Embodiments described herein generally relate to vending machine controllers and in particular, to a vending machine interface.
A vending machine is a machine that receives currency or other credit from a person, and in return, dispenses things such as food, beverages, cigarettes, tickets, candy, movies, or other such items.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. Some embodiments are illustrated by way of example, and not limitation, in the figures of the accompanying drawings in which:
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of some example embodiments. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details.
Disclosed herein are systems and methods that provide a vending machine interface system. Conventionally, vending machines are stand-alone machines that are not networked. These types of machines require many man hours to visit each machine, check its stock, program item prices or quantities for dispensing, and otherwise maintain the machine. Vending operators have large fleets of vending machines that are expensive to operate and maintain.
Many vending machines have long service lives, with some being in use for years or even decades. Vending operators who wish to take advantage of the increased wireless connectivity that is found nearly everywhere in modern environments, create digital advertising, or process different forms of payment (e.g., cashless payments), are faced with the decision of whether to replace existing vending machine units with new ones or forego these advances. An alternative to a complete machine replacement is a retrofit. The present disclosure discusses an efficient and powerful mechanism to retrofit existing vending machines in a manner that allows them to provide new services.
The VMC 104 registers various activities in the vending machine and controls whether a product is dispensed via the product delivery mechanism 108. The product delivery mechanism 108 may be any mechanical, electromechanical, or other mechanism to control dispensing of products or items in a vending machine. Examples of a product delivery mechanism 108 include, but are not limited to an x-y motor assembly, spiral motor mechanism, flip mechanism, or the like.
The VMC 104 may also monitor sensor data from legacy sensors 106 to determine product availability, dispensing jams, and other indicators of the vending machine status. The legacy sensors 106 may include various contact switches, positional sensors, infrared sensors, or the like to determine the status of, or monitor the status of, various aspects of the vending machine. For example, a sensor 106 may indicate when a product is out of stock, or when a product gets stuck, or when a product is dropped, or when a service door is open. Legacy sensors may include, but are not limited to drop sensors, temperature sensors, optical sensors, tilt sensors, or the like.
The VMC 104 receives payment via the legacy payment peripheral 102, the product selection via the human-machine interface 100, and then triggers the product delivery mechanism 108 when the conditions are right. A drop sensor may be used to determine whether the product dispensed. The drop sensor may be coupled to the VMC 104. If no product was dispensed, then the product spiral may be empty. Various remedial operations may occur in this case, such as allowing the consumer to input a different selection, providing change, or sounding an alert, for example. The VMC 104 may also cause the payment peripheral to dispense change when the amount of currency inserted was more than the purchase price, and update the human-machine interface 100 to show a successful transaction. It is understood that the preceding example is non-limiting, and that other configurations and interactions are considered to be within the scope of this disclosure.
Additionally, the PC platform 150 may provide emulated human-machine interface information to the VMC 104. For example, when the human-machine interface 100 takes the form of a keypad, the keypad information may be transmitted to the VMC 104 so that the VMC 104 responds as though the VMC 104 received the keypad signals directly from the human-machine interface 100. For instance, keypads are often used in vending for product selection and this may be sensed by the PC platform 150 thru general purpose inputs (GPIs) arranged in an XY matrix. When a specific key on the keypad is pressed, the keypad pulls two GPIs low, for example, which denotes the selection.
In addition, legacy sensors 106 and new sensors 110 may be coupled to the PC platform 150. The legacy sensors 106 may be decoupled from the VMC 104 in some installations. In such a configuration, some sensor values from the legacy sensors 106 may be routed through the PC platform 150 to the VMC 104 in order to trigger certain operations, for example. The drop sensor may be initially coupled to the VMC 104. After a retrofit, the drop sensor may be decoupled from the VMC 104 and may be coupled to the PC platform 150. When an item is dropped for vending, the PC platform 150 may detect the drop and send a signal to the VMC 104. In this manner the PC platform 150 may perform additional or auxiliary operations when the drop sensor is activated. For instance, the PC platform 150 may perform accounting functions, inventor functions, user interface functions, etc. in response to the drop sensor triggering.
