According to such structure, due to irradiating microwaves, its echo produces the doppler shifted signal corresponding to the motion of moving and breathing muscle together with the body of person under inspection, so, if use it to come the dynamic number of detection bodies and Respiration Rate, then reliably can monitor whether safety.
It can be also following structure, has: body moves device for detecting respiratory, exports and to move several safety relevant with Respiration Rate whether information with the body of person under inspection; Safety whether mode decision portion, input safety whether information carries out the safety whether judgement of person under inspection, exports safety whether mode data.
According to such structure, due to result that whether safety is judged as safety whether mode data, the data that namely achieve medelling exported, thus can tackle utilizing the measure of this safety whether after mode data very easily.
Structure can be: safety whether mode decision portion according to safety whether information whether whether pattern is consistent with multiple safety, judge person under inspection's whether safety, export the safety corresponding with safety whether result of determination whether mode data.
According to such structure, when safety whether information and multiple safety whether pattern is consistent, by they being combined, accurately can judge person under inspection's whether safety.
Structure can be: whether mode decision portion carries out judging and exporting safety as follows, that is: whether count for any one setting safety corresponding with the urgency of described person under inspection in described multiple safety whether pattern, be taken as represent no judgement when being consistent with any one in described multiple safety whether pattern, give safety set under each safety whether pattern whether to count, and whether the described safety of giving within specified time limit is counted accumulate, thus judge safety whether rank, and by described safety whether rank read in described safety and whether exported in mode data.
According to such structure, be set to whether to count the urgency of following person under inspection and superposing with safety, the accumulation of whether being counted by this safety and the safety specified whether rank are also stored in safety whether in mode data, thus can carry out the process of the urgency considering person under inspection.
Following structure can also be adopted, there is input safety whether mode data and export the safety whether device for informing of notification data, safety whether device for informing under whether mode data is the situation that safety does not judge in safety, export the notification data comprising safety whether rank, make to confirm that safety whether inquiry content is according to safety whether rank and different based on notification data to person under inspection.

According to such structure, the less process of processing load is carried out by sensor unit, the body of picture to each person under inspection among safety whether monitoring arrangement moves, breathe that to carry out detecting be exactly the less processing load of what is called, the process that other processing load is larger is that the server had a style of one's own by being different from sensor unit carries out, thus, sensor unit can be formed with smaller size according to processing load.
In addition, in order to server can be utilized to process multiple data side by side or in batches, and multiple sensor unit is combined in single server, forms safety whether monitoring arrangement thus.
Following structure can also be adopted, body move safety that device for detecting respiratory exports whether information be the dynamic number of body of time according to the rules and described Respiration Rate, body is moved the result that state and breathing state are distinguished respectively.
According to such structure, because this state according to distinguishing regulation can realize datumization, so being different from is only numerical value (body dynamic number and Respiration Rate), can so that intuitively grasp whether safety.
Following structure can also be adopted, sensor unit is provided with multiple, each sensor unit all has sensor ID (identification: hereinafter also referred to id number), the data comprising sensor ID and safety whether information are sent to server by each sensor unit, server is according to the sensor ID be included among the data that receive, by the combination particular procedure of person under inspection and sensor unit, by safety, whether mode decision portion carries out safety to each person under inspection whether judges.
According to such structure, when the data utilizing 1 server process to send respectively from multiple sensor unit, the id number for specific described each sensor unit is also included in the data of sending from each sensor unit, thus the corresponding relatedness of each sensor unit and each data can be grasped, in addition, person under inspection as the whether safe monitored object of each sensor unit is prescribed in advance, be stored in advance in storage part of server etc. so the ID of sensor unit and the ID of person under inspection is mapped, thus, data and person under inspection can be associated together with reference to storage part according to the data be input in server (comprising the ID of sensor unit).
Following structure can also be adopted, multiple sensor unit is arranged on place different from each other, server has data merging portion, this data merging portion exports the safety safety whether information combination is got up that sends from described sensor unit whether information, safety whether mode decision portion, input the described safety that exports from described data merging portion whether information, and carry out safety whether to judge and export described safety whether mode data.
