The hazard detection system 205 that Fig. 2 shows just using in the illustrative closing space 200 according to some embodiments is said Bright property block diagram.Fig. 2 also illustrates optional hazard detection system 207 and router 222.Hazard detection system 205 can be similar with 207 Hazard detection system 105 and 107 in Fig. 1, the closing space 100 that closing space 200 can be similar in Fig. 1, and route The router 122 that device 222 can be similar in Fig. 1.Hazard detection system 205 may include multiple components, including system processor 210th, high power radio communication circuit 212 and antenna, low power wireless communication circuit 214 and antenna, nonvolatile memory 216th, loudspeaker 218, may include the sensing of one or more safety sensors 221 and one or more non-security sensor 222 Device 220, safe processor 230, siren 234, power supply 240, circuit for power conversion 242, high quality power circuit 243, power Gating circuit 244, microphone 250, self-examination module 260, self-examination module 260 include circuit 261, signal transacting 262, Scheduler 263 and user preference 264.Hazard detection system 205 be operable as use can make power consumption minimize circuit topology and Power budget approach provides faulty still safe safety detection feature and user interface feature.

Processor (bifurcated processor) circuit topology of bifurcated can be used to handle in hazard detection system 205 The feature of system 205.System processor 210 and safe processor 230 may be present on the same circuit board in system 205, but Perform different tasks.System processor 210 is the processor being more able to more greatly, can be consumed than safe processor 230 more Electric power.System processor 210 is operable as handling user interface feature.For example, the bootable high power channel radio of processor 210 Believe circuit 212 and wireless data traffic, access nonvolatile memory 216 and processing on low power wireless communication circuit 214 Device 230 communicates and makes to send audio from loudspeaker 218.And for example, processor 210 can monitor that one or more sensors 220 obtain The data taken, with determine the need for taking any action (for example, in response to the user that detects by the action of alarm silence, Turn off ear-piercing alarm).

Safe processor 230 is operable as the security related tasks of processing system 205.Safe processor 230 can poll biography One or more of sensor 220 and the activation police when the instruction of one or more of sensor 220 detects hazardous events Report device 234.Processor 230 can be operated independently of processor 210 and processor 210 is in that what state can all swash Siren 234 living.For example, if processor 210 is carrying out movable function (for example, performing WiFi renewals) or due to electric power Constrain and be turned off, then when detecting hazardous events, processor 230 can activate siren 234.In certain embodiments, exist The software run on processor 230 can be secured permanently, and can be after system 205 is dispatched from the factory always not via software or solid Part renewal is updated.In other embodiments, when system 205 be in it is live when, more new processor 230.

Compared with processor 210, processor 230 is the relatively low processor of power consumption.Therefore, replaced by using processor 230 Processor 210 is selected to monitor the subset of sensor 220, causes power saving.If processor 210 will monitor sensor 220 always, Power saving can not be realized.Except the subset of sensor 220 is monitored by using processor 230 come in addition to realizing power saving, also pass through by No matter processor bifurcated ensures whether processor 210 works, the security monitoring and core alerts feature of system 205 all will Operated.For example not limit, system processor 210 may include such as Freescale semiconductors K60 microcontrollers Relative high powers processor, and safe processor 230 may include the phase of such as Freescale semiconductors KL16 microcontrollers To the processor of low-power.The integrated operation of hazard detection system 205 needs system processor 210 and safe processor 230 Wise framework cooperates (judiciously architected cooperation), wherein, system processor 210 performs selected Select all the time routinely the higher level unrelated with hazard detection unit, advanced function (for example, the user interface of higher level And communication function；For sensing the various computation-intensive algorithms of user behavior pattern or environmental aspect pattern；For according to ring The algorithm of border gray scale control such as LED night-light brightness；For controlling the built-in speakers of such as household internal call function Sound level algorithm；The algorithm of voice command is for example issued the user with for controlling；For the data of daily record to be uploaded to The algorithm of central server；Algorithm for establishing network memberses etc.), and wherein, safe processor 230 performs all the time Routinely the more basic function more relevant with hazard detection unit is (for example, smog and CO monitoring, are activated when detecting alarm Scream/buzzing alarming).For example and not limit, when system processor 210 be in the active state of relative high powers and When execution is dispatched to one or more of its Premium Features, the consumption of system processor 210 can be about 18mW amount Level, and about 0.05mW magnitude can be only consumed when safe processor 230 is carrying out its basic function for monitoring.It is however, another Outside, for example not limit, when system processor 210 is in the inactive state of relative low-power, system processor 210 can only consume about 0.005mW magnitude, and advisably select its Premium Features to be performed and be determined the time, So that system processor is in about 0.05% that relative high powers active state only accounts for the time, and by the residue of the time Time spends in the inactive state of relative low-power.Being averaged for 0.05mW is only needed when being carrying out its basic function for monitoring While power draw, safe processor 230 should just perform its basic function for monitoring in the 100% of the time certainly.Root According to one or more embodiments, the wise form and function covering of system processor 210 and safe processor 230 is designed so that In the case that system processor 210 is deactivated (de-activate) or incapacitation, by safe processor 230 Hitless operation, hazard detection system 205 can to hazard conditions perform basis monitoring and/buzzing alarming of screaming.Therefore, though Right system processor 210 is configured and is programmed for offer to make that hazard detection unit 205 is interesting, it is expected, be renewable, easily With, intelligence, the sensing of networking and communication node to strengthen many different abilities of smart home environment, advantageously from as safety Processor 230 control core security operation covering or it is attached in the sense that says offer its function so that at system In the case that reason device 210 and its Premium Features have operational issue or difficulty, by the operation of safe processor 230, hazard detection The potential safety-related purpose and function of system 205 will also be with or without the situation of system processor 201 and its Premium Features Lower lasting progress.

High power radio communication circuit 212 can for example be communicated according to any one in 802.11 agreements Wi-Fi module.For example, the WiFi dash numbers BCM43362 for being available from Murata realizes circuit 212.According to system 205 operator scheme, circuit 212 can operate under low-power " dormancy " state or high power " activity " state.For example, work as system 205 when being in idle pulley, and circuit 212 can be at " dormancy " state.When system 205 is in such as Wi-Fi generation patterns, software During the non-idle mode of generation patterns or warning mode, circuit 212 can be at " activity " state.For example, when system 205 is in During Active Alerts pattern, high power circuit 212 can communicate with router 222 so that message may be sent to that remote server or Equipment.

Low power wireless communication circuit 214 can be can be according to the low-power wireless individual region of 802.15.4 protocol communications Net (6LoWPAN) module or ZigBee module.In certain embodiments, low power wireless communication circuit 214 can serve as equipment Fiber optic network in node.In another embodiment, circuit 214 can be obtained from Silicon Laboratories Part No. EM357SoC.In certain embodiments, circuit 214 can include Bluetooth Low Energy circuit.Depending on system 205 Operator scheme, circuit 214 can operate under relative low-power " dormancy " state or relative high powers " wake-up " state.Work as system 205 in idle pulley, WiFi generation patterns or during software upgrading pattern, and circuit 214 can be at " dormancy " state.In response to connecing The state of one received in wake-up packet (being transmitted by another equipment) or the state machine in response to being run in system 205 changes Become, circuit 214 can be converted to wake-up states from resting state.When system 205 is under warning mode, circuit 214 can be with Transmit optical fiber message so that the low power wireless communication circuit in system 207 can receive the number of 205 positive alarm of instruction system According to.Therefore, also can for this purpose even if high power radio communication circuit 212 can be used for monitoring alarm events, more power has Effect ground uses low-power circuit 214.When some hazard detection systems or other systems with low-power circuit 214 form interconnection Wireless fiber optic network when, also can further realize power saving.

Because in order that low-power circuit 214 continuously monitors the data of other low-power circuit transmission, circuit 214 can be with one Directly operated under its " dormancy " state, so can also realize power saving.This state power consumption, and although it, which can be consumed, compares Gao Gong Rate circuit 212 consumes more electric power when being operated under its resting state, but with must regularly activate high power circuit 214 Situation is compared, and the electric power saved can be quite a lot of.When high power circuit 212 is in its active state and low-power circuit 214 During in its waking state, high power circuit 212 can consume more electric power more obvious than low-power circuit 214.

In certain embodiments, the feature of low power wireless communication circuit 214 can be its relatively low power consumption and Qi Gen The ability for carrying out radio communication according to the first relatively low agreement of data rate is characterised by, and high power radio communication circuit 212 feature can be that its relatively high power consumption and its basis are characterised by that the relatively high second protocol of data rate is carried out wirelessly The ability of communication.

In certain embodiments, low power wireless communication circuit 214 can be mesh network compatible modules, it is not necessary to different Access point so as to the equipment communication in network.Mesh network compatibility may include to enable mesh network compatible modules to track attached Nearly other mesh network compatible modules cause the regulation that data can be transmitted by neighbouring module.Mesh network compatibility essence On be 802.15.4 agreements mark.Comparatively speaking, high power radio communication circuit 212 be not mesh network compatible modules and Access point is needed to be communicated with the equipment in network.Therefore, if the first equipment with circuit 212 is wanted and with electricity The miscellaneous equipment on road 212 enters row data communication, the first equipment must and access point communication, access point then transfer data to the Two equipment.Using circuit 212, substantially without equipment to equipment communication.

