centralize information relating to material on various reels. What is needed is a method of tracking material stored on and paid out from one or more reel. What is needed is a method of sensing use characteristics of a reel of material.

The modular material tracking system may operate one or more of these components interactively with other components for tracking material stored on and drawn from a reel using a modular system.
An invention enabled by this disclosure relates to tracking the usage of materials from a reel using a material tracking system.
The controller or first processor 10 may be operably connected via first transceiver 28 to an external device (e.g., a computer, a smart phone, a tablet), which may include a processing unit 16 and user interface 24 (i.e., combinations of software and hardware that are operable to, among other things, calculate the amount of material currently on a reel and activate the one or more indicators 26 or communicate with the one or more external devices). The processing unit 16 may be connected to a memory on the external device and may execute software that is capable of being stored in the RAM (e.g., during execution), the ROM (e.g., on a generally permanent basis), or another non-transitory computer readable medium such as another memory or a disc.
Software included in some embodiments of the material tracking system may be stored in the memory operably associated with the processing unit. The software may include, for example, firmware, one or more applications, program data, one or more program modules, and other executable instructions. The processing unit may be configured to retrieve from memory and execute instructions related to the control processes and methods described below, including for example, the instructions for performing calculations necessary to determine the current amount of material on the reel 30 (see
The PCB may also include, among other components, one or more of additional passive and active components such as resistors, capacitors, inductors, integrated circuits, and amplifiers. These components may be arranged and connected to provide one or more of electrical functions to the PCB including, among other things, filtering, signal conditioning, or voltage regulation. For descriptive purposes, the PCB and the electrical components populated on the PCB are collectively referred to as the battery-powered measurement sub-system 100 (which may also be known as the counting chip). Furthermore, in some embodiments, the PCB includes means for affixing the sub-system 100 to a reel or a reel box. The means for affixing the system can be permanent or removable. In some embodiments, the PCB includes a cover or housing which is affixed to the PCB. The cover or housing can be permanent or, more preferably, removable. Where the reel or reel box is exposed to the elements, the housing can be waterproof or can contain a gasket or seal to prevent water, dust, or other contaminants from reaching the PCB circuitry.
The user interface 24 may be included to control the material tracking system. The user interface may be operably coupled to the first processor 10 to receive or input, for example, physical parameters of a given reel 30 and/or the material stored on the reel for use in tracking usage of the material. Although shown as being associated with a smartphone that uses soft keys, the user interface 24 may include any combination of digital and analog input devices required to achieve a desired level of control for the system. For example, the user interface 24 can be comprised of a computer having a display and input devices, a touch-screen display, one or more of knobs, dials, switches, buttons, faders, and/or the like.
The power supply module 22 may supply nominal voltages to the material tracking system. The power supply module 22 may include one or more batteries or battery packs, and more preferably by one or more rechargeable batteries or battery packs. The power supply modules 22 may also be configured to supply lower voltages to operate circuits and components within the material tracking system.
The communication module 28 may send and/or receive signals to and/or from one or more separate communication modules. Signals may include, among other components, information, data, serial data, and data packets. The communication module 28 may be coupled to one or more separate communication modules via wires, fiber, and/or wirelessly. Communication via wires and/or fiber can be virtually any appropriate network topology known to those skilled in the art, such as Ethernet. Wireless communication can be any appropriate wireless network topology known to those skilled in the art, such as Wi-Fi, Bluetooth, LTE, Zig-Bee, etc.
In some embodiments, the communications module 28 is configured to receive an input. The input is, for example, a streaming input of data values, a data packet, a set of data, etc. The input includes, among other information, an input identifier (e.g., identification number, reel identification index, etc.) for a reel, one or more of physical parameters for a reel (e.g., reel width, reel core volume, etc.), an input identifier (e.g., identification number) for a type of material, data from a sensor 20, and one or more of physical parameters for a type of material (e.g., material length, material outer diameter, etc.). After the input has been received, the input may be transmitted or transferred to the processing unit 16. In another embodiment, at least some processing may be done locally on a processor locally and operatively connected to the sensor, without limitation.

