Abstract

A kind of telephone set time-counting device, it shows the moment of normal time when off-hook not, show call timers behind the off-hook, and according to dialed number, talk times is accumulated to international long-distance respectively, in national distance and the city stored count device.The moment that the user can show with button inquiry talk times and adjustment display at any time.

Description

Chronometric and counting device for telephone set

The present invention is used for the time of headphone conversation and the device of number of times.

In recent years, developed and used the electronic clock that is fitted together with phone.But it is just identical with general time clock feature.Also have a kind of and telephone set coupling counter it can only write down each air time and convert thereof into number of times and represent.In addition, also has a kind of multi-function telephones meter made from single-chip microcomputer.But its cost height.Being not suitable for numerous telephone subscribers uses.

The purpose of this invention is to provide a kind of time-counting device that can show constantly again energy measurement air time and accumulative total talk times.

Along with the development of extensive and very lagre scale integrated circuit (VLSIC) can be integrated in the circuit of above-mentioned functions of the present invention on the chip, can reduce cost greatly.Reduce volume.

The object of the present invention is achieved like this.On the telephone set card, press device, display.Indicator light and one group of five button, they all link with circuit.Circuit is installed in the telephone casing.When the user does not make a phone call, when promptly not plucking microphone, display shows the moment of normal time, makes clock and uses.When the user makes a phone call, take microphone, conversation is Once you begin.Telephone set card display promptly shows call timers, and carries out stored count when showing call timers.The present invention judges the different regions talk times according to the front two number of dialing, if the anteposition number all is zero; Or only first be zero; Or the front two number is not zero, distinguishes international long-distance.The number of times of national distance and local traffic.The user can press corresponding button at any time and carry out the world, and is domestic.The inquiry of local connection number of times.And the check and correction that shows the moment.

Describe embodiments of the invention and working condition in detail below in conjunction with accompanying drawing.

Fig. 1 is the outside drawing of the specific embodiment of the invention;

Fig. 2 is a general principles block diagram of the present invention;

The telephone set watch face that Fig. 1 is according to the present invention to be done.Microphone 1 is not pressed on the take-up switch 6 the normal moment of display 2 read clocks during off-hook.Making a phone call, microphone 1 leaves take-up switch 6 behind the off-hook, take-up switch 6 lifts, at this moment provide an off-hook control signal, cooperate internal circuit to open time meter and count circuit 15, select different stored count circuit according to the front two number that telephone set watch face numerical key 5 is transferred to, if the front two number all is zero, then select international long-distance stored count circuit 20; If only the first figure place sign indicating number is zero, then select national distance stored count 21; If preceding two numbers are all non-vanishing, then select city stored count circuit 22.Time meter is counted circuit 15 and by decoder driver circuit 17 and display circuit 18 the measured time is shown by display 2 on the one hand, on the other hand the Measuring Time result is delivered to accumulative total memory in the selecteed stored count circuit.

K1 K2 K3 K4 K5 in one group of button 4 of phone card.Be that for convenience the user can inquire about the different regions talk times at any time, the shown clock of check and correction display 2 constantly, and to the zero clearing of stored count circuit.Indicator light 3 is lighted when the zero clearing of stored count circuit and is used for pointing out the user to note.

Fig. 2 has provided principle of the invention block diagram, below in conjunction with Fig. 2 this circuit theory is described in detail.

Do not make a phone call.Clock when putting down microphone 1 and meeting the other side normally walking of showing when calling, it is by crystal oscillating circuit 7, frequency dividing circuit 8.School parallel circuit 13 during the school, clock counting circuit 14.Decoder driver circuit 17, display circuit 18 and display 2 are realized jointly.Showing when undesired as clock can be by a second nulling circuit 9, school parallel circuit 13 and proofreading fast when sequence circuit 10 and school during the school.Check and correction constantly, the time digital flicker school divide the time-division flicker to be used for pointing out the user.

Make a phone call to hang on 1, begin dialing by keyboard 5, display begins to show call timers after the other side connects phone.This function is by display mode control circuit 16, and control circuit 12 during survey.Time meter is counted circuit 15, decoder driver circuit 17.Display circuit 18 and display 2 are realized jointly: understand this for the convenience of the user and converse the used time.Postpone one demonstration period when having made a call after putting back to microphone 1, again time meter is counted circuit 15 automatic clears.Get back to the clock show state simultaneously.

The present invention adds up talk times when showing call timers.This function is by display mode control circuit 16.Stored count channel selection circuit 23.Stored count circuit 20.21.22. decoder driver circuit 17 display circuits 8 and display 2 are finished.Stored count channel selection circuit 23 is to select according to the front two number that numerical key 5 is dialled the number.The front two number all is the international stored count circuit 20 of zero option; Preceding one digit number sign indicating number is the domestic stored count circuit 21 of zero option; The all non-vanishing selection of front two number city stored count circuit 22.The user at any time can be international by button K1.K2.K3. inquiry. and domestic. the local telephone talk times.Above-mentionedly can postpone all to show that a period of time returns the read clock state.Need the time recording number of times of making a phone call as the user.Behind the record data, zero clearing can be finished by button K4.K5. and stored count clear circuit 11, and simultaneously indicator light 3 is noted to user prompt.

After the discharge words, the time-delay of asking when the time-delay of demonstration time and stored count show during survey is that shared same delay circuit (not making) is finished.

More than several function displays by scanning sequence circuit 19, decoder driver circuit 17.Display circuit 18 and display 2 are realized.

Noted earlierly only limit to a kind of example of specifically executing of the present invention.But obviously.Can make various changes and improvement to this invention.To realize part or all of function of the present invention.
