The invention relates generally to a storage element like a pallet for a warehouse rack, and more specifically, to computing and communication equipment integrated in the storage element. The invention relates further to a method for managing a plurality of storage elements, and a computer program product.
In logistical mass storage facilities huge number of pallets are stored in high racks, and to inventory is very time-consuming and sometimes impossible during normal operations. It has massive impact on operation and costs in case no actual inventory list is available.
Additionally, pallets are not only stored in high racks but also on tracks, trailers, ships, railway wagons and on construction sites in a compact form, i.e., without any space between the pallets. Thus, it is impossible to walk from pallet to pallet and check manually the palletized goods. Such a two-dimensional compact placement of pallets is commonplace in order to use the available storage capacity to a maximum. This is in contradiction to perform inventory operations at any point in time in order to keep track and control the goods actually stored in/on a plurality of storage elements/pallets.
On the other side, there is a strong requirement to control the availability of goods and raw material at any time even if the pallets below the goods and raw material are positioned in a compact form on a surface, like a high rack, a ship deck, a truck or trailer, any intermediate storage space, a construction site, and so on.
Especially, in case no organizational and technical infrastructure is present—like any place outside a high rack—it is difficult to electronically read out inventory data because the pallets are not accessible due to its compact placement in storage lots, including intermediate storage locations.
According to one aspect of the present invention, a storage element—in particular for a warehouse rack—may be provided. The storage elements may be adapted for housing goods. The storage elements may be adapted to be stored compact in at least two dimensions. The storage element may comprise a computing device comprising a memory storing at least a unique identifier and data about the goods housed on/by the storage element. The storage element may also comprise a plurality of antennas external to the computing device and mounted at outer sides of the storage element. The antennas may be adapted for a communication to antennas of neighboring storage elements. The antennas may be electrically connectable to the computing device. Also part of the storage element is a switch controller adapted for switchable connecting one of the plurality of antennas to the computing device at a time.
According to another aspect of the present invention, a method for managing a plurality of storage elements may be provided. The storage elements may be adapted for housing goods. The storage elements may also be adapted to be stored in a compact manner in at least two dimensions. The method may comprise positioning the plurality of storage elements in a plane, i.e., in at least two dimensions, and storing—electronically—at least a unique identifier value and data about the goods housed by one of the plurality of storage elements in a computing device integral to the one storage element. Each of the computing devices may comprise a memory. A plurality of antennas may be mounted at an outer side of each of the plurality of the storage elements. The antennas may be electrically connectable to the related computing device integrated in each respected one of the plurality of storage elements.
The method may comprise further connecting, by a switch controller, one of the plurality of the antennas to the related computing device, and communicating data from one computing device integral to a first storage element to a computing device integral to a neighboring storage element via one of the plurality of antennas of the first storage element to the neighboring storage element via a corresponding one of the plurality of the antennas of the neighboring storage element.
Furthermore, embodiments may take the form of a related computer program product, accessible from a computer-usable or computer-readable medium providing program code for use, by or in connection with a computer or any instruction execution system. For the purpose of this description, a computer-usable or computer-readable medium may be any apparatus that may contain means for storing, communicating, propagating or transporting the program for use, by or in a connection with the instruction execution system, apparatus, or device.
It should be noted that embodiments of the invention are described with reference to different subject-matters. In particular, some embodiments are described with reference to method type claims whereas other embodiments have been described with reference to apparatus type claims. However, a person skilled in the art will gather from the above and the following description that, unless otherwise notified, in addition to any combination of features belonging to one type of subject-matter, also any combination between features relating to different subject-matters, in particular, between features of the method type claims, and features of the apparatus type claims, is considered as to be disclosed within this document.
The aspects defined above and further aspects of the present invention are apparent from the examples of embodiments to be described hereinafter and are explained with reference to the examples of embodiments, but to which the invention is not limited.
Preferred embodiments of the invention will be described, by way of example only, and with reference to the following drawings:
In the context of this description, the following conventions, terms and/or expressions may be used:
The term ‘storage element’ may denote a platform for transporting or storing physical goods. The storage element may take the form of a pallet, a box, a container, a sack, etc. In general, the storage element may have a rectangular form. However, other forms like triangles or circles as ground surface are not excluded.
The term ‘warehouse rack’ may denote a rack in a warehouse with regular rows and columns organized in at least two dimensions alternatively, in three dimensions. Each layer of the warehouse rack—typically a high rack—may allow a compact storage of storage elements.
