Definitions
- the invention relates to an arrangement for displaying product and price data by means of individually addressable electronic display signs, with
- a central computer which includes a data memory for storing the product and price data of individual products in connection with the address of the display label assigned to the respective product,
- At least one input unit for entering the product and price data in the central computer, a plurality of display signs, which have at least one electronically controllable display surface, a transmitter / receiver unit for data transmission by means of electromagnetic signals and solar cells
- an electromagnetic signal transmitting and receiving transmission unit which transmits the product and price data from the central computer to the transmitting / receiving units of the display signs and which receives confirmation signals for logging the data transmission which are transmitted by the transmitting / receiving unit of the display signs, and
- At least one price display unit in particular an electronic re-cash register.
- Such arrangements are particularly suitable for specifying the price and the product name in a large supermarket or department store, in which over ten thousand different articles are often offered.
- Such price information systems ensure that the prices assigned to the individual products on the store shelves are identical to the prices which are calculated at the cash register. This is when the products are labeled with Paper labels are possible only with great effort and the information level of the cashiers is often not or no longer the same as the price on the price label.
- the price display units calculate, ie. H .
- the displayed price after entering the product-related data (e.g. via a keyboard or using a barcode reader) into the cash register, the price displayed at the point of issue of the goods is queried from the central computer and by
- central computer encompasses any suitable electronic data processing unit and not exclusively a single computer unit.
- the central computer can also be formed by a network consisting of several computers, which can access the components of all computers as a data processing unit.
- a price information system is disclosed here in which the display signs are provided with solar cells.
- the solar cells convert the ambient light, for example the light from the department store lighting, into electrical energy with which the display sign is operated.
- no batteries need to be replaced on the display signs or recharged by connecting them to the mains, which results in considerable labor savings.
- With ten thousand different display signs within a price information system even with a battery life of over 1 year, there would be an average of over 25 batteries to be replaced per day. This battery replacement can be completely avoided by using solar cells.
- the price and product data are usually transmitted to the display signs when the supermarket or the department store is closed.
- the functionality of the display signs is also checked by individual control queries.
- With ten thousand display signs for ten thousand different products there is a communication time of around 5 seconds per display sign with ten hours of shop opening.
- the central computer is also required for other services (bookkeeping, warehouse management,...), Time problems can arise when communicating with the display signs. Communication can also be hindered by the fact that there is poor radio contact between the transmission unit and individual, distant display signs. An error-free signal transmission is ensured by keeping a complete radio protocol. Poor transmission quality, however, can significantly increase transmission times.
- the object of the invention is to provide an arrangement for displaying product and price data by means of individually addressable electronic display signs, in which the reliability of the transmission of the data to the display signs enlarged and the duration of this data transmission is reduced.
- the price information system comprises further, additional transmission units which each serve for data communication with a sub-group of the display signs located within a locally limited section, send and receive electromagnetic signals, the frequency of which corresponds to the frequencies of the signals assigned to other transmission units is different, and have a local computer with a local data memory.
- LAN Local Area Network
- the considerably slower radio data transmission to the transmitting / receiving units of the display signs and the logging of the data transmission is carried out by the computers of the various transmission units.
- the computing power of the central computer can be used for any other tasks.
- each transmission unit sends signals of different frequencies that do not interfere with each other.
- Each transmission unit is intended for communication with a subset of the display signs within a locally restricted section, so that none are excessive there are large distances between the transmitting / receiving units of the display signs and the assigned transmission units. Due to the limitation of the length of the radio link and the associated increase in reception quality, the time required for data communication with all display signs is additionally reduced.
- Data communication with the display signs preferably also takes place during the opening time of the sales outlet.
- the transmission power of the transmission units should be reduced so that they only generate weak electromagnetic fields and the customers in the shop are only slightly affected by the radiation from these fields (electro-smog).
- Barcode reading devices are particularly suitable for entering the product data into the central computer, with which the product information printed on the product packaging in the form of barcodes can be detected.
- the barcode reading devices can be used both when the product data is first entered in connection with the product price in the central computer and for the repeated input of the product data at the cash register.
- a manual input device which for example comprises a portable keyboard with an LCD screen, can be provided with which manually entered data can be transmitted to the central computer via one of the transmission units.
- a manual input device enables the transfer of count data during the inventory, i. H. on the number of products on the shelves.
