Definitions

  • This invention relates generally to improvements in vending machine information transfer and communication systems and, particularly, to a highly versatile vending machine communication system and process in which it is possible to download and upload vending machine operating software and vending machine data using a handheld data transfer device.
  • vending machines have evolved from purely mechanical devices into complicated, electronically controlled machines. Modem vending machines often employ microprocessors or similar devices that control machine operations. The addition of electronic controllers has facilitated the ability to automatically record and store various types of sales data associated with a given machine. For example, vending machines can store information related to the sales patterns associated with particular vendable products. Such information allows, among other things, vending machine operators to optimize the products they stock in their machines, and to maximize the sales associated with a particular machine and/or with a particular location.
  • Electronic controllers also allow vending machine operators, including service technicians and stock personnel, to tailor various configuration parameters associated with their vending machines. For example, vending machine operators can set parameters related to price data, temperature settings, brewing times, product type, and product location within the machine. In some situations, vending machine operators must update the configuration data quite often. If, for example, the product type or price varies on a regular basis, vending machine service personnel may need to update the configuration data each time the machine is stocked.
  • EVA-DTS electronic data transfer standard
  • the EVA-DTS uses a portable handheld electronic terminal to exchange information with a vending machine.
  • the handheld unit can be preprogrammed using a standard PC and can be loaded with a complete set of configuration data that is subsequently transferred to a vending machine.
  • the handheld unit can read sales and other operational data from the vending machine. Such data may then be displayed directly on the handheld unit or stored for later use by a PC-based system and database.
  • a data transfer protocol is a recognized set and sequence of commands that provide for structured communcations between a vending machine control processor and another electronic terminal such as the handheld unit mentioned above.
  • United States vending machine operators and manufacturers typically prefer a data exchange protocol referred to in the industry as the DEX/UCS protocol.
  • the DEX/UCS protocol uses a 1 ⁇ 4 inch (0.64cm) jack/plug and an associated cable to establish a communication channel between the vending machine and the handheld unit.
  • the EVA-DTS uses a communications system based on the so-called Enhanced Optical Protocol (EOP), defined in the EVA-DTS, Version 4, January 4, 1997.
  • EOP is similar to the Digital Equipment Corporation Data Communications Mesage Protocol (DDCMP).
  • DDCMP Digital Equipment Corporation Data Communications Mesage Protocol
  • the EOP also referred to as the Enhanced DDCMP, basically follows the DDCMP except that the EOP supports higher data transfer rates and uses an IrDA® optical interface.
  • the Infrared Data Association developed the IrDA® optical interface which is commonly used in the palmtop and palm PC industry. It should be understood that although the EOP preferably uses a wireless optical interface, it may also be employed in a conventional jack-and-plug, physical cable configuration.
  • vending machine data transfer systems and devices do not offer vending machine operators with a user-friendly system that fulfills all of their information transfer requirements.
  • current data transfer systems and handheld storage devices cannot be used to download vending machine operating software for use by the vending machine controller.
  • current systems upload vending machine operating software from the vending machine to a handheld storage device.
  • present systems do not facilitate convenient vending machine to vending machine software and data transfers.
  • Existing data transfer devices and systems cannot be easily used to upload operating software or configuration data from one vending machine and thereafter download the uploaded software or data into another vending machine.
  • the invention meets the above needs and overcomes the deficiencies of the prior art by providing an improved system for transferring vending machine operating software and vending machine data. This is accomplished by providing a handheld data transfer device that is adapted to communicate and exchange information with a vending machine controller over wired and wireless communication interfaces.
  • the system also provides software for selecting the vending machine operating software or vending machine data to be transferred, as well as software for controlling various software/data transfer processes.
  • the present invention provides the ability to download and upload vending machine operating software and vending machine data electronically, without opening the vending machine and without replacing EPROMs or similar hardware. Such a system allows for rapid reprogramming of vending machine software during manufacture, test, or in operation.