The term ‘housing goods’ may denote that each storage container is adapted to carry goods. The goods may be positioned on the pallet or in the storage container or in the box acting as storage element.
The term ‘stored compact’ may denote that the storage elements may be positioned side-by-side with just little or no space between adjacent storage elements. No hallways, corridors or aisles may be provided between the different storage elements in one layer.
The term ‘computing device’ may denote a single board computer, single-chip computer or RFID chip equipped with a processor and a respective memory. The computing device may be equipped with a rechargeable battery. The communication to/from the computing device/RFID chip may be performed using antennas for typical RFID frequencies, e.g., 13.56 MHz. However, any other RF communication is as good as the typical RFID frequencies.
The term ‘antenna’ may denote coils positioned within reflectors which themselves are positioned at outer sides of the storage elements, e.g., in the middle of each side of a rectangular pallet. Their primary communication coil is directed in a horizontal direction to a neighboring antenna from another storage container. An external RFID reader—which may optionally function as charger for the rechargeable batteries—may be positioned in front of the respective antenna. Such an RFID reader may be used to read—via the primary contacted storage element—data from all storage elements.
The term ‘neighboring storage element’ may denote a storage element positioned side-by-side or adjacent to another storage element. No space, or hallway, or corridor, may be provided between neighboring storage elements.
The term ‘switch controller’ may denote a controller connected to a switch which may be enabled to connect a resonant circuit to the computing device being integral to the storage element. In receiving mode, the switchable controller may connect one resonant circuit at a time to the computing device/RFID chip. In a receiving mode of the computing device/RFID chip, all four antennas may be connected together to the computing device/RFID chip. The computing device/RFID chip may be enabled to determine which of the plurality of antennas may have received a respective signal.
The proposed storage element for a warehouse rack may offer multiple advantages and technical effects:
Making the storage elements, i.e., pallets or containers, intelligent, enables and enhances the ability to do inventory operations even if the storage elements are positioned in a compact, two-dimensional manner. It is not required to be able to reach each storage element surrounded by other storage elements because the storage elements, i.e., electronic enhancements of the storage elements, are able to communicate from storage element to storage element in a store and forward manner. Any kind of track algorithm may be used in order to read-out the information stored in the memory of the computing devices, e.g., RFID chips, which may be integrated in the storage element. Integrating RFID chips into storage elements like pallets does not represent major additional costs. The RFID chip itself as well as the required antennas may be integrated in this construction of the pallet itself. And thus, the newly integrated technology may be protected by the construction of the pallet.
Additionally, and in contrast to barcodes stuck on the storage elements, the information stored in the RFID chips can be changed anytime reflecting a changed quantity of goods housed by the storage element. No printing of new barcodes and positioning them on the pallet may be required. Also in comparison to a simple bar-code label, the RFID chip can hold/store the list of containing and/or quantity of the goods on the pallet. This self-describing service may also help to re-construct the inventory in case the warehouse management system is down or broken.
The proposed storage element, as well as the related method, may also work outside the contained environment of a high rack, e.g., on construction sites and transport vehicles, like trucks, trailers, ships, containers, and so on.
A read-out of the content of the memory as part of the computing device/RFID chip may be made by an RFID reader positioned at an end of a fork of the forklift or by positioning an RFID reader at any side of the pallet, facing an antenna of a respective storage element in, e.g., a high rack. Thus, the inventory read-out may be performed at any place also outside the contained environment of the high rack. This may ensure a much better control of logistical chains from a storage in a high rack warehouse, via transportation vehicles to storage areas at destinations even if the storage areas are not equipped with the required technology to read-out the goods contained in/on a plurality of storage elements.
In the following some additional embodiment will be described:
According to one advantageous embodiment of the storage element, the switch controller may be a component of the computing device. This may allow a cost-effective implementation and reduces the risk of damage of the computing device/switch controller combination. In one embodiment, the switch may be integral to the switch controller.
According to one optional embodiment of the storage element, the computing device may be connected—in particular electrically—to a rechargeable battery. Alternatively, the rechargeable battery may be an integral part of the computing device. The rechargeable battery may e.g., be a lithium-polymer battery which has the advantage of having a long lifetime and good weight-to-capacity ratio and basically no memory effect. The computing device may be powered by the rechargeable battery. Additionally, the rechargeable battery of the storage element may also be changed using solar panels integrated in the storage element.
According to an additionally optional embodiment of the storage element, the rechargeable battery may be charged by an RFID reader. Thus, an RFID reader may activate the computing device—in particular an RFID chip—and may charge the rechargeable batteries at the same time. However, the rechargeable battery may also be loaded outside communication times by the RFID reader.