Nonvolatile memory 216 can all be deposited such as (e.g.) nand flash memory, hard disk drive, NOR, ROM or phase transformation Any suitable permanent memory of reservoir.In one embodiment, nonvolatile memory 216 can store and be available for loudspeaker 218 audio clips played.Audio clips may include installation instruction or the warning of one or more language.Loudspeaker 218 can be with It is any suitable loudspeaker for being operable as playing sound or audio file.Loudspeaker 218 may include amplifier (not shown).

Sensor 220 can be monitored by system processor 210 and safe processor 230, and may include safety sensor 221 With non-security sensor 222.One or more of sensor 220 can be specially by system processor 210 and safe processor 230 In one monitoring.As defined herein, monitor that sensor is energy of the finger processor from the sensors for data monitored Power.That is, a par-ticular processor can be responsible for obtaining sensing data, and it is possible to store it in sensor logs In, but data are once obtained, another processor can obtain the data by the data of log recording or the form of real time data. For example, in one embodiment, system processor 210 can monitor one in non-security sensor 222, but safe processor 230 can not monitor same non-security sensor.In another embodiment, safety sensor 230 can monitor safety sensor 221 In it is each, but the sensing data of acquisition can be supplied to system processor 210.

Safety sensor 221 may include to ensure that hazard detection system 205 can monitor the hazard conditions of its environment and work as To sensor necessary to user's alarm when detecting hazard conditions, and all other biography for detection hazard conditions necessarily Sensor is non-safety sensor 222.In certain embodiments, safety sensor 221 only include detection hazard conditions necessary to Those sensors.For example, if hazard conditions include smog and fire, safety sensor can only include Smoke Sensor, at least One temperature sensor and relative humidity sensor.Other sensors of such as non-security sensor can be included as system 205 Part, but need not can be used to detect smog or fire.And for example, if hazard conditions include carbon monoxide, safety sensor It can be carbon monoxide transducer, and may not be needed to perform this task with other sensors.

Therefore, be considered as function that necessary sensor can be based on hazard detection system 205 and feature and difference.At one In embodiment, hazard detection system 205 can be combination smog, fire and carbon monoxide alarm system.In such embodiments, Detecting system 205 may include following necessary safety sensor 221：Smoke-detectors, carbon monoxide (CO) sensor and one Or multiple temperature sensors.Smoke-detectors triggers smog bar usually using optical detection, ionization or air sampling technology Part.Light scattering and occlusion detection technology can use infrarede emitting diode (LED) and photodiode.When smog and/or its When his material (such as water vapour) enters smog chamber, scattered by the light that LED is sent so that photodiode detects the light. If there is no smog or other materials (such as vapor), photodiode to detect what is sent by LED in smog chamber Light.In certain embodiments, multiple LEDs can be incorporated in Smoke Sensor.Each LED can send light at different wavelengths Energy.Ionization technique can carry out ionized air using the radioactive substance of such as americium -241, and generation can between two plates of detector The electric current of measurement.When smoke particle enters the room, they and ions binding.Conduction electric current of the reaction between detector plates Decline instruction Smoke Detection that is middle to produce measurable decline, thus generating.It is traditional in some geographical position (such as Europe) The ionizing smoke detector of americium -241 is forbidden by regulator to a certain extent, and reason terminates in the service life of smoke-detectors Shi Bixu handles radioactive substance.Smoke-detectors can also using on-radiation ionization technique come detect smog and/or other The presence of particulate matter.On-radiation ionization detector can use the ultraviolet emission LED's such as with photocatalytic coating LED.When light (for example, UV light) passes through photochemical catalyst generation ion.When these ions by smog and/or other materials displacement or During neutralization, detector detects the curent change between two plates and records smog episode.

CO sensors can detect whether CO gas be present, and at home, CO gas is typically by naked light, small Type heating device, what water heater, the chimney blocked and automobile generated.The material used in electrochemical CO sensor generally has 5 to 7 The life-span in year.Therefore, after the time of 5 to 7 years expires, it should change CO sensors.Heat sensor can be thermistor, Thermistor is a kind of resistor of its resistance based on temperature change.Thermistor may include negative temperature coefficient (NTC) type temperature-sensitive Resistance or positive temperature coefficient (PTC) type thermistor.Relative humidity sensor can be used to distinguish by smog and steam or mist It is caused to block.In addition, in this embodiment, detecting system 205 may include following non-security sensor 222：Humidity passes Sensor, ambient light sensor, button sensor, passive infrared (PIR) sensor, one or more sonacs, acceleration Meter and camera.The purpose controlled for environmental surveillance and HVC, temperature and moisture sensors can provide relatively accurate temperature and relative Moisture readings.Ambient light sensor (ALS) can detect ambient light, and button sensor can be that for example whether detection user presses out The switch of pass.Pir sensor can be used for various motion detection features.Camera can also detect motion.Accelerometer can detect fortune Dynamic and vibration.Sonac can be used for the presence of detection object.Such sensor can generate high frequency sound wave and which is determined A little ripples are received back to by sensor.Sensor 220 can be installed in printed circuit board (PCB) (for example, processor 210 and 230 may be mounted to Same circuit board), flexible printed circuit board, system 205 shell or its combination.

In certain embodiments, the data obtained from one or more non-security sensors 222 can be used for from one or The same processor that multiple safety sensors 221 obtain data obtains.For example, safe processor 230 can be for the reason for the power saving And be operable as monitoring both safety sensor 221 and non-security sensor 222, as discussed above.Although safe processor The 230 any data that need not can be obtained from non-security sensor 222 endanger monitoring and alarm function to perform it, but available Non-security sensing data provides the function of harm system 205 of enhancing.In certain embodiments, non-security sensor 222 can With including microphone 250, sonac (not shown), accelerometer (not shown), external movement detector (not shown) and Camera (not shown).Its signal can be supplied to sound to check module 260 by each in these sensors.

Siren 234 can be any suitable alarm that user audibly near warning system 205 has hazard conditions Device.According to various embodiments discussed herein, moreover it is possible to activate siren 234 during selftest scene.For example, siren 234 can be piezoelectric buzzer, and it sends audible alarm with fixed frequency or in the range of certain frequency.Exemplary fixed frequency 3kHz or 520Hz can be included.In certain embodiments, siren 234 can be sent with the interval of interval with two different frequencies Audio warning.

System 205 can alternatively include siren 235, and it can audibly produce sound to warn (alert) to exist Another siren of hazard conditions.Siren 235 can also be activated during selftest.Siren 235 can also be pressure Electric buzzer.The sound of the different fixed frequency of siren 235 can be sent from siren 234 is sent fixed frequency.For example, Siren 234 can send sound with first frequency (for example, 3kHz), and siren 235 can with second frequency (for example, 520Hz) send sound.During alarm events, for example, siren 234 and 235 can send their own alarm in turn. For example, siren 234 can in the first interval sounding, during this period, can continuously or intermittently sounding, and at the first interval After end, siren 235 can second interval in sounding.During the second time interval, siren 235 can continuously or Intermittently sounding.If desired, additional siren can be included in system 205.In certain embodiments, system 205 can Only to include with the alarm of 520Hz frequency sounding.

Power supply 240 can supply the electric power for enabling system 205 to operate and may include any suitable energy source.Herein Combination that the embodiment of discussion may include to be powered by AC lines, be battery powered, powered by AC lines and carry reserve battery, by outside Supply DC electric power (for example, being powered by USB).Using AC lines power supply, AC lines power supply and with reserve battery, outside supply D/C power Embodiment can be subjected to different from the embodiment of only battery power saving constraints.The embodiment being battery powered is designed to manage The power consumption in its finite energy source so that period of the operation of hazard detection system 205 up to minimum.In certain embodiments, it is minimum Period can be (1) year, 3 (3) years or 7 (7) years.In other embodiments, the minimum period can be at least 7 (7) years, 8 (8) years, 9 (9) years or 10 (10) years.Do not constrained so by the embodiment of line powered, because they Energy source is actually unrestricted.It can be extended by line powered and the embodiment with reserve battery using electricity saving method standby The life-span of battery.

In the embodiment of only battery, power supply 240 includes one or more battery or battery pack.Battery can by it is different into Divide (for example, alkali metal or ferrous disulfide lithium) to form and different terminal users can be used to configure (for example, permanent, user Replaceable or non-user is replaceable).In one embodiment, can be by six Li-FeS₂Battery unit is arranged to three Two groups of one group.Such arrangement can be total available power that system 205 produces about 27000mWh.

Circuit for power conversion 242 is included circuit of the electric power from a level conversion into another level.Power can be used to turn Multiple examples of circuit 242 are changed to provide the different power levels needed for the component in system 205.Circuit for power conversion 242 One or more examples be operable as the signal that power supply 240 is supplied being converted into unlike signal.Circuit for power conversion 242 this The example of sample can exist in the form of buck converter or boost converter.For example, siren 234 can need than high electric power without The high operating voltage of line telecommunication circuit 212 (operating voltage higher than processor 210 can be needed) so that required all voltages are not It is same as the voltage of the supply of power supply 240.Therefore, as it is intelligible in this illustration, it is necessary to circuit for power conversion 242 at least three Individual different example.