  • the system further provides for the transfer of manufacturer-specific vending machine data that may be tailored to meet the unique requirements of a particular class of vending machine.
  • this manufacturer-specific data is transferred and stored in binary form, the form most readily used by computers and vending machine controllers. Additionally, the system is economically feasible, commercially practical, and compatible with existing vending machine data transfer protocols.

  • vending machine configuration data and/or the vending machine operational data may be transferred to or from vending machine 12, or between vending machines 12, 12', in the same way that the vending machine operating software may be transferred to or from vending machine 12, or between vending machines 12, 12'.
  • control processor 64 of PDCD 60 may optionally execute software that allows persons operating PDCD 60 to view and edit the vending machine operating software, configuration data, and/or the vending machine operational data on a display (not shown) of PDCD 60. Similar software could also run on base station 74. It should be noted, however, that due to the nature of the type of information stored as operational data, it is unlikely that such data would be edited. Thus, the operational data can be stored in a read-only format. In fact, in one preferred embodiment of the present invention, operational data is not transferred (e.g., uploaded or downloaded) using PDCD 60. In such an embodiment, prior art devices using the DEX/UCS protocol may be used to retrieve vending machine sales or operational data.
  • the configuration data also comprises one or more manufacturer-specific lists that are independent of the lists specified in the EVA-DTS, Version 4, January 4, 1997. Tables I & II are illustrative of typical manufacturer-specific lists.

  • VMC 10 may be programmed using vending machine software that causes VMC 10 to automatically reject lists containing mismatched class identifiers.
  • PDCD may also be used to transfer the configuration data from one vending machine to another vending machine in a similar fashion to that described above with respect to vending machine operating software.
  • PDCD 60 need not be specifically programmed or have any special knowledge with respect to the data other than to know that it is manufacturer-specific list data.
  • One way to identify such configuration data is to use a unique list number that identifies the data as manufacturer-specific data. In other words, PDCD 60 may initiate data transfers simply by reference to a particular manufacturer-specific list number or other convenient identifier.
  • a List 66 may also be created that includes only message data (e.g., the messages displayed on customer display 44).
  • message data e.g., the messages displayed on customer display 44.
  • Such sublists provide flexibility and allow updating and transferring common data between different classes of machines that use a common data structure for like data.
  • the vending machine communication system of the present invention advantageously provides for manufacturer-specific data transfers between similar and dissimilar vending machines even though PDCD 60 requires only very limited information regarding the particular data involved (e.g., only a list number).
  • PDCD 60 may also be programmed to allow a user to view and edit the information contained in any manufacturer-specific list.
  • a sublist code may be embedded within the a primary list identifier.
  • List 66 may be embedded and identified as sublist data within List 65.
  • PDCD 60 only needs to interpret the primary list identifier to determine that the list comprises a manufacturer-specific list-PDCD 60 would not need to be programmed to recognize specific sublists or sublist identifiers.
  • vending machine operating software may also be stored and transferred in a list format. In that way, PDCD 60 need only know the specific list number or identifier when uploading or downloading vending machine operating software.
  • the configuration data and the operational data are transferred and stored in binary form.
  • Prior art systems such as that described in the EVA-DTS specification mentioned above, transfer and store data in ASCII form.
  • Computers and processors such as VMC 10, PDCD 60, and base station 74, on the other hand, cannot readily use ASCII data-the data must normally be converted from ASCII for processing.
  • data remains in binary form.
  • transferring data in ASCII form tends to expand the size of the data formats used and requires the addition of identifiers and delimiters. Consequently, ASCII data transfers require more time and memory than comparable binary data transfers.
  • a vending machine communication system that transfers and stores data in binary form provides distinct advantages in terms of data transfer rates, data storage requirements, and data message size requirements.
  • the vending machine operating software is preferably transferred and stored in binary form.
  • Figs. 4A through 4H illustrate several possible graphical user interface screens for a menu-driven software application associated with PDCD 60.