New sensors 110 may be installed at the time of the retrofit and coupled to the PC platform 150. The new sensors 110 may be used solely for the PC platform 150 or may be used to augment capabilities provided by the VMC 104. Examples of legacy and new sensors 110 include, but are not limited to proximity sensors, biometric sensors, cameras, diagnostic sensors, voltage sensors, current sensors, water flowrate sensors, and the like.
To modify a legacy vending machine architecture 1000 to a retrofitted vending machine architecture 1001, the existing user-inputs, such as an existing LCD, keypad, payment peripherals (e.g., coin mechanism or bill validator), are disconnected from the legacy VMC 104. If the retrofit includes adding a new screen for advertising, product information/selection, etc., then the touchscreen is installed and connected to the PC platform 150. Alternatively a second, larger screen may be added for increased advertisement availability leading to increased value of the advertisement space. The PC platform 150 may drive both screens with the content of each able to be controlled via software and changed remotely. If instead a headless retrofit is to be used, then the previously installed legacy user-inputs (e.g., LCD screen or keypad) may be connected to the PC platform 150. The PC platform 150 may be equipped with ports, connections, circuits, plugs, or other electrical or electromechanical interfaces to connect with legacy equipment. The PC platform 150 may be embedded in the vending machine, and thus referred to as an “embedded PC platform,” in some embodiments. The PC platform 150 may take on various forms including, but not limited to a mobile computer, a mini PC, an industrial PC, a box PC, a gateway controller, or any other compute system that is implemented as part of a larger system.
General purpose outputs (GPO) of the PC platform 150 are used to drive the keypad interface on the VMC 104. The GPOs will drive two outputs low to emulate a product selection on the keypad. Alternatively, the PC platform 150 may communicate with the VMC 104 using a keypad emulator 152 (e.g., a relay board).
The PC platform 150 is then connected to the VMC 104. In an example, the PC platform 150 is connected using an MDB connection and the PC platform 150 is configured to transmit MDB signals over the connection. Of course, other connection types and protocols may be used. The legacy payment peripherals like coin/bill acceptors are then connected to the PC platform 150.
The term “legacy price” or “legacy pricing” refers to the price that was used before the retrofit. The legacy price may be stored in local storage (on the old hardware). Legacy pricing may be obtained as part of the retrofit procedure, such as by selecting each product and recording the price displayed on the front panel of the vending machine, or by using DEX with an interface tool to obtain legacy machine status information such as prices, stock levels, or machine health. An association between legacy pricing and current pricing is then made and stored in the PC platform 150. The legacy pricing (e.g., existing pricing at the time of the retrofit) may be maintained using the PC platform 150 to map revised pricing to legacy pricing and providing the appropriate signals to the VMC 104 to dispense the product.
Alternatively, legacy pricing may be reset to zero currency (e.g., $0.00). In this case, the PC platform 150 does not need to maintain a mapping between the current pricing and legacy pricing. When prices are zero, a free vend is accessed and the VMC 104 automatically dispenses the product when a product selection is received.
As another alternative, instead of setting prices to zero, a test vend signal may be sent from the PC platform 150 to the VMC 104 to dispense a product. The PC platform 150 is used to receive and validate the payment. When appropriate payment is received for the product selection, the PC platform 150 sends a test vend signal to the VMC 104 with the appropriate product selection. The PC platform 150 may send a test vend signal to the VMC 104 through the keyboard emulator 152 or using GPO. In this manner, neither the PC platform 150 nor the VMC 104 needs to maintain a price mapping between current prices and legacy prices.
The PC platform 150 also includes an input/output (I/O) conversion hardware (H/W) 204 to interface with one or more peripheral devices 206A-N. I/O conversion H/W 204 acts as a peripheral interface (I/F) and is used so that the PC platform 150 is able to communicate with legacy peripherals using legacy protocols, such as MDB, CAN, ccTalk, and the like. Peripherals 206A-N may include devices such as bill acceptors, coin acceptors, card readers, keypads, and the like.
