Description

The utility model relates to telephone communications, and more specifically, to machines for rendering paid services with a non-cash form of payment, in particular, to automatic devices of payphones with payment for the provision of communication with a subscriber using payment prepaid cards.

A payphone with an integrated information transmitter connected to a control device that is connected to an information receiver is known, wherein the information receiver and information transmitter are connected to a line, and at an automatic telephone exchange, the information receiver and transmitter are connected to lines, the storage meters are connected to a control unit, with which also connects receivers and information transmitters through controllers (GB, 2184919, Н 04 М 17/00, 1978).

However, this payphone is very complicated, since the control unit serves many lines, is made in the form of a powerful processor, its failure leads to disruption of the entire system.

A payphone is known with a built-in information transmitter, an information receiver, a control device connected to a receiver and an information transmitter that are connected to a line and to an unauthorized connection protection unit installed on a cross-telephone exchange (RU) (RU, 2137317, Н 04 M 17 / 00, 09/10/1999).

The disadvantage of this payphone is its complexity and the inability to use prepaid cards.

The objective of the utility model is to simplify the automatic information communication device, increase the protection of lines from unauthorized connection to them without additional equipment for cross-telephone exchanges by using a prepaid calling card with a bar code.

The technical result is achieved by the fact that the automatic information communication device using a prepaid telephone card with a bar code containing an information transmitter, the output of which is connected to the input of the information receiver, with the input-output of the voice unit and with the line of the automatic telephone exchange, the output of the information receiver is connected to the input of the control unit, the first output of which is connected to another input of the conversational unit, further comprises a scanner, the output of which is connected through the matching unit Kaner to a second input of the control unit, the second and third outputs are connected to respective inputs of a telephone number block access to computer systems and forming unit PIN, whose outputs are connected to respective inputs information transmitter.

The utility model is illustrated by drawings: in Fig. 1, a block diagram of an automatic information communication device using a prepaid telephone card with a bar code is shown; Fig. 2 is a schematic diagram of a telephone card.

An automatic information communication device using a prepaid telephone card with a bar code contains an information transmitter 1, the output of which is connected to a subscriber telephone network and to the input of an information receiver 2, the output of which is connected to the input of the control unit 3, the output of which is connected to the input of the conversational unit 4, the input-output of which is connected to the output of the information transmitter 1, the scanner 5, the output of which is connected to the input of the matching unit of the scanner 6, the output of which is connected to the second input of the control unit 3, the second whose output is connected to the input of the access telephone number generation unit

to computer systems 7, and the third output of the control unit 3 is connected to the input of the PIN code generation unit 8, the output of which is connected to the first input of the information transmitter 1, the second input of which is connected to the output of the telephone number formation unit for access to computer systems 7.

The control unit 3 is made in the form of a microprocessor of type A89C52 with control circuits, the scanner 5 is made in the form of an optical barcode reader of type 1002IR, the block for generating a telephone number for access to computer systems 7 is made in the form of a chip of type K1008VZh18, the block for generating PIN code 8 is made on a memory chip like NM62256.

The telephone card (figure 2) 9 is a rectangle with rounded edges made of hard plastic or laminated cardboard (90 × 60) mm, on one side of which there is a multi-digit card identification number 10 printed by numbers, as well as the card identification number and computer system number, printed with a barcode 11. This information is covered with a protective film 12. Information on the telephone card 9 also prints information of a reference nature 13, which indicates the access code (telephone number) to the computer system 14 and card number 15.

A device for automatic information communication using a prepaid calling card with a bar code works as follows. When the handset 3 is removed on the handset of the device, the control unit 3 turns on the scanner 5 and gives a signal to the talk unit 4 to occupy the subscriber line, upon hearing the “readiness” buzzer from the PBX, the subscriber enters a telephone card into the scanner, from which information encoded by the barcode is read. This information is decoded through the scanner matching unit 6 and fed to the control unit 3, which determines the access code of the computer system in the database that is registered

this phone card. This information is supplied to the unit for generating a telephone number for access to computer systems 7, which generates a telephone number and through the information transmitter 1 issues a line. The PBX makes a connection to the corresponding computer system using this number. After the connection is established, the computer system issues a “receive PIN code” signal. This signal using the information receiver 2 is transmitted to the control unit 3, which through the block forming the PIN code 8 generates a PIN code and through the information transmitter 1 issues it to the line. The computer system identifies the received PIN code if the telephone card on which this PIN code was recorded is recognized as creditworthy, the computer system informs the subscriber (for example, by highlighting the relevant information on the display or by sending a voice message) about the amount (amount of money), corresponding to this card, and asks the subscriber to dial the phone number he needs to communicate with another subscriber. At the same time, complete information about each telephone card is stored in a computer system, and it charges this conversation by comparing it with the data contained in the data bank for this card. At the end of the connection, the amount corresponding to the duration of this conversation is subtracted from the information contained in the database of the computer system, followed by the recording of a new result. If during a call the amount of money on the card reaches zero, the connection is interrupted after the subscriber receives an information message about this. Also, when identifying a telephone card, the computer system will not allow further operation of the device if the card is not creditworthy. By setting restrictions on the PBX to dial numbers from this subscriber set, protection against unauthorized connections is provided.
