Definitions

  • the invention relates to a system for detecting and rewarding the return of a taken from a collection shopping trolley or luggage cart according to the preamble of patent claim 1 and a corresponding method according to the preamble of claim 8.
  • the system comprises a number of shopping carts, each of which is provided with a contactless identifiable, individual tag, at least one collection point for the shopping carts and collection point detection means located in the area of the shopping cart, the detection means being arranged to provide When recognizing a deferred shopping cart, generate a signal to issue a bonus.
  • shopping cart in the following not only a shopping cart in the strict sense, but also a luggage cart or trolley and the like meant.
  • Self-service shopping markets are usually interested in customers using a shopping cart.
  • the shopping carts are usually kept ready in collection points, from which the customer can remove a cart and take it to the supermarket.
  • experience has shown that the motivation of the customers to return the used shopping carts to the collection point after successful shopping is very low. Instead, the trolleys are often left where they were unloaded - usually in the middle of the parking lot of the supermarket. This creates additional costs for the shopping market, since personnel must be available to collect the abandoned shopping cart. In addition, there is always the risk of damage to parked vehicles and the like through abandoned carts.
  • the shopping carts are provided with deposit locks.
  • the customer can only remove a shopping cart from the collection point when he sets a deposit coin or the like in the deposit lock. The deposit coin will not be released until the shopping cart is properly returned to the collection point.
  • the deposit lock system is perceived in some customer circles as inappropriate regulation and over-regulation.
  • each shopping cart is provided with an electronic transceiver device.
  • a central data processing device recognizes when a shopping cart has passed the cash register and arrived at the collection point, and then issues a bonus in the form of a coupon or a coupon on a lottery.
  • the electronic transceiver devices that must be attached to each shopping cart, cause considerable additional costs in the original equipment and a considerable maintenance through the necessary mobile power supply.
  • shopping carts are often treated with little gentleness, so that must be expected with frequent disturbances of this transceiver device.
  • the present invention is based on the object to further improve a shopping cart-return system and a corresponding method of the type mentioned above and in particular the fact of a proper reset the shopping cart in the designated collection point as inexpensively and yet reliably detect.
  • the invention thus differs from already known feedback systems in that the identification of the shopping carts can be transferred from an active state in which the identification is identifiable by the detection means to a passive state in which the identification is not identifiable by the detection means and / or vice versa, the identification of the shopping cart can be transferred from the passive state to the active state, wherein the transfer from the active to the passive state or from the passive to the active state expediently takes place in connection with the return of the shopping cart to a collection point.
  • This inventive design of the tags of the shopping carts allows the detection means, which can identify the individual tag of each shopping cart, to detect not only the presence of each shopping cart, but by "toggling" the tag (or any adjacent tag) from the active one in the passive state or vice versa receive additional information. For when the switchover from active to passive or from passive to active state is triggered by a process which is to be detected by the detection means, they can detect and report not only the presence of a shopping trolley, but also the course of this process. processed.
  • the process leading to additional information may in particular be the proper return of a shopping cart to the collection point.
  • a bonus it is not enough if the detection means detect the presence of the shopping cart in or near the collection point; Rather, the bonus is issued only then or the signal for the output of the bonus is generated only when it is detected by switching a label from active to passive state or vice versa of the detection means that the shopping cart has been properly set in the collection point.
  • the switching of the identification is preferably carried out only when the identified shopping cart within a predetermined tolerance is set in a provided in the collection point shopping cart stacking row. However, it is also conceivable that the switching of the marking is activated by other actions of the customer to be detected by the detection means.
  • An embodiment of the system is that the identification of a scattered shopping cart, which is not in a shopping trolley pile stack, is basically in its active state, which thereby offers additional advantages that the shopping cart outside the collection point, ie in particular in the supermarket or can be identified at checkout on the basis of their identification.
  • the marking can then change from its active (basic) state to a passive state when a first shopping cart is inserted as soon as a second shopping cart located behind the first shopping cart is pushed into the first shopping cart to form or continue a stacking row.
  • the marking can change from its active (basic) state into the passive state when the second shopping cart is inserted into a first shopping cart in front of it to form or continue a shopping cart stacking row. This is preferably done exactly when the relevant shopping cart is properly set in the stack row.
  • the switchover of the indicators means that only the last shopping cart of a shopping cart stack row has an indicator in the active state. All other tags of the shopping carts set in front of him in the stack row are switched to passive.
  • the invention can be realized very inexpensively, for example by using a pivotable panel as the identification of the shopping cart.
  • the detection means per stack row include a camera, which is arranged at the top of the stack row and each stack row along the recognizes the indicator of the last shopping cart.
  • the corresponding board of the now second to last shopping cart is folded away so that the camera now recognizes and identifies the board of the shopping cart that has just been set up.
  • the identification of the shopping cart that has just been reset thus takes place only when it has been properly inserted into the stack row until the identification of the shopping cart in front of it has been transferred to its inactive state.
  • Such panels can be arranged at the bottom of the shopping cart or attached to a usually already existing hinged rear wall of the shopping cart, being pivoted with this when inserting another shopping cart from a substantially vertical position to a substantially horizontal position.
  • the invention can also be realized in such a way that the identification of the shopping carts, when they are isolated, that is not in a shopping cart stacking row, is basically in its passive state.
  • the identification of a second shopping cart in its active state when this second shopping cart is inserted into a first standing in front of him shopping cart.
  • the detection means can always identify only the last shopping carts standing in a shopping cart stack row, since only this one has an active state tag, this identification being accurate then takes place when the relevant shopping cart has been properly set in the stack row.