- At least one manual input device can also be provided, with which on-site, ie. H. directly at the sales shelves and tables, data on the
- Display signs can be transferred. So an employee can change prices not only via the central computer, but in the Enter the postings. These changed price data are then acquired by the transmission unit during data communication between the transmission unit and the transmission / reception unit of the display plate and then transmitted to the central computer.
- the solar cells are arranged behind the display surface, which consist of a largely translucent LCD display.
- the display surface which consist of a largely translucent LCD display.
- an additional area for the arrangement of the LCD display can be omitted and the display plate can be made very compact.
- the price information system can be provided with different display signs, the signal transmission frequency of which corresponds in each case to the signal transmission frequency of a specific transmission unit.
- uniform display signs with adjustable signal transmission frequency can be provided, with the frequency of the assigned transmission unit being set for each display sign.
- each display sign should be provided with a rechargeable energy store into which the electrical energy generated by the solar cells is fed.
- the energy store should be as stable as possible, i. H. have a long lifespan.
- a capacitor with a very high capacitance such as e.g. are sold under the name "Gold Caps" with capacities of up to 1 farad.
- Fig. 1 shows a schematic side view of the arrangement according to the invention
- 2 shows a schematic circuit diagram of the arrangement
- Fig. 3 the top view of a sales room in which the arrangement according to the invention is used.
- shop shelves 1 are shown schematically, each comprising three shelves 2 arranged one above the other.
- the display signs 3 for displaying the individual product data and the product prices are attached to the front of each shelf 2.
- transmission units 5 which consist of a computer with a database and a transmitting / receiving unit for data communication.
- the two transmission units 5 shown in FIG. 1 are connected to the central computer 9 of the price information system via a coaxial cable 8.
- a coaxial cable 8 All other known transmission cables or data connections for LANs (Local Area Networks) are also suitable for the data transmission between the computers of the transmission units 5.
- a cash register 10 is connected to the central computer 9 via the coaxial cable 8.
- Each display plate 3 has an individual address, so that the data transmission from the central computer 9 via the transmission units 5 is carried out individually to each display plate 3 become can.
- the individual components of the price information system from Fig. 1 go from the in Fig. 2 shown illustration.
- the central computer 9 is connected via a computer network (LAN) to a large number of transmission units 5, which likewise comprise a computer, and to a number of cash registers 10, only one of which is shown.
- Communication between the central computer 9 and the display plates 3 of the price information system takes place via radio signals which are emitted by the antenna 6.
- the display signs 3 each comprise a transmission / reception unit (not shown) for communication with the
- Further components of the display signs are an electronically controllable display surface 11, preferably an LCD display, and several solar cells 12 for supplying energy to the display signs.
- the price information system shown works as follows: data groups containing the information are stored in the central computer 1 in a database. Product data 25. Price data
- Each transmission unit 5 transmits the price and product data to the display signs 3 with the corresponding address, this display sign 3 confirming sends back signals for logging the data transmission, for example using an asynchronous protocol; -
- Each transmission unit 5 sends a complete protocol of the data transmission to the display signs 3 assigned to it, including possible error messages or the absence of confirmation signals due to failure of a display plate 3, back to the central computer 9.
- the approximate location of the faulty display sign 3 within the sales area can be determined on the basis of the local area which is assigned to the transmission unit which has reported a malfunction of a display sign 3. On the basis of the address of the display plate 3, its position can be determined exactly, so that the display plate 3 concerned can be replaced quickly in the event of a malfunction.
- FIG. 3 shows a top view of an exemplary sales room in which the price information system according to the invention is used.
- the dash-dotted lines identify the different local sections, each of which is assigned to a transmission unit 5. It can be seen that the transmission cones of the antennas of the transmission units 5 are widened oval. Antennas 6 with a corresponding radiation characteristic are to be used for this. If necessary, a plurality of antennas 6 can be connected to a transmission unit 5 for signal transmission to the display signs 3. Alternatively, the local sections can be subdivided further by using additional transmission units 5, so that reliable and fast communication with all areas of the sales area is ensured.
- normal display signs 3 whose display area 1 1 is approximately 50-200 cm 2 in size, can also with special offers, for example at sales tables 13 with special offers considerably larger display signs are used.
- special offer display signs (not shown) can also be provided with more visually conspicuous displays, for example illuminated displays, and optionally have receiving areas for advertising graphics.
- an external power supply can be provided via a power cable.
- Other information than price and product data can also be reproduced on the display surfaces of the display signs themselves.
