When " sleep set " when key is pressed, alarm clock can show and carry out the default quarter-bell length of one's sleep (to be preset eight hours when dispatching from the factory, the user can be after sleep setting button be pressed, revise and store the new default length of one's sleep by mode) by "+"/"-" key, this time is the quarter-bell time of the former setting of displacement automatically, the setup unit length of one's sleep 6 of countdown is simultaneously set the length of one's sleep by the mode of countdown, and after countdown came into operation, quarter-bell will be triggered when the time expires.This sleep alarm promptly is not to set a fixing quarter-bell time, but sets a fixing length of one's sleep for the user provides a new quarter-bell time set mode.This function is particularly suitable for a certain specific date, for example uses when weekend, because second day of weekend need not to get up in the set time usually, this simple and easy function can guarantee that the user has enough lengths of one's sleep.In order to be fit to the situation that this " once in a while " uses, this is disposable with replacing the former quarter-bell time length of one's sleep, and promptly after the sleep quarter-bell finished, the quarter-bell time originally can recover automatically.

Also has other one group of label on above-mentioned five buttons (" day settings ", " time set ", " sleep is set ", " quarter-bell setting ", " the tinkle of bells setting ") side, be respectively " Qianmen ", " garage " " master room ", " kitchen ", " children room ", this is called as " extension set title " in an embodiment of the present invention, and pairing button then is referred to as " extension set button ".The embodiment of the invention has the speech talkback function of a networking, so-called networked speech talkback, be meant and between a plurality of (two or more) alarm clock, realize addressable unidirectional or two-way call, because one-way traffic is a special case of two-way call, will be primarily aimed at two-way call in the embodiment of the invention and launches to describe.Above-mentioned " extension set title " is a kind of appellation of embodiment of the invention when digital alarm clock is used as an intercommunication extension set, the network digital alarm clock that is placed on master room is called as " master room " extension set, then is called " master room " extension set button with the corresponding button of master room extension set.Above-mentioned five extension set buttons also respectively corresponding five arabic numeral (being respectively " 1. "-" 5. "), these numerals are called as " extension " in the present invention, these extensions can occur in display screen when intercommunication is called out, and make the user know the extension of calling party.

Five above-mentioned buttons use jointly by alarm clock function and intercommunication function (be designated hereinafter simply as " multiplexing ", at a time which kind of function these buttons represent, and are decided by " functional select switch " on the alarm clock.Functional select switch in the embodiment of the invention has three kinds of patterns, is respectively " radio reception ", " alarm clock " and " intercommunication ".When functional select switch was set in " alarm clock " position, these five buttons were exactly the alarm clock button, and when functional select switch was set in " intercommunication " position, these five buttons then were " the extension set buttons " of intercommunication.Then can make digital alarm clock enter the radio state as for " radio reception " pattern, five above-mentioned buttons have become wireless " channel predetermined " button again, can make the usefulness of one-touch radio reception channel selection (channel selection).If these five channel predetermined all is not suitable for, then can be by "+"/"-" button channel selection, after required radio station is chosen,, become " channel predetermined " in the future just longly can store this new station channel by a certain channel predetermined button.

In addition two other intercommunication function button multiplexing: " global call/intercommunication " key and " specific call/intercommunication " key with alarm clock function.In the intercommunication pattern, press " global call/intercommunication " key, can realize that all other alarm clocks (intercommunication extension set) in this alarm clock and the system carry out speech talkback; And press " specific call/intercommunication " key, can realize that then this alarm clock and called specific alarm clock (intercommunication extension set) carry out speech talkback.Selected extension set has two methods, and method one is the specific extension set button of flicking a certain (or a plurality of), and then by calling/intercom push key, and such one (or a plurality of) specific extension set is just chosen; The method of another selected extension set (method two) is long by (above two seconds) a certain specific extension set button, and need not again by " specific call/intercommunication " key.Method two fairly simple (only needing) by a button, but an extension set once can only be selected.Calling out with intercommunication is two different mode of operations in embodiments of the present invention, initiate an intercommunication if adopt the calling form, the automatic jingle bell of then called minute chance has only when being called out and just can carry out intercommunication after extension set is responded (pressing calling/intercommunication key of being called out extension set); And initiate an intercommunication with the intercommunication form, then being called out extension set can jingle bell, but directly listens to from the cry (speech) of initiating extension set." calling/intercommunication " here is a multiplexing key, and flicking is " calling ", and be long by being " intercommunication ".The notion of calling out only is suitable for when initiating an intercommunication in the present invention, the notion of " calling " is just no longer suitable after the conversation beginning, at this moment " calling/intercommunication " button will only use as " intercommunication " key, promptly push button to the other side's speech (entering sending mode), unclamp button and listen to the other side's sound (entering listen mode), the using method of this and traditional intercom is consistent.In " global call/intercommunication " pattern, all extension sets all can jingle bell (when being called out) or hear cry (during intercommunication) from the promoter, unless a certain extension set is in mute state.When a certain specific extension will be replied, can by " overall intercommunication " key and " specific intercommunication ", all extension sets can both be heard answer when different was by " overall intercommunication ", then have only the promoter can hear answer during by " specific intercommunication ", this function can be given the user one and be selected flexibly.