That a person under inspection to move in multiple place and the safety being provided with sensor unit in multiple place whether among monitoring arrangement in prerequisite, only be difficult to carry out suitable safety based on the data from single sensor unit whether judge, according to structure as described above, data merging portion exports the safety sent from the multiple sensor unit respectively safety whether information combination is got up whether information, safety is the safety that exports from data merging portion of mode decision portion input whether information whether (got up by the data assemblies from multiple sensor unit and the safety that obtains information) whether, carry out safety whether judge and export safety whether mode data, suitable safety whether mode data can be obtained thus.
Following structure can also be adopted, possess: the microwave transmitter of irradiating microwaves; Receive the microwave receiver of echo; The microwave demodulator of microwave Doppler frequency shift signal is exported according to echo; Input microwave Doppler frequency shift signal and export the signal processing part of Digital Microwave data, body moves device for detecting respiratory to be possessed: body moves count section, and input Digital Microwave data, to carry out differential process, export the dynamic number of described body of person under inspection; Respiration detection portion, input Digital Microwave data, to carry out FFT process, export the described Respiration Rate of person under inspection,
Body moves count section to be possessed: time differential circuit, calculates the time rate of change of Digital Microwave data, exports as microwave time rate of change data; Microwave time rate of change data and predetermined numerical value are compared by threshold value comparison circuit, and the microwave time rate of change data exceeding predetermined numerical value are moved signal to export as effective body; Body moves counting circuit, and the number effective body being moved to the per unit time of signal counts, and export as the dynamic number of body, respiration detection portion possesses: fft circuit, carries out FFT conversion and export as frequency distribution data Digital Microwave data; Fundamental current detection circuit, incoming frequency distributed data and export and breathe relevant first-harmonic data; Respiratory count circuit, counts the number of the per unit time of first-harmonic data and exports as Respiration Rate.
According to such structure, whether information is detected the safety obtained based on microwave Doppler sensor, and according to safety whether information by the safety of display safety whether state, whether pattern exports, circulated a notice of as notification data in an exceptional case, thus really can be ensured whether safety monitors.
In addition, owing to carrying out differential process to echo, the change of computing amplitude is to calculate the dynamic number of body, carry out the FFT process of echo, the size variation of the frequency content that computing is set is to calculate Respiration Rate, so can bodies different for frequency is dynamic and breathing strictly distinguish accurately, more really can ensure whether safety monitors.
And safety whether information is made up of the dynamic number of body and Respiration Rate, whether pattern monitors by the dynamic number of body and Respiration Rate safety, thus not only can the action of guarder, whether extremely can also monitor the health status of this person.
Further, noise contribution relatively can be prevented by error detection by threshold value.
Following structure can also be adopted, the body possessing the change in value preset described in making moves threshold value configuration part, described threshold value comparison circuit moves by described body the described microwave time rate of change data of numerical value that threshold value configuration part changes move signal to export as effective body using exceeding, possesses the respiration threshold configuration part that can set any number, described fundamental current detection circuit according among the frequency distribution data exported from fft circuit, intensity exceeds the frequency distribution data of the described arbitrary numerical value set by respiration threshold configuration part, exports first-harmonic data.
According to such structure, by adjusting the threshold value being moved threshold value configuration part and the setting of respiration threshold configuration part by body, thus the signal being moved and breathe generation by body that other persons under inspection beyond the object originally monitored from each sensor unit can be detected is removed as noise.
Thus, can prevent and even suppress the safety of person under inspection whether the accuracy of detection of state occur reducing.
Can also adopt following structure, body moves threshold value configuration part and the described respiration threshold configuration part condition according to the microwave Doppler sensor be set up to set different threshold values.
According to such structure, due to can according to the condition of the microwave Doppler sensor be set up (such as, its the open degree in the space that environment and setting place are set, the density level etc. of person under inspection) set threshold value, thus, can be suitable for the sensitivity of its condition to obtain data.
That is, make compared with microwave time rate of change and the predetermined numerical value (threshold value) that contrasts changes by utilizing body to move threshold value configuration part, thus can carry out moving the adjustment counting relevant detection sensitivity with body.