When material is removed from or added to the reel, the reel rotates, which causes the detection element 20 to rotate. In this embodiment, the sensor 18 may transmit a signal each time it detects the proximity of the detection element 20 (e.g., every time the detection element 20 passes the sensor 18). In some embodiments, the signals indicate the current direction of rotation of the reel (e.g., clockwise, counterclockwise). In one embodiment, sensors 18 are magnetic sensors. In alternate embodiments, sensor 18 may be a different type of sensor including, for example, a capacitive sensor, a laser sensor, an optical sensor, an infrared sensor, a touch sensor, accelerometers, etc. In some embodiments, the material tracking system includes one or more of sensors that are spaced apart. Each sensor 18 in the one or more sensors may transmit a signal when the detection element passes. In one embodiment, the detection element 20 may be a type of magnet (e.g., neodymium). In alternate embodiments, the detection element 20 is any type of element appropriate for the type of sensor used in the system.
The first processor 10 may be configured to receive signals from the sensor(s) 18. Upon receiving the signals, the controller 10 may determine whether the reel 30 has rotated in a first direction (e.g., clockwise) or in a second direction (e.g., counterclockwise). In some embodiments, the first processor/controller 10 may receive a separate signal from each sensor 18 in one or more of sensors and determine the rotation direction of the reel 30 based on the order in which the signals are received. For example, the controller 10 may determine that the reel 30 is rotating in a first direction when a signal from a first sensor 18a is received before a signal from a second sensor 18b, and the controller may determine that the reel 30 is rotating in a second direction when the signal from the second sensor 18b is received before the signal from the first sensor 18a.
The processing unit 16 may be configured to determine a new or updated value for the amount (e.g., length) of material on the reel 30. In some embodiments, the controller 10 may determine the new amount of material on the reel 30 using the following equations:
Wherein:
L=starting length of the material on the reel in inches
d=diameter of the material on the reel in inches
n=volume of the core of the reel in cubic inches
w=width of the reel (i.e., distance between the flanges) in inches
xCURRENT=the current value for the length of the material on the reel in inches, and
xNEW=the new value for the length of the material on the reel in inches
In this embodiment, the processing unit 16 may use equation 1 when the reel 30 has rotated in the first direction (i.e., material has been removed from the reel 30). The processing unit 16 uses equation 2 when the reel 30 has rotated in the second direction (i.e., material has been added to the reel 30). Use of inches as the unit of measurement in Equations 1 and 2 are provided for exemplary purposes and any commonly used length unit (e.g., feet, yards, meters, centimeters, etc.) or any fraction thereof can be used, without limitation. In some embodiments, the above-described parameters of the reel 30 and material are retrieved from the memory. In other embodiments, the above-described parameters of the reel 30 and material are received via the communication module 28.
After calculating a new or updated value for the amount of material on the reel 30, the processing unit may transmit an output. The output is, for example, a streaming output of data values, a data packet, a set of data, etc. The output can include, among other things, an identifier (e.g., identification number or reel identification index) of the reel 30, an identifier (e.g., identification number) of the material, and/or the current value for the amount of material on the reel 30. This value can be, for example, in any commonly used linear measurement with inches being one embodiment.
In some embodiments, a second side 42 of the first PCB includes, among other components, a power supply module 22 containing a pair of batteries 44 and a connector 46, as illustrated in
As illustrated in
By way of example, according to an embodiment enabled by this disclosure, a first PCB containing magnetic sensors is affixed at a distance of 6 inches from the central axis of a first end cap that is sized for a reel of wire (Cat 5 Plenum, Anixter, Glenview, Ill.). The first and second end cap are placed on the reel. A sensor, such as an accelerometer or magnetic detection element (#8 Screw Neodymium magnet, Applied Magnets, Plano, Tex.) is attached to a flange of the reel opposite from the first end cap. The reel is placed in a reel box and shipped to a user. The user may program a second PCB with the input identifier by a laptop computer which sends the information wirelessly to the transceiver in the second PCB. The user then attaches the second PCB to the outside of the reel box. As the user retrieves wire from the reel box, the reel rotates and the sensors of the first PCB detect the rotation of the detection element. The sensors send a signal to the second PCB with the number of rotations which can be a whole number or a fractional number. The sensor also detects, tracks, and transmits reverse rotations as wire is replaced or unused wire is rewound. The second PCB may be loaded with software which performs the calculations as described above using either Equation 1 for forward rotation (use of wire) or Equation 2 for reverse rotation (respooling or reloading). The second PCB may then send a signal containing the current amount of wire to the laptop computer for material tracking purposes.
