Fig. 1 is a schematic block circuit diagram of the present utility model;

Fig. 2 is a signaling circuit diagram of the present utility model;

Fig. 3 is single-chip microcomputer of the present utility model, wireless receiving, language playback circuitry figure.

Operation principle of the present utility model is as follows:

CPU has adopted 8031 stamen sheets in the Single Chip Microcomputer (SCM) system, and EPROM adopts 27256 stamen sheets, and address latch adopts 74LS373, and circuit is simple and clear, P in 8031 interface circuits ₁₀, P ₁₁, P ₁₂, P ₁₃, P ₁₄, P ₁₅, P ₁₆, P ₁₇Respectively with Fig. 2 in P ₁₀, P ₁₁, P ₁₂, P ₁₃, P ₁₄, P ₁₅, P ₁₆, P ₁₇Be connected P ₃₀, P ₃₁, P ₃₂, P ₃₃, P ₃₄Respectively with Fig. 2 in P ₃₀, P ₃₁, P ₃₂, P ₃₃, P ₃₄Be connected, the SP+ among Fig. 2 is connected with SP+ among Fig. 3, and TWH9238 shown in Figure 3 is integrated multichannel remote-control receiving circuit, and 1420 integrated circuits are hard encapsulation audio record circuit.IC ₁Be 4017 decade counters, IC ₃Be 4013, the double D trigger circuit.IC is a communication IC 9114 among Fig. 2.

During circuit working, after at first TWH9238 received triggering signal, the amplification shaping of decoding was at I ₀High trigger signal of data output end output is through Q ₂Amplify drive IC ₃4013 triggers are at IC ₃2 pin output high level, through Q ₂Drive 4N35 photoelectricity corner and close device, this triggering signal is delivered to the P of singlechip CPU ₃₆Interface circuit, telegraph key K ₂Be manual triggers, be 8031 detect signal after, at P ₃₀The output high level is through Q ₈Drive 4N35 photoelectricity corner and close device, close the output of device in the photoelectricity corner, the output high level is through Q ₇Drive, the relay J adhesive, line circuit is just cut signaling circuit, A like this ₁, A ₂Be outside line house lead in, B ₁, B ₂Be user's machine line of being answered the call, the telephone set that the user uses just is connected to this binding post, behind this EO, and the P of CPU ₃₀The output high level pulse, the time should be more than 0.5 second, through Q ₁₃Make 9114 3 pin and the connection of 22 pin, simulate artificial button A.Then CPU is at P ₁₀Export a high level, through Q ₁₄Make 9114 2 pin and the connection of 21 pin, simulation manually connects key 0, and at this moment the telephone number in the 9114 interior storage addresses " 0 " is transfered away, if the telephone set of dialing is just busy, and by electric circuit inspection, as shown in Figure 2, through R ₁, C ₁Q is sent in pulse ₉Amplify and drive Q ₁₀Be electronic switch, by cpu i/f P ₂₂Control is selected when detect external circuit and when is closed the detection external circuit.If need to detect external circuit pulse frequency P this moment ₃₂Pass through Q ₁₁Drive, with Q ₁₀Electronic switch is opened, Q ₉The signal that has amplified is admitted to the photoelectricity corner and closes device 4N35, closes the device output by the photoelectricity corner, through P ₃₃Sending into CPU measures.If it is busy with the road that CPU detects the back, can turn to and dial next alarm call, if after connecting circuit, nobody answers the call, and after CPU waits for a period of time, turns to and dials next phone, the method for dialing next phone is same as described above, P ₃₀The simulation off-hook, P ₃₁Behind the output high level, P ₁₁Be high level, the signaling circuit is sent out and is dialled P ₃₂, P ₃₃Control detection repeats said process.