Thus, by reducing detection sensitivity (increasing threshold value or expanding the situation of fabric width of threshold value), reduce thus utilize safety whether monitoring arrangement monitor from the noise (echo from the acceptor beyond person under inspection) produced as the echo (acceptor beyond person under inspection is positioned at the situation etc. near person under inspection) beyond the person under inspection of monitored object; By improving detection sensitivity (reducing the situation of fabric width of threshold value or constriction threshold value), can prevent the detection when distant from microwave receiver to person under inspection from omitting thus.
In addition, by respiration threshold configuration part, the arbitrary numerical value comparing with the numerical value of the intensity of first-harmonic data and contrast can be set, thus the adjustment of the detection sensitivity of the frequency distribution data for detecting first-harmonic data can be carried out.
Thus, by reducing detection sensitivity (increasing the situation of threshold value), reduce thus utilize safety whether monitoring arrangement monitor from the noise (echo from the acceptor beyond person under inspection) produced as the echo (acceptor beyond person under inspection is positioned at the situation etc. of the vicinity of person under inspection) beyond the person under inspection of monitored object; By improving detection sensitivity (reducing the situation of threshold value), can prevent the detection when distant from microwave receiver to person under inspection from omitting thus.
Safety whether mode decision portion judges that the specified time limit of safety whether rank can be one day.
According to such structure, with regard to safety rank, it is that the accumulation of whether counting by safety specifies, but, in general by judging by accumulation one day is so much, can obtain suitable reply.
Following structure can also be adopted, whether judge based on multiple safety safety whether pattern is carried out, then being taken as when meeting any one in following (A)-(E) and representing uneasy judgement, being then taken as the judgement representing safety when not meeting any one
(A) body moves aberrant continuation more than the 1st time
(B) adnormal respiration continued for the 2nd time
(C) have body to move to continue more than the 3rd time
(D) play dynamic without body from the state of moving and breathing normal or aberrant continuation the 4th time more than without body and do not detect that breathing continued for the 5th time
(E) have body dynamic after, within the 6th time to the 7th time, dynamic and do not detect that breathing continues always without body.
According to such structure, then can judge safety whether pattern simply, the general action model (action model of normal health person: the pattern representing " safety " during safety is whether) of person under inspection, or abnormal action model (representing the pattern of " not the safety " during safety whether).Following content can be adopted: by day with the band length of one's sleep, the time length of the the 1 to the 5 and the 1 to the 7 is each inconsistent.
Generally speaking, body under the band length of one's sleep (person under inspection is sleep state) is dynamic and breathe, that the interval moving according to the body be different under daytime and non-sleep time-bands (person under inspection is awake state) and breathe carries out, thus, by being with the length of one's sleep like this by day, by the 1st time to the 5th time and be set to inconsistent to the time span of the 7th time, by day with the band length of one's sleep, the precision of the safety of person under inspection whether mode data all can be made to be improved.
Can also adopt following structure, whether device for informing possesses the communication unit of output notification data and the communication monitoring portion of the communication function of supervision communication unit to safety.
By adopting such structure, because can monitor that most important communication function is whether normal, so the safety whether monitoring arrangement being rich in reliability can be formed.
By the present invention, because body can be used to move number and Respiration Rate to carry out safety whether supervision, so high accuracy safety whether supervision can be carried out.In addition, for the people of separately life and solitary old people, only with body dynamic detect not easily detect, body is dynamic occur hardly time, also can detect the change of people's appearance state.And, a kind of safety detecting abnormal, the less generation of high detection accuracy, misidentification of people's health status whether monitoring arrangement can also be provided.

(body moves the action specification of device for detecting respiratory: Fig. 2-Fig. 4)
Next the action of Fig. 2-Fig. 4 to the safety of the present invention whether embodiment 1 of monitoring arrangement is utilized to be described.First, the action that body moves device for detecting respiratory 5 is described.Fig. 3 and Fig. 4 is the oscillogram that the body shown in key diagram 2 moves the action of device for detecting respiratory 5, and horizontal axis representing time, the longitudinal axis represents amplitude.