  • the state of the identification of a non-empty shopping cart always remains constant, in the present case remains passive. This prevents any manipulation attempts in which the customer drives with the not yet unloaded shopping cart in the collection point, picks up the bonus, and then unloads the shopping cart, after which he then can confidently leave him.
  • the identification of a second shopping trolley then changes from its passive (basic) state to its active state when this second shopping trolley is inserted into a first shopping trolley in front of it, but then returns to its passive state when a third shopping cart located behind the second shopping cart is inserted into the second shopping cart.
  • an activation device may advantageously be provided at the collection point, which changes the state of the identification of a very first shopping trolley, as if it were inserted into a shopping trolley in front of it would have been.
  • each shopping cart can be provided on each shopping cart also several markings to allow the detection from different directions.
  • the shopping cart can be detected by detection means, which work with different orientations.
  • a contactless electronic identification in particular a transponder
  • the transponder can be transferred from an active to a passive state and vice versa. This can be done except by electronic means in a purely mechanical way, namely in which the transponder when inserting the shopping cart in a stack row, for example, pivots so that it comes to rest in a shielding metal housing, or just changes its orientation and so on the detection means is no longer recognized or recognized as being "misdirected".
  • the detection means are designed so that they recognize when a collection point fully occupied and or when a collection point is empty. Because it is common to observe that customers who park their vehicle in a parking lot, which is further removed from the shopping market, remove their shopping trolleys of a nearby supermarket shopping center, but do not bring him back after the purchase, but the nearest collection point of the vehicle to use. As a result, entire shopping trolley stacking rows from remote collection points to the collection points located close to the shopping center have to be spent at regular intervals under corresponding personnel expenses.
  • the detection means can now decide that a shopping cart is set in a collection point that has already been identified as fully occupied, or if it is additionally set in a stack row existing there, the issuing of a bonus can be correspondingly denied.
  • each collection point is provided with display elements which are connected for data exchange with the detection means and perceptible to the outside If a collection point is empty and / or fully booked, customers may already be aware from afar that they must use another collection point in order to receive a bonus. If the detection means of the individual collection points are interconnected for data exchange, even a kind of guidance system can be realized, wherein the display elements refer the customer to the nearest, not yet fully occupied collection point.
  • the already mentioned cameras as part of the detection means according to the invention can be designed with a microprocessor and one or more image recognition sensors, for example as CCD or CMOS cameras.
  • the lenses can have electrically adjustable focal lengths. But it can also be used several image sensors, each equipped with its own lens with different, but fixed focal lengths. As a result, the observation area can be subdivided into a plurality of detection areas, in particular distance areas. This has the advantage that lenses with low-quality imaging properties and image sensors with low photosensitivity can be used. In addition, there need be no control and motion mechanics for the focus of the lens, which could be particularly troublesome at low temperatures.
  • the detection means may be provided with lighting means. This can be done, for example, with LEDs, optionally in the infrared range.
  • the lighting means or the cameras can be triggered by a motion detector, so that the lighting and / or the camera is only put into operation when a shopping cart is actually set in the collection point.
  • the lighting means can also be operated in flash mode, which further reduces the energy consumption.
  • the detection means can be modular, preferably with a central module, with camera modules and possibly with lighting modules.
  • the central module monitors all connected modules, can control them and exchange information.
  • the central module also controls in particular using the data acquired by the camera modules Reading and writing devices for a data carrier of a customer in order to credit him with a bonus.
  • the central module can also control a printer, which then issues a printed bonus credit.
  • the central module is then preferably in the vicinity of the collection point.
  • the corresponding modules can be switched off to energy saving or put into a sleep mode when no one is near the collection point.
  • the central module may further operate an audible and / or visual display unit to display information to the customer, such as the opportunity to receive a bonus for the just-returned cart return, the successful allocation of the bonus or its value.
  • Other information may also be displayed, such as the number of shopping carts in the collection point, the fact that the collection point is empty, or that it can not accept any more shopping carts, so that no bonus will be granted to other shopping carts. This information may preferably be displayed widely visible, such as by means of a display device on the roof of the collection point.

  • the bottom of the shopping cart from above or from below readable mark can be attached, the one from The following or from the preceding shopping cart in a stack row exactly then covered and thus transferred into a passive state, when the two concerned shopping trolley are properly nested. Any mechanical parts for switching the marking are then not necessary.
  • a passive electronic marking is for example a so-called transponder.
  • transponders for example, exploited be transponders depending on position different strong "response" leave. It is also possible to exploit the shielding properties of the metal basket on the shopping cart and, for example, to arrange the transponder, depending on the condition, either inside the basket or outside the basket. On the basis of the different strong response signals of the transponder can be distinguished between the "active" or "inactive" state of the marker.
  • active electronic tags such as small transmitters
  • they can be brought into an active or inactive state by switches attached to the shopping cart.
  • the identification features belonging to a shopping cart can be displayed on the LCD display.
  • the LCD display can change its display state, depending on whether the shopping cart is free, whether the shopping cart is inserted in a previous shopping cart, or whether a subsequent shopping cart is inserted.
  • the display may for example consist of a transparent LCD display, which is mounted under the bottom of the basket.
  • the inactive state of the identification marks can be made thereby that the displays are switched transparent. In the active state, however, they are opaque and indicate the identification feature of the respective shopping cart.
  • system can be used in addition to the described system for shopping cart for any other type of temporary provided dolly.
