Abstract

The present invention provides a safety monitoring device which is provided with a microwave doppler sensor. A microwave doppler frequency shift signal which is output from the microwave doppler sensor is used for calculating the number of body motions and number of breaths. Whether an examined person is safe is monitored according to a combined safe mode above the number of body motions and the number of breaths. Therefore, not only can safe be determined without body movement, but also the state of the examined person can be detected, thereby overcoming the defects in the prior-art safety monitoring device, such as incapability of determining safety at the state of long-time TV watching without large body movement, incapability of detecting abnormity in the healthy state, etc.

Description

Safety is monitoring arrangement whether

Technical field

The present invention relates to whether monitoring arrangement of a kind of safety, to solitary old people etc. separately the personage's of life the unusual etc. of daily animation and health status detect the condition of surveillance summary.

Background technology

In recent years, it is complicated that structure of society is tending towards, and separately the personage of life is on the increase, the for example unmarried person of going to one's post or the local student who lives alone that goes to school easily etc.In addition, social senilization, so-called solitary old people is also increasing.So-called solitary old people is meant the old people who has to live by oneself because of certain origin of an incident.

If relatively younger student or the unmarried person's of going to one's post words; In going to school, going to work or go to the medium chance that contact with other people in way of school or working space more, and the people that existence is got in touch with relative because of reasons such as the contact of household internal are sparse hardly among the solitary old people.These people do not participate in regional activity if be not melted into zone society yet, will occur hardly and outside state of contact.

For the people of independent life, owing to there is not to grasp the people of its personal state at one's side, slow situation such as the affirmation whether frequent unsoundness state and safety wait takes place.Relief postpones to see with the situation that causes miserable result such as solitarily die is quite a few when being suddenly seized with an illness.Particularly solitary old people's age high, the more appearance of this trend.Therefore, in the personage of separately life, particularly the matters whether confirmed with existence of solitary old people's safety become the problem that family and even entire society should address.Technology to said problem has proposed much.

For example, a kind of use infrared ray sensor is disclosed, to nobody being arranged in the room or carrying out the technology (for example, the referenced patent document 1) which kind of activity detects.

Utilize Figure 11 that patent documentation 1 disclosed technology is described.Figure 11 is the block diagram that the structure to patent documentation 1 disclosed technology describes.Shown in figure 11, a plurality of places of living environment recording system 200 in the residence are equipped with the infrared ray sensor 201a-201c that detects the human body that moves in the residence and export signal.

It also possesses information record carrier 206 and communicator 203, constitutes premises control device 207 by them.Said information record carrier 206 not only writes down the temporal information of the signal of infrared ray sensor 201a-201c output, and also record detects place information; Said communicator 203 outputs to order wire 205 with said information record carrier 206 records with each human body detection device time information corresponding and detection place information.

In addition, because according to the safety in the past of having stored mode data and can circulate a notice of more accurately to judge whether, so can constitute the safety monitoring arrangement whether that is rich in reliability.

Can also adopt following structure; The moving device for detecting respiratory of microwave Doppler pick off and body constitutes sensor unit; Safety whether mode decision portion and safety whether device for informing is equipped in the server that has a style of one's own that separates with sensor unit, sensor unit and server are linked up by wired or wireless communication line.

If adopt such structure; Handle the less processing of load through sensor unit; Picture to safety whether each person under inspection's among the monitoring arrangement body moving, breathe that to detect be exactly that so-called less processing is loaded; Other the bigger processing of processing load is to carry out through the server that has a style of one's own that is different from sensor unit, thereby sensor unit can constitute with smaller size according to handling load.

In addition, handle a plurality of data side by side or in batches in order to utilize server, and a plurality of sensor units are combined in the single server, constitute whether monitoring arrangement of safety thus.

Can also adopt following structure, whether information is the moving number of body and said Respiration Rate of time according to the rules to the safety of the moving device for detecting respiratory output of body, and body is moved the result that state and breathing state are distinguished respectively.

If adopt such structure, owing to thisly can realize datumization, only be numerical value (moving number of body and Respiration Rate) so be different from according to the state of distinguishing regulation, can be so that whether intuitively grasp safety.

Can also adopt following structure; Sensor unit is provided with a plurality of; Each sensor unit all has sensor ID (identification: below be also referred to as id number), and each sensor unit will comprise sensor ID and safety, and whether information sends to server in interior data, and server is according to the sensor ID that is included among the data that receive; With the combination particular procedure of person under inspection and sensor unit, whether mode decision portion carries out safety to each person under inspection whether judges through safety.

If adopt such structure; When utilizing 1 server process from data that a plurality of sensor units send respectively; The data of sending, also include and be used for the id number of specific said each sensor unit from each sensor unit; Thereby can grasp the associated in correspondence property of each sensor unit and each data; In addition, as the safety of each sensor unit whether the person under inspection of monitored object stipulated in advance, so the ID of sensor unit and person under inspection's ID be mapped and be stored in advance in the storage part etc. of server; Thereby, can with reference to storage part data and person under inspection be associated in together according to the data (ID that comprises sensor unit is interior) that are input in the server.

Can also adopt following structure; A plurality of sensor units are arranged on place different from each other; Server has data merging portion, and the safety safety whether information combination is got up that the output of this data merging portion will be sent from described sensor unit is information whether, and safety is mode decision portion whether; Input is from the said safety of said data merging portion output information whether, and carries out safety whether to judge and export whether mode data of said safety.

To be a person under inspection in a plurality of places move and the safety that is provided with sensor unit in a plurality of places whether among the monitoring arrangement in prerequisite; Whether only be difficult to carry out suitable safety based on the data from single sensor unit judges; If adopt the structure of above-mentioned that kind; The safety safety whether information combination is got up that data merging portion output will be respectively sent from a plurality of sensor units is information whether; Safety whether the input of mode decision portion from the safety of data merging portion output information (will get up and the safety that obtains information whether) whether from the data combination of a plurality of sensor units; Carry out safety and whether judge and export whether mode data of safety, can obtain whether mode data of suitable safety thus.

Can also adopt following structure, possess: the microwave transmitter of irradiating microwaves; Receive the microwave receiver of echo; Export the microwave demodulator of microwave Doppler frequency shift signal according to echo; Input microwave Doppler frequency shift signal and export the signal processing part of Digital Microwave data, the moving device for detecting respiratory of body possesses: body move count section, and input Digital Microwave data are handled to carry out differential, and output person under inspection's said body is moving to be counted; Respiration detection portion, input Digital Microwave data are handled to carry out FFT, output person under inspection's said Respiration Rate,

The moving count section of body possesses: time differential circuit, and the time rate of change of calculating Digital Microwave data is exported as microwave time rate of change data; The threshold value comparison circuit compares microwave time rate of change data and predetermined numerical value, and the microwave time rate of change data that will exceed predetermined numerical value are exported as the moving signal of effective body; Body moves counting circuit, and the number of per unit time of the moving signal of effective body is counted, and exports as the moving number of body, and respiration detection portion possesses: fft circuit, carry out the FFT conversion and export as frequency distribution data the Digital Microwave data; The first-harmonic testing circuit, incoming frequency distributed data and export and breathe relevant first-harmonic data; The respiratory count circuit is counted and is exported as Respiration Rate the number of per unit time of first-harmonic data.