In above-mentioned example, nearly all function button all is multiplexing, and promptly alarm clock, radio reception and three kinds of mode commons of intercommunication one overlap button, and the operation push-button on the panel can seem more succinct like this, and button resources can obtain utilizing more fully.In order to realize radio reception and intercommunication function, the embodiment of the invention has also comprised a loudspeaker and a microphone, and this loudspeaker also is the part of alarm clock function, can realize radio quarter-bell and default music quarter-bell, and this has further expanded the function of alarm clock.

Please refer to shown in Figure 5, in the centre position of Fig. 5 is a processor 1, this is the control core of embodiment of the invention network digital alarm clock, bear button input detection, sensor input detection, functional select switch detection, and the transmitting-receiving of digital signal, the input of quartz crystal oscillator and the functions such as output of displaying contents.In embodiments of the present invention, quartz crystal oscillator is the time signal source of alarm clock, and processor is a time counter, and all dates, time, quarter-bell, sleep are set, and the intercommunication extension set selects, sends intercommunication calling or conversation etc., all is that the control by processor realizes.Also realize/embody at remote control command recognition unit 11 described in Fig. 2 and Long-distance Control performance element 12 by processor 1, this includes two kinds of situations, first kind of situation is when local keys of key or sensor input, processor 1 carries out detection and Identification to it, and, send corresponding order to realize described Long-distance Control by Control Network interface 4 then according to the remote control command that the situation affirmation that is detected will be carried out; And second kind of situation is, this alarm clock is as the second network alarm clock, processor 1 receives the remote control command of the first network alarm clock by Control Network interface 4, and this order discerned, relevant with this alarm clock if (for example destination address (being controlling object) conforms to self), then processor 1 can be implemented local control by connected local control device, to realize the remote control function of first network alarm clock expectation.The multiplexing of clock and intercom push key also is to be controlled according to the state (position) of functional select switch by processor 1, the time that processor 1 is also pressed according to button judges that flicking (being less than two seconds) is still long by (greater than two seconds), to realize more button multiplexing function.In this figure, do not mention function of radio receiver, will discuss in the relevant below chart with intercommunication function as for more radio reception.

Please refer to shown in Figure 6ly, the signal that the embodiment of the invention sent has two kinds, and a kind of is audio analog signals from microphone; Another kind is exactly the control figure signal of from processor 1, comprises scale-of-two control routines (hereinafter to be referred as data) such as address code, order code and parameter.In Fig. 6, simulating signal and digital signal are that (simulating signal is by first carrier modulator 41a and first carrier detuner 44a in separate modulation/demodulation, digital signal is by the second carrier modulator 41b and the second carrier wave demodulation device 44b), and independent transmissions/reception (simulating signal is passed through first carrier transmitter 42a and first carrier receiver 43a, digital signal is by the second carrier wave transmitter 42b and the second carrier wave receiver 43b), that is to say that simulating signal and digital signal have different signalling channels, different signal modulation systems, even (in actual applications with different signal transmission media, also make simulating signal use identical modulator with digital signal, transmitter, receiver and detuner have more detailed description among Fig. 8 that this will be below and Fig. 9).The most common signal transmission medium is air (transmitting and receiving radio wave signal by antenna) and line of electric force (coming transmission signals by power line carrier).As for selecting for use which kind of transmission medium will depend on the frequency of signal transmission and the classification of transmission/reception coupling mechanism.In practice, high frequency radio signal (＞=30MHz) can adopt antenna emission/reception usually, the low frequency radio signal (＜30MHz) then transmit by power line carrier.Modulation system as for signal, simulating signal AM commonly used and FM, and digital signal is except that AM/FM, can also use on-off keying (On-OffKeying, OOK), frequency shift keying (Frequency-Shift Keying, FSK), (Phase-ShiftKeying PSK) waits the digital switch modulation to phase-shift keying (PSK).Transmission for digital signal also will be selected certain communication protocol for use usually, with the transmission and the reception of coordination signal, and realizes the effective reduction of control signal and the correct execution of steering order.