According to one permissive embodiment of the storage element, the rechargeable battery may be charged by a voice coil charger. This may allow for a good coupling degree between the charger and the respective antenna.
According to one advantageous embodiment of the storage element, each of the plurality of antennas may comprise an antenna coil, a capacitor and a signal amplifier. Thus, the weak signals from the resonant circuit may not be transferred over a longer distance to the central computing device or RFID chip, but may firstly be amplified.
According to another advantageous embodiment of the storage element, the unique identifier of the computing device may be its IP (Internet Protocol) address. With this, an easy way for unique addresses may be available. Addressing mistakes may be excluded.
According to one additional advantageous embodiment of the storage element, the storage element may be adapted to slide down a wedged warehouse rack. This may have the advantage that—in a layer of the warehouse rack—the first position of the warehouse rack may always be occupied if a storage element is positioned in a row of the warehouse rack. The storage element slides always to the first position at a corridor to enable a read-out of the data in the computing device of the storage element.
According to one preferred embodiment of the storage element, the switch controller may also be adapted for connecting the plurality of antennas to the computing device at the same time in a receiving mode of the computing device. Thus, the computing device may be operable in two modes: (a) in listening mode in which all antennas—e.g., four antennas, one on each side—may be connected to the computing device, e.g., an RFID chip. In an alternative mode—in particular a sending mode of the computing device—one antenna may be selected at one point in time so that a directed communication to a specific neighboring storage element may be possible. This way, the computing element of the storage element may decide in which direction a communication channel may be established to a neighboring storage element.
According to a further advanced embodiment of the storage element, the computing device may be an RFID chip comprising at least a processing unit and an integrated RF receiver, and the antennas of the RFID chip. Hence, an implementation, using an RFID chip as computing device may be pretty cost effective and does not require a high degree of power consumption.
In the following, a detailed description of the figures will be given. All instructions in the figures are schematic. Firstly, a block diagram of an embodiment of the inventive storage element for a warehouse rack is given. Afterwards, further embodiments, as well as embodiments of the method for managing a plurality of storage elements, will be described.
The transportation equipment may, e.g., be a truck, a trailer, a ship deck, a train wagon, or any other place were the storage elements 100 may be positioned, e.g., at a construction site.
Each of a plurality of storage elements 100 may comprise a computing device 102, e.g., an RFID chip 102. However, also other forms of single-chip or single board computers may be used in the context of the proposed system. The computing device has a memory to store at least a unique identifier and data about the goods housed by the storage element. It may be noted that the memory of the computing device may be a non-volatile memory.
The storage element also comprises a plurality of antennas 104, 106, 108, 110 external to the computing device. The computing device may advantageously be positioned in the center of the pallet/storage element below a surface element so that the computing device may be protected easily. Typically, the antennas 104, 106, 108, 110 may be positioned symmetrically at sides of the storage element as shown in the
If the storage element has a rectangular form—as shown in
The antennas are electrically connectable to the computing device, e.g., the RFID chip and a switch controller which is adapted for switchable connecting one of the plurality of antennas to the computing device at a time.
It may be noted that the RFID reader may also be integrated in an autonomous flying drone or a handheld device for reading out the inventory of a complete layer of storage elements positioned in a two-dimensional matrix in that layer. As discussed above, it may not be required that the storage elements are stored in a high rack. The proposed concept also supports the reading out of the memory of the computing devices of the storage elements if the storage elements are placed at any other supporting ground.
Advantageously, the resonance circuit may e.g., be trimmed to 13.56 MHz, the typical frequency for RFID chips. The switch controller 510 controls an electronic switch 512 so that—in a sending mode of the RFID chip 102—only one of the resonance circuits 502, . . . , 508 is connected with the RFID chip. That way, a directed communication to a specific one of neighboring storage containers becomes possible. It may be noted that the resonance circuits are shown without a dedicated signal amplifier. However, it may be useful to position a signal amplifier close to the resonance circuit, so that each resonant circuit may be linked directly to a respective signal amplifier. It may be noted that the switch 512 may be integrated into the switch controller 510 or not.
It may be assumed that the storage element 602 is the start element for reading out the data stored in the memory of the RFID chips of the storage elements 602, . . . , 618. As mentioned above, an RFID reader may be placed in front of the storage element 602, as shown by arrow 620. The RFID chip of the storage element 602 may be activated so that the content—e.g., the unique identifier of the related RFID chip, as well as their stored inventory data of goods housed by the storage element 602, may be read out by the RFID reader. The required reader may also be part of a high rack.