If adopt such structure; Whether information is detected the safety that obtains based on the microwave Doppler pick off; And according to safety whether information will show the whether whether pattern output of safety of state of safety; Under unusual situation, circulate a notice of, thereby can guarantee really whether safety keeps watch on as notification data.

In addition; Because echo is carried out differential to be handled; The computing oscillation amplitude change is to calculate the moving number of body, and the FFT that carries out echo handles, and the size variation of the frequency content that computing is set is to calculate Respiration Rate; So body that can be accurately that frequency is different is moving and breathe strict the differentiation, can guarantee more really whether safety keeps watch on.

And safety whether information is made up of with Respiration Rate the moving number of body, and safety whether pattern is kept watch on by the moving several and Respiration Rate of body, thereby action that not only can the guarder, and whether the health status that can also keep watch on this person is unusual.

And, can prevent that by the comparison of threshold value noise contribution is by wrong detection.

Can also adopt following structure; Possesses the moving threshold setting portion of the body that makes said predefined change in value; Said threshold value comparison circuit will exceed the said microwave time rate of change data of the numerical value that is changed by the moving threshold setting portion of said body and export as the moving signal of effective body; Possesses the respiration threshold configuration part that to set any number; Said first-harmonic testing circuit according among the frequency distribution data of fft circuit output, intensity exceeds the frequency distribution data of the said numerical value of being set by the respiration threshold configuration part arbitrarily, exports the first-harmonic data.

If adopt such structure; Through to adjusting with respiration threshold configuration part preset threshold by the moving threshold setting portion of body, thus can be with detected moving and breathe the signal that produces and regard noise and remove by body from other persons under inspection beyond the original object of keeping watch on of each sensor unit.

Thereby reducing appears in the safety that can prevent and even suppress the person under inspection whether status detection precision.

Can also adopt following structure, different threshold values is set according to the condition of the microwave Doppler pick off that is set up in moving threshold setting portion of body and said respiration threshold configuration part.

If adopt such structure; Because can be (for example according to the condition of the microwave Doppler pick off that is set up; It the open degree in space that environment promptly is provided with the place, density degree of person under inspection etc. be set) come setting threshold, thereby, can obtain data with the sensitivity that is suitable for its condition.

That is, make predetermined numerical value (threshold value) change of comparing and contrasting through utilizing the moving threshold setting portion of body, thereby can carry out the adjustment of the detection sensitivity relevant with the moving counting of body with the microwave time rate of change.

Thereby; Through reduction detection sensitivity (increasing the situation that threshold value perhaps enlarges the fabric width of threshold value), reduce the noise (from the echo of the acceptor beyond the person under inspection) that utilizes safety the person under inspection's echo (acceptor beyond the person under inspection is positioned near the situation of person under inspection etc.) in addition whether monitoring arrangement is kept watch on to be produced thus from as monitored object; Through improving detection sensitivity (in the situation of the fabric width that reduces threshold value or constriction threshold value), can prevent that thus the detection under the situation far away of the distance from the microwave receiver to person under inspection from omitting.

In addition,, the numerical value arbitrarily that the numerical value with the intensity of first-harmonic data compares and contrasts can be set, thereby the adjustment of the detection sensitivity of first-harmonic data frequency distributed data can be used to detect through the respiration threshold configuration part.

Thereby; Through reducing detection sensitivity (in the situation that increases threshold value), reduce thus the noise (from the echo of the acceptor beyond the person under inspection) that utilizes safety the person under inspection's echo (acceptor beyond the person under inspection is positioned near person under inspection's situation etc.) in addition whether monitoring arrangement is kept watch on to be produced from as monitored object; Through improving detection sensitivity (reducing the situation of threshold value), can prevent that thus the detection under the situation far away of the distance from the microwave receiver to person under inspection from omitting.

Whether mode decision portion judges whether can be one day grade other specified time limit to safety to safety.

If adopt such structure, with regard to the safety rank, it is to stipulate by the accumulation whether safety counts, and but, in general through judging by accumulation one day is so much, can obtain suitable reply.

Can also adopt following structure, whether judge, then be taken as the uneasy judgement of expression during in meeting following (A)-(E) each, when not meeting each, then be taken as the judgement of expression safety based on a plurality of safeties safety whether pattern is carried out,

(A) body is moving unusual lasting more than the 1st time

(B) adnormal respiration continued for the 2nd time

(C) having body to move continued more than the 3rd time

(D) from no body moving and the state more than normal or lasting unusually the 4th time breathed to play no body moving and do not detect and breathe lasting the 5th time

(E) have body moving after, from the 6th time with interior to the 7th time, no body is moving with not detect breathing lasting always.

If adopt such structure; Then can judge whether pattern of safety simply; Be the person under inspection general action model (normal health person's action model: the pattern of " safety " of expression safety in whether), still unusual action model (pattern of " the not safety " of expression safety in whether).Can adopt following content: with the band length of one's sleep, each is inconsistent for the the 1st to the 5th and the 1st to the 7th time length by day.

Generally speaking; Length of one's sleep band (person under inspection is a sleep state) body down is moving and breathe, and is to be that the non-band length of one's sleep (person under inspection is the state of wakeing up) body down moves and the interval of breathing carries out according to being different from daytime, thereby; Through being with the length of one's sleep like this by day; With 5 times of the 1st time to the and set for inconsistently to the time span of the 7th time, by day with length of one's sleep band, the safety that all can the make the person under inspection whether precision of mode data is improved.

Can also adopt following structure, safety whether device for informing possesses the communication monitoring portion of communication function of Department of Communication Force and the monitor communication portion of output notification data.

Through adopting such structure, because whether can keep watch on most important communication function normal, so can constitute the safety monitoring arrangement whether that is rich in reliability.

Through the present invention, because can use moving number of body and Respiration Rate to carry out safety whether supervision, so can high accuracy carry out safety whether supervision.In addition, for the people and solitary old people of independent life, only be difficult for detecting, when body moves and takes place hardly, also can detecting the variation of people's appearance state with the moving detection of body.And, a kind of safety monitoring arrangement whether of unusual, high detection accuracy, the less generation of misidentification of the people's of detecting health status can also be provided.