Data and information received from sensors 202A-N and peripherals 206A-N may be translated in an application programming interface (API) 208 and made available for consumption by one or more applications executing on the PC platform 150.
A telemetry application 210 is configured to receive data from the sensors 202A-N and peripherals 206A-N. Some or all of data may be stored in an inventory database 212. The inventory database 212 may store information about the vending machine's contents, sales, cash in, cash out, prices, and the like.
A user application 214 is configured to interface with a user, such as with a user interface presented on a legacy LCD screen or on a retrofit replacement touchscreen, for example. The user application 214 allows the vending machine administrator to manage the sensors 202A-N and peripherals 206A-N connected to the vending machine, such as to enable or disable peripheral devices, perform tests or checks of the vending machine, and the like. A system configuration file 216 may be stored with user preferences as set via the user application 214. Historical and other status information may be stored in a configuration database 218.
In the system shown in
Although three applications are illustrated in
The inventory database 212 may be configured to maintain different pricing entries for a single product. The inventory database 212 may include at least two pricing entries, one that reflects the legacy pricing and another that reflects the advertised price. In this way, for the price substitution configuration discussed above in
As discussed above, when a test vend signal mode is used, or when the legacy prices are set to zero, the inventory database 212 does not need to include the mapping between the legacy and advertised prices. However, it is understood that the inventory database 212 may include such information, for example when the same inventory database 212 is used for several machines with different configurations.
With the radios and other communication circuitry, the PC platform 150 is able to receive price changes from a remote location (e.g., a central office), and put price changes into effect in the field immediately. The use of temporary prices, discounts, coupons, frequent shopper rewards, and other incentives and offers may be electronically controlled and easily overlaid on the legacy VMC 104. Prices may vary based on the amount of remaining stock, the shelf life of the stock, events in the venue where the vending machine is installed, time of day, or any other marketing basis.
Accounting may be managed at the vending machine, such as in the inventory database 212 or telemetered to a remote location (e.g., a central office). Various accounting and other management techniques may be used to determine trends in product sales, pricing effects on sales, geographical trends on sales, and the like. Additionally, sensor data may be telemetered to alert a vending machine operator that an item is running low or has been sold out.
A VMC interface (I/F) 222 is used to communicate with the VMC 104. Several channels of communication may be provided between the VMC I/F 222 and the VMC 104, as discussed above, for example a keypad selection general purpose output (GPO), or payment information using a vending machine communication protocol. Additionally, sensor information may be obtained at the PC platform 150 and transmitted to the VMC 104 via the VMC I/F 222.
Thus, in an embodiment, a vending application running on the PC platform 150 maintains different pricing entries in a database, one for the legacy pricing that the VMC is programmed to accept in order to dispense, and the other with the “new” pricing that is presented to the customer. The User Interface for product selection is provided by a touchscreen or LCD/Keypad combination connected to the PC platform 150. A user selects a product at the “new” pricing maintained on PC platform 150. The user pays for product via cashless, coins, or notes. The payment options are a combination of new methods provided by the PC platform 150 and the legacy payment peripherals which are now also connected to the PC platform 150. Once payment is received, the product selection is relayed by the PC platform 150 thru its GPOs to the keypad interface of the legacy VMC 104. The VMC 104 now knows which product it should vend. Next, payment is communicated at the “old” pricing to the legacy VMC 104 via the PC platform 150 emulating one of the legacy payment peripherals (coin mech, bill validator etc.) thru its slave interface.
As an example, the slave interface may be MDB. The MDB protocol supports many ways to send this data. As an illustrative example, assume that the legacy cost of product is $0.70. The PC platform 150 at power up has presented itself to the legacy VMC 104 as a coin mech. It does this by responding to polls to address 08H from the VMC 104. The PC platform 150 then responds to a VMC poll with 0x44 0x04 to indicate $0.20 in coins was deposited. The PC platform 150 responds to a subsequent poll with 0x48 0x08 to indicate $0.50 in coins was deposited. The legacy VMC 104 has now been informed the full payment has been received and dispenses the product. Product is then delivered via the legacy product delivery mechanism.