In an alternate example, a first PCB containing optical sensors is affixed at a distance of 1 foot from the central axis of a first end cap that is sized for a reel of wire (18-02 OAS, Lake Cable 529 Thomas Drive Bensenville, Ill.). The first and second end cap are placed on the reel. An optical detection element (Light to digital converter, AMS, Styria Austria) is placed on a flange of the reel opposite from the first end cap. This is repeated for multiple reels of wire. The reels are shipped to a user. The user programs a second PCB with the input identifier of each reel with a smart phone. The smart phone sends the information to a wireless transceiver in the first PCB. As the user retrieves wire from the reel box, the reel rotates and the sensors of the first PCB detect the rotation of the detection element. The sensors send a signal to the smart phone with the input identifier and the number of rotations which can be a whole number or a fractional number. The sensor also detects, tracks, and transmits reverse rotations as wire is replaced or unused wire is rewound.

The frequency at which the sensor 18 may determine angular orientation may be set for a given application, precision, and desired quantity of data produced. In one example, provided without limitation, an accelerometer included in a sensor 18 may determine angular orientation at a rate of 40 Hz. Sensor data may be included in local storage and may processed locally to determine rotations and total amounts paid out. This initial processing being performed locally may advantageously reduce the amount of data having to be transmitted from local memory to global memory. For example, local processing may reduce 40 Hz of sensed raw angular orientation data to 1 Hz of processed data indicative of material paid out, rotational direction, material remaining on the reel, and/or other information. This embodiment may additionally reduce the need for a large local memory, for example and without limitation, to quantities around 4 megabytes, advantageously reducing the cost of materials to produce a system enabled by this embodiment. Alternatively, the raw data read by the sensor 18 may be transmitted to global memory for remote processing and analytics.
Data may be communicated via transceiver, for example, via Wi-Fi, 4G, 5G, cellular data, or networking protocols that would be appreciated by those of skill in the art. In some embodiments, a gateway may be provided to bridge communication protocols between a global network, such as an intranet and/or internet, and a local wireless network between the gateway and the sensor 18.
In this embodiment, the sensor 18 may report its angular orientation for a given positional location, which may indicate a change from a previously reported angular orientation. The change in angular orientation may be analyzed to determine a rate of change, direction of change, number of rotations, and other information relating to the winding or paying out of material included by the reel 30. A location receiver may be included with the sensor to determine a geographic position of the reel 30 to assist with determining whether material is being paid out or whether the reel is simply being rolled for transportation or relocation. The location receiver may use GPS, cellular triangulation, MM waves, ultrawideband tracking, and other location determining techniques to determine a location of a spool or reel. The reading of values from the sensor 18 may additionally be selectable between on and off states manually and/or dynamically from an operator and/or controller.
By including an accelerometer in the sensor, this embodiment advantageously removes the need for additional sensors to be included in a box housing the reel. The sensor may include features to assist with identification, for example, RFID, near-field communication (NFC), Bluetooth, and/or other protocols that would be appreciated by those of skill in the art. For example, the unique identification number may be communicated via one or more of the above features to assist with identification of a reel. Wireless data may be transmitted from the device including the sensor via transceiver and/or radio, which may include and/or interface with an antenna, for example, a PCB antenna, chip antenna, external antenna, and/or another antenna.
In an embodiment, a processing unit 16 on a smart phone (or other portable computing device) may be loaded with an application which performs the calculations as described above using Equation 1 for forward rotation (use of wire), or Equation 2 for reverse rotation (respooling or reloading), and/or another equation. The smart phone application may further provide a spreadsheet on the smart phone screen containing the current amount of wire for each reel by using the unique identification number stored in the memory associated with each reel. This information may then be uploaded at a preferred interval (e.g., per-second, per-minute, hourly, daily, weekly, monthly) to software on a desktop computer in the user's inventory control office.
The basic information regarding the amount of material, time/date, location, and/or other information obtained from the battery-powered measurement sub-system 100 may be manipulated by the processing unit 16 to determine a variety of potentially useful management metrics. For example, the data may easily be mathematically and logically organized and reorganized to determine: (a) the date and time of each pull; (b) location of each pull; (c) accurate billing based on time and materials actually expended at a specific job; (d) reducing overhead and minimizing wasted materials; and (e) maximize installer efficiency. Information may be sharable or saleable to distributors, manufacturers, and other parties to increase efficiencies and better anticipate market demands.
