Description

(54) IZGROYSTYU FOR DETERMINATION OF THE SUBSCRIBER IN SPARAGE The invention relates to communication technology and can be used in devices for automatically determining the number of the object to be connected and automatic telephone exchanges (PBX). It is known a device for determining the number of a subscriber with paired switching on telephone sets, comprising a matrix scanner, a sensor of different polarity pulses, a power supply unit and linear two-winding relays, one for each subscriber terminal, connected by one output of its windings to the corresponding sensor outputs of different pulse pulses Output to the subscriber line wires, this contacts of the linear two-winding relay are included in the scanner matrix connected to the control unit {1. However, in the known device, it is not possible to determine the telephone number n of the category of the caller, which is necessary, for example, to charge for a long-distance call. The purpose of the newbing is to provide an individual account of telephone conversations. This is achieved by inserting control relays and the OR element, nrn-4, than one winding of the control relay, connected to one pole of the power supply unit, and the other output to the corresponding input of the sensor. This horizontal matrix of the scanner is connected to the inputs of the OR element, the outputs of which are connected to the control unit through the contacts of the control relay. The drawing shows a structural electrical circuit of the proposed device. The device for determining the caller's number when paired switching on the telephone sets 1 and 2 contains a matrix scanner 3, sensor 4, different-polarity pulses, power supply unit 5 and linear two-winding relays 6, one for each subscriber line, connected by one output of its windings to the corresponding sensor outputs 4 rasnopololnyh pulses, and other conclusions - to the wires of the subscriber line, while the contacts of the linear two-winding relay 6 are included in the matrix of the scanner 3 connected to the control unit 7, controlling p le 8 and the element

OR 9, and the winding of the control relay 8 is connected by one output to one pole of power supply 5, and the other output - to the corresponding input of sensor 4 of different polarity pulses, while the horizontal lines of the scanner 3 are connected to the inputs of the OR 9 element, which outputs a switching relay 8 is connected to the control unit 7. The linear relay 6 and the scanner matrix 3 can be combined in total on both contacts and contactless elements, for example, on ferrods, on semiconductors, or on optocouplers.

The device will melt as follows.

In the slow state in telephone sets}, the 2 loop is open and therefore the windings of the linear two-winding relay 6 are inadequate.

When you snoop from the telephone I (2), the linear dynamic memory relay 6 operates and closes a corresponding contact in the scanner matrix 3. The closed contact of the sensor 6 of the scannary matrix 3 of the scanner matrix 3 can be read in block 7 from the vertical from the vertical to the element OR 9, as well as from eurshkali — through the element OR 9. The received P {W by this control unit 7 of information is sufficient only for determining the line of the internal line and for checking the correctness of the contour lines. Recognition of which of the two telephone contacts 2 or 2 is calling is provided by a signal coming through the contact of the control relay 8 to the baking terminal 7 of the control.

The control unit 7 p {shmet either lot 1 or logical O, depending on the contact state of the control relay 8, depending on the polar potentials applied to the winding of the linear relay 6.

Since lifting a tube from a paired telephone set 1 or 2 can cause linear relay 6 to operate only at a certain polarity (phase) of power supply unit 5, the signal received by control unit 7 via control relay contacts 8 unambiguously determines which of the two telephone sets is defiant.