(embodiment 1)

Below, referring to figs. 1 to Fig. 9 to safety of the present invention whether the embodiment 1 of monitoring arrangement be described in detail.

(schematic illustration of the present invention: Fig. 8, Fig. 9)

At first, use Fig. 8 and Fig. 9 to be installed in safety whether the signal detection principle of the microwave Doppler pick off on the monitoring arrangement describe.Fig. 8 is expression microwave Doppler pick off and person under inspection's a ideograph.Fig. 9 is used for oscillogram that the signal waveform by the microwave Doppler sensor is described.

Among Fig. 8, the 31st, microwave transmitter, the 32nd, microwave receiver, the 33rd, microwave demodulator.Microwave Doppler pick off 3 is made up of them.The 10th, person under inspection, 10a are respiratory muscles.Respiratory muscle 10a is the general name that makes the muscle that thorax enlarges, shrinks when breathing.For example, have diaphragm, internal intercostals, external intercostals, sternocleidomastoid, scalenus anterior, scalenus medius, scalenus posterior, rectus abdominis m., obliquus internus abdominis m., obliquus externus abdominis m., transversus abdominis m. etc.

The microwave Doppler pick off can use common microwave Doppler pick off.In the microwave Doppler pick off; As its output signal analogue signal and digital signal are arranged; Yet, in this embodiment, describing with following embodiment, this embodiment is as shown in Figure 8; The signal that microwave demodulator 33 sends is an analogue signal, and microwave Doppler pick off 3 not install analog signal conversion be the AD converter of digital signal.

Microwave transmitter 31 not only to the microwave M of the about 2.5GHz of person under inspection's 10 emissions, is also exported microwave signal of telecommunication Eme.By the microwave M that microwave transmitter 31 is launched, a part is by the reflection of person under inspection 10 body surface, and another part gets in person under inspection's 10 bodies, and reflection is also received by microwave receiver 32 via person under inspection 10 once more at respiratory muscle 10a place.Microwave receiver 32 not only receives microwave M but also export microwave signal of telecommunication Emr.Microwave demodulator 33 is according to microwave signal of telecommunication Eme and reception microwave signal of telecommunication Emr output microwave Doppler frequency shift signal Ma.

Receive microwave signal Emr and produce the corresponding Doppler frequency shift of action moving with person under inspection 10 body and respiratory muscle 10a, so microwave Doppler frequency shift signal Ma becomes the corresponding signal of action moving with person under inspection 10 body and respiratory muscle 10a.

Characteristic of the present invention is; Analyze said microwave Doppler frequency shift signal Ma; And the moving Arabic formula counting method of use and detection bodies with detect the Arabic formula counting method Arabic formula counting method inequality of breathing, and the integrated mode of breathing moving according to body whether (safety pattern) kept watch on whether safety of person under inspection.

Fig. 9 (a) is presented under 10 of microwave Doppler pick off 3 and person under inspections' the situation of close together (for example 2m), and the time of microwave Doppler frequency shift signal Ma changes; Fig. 9 (b) is presented under its distance situation far away (for example 5m), and the time of microwave Doppler frequency shift signal Ma changes.The difference of distance is that the power through amplitude of wave form shows, but on the variation tendency of waveform, does not have difference.

Interval A-E shown in Figure 9 representes person under inspection 10 breathing state.Interval A is that person under inspection 10 carries out quiet situation of breathing, and shows the situation of the microwave Doppler frequency shift signal Ma that observes the low cycle; Interval B is the situation of breathing fast, the microwave Doppler frequency shift signal Ma that the cycle that observes is faster slightly; Interval C is person under inspection's 10 breathless situation, observes mild microwave Doppler frequency shift signal Ma.

Interval D shows from breathless state to beginning to breathe the quiet situation of breathing of back recovery once more.Identical with interval A, also observe the microwave Doppler frequency shift signal Ma in low cycle.Interval E has the moving situation of body in breathing.For example, the situation of movable health.So, observe the microwave Doppler frequency shift signal Ma that on low periodic component, adds random element.

Example shown in Figure 9 demonstrates the state of breathing from peace and quiet with the medelling mode and quickens to breathing, in case and after respiratory arrest, recover to breathe the situation of movable health again.This example shows the situation of the situation of person under inspection's health generation respiratory variations at the appointed time, just because of safety of the present invention whether monitoring arrangement use the microwave Doppler pick off, so breath state also can be detected.

(action specification of the moving device for detecting respiratory of body: Fig. 2-Fig. 4)

Next utilize Fig. 2-Fig. 4 to safety of the present invention whether the action of the embodiment 1 of monitoring arrangement describe.At first, the action to the moving device for detecting respiratory 5 of body describes.Fig. 3 and Fig. 4 are the oscillograms of the action of the moving device for detecting respiratory 5 of explanation body shown in Figure 2, the transverse axis express time, and the longitudinal axis is represented amplitude.

At first the action to the moving count section 51 of body describes.Fig. 3 (a) shows the Digital Microwave data M d in the time differential circuit 511 be input to the moving device for detecting respiratory 5 of body and is carried out the microwave time rate of change data Dd that time diffusion was handled by time differential circuit 511.Moving signal Cd of the effective body of Fig. 3 (b) demonstration and the relation of being moved number Td by the body of moving counting circuit 513 outputs of body.

Shown in Fig. 3 (a); If the Digital Microwave data M d of input is carrying out differential through time differential circuit 511 by the time;, be the waveform that the center increases and decreases with 0 (zero) then so microwave time rate of change data Dd formation makes a certain amplitude range owing to the time rate of change of signal occurs.

Microwave time rate of change data Dd with compare according to threshold value comparison circuit 512 predefined numerical value, promptly with two threshold shown in Fig. 3 (a) by "+threshold value ", " threshold value " expression, than the big microwave time rate of change data Dd of predefined "+threshold value ", " threshold value " as the effective moving signal Cd of body by 512 outputs of threshold value comparison circuit.In addition, said "+threshold value " reaches " threshold value " and can wait according to experiment in advance and set.

The moving counting circuit 513 of body is the moving number of body Td according to the number of times of moving signal Cd of effective body and the movable health of the 2nd timing signal T2 output unit time.The 2nd timing signal T2 is to be the 5-30 pulse signal of second the pulse period, is the unit interval with 30 seconds for example.In Fig. 3 (b) illustrated embodiment, the unit interval is that the moving number of the body of said 30 seconds (the 2nd timing signal T2) is " 9 ".