Behind the required closing of the circuit of dialing, to can hear the warning message of being play in receiver, the 14 pin output by 1420 is through capacitor C ₇Adjustable resistance R ₂, deliver to triode Q ₁Transmitter, C ₇Be capacitance, R ₂Be volume controlling resistance, Q ₁With Q ₂Be combined into electronic switching circuit, 9114 8 pin output high level makes Q during dialing ₂Conducting, collector voltage are zero, like this Q ₁Base voltage is zero, Q ₁End, be turned off by 1420 defeated next speech signals, behind closing of the circuit, when 9114 9 pin became high level, 9114 8 pin changed into low level, and voice signal could pass through switching tube Q ₁, through A ₁, A ₂Send into outside line, the other side could hear warning message in receiver.

P ₃₄Which kind of operating state interface is used for controlling 9114 circuit under, works as P ₃₄When mouth is high level, through Q ₁₂Drive the photoelectricity corner and close device output, 9114 17 pin level are through R ₇Deliver to 9114 9 pin, making 9 pin is high level, and the dial-up circuit quits work, and works as P ₃₄During output low level, 9114 finish the work of transfering of phone.

In circuit shown in Figure 2, D ₁, D ₂, D ₃, D ₄Being bridge rectifier, with the outside line 2W that joins, is the protection voltage-stabiliser tube, R ₆, D ₅Be the power down protection circuit, be connected in the 5V power supply, make 17 pin of 9114 circuit, remain high level, 2W ₂Be 9114 circuit protection voltage-stabiliser tubes, C ₂Being filter capacitor, is 9114 power down at short notice simultaneously, serves as power supply, and because of 9114 when the static state, the power consumption plate is low, Q ₃, Q ₄, Q ₅Be pulse signaling circuit, Q ₃Be the double-tone decoding circuit that takes place frequently, respectively by 10 pin, the output of 11 pin, standard options button K ₁, which kind of send mode control selects.

At 9114 circuit, the external connection keyboard circuit is arranged, occupation mode is the same with common telephone set method with store function, under the circuit preset condition, by 5 keys and corresponding alarm call number, press S key and appropriate address again, just this number is deposited in the appropriate address unit, as store 63882456 can by program, S-6,3,8,8,2,4,5,6 ,-S ,-0, press all keys successively after, 63882456 telephone numbers have just deposited in Unit 0, address and have gone, circuit is simulated when transfering manually by A and 0, and such 63882456 have just transfered away.

The user may feel that the telephone number of depositing is have more than is needed too much in use, in circuit, designs the user and selected the telegraph key group, as shown in Figure 3,8031 interface P ₃₅Be connected in IC ₁4017 14 pin, the interface P of (sending warning message is as the criterion) 8031 after having dialled a phone ₃₅Export a pulse signal, counter IC ₁Write down once, the number of times of record by the output of 2,4,7,10,1,5,6,9 pin, is delivered among the telegraph key group KN respectively, and the user can select dial several phones according to the needs of oneself, as K among the KN ₄Closure, behind intact 4 ones of making call, counter records 4 times, 4017 10 pin output high level is through K ₄Send into Q ₁, through Q ₁High level is input to 8031 9 pin circuit resets, dials and finish, the telephone number that all deposit in also can be a same phone, and user oneself is careless to be set.

Also designed hand-reset key K in the circuit ₁, can carry out hand-reset.

C in the circuit ₂Delay capacitor makes the reset signal of 4017 outputs delay time a period of time C ₄, R ₄Be reset capacitance, resistance, C ₃Be anti-interference capacitor.

1420 is the language playback circuitry in Fig. 3, under preset condition, presses K ₃Can record warning message, be provided with in the circuit and record microphone, K ₁₂Be mode selection switch, can select the periodic duty state, 1420 circuit are recorded and are limited to 20 seconds when the longest, when selecting recurrent state, broadcast capable of circulation is after promptly a segment information finishes, start anew again to play, move in circles, 14 pin SP+ are that the SP+ ' among speech output end and Fig. 2 is close.