High quality power circuit 243 is operable as from the specific reality of circuit for power conversion 242 (for example, buck converter) The Signal Regulation of example supply is into another signal.High quality power circuit 243 can exist in the form of low dropout regulator.It is low The signal that differential pressure regulator can provide the offer of specific power change-over circuit 242 has higher-quality signal.Therefore, can be Some components provide the power for having " higher " quality than other components.For example, such as certain of smoke-detectors and CO sensors A little safety sensors 221 need the voltage more more stable than the digital circuit in system processor 210 correctly to be operated.Such as It is described more fully below, power circuit can be customized to provide specific work(to each LED in Smoke Sensor Rate signal.

Power gating circuit 244 can be used for selectively component and power bus are coupled and decoupled.Component is total with power supply Line decoupling ensures that component will not cause any quiescent current loss, therefore can extend battery life, it will if more than component not So decoupled with power bus will caused by battery life.Power gating circuit 244 can be all brilliant such as (e.g.) MOSFET The switch of body pipe.Even if component decouples with power bus and does not cause any current loss, power gating circuit 244 itself Also a small amount of electricity can be consumed.However, the static power that the power consumption is less than component is lost.

Microphone 250 can be designed specifically to receive acoustic energy (such as sound) and convert thereof into the discrete of electric signal and Independent component.Microphone 250 can be located at the proximity of system 205 or be fully located at the inside of system 205.Example Such as, microphone 250 can be MEMS microphone.

As the alternative for including microphone 250 in system 205, when loudspeaker 218 is not used to transmit message, It may be used as microphone.Loudspeaker 218 is used as to the purposes of the existing component of microphone change, without causing to be used for such as wheat The fringe cost of the discrete microphone of gram wind 250.Therefore, selftest operate during, can be received by loudspeaker 218 and Handle the acoustic energy sent by siren 234 or 235.As another alternative, if siren 234 and 235 be present in be In system 205, then one of siren may be used as microphone, and another siren is then used as siren.Therefore, when first When siren sends alarm, the second alarm " can monitor " sound sent by the first alarm, or vice versa it is as the same.

Sonac 259 can also be used to verify the operation of siren 234 and/or siren 235.Although ultrasonic sensing Device 259 is tuned on about 40kHz, but it can pick up the higher hamonic wave of the fundamental frequency of siren 234, so as to verify its running.By It is very big in the loudness of siren 234, therefore strong audio frequency and electromagnetic signal can be generated in other sensors.In a reality Apply in mode, siren 234 is with 85dB@3m, the frequency sounding with 3kHz.Although sonac 259 can be tuned to Sent far above normal human auditory 40kHz and detection signal, but its can detect sent by siren 234 it is loud 11st time and the 12nd subharmonic (33kHz and 36kHz) of sound.These harmonic waves are in the detection range of sonac 259. Siren 234 has complicated (full harmonic wave) waveform, therefore the 11st and the 12nd subharmonic is also quite loud.Sonac 259 circuits that need not be added clearly show that 234 positive sounding of siren.It is to be understood that the institute collected from siren 234 Have that information is invalid for any purposes for being used primarily for sensor 259, but only during the period, the sounding of siren 234.This Outside, in the present invention, siren 234 provides the electromagnetic interference of the operation to sensor 259.

Accelerometer (not shown) can be the MEMS device that can detect motion.Accelerometer 254 can be used for it is a variety of not Same purpose, including the automation selftest of siren 234 and/or siren 235.For example, accelerometer 254 can by with To determine that system is installed to the orientation of fixation surface (such as wall or ceiling).Whether this can be used to determine system 205 It is moved to theft detection.In addition, accelerometer 254 can be used to detection vibration as caused by Active Alerts.That is, When siren 234 is sending its alarm signal, in response to this, the vibration sensed in systems can the detection of degree of being accelerated meter Arrive.If vibration signal fully matches with desired outline data or can be according to desired specification more than threshold value, system 205 Determine that siren 234 operates.

The (not shown) of external movement detector 256 can be the equipment of motion that can be outside detecting system 205.For example, Detector 256 can be passive infrared motion detectors.Camera (not shown) can detect the occupant in structure Motion or existing another equipment.Exercise data can be used together with automatic selftest system to determine to perform selftest Best Times.Because siren 234 is very loud, it may be desirable to selftest is performed when occupant is absent from the scene, to avoid doing Disturb occupant.

System 205 can include various voice authentication sources.Voice authentication source can be detected by siren and/or buzzer The equipment or component of the audio signal sent.Voice authentication source can include microphone, siren, loudspeaker, sonac, Accelerometer or capacitance type sensor.These voice authentication sources their signal can be fed to sound check module 260 with For analysis.In certain embodiments, voice authentication source may be located remotely from system 205 and place.For example, Mike's wind energy in phone by with To detect the audio signal sent by system 205.

Selftest module 260 can control selftest to verify the operation of the one or more assemblies of system 200.Example Such as, selftest can be with the operation of verificating sensor 220, power supply 240, siren 234 and microphone 250.One of test Can be sound test, to verify that siren 234 and 235 and loudspeaker 218 are run with the specified loudness of minimum and frequency.Self Test module 260 can include being used for the circuit 261 and signal transacting 262 for handling the signal received from voice authentication source.One In a little embodiments, circuit 261 can include digital filter, and signal transacting 262 can include explanation and be provided by circuit 261 Signal code.In certain embodiments, circuit 261 and signal transacting 262 can embody frequency spectrum analyser, and it analyzes audio Signal is to determine whether siren and/or loudspeaker send signal with desired frequency.Selftest module 260 can be to receiving Audio signal perform a large amount of analyses.These are analyzed the amplitude for the audio signal that can determine to be sent by siren, frequency and held The continuous time.These analyses can classify over time, to determine whether any penalty.

It will be appreciated that although hazard detection system 205 is described as having two single processors, you can provide as above With some advantages as described below (including on power consumption and in advance feature regulation problem (advanced feature Provision issue) in the case of carry out core security monitoring and alarm tolerance the advantages of) system processor 210 With safe processor 230, but by a processor or the various realities being not discussed herein by more than two computing device Outside the scope for applying this teaching of one or more of example.

Fig. 3 illustrate that worked together according to the various assemblies of the hazard detection system 300 of various embodiments it is more to provide The illustrative block diagram of standard alarm and precaution alarm function.As shown, system 300 may include sensing data 302, Jing Yin inspection Survey event 304, changing condition 306, threshold value adjustment parameter 307, multi-standard state machine 310, clock 312, other states 320, police Report state 330, precaution alarm state 340, siren 350, display 352, loudspeaker 354 and radio-circuit 380.Also illustrate some Communication link 370, each in communication link 370 have unidirectional or bi-directional data and/or signal communication capability.Multi-standard shape State machine 310 can be controlled based on sensing data 302, Jing Yin detecting event 304, changing condition 306, clock 312 and other standards Alarm state 330, precaution alarm state 340 and all other state machine state 320 processed, and alarm state 330 and precaution alarm shape State 340 can control the output of siren 350, display 352 and loudspeaker 354.Alarm state 330 may include a variety of alarm states (for example, one alarm state of every kind of harm, such as, smog alert state 331, CO alarm states 332 and heat alarm state 333) And precaution alarm state 340 may include a variety of precaution alarm states (for example, every kind of endanger one or more alarm states, such as, cigarette Mist precaution alarm state 341 and CO precaution alarms state 342).Other states may include that for example idle condition, monitored state, alarm are quiet Mute state, hold mode and alarm monitor state after mute state, alarm before sound-like state, alarm.

The determination that alarm state 330 may be in response to the progress of multi-standard state machine 310 controls siren 350 and display 352 activation and deactivation.Siren 350 can provide the audible prompting on dangerous situation (for example, buzzer bleep Form).Display 352 can provide the visual cues (for example, such as flash lamp or color change) of dangerous situation.If any Need, alarm state 330 can combine audible and/or visual cues and play message by loudspeaker 354 to control.For example, alarm Repeatable following sequence is applied in combination in device 350 and loudspeaker 354：" serge serge, serge serge, serge serge-detect in bedroom have smog- Serge serge serge serge serge serge ", wherein, send " serge serge " from siren 350 and send that " detecting has cigarette in bedroom from loudspeaker 354 Mist ".And for example, the use of siren 350 and loudspeaker 354 repeats following sequence：" serge serge, serge serge, serge serge-wave alarm Jing Yin-serge serge serge serge serge serge ", wherein, instructed using loudspeaker 354 to provide alarm silence.Alarm state 330 is (for example, smog Alarm state 331, CO alarm states 332 and heat alarm state 333) any of can independently control siren 350 and/or Display 352 and/or loudspeaker 354.In certain embodiments, alarm state 330 can make siren 350 or display 352 or Loudspeaker 354 sends different promptings, and based on this, particular alert state is movable.For example, if smog alert state is living Dynamic, then siren 350 can send the sound with fisrt feature, but if CO alarm states are movable, siren 350 can Send the sound with second feature.In other embodiments, alarm state 330 can make siren 350 and display 352 and raise Sound device 354 sends same prompt, which kind of particular alert state to be movable but regardless of.