Next respiration detection portion 52 is described.Fig. 4 (a) and Fig. 4 (b) show that with the mode of putting Digital Microwave data M d and frequency distribution data F s side by side this frequency distribution data Fs is based on Digital Microwave data M d and by fft circuit 521 outputs.In the figure that shows Digital Microwave data M d, be transverse axis with time, be that the longitudinal axis is represented with the amplitude of signal; In the figure of display frequency distributed data Fs, be transverse axis with the frequency, be that the longitudinal axis is represented with the intensity of signal.And Fig. 4 (a) expression person under inspection 10 does not have the moving situation of body, and Fig. 4 (b) expression has the moving situation of body.

Fft circuit 521 is put aside Digital Microwave data M d at the appointed time based on the 2nd timing signal T2 and is carried out FFT and handle.It is input signal to be carried out FFT handle that said FFT handles.That is, accumulative Digital Microwave data M d is carried out Fourier transform, resolve into each signal component after, each composition is carried out the processing shown in the frequency spectrum, output to first-harmonic testing circuit 522 as frequency distribution data Fs.The 2nd timing signal T2 that puts aside Digital Microwave data M d at the appointed time for example is 30 seconds in the case.

Respiratory waveform comprises everyone inherent harmonic wave, rather than simple sine wave, and, if it is moving also to contain body, then can not detect each waveform in fact.Therefore can adopt following mode to detect, that is: collect actual waveform in the constant time like this and carry out the FFT processing, the fourier spectrometer that resolves into each frequency detects.

First-harmonic testing circuit 522 is according to the frequency distribution data Fs output first-harmonic data Rf of input; Yet; As shown in Figure 4; Be chosen in the frequency distribution of prescribed limit among the frequency distribution data Fs, relevant with breathing, the frequency content that will wherein comprise maximum intensity (peak value) p outputs to respiratory count circuit 523 as first-harmonic data Rf.

That is, first-harmonic testing circuit 522 will be among frequency distribution data Fs the frequency distribution of the scope that is shown as interval R shown in Fig. 4 (a) and Fig. 4 (b), as with breathe relevant composition and take a sample.Two the frequency R1 and the R2 that confirm this interval R for example are the interval of 0.2Hz to 0.5Hz.In addition, frequency R1 and R2's is selected, experimentize to wait and select and can catch and breathe relevant frequency distribution scope.

Because biological respinse has normal distribution property, so in interval R, read composition successively from frequency R1 side.And, if select peak-peak p, can predict that then it is exactly the first-harmonic of breathing.But; Preferred following mode: this moment be not only select single component and peak value the highest as p; If select continuous 2 times in rising trend, and satisfy for the condition of recognized noise more than specific threshold as p, then can obtain the first-harmonic data Rf of higher accuracy.

Fig. 4 (b) shows the moving situation of body, in its waveform, except that comprising the frequency distribution relevant with breathing, also comprises and the moving relevant frequency distribution of body.Will be as the frequency distribution conduct and the moving relevant composition of body of interval T indication range.Confirming two frequency R3 and the R4 of said interval T, for example is the interval of 0.5Hz to 5.0Hz.Said interval T is and the moving relevant frequency distribution of body, so from first-harmonic data Rf, remove.In addition, experimentize etc., frequency R3 and R4 select and can capture and the moving relevant frequency distribution scope of body.Importantly, bigger than the frequency range of breathing as if interval T words are best.In this embodiment, if confirm that the frequency R3 of the interval T words higher than frequency R2 are best.The frequency distribution data Fs after FFT handles do not have clear and definite periodicity because body is moving, so can not occur as clear and definite frequency content.Therefore, among the present invention, as interval T, can get rid of the composition different with breathing through stipulating the moving frequency range of body.

Respiratory count circuit 523 calculates Respiration Rate Rr according to the first-harmonic data Rf of input.That is, through first-harmonic data Rf is enlarged 60 times, the unit of account time is promptly as the Respiration Rate Rr of per minute frequency of respiration.

Whether the action specification 1 of mode decision portion (safety)

Next, to moving according to body and breathe judge safety whether safety whether the action of mode decision portion 6 describe.At first, the judgment standard of body moving number Td and Respiration Rate Rr can use the example shown in following.

Td is as follows for the moving number of body.

The moving number of body Td≤10: " no body is moving "

The moving number of body Td＞10: " having body to move "

The moving number of body Td＞500: " body is moving unusual "

Respiration Rate Rr is as follows.

Detect first-harmonic data Rf at interval R: " breathing normal "

More than frequency R2, detect first-harmonic data Rf: " adnormal respiration "

Do not detect first-harmonic data Rf: " not detecting breathing "

In addition; Distinguish according to moving number of these bodies and Respiration Rate state moving to body and that breathe; Can utilize the moving device for detecting respiratory 5 of body to carry out, in this case, safety whether mode decision portion 6 is carried out following safety based on the differentiation result of moving number of body and Respiration Rate and whether is judged.

Safety whether mode decision portion 6 in order whether to detect safety, a plurality of conditions shown in below using, be safety whether pattern judge the person under inspection safety whether, make whether mode data As of safety.Safety whether pattern shows 5 conditions of A-E.In addition, will be judged to be the N/R state of person under inspection and be called " safety judgement "; There is unusual state to be called " not safety judgement " with being judged to be the person under inspection.

(Mode A)

If " body is moving unusual " continues during time t1, then to be " not safety judgement ".Time t1, for example, be 10 minutes daytime, the band length of one's sleep (night) is 5 minutes.

About above-mentioned Mode A, usually old people is waited in the indoor situation that continues to carry out the strenuous exercise of constant time to be judged as unusually.Selected said time t1 in order to detect this type of situation.

(Mode B)

If " adnormal respiration " continues during time t 2, then to be regarded as " not safety judgement ".Time t2 for example is 10 minutes by day, and being with in the length of one's sleep is 3 minutes.

About said Mode B, usually old people is waited in the indoor situation that continues to carry out the quick breathing of constant time to be judged as unusually.Selected said time t2 in order to detect this type of situation.

(pattern C)

Continue during time t3, then to be regarded as " not safety judgement " if " have body to move ".Time t3 for example is 60 minutes by day, and being with in the length of one's sleep is 10 minutes.

About said pattern C, usually old people is waited in the indoor situation that continues to carry out the body movement of constant time to be judged as unusually.Selected said time t3 in order to detect this type of situation.

(pattern D)

" no body moving " reach after the state that " breathing normal or unusual " continue more than time t4, (to be lower than time t2), continues during time t5, then to be regarded as " not safety judgement " if " no body moves " reaches " not detecting breathing ".Time t4 for example is 5 minutes by day, and being with in the length of one's sleep is 3 minutes.Time t5 for example is 5 minutes by day, and being with in the length of one's sleep is 3 minutes.

About said pattern D, go out as if the person under inspection, so follow temporary " having body to move " or " body is unusually moving " before certainly owing to " detect breathing " to outdoor mobile becoming.Be judged as unusually to the situation that loses breathing suddenly from " no body is moving " state.Said time t4 and time t5 have been selected in order to detect this type of situation.

