A, when off-premises station presses assignment key, the voltage on AF port 2/7 can be dragged down, Q12 or Q13 in trigger call circuit exports high potential to IC2 single-chip microcomputer;
After B, IC2 microprocessor detect to off-premises station calling, by serial communication and U500 with control the enable audio frequency power amplifier IC3(of I/O port and expand the tinkle of bells and export) and IC4 enter operating state; Open off-premises station power supply circuits output DC13V voltage to power to off-premises station;
C, U500 export music tone ringer and promote loudspeaker J4 sound calling the tinkle of bells to power discharging IC 3 and IC4 after receiving the instruction of IC2 serial ports;
D, off-premises station 1/2 electric after, outputting video signal is input to indoor set video signal control circuit from port 6/10 and carries out channel video signal gating switching controls; The video image display driver circuit outputting to U500 again carries out image display, and display screen is digital high-definition screen.
2), calling is answered: after the utility model called is logical, display screen can show the UI interface of talking state, in machine of the carrying diagram of flicker on direct touch display screen, machine just can directly open voice-frequency telephony and unlock circuit, opens hand-free call in addition and call gating circuit enters and carries out communicating talkback state with off-premises station.
3), unlocking function: machine is entering call in state, can unlock circuit work on enable machine by the icon of unblanking that screen shows, and exports on DC13-14V direct voltage to AF line and carries out unblanking trigging control.
4), call on-hook function: machine was being conversed in interface, can lead to single-chip microcomputer IC2 and send out serial ports instruction and carry out on-hook UI changing interface to U500 display driver circuit, get back on main interface by the on-hook key icon on display screen.
5), touch-screen keypress function: when finger touch is on capacitive touch screen (in UI depicted area), touch-screen can by the I2C interface finger in touch screen interface circuit the location coordinate touched send to IC2 single-chip microcomputer; IC2 single-chip microcomputer carries out corresponding function UI interface display obtained coordinate values by the serial ports U500 chip in image display driver circuit that sends to strictly according to the facts.
6), CCTV function for monitoring: CCTV vision signal is input to CCTV input switch control circuit from J500 interface, and IC2 Single-chip Controlling CCTV input switch control circuit carries out CCTV vision signal gating and controls; Finally CCTV vision signal is delivered in display image driver circuitry U500 and carry out the display of CCTV image procossing.
7), image SD card stores: image press the correspondence image storage key icon in UI interface in illustrated process, and U500 will carry out Image Data Compression the image information of current display by the image encoder of chip internal and be stored in SD card.
8), recall function: when being connected on the switch on S+ and S-on J501 and closing, recall circuit will be triggered and export high level on the detection mouth of IC2 single-chip microcomputer, after microprocessor detect to triggering signal, understand the specific the tinkle of bells of enable ringing circuit sound.
9), multifunction switch function: by the expansion switch UI button in touch display interface, single-chip microcomputer IC2 receives the triggering coordinate of touch screen, send out close display to image crystal drive circuit in U500 chip resolve after, the loopback of expanded function control command to the relay closes in single-chip microcomputer IC2 control expanded function circuit, multifunction switch port S1 and S2 is connected (at ordinary times for often opening).
10), telephony feature:
A, phone are broadcast and are dialed function: machine in main interface, direct pointing telephone machine UI icon; Display interface can be switched to telephone dialing interface; The numerical key can directly pressed on the dialing dish in interface carries out telephone dialing; Single-chip microcomputer IC2 receives after the digital coordinate values U500 chip be transmitted in image display crystal drive circuit that touch-screen sends resolves, show the numerical value of current dialing on a display screen, number numerical value is sent to single-chip microcomputer IC2, single-chip microcomputer is proposed machine sowing number by SPI communication interface to telephony feature module (PH400) circuit and is controlled simultaneously;
B, telephone receiving: after the dialing of telephony feature modular circuit completes, the single audio signal on telephone wire is detected, when detect carried machine by the phone of exhaling time; By SPI communication interface, telephony feature module can inform that single-chip microcomputer (IC2) counterpart telephone carries machine; Now single-chip microcomputer can issue the UI interface switching in image displaying circuit and enter telephone relation intercommunication.Single-chip microcomputer can be opened relevant telephone communicating circuit and enter call state simultaneously, and now phone two ends are even realizes communicating talkback;
C, phone on-hook:
A, the direct on-hook of the utility model machine: by the on-hook button diagram in operation display UI interface, single-chip microcomputer is transmitted to image displaying circuit U500 chip after receiving touch screen coordinate; U500 chip is resolved coordinate, last phone on-hook instruction is sent back to single-chip microcomputer IC2 again, shows UI interface simultaneously and exit phone intercom interface; After single-chip microcomputer receives phone on-hook instruction, closeall communicating talkback passage and telephony feature module, telephone wire enters idle condition; Now remote exchange detects telephony side on-hook, will send the howler tone of single-tone, breaks to catch the opposing party and hang up;
B, exhaled direct on-hook: when the utility model with by calling telephone communication process, exhaled end initiatively on-hook, the telephony feature module in the utility model, by detecting the howler tone on telephone wire, automatically judges whether to be exhaled and holds hanging wire; When telephony feature module detects howler tone signal, telephony feature module can send a signal to single-chip microcomputer (IC2), after IC2 single-chip microcomputer receives signal, notice image driver circuitry is closed telephone relation interface and is got back to main interface standby interface, and closeall communicating talkback passage and telephony feature module, telephone wire enters idle condition;
D, phone called function: when the utility model is by external telephone call, telephony feature modular circuit detects that call bell signal sends to single-chip microcomputer (IC2), after single-chip microcomputer receives telephone call signal, notice image display driver circuit enters phone incoming call display interface, exports the tinkle of bells simultaneously and delivers to ringing tone and power amplifier carries out the tinkle of bells broadcasting.
11), main frame and extension set communication function: main frame and extension set, extension set and extension set, communication between extension set and main frame are carried out the receipts of digital signal by the 12nd and 13 ports of external interface circuit and data communication circuit and sent out; The transmitting-receiving of data is carried out management by main control singlechip (IC2) and is controlled.
Those skilled in the art can make various amendment to this specific embodiment or supplement or adopt similar mode to substitute under the prerequisite without prejudice to principle of the present utility model and essence, but these changes all fall into protection range of the present utility model.Therefore the utility model technical scope is not limited to above-described embodiment.
