Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of Intelligent housing Circuits System, comprise single-chip microcomputer, DTMF decoding circuit, ring detecting circuit and control circuit, single-chip microcomputer connects DTMF decoding circuit, ring detecting circuit, control circuit respectively, plucks/on-hook circuit and ISD2560, control circuit also connects household electrical appliance, and ISD2560 also connects and plucks/on-hook circuit, pluck/on-hook circuit also connects ring detecting circuit, DTMF decoding circuit and telephone line interface respectively, in ring detecting circuit, ringdown is through electric capacity C21, when electric capacity C22 inputs, 75 ± 15V on telephone line, the alternating voltage of 25Hz is through rectifier bridge D4 bridge rectifier, electric capacity C8 filtering, DC voltage after diode D5 voltage stabilizing makes photoelectrical coupler PN817 conducting, the supply voltage of+5V is through photoelectrical coupler PN817, resistance R22 and diode D3 charges to electric capacity C13, when the voltage on electric capacity C13 is charged to the enabling voltage with door F1, with door F1 conducting, simulating signal is converted into digital pulse signal, then the T0 pin being input to AT89C51 single-chip microcomputer counts.
Single-chip microcomputer adopts AT89C51.
DTMF decoding circuit adopts chip MT8870.
Pluck/on-hook circuit employing chip MC1413.
Principle of work of the present utility model is: when user needs to control electrical equipment in family, available handsets or landline telephone dial the telephone number in family, ringdown passes to the phone in family by telephone network, now ring detecting circuit starts to detect ringing signal, one time ringing signal produces a pulse, pulse is delivered in AT89C51 system and is counted, answer there being people or ringing number is not more than 6 times (can by software set) time, control system is thought telephone call signal or maloperation and is failure to actuate, to avoid interference normal telephone operations.When ringing number is greater than 6 times, system thinks the control to socket and electrical equipment, Single-chip Controlling off-hook also starts voice warning circuit and sends prompt tone, require that user inputs password, DTMF decoding chip MT8870 can convert the push button signalling that user inputs to corresponding digital signal, delivers in single-chip microcomputer and judges, if password bad, then voice message is re-entered, and when inputting number of times more than 3 times, system is by automatic hand-up; If input password is after system validation is correct, the numerical key corresponding to voice message user operations, after confirmation has operated, system automatic hand-up.User dials in the process of phone button, and key press time interval can not exceed certain hour (being traditionally arranged to be 5 ~ 10 seconds), and when exceeding setting-up time, system understands automatic hand-up equally.
The CPU (central processing unit) of native system is AT89C51, and all control commands are sent by it, and when after system power-on reset, single-chip microcomputer constantly detects ringdown state.After effective ringdown being detected, start counting procedure, after counting down to setting ring number of times, off hook signal sent by single-chip microcomputer, control circuit automatic off-hook also sends off-hook prompt tone, prompting user inputs password, the simultaneously STD signal sent here of microprocessor detect MT8870, when STD signal is effective, read in instruction code from MT8870 and compare with preset password, inconsistent with regard to automatic hand-up, if consistent, user just further can operate according to the voice message of system, as checked the duty being inserted in electrical equipment on socket, or to the setting etc. of its state.
Ring detecting circuit as shown in Figure 2, when ringdown is through C21, during C22 input, 75 ± 15V on telephone line, the alternating voltage of 25Hz is through D4 bridge rectifier, C8 filtering, DC voltage after D5 voltage stabilizing makes photoelectrical coupler conducting, the supply voltage of+5V is through photoelectrical coupler, R22 and D3 charges to electric capacity C13, when the voltage on electric capacity is charged to the enabling voltage with door F1, with door F1 conducting, simulating signal is converted into digital pulse signal, then the T0 pin being input to AT89C51 single-chip microcomputer counts, each ringing signal produces a pulse, single-chip microcomputer counting once, when counting reaches 6 times, the P2.1 pin of AT89C51 is made to send low level by software, complete off-hook action.
The effect of DTMF decoding circuit is the touch-tone signal that receives from phone input and converts thereof into binary coding, then transport to single-chip microcomputer and carry out data processing, and then realize controlling functions, MT8870 is complete dtmf receiver, can be used as interfacial separation wave filter and digital decoder, filtering part is for changing the height filtering group of electric capacity, demoder is used for digital inquiry, and detect 16 dtmf signals are changed into 4 codes, the minimum value of external counting is preset by three state values of different input amplifiers, clock oscillator and latch.Signal on telephone wire is decoded by MT8870, and telephone dial-up signal is converted into corresponding binary coding, and user is on the keyboard of telephone set after operation push-button, and these information all adopt dual-audio mode to be sent by telephone wire.
ISD2560 supports that user is to the direct address of voice messaging, make deviser need not know its address when operating voice messaging section and voice combine, only need the relative sequence number knowing segment, the operator scheme of ISD2560 is divided into 6 kinds of different patterns according to the low and high level various combination of pin A1 ~ A8, realizes different functions.When starting monitor function, the sound at scene just can be converted to level signal and deliver in telephone line by the level that only need change corresponding mouth, and circuit is simple, easy to use.
Pluck/on-hook circuit as shown in Figure 3, during phone on-hook at ordinary times, two telephone wires are in open-circuit condition, and on line, voltage is added to the ringing circuit two ends of phone, during off-hook ringing circuit disconnect, telephone wire connect.When calling, the High voltage ring signals from telephone wire produces pulse signal through bell flowing detecting circuit, and the P3.5 mouth delivering to single-chip microcomputer carries out ringing pulse counting.When ringing number reaches 6 times, Single Chip Microcomputer (SCM) program control P2.1 mouth exports a low level, then 1 pin that the high level of P2.1 mouth is sent to MC1413 integrated switch driving circuit amplifies, the base stage that high level delivers to triode 9013 is exported by 16 pin, make triode saturation conduction, now, + 5V power supply is through relay coil and triode ground connection, relay coil obtains electric, the electric shock of often opening of relay is closed, closing of the circuit, after user inputs code error or operation terminates, system software controls P2.1 mouth exports a high level, through MC1413 driving circuit, 16 pin output low levels, control 9013 cut-offs, relay coil dead electricity, normally opened contact disconnects, telephone wire is in open-circuit condition again, achieve on-hook.
Control circuit adopts the final control controlling to realize household electrical appliances with the supply socket of relay, such as the electrical equipment of electric cooker, water heater, air-conditioning and so on only need plug in, and namely single-chip microcomputer carrys out the break-make of control apparatus power supply by controlling each relay in socket.