(pattern E)

" there is body to move " afterwards, in time t6, if " no body is moving " and " not detecting breathing " continue during time t7, then to be regarded as " not safety judgement ".Time t6 for example is 2 minutes by day, and being with in the length of one's sleep is 2 minutes.Time t7 for example is 60 minutes by day, and being with in the length of one's sleep is 20 minutes.

About above-mentioned pattern E, being judged to be after the person under inspection is " have body moving " or " body is moving unusual ", more than the constant time, do not detect the state that body is moving and breathe, it is outdoor also can to think to go out.All do not have to recover as if or breathing moving, then be judged as unusual at constant time endosome.

Frequency content through having carried out Fourier transform detects breathing.Body is moving to be detected through differentiated waveform.Thus, breathe with body is moving and compare,, breathe hardly faults does not take place owing to receive effect of noise.Therefore, detect continuously about what body moved and breathed, body is moving preferential, moves under the continuous nonevent state at body, and one-time detection is regarded as faults to the case of breathing separately, thinks invalid.

Whether pattern defines for " the not safety judgement " of abnormality judging the person under inspection above-mentioned safety, and certainly, then the person under inspection is no abnormal as if the words that do not meet any one, is " safety judgement ".

Safety whether mode decision portion 6 is used whether Mode A-E of above-mentioned safety, carries out safety respectively by set timing and whether judges.For example per 30 seconds.This timing be used for said safety and whether " daytime " and " the band length of one's sleep (night) " of pattern use the 3rd timing signal T3 shown in Figure 2 jointly.Said the 3rd timing signal T 3 is of explaining, has information such as date and time.

Whether be provided with not shown storage part in the inside of mode decision portion 6 in safety, whether Mode A-E is stored in this storage part the safety of above-mentioned explanation.Said safety is pattern whether, except illustrated example, can also select various judgment standards according to person under inspection's characteristics and action model.In addition, several kinds of safeties can also preparing other in advance are pattern whether, according to circumstances uses respectively.

(safety is the action specification 2 of mode decision portion whether: Fig. 5)

Next, utilize Fig. 5 to safety whether other action of mode decision portion 6 describe.Said action is such action, that is since safety whether emergency, the life and death importance degree of pattern is different, whether count so preestablish, and whether 1 day safety counted to add up to whether rank is exported as safety with the corresponding safety of each pattern.

Fig. 5 (a) with a plurality of safeties whether pattern be illustrated in the form with counting of each pattern, the safety of use whether pattern is to use the whether embodiment of Mode A-E of the safety explained.In addition, the safety that Fig. 5 (b) will show emergency is rank whether, the accumulative total whether 1 day safety counts and with it corresponding gerentocratic corresponding tables is shown in the form.

Whether Mode A-E and urgency level are in direct ratio is given safety respectively and whether count for safety; To safety whether Mode A give safety whether count " 3 "; To safety whether Mode B give safety whether count " 2 "; Whether pattern C gives safety whether counts " 1 " to safety, and whether pattern D gives safety whether counts " 10 " to safety, to safety whether pattern E give safety whether count " 5 ".

Whether safety counts is confirmed according to the life and death importance degree.For example, whether the safety of pattern C counts is " 1 ", and Mode A is " 3 ".Pattern C as stated, though " have body moving ", the words that among time t3, continue then are " not safety judgement ".The embodiment of time t3, be 60 minutes daytime, the length of one's sleep, band was 10 minutes.If with the daytime is example, detected the state of " having body to move " at least at 60 minutes.On the other hand,, it would be better to say so violent " body is moving unusual " Mode A is " having body to move ", yet, be situation that (for example, be 10 minutes daytime, and the length of one's sleep, band was 5 minutes) continues in time t1.So owing to compare with Mode A, pattern C is not the moving state of violent body, so whether face life and death from the person under inspection this puts, and can think that the probability of person under inspection's existence (promptly not facing death) is high among the pattern C.According to said judgement, whether pattern is carried out the such importance degree judgement of life and death importance degree to each safety.

Whether pattern preestablishes safety whether counts to each safety, and the safety of confirming according to the aggregate-value whether 1 day safety counts rank whether, for example, set " low ", " in ", " height " 3 stages.If the safety aggregate-value of whether counting for the words of " 1-3 " then safety whether rank is " low "; If the safety aggregate-value of whether counting for the words of " 4-9 " then safety whether rank for " in ", if the aggregate-value whether safety counts for " 10 " above words then safety whether rank is " height ".

Whether rank is the aggregate-value whether safety counts owing to safety, so with Fig. 5 (b) illustrated embodiment, whether the safety of pattern C counts is 1, if said pattern C only took place 1 time at 1 day, then shown in Fig. 5 (b), whether rank is " low " to safety.But, though diagram not, if said pattern C took place 4 times at 1 day, safety whether rank then be " in ", the words that generation in 1 day is 10 times then are " height ".

That is, with misery struggle such " body is moving unusual " compare, cough constantly such " adnormal respiration " possibly be slight unusual, yet, if should " adnormal respiration " repeat to take place at 1 day for several times, possibly be serious unusual rather than mile abnormality.Whether count and safety whether rank through setting safety this moment, and just becoming unusually of person under inspection distinguished easily.

In addition; Also can whether rank be confirmed attribute according to safety; The safety whether attribute of rank " low " is " confirming according to image information ", safety whether rank " in " be " direct session is confirmed through conversing ", whether rank " height " is " access confirmation " to safety.Attribute " access confirmation " is preferably to visit at once to confirm safety whether situation, and attribute " is confirmed according to image information ", " direct session is confirmed through conversing " can be in the situation that does not have such emergency.These attributes are enrolled safety whether among the mode data As.

About after the safety stated device for informing 7 whether; If the safety whether content of mode data As is to be judged to be the person under inspection unusual " not safety judgement " arranged; Then safety whether the content of mode data As send as notification data N by Department of Communication Force 73, at this moment, also can obtain the whether information of rank and attribute of safety if receive management of information person; Whether suit to go the person under inspection to visit at once at one's side; Still only use communicator 82 to wait and can wait to person under inspection's inquiry " whether have unusual ", the such a material of judging increases some more, the judgement of then being more convenient for.

At preceding text, with regard to a plurality of safeties whether pattern number, and give each safety whether pattern give whether safety counts and safety whether grade other number is illustrated, but be not limited thereto, can set according to person under inspection and surrounding.

(safety is the action specification of device for informing whether: Fig. 2-Fig. 4)

Next, to safety whether the action of device for informing 7 describe.From the safety safety mode data As whether of mode decision portion 6 outputs whether, in case be stored in the storage part 71, then whether pattern storage data Sd reads from storage part 71 as safety, and is outputed to circular judging part 72.Circular judging part 72 judges whether whether pattern storage data Sd is the rank that needs circular to the safety of being imported.

