(54) DEVICE FOR ACCOUNTING THE COST OF TALKING ON THE SUBSCRIBER TELEPHONE INSTALLATION

The invention relates to radio engineering and can be used to account for the cost of telephone conversations.

A device for recording the cost of a call on a subscriber telephone installation is known, comprising a tariff setting unit, a master oscillator, a divider, a cost counter, a display unit, a power source 1.

However, taking into account the cost of telephone conversations when the rosmash of a known device requires a considerable amount of time.

The purpose of the invention is to reduce the time for recording the cost of telephone calls.

Tsesh is achieved by the fact that the analyzer of the dialed number and the nonvolatile charge are entered into the device. the remembering unit, wherein the input of the ana-

the tariff setting unit with the third divider input, the first divider output being connected to the second control unit input, the third input of which is connected to the first cost counter output, the first input of which is connected to the second divider output, and the second input and. the second output of the cost counter is connected respectively

10 with an output and an input of a non-volatile memory block, the third output of the cost counter is connected to the display unit, the dialed number analyzer contains serially connected serial block, digit determining unit, register and digit counter, the second input of which is connected to the output of the serial block, the display unit contains the connected current service cost meter, the switch, the decoder and the scoreboard, and the current time clock is connected to the second input of the switch.

Figure 1 shows the structural electrical circuit of the proposed device; figure 2 - the same display unit; in FIG. 3 - the same, analyzer 30 of the dialed number. The device contains a tariff unit 1, a master generator 2, a divider 3, a cost counter 4, an indication block 5, a power source b, an analysis, a dialed number 7 jam, a nonvolatile memory block 8, and the display block 5 contains: 9 values of current services , commutator 10, decoder 11, board 12 and clock 1 of the current time, and analyzer 7 dials serial number 14, digit decider 15, register 16 and counter 17 digits. The device works in the following way. When the subscriber picks up the microtelephone and dials the number, the analyzer 7 starts working, fixing both the dialing pulses and their number, the end points of dialing each digit. Analyzer 7 also determines the communication on which the tariff or payment reference number depends, and transmits this information to block 1. After dialing is completed, the moment which the analyzer 7 determines, the master oscillator 2 is started. Pulses from its output arrive at divider 3, controlled by analyzer 7 and 1.. Tariff pulses from the output of the split 3, each of which correspond to one penny of payment, go to counter 4, which transmits information. In block 5, which displays the cost of all telephony calls in rubles and kopecks. At the end of the conversation, the analyzer .7 returns all blocks, except for counter 4, to the initial state. When a voltage is lost for a long time in the line from which the device is powered, the information contained in counter 4 is recorded in a non-volatile memory unit 8 where unlimited time can be stored. When a voltage line appears, which is sufficient for the operation of the device, the information is read into counter 4 and sets it back to its former state. Thus, the cost information is preserved when the supply voltage drops and the device is disconnected from the line. the operation of block 5 and analyzer 7 is as follows. When the handset is placed, the current time is indicated using the clock 13. When the handset is picked up, the switch 10 turns off the clock. board 12 and connect to the decoder 11 counter 9, after having preset it to the zero state. On the indicator board 12, zeros are displayed, and after dialing and the delay expires, the cost of the call begins, as the counter 9 determines the number of pulses from the divider 3. Thus, the subscriber sees the cost of the telephone conversation that he is conducting. At the end of the telephone conversation, the switch 10 again connects the electronic clock 13 to the decoder 11. If it is necessary to obtain information about the total cost of all telephone conversations, the subscriber presses the button 4 on the block 5 and connects the counter 4 through the switch 10 to the decoder 11. The result is an indication of the total 12 cost. After the termination of dialing each digit of the number, the serial block 14 generates a corresponding signal, which in block 15 of the digit determination determines the number of incoming pulses. And the code of this number is written to register 16. Counter 17 reads the number of digits dialed by the subscriber using signals from the end of the digit and depending by VIEW & communication, which is defined in register 16, generates a dial end signal after dialing the corresponding digit. This signal triggers master oscillator 2, divisor 3, and block 9. On the other hand, the code of dialed digits, coming from register 16 to block 1, controls the readout from the last signal corresponding to the tariff of the communication in progress. Thus, the use of the proposed device significantly reduces the time taken into account for the cost of calls. Claim 1.