The determination that precaution alarm state 340 may be in response to the progress of multi-standard state machine 310 comes controlling loudspeaker 354 and display 352 activation and deactivation.Precaution alarm can be used as the warning that unsafe condition may approach.Danger is played using loudspeaker 354 The voice warning that situation may approach.The each type of precaution alarm event detected can be directed to play not by loudspeaker 354 Same precaution alarm message.For example, if smog precaution alarm state is movable, it is related smog can be played by loudspeaker 354 Message.If CO precaution alarm states are movable, CO related news are can play.In addition, can be directed to it is each endanger (for example, Smog and CO) each precaution alarm in associated a variety of precaution alarms, play different message.For example, smog injury can have Two associated precaution alarms, i.e. a precaution alarm associated with the first smog precaution alarm state are (for example, imply alarm state May moderately approach) and another related to the second smog precaution alarm state precaution alarm (for example, implying just there is being alarm state height Degree approaches).How precaution alarm message may also include by the Jing Yin phonetic order of precaution alarm message.It can also utilize in a similar manner Display 352 provides the visual cues for the alarm state approached.In certain embodiments, precaution alarm message may specify precaution alarm The position of situation.For example, if harm system 300 knows its position in bedroom, the position can be incorporated to precaution alarm by it In message " detecting has smog in bedroom ".

Hazard detection system 300 can implement alarm and precaution alarm priority ranking according to which situation be present.For example, such as There is elevated smog and CO situation in fruit, smog alert state and/or precaution alarm smoke condition can be prior to CO alarm states simultaneously With/CO precaution alarm states.If user makes smog alert or smog precaution alarm is noiseless and CO alarm states or CO precaution alarm states Still movable, then system 300 can provide CO alarms or precaution alarm also by noiseless instruction (for example, verbal announcement).If Smoke condition terminates and CO alarms or precaution alarm are still movable, then CO alarms or precaution alarm can be presented to user.

When it is determined that during in the presence of situation that is relatively rarely dangerous or being safe from danger, multi-standard state machine 310 can be converted to sky Not busy state.Idle condition can force to carry out the relatively low activity level of hazard detection system., can be with for example, in an idle state The data sample rates of the relatively low one or more sensors of interval setting.When it is determined that sensor data values have risen to guarantee When having the level of more close scrutiny but being not reaching to the level for being converted to precaution alarm or alarm state, multi-standard state machine 310 can It is converted to monitored state.Monitored state can infer the relatively high activity level of hazard detection system.For example, in monitored state, The data sample rates of one or more sensors can be much larger than idle condition.In addition, alarm state 330, early warning can be directed to Report state 340 or both, with the data sample rates of the relatively fast one or more sensors of interval setting.

Alarm silence and precaution alarm mute state can refer in predetermined time amount, alarm or precaution alarm by user instruction Deactivation.For example, in one embodiment, user can press button (not shown) to make alarm or precaution alarm noiseless.Another In one embodiment, user can perform Jing Yin posture in the presence of hazard detection system.Jing Yin posture can be user The action of initiation, wherein he or she performs posture (for example, waving to act) near system 300 turns off ear-piercing alarm with intention It is or noiseless.One or more sonacs, pir sensor or its combination can be used to detect this posture.In another kind side In method, radio-circuit 370 can receive the instruction of mute alarm.For example, user can be using his or her phone come via nothing Wire protocol (for example, Bluetooth Low Energy), to system 300 transmit mute command, thus radio-circuit 380 can forward the order with Trigger Jing Yin detecting event 304.

Alarm state can refer to multi-standard state machine 310 in one or precaution alarm being in alarm state 330 afterwards The state that can be converted to after one in state 340.After one in alarm state, hazard detection system 300 can provide use " all clear " message of alarm or precaution alarm situation no longer be present in instruction.For example, for CO, this can especially have With because people can not detect CO.Alarm state can be to maintain state after another kind, and hold mode can be used as system knock-on shape State.The state can prevent hazard detection system 300 from just transforming back into precaution alarm shape immediately after the transformation of alarm state 330 just State 340.

Multi-standard state machine 310 may include some different state machines：Sensor states machine and system mode machine.Each shape State machine can be associated with all specific harm such as (e.g.) smog injury, carbon monoxide harm or heat harm, and multi-standard shape State machine 310 is using the data obtained when management of hazard detects by one or more sensors.In certain embodiments, can pin Sensor states machine is realized to every kind of harm.In other embodiments, the subset that can be directed to every kind of harm or harm realizes system State machine.Sensor states machine can be responsible for controlling the hazard detection systemic-function of comparative basis and system mode machine can be born Blame for controlling relatively advanced hazard detection systemic-function.In the detection of management of hazard, each sensor states machine and every Individual system mode machine can be based on sensing data 302, mute event 304 and changing condition 306 and turn between its any state Become.Mute event can be Client-initiated by the Jing Yin order of for example loud alarm or precaution alarm phonetic order.

Changing condition 306 may include various different conditions, and how these condition definable state machines are from a kind of shape State is transformed into another kind.Each state machine can have the set of the changing condition of its own.These conditions can limit available for Any one or more threshold values being compared in inputting below：Sensor data values, time clock and user mutual event (example Such as, mute event).Can be by relatively simple condition (for example, single standard conditions) or relative complex condition (for example, multi-standard Condition) carry out state of a control change transformation.Single standard conditions can be by an input compared with a threshold value.For example, single bar Part can be the comparison between sensor data values and threshold value.If sensor data values equal or exceed threshold value, can perform State change changes.Comparatively speaking, multi-standard condition can be compared one or more input with one or more threshold values Compared with.For example, multi-standard condition can be comparison and second sensor value and second between first sensor value and first threshold Comparison between threshold value.In some embodiments, it is desirable to meet that the two compare to realize that state change changes.In other realities Apply in example, will only need one in meeting these relatively to realize that state change changes.And for example, multi-standard condition can be The comparison between comparison and sensor values and threshold value between time clock and time threshold.

In certain embodiments, the threshold value of adjustable special transition condition.Such threshold value is referred to herein as adjustable threshold Value (for example, being shown as the part of changing condition 306).Threshold value adjustment parameter 307 be may be in response to change adjustable threshold, example Such as, according to embodiment, threshold value adjustment parameter 307 is provided by alert threshold setup module.Adjustable threshold may be selected from least two One in the individual optional threshold value of difference, and any suitable selection standard can be used to select to be suitable as the threshold of adjustable threshold Value.In one embodiment, selection standard may include some single standard conditions or multi-standard condition.In another embodiment, If by adjustable threshold compared with the sensor values of first sensor, selection standard may include except first sensor it The analysis of outer at least one sensor.In another embodiment, adjustable threshold can be made in smog alert changing condition Threshold value, and adjustable threshold may be selected from one in three different threshold values.

In certain embodiments, the threshold value of special transition condition can be the condition threshold (not shown) through study.The study of Confucian classics The condition threshold of habit can be the result for the difference function that constant can be subtracted from initial threshold.If desired, it can be based on any suitable The standard of quantity is closed to change the constant, the standard include such as inspiration, account on the spot data, software upgrading, user preference, Equipment setting etc..The machine for changing changing condition for one or more states (for example, precaution alarm state) can be provided by changing constant System.The constant is provided to changing condition 306, so that the condition threshold through study to be adjusted.In one embodiment, may be used Installation and setting based on hazard detection system 300 select the constant.For example, house owner may indicate that hazard detection system 300 have been installed within the particular room of closing space.Suitable constant may be selected in which room, system 300 according to it. For example, if room is bedroom, first constant may be selected, and if room is kitchen, then second constant may be selected.Compared to Second constant, first constant can be the values for making hazard detection system 300 more sensitive to potential hazard, because bedroom is in general Distance, which exports farther position and/or the general script that cannot be easily caused, can cause the factor of false alarm.Comparatively speaking, kitchen is than sleeping Room is for example typically closer to exporting and can generate the condition (for example, steam or smog from culinary art) of false alarm of causing. When selecting suitable constant, it is also contemplated that other installation factors.For example, house owner may specify the room and bathroom phase It is adjacent.Because the humidity from bathroom can cause false alarm, therefore endanger system 300 and may be selected to consider the constant of this point.And for example, House owner may specify that the room includes fireplace.Similarly, system 300 is endangered to may be selected to consider the constant of the factor.

In another embodiment, hazard detection system 300, which can be applied to inspire, comes from regulating constant.For example, condition can be held Keep triggering precaution alarm long, but the condition does not rise to Alert Level.Triggered in response to such persistently precaution alarm, hazard detection System 300 can change constant so that precaution alarm is not so triggered easily.In other embodiments, it may be in response to software upgrading To change the constant.For example, remote server can analyze the data that are obtained from some other hazard detection systems and correspondingly Regulating constant, and new constant is pushed to hazard detection system 300 via software upgrading.In addition, remote server can also incite somebody to action Hazard detection system 300 is pushed under constant based on user's setting or user preference.For example, house owner be able to can pass through Directly interacted with hazard detection system 300 to define the setting of limited quantity.However, house owner can by with example As remote server trustship based on web program interaction defines an infinite number of setting.Based on the setting, remote service Device can push away one or more suitable constants down.