Lift an example, if safety whether the content of mode data As be to be judged to be the person under inspection not have unusual " safety judgements ", then be judged as and need be not the rank circulated a notice of.In addition, if safety whether the content of mode data As be to be judged to be the person under inspection unusual " not safety judgement " arranged, then with safety whether the content of mode data As add and output circular index signal Ed to circular index signal Ed.

Circular index signal Ed sends to the outside as notification data N by Department of Communication Force 73.As Department of Communication Force 73, can take digital modulator and the combination that is connected to the electric wire control device of regular phone line, also can adopt the analog or digital radio transmitters.

(outward appearance explanation: Fig. 7) next, use Fig. 7 that the whether outward appearance of monitoring arrangement 1 of safety is described.81 is display in Fig. 7, the 82nd, and communicator, they are the important documents that constitute device for informing 8.83 and 84 is console switchs.As shown in Figure 7, whether monitoring arrangement 1 has the outward appearance near desk-top photo frame to safety, has taken in microwave Doppler pick off 3 on top, is provided with display 81, communicator 82 and the console switch 83,84 of device for informing 8 at front surface.

Display 81 can use liquid crystal display.As described, according to from the safety safety content of mode data As whether of mode decision portion 6 outputs whether, can show " having unusual? " Deng literal.

Communicator 82 can constitute by send ceramic audio device or the dynamic speaker that sound as " whether have unusual " carries out inquiry to the person under inspection.

In addition, safety whether monitoring arrangement 1 also is mounted with the communicator that can receive conversation when answering etc. from the person under inspection, so communicator 82 can be made up of the combination of ceramic audio device or dynamic speaker and moving coil microphone.

Console switch 83,84 is used for the displaying contents and the volume of display 81 are operated, and perhaps to replying from the inquiry of communicator 82, can use the switch of button-type.For example; For the inquiry as " whether having unusual " from display 81 or communicator 82; When the person under inspection has no problem, through in official hour, console switch 83 or console switch 84 being operated etc., person under inspection's state is input to whether monitoring arrangement 1 of safety.

(explanation of the motion flow of embodiment 1: Fig. 2, Fig. 6)

Below, use Fig. 2 and Fig. 6 to specify the whether motion flow of monitoring arrangement 1 of safety.Fig. 6 is the whether motion flow of the action of monitoring arrangement 1 of explanation safety.Below be described in detail.

S1 is the program that reads signal.With microwave Doppler frequency shift signal Ma according to resolution 10bit, convert Digital Microwave data M d to the sample rate of about every 10msec.(S1)

S2 is the macroprogram according to the moving number of Digital Microwave data M d output body Td.Below be described in detail.

The Digital Microwave data M d that will pass through sampling is to be expressed as V (n) the n time according to the sampling number of times, and time diffusion is undertaken by being described below.

Δ V=V (n)-V (n-1) calculates receding diffierence (Δ V) with the numerical value of front one sampling.(S21)

Come the moving aggregate-value of body is counted by following two conditions.(S22) Δ V＞0.05V (being equivalent to+threshold value), Δ V≤0.05V (being equivalent to-threshold value), this numerical value of said 0.05V is threshold value, this is an example.Owing to need not consider to be provided with the environment noise of the environment whether safety install, and wait to confirm through experiment.

30 seconds these a part of Wave datas are stored among the array V (n); In addition, export the moving number of the body Td in 30 seconds.(S23)

Judge according to the moving number of 30 seconds bodies.(S24) if the moving number＞10 of body then judges it is " having body to move "; If the moving number≤10 of body then judges it is " no body is moving ".If＞500 judgements of the moving number of body are " body are moving unusual ".

S3 is the mastery routine of output Respiration Rate Rr.Digital Microwave data M d between 30 seconds carries out the FFT conversion.First-harmonic data Rf according to extracting out breathes judgement.(S3) in interval R (more than 0.2Hz, be lower than 0.5Hz), detect first-harmonic data Rf, then be judged to be " breathing normal ".More than frequency R2 (0.5Hz), detect first-harmonic data Rf, then be judged to be " adnormal respiration ".If do not detect first-harmonic data Rf, then be judged to be " not detecting breathing ".

S4 judges safety whether mastery routine.Export whether mode data As of safety according to the moving number Td of the body during 30 seconds and Respiration Rate Rr.In addition, according to the safety content of mode data As whether, propose as inquiries such as " what's the matter " to person under inspection 10 through device for informing 8.(S4)

S5 is the program that is stored in the data file of storage part 71.Result and date and time between 30 seconds together are kept in the data file of 24 hours forms.In addition, except that date, time, the moving number of body, the moving number of body cumulative number, Respiration Rate etc., also store the respiratory frequency distribution value as required, breathe the wave spectrum value.(S5)

S6 is the program of circulating a notice of and showing.According to safety whether pattern storage data Sd content, or, under urgent situation, send notification data N as required with reference to the safety in the past content of pattern storage data Sd whether.(S6)

Through above step, can overcome the shortcoming of existing mode, while for example when not have more moving such sleeping to watch TV for a long time etc., be difficult to the person under inspection is produced detect unusually, perhaps detecting unusually to health status.

(embodiment 2)

(safety is the structure explanation of monitoring arrangement whether: Figure 10)

Next, utilize Figure 10 that the whether embodiment 2 of monitoring arrangement of safety is described.Whether the safety of monitoring arrangement 100 is whether among the device for informing 7 in the safety relevant with embodiment 2, and also being added with the function that is used for monitor communication portion 73 is the normal communication monitoring 73a of portion, and whether the monitors for activity reliability is higher thereby make safety.

Figure 10 be show safety whether monitoring arrangement 100 the functional block diagram of structure, only express as the safety of the important document that is different from embodiment 1 whether device for informing 7a and relevant device for informing 8.

Whether the 73a of communication monitoring portion of device for informing 7a is to Department of Communication Force 73 output functions maintenance signal Hk for safety, and whether the function of differentiating Department of Communication Force 73 is normal.Particularly, function overhaul signal Hk is the test program that makes Department of Communication Force 73 analog operation.Although this test program less than diagram, is provided with storage part and is stored in the 73a of communication monitoring portion.

If the abnormal words of function of Department of Communication Force 73, then the 73a of communication monitoring portion outputs to device for informing 8 with caution signals A1.Device for informing 8 shows from the caution signals A1 of the 73a of communication monitoring portion input by display 81, and through communicator 82 sound that gives a warning, and notifies person under inspection 10 and with the relevant personnel of person under inspection 10.Because other important document in the 2nd embodiment is identical with the 1st embodiment, so multiple explanation is omitted.

