Abstract

Quantity recorder of fuel taken from self-service petrol pump in conjunction with a data card, has zeroed and/or set stores (counters) and data transmitter (time, date, quantity, variable and fixed values). Stores and data transmitter interact with a computer in the formation and recording of sums and or balances in magnetic layer fields. The quantity of fuel is printed on coded data cards. To obtain fuel the data card is inserted and automatically read. If the identity number is verified as correct, the value is stored. The new credit is obtained in the computer and recorded on the data card.

Description

Device for the recordable removal, in particular of raw materials at petrol pumps.

The invention relates to a device for recordable Withdrawal, in particular of fuel, from fuel dispensers in connection with data carriers.

There are various methods of self-service at petrol pumps, self-service systems are known in which the self-service access to the fuel pump is regulated by security key or the like and the removed Quantity counted in a special counter activated by the key function will. These special counters are assigned directly to the steering column and during the Counting process mechanically or electro-mechanically coupled. As far as no special, totaling counters assigned to each key are provided, the Capture of the data centrally, on data carriers such as receipts, punched strips, etc. (05 1 800 457, \ 574 028, 1 574 038 and 1 499 498).

In other versions, keys and counters together form one Unit, with self-service at the fuel pump by means of the key function is enabled and at the same time the extracted value is counted from the counter will.

This' value counter or Rert memory is made by adding counting charged and subtractively discharged during the withdrawal process (CH-PS 476 5 and DT-AS 2 046 211).

These solutions are generally very complex and in the scope of the possible number of keys is limited. Especially when collecting the data A data carrier is the evaluation of the data carrier required and therefore costly Facilities required that are only suitable for large tank systems.

The further execution with value storage requires a considerable Expenditure to secure the so-called store of value against influence in fraudulent Intention. Particularly in the case of mechanical execution, there is a considerable effort for the safeguarding of the function and the value memory are thereby locking ring and unwieldy.

The object of the invention is to avoid these disadvantages.

The device for the recordable withdrawal, especially of fuels on petrol pumps in connection with data carriers is characterized by resettable and / or adjustable memories (counters) as well as data transmitters (time, date, quantity, variable and fixed values), which are used with a computer to create sums and / or balances for writing in magnetic layer fields and printing in surface pressure fields of encoded data cards to create a readable acknowledgment of the removal the same work together, with the final balance for storage in the magnetic layer field comes, while in the print field of the data cards the withdrawal and X or end values as well assigned fixed values appear printed out.

The invention thus relates to a device for recording types of data which were used as mobile data storage at the same time. This is what these data cards are for coated with an electronically writable and readable storage medium (e. B.

Magnetic layer field). For the simultaneous creation of a readable receipt the data cards are also provided with a printable data field. In the spec. The data card is used both for drawing off fuel as an authorization card, as well as an Eredit or prepaid card with a predetermined one (entered) monetary value (amount). Each time the card is used to withdraw Fuels will be of value (Price) of the withdrawn fuel from subtracts the value stored (recorded) on the data card and the The remaining balance is saved on the card as a new value.

The same applies to the transfer of a remaining credit to a newly issued one Prepaid card, in addition to its entered monetary value, possible.

In the drawing in FIGS. 1 and 2, for example, the front and back Rear side of such a data card shown, while according to Fig. 3 on the basis of a block diagram the functions are described below.

When fuel is withdrawn, the data card is used by the authorized person inserted into a receiving device 1 and automatically in a reading device 2 had read. If the ident no. correctly recognized 8, the read from the card is Value in a so-called. Buffer 3 given. Together with the information from the withdrawn amount, which is available from the data generator 9, is the test "Credit" of the prepaid card in the arithmetic unit 4 determined on the electronically writable Storage medium rewritten by means of the writing device 12.

The arithmetic unit 4 can be by an electronic computer or can be implemented by a settable counter with read-out connections. This Before the removal of the Fuel on the card read out value is set, and during the refueling process by ongoing subtraction the withdrawn amount is always brought to the (current) still available value. This value can be read out at any time via read-out connections. On the sucked Main memory 5 can both the data determined in the arithmetic unit 4, such as also via the data transmitter 9 the individual information of the refueling process, such as the The quantity withdrawn and the price, both displayed in a data field of view 7, such as also by a printing unit 6 on the intended surface pressure fields of the data card and / or printed on a control strip. About the data transmitter 9 can also fixed values, such as B.

Date and time or a consecutive numbering can be entered. About a special input part "commands" 13 are when issuing new cards the data, such as 3. the value and the identification number. entered or by Commands to the controller 10 together with the balance transfer directly from the old one transferred to the new card. A signal from the error message 11 causes the Process stopped via the controller and the card rejected. Such an error message is recognized in the example shown when the information in the intermediate and Main memory is not correctly and completely recognized. This also includes the code comparison the Identification no. contain.

The positioning of the data card 14 is in the receiving device 1 for writing in the magnetic layer field 15 and for printing in the surface pressure field 16, made in a magnetic layer field.

Claims (10)

Patent claims: S device for recordable removal, esp. of fuels at petrol pumps in connection with data carriers through resettable and / or settable memories (counters) as well as data transmitters (time, Date, quantity, variable and fixed values), which can be calculated with a computer for total and / or Balance formation for writing in magnetic layer fields and printing in surface pressure fields of coded data cards for the creation of a readable acknowledgment of the removal work together on the same. 2. Device according to claim 1, characterized in that in the magnetic layer field the final balance is saved while in the print field of the data cards the withdrawal and / or final values as well as assigned fixed values appear printed out. 3.