First the action that body moves count section 51 is described.Fig. 3 (a) display is input to the microwave time rate of change data Dd that body moves the Digital Microwave data Md in the time differential circuit 511 of device for detecting respiratory 5 and carried out time diffusion process by time differential circuit 511.Fig. 3 (b) shows effective body and moves signal Cd and body and move the relation that body that counting circuit 513 exports moves several Td.
As shown in Fig. 3 (a), if the Digital Microwave data Md of input is temporally carrying out differential through time differential circuit 511, then owing to there is the time rate of change of signal, so microwave time rate of change data Dd forms the waveform making a certain amplitude range increase and decrease centered by 0 (zero).
Microwave time rate of change data Dd is compared with the numerical value preset according to threshold value comparison circuit 512, namely compared with two threshold values represented by "+threshold value ", "-threshold value " shown in Fig. 3 (a), and the microwave time rate of change data Dd larger than "+the threshold value ", "-threshold value " that preset moves signal Cd as effective body and exported by threshold value comparison circuit 512.In addition, described "+threshold value " and "-threshold value " can experimentally etc. set in advance.
Body moves counting circuit 513 moves the moving body of signal Cd and the 2nd timing signal T2 output unit time number of times and body dynamic number Td according to effective body.The pulse signal of the 2nd timing signal T2 to be the pulse period be 5-30 second, the such as time in units of 30 seconds.In Fig. 3 (b) illustrated embodiment, the unit interval is the dynamic number of body of described 30 seconds (the 2nd timing signal T2) is " 9 ".
Next respiration detection portion 52 is described.Fig. 4 (a) and Fig. 4 (b) shows in the mode of lay out in parallel Digital Microwave data Md and frequency distribution data F s, and this frequency distribution data Fs is exported by fft circuit 521 based on Digital Microwave data Md.In the figure of display Digital Microwave data Md, take time as transverse axis, with the amplitude of signal for the longitudinal axis represents; In the figure of display frequency distributed data Fs, take frequency as transverse axis, with the intensity of signal for the longitudinal axis represents.And Fig. 4 (a) represents the situation that person under inspection 10 does not have body dynamic, and Fig. 4 (b) indicates the situation that body is dynamic.
Fft circuit 521 based on the 2nd timing signal T2 at stipulated time savings Digital Microwave data Md carry out FFT process.Described FFT process carries out fast fourier transform process to input signal.That is, the Digital Microwave data Md of savings is carried out Fourier transform, after resolving into each signal component, the process shown in frequency spectrum is carried out to each composition, output to fundamental current detection circuit 522 as frequency distribution data Fs.In the stipulated time, the 2nd timing signal T2 of savings Digital Microwave data Md is such as 30 seconds in the case.
Respiratory waveform comprises everyone intrinsic harmonic wave, instead of simple sine wave, and, if also move containing body, then can not detect each waveform in fact.Therefore can detect in the following way, that is: collect actual waveform at Time constant like this and carry out FFT process, the fourier spectrometer resolving into each frequency detects.
Fundamental current detection circuit 522 exports first-harmonic data Rf according to the frequency distribution data Fs of input, but, as shown in Figure 4, select the frequency distribution of in frequency distribution data Fs, relevant to breathing prescribed limit, the frequency content wherein comprising maximum intensity (peak value) p is outputted to respiratory count circuit 523 as first-harmonic data Rf.
That is, fundamental current detection circuit 522 is by the frequency distribution being shown as the scope of interval R among frequency distribution data Fs as shown in Fig. 4 (a) and Fig. 4 (b), samples as the composition relevant to breathing.Determine that two frequency R1 and R2 of this interval R are such as the intervals of 0.2Hz to 0.5Hz.In addition, frequency R1's and R2 is selected, carry out experiment and waits and selectedly can catch and breathe relevant frequency distribution scope.
Because biological respinse is with normal distribution, so read composition successively from frequency R1 side in interval R.And, if select peak-peak p, then can predict that it is exactly the first-harmonic breathed.But, be preferably as follows mode: be not now only select single component and peak value the highest as p, if select continuous 2 times in rising trend, and meet for identify noise and condition more than specific threshold as p, then can obtain the first-harmonic data Rf of higher accuracy.