Furthermore, the RFID reader may instruct the first computing device/RFID chip of the storage element 602 to read-out the remaining ones of the other storage elements. A store and forward technology may be used in order to pass the instruction to read-out the data of the RFID chips from RFID chip to RFID chip via the opposing antennas from one storage element to a neighboring storage element. A plurality of algorithms for covering the complete array of storage element 602, . . . , 618 are possible. For example, the sequence may be storage element 602→604→606→608→610→612→614→616, and so on. The store-and-forward technique may be token-based so that the command for reading out a specific RFID chip is accompanied by a position token. If, e.g., the initiating RFID reader at position 620 wants to read-out the inventory of storage element 610, the read-out command may be transmitted from storage element to storage element together with a token vector defining the position of the storage element in the array of storage elements. In this case, the token may comprise the value “4” for a forward position and a value “2” for a “right position”. Each time the token is forwarded from RFID chip to RFID chip, i.e., from storage container to storage container, the respective counter is reduced by a value of 1. In case the counter reaches a value of zero, the respective row and/or column has been reached. Now, the unique ID and inventory data are read-out of the RFID chip and the data travel back to the RFID reader positioned at position 620 with the token technology in the opposite direction if compared to the original direction.
It may be noted that the transmission power and receiving sensitivity of an antenna of each storage system may be increased to a level such that also empty places—i.e., positions in the array where no storage containers are placed—may be crossed. This way, a potentially missing storage container may be approached via another neighboring storage element from a different direction in order to confirm that this spot in the array is indeed empty. On the other side, the strategy may be useful for detecting malfunctioning antennas of the storage elements.
The store-and-forward approach, as discussed above, is illustrated in
If the RFID reader of the, e.g., forklift is positioned at arrow 622 the RFID chip, comprised in the storage element 618, may detect no additional surrounding storage elements. If this is the case, or if no unknown RFID chips/storage elements are available right beside a storage element, it may be concluded that the last storage element in the array has been reached.
Such a determination may also be used to change the direction of the passing command. As an example: the storage container 608/the respective RFID chip may determine that no further storage element is available in the f(orward) direction. Hence, the direction to pass the command further through the array of storage elements is changed from f(orward) to r(ight). A skilled person will understand that the compact array of storage elements may be scanned column by column, row by row or in a mixed mode. As explained above, that way, also empty spaces in the array are detectable as well as defect antennas of the RFID chips/the storage elements.
The method 700 comprises further storing, 704, at least a unique identifier value and data about the goods housed by one of the plurality of storage elements in a computing device integral to the one storage element. Each of the computing devices comprises a memory. A plurality of antennas is mounted laterally at an outer side of each of the plurality of the storage elements. The antennas are electrically connected, 706, to the related computing device integrated in each respected one of the plurality of storage elements by a switch controller.
In case the storage container may have only three sides—a triangle container—or in case of a round container, the number of antennas per computing device/RFID reader may be decreased or increased.
The method 700 comprises further communicating, 708, data from one computing device integral to a first storage element to a computing device integral to a neighboring storage element via one of the plurality of antennas of the first storage element to the neighboring storage element via a corresponding one of the plurality of the antennas of the neighboring storage element. Thus, commands and communication data may be transmitted from one storage element to another storage element, e.g., the respective unique ID of a storage element/RFID chip, as well as the related inventory data describing the content transported with the respective storage element/pallet/container.
Embodiments of the invention may be implemented together with virtually any type of computer, regardless of the platform being suitable for storing and/or executing program code.
The computing system 800 is only one example of a suitable computer system and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, computer system 800 is capable of being implemented and/or performing any of the functionality set forth hereinabove. In the computer system 800, there are components, which are operational with numerous other general purpose or special purpose computing system environments or configurations.

Computer system/server 800 may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system 800. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server 800 may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

The system memory 804 may include computer system readable media in the form of volatile memory, such as random access memory (RAM) 808 and/or cache memory 810. Computer system/server 800 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 812 may be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a ‘hard drive’). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a ‘floppy disk’), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media may be provided.

Such communication can occur via Input/Output (I/O) interfaces 814. Still yet, computer system/server 800 may communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 822. As depicted, network adapter 822 may communicate with the other components of computer system/server 800 via bus 806. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 800. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.
Additionally, an antenna 104, 106, 108, 110 may be connected to the switch controller 510 and/or the switch 512.

In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or act or carry out combinations of special purpose hardware and computer instructions.