Wireless control network commonly used has Zigbee, Z-Wave, INSTEON etc., power line carrier Control Network commonly used then has universal electric power line carrier wave bus (Universal Powerline Bus, UPB), E-consumer bus (Consumer Electronic Bus, and X10 and LonWorks etc. CEBUS).Except that above-mentioned Control Network, on market, also have various self-defining network interfaces, the present invention does not get rid of any Control Network interface, as long as can make the long-range control function of realization on the alarm clock.Control Network is the optimal selection that the present invention realizes networked Long-distance Control, can systemic-function is decentralized because networking means, the different place of system can be put/be installed in to the sensor, controller and the actuator that promptly are a control system, and can increase and decrease as required.The network digital alarm clock of the embodiment of the invention both can be played the part of the role of controller in system, the role that also can play the part of sensor and actuator, depend on the setting of remote functionality modules configured and remote control command on the alarm clock and decide, details can be with reference to table 2 described later.

Please refer to shown in Figure 7, be connected with processor 1 except the digital signal sending and receiving device, also has a storer 2, be used to deposit the relevant set information of alarm clock system, comprise this address code (source address), controlling object address code (destination address) etc., wherein the controlling object address can be the address of intercommunication extension set, can also is the address of sensors such as security protection, temperature by the address of equipment such as control door lock, light, electrical equipment also.Equipment such as above-mentioned door lock, light, electrical equipment can be one independently with the equipment of network alarm clock system compatible, also can depend on the network alarm clock, by the directly actuated equipment of network alarm clock processor.What provide in embodiments of the present invention is to control at the equipment that depends on the network alarm clock, therefore in fact described controlling object address is exactly the address of telecommunication network alarm clock, is the same as for the situation of sensors such as security protection, temperature and the situation of above-mentioned opertaing device.In a network system, implement control to a certain particular target device, must provide correct address code, otherwise just can not cause the concern of target device.Similarly, in a two-way control (for example intercommunication) or need in the system of feedback of status, the equipment that sends steering order also will carry the address code of self, makes target device can know the source of control signal, and as the target of feedback of status.In intercom system, the extension that the branch chance that receives call signal will be sent call signal is presented on the display screen, and it is who is calling out that the user can be known, this is similar with incoming call display function in the telephone system.Because the phase related control information and the parameter of system can be set by the user; and require the setting of these information can not lose because of power down; therefore storer can use usually EEPROM (Electrically Erasable Programmable Read Only Memo) (Electrically Erasable Programmable Read-Only Memory, EEPROM), nonvolatile memory IC such as FLASH storer.

One group of input equipment and one group of output device in addition of being connected with processor 1 in addition.In input equipment, except that the existing specific keys input of describing before, also have the input of some sensors, comprise security sensor (sensors such as for example infrared, door magnetic, window magnetic, glass, coal gas, fire, water logging) and parameter sensors (comprising sensors such as temperature, humidity, brightness, pressure).Wherein specific keys input and security sensor trigger the transmission that all may cause a control signal, for example cause call/intercommunication, or initiatively security alarm once, this will depend on system's setting at that time, for example whether system is in the intercommunication state, whether communication channel is idle, and whether system is in the state of deploying troops on garrison duty etc.As for parameter sensors, except that doing local alarm clock use, (for example in the alarm clock display screen, show local temperature), also can make the usefulness of long-range remote sensing, for example when other telecommunication network alarm clock requires to read temperature, return detected temperature value to this telecommunication network alarm clock.In embodiments of the present invention, input equipment also comprises a phone induction installation, this mainly is whether the telephone set that is connected with alarm clock of induction is at off hook state, if and channel also in idle condition, the voice that then can initiate a phone connect, promptly at first pass through a telephone connecting device (linking to each other) of Control Network interface 4 gating far-ends with a telephone wire, and then be communicated with the voice channel of these telephone connecting devices by voice communication interface 5, so just equaled to be communicated with being connected of local exchange switch and remote phone line.So just can expand the access of telephone set with wireless mode (or power line carrier mode), particularly not have the room of telephone wire to realize that telephone set is connected with the virtual of telephone wire at some.