  • Figs. 4A through 4H illustrate user selection screens that are compatible with a palmtop computer running the WINDOWS CE® operating system.
  • Fig. 4A illustrates a menu selection whereby a person using PDCD 60 may select between an infrared connection using wireless communication channel 70, or a direct connection using physical cable connection 54.
  • Fig. 4B depicts a typical vending machine selection window wherein the selection options are organized by vending machine class. It should be noted that the selection window may also be customized to allow users to select the type of information/data to be transferred (e.g., vending machine operating code, vending machine configuration data, or vending machine operational data).
  • type of information/data e.g., vending machine operating code, vending machine configuration data, or vending machine operational data.
  • Figs. 4A and 4B both show separate "Download” and "Upload” selection buttons. By selecting one of these buttons, a user can initiate a data download or upload.
  • the meaning of the words download and upload may vary among those skilled in the art, depending upon the context in which those words are used. For example, one person might refer to all transfers from PDCD 60 to vending machine 10 as downloads, and similarly refer to all transfers from vending machine 10 to PDCD 60 as uploads. This is the convention generally adhered to herein. Conversely, another person may prefer to refer to such transfers in opposite terms, e.g., referring to all transfers from PDCD 60 to vending machine 10 as uploads. Either convention is acceptable, so long as the terms are used consistently.
  • Figs. 4C and 4D illustrate typical displays indicative of the status of a selected data transfer.
  • Figs. 4E and 4F depict typical file management displays for use with PDCD 60.
  • a file pull down menu allows users to manipulate various file attributes such as file names. Users may also initiate data transfers (e.g., uploads or downloads) from the file menu.
  • Fig. 4G shows a representative list of options available if a user selects the "Start” option associated with a palmtop computer running the WINDOWS CE® operating system.
  • the palmtop application software associated with the vending machine communication system of the present invention is referred to as "nvzap" in the illustrated list of "Start” options.
  • Application software such as nvzap may be created using an object-oriented authoring tool such as Visual C++®, available from Microsoft.
  • Fig. 4H is a typical security feature that may be used with PDCD 60.
  • access to specific data, and to the ability to transfer data may be limited by the use of passwords or similar such devices.
  • base station 74 may also provide additional data manipulation and programming capabilities that are not easily implemented on a handheld unit such as PDCD 60.
  • a computer program executing on base station 74 provides a menu-drive, graphical user interface whereby a user has access to vending machine operating software, operational data, or configuration data in a form that is readable and understandable by the user.
  • Such a program could also allow certain users to edit or otherwise alter the accessed vending machine operating software, operational data, or configuration data.
  • security and integrity checks may control or limit any or all of the above-described data transfer operations.
  • password protections can be used to limit access to data, portions of data, the system, or portions of the system. Access to specific data may be denied altogether or limited in some other way such as "read only" access.
  • password protections may be used to limit a person's ability to initiate data transfers between base station 74 and PDCD 60, and between PDCD 60 and vending machine 12.
  • Other possible integrity checks include embedded codes contained within the data/information exchanged.
  • vending machine 12 can provide a code indicative of a vending machine's class/type to ensure that only software or configuration data associated with that type of machine is downloaded into the operating software memory of that machine.
  • transfer is used broadly herein.
  • software and data transfers are intended to include copying wherein after a transfer occurs, a copy of the original information remains on the source device (e.g., PDCD 60) and a copy of the original information is also stored on the target device (e.g., operating software memory 18).
  • software and data may be literally transferred such that after a transfer, the software and/or data resides on the target device but not on the source device.
  • a transfer can also involve overwriting existing information. If, for instance, a copy of the vending machine operating software already existed in the memory storage 65 associated with PDCD 60, and if an overwrite occurs, the new software that is downloaded to PDCD 60 overwrites the existing software on PDCD 60.
  • the vending machine communication system of the present invention supports partial transfers, partial copies, and partial overwrites of software and data.