Fig. 4 (b) shows the dynamic situation of body, in its waveform, except comprising and breathing except relevant frequency distribution, also comprises and moves relevant frequency distribution to body.Frequency distribution as interval T indication range is moved relevant composition as to body.Determining two frequency R3 and R4 of described interval T, such as, is the interval of 0.5Hz to 5.0Hz.Described interval T moves relevant frequency distribution to body, so remove from first-harmonic data Rf.In addition, test etc., frequency R3 and R4 selectes to capture and moves relevant frequency distribution scope to body.Importantly, if interval T is more best than the large words of frequency range of breathing.In this embodiment, if determine, the words that the frequency R3 of interval T is higher than frequency R2 are best.Clear and definite periodicity is not had, so the frequency distribution data Fs after FFT process can not occur as clear and definite frequency content because body moves.Therefore, in the present invention, the frequency range moved by regulation body, as interval T, can be got rid of and breathe different compositions.
Respiratory count circuit 523 calculates Respiration Rate Rr according to the first-harmonic data Rf of input.That is, by first-harmonic data Rf is expanded 60 times, the unit of account time is namely as the Respiration Rate Rr of frequency of respiration per minute.
Whether the action specification 1 of mode decision portion (safety)
Next, judge that the action in safety whether safety whether mode decision portion 6 is described to moving according to body and breathing.First, the judgment standard that body moves several Td and Respiration Rate Rr can use example shown below.
Td is as follows for body dynamic number.
Body dynamic number Td≤10: " moving without body "
Body dynamic number Td > 10: " having body to move "
Body dynamic number Td > 500: " body is dynamic abnormal "
Respiration Rate Rr is as follows.
First-harmonic data Rf is detected: " breathing normal " at interval R
First-harmonic data Rf is detected: " adnormal respiration " at more than frequency R2
First-harmonic data Rf do not detected: " breathing not detected "
In addition, move according to these bodies the state that number and Respiration Rate to move body and breathe to distinguish, body can be utilized to move device for detecting respiratory 5 carry out, in this case, safety whether mode decision portion 6 is carried out following safety based on the differentiation result that body moves number and Respiration Rate and whether is judged.
Whether mode decision portion 6 is in order to detect whether safety for safety, and whether multiple conditions, the i.e. safety shown in below use whether pattern judge the safety of person under inspection, makes safety whether mode data As.Safety whether pattern shows 5 conditions of A-E.In addition, will be judged to be that the N/R state of person under inspection is called " safety judgement "; To be judged to be that person under inspection has abnormal state to be called " not safety judgement ".
(Mode A)
If " body is dynamic abnormal " continues during time t1, is " not safety judgement ".Time t1, such as, daytime is 10 minutes, and the band length of one's sleep (night) is 5 minutes.
About above-mentioned Mode A, usually the situation continuing the strenuous exercise carrying out Time constant in indoor is waited to be judged as exception old people.Described time t1 is have selected in order to detect this type of situation.
(Mode B)
If " adnormal respiration " continues during time t 2, be considered as " not safety judgement ".Time t2 is such as 10 minutes by day, and being with in the length of one's sleep is 3 minutes.
About described Mode B, usually the situation continuing the quick breathing carrying out Time constant in indoor is waited to be judged as exception old people.Described time t2 is have selected in order to detect this type of situation.
(pattern C)
If " having body to move " continues during time t3, be considered as " not safety judgement ".Time t3 is such as 60 minutes by day, and being with in the length of one's sleep is 10 minutes.
About described pattern C, usually the situation continuing the body movement carrying out Time constant in indoor is waited to be judged as exception old people.Described time t3 is have selected in order to detect this type of situation.
(pattern D)
" dynamic without body " and " breathing normal or abnormal " continues after the state of time more than t4 (lower than time t2), if " moving without body " and " breathing not detected " continue during time t5, is then considered as " not safety judgement ".Time t4 is such as 5 minutes by day, and being with in the length of one's sleep is 3 minutes.Time t5 is such as 5 minutes by day, and being with in the length of one's sleep is 3 minutes.