Analyze the output device function that is connected with processor 1 below.In these output devices, include five control device, be respectively controller for telephone, Light Control Unit, microphone control device, electronic lock control device, loudspeaker controller.Wherein controller for telephone and above-mentioned phone induction installation are corresponding, but it then is opposite that control flows to, mainly when telephone wire has an incoming call to enter, can activate local telephone ring signal by the remote phone coupling arrangement, make the ringing telephone stations that links to each other with alarm clock, and behind the telephone set off-hook, be communicated with the voice channel of remote phone coupling arrangement, realize that local call is connected with the audio frequency of remote phone line.

As for microphone control device and loudspeaker controller, mainly be the connected state that is used for controlling voice analog signal.Monitoring when local unit is required (for example to send the remote monitoring order by the telecommunication network alarm clock, this has associated description in aftermentioned table 2) and when being allowed to (can select in this locality monitor to allow or monitor shielding), the sound signal of microphone just is communicated with analog carrier modulation channels and simulating signal transmitter, and modulated sound signal is sent to the function that remote monitoring is realized in the unit (for example other telecommunication network alarm clock) that requires monitoring in the network.Similarly when the intercommunication function pattern, the microphone control device also can be communicated with or shield as required, to realize the control of audio stream, is similar to above-mentioned snoop procedure.As for loudspeaker controller also opening or closing of control loudspeaker as required then, realize the broadcast of audio frequency or quiet.Two other output-controlling device can directly connect controlled equipment, the light fixture of Light Control Unit join dependency (can drive) for example by relay or controllable silicon, the electronic lock control device connects electronic lock (also being to drive by relay or transistor/field effect transistor) etc., to carry out the remote control command that remote equipment sends in this locality, realize the control of described " getting up in the night to urinate " light, and long-range functions such as " unblanking ".Except that above-mentioned example, can also on the network alarm clock, connect more local opertaing device, to realize the more control function,, just repeat no more here because principle all is the same.

Except that the above-mentioned control input and control output function that can see, in Fig. 7, in fact also comprise the remote control function that some be can't see, for example synchronous the and long-range quarter-bell synchronizing function of remote time.Because these synchronizing functions are processor 1 inner the realization, so these two functions just do not draw in Fig. 7.Its specific implementation method is, when processor 1 is received remote synchronization order (relevant description is arranged) from other telecommunication network alarm clock in aftermentioned table 2 after, with received invest in the remote synchronization order time/original time of quarter-bell information displacement self/quarter-bell information, thereby the remote synchronization of realization time and quarter-bell.

Please refer to shown in Figure 8, in Fig. 6 before, analyzed a signal transmission and reception theory diagram among the embodiment with general characteristic, here then introduce the best communication interface embodiment among the embodiment, the greatest feature of this scheme is the synchronous transmission that can realize sound signal and digital signal, this technology has further been simplified the circuit of system, has also reduced the cost of system simultaneously effectively.Can see the signal that all will send among Fig. 8, comprise from the audio analog signals of phone/microphone and the control figure signal of from processor, these signals all are sent to same carrier modulator modulation, in embodiments of the present invention, carrier modulator adopts voltage controlled oscillator, realize the modulation of simulating signal and sound signal by the modulation system of FM, produce a unified modulated carrier signal (hereinafter to be referred as compound FM signal), send by transmitter and transmitting antenna then and (can adopt different frequency ranges with market according to different countries, citizen's frequency range (CityBand for example, CB), family wireless electricity service (Family Radio Service, FRS) frequency range, the radio microphone frequency range, public's intercommunication frequency range, wireless phone frequency range etc., or in line of electric force, send by transmitter and coupling mechanism, can adopt the low-frequency range of 100-500KHz on the frequency, perhaps with 6.78M, 13.56M, 27.12M, 40.68M (Hz) be the industry of centre frequency, science, medical science frequency range (Industrial, Scientific and Medical, ISM) etc.

The phone simulating signal can be earlier by relevant control device before inserting voltage controlled oscillator with the microphone simulating signal, the existing description in this relevant in the above paragraph.Then can before entering voltage controlled oscillator, carry out a low frequency carrier signal modulation earlier as for digital signal, and this carrier wave is a low frequency signal (for an aforesaid FM modulating frequency), its highest frequency is to be no more than the treatable frequency of FM demodulator described later degree of being, the practice on 19KHz or near frequency be the best, because this frequency both had been within the output signal bandwidth of conventional FM demodulator, can not amplify with Play System again and (produce noise in the bandwidth＜=8KHz) usually, make the existence of digital low frequency carrier signal component of signal in the mixing restituted signal can not influence the play quality of simulating signal at voice.