(the effect explanation of embodiment 2)

The safety whether most important function of monitoring arrangement is to keep watch on safety whether function and information is sent to outside function.For the people of independent lives such as solitary old people, be the important document that is equivalent to unique safety belt with outside contact.Even safety whether monitoring arrangement can correctly be kept watch on person under inspection's state, still, whether device for informing can not works fine then have no meaning if be used for that its situation is delivered to outside safety.For this reason, if communicate the supervision of function through communication monitoring portion, we can say safety whether the reliability of monitoring arrangement further improve.

Above-mentioned illustrated example is not limited thereto, if satisfy purport of the present invention, much less can change arbitrarily.

(embodiment 3)

(structure that is divided into sensor unit and server)

Whether monitoring arrangement 1,100 can form following structure to the safety of above-mentioned each embodiment: shown in figure 12; The moving device for detecting respiratory 5 of microwave Doppler pick off 3, signal processing part 4, timing portion 9 and body constitutes as integral sensor unit 300; Safety whether mode decision portion 6, safety whether device for informing 7 and device for informing 8 be provided in the server 400 of opening in 300 minutes with sensor unit and having a style of one's own, sensor unit 300 links by communication line 600 with server 400.

And sensor unit 300 is arranged on particular space, and this particular space for example is to become to rely on whether person under inspection 10 rooms etc. at place usually of the object that monitoring arrangement 1,100 is kept watch on of this safety.

On the other hand, server 400 is arranged on the place that the place is set that is different from sensor unit 300 (place (for example being guard company and hospital etc.) that the safety manager whether monitoring arrangement 1,100 is managed is often treated).

Communication line 600 both can be a Wireline, also radiolink such as WiFi.

Under the situation that communication line 600 employing radiolinks constitute, shown in figure 13, this communication line 600 possesses: wireless transmission part 610, will send as wireless signal from the signal of moving device for detecting respiratory 5 outputs of the body of sensor unit 300; Wireless receiving portion 620, the wireless signal of reception 610 transmissions from the wireless transmission part converts wire signal and output to; Circuit such as the Internet and LAN 640 makes from the signal circulation of wireless receiving portion 620 outputs; Data reception portion 630 reads in mobile signal in the circuit 640.

Herein; Wireless transmission part 610 is wholely set in sensor unit 300; And be transfused to dateout (the moving number of body Td, Respiration Rate Rr) from the moving device for detecting respiratory 5 of body and the dateout (the 3rd timing signal T3) of coming self clock portion 9, become wireless signal to send these data transaction.

On the other hand, data reception portion 630 is arranged in the server 400, and will be input to safety from the data (the moving number of body Td, Respiration Rate Rr, the 3rd timing signal T3) of circuit 640 input whether the mode decision portion 6.

The moving number of body Td, Respiration Rate Rr from moving device for detecting respiratory 5 outputs of the body shown in the embodiment 1; It is the initial data of the moving number of detected body, Respiration Rate in the unit interval; Yet; In following embodiment, the moving number of body Td becomes the data that are divided into " body is moving unusual ", " having body to move ", " no body is moving " 3 kinds of situations (branch rank); Respiration Rate Rr becomes the data that are divided into " adnormal respiration ", " breathing normal ", " not detecting breathing " 3 kinds of situations (branch rank).

In addition, above-mentioned 3 kinds of divisions of the moving number of body Td are defined as with identical in the division shown in the embodiment 1:

When more than frequency R2, detecting first-harmonic data Rf " adnormal respiration "

" do not detect breathing " when detecting first-harmonic data Rf.

In addition, wireless receiving portion 620 is arranged in the scope of the distance that can receive the wireless signal that sends from wireless transmission part 610.

If utilize the safety monitoring arrangement 1,100 whether among the embodiment of above-mentioned formation; Except effect with the above embodiments 1,2; Can also utilize sensor unit 300 to carry out the less processing of processing duty ratio as the body that detects person under inspection 10 moves, breathes; Utilize the server of opening in 300 minutes with sensor unit that has a style of one's own 400 to carry out other and handle the bigger processing of duty ratio, thereby sensor unit 300 can constitute with smaller size according to the needs of handling load.

(structure) with a plurality of sensor units

And, in order to utilize the parallel or a plurality of data of batch process of server 400, and a plurality of sensor unit 300,300...... etc. are combined in the single server 400, constitute whether monitoring arrangement 1,100 of safety thus.

Promptly; Shown in figure 14; In the ward in hospital the multidigit patient is arranged, each patient is regarded as person under inspection 10 (the person under inspection 10B of the person under inspection 10A of bed A, bed B) respectively, and sensor unit 300A, 300B are to be provided with (the corresponding person under inspection 10A of sensor unit 300A, the corresponding person under inspection 10B of sensor unit 300B) with person under inspection 10A, 10B corresponding mode respectively; In said ward, only equip a wireless receiving portion 620; LAN in the ward is taken as circuit 640, possesses the single server 400 that is arranged in the hospital, thus through said structure to constitute whether monitoring arrangement of safety of the present invention.

In this case; Since the safety in the server 400 whether mode decision portion 6 need to differentiate from the data of data reception portion 630 inputs among two person under inspection 10A, 10B be belong to person under inspection 10A, still belong to the data of person under inspection 10B; So; Make respectively and person under inspection 10A, each sensor unit 300A, 300B that person under inspection 10B is corresponding; In its each wireless transmission part 610, have for example ID (identification) number that is used for sensor unit 300 particular procedure respectively, the data that each wireless transmission part 610 is sent (the moving number of body Td, Respiration Rate Rr, the 3rd timing signal T3) are added said id number, for example are sent out as header.

On the other hand; Object log-on message storage part 800 in server 400, is equipped with; This object log-on message storage part 800 will be set up corresponding relation with person under inspection 10A, person under inspection 10B corresponding to each sensor unit 300A of person under inspection 10A, person under inspection 10B, the information of 300B particular procedure (for example above-mentioned id number), stored as the object log-on message; And, be input to safety whether in the mode decision portion 6 with storing object log-on message in the object log-on message storage part 800 into.

And; If data are input to safety respectively whether the mode decision portion 6 from each sensor unit 300A, 300B; Then whether mode decision portion 6 reads the id number that is added as header that is input into data to safety; Thereby, as being used for judging with data by the corresponding person under inspection 10A of the id number of object log-on message particular procedure, 10B.

In addition; Sensor unit 300A, 300B each with a people person under inspection 10A, 10B as monitored object; Yet; As shown in figure 14 when having multidigit person under inspection 10A, 10B to treat in a ward, under the situation of near the person under inspection 10A that also has other the person under inspection 10A of monitored object, the 10B, 10B, each sensor unit 300A, 300B; Except that possibly detecting person under inspection 10A as original monitored object, microwave reflection that 10B sends (microwave M that is reflected by person under inspection 10A, 10B), also might detect original was not other person under inspection 10B of monitored object, the microwave reflection that 10A sends just.