About described pattern D, if person under inspection goes out, owing to moving to outdoor so certainly with temporary " having body to move " or " body is dynamic abnormal " before becoming " not detecting breathing ".Exception is judged as to the situation losing suddenly breathing from " moving without body " state.Described time t4 and time t5 is have selected in order to detect this type of situation.
(pattern E)
After " having body to move ", within time t6, if " moving without body " and " breathing not detected " continue during time t7, be considered as " not safety judgement ".Time t6 is such as 2 minutes by day, and being with in the length of one's sleep is 2 minutes.Time t7 is such as 60 minutes by day, and being with in the length of one's sleep is 20 minutes.
About above-mentioned pattern E, after being judged to be that person under inspection is " having body to move " or " body is dynamic abnormal ", more than Time constant, the state that body moves and breathes not detected, can think outdoor of going out yet.All do not recover if move at Time constant endosome or breathe, be then judged as exception.
Detected by the frequency content of carrying out Fourier transform and breathe.Body is dynamic to be detected by differentiated waveform.Thus, breathe dynamic with body compared with, due to affected by noise, breathe hardly and do not occur to detect mistake.Therefore, that moves about body and breathe does not detect continuously, and body is dynamic preferential, and under body moves continuous nonevent state, independent one-time detection is considered as detecting mistake to the case of breathing, and thinks invalid.
Whether pattern is to judging that " the not safety judgement " of person under inspection as abnormality is defined for above-mentioned safety, and certainly, if do not meet any one words, person under inspection is without exception, is " safety judgement ".
Safety whether mode decision portion 6 uses above-mentioned safety whether Mode A-E, carries out safety respectively whether judge by set timing.Such as every 30 seconds.This timing with for jointly using the 3rd timing signal T3 shown in Fig. 2 " daytime " and " length of one's sleep is with (night) " in described safety whether pattern.Described 3rd timing signal T 3, as described in illustrating, has the information such as date and time.
Be provided with not shown storage part in the inside in safety whether mode decision portion 6, whether Mode A-E is stored in this storage part the safety of above-mentioned explanation.Described safety whether pattern, except the embodiment illustrated, can also select various judgment standard according to the feature of person under inspection and action model.In addition, other several safeties whether pattern can also be prepared in advance, according to circumstances use respectively.
Whether the action specification 2: Fig. 5 of mode decision portion (safety)
Next, Fig. 5 other action to safety whether mode decision portion 6 is utilized to be described.Described action is such action, that is, due to safety, whether the emergency of pattern, life and death importance degree are different, whether count, and whether the safety of 1 day is counted add up to whether rank exports as safety so preset the safety corresponding with each pattern.
Fig. 5 (a) by multiple safety whether pattern and counting of each pattern represent in the table, the safety of use whether pattern is the embodiment using the safety that illustrated whether Mode A-E.In addition, Fig. 5 (b) is by the safety whether rank of display emergency, and the accumulative total whether safety of 1 day counts and gerentocratic corresponding expression are corresponding thereto in the table.
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 gives safety whether counts " 3 ", to safety, whether Mode B gives safety whether counts " 2 ", to safety, whether pattern C gives safety whether counts " 1 ", to safety, whether pattern D gives safety whether counts " 10 ", and to safety, whether pattern E gives safety whether counts " 5 ".
Whether safety is counted and to be determined according to life and death importance degree.Such as, whether the safety of pattern C counts as " 1 ", and Mode A is " 3 ".Pattern C is described above, although " having body to move ", the words continued among time t3 are then " not safety judgement ".The embodiment of time t3, daytime is 60 minutes, and the length of one's sleep, band was 10 minutes.If for daytime, the state of " having body to move " at least detected at 60 minutes.On the other hand, Mode A is " having body to move ", it would be better to say that it is violent " body is dynamic abnormal ", but, be the situation that (such as, daytime is 10 minutes, and the length of one's sleep, band was 5 minutes) continues in time t1.So due to compared with Mode A, pattern C can not be the state of violent body, so whether face this point of life and death from person under inspection, can think that the probability of person under inspection's existence (namely not facing death) is high in pattern C.According to described judgement, to each safety, whether pattern carries out the such importance degree judgement of life and death importance degree.