The processing of data may be adjusted to increase accuracy of the calculations, which may be performed locally and/or over a networked computing device. Feedback may be provided to the system regarding calculated payout rates, actual material paid out, margins of error, conditions of the payout, and other factors to improve the accuracy of the system. Calculations may be manipulated through the introduction and alteration of correction factors. For the purpose of this disclosure, a correction factor is intended to include constants, variables, scalar values, calibrations, formulae, and other mathematical operations to manipulate the calculations performed on sensed data to determine usable values and information. For example, a correction factor may be applied to account for the width of cable on a reel, whether the cable is a single conductor, tightness of spooling, respooled material, and other factors.
The feedback may be substantially automatically calculated through use of the system, manually entered, dynamically learned, and/or otherwise received. In one embodiment, a machine learning approach may be used to adjust correction factors based on iterations between multiple operations. For example, machine learning can be used to determine a proposed correction factor, check whether the correction factor improved accuracy of the calculation, and adjust the predictive weight of using the correction factor based on the results. The machine learning operation may be initially based on a rule set. This iterative process can be substantially continually repeated, allowing refinement of the calculation accuracy. The feedback may additionally be used with a fault tree, which may use data science to learn and improve initialization for various operating conditions. Sensors may be associated with information regarding material on a reel to further increase the likelihood of choosing proper correction factors and other variables associated with the material to improve accuracy.
In particular, the system allows an installer, his supervisor, supply ordering clerks to see the length wire remaining in each reel, spool, box, and/or other material-holding apparatus on site and at the office. For an installer on-site, the information means substantially limiting wasted labor time guessing whether a spool will make it to the end of the run; or risking a time exhausting repull. On the other hand, a supervisor would be able to see how many feet of cable have been installed versus the amount of cable use projected for a given job.
In one embodiment, the interface and operations performed by the processor may be updatable. For example, electronic components relating to the sensor and sub-system may be updated via firmware flashing, register editing, configuration files, over-the-air updates, security updates, and other manipulation of data that could affect operation. The sensor and/or additional components may include one or more expansion ports, which may provide additional functionality through supplemental hardware. Solder contacts may additionally be provided for the installation of hardware, for example, a radio or antenna.
Scrapping cable is leakage that most utilities and installers just deal with right now because of the labor cost to sort it out. A tool and system enabled by this disclosure can advantageously and substantially seamlessly provide actionable inventory data that allows users to use a large portion of their cable efficiently. In view of the functionality of the present system, the remaining inventory after a job is complete may be put into ‘My Random Lengths Inventory’ these random lengths will be easily searchable for use at future job sites.
Additionally, reels may be selected such that an amount remaining after a job is a usable quantity that can be used on a future job. Trends may be determined to assist with efficiently ordering cable and wire quantities most likely to be use substantially completely. For example, historic data on how much cable was pulled at which location on which day may be used to assist in spotting trends related to issues with job types or indicate which installers are most efficient.

The enclosure may include seals, liners, and/or other features to minimize or prevent the introduction of moisture, dirt, and dust into an interior volume encompassed by the enclosure. The enclosure may be made of various materials, including plastics, metals, wood, and other materials that will be appreciated by skilled artisans. The enclosure may be configured such that it may be installed in a substantially flush orientation with the reel and/or reel flange. The enclosure may include an antenna operatively connectable to a radio or transceiver. The sensor may include an expansion port, which may be accessible by the enclosure.

A docking interface may be provided to assist removably installing the sensor module 2200 to the plate module 2100. The docking interface may include a plate docking interface 2154 provided by the plate module 2100 and a sensor docking interface 2254 provided by the sensor module 2200. The sensor docking interface 2254 may be removably received by the plate docking interface 2154 to provide a docked physical connection. To remove the sensor module 2200 from the docked physical connection with the plate module 2100, the sensor module 2200 may be slid, lifted, removed, unclipped, or otherwise disconnected from the plate module 2100 to remove the sensor docking interface from the plate docking interface, without limitation.
The plate module 2100 and the sensor module 2200 may include aspects of an electronic interface to facilitate electronic communication by a physical connection, wireless connection, and/or otherwise. In some embodiments, electrical power may be supplied through at least part of the electronic interface, for example and without limitation, from the battery of the sensor module 2200 to the plate module 2100.