Sensor states machine can control one or more of alarm state 330 and other states 320.Specifically, smog Sensor states machine 314 can control smog alert state 331, and CO sensor states machine 316 can control CO alarm states 332, with And heat sensor state machine 318 can control heat alarm state 333.For example, Smoke Sensor state machine 314 be operable as in response to The smog episode that detects and send siren 350.And for example, CO sensor states machine 316 may be in response to the CO events detected And send siren 350.For another example, heat sensor state machine 318 may be in response to the incident heat detected and send siren 350. In certain embodiments, sensor states machine can implement the special control to one or more alarm states 330.

The security feature of system 500 is robust, and electric power is effective, and failure-free operation.In order to ensure robust and electricity Security feature is efficiently used in power, and system 500 can be carried out as follows operation.Circuit for power conversion 540 and 542 is in its most short operation longevity Hit connects (at least expection in system 500 and commonly used period) all the time.Scenario described below may be present：Such as, when system 500 When undergoing the replacement of full power cycle, circuit for power conversion 540 and 542 is not always on.Thus, it is fed to power bus 541 It can be used for downstream components always with the electric power on 543.These components may include system processor 510, safe processor 530, non- Volatile memory 516, low dropout regulator 548, low dropout regulator 574 and safety sensor (such as ALS sensors 522, Temperature and moisture sensors 523, smoke-detectors 524, CO sensors 525, thermistor 526 and pir sensor 527).Safety Processor 530 and safe processor access electric power via always on circuit for power conversion 540 and 542, so that it is guaranteed that system 500 consistently monitor hazardous events.

Compareed because being formed with system processor 510, safe processor 530 is exclusively used in monitoring safety for hazard conditions Sensor, so power saving can be realized.Extra power saving can be realized by the various assemblies of power gating.Specifically, safe place Reason device 530 can independently control each in power gating circuit 553 and 555.Therefore, processor 530 can be by controlling respectively Power gating circuit 553 and 555 processed, display module 528 and power bus 508, and ALS sensors 522, temperature humidity are passed Each in sensor 523 and accelerometer 572 is selectively coupled and decoupled with power bus 541.

Safe processor 530 further can manage power consumption by selectively enabling circuit for power conversion 546.Processor 530 can be by applying appropriate signal to enable or disable circuit 546 to control node 558.When change-over circuit 546 enables, it The signal of the 5th voltage level can be provided to power bus 547.Processor 530 can when detecting hazardous events enable circuit 546, once and enable circuit 546, siren 534 be just operable as sending its alarm.When do not detect hazardous events or Person does not need siren 534, and processor 530 can disable circuit 546 when being activated.Disabling circuit 546 reduces circuit 546 and operated The electric power that the power loss and siren 534 of period can be consumed otherwise.

Processor 510 can also implement electrical management.Processor 510 can independently control power gating circuit 561,562, 563rd, 565 and other circuit (not shown) in each.Therefore, processor 510 can be by controlling appropriate power gating electricity Road, by 6LoWPAN modules 514 and power bus 541, FEM 515 and power bus 543, WiFi module 512 and power bus 541st, nonvolatile memory 516 is selectively coupled and decoupled with power bus 541.These power gating compatible components can be complete Disconnected entirely with power bus and remain able to correctly play a role when reconnecting to their corresponding power bus.

System processor 510 and safe processor 530 can be operated according to some different power modes.For example, from non- In the sense that often simple, both processors 510 and 530 can operate under activity pattern and park mode.And for example, processor 510 Can have various activities pattern and a variety of park modes with one or more of 530, each pattern has different power consumption water It is flat.Each processor carries out operating the pattern operation that AD HOC used may depend on system 500.If for example, system 500 Idle pulley in operation, then system processor 510 can be relative deep sleep mode, and safe processor 530 can be located In the activity pattern of relative low-power.

Fig. 6 shows the illustrative diagram of the fiber optic network 600 according to embodiment.Fiber optic network 600 can include making With one or more different communication protocols come two or more equipment wirelessly.Communication protocol can include Such as IPv6 (IPv6).The equipment of network 600 can be located at whole closing space, in such as house or building. Positioning and interfering component present in it, some equipment depending on the equipment in structure may not be directly in communication with each other.Example Such as, as shown in fig. 6, equipment 610 directly can communicate (as shown by the solid line) with equipment 620 and 630, but can not direct and equipment 640 communications (shown in dotted line).Equipment 610 can communicate with equipment 640 indirectly via equipment 620 or 630 because equipment 620 and 630 can directly communicate (as shown by the solid line) with equipment 640.Two or more in equipment 610,620,630 and 640 can To be hazard detection system.

Fiber optic network 600 can represent multihop network, wherein, at least one equipment, which is used as retransmitting, stands, for will be from initial The message that person's equipment receives is relayed to destination equipment, because initiator and destination equipment can not be directly in communication with each other.Institute Multiple factors can be depended on by needing hop count, ability that size, the equipment of network communicate with one another etc..Fiber optic network 600 can be with Represent Two-Hop：First jump is present between equipment 610 and equipment 620 or equipment 630, and the second jump is present in equipment Between 620 or 630 and equipment 640.For example, if equipment 610 and 640 directly could communicate with other equipment, fiber optic network 600 will be single-hop networks.

Equipment 610,620,630 and 640 has been marked as initiator, long-range 1 (R1), long-range 2 (R2) and long-range 3 (R3). These titles can be cited to indicate which equipment serves as the initiator of communication and which equipment is served as initially herein The recipient of the message of person.As its name suggests, initiator is in response to monitoring in it condition starts the equipment of fiber optic communication, And the message broadcasted by initiator is distributed to remote equipment so that remote equipment can respond the message broadcasted by initiator To take appropriate action.Remote equipment can transmit message in response to the message of initiator, but initiator decides whether to abide by Keep the message of remote equipment.For example, initiator by notify remote equipment its carrying out sound test and initiate fiber optic communication. In response to receiving sound test post, remote equipment takes appropriate action (for example, delay starts the test of its sound).When true Determine initiator completed its sound test when, remote equipment can broadcast the sound test post of their own.Other remotely set It is standby to postpone when receiving sound test post and start their sound inspection, untill they determine to be adapted to start.

Equipment can be broadcast the message in non-NULL channel assessment (NCCA) pattern and clear channel assessment (CCA) (CCA) pattern or Packet.Under NCCA patterns, the state regardless of communication channel, equipment can repeated broadcast its packet.Therefore, this Under pattern, there is a possibility that packet may make fiber optic network saturation, because more than one equipment can be in NCCA patterns Broadcast simultaneously.In CCA patterns, before broadcast packe is attempted, whether equipment can determine any other equipment first Communicated on channel.In fact, the equipment operated in CCA patterns contends with one other to determine that who is broadcasted.

After all devices in a network are waken up, message can be transmitted on fiber optic network.Setting in fiber optic network It is standby to need to be waken up, because their most of service life is spent under the park mode of low-power consumption.As long as waking up, it Can mutually transmit information.More specifically, once equipment is waken up, optical fiber can be considered as " synchronous ", in other words, It is " wake-up ".For example, system processor, Wifi radio and other circuits can be converted to height from low-power or closed mode Power or opening.Correspondingly, can be using system processor come the formation in whole optical fiber and the number of circulation relative abundance According to and/or order.These data and/or order can include for example identifying the information of the position of initiator, increase sample rate Instruction etc..By activating telecommunication circuit (for example, Wifi telecommunication circuits) in addition to low power communication circuit, these data and/ Or order (for example, via access point) can also transmit outside optical fiber.Therefore, equipment in fiber optic network wakes up and same After step, optical fiber message can be broadcasted on network, for traveling to any number of remote equipments from initiator's equipment.Can according to The broadcasting scheme operated on multihop network transmits optical fiber message.The broadcasting scheme can be the net that number of devices is unknown or changes Effective transmission example of network.In one embodiment, the program can be based on to Web broadcast single message and in whole net The message is flooded in network to define broadcasting primitive.The program can be by the forwarding of message and propagation and the processing of message payload Separated with understanding.

Fig. 7 shows that according to embodiment the sound that the audible component in hazard detection system is included in for self-management is surveyed The exemplary process diagram of the step of examination.The self-management of sound inspection can be performed by hazard detection system, without requiring user Interact to start the test in the structure comprising system or any occupant be present.Since step 710, it may be determined that for holding The time frame of row sound inspection.Fig. 2 sound test module 260 can aid in determination time frame.Specifically, module 260 can To determine time frame using scheduler 263 and user preference 264.Time frame can be characterized as testing time for defining roughly and The testing time of explication.Rough time can in a few days calendar day, and explication testing time can refer to it is intraday Specific Time of Day or time range.Thus, for example, can for example with monthly, quarterly, every half a year or during annual particular day Between based on perform sound inspection.Time frame can be determined based on any number of appropriate factors.For example, time frame can be in day On the basis of going through, based on intraday user-defined time frame or time range.As another example, time frame can contemplate table Show the occupancy data that whether there is any occupant in the structure (for example, when owner is in, it is undesirable to run sound inspection Look into).Time frame may also take into the situation of hazard detection system.For example, if hazard detection system detectio is endangered to potential Evil, sound test can be delayed to another time.As another example, if there is the accuracy that can influence sound test Environmental condition (for example, endangering system detectio to big ambient noise), then sound test can be delayed by or cancel, until next day Untill going through testDate.

