SMS: can receive cell broadcast information.Can accept user's information releasing message from the Internet.Has short message prompt function.
Though the domestic intelligent alarm host machine has above-mentioned many tops function, but, when owner stays out, visiting if any the guest, this domestic intelligent alarm host machine can not in time be notified owner with the information of coming to visit, and automatically with dwelling house intercom system and phone UNICOM away from the dwelling house owner, make the visitor can be in time and owner get in touch and link up, the processing relevant issues.
The utility model content
The technical problems to be solved in the utility model is, a kind of intelligent alarm main frame with call forwarding function is provided, when owner stays out, can notify owner with visitor's visiting requirement in time, and the intercom system of dwelling house and the on-site phone of owner or mobile phone connected, make the visitor can be in time and owner get in touch and link up, handle relevant issues.
The technical scheme that the utility model provides is as follows: construct a kind of intelligent alarm main frame with call forwarding function, comprise a kind of domestic intelligent alarm host machine, comprise the master cpu that is arranged on the motherboard, the electrical signal feedback circuit that is connected with master cpu, the electrical signal control circuit, the defence area testing circuit, four watch circuits, keyboard circuit, the telephone network built-up circuit, it is characterized in that, also comprise the calling transfer module that is connected with described master cpu, this module is connected with the talkback circuit of dwelling house, after module is handled detected intercommunication signal, automatically put through the phone that sets by master cpu control telephone network built-up circuit, with the closing of the circuit of talkback circuit and this setting, realize calling transfer.
Implement the intelligent alarm main frame that the utility model provides with call forwarding function, when the visitor calls out owner before the intercom on dwelling house doorway, nobody replys after if the tinkle of bells rings six, can set in advance, then the wired intellective alarm host machine thinks unmanned in the family, just dials pre-set phone, after default phone is put through, alarm host machine makes owner and guest conversation automatically with the door-phone circuit and the connection of dialing.Air time can set up on their own, and after a side was hung up in phone or the doorway machine, alarm host machine was cut off phone automatically, returns to initial condition.Dial is set by the intelligent keyboard of alarm host machine.The utility model can make visitor and owner get in touch and link up in time, handles relevant issues, makes existing alarm host machine have call forwarding function.
Description of drawings
Fig. 1 is the intelligent alarm main machine structure block diagram that the utlity model has call forwarding function;
Fig. 2 is a calling transfer module by signal process chart among Fig. 1;
Fig. 3 is the circuit theory diagrams of calling transfer module among Fig. 1.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, intelligent alarm main frame with call forwarding function is on the basis of former intelligent alarm main frame, realize its call forwarding function function by increasing a calling transfer module 8, a typical calling transfer modular circuit as shown in Figure 3, it is that the integrated package of LM358 and suitable element are formed that module adopts model, the voltage signal of " ding-dong " sound carries out dividing potential drop through the resistance of two 200K, and carry out shaping with the electric capacity of 22Uf, the signal of handling is imported the INA end of LM358, comparative voltage stuck-at-.2V at the NINA of LM358 end, when calling out " ding-dong " sound that produces, the OUTA end output high level of LM358, when not having " ding-dong " sound, the OUTA end output low level of LM358.The multichannel of intelligent alarm main frame selects chip 4051 to be connected with the OUTA end of LM358, and CPU passes through the doorbell signal of 4051 detection of call shift modules, and counts processing.Off hook signal carries out dividing potential drop by 2M and two resistance of 1M, and voltage division signal is imported the INB end of LM358, comparative voltage at the NINB of LM358 end is fixed on 2.5V, OUTB output high level behind the intercom off-hook, when intercom does not have off-hook, the OUTB output low level, CPU selects chip 4051 to be connected with the calling transfer module by multichannel, and detect the OUTB output, and handle according to level signal.Speech processing circuit is connected with telephone network by relay, and speech processing circuit and telephone network disconnect at ordinary times, and when needs were connected with telephone network, the CPU control relay made speech processing circuit be connected with telephone network.By rectifier bridge, will come voice signal to carry out rectification behind the relay, and carry out howling by C2, C3, R3, R4, R5 and handle, and amplify by Q2 then, and be loaded into intercom from telephone network.The voice signal that comes from intercom amplifies back adding telephone network by Q1.
When the people called out owner, the tinkle of bells of intercom rang within six, when CPU detects less than off hook signal, thought that nobody replys, and just by telephone network predefined telephone number was transferred to.Behind closing of the circuit, CPU gives off hook signal of intercom, telephone network and intercom is connected, and simultaneously inside line and outside line are disconnected.After doorway machine or owner's phone were hung up one, CPU control disconnected the calling transfer module, and interior lines are connected, and makes circuit reset.