And, not other person under inspection 10B of monitored object, the microwave reflection that 10A sends just in case also detect original, probably can not correctly detect whether safety of person under inspection 10A as original monitored object, 10B.

For this reason in the safety of each embodiment whether in monitoring arrangement 1 grade; All can take following mode: shown in figure 15; In each sensor unit 300, be equipped with the moving threshold setting portion 531 of body; The moving threshold setting portion 531 of this body makes the predefined numerical value that is illustrated among Fig. 3 (a), be threshold value (+threshold value and-scope between the threshold value) change; In addition, threshold value comparison circuit 512 will exceed the numerical value that changes by the moving threshold setting portion 531 of body (+threshold value and-scope between the threshold value) microwave time rate of change data export as the moving signal of effective body; Outfit can be set the respiration threshold configuration part 532 of the threshold value of any number shown in Fig. 4 (c); In addition; First-harmonic testing circuit 522 according among the frequency distribution data Fs of output from fft circuit 521, intensity exceeds the frequency distribution data F s by respiration threshold configuration part 532 preset threshold, exports first-harmonic data Rf.

Herein, by the moving threshold setting portion of body 531 preset threshold, be in order will not to be that the person under inspection's of monitored object the moving signal that causes of body is removed as noise and the numerical value confirmed based on experiment fully in advance etc. by this.

That is,, for example can set according to the condition of the microwave Doppler pick off that is set up (particularly, the number of the room-size of setting, the sensor unit that in a room, is provided with, interval etc.) by the moving threshold setting portion of body 531 preset threshold.

In addition, by respiration threshold configuration part 532 preset threshold, be in order to remove as noise and the numerical value confirmed based on experiment fully in advance etc. by this signal that is not the person under inspection's of monitored object breathing causes.

If utilize such structure, utilize the moving threshold setting portion 531 of body that the predetermined numerical value (threshold value) with microwave time rate of change data comparison and contrast is changed, thereby can relate to the adjustment of the detection sensitivity of the moving counting of body; Utilize respiration threshold configuration part 532 that the numerical value arbitrarily (threshold value) with the numerical value comparison and contrast of the intensity of first-harmonic data is changed, thereby can be used to detect the adjustment of detection sensitivity of the frequency distribution data F s of first-harmonic data Rf.

Thereby sensor unit 300A can also suppress the detection of carrying out from the microwave reflection that is not the person under inspection 10B of monitored object originally except that to from as the microwave reflection of the person under inspection 10A of monitored object detects originally; Sensor unit 300B can also suppress the detection of carrying out from the microwave reflection that is not the person under inspection 10A of monitored object originally except that to from as the microwave reflection of the person under inspection 10B of monitored object detects originally.

Thus, can prevent and even suppress the whether reduction of status detection precision of safety of each person under inspection 10A, 10B.

In addition; The adjustment of 532 pairs of threshold values of adjustment and respiration threshold configuration part of 531 pairs of threshold values of the moving threshold setting portion of body; Self-evident also applicable among Fig. 1, the embodiment shown in 2, and and be not only in being partitioned into the structure that sensor unit 300 and server 400 form and just can carry out.

In addition; The adjustment of 532 pairs of threshold values of adjustment and respiration threshold configuration part of 531 pairs of threshold values of the moving threshold setting portion of body; The room-size that can stay according to the person under inspection 10 as the monitored object of sensor unit 300 waits carries out, and is not to only limit in a ward, exist several person under inspections' situation just passable.For example; As moving threshold setting portion 531 preset threshold by body; In the bigger room of area, only there is a person under inspection 10 to exist and plans to detect apart from sensor unit 300 distances under the situation of the scope about 5m, can "+threshold value " be set for+0.1 (V), " threshold value " set for about-0.1 (V).

On the other hand, multidigit person under inspection 10A, 10B are arranged in a ward as stated and plan to detect apart from sensor unit 300 distances under the situation of 1m with interior scope, "+threshold value " can set for+and 1.0 (V), " threshold value " set for about-1.0 (V).In room-size is 6 tatamis (about 10m ²) the apartment in; A person under inspection 10 is only arranged and plan to detect apart from sensor unit 300 distances and (do not planning to detect under other people situation in next door, apartment) under the situation of the scope about 2m, "+threshold value " can set for+1.0 (V) and+value, " threshold value " between 0.1 (V) set the value between-1.0 (V) and-0.1 (V) for.

In addition,, a person under inspection 10 existence are only arranged in very wide room and plan detection under the situation of sensor unit 300, can " threshold value " be set for about 0.5 apart from the scope about 5m as by respiration threshold configuration part 532 preset threshold.

On the other hand, multidigit person under inspection 10A, 10B are arranged in a ward as stated and plan to detect apart from sensor unit 300 distances under the situation of 1m, can " threshold value " be set for about 1.0 with interior scope.In room-size is the apartment of 6 tatamis, only there is a person under inspection 10 to plan to detect apart from sensor unit 300 distances, can threshold setting be become the value between 1.0 and 0.5 (not planning to detect under other people situation in next door, apartment) under the situation of the scope about 2m.

(embodiment 4)

Whether monitoring arrangement 1 grade is that 2 perhaps situation of 10 existence of the person under inspection more than 2 can corresponding be arranged in a space (ward) to the safety of the foregoing description 3; Yet, Figure 16 be corresponding to for example only there being a person under inspection 10 to exist in contrast but use many between the embodiment of situation (Figure 17) in room.Promptly; In general supposition is the situation with personal lifestyle in only dwelling house in two above rooms or the condominium; In this case, be one as the person under inspection 10 of monitored object, but; Shown in figure 17, a plurality of sensor unit 300A, 300B, 300C, 300D are provided with the mode that corresponds respectively to room, bedroom, bathroom, each room of toilet.

Like this; Among each room, be provided with respectively under the situation of sensor unit 300 as a plurality of places different from each other; Because person under inspection 10 only stays in wherein in room, bedroom, bathroom, these rooms of toilet in the specific time; So, if the safety of server 400 whether mode decision portion 6 only carry out safety in the room in and whether judge according to the signal that is arranged on the sensor unit 300 that does not stay in, then probably understand the result of output error.

For this reason; In the safety of the embodiment shown in Figure 16 whether in monitoring arrangement 1 grade; In server 400, be equipped with data merging portion 700; This data merging portion 700 will need the output of the sensor unit 300A-300D of combination to combine corresponding to person under inspection 10, whether information is exported as safety.