Time frame can be determined by one or several different equipment.For example, in one embodiment, hazard detection system System can be the sole determinant of time frame.As another example, directly can be communicated with hazard detection system or with and harm The mobile device of the communication for service of detecting system communication can make user define the parameter of time frame.Therefore, when user uses shifting During dynamic device definition time frame, these parameters can be sent to hazard detection system or service so that enter in reasonable time Row sound is tested.If desired, hazard detection system can be adjusted to user-defined parameter, so as to cause modification time Frame.As another example, service can determine time frame.The service can access the account associated with hazard detection system, And knowledge with user preference, other measurements for taking data and making its definition testing time.

Be present in multiple hazard detection systems in the embodiment in public structure, can be different to each Systematic selection when Between frame so that sound test in be not present it is overlapping.Prevent overlapping sound is tested from can strengthen each self-management sound test The effect of.For each hazard detection system different time frame can only on the testing time of explication it is different, And the testing time defined roughly can be identical.Therefore, can have different in test day, each hazard detection system Sound tests the time started, to avoid overlap test.

In step 720, hazard detection system can be in the sound at least one audible source of identified time frame self-management Sound is tested.During the sound test of self-management, each audible source, which can be commanded, sends audio signal, and is sending this While audio signal, the equipment monitor of sent audio signal is detected.Audible source can be such as loudspeaker or buzzing Device.In certain embodiments, system can include loudspeaker and buzzer simultaneously.The audio that detection is sent by each audible source is believed Number equipment can include such as microphone.Other audio signal detectors can include such as energy detector, correlation reception Device, loudspeaker, buzzer, sonac, accelerometer and other voice authentication equipment.The identical of audible source is served as to raise one's voice Device can be used to the audio signal that monitoring is sent by buzzer.Similarly, serve as the identical buzzer in audible source can monitor by The audio signal that loudspeaker is sent.As an alternative, system can include two buzzers so that can be sent out with two different frequencies Go out alarm.In such a system, the audio signal sent by another buzzer can be monitored using a buzzer, or instead It is as the same.Sonac can be configured as monitoring the higher hamonic wave in any one or more audible sources.Non-audio detector energy It is used to the audio signal that detection is sent by audible source.For example, non-audio detector can include capacitance type sensor and acceleration Degree meter.Capacitance type sensor can be directly coupled to buzzer or adjacent with buzzer.When buzzer sounding, can vibrate, So as to cause the measurable change by the electric capacity of test using capacitance sensor.Similarly, when buzzer sounding, accelerometer energy Enough measure the vibration sensed in systems.

In step 730, system is able to verify that whether at least one audible source is tested by the sound of self-management.System can be with Checking is performed using a variety of technologies.Some in these technologies can be related to included in processor (for example, at system Manage device 210) in the limited software area of coverage in operation signal transacting.System can be performed to each audible source and individually tested Card.For example, loudspeaker can be assessed according to loudspeaker sound test, and can be tested according to buzzer sound to assess honeybee Ring device.The other details of these tests are discussed below.

In step 740, the result that sound is tested can be reported.This report can be shown in a number of different ways.One In kind method, based on result, hazard detection system can make its vehicle lighting system send particular color or display particular color Pattern.In another approach, hazard detection system can be based on test result, pass through loudspeaker playback messages.At another In method, result can be sent to service by system, and these results then are distributed into mobile device, and it can show result. As an alternative, result can be transferred directly to mobile device by system.

It will be appreciated that what the step of shown in Fig. 7 was merely exemplary, and additional step can be increased and can be with Omit step.The other details for realizing one or more above-mentioned steps is discussed in detail below.

Fig. 8 is shown in hazard detection system, can be used with exemplary process diagram the step of selftest buzzer. The system can include buzzer and motion sensor etc..Since step 810, it is based at least partially on and is obtained by motion sensor The data taken come determine perform buzzer sound inspection non-intruding time frame.Because most people thinks that buzzer is loud And undesirable sound, it is non-to generally working or living in the occupant in the structure comprising hazard detection system it is expected to work as During intrusion, sound inspection is performed.As herein defined, non-intrusion type time frame be implement buzzer (and/or loudspeaker and Other audible sources) self-management sound inspection, to generally living in the occupant in the structure comprising hazard detection system There are minimum or the time influenceed without the sense of hearing.In other words, the non-intruding time is reasonably to know occupant is not present in structure Time.

By it is any number of it is different in a manner of determine the non-intruding time.A kind of method is directed to use with motion sensor to be closed The data of occupant when are detected in structure.Occupied information can be analyzed to determine occupancy pattern.These patterns and its His factor, such as Time of Day, user preference and other factors can provide the statistical guarantee that any occupant whether there is.Example Such as, motion sensor data can indicate little or no movement between at 11 points in the morning on weekdays and at 4 points in afternoon, Yi Ji Few movements between 1 point to 5 points of night.Using these information and time factor, the non-intruding time can be selected as In at 11 points in any workaday morning to afternoon 4 points of time frame.

The non-intruding time can be automatically determined, without user intervention.In one embodiment, hazard detection system can be only Any other system (for example, service or mobile device) is stood on to make a decision.In another embodiment, hazard detection system can be tied Close and determine that the service of non-intruding time operates.In another embodiment, hazard detection system and/or service can be determined and tied up Surely the position for the mobile device that the account of hazard detection system is associated is arrived, to determine the non-intruding time.If for example, association Mobile device position be it is known, then the non-intruding time can with based on when know mobile device in the structure when Between.

In step 820, can it is determined that non-intruding time frame at self-management buzzer sound inspection.For example, sound Sound inspection can include interim activation buzzer, during activation buzzer temporarily, monitor the audio signal of microphone, and really Whether audio signal meets sound check criteria.The more detailed description of buzzer sound inspection can be found below. Step 830, the result of self-management sound inspection can be reported.The report that this report Fig. 7 above in conjunction is discussed is identical.

Some structures can have the more than one hazard detection system being included in.For these structures, it is expected Prevent overlapping sound from testing so that one test of management is not influenceed by other one or more tests are managed simultaneously.In order to Avoid overlap test, at the beginning of each sound test that can stagger between.Stagger to realize in a number of different ways, Hereinafter, Fig. 9-11 will be combined and discusses some of which.

Fig. 9 is shown according to embodiment, for preventing from performing multiple harm of self-management sound test in public structure The flow chart of the process 900 of sound interference in detecting system.Process 900 can be by regularly communicating with hazard detection system Service realize.Service can regularly be communicated with hazard detection system, and except other things, safeguard user account, Sending out notice is provided to user's mobile device, and represents the central service that hazard detection system provides the disposal ability of enhancing. Since step 910, service can be to each determination sound review time table in multiple hazard detection systems.For example, should It is known that how many hazard detection systems be present in the structure in service.Based on the knowledge, it can distribute what is staggered to each system Sound checks the time started.For example, at least each system that can stagger between at the beginning of staggering completes the time needed for its test Amount.Therefore, the first system can be in time t₀Start, and each follow-up system can be in time t_n*constantStart, wherein, n It is the quantity of follow-up system, and constant is fixed duration.

In step 920, sound inspection can be dispatched to each being sent in multiple hazard detection systems, wherein, it is more Each in individual hazard detection system dispatches execution sound inspection according to sound inspection.In step 930, service can be from multiple Each in hazard detection system receives the report that expression sound tests whether to pass through.

Figure 10 shows the multiple danger for being used to prevent to perform the test of self-management sound in public structure according to embodiment The flow chart of the process 1000 of sound interference between evil detecting system.Process 1000 can by the first hazard detection system come Implement.Since step 1010, instruction can be received to start the sound inspection of at least buzzer.The source of instruction can change. For example, in one embodiment, the source of instruction can be derived from mobile device (for example, user initiates sound by interacting with the application Sound is tested).Then, mobile device can be with the communication for service by the dictation trunk to the first hazard detection system.In another reality Apply in example, the source of instruction can come from service.In another embodiment, the source of instruction can be derived from the first hazard detection system.

Step 1020 and 1030 can be performed respectively before sound test is started.In step 1020, the first system can be with Establish and connect with the remainder of multiple hazard detection systems.It is, for example, possible to use low-power fiber optic network is (for example, Fig. 6 light Fibre web network 600) connected to establish.In step 1030, the first system can be to each determination in multiple hazard detection systems Sound inspection beginning order, wherein, sound inspection beginning order specifies when each hazard detection system performs its sound inspection, So that any hazard detection system of hazard detection system will not be simultaneously emitted by audio signal.The first system can be to each system System, including their own are randomly assigned the sound test time started, or can be oneself the first testing time piece of distribution, and Give at random or purposefully other systems allocation for test timeslice.In step 1040, the first system can be according to the sound of determination Test beginning order and start sound test.

