SU734770A1 - Device for dispensing goods, e.g. of oil products, by credit cards - Google Patents

Description

In such a system, the reliability of the operation of the conflator is not ensured, since there is no operation to control the correctness of reading (| credit from a credit card, its writing to an operative memory).

The aim of the invention is to increase the reliability of the device.

The goal is achieved by the fact that the proposed ycTpoiiCTBO includes a converter, a shift register, an adder, a comparison unit and a credit card stop unit, an output (the information reading unit is connected j through the converter to the register of the scroll register, Oct.1, the output of which is direct, and another through the adder are connected to the comparison unit, the outputs of which are connected to the IDd code comparison unit, and the card stop unit.

The drawing shows a block diagram of the proposed device.

The device contains a blocking unit 1, a card stopping unit. 2, converter 3, shift register 4, adder 5, comparison unit 6, control unit 7, identification code comparison unit 8, line control information unit 9, information receiving and generating unit for perforation 10, unit for registering the distribution of goods 11, unit recording information on a punched tape 12, start-up circuit control unit 13, program block 14, dattik 15 control unit, display unit 16, control unit 17.

The device works as follows.

When you enter a credit card, the read unit 1 reads information line by line from the credit card line by line. Each line-by-line information from the output of the read block 1 is fed in parallel to the converter 3 and the nocTpo4iioro coitrop block. card information 9.

The information read from each line of the gedifit card is controlled by a parameter, for example, evenness, oddness, or other. In case of incorrect reading, the block-by-line information control unit 9 generates a signal that the block of the card 2 triggers and the card passes through the channel lu return The extraneous information in Transformer 3 is converted and entered into shift register 4.

The credit card, besides the information about the owner’s details, also contains the information necessary for identifying the card holder.

A part of the service information carries an additional function to control the correctness of reading and writing to the converter node 3, for example, if information on the arithmetic sum of digital audit information is recorded in the service lines, then the wire is summed line by line when writing to shift register 4, and then comparing this amount with the service information, you can judge the correctness of reading.

The information from the outputs of the first non-service register register 4 is fed to the adder 5, where line-by-line summation is performed. Upon completion of the reading, this amount is compared with the information of the service lines of the card in the comparison unit 6. In case of a mismatch, the comparison unit 6 generates a signal according to which the stop unit of the card 2 is triggered and the card falls to return to the owner. When a match is made, Comparison Unit 6 generates a sirnal, according to which the output of the information of the official cards of the card about the identification code to the comparison block of the identification code 8 of the holder is allowed. The cardholder checks the corresponding keys of the identification code of the control unit 7. The signals are sent to the control unit of the identification code 8 and the control unit 7, according to digital indicators of which the owner judges the correctness of the code entry. Next, the owner presses the start button of the control unit 7.

The signal of the pressed start button in the identification code 8 comparison block generates a comparison signal of the entered identification code of the owner and brand Bbi6paiffloro plv with the corresponding card credit information that goes to the software node 14. The signals from the software block 14 clear the information on the amount of released of oil product 14 and preparation for starting the engine control circuits of the selected fuel dispenser My head, displaying information about the credit card details of the register card ha 4 information reception unit 10 and its perforations 12 in bpokeregistratsii.

Claims (1)

After the registration of information on the puncture is completed, the receiving and shaping unit and the perforation format 10 generates a sigal, so that the card is returned to its owner, i.e., the stop unit 2 is activated and the card is returned. 573 If the recording unit 12 generates a signal of incorrect information, an error signal is transmitted and at the same time program block 14 generates signals to shift register 4 to re-output information to the perforation. The owner of the credit card includes the installation of the distribution of goods and receives the goods The signals from the column sensor come to the registration unit of the quantity of the fired goods 11, where the quantity of the released goods is recorded. At the end of the otousku cardholder turns off the installation. At this moment, the recording unit 11 detects a signal on which information about the quantity of goods sent from it enters the information receiving unit for punching 1O. To eliminate the possible false triggering of the start-up circuit by the signal of the pressed start button of the control unit 7, blocks 8, 14 and 11 turn on the start-up circuit control unit 13, which, by the nature of the initial and final States of the start-up circuit elements, enables the final power element, for example relay. In order to control the signals about the sensor of the installation of distribution of goods during holiday, the sensor is connected to the control unit of the sensor 15. It turns on when the engine is turned on and if after a certain amount of time it does not receive signals from the sensor of the installation, the control unit of the sensor 15 generates a signal display unit 16 for light and sound indications and for alerting maintenance personnel. In the event of the malfunctioning of the registration unit, the control unit 17 generates a signal that arrives at the display unit 16 to alert the maintenance personnel. The proposed device is built on the elements and nodes, mass-produced by the industry, and involves the use of a simple credit card tool. O6 The device allows you to take leave, record and register ||) the amount of top seam by all the columns of the filling station at one ' reader device and one nepiforatora at the gas station. The proposed device allows you to create a unified system of vehicle refueling on credit with an unlimited number of subscribers and a gradual commissioning due to the use of $ 1I in the transition period of the operator's card, according to which the operator can fill up consumers who are not yet secured with a credit card. All the main proposed schematic and structural designs are verified and verified experimentally. The device for draining petroleum products on credit cards has passed departmental tests and continues to operate. Claims An apparatus for dispensing goods, such as petroleum products, by credit cards, contains a block of information reading, a control block whose outputs are connected to an identification code comparison unit, and counters of the quantity of goods released, in order to determine the reliability of the device, it has a converter, a shift register, an adder, a comparison unit and a credit card stop unit, the output of the information reading unit is connected through the converter to the BXOW shift register, one output to orogo directly, and the other - through summatf connected to the comparator unit, the outputs of which are connected to the unit and comparing the identification code of the card unit shutdown.