The low frequency carrier signal modulation of digital signal is the key of simulating signal and digital signal mixed transport.Digital signal has in fact just become the modulated carrier signal of a simulation after low frequency modulations.Low frequency modulations can be OOK, AM, FM or other any pattern, but each pattern all must be carried out demodulation by the detuner with model identical after signal receives.No matter be modulation or demodulation, it is the simplest adopting the OOK pattern in practice.Above-mentioned analog/digital mixing signal is handled in same FM modulator/demodulator, thereby realizes the synchronous transmission of simulation and digital signal.Reception, demodulation and reduction part about carrier signal will be further described by relevant below paragraph.

Please refer to shown in Figure 9ly, the core of Fig. 9 is a FM receiver circuit or an integrated circuit, and this integrated circuit is responsible for the reception (abbreviation radio reception) of FM frequency modulation broadcasting and the reception of above-mentioned analog/digital hybrid FM carrier signal simultaneously.One functional select switch is arranged among the figure, can select radio reception or intercommunication function, this selector switch is actually the part of the functional select switch described in Fig. 3.When selecting the radio reception input, Fig. 9 is a traditional FM radio receiver, the FM signal is imported by antenna, and the clutter outside the FM broadcast band is filtered through the FM wave filter, enter the FM integrated circuit of radio receiver then, and the FM signal is amplified and demodulation by this integrated circuit, sound signal after the demodulation is earlier through a loudspeaker controller (being silencing apparatus), if this device is enabled (by aforesaid processor control), then this sound signal just is output to a volume adjustment device and carries out volume control, and then carry out power amplification, export by loudspeaker at last.Can also see in the drawings a FM tuned circuit is arranged, this tuned circuit is made up of LC oscillatory circuit or voltage controlled oscillator usually, and be connected to the local oscillator input circuit of integrated circuit of radio receiver, with the frequency-selecting that realizes that the FM signal receives, receiver circuit structure of this and routine is the same.

Another function of Fig. 9 is to realize the reception and the demodulation of the analog/digital hybrid FM modulated carrier signal described in above-mentioned Fig. 8, and this function is selected when selecting switch to place " intercommunication/phone ".In this pattern of intercommunication/phone, compound FM signal is imported (also can import from antenna) from line of electric force through the carrier wave coupled circuit, enter the FM integrated circuit of radio receiver through selector switch then, and the FM signal is amplified and demodulation by this integrated circuit, signal after the demodulation (reduction) is a mixed signal, has comprised audio analog signals described in Fig. 8 and low frequency digital carrier signal.The sound signal of reduction has two transmission channels, controlled by loudspeaker controller (when the intercommunication pattern be suitable for) and controller for telephone (in telephony mode time suitable).Audio signal output passage in the intercommunication pattern is consistent with the FM radio, and the sound signal in the telephony mode is transferred to telephone interface through behind the controller for telephone, and listens to received telephone audio signal in telephone set.Transmit simultaneously with sound signal and also had a low frequency digital carrier signal by what demodulation was come out, this signal also must be through the frequency-selecting of a low frequency carrier signal bandpass filter, and then deliver to the low frequency carrier signal detuner and carry out demodulation, just can restore the binary digit control signal, this digital controlled signal can be handled by aforesaid processor, and according to circumstances distinguish control loudspeaker control device or controller for telephone, thereby realize the intercommunication control of networking or the connection control of remote phone interface.

Figure 10 is modulation, the demodulation waveforms sequential chart of the digital signal of the embodiment of the invention one network digital alarm clock.The low frequency carrier signal modulator here is an OOK modulator, and the low frequency carrier signal detuner is an OOK detuner.Digital signal among the figure (original signal) shows as the binary format of high/low level (promptly open and close), and by digital signal low frequency carrier signal is carried out switch modulation, produces a series of on-off keying (OOK) signal.Carrier wave passes through when showing as high level in the drawings, and carrier wave ends during low level.Recovering signal is earlier through integrated circuit of radio receiver output, again by the demodulation of low frequency carrier signal detuner, obtains a binary switch recovering signal with the original signal homophase at last.In fact recovering signal and original signal just homophase still be anti-phase all no problem, as long as recovering signal and original signal have a clear and definite corresponding relation.

The transmission of digital signal is the basis of network control system, and for the control function that realizes that the present invention is above-mentioned, the effective order set of a cover is absolutely necessary.The functional requirement required according to system, the embodiment of the invention have defined the address code of nine word lengths, the parameter that the order code of six word lengths and eight bit word are long, and concrete data such as digital length, capacity and scope are shown in Table 1.