The electronic interface may include a plate module electronic interface and a sensor module electronic interface. When the sensor module 2200 is configured in the docked physical connection with the plate module 2100, the plate module electronic interface 2118 may align with the sensor module electronic interface 2218 to create a docked electronic connection, for example, by physical contact of conductors. In one embodiment, the electronic connection may be provided by engagement of pogo pins or other electrical contacts that would be appreciated by a person of skill in the art after having the benefit of this disclosure. When in the docked electronic connection, electronic signals may be selectively communicated via the electronic interface.
While docked, a reel identification index associated with a reel onto which the plate module 2100 is installed may be communicated from the plate module 2100 to the sensor module 2200 via the electronic interface. The sensor module 2200 may then use this reel identification index to retrieve information about the reel to initialize the analytic and material tracking operations. Information about a reel may be provided by the plate module 2100, data stored in memory by the sensor module 2200, retrieved from a network-connected database, or provided in another way that you be apparent to a person of skill in the art after having the benefit of this disclosure.
In one example, a sensor module 2200 may retrieve a length value for the length of the material included by the reel identified by the reel identification index. As material is drawn from the reel, the sensor module 2200 connected to the plate module 2100 and installed to the reel may determine the cumulative forward rotations of the reel occurring subsequent to retrieving the length value. The cumulative forward rotations may be determined as the difference between the number of forward rotations and the number of revers rotations, without limitation. The sensor module 2200 may analyze the cumulative forward rotations to determine the length of the material drawn from the reel. The sensor module 2200 may then update the length value identified by the reel identification index to reflect the length of the material remaining on the reel after at least part of the material is drawn from the reel.
This update may change and/or supplement values stored by the memory of the sensor module 2200, plate module 2100 (in embodiments wherein memory is included by the plate module), or in a network-connected database via the radio frequency transmitter. In one example, the sensor module may be connected to a server and/or database over a network. The server and/or database may provide a global memory accessible over the network via the radio frequency transmitter to communicate at least the reel identification index and the length value. Initial values and information regarding the reel may additionally be accessed and retrieved from the global memory. For example, length values associated with one or more corresponding reel may be stored by the global memory. The sensor module 2200 may be permitted to access and retrieve the length value from the global memory as associated with the reel identification index provided by the plate module 2100. After the draw of material from a reel occurs, length values and/or changes in length values may be updated in the global memory, such as provided by a network communication from the sensor module 2200. Length values stored by the global memory may be displayed to a user via an interface, such as my be provided on a computer, web browser, SaaS platform, application, or otherwise as would be appreciated by a person of skill in the art after having the benefit of this disclosure.
In one embodiment, the sensor module 2200 may further include a clock that outputs time values. The sensor module memory may store time series data relative to the cumulative forward rotations of the reel correlated with the time values. The sensor module 2200 may additionally include a sensor location receiver that outputs a geographic position. The sensor module 2200 may advantageously associate an event in which the material is drawn from the reel with the geographic position at which the material is drawn, providing additional resolution to users about the use of a system enabled by this disclosure. This information may be further interpreted to give useful information such as length of material drawn from a reel, the location at which material was drawn, the amount of material drawn at a location, time stamps, draw rates, and other information. By analyzing the information provided by a system enabled by this disclosure, a processor connected to the global memory may recommend a reel for an anticipated job having sufficient material available while minimizing waste that may be cause by leaving an unknown or unusable amount of material on the reel after a job is complete.
In some embodiments, the plate module may be sold or otherwise provided to customers as a stand-alone product. The plate module may be installed to a reel, spool, or other device without requiring a sensor to be attached at the time of installation, storage, movement, relocation, or other times. Essentially, in this embodiment, the plate module may be intended to remain with the reel as it holds material to be drawn from it. The sensor module may then be temporarily installed to the plate module while material is drawn from reel onto which the plate module is installed to gather data regarding the draw event and communicate such data to server to update a global inventory. The sensor module may then be removed from the plate module once the draw event is complete. These plate modules may include features to be read by sensor modules, sensor devices, readers, smartphone applications, or otherwise even if the sensor module is not attached. Such features may include RFID, QR codes, NFC, Bluetooth, and/or other communication protocols that would be appreciated by a person of skill in the art after having the benefit of this disclosure. Information that may be read from the plate module may assist with identifying the reel, the material remaining on the reel, properties of the material on the reel, location, last use, and other information that would be apparent to skilled artisans.