Figure 11 shows the multiple danger for being used to prevent to perform the test of self-management sound in public structure according to embodiment The flow chart of the process 1100 of sound interference between evil detecting system.Process 1100 can by the first hazard detection system come Realize.Process 1100 shows that each hazard detection system contention starts the scene of the chance of its self-management sound test.This Process is similar to these equipment are attempting how to carry out clear channel assessment (CCA) before transmission packet on fiber optic network.In step 1110, the first system can receive the instruction for the sound test for starting at least buzzer.In step 1120, the first system can connect Enter the fiber optic network being present between multiple hazard detection systems.Fiber optic network can be similar to Fig. 6 fiber optic network 600. Step 1130, whether the first system, which can be assessed to have been received by fiber optic network, represents that any other hazard detection system is worked as The preceding packet for whether carrying out sound inspection.For example, if another system is carrying out sound test, it has previously existed Transferred on fiber optic network notify another system its carrying out the packet of sound test.Packet can include various data, all When such as indicating initially to transmit packet or it is expected when to terminate the timestamp of selftest.

In step 1140, if assess instruction currently carries out sound inspection without other hazard detection systems, the One system can perform clear channel assessment (CCA), and if channel idle, then on fiber optic network broadcast packe to indicate first Hazard detection system carries out sound inspection.The first system can be with the repeated broadcast packet.Packet can include some fields. For example, it can include the source field of the initiator of identification packet, which hazard detection system of specified fiber optic network is to be connect The destination field of the intended recipient of the message of receipts and the information field for specifying the information relevant with sound inspection.

If channel is not idle, before attempting to broadcast its packet, the first system can be waited untill channel idle. In addition, if passage is not idle, the first system can first check whether to receive packet, and this indicates another hazard detection system Carry out sound inspection.In step 1150, the first system can carry out self-management sound test, and be surveyed completing sound After examination, the repeated broadcast of the packet can stop.If desired, the first system, which can transmit instruction, has completed the test of its sound Optical fiber message.

Figure 12 shows to be used to carry out self pipe in the system including loudspeaker, buzzer and microphone according to embodiment Manage the example process 1200 of sound test.The target of self-management sound inspection is to check loudspeaker, buzzer and microphone Whether work and (that is, operated with appropriate loudness and frequency).In step 1210, system can instruct loudspeaker and buzzer to connect Even send loudspeaker audio signal then buzzer audio signal.The signal sent can be designed to pleasant as much as possible (or harmless), to make great efforts to provide the optimal Consumer's Experience of sound test (if it user be present by chance during test). The system can provide the signal (herein referred as " boop ") that will be played by loudspeaker and another by being played by buzzer (herein referred as " Bip ", wherein, two signals all generate microphone signal to signal.

Ambient noise, including simultaneously carry out selftest other hazard detection systems and notable reverberant ambiance in one Individual or multiple systems are that can cause the factor of error result.In general, such ambient noise will have addition and convolution The mixing of component.In addition, the gain of microphone can have the noise changed between different system and linear characteristic.In an implementation In example, sound test can generate two boops on a speaker, and two Bips are generated on buzzer.In one embodiment In, the sequential of these signals is fixed, and is contemplated to be in most of environment, and sound test can be by its signal and (bag Including other harm systems) noise in environment makes a distinction.In another embodiment, signal parameter can somewhat change, especially It is that time interval between each boops and each bips can change.These changes turn to sound test and provide different characteristic, and Allow other signals of the sound test signal in signal or like environment of the refusal from the other systems for performing sound test.

In certain embodiments, using both loudspeaker and buzzer.If self-oscillating circuit, buzzer amplitude may It is non-adjustable.In one embodiment, the sequence of four tones can be used in sound test.That is, can be from raising one's voice Device sends two tones, and two tones are sent from buzzer.Speaker can be selected to transfer to represent the octave risen, and honeybee Ring device tone can be selected as short but be enough to ensure that buzzer circuit starts, and no longer need buzzer tone to reduce The Consumer's Experience of undesirable buzzer.This four pitch sequences can grammatically be referred to as " boop boop Bip Bip ", it is boop1, boop2, Bip1, Bip2 more precisely.It will be appreciated that the phase can be provided using other pitch sequences The Consumer's Experience of prestige.

Figure 13 shows the exemplary time diagram for boop1boop2Bip1Bip2 sequences.It sequentially show loudspeaker Tone boop1 and boop2.They can be the sine wave at a distance of octave (for example, with the boop1 of D5 (587Hz) sounding and with D6 The boop2 of (1174Hz) sounding).Attack to boop1 starts after time t1, and the attack to boop2 is after time t 2 Start.Time t2 can change to strengthen the suppression of error signal.Sampling rate for selftest signal transacting can be 8kHz.Based on the frequency, boop1 can be arranged to frequency Fs/14 (=571.42Hz) and boop2 is arranged to Fs/7 (=1142.85Hz).Although these frequencies are the about flat (quarter of a quarter tone for D6 to D5 relative to tone Tone flat), but still retain octave relation, bring pleasant harmless Consumer's Experience for most of users.Relatively low Tone is less than the nominal 700Hz f0 of loudspeaker, and the loss for being about 4dB is presented.In one embodiment, can generate in real time Boops, instead of pre-recorded waveform.In another embodiment, boops can be pre-recorded waveform.The Hes of boop 1 The boop 2 combination duration can cross over time t3.

Figure 13 also illustrates successively buzzer the tone Bip1 and Bip2 different from loudspeaker tone.Buzzer, which can be used in, to shake Swing in circuit, the parameter that can uniquely adjust be buzzer oscillator open duration and Bips before, between and it The duration of mute interval afterwards.In one embodiment, due between system processor 510 and safe processor 530 Time delay, after the time t 4, Bip sequences can be initiated, this can represent that existing interprocedual prolongs between boops and Bips Late.Bip1 can be opened time t5 duration, and Bip can be opened up to t7 duration, t7 by it is variable when Between t6 separate.Time t6 can change to strengthen the suppression to error signal.

Referring again to Figure 12, in step 1220, it can be estimated that sending loudspeaker audio signal and buzzer audio signal phase Between, the energy that is monitored by microphone, whether to evaluate loudspeaker and buzzer by the sound inspection of self-management.Spectrum analysis Instrument can be used for the frequency and amplitude for assessing the audio signal sent by loudspeaker and buzzer.Loudspeaker audio signal and buzzer The assessment of audio signal can be divided into different Digital Signal Processing tests.For example, it can be held independently of buzzer test Row loudspeaker is tested, and the result of each test can be reported as into single test result.It is now discussed with the two tests. Specifically, Figure 14 discusses that example loudspeaker test and Figure 15 discuss exemplary buzzer test, and Figure 14 and 15 can With reference picture 16 and 17, it shows the different filtering and software processing configuration tested according to each embodiment.It is brief first Ground describes Figure 16 and 17 to provide the context of the discussion to Figure 14 and 15, and Figure 16 and 17 will suitably be more fully described.

Figure 16 is shown according to embodiment available for the exemplary of the wave filter and processing arrangement 1600 for carrying out sound test Block diagram.Arrangement 1600 can include microphone signal 1601, analog-digital converter (ADC) 1602, digital filter cascade 1610, it is low Bandpass filter 1614, segmentation wave filter 1618, first assess path 1620, second assess path 1630, high-pass filter 1615, Time domain energy estimator path 1660 and frequency domain energy and frequency estimator path 1670.

Figure 17 shows to be shown according to the wave filter that can be used for carrying out sound test and the another of processing arrangement 1700 of embodiment Example property block diagram.Arrangement 1700 can include microphone signal 1701, analog-digital converter (ADC) 1702, first assesses path 1720, Second assesses path 1730, time domain energy estimator path 1760 and frequency domain energy and frequency estimator path 1770.

Figure 14 show according to embodiment be used for test loudspeaker whether the example process 1400 of normal work.From step 1410 start, and when microphone monitors loudspeaker audio signal, can receive microphone signal, speaker from microphone Frequency signal is characterized as being with multiple tones.For example, loudspeaker can send boop1 and boop2 tones as described above, but should manage Solve, any number of tone can be sent.In step 1420, the microphone signal received can be filtered into multiple assessment roads Footpath, wherein, each assessment path is associated with a tone.For example, in figure 16, segmentation wave filter 1618 will can be received Microphone signal be divided into the first assessment path 1620 and second to assess path 1630.As indicated, segmentation wave filter 1618 will Microphone signal is divided into two discrete assessment paths (being each used for a tone), it is understood that segmentation wave filter 1630 It may be configured to microphone being divided into any number of assessment path, believe depending on how many tone are issued for loudspeaker audio Number a part.Segmentation wave filter 1618 can separate the filtering wheat filtered by cascading filter 1610 and low pass filter 1614 Gram wind number.Cascading filter 1610 can include as analog-digital converter hardware a part and including programmable digital filter Ripple device (for example, notch filter).When positive test loudspeaker, wave filter 1610 can be programmed with the first configuration, and be worked as During positive test buzzer, it can be reprogrammed with the second configuration.Low pass filter 1614 can filter out assessment path and lose interest in Out of band signal.For example, low pass filter 1614 can suppress the buzzer sent from adjacent hazard detection unit.

