Now in conjunction with the accompanying drawings specific design of the present utility model and operation principle are described further:
Fig. 1: the operation principle block diagram of the utility model device
Fig. 2: off-hook ring detecting circuit figure
Fig. 3: serial matrix form keyboard scan circuit diagram
Fig. 4: display interface device circuit diagram
Among Fig. 1, what dotted line was above is control service area, and following is permanent service area, and purpose is in order to reduce power consumption.Microcontroller adopts the Z86E08 single-chip microcomputer of the one-off programming memory with 2K byte, and 124 byte general registers wherein and 4 byte I/O registers all can be used as accumulator and use, and the test function that 14 spendable I/O lines are finished to be needed can be provided.Whole device comprises that microcontroller (1), keyboard (2), display (3), memory (4), serial line interface (5), sound circuit (6), dial-up circuit (7), decoding circuit (8), simulation pluck/on-hook circuit (14), off-hook ring detecting circuit (15), power supply (11), power control logic circuit (13).Microcontroller (1) is according to the key entry value control dial-up circuit (3) of keyboard (2), and according to playing needs control sound circuit (6), output signal is transferred on the telephone wire through driving amplifying circuit (9); The serial line interface (5) that is provided with is in order to make the middle data of other controller readable and writable memory (4) to realize initialization, input or the rewriting of telephone number; Microcontroller (1) is controlled the line and the alignment of calculator keyboard by inner display interface circuit, thereby reaches the control to display (3).
Fig. 2, under the control of power logic control circuit (13), device is in the stand-by operation state at ordinary times, and power supply (11) is only given the power supply of permanent service area, and static power consumption is considerably less, and the circuit of other control service area does not power on.Have only when user's off-hook or outside line ring, the off-hook ring detecting circuit is started working, and photoelectric coupling circuit o1, o2 wherein has at least one to be in conducting state, by differential circuit C
1-R
3U at the R-S trigger
l-A/1 produces a pulse signal, makes control service area get electric work by the power control logic circuit.Microcontroller sends an automatic off signal POFF after executing the task of appointment, by the power supply of power control logic circuitry cuts control service area.When needing, can if there is not operation after 20 seconds, then shut down automatically by the power supply state of manual open and close button (16), (12) control service area.
UKC1 among Fig. 3 (74HC164), UKL1 (74HC165) are respectively to seal in and go out and incorporate into and go here and there out integrated circuit, are used for serial signal is converted to parallel signal or parallel signal is converted to serial signal.Keyboard is incorporated into and is gone here and there out the emitter junction J ground connection of each incoming line by the BGK1 of row resistance R MK1～RMK2 and triode of circuit.So they are low level at ordinary times, and the input state line is a high level.During keyboard scan, send undersuing to arrive KINCL and KOTCLK earlier, make and respectively scan output line and be low level.Then with KOD﹠amp; IL places 1, send a negative pulse to KOTCLK, at this moment the Q of UKC1
0Be output as high level, send a negative pulse to KOD﹠amp; IL, with scanning incoming line state latch to and series-in-series-out register in.When these row of UKC1 do not have key and press down, each incoming line and condition line are kept original level, if this is shown a key and presses, then making corresponding incoming line is high level (other incoming lines keep low level because of the clamping action of BGK1 emitter junction), and to make condition line be low level.Read Q by KINDT
1If, 0, illustrate that this shows key and press, then send the KINCLK negative pulse continuously and read signal, up to being to obtain the row at button place at 1 o'clock, thereby try to achieve key assignments; If 1, illustrate that this is listed as no key and presses, then with KOD﹠amp; Send a negative pulse to KOTCLK after the IL zero setting again.This moment, high level was displaced to the Q of UKC1
1, and the Q of UKC1
2Become low level.Identical with the mode of checking previous column, again these row are checked that to the last the no key of row is pressed, and then advances next circulation, then enters corresponding processing program when having key to press.What of keyboard row, column number can be selected (for effectively utilizing integrated circuit, generally selecting 8 multiple) as required, determine the number of 74HC164 then according to columns, determine the number of 74HC165 to make keyboard be convenient to design and expansion according to line number.
UD0 among Fig. 4, UD1, UD2 have constituted the interface circuit of LCD, and wherein UD0 is for sealing in and go out integrated circuit 74HC164, and UD1, UD2 eight select an analog switch MC4501B.The INH of MC5401B is for forbidding end, and when it was high level, switch disconnected, and during for low level, the X end is according to input selecting side A, B, the value of C and a connection among X0～X7.In this circuit, the output of UD0 is received in the input selecting side of UD1 and UD2, and their X is connected together, and X0～X7 connects the line of calculator keyboard respectively, with the action of moving back disconnected simulating keyboard of simulation switch, thereby cls and the digital demonstration of finishing display wait operation.
Now function and the using method with the utility model device is described below:
The user picks up mobile phone or by the start button, device powers up work and carries out keyboard scan, carries out corresponding work according to button.
One, one touch dialing:
1, speed dialling: click the button of representing certain unit or individual, device can be transferred to telephone number corresponding according to button.
2, automatic number picked up: if button is empty, then enter the number picked up state automatically, prompting Enters Number, and the back of being totally lost is by definite key, and then this number deposits corresponding units in, enters fast group state, presses cancel key, end operation.
Two, redial automatically:
Behind the Outgoing Call number,, can enter the state that redials automatically by automatic redial key if the other side is busy or nobody connects.1) simulation on-hook: simulate on-hook then, behind the wait dialing tone, the re-dialing telephone number.2), check the circuit sound:, return state 1) if when busy.3), if the circuit sound not for busy, is sent out prompt tone, wait conversation back shutdown.
Three, number administration:
The number editor: after pressing editing key, key according to number again, then demonstrate original number after, wait for and revising.Revised the back by determining key, number deposits corresponding units in, presses cancel key, end operation.
Four, informing function:
1, connects and to know key is set that order shows the number of former setting.The number that can press the unit of answering when needing to revise is then by cancellation or definite key.Key as per advice is set after all being totally lost again, end is set.
2, record button as per advice enters recording state.
3, playback button as per advice enters tone playing state.
4, key as per advice enters the circulation notify status.
5, check key as per advice, order shows the number of not putting through.
Five, number unloading:
When needing, unit can arrange a phone as the number administration machine.Behind the number of the basic directory of unit batch modification, the number after supervisor can be changed the phone unloading of registering.Its process is: after the outside line ring, the device Auto Power On is checked to have or not the number unloading command, if have and then simulate the new change number that the receiving management machine sends behind the off-hook, and the corresponding units among the EEPROM revised, feed back into function signal to supervisor after finishing, then shutdown.
The utility model is compared with prior art, and is multiple functional, almost related to telephonic communication The middle most problems that occurs, simple to operate, quick, can greatly increase work efficiency, improve Use level and administrative structure, cheap, be easy to commercialization, any person of needs is equipped with Rise. Be worth in industries such as the busy department of big unit and talk business or administration, cause, commerce Vigorously promote the use, have wide market application foreground.