Alternatively, the PC platform 150 may use a keypad emulator or GPO to transmit product selections, which when the legacy VMC 104 is properly configured, causes the vending machine to dispense the product. The PC platform 150 may instead use a test vend signal to cause the product dispensing.
The peripheral interface 302, inventory interface 304, vending machine controller interface 306, and sensor interface 308 are understood to encompass tangible entities that are physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operations described herein. Such tangible entitles may be constructed using one or more circuits, such as with dedicated hardware (e.g., field programmable gate arrays (FPGAs), logic gates, graphics processing unit (GPU), a digital signal processor (DSP), etc.). As such, the tangible entities described herein may be referred to as circuits, circuitry, processor units, subsystems, or the like.
The peripheral interface 302, inventory interface 304, vending machine controller interface 306, or sensor interface 308 may be incorporated into a computing platform, such as one illustrated in
The peripheral interface 302 may be configured to receive data from a peripheral payment device connected to the vending machine, the data indicating an amount received.
The inventory interface 304 may be configured to determine a current price of a product. In some embodiments, the inventory interface 304 is also used to access a corresponding legacy price of the product. An example inventory interface 304 includes a DEX (digital exchange) port, where various status data may be extracted from a legacy VMC 104 (e.g., sales, stock, or diagnostic information). The current price is the advertised price, and may be stored in an inventory database. The inventory database may be stored in the vending machine interface system 300 or remote from the system 300.
The vending machine controller interface 306 may be configured to transmit a signal to a legacy vending machine controller, the signal causing the vending machine to dispense the product. The vending machine interface system may be used to provide price substitution such that legacy pricing need not be changed when retrofitting the vending machine. As such, in an embodiment, the signal indicates that the amount received via the peripheral interface is at least that of the corresponding legacy price in order to cause the legacy vending machine controller to dispense the product.

As such, in an embodiment, the signal from the vending machine controller interface to the legacy vending machine controller comprises a test vend signal.
In other embodiments, the legacy pricing is reset to zero (e.g., $0.00) so that every product is effectively free. The retrofit vending machine control is then used to monitor cash in and control product dispensing. As such, in an embodiment, the legacy vending machine controller is configured with a legacy price of zero for the product, and the signal is a product selection signal. When the product is set to “free”, the product selection signal alone causes the product to dispense.

As another example, the peripheral payment device may be a network receiver to receive a signal from a transmitter, such as a Bluetooth or Wi-Fi transmitter on a user device. The peripheral payment device may then communicate over a payment network to validate and authorize payment.
In an embodiment, the current price of the product and the corresponding legacy price of the product are different amounts. Of course, the current price and legacy price may be the same as well in some embodiments.

In a further embodiment, the system 300 is to communicate the sensor data to a remote location. In a related embodiment, the system 300 is to communicate the sensor data indicating stock level to a remote location to alert the remote location of a need to restock. Stock information may be kept locally at the vending machine, in combination with remote storage, or instead of remote storage.
In an embodiment, the peripheral interface 302 is connected with a human-machine interface of the vending machine, the human-machine interface used to select a product to vend from the vending machine. In an embodiment, the human-machine interface is a keypad. In a further embodiment, the peripheral interface 302 is to receive a product selection from the human-machine interface, and the vending machine controller interface 306 is configured to communicate the product selection to the legacy vending machine controller.
At block 404, a current price of a product is determined. In an embodiment, a corresponding legacy price of the product is accessed. In an embodiment, the current price of the product and the corresponding legacy price of the product are different amounts.
At block 406, the method 400 includes communicating with a legacy vending machine controller of the vending machine to transmit a signal to the legacy vending machine controller, the signal causing the vending machine to dispense the product.
In an embodiment, the signal indicates that the amount received via the peripheral interface is at least that of the corresponding legacy price in order to cause the legacy vending machine controller to dispense the product.