Simple to refer to 17, each assessed in path 1720 and 1730 directly can receive microphone from ADC 1702 Signal.Path 1720 and 1730 can each include what is be tuned exclusively for a tone in the tone sent by loudspeaker Wave filter (is shown as wave filter 1721 and 1731).Wave filter 1721 and 1731 can be that for example operation is discrete Fu of single-frequency In leaf transformation Goertzel wave filters.

Referring again to Figure 14, in step 1430, the filtered microphone signal in each assessment path can be performed Envelope detected.For example, in arrangement 1600, can be by checking the absolute value of wave filter microphone signal (in element 1621 Place), first order recursive smooth function is applied to the signal (element 1622), and the downsampled signal at element 1623, hold Row envelope detected.As indicated, the second assessment path 1630 can include the element similar with path 1620.

In step 1440, minimum range point can be performed on the filtered microphone signal in each assessment path Class, whether meet that minimum range determines standard with the tone for determining associated with path.During the step, process 1400 can be with Assess filtered microphone signal and expected signal have it is more close.When between the two poor minimum, then loudspeaker is being inferred just It really have issued the tone.For example, in arrangement 1600, can be based on the signal and benchmark to down-sampling at element 1624 (element 1629) calculates least absolute value distance.Minimum distance calculation can be performed in step 1625.Use arrangement 1600 Advantage is It is not necessary to calibration.

Arrangement 1700 can also determine minimum range to determine whether tone matches expected profile distribution curve.This is by member Part 1722-1724 and 1732-1734 show that thus, the filtered microphone signal of down-sampling is compared with stencil function with determination Whether minimum range is obtained.As an alternative, arrangement 1700 can abandon minimum range determination and perform threshold testing (such as 1725 Hes Shown in 1735) to determine whether loudspeaker correctly operates.

Figure 15 shows the example process 1500 for being used for test buzzer and whether working according to embodiment.From step 1510 Start, when microphone is just monitoring buzzer audio signal, microphone signal, buzzer audio signal can be received from microphone It is characterized as with the multiple Bips occurred in same frequency range.For example, buzzer can operate between 3-3.5kHz. Step 1520, the time domain energy of received microphone signal can be estimated.For example, in arrangement 1600, can be from the warp of buffering The microphone signal of filtering obtains time domain energy.That is, can by wave filter cascade 1610 filtering microphone signals with The the second filtered microphone signal filtered by high-pass filter 1615 is provided.High-pass filter 1615 can suppress and buzzing The incoherent out-of-band noise of device signal.Second filtered microphone signal is provided and obtains triggering path 1660 to buffer, it can So that smooth function (element 1662) to be applied to the absolute value (element 1661) of secondary signal.It is then possible to should by secondary signal For making the sample (for example, signal with the amplitude beyond 110dbSPL) more than threshold value be delivered to the threshold triggers of buffer Device (element 1663).The sample of storage in a buffer can be used to estimate the time domain energy of buzzer audio signal.Figure 17's Arrangement 1700 can estimate the time domain energy of buzzer audio signal by assessing the microphone signal received from ADC1702.

In step 1530, the frequency domain energy of received microphone signal can be estimated.For example, in figure 16, Ke Yi Frequency domain energy is obtained in frequency domain energy and frequency estimator path 1670.Can buffer the second filtered microphone signal ( At element 1671), and sample therein can be will be contained in and be applied to DFT (at element 1672), its is defeated Go out can be used for estimate frequency domain energy (at element 1673).In fig. 17, can be in frequency domain energy and frequency estimator path Frequency domain energy is obtained in 1770.Path 1770 can include wave filter group 1771, its frequency range in buzzer audio signal Upper several discrete Fourier transform results (including each wave filter of the group has a result) of generation.These knots can be based on Fruit obtains frequency domain energy.

In step 1540, the frequency of received microphone signal can be estimated., can be by finding in arrangement 1600 The peak frequency exported by element 1672 determines the frequency of buzzer audio signal (at element 1674).Similarly, in cloth In putting 1700, Frequency Estimation can be obtained from wave filter 1771.

In step 1550, can by the time domain energy of estimation compared with the frequency domain energy estimated, with determine they whether In mutual fixed percentage, as shown in element 1780 (but being omitted from Figure 16, to avoid being crowded with the figure).It can be somebody's turn to do Compare to verify detected time domain and frequency domain energy whether in band.For example, if time domain and the energy of frequency domain estimation are at that Within this predetermined percentage, then they are considered in band and buzzer normal operating, otherwise may be considered that It is that the operation of outside band and buzzer is abnormal.

In step 1560, it is determined that the frequency of estimation whether buzzer audio signal frequency range fixed percentage It is interior.The determination is shown (but in order to avoid being crowded with figures, being omitted from Figure 16) in element 1790.Whether determination checking buzzer Operated in the preset range of acceptable buzzer operating frequency.If operated in predetermined scope, buzzer can be with It is considered as to be operated with correct frequency, if it is not, being then not considered as operating with acceptable frequency.

The above-mentioned discussion relevant with Figure 14-17 depends on the signal picked up by microphone.It should be understood that with reference to Figure 14-17 The concept instructed can be used to the behaviour of two or more buzzers in the buzzer that checking operates in hazard detection unit Make.For example, buzzer can be with 520Hz or so sounding with about 3kHz or so sounding, another buzzer.In other realities Apply in example, microphone may not necessarily verify the operation of buzzer and/or loudspeaker.In addition, from the angle of privacy, user may wish Hope mute microphone (MIC) with their impression of enhancing.It is now discussed with verifying the operation of buzzer and/loudspeaker using microphone Various alternatives.

In one approach, the operation of buzzer can be verified using onboard sonac.Although sonac It is generally tuned with the detection signal (e.g., from about 40kHz) of the normal range (NR) higher than human auditory, but it can pick up buzzer 3-3.5kHz fundamental frequencies higher harmonics, so as to verify its operation.Therefore, whether hazard detection system can test its siren With appropriate loudness sounding, and without using microphone.Because buzzer is really very loud (for example, more than 85 decibels), therefore it is easy to Strong sound and electromagnetic signal are generated in other sensors.In one embodiment, buzzer can be in 85dB@3m Place, with 3kHz frequency sounding.Ultrasonic transducer (it can be used for other purposes in hazard detection system) can be with tuned To send and detect 40kHz signal.When buzzer sounding, the 11st and the 12nd subharmonic of big acoustic sound (33kHz and 36kHz) all in the detection range of ultrasonic transducer.Buzzer can have complicated (full harmonic wave) waveform, thus, the 11st, 12nd and harmonic wave thereafter it is also quite loud, therefore, ultrasonic transducer can verify buzzer appropriate during sound checks Loudness operation.Advantageously, transducer need not add circuit explicitly indicates that buzzer just in sounding.(remarks)

In another approach, can be operated using accelerometer to verify buzzer with appropriate sound level.Due to Buzzer can produce vibration with very high sound pressure level sounding with hazard detection system.Accelerometer can detect this Vibrate and provide the signal for representing vibration.Can with assessment signal with determine buzzer whether normal work.

In another method, in wherein having the hazard detection system of two buzzers, buzzer can be by As " microphone ", and another buzzer sends alarm, and vice versa.Equally, because the acoustic pressure sent by two buzzers Level is very high, and the acoustic energy sent by a buzzer can be detected by another detector.The concept can be extended to more The situation that individual hazard detection system is present in structure.First hazard detection can make in its buzzer and the second hazard detection system Buzzer sounding, or vice versa it is as the same.In the case of the extension, because the buzzer in two systems is all tuned to send Signal in same Typical ranges (such as 3-3.5kHz), so they can preferably identify mutual resonant frequency.

In another method, hazard detection system can be utilized and is located remotely from the equipment of hazard detection system positioning The use of microphone.For example, the mobile device of such as phone has microphone.When performing sound inspection, hazard detection system (for example, using Bluetooth Low Energy agreement) establishes with mobile device to communicate and instructs it to monitor by loudspeaker and/or buzzer The sound sent.Mobile device can monitor sound and assess them to be passed through to determine that sound checks whether.As an alternative, it is mobile Equipment can record the sound sent by harm system, and provide it to service for further assessing and reporting.

, can be to cause identical (or the class of the sensory experience of occupant in another method that enhancing suppresses ambient noise Like) mode change the parameter of boop1, boop2, Bip1, Bip2 signal, but each example of signal is different enough, with The robust for the stimulation and ambient noise that can cause the self-management of error result is allowed to distinguish.The signal parameter that can change includes The frequency of signal, be applied to modulating on signal, the frequency spectrum of each independent signal and each signal each part it is relative Duration, attack, maintenance and the decay of such as each signal.In practice, by between each period for changing signal Duration is easiest to utilize the benefit, the duration between such as boop1 and boop2 beginning period, or similarly, Bip1 and Bip2.The signal parameter selected by change can by fixed scheduling, the scheduling received from fiber optic network or The change determined for example, by the calculation device of pseudorandom number generator is dispatched to change.