For each safety, whether pattern presets safety whether counts, and the safety determined according to the aggregate-value whether safety of 1 day counts whether rank, such as, setting " low ", " in ", " height " 3 stages.If the aggregate-value whether safety counts is the words of " 1-3 ", whether rank is " low " to safety, if the aggregate-value whether safety counts is the words of " 4-9 ", safety whether rank be " in ", if the aggregate-value whether safety counts is the words of more than " 10 ", whether rank is " height " to safety.
Due to safety, whether rank is the aggregate-value whether safety counts, so with Fig. 5 (b) illustrated embodiment, whether the safety of pattern C counts is 1, if the words of 1 time only occurred at 1 day described pattern C, then as shown in Fig. 5 (b), whether rank is " low " to safety.But, although not diagram, if described pattern C occurred 4 times at 1 day, safety whether rank be then " in ", the words that generation in 1 day is 10 times are then " height ".
That is, struggle with misery compared with such " body is dynamic abnormal ", constantly such " adnormal respiration " of cough may be slight exception, but, if should " adnormal respiration " repeat at 1 day to occur for several times, then may be serious exception instead of mile abnormality.Now whether counted and safety whether rank by setting safety, the exception of person under inspection just becomes and easily distinguishes.
In addition, also can according to safety whether rank determination attribute, the attribute of safety whether rank " low " is " confirming according to image information ", safety whether rank " in " be " by conversing, direct session confirms ", whether rank " height " is " access confirmation " to safety.Attribute " access confirmation " preferably accesses to confirm safety whether situation at once, and attribute " confirms according to image information ", " by conversing, direct session confirms " can be in the situation not having such emergency.These attributes are incorporated into safety whether in mode data As.
About safety described later whether device for informing 7, if the content of safety whether mode data As is judged to be that person under inspection has abnormal " not safety judgement ", then the content of safety whether mode data As is sent as notification data N by communication unit 73, now, the information that the manager of information also can obtain safety whether rank and attribute if receive, whether be suitable for going person under inspection to access at once at one's side, still only use communicator 82 " whether to have exception " etc. to person under inspection's inquiry can wait, the many increases of material of such a judgement some, be then more convenient for judge.
Above, just multiple safety whether pattern number and give each safety whether pattern give safety and whether to count and the number of safety whether rank is illustrated, but to be not limited thereto, can to set according to person under inspection and surrounding.
(action specification of safety whether device for informing: Fig. 2-Fig. 4)
Next, the action of safety whether device for informing 7 is described.From the safety whether safety that exports of mode decision portion 6 whether mode data As, once be stored in storage part 71, then as safety, whether pattern storage data Sd reads from storage part 71, and is output to circular judging part 72.Circular judging part 72 judges whether whether pattern storage data Sd is the rank needing to circulate a notice of for the safety that inputs.
Lift an example, if safety whether the content of mode data As be judged to be that person under inspection does not have abnormal " safety judgements ", be then judged as it not being the rank needing to circulate a notice of.In addition, if the content of safety whether mode data As is judged to be that person under inspection has abnormal " not safety judgement ", then the content of safety whether mode data As is added to circular index signal Ed, and exports circular index signal Ed.
Circular index signal Ed sends to outside as notification data N by communication unit 73.As communication unit 73, digital modulator can be taked and be connected to the combination of electric wire control device of regular phone line, also can adopt analog or digital radio transmitters.
(outward appearance illustrates: Fig. 7) following, uses Fig. 7 that the outward appearance of safety whether monitoring arrangement 1 is described.81 is display in the figure 7, and 82 is communicators, and they are the important documents forming device for informing 8.83 and 84 is console switchs.As shown in Figure 7, safety whether monitoring arrangement 1 has the outward appearance close to table photograph stand, is accommodated with microwave Doppler sensor 3 on top, and front surface is provided with the display 81 of device for informing 8, communicator 82 and console switch 83,84.
Display 81 can use liquid crystal display.As already explained, according to the content from the safety whether safety that exports of mode decision portion 6 whether mode data As, " having exception? " can be shown Deng word.
Communicator 82 can be carried out the ceramic audio device of inquiry by the sound sent to person under inspection as " whether having exception " or dynamic speaker is formed.
In addition, safety whether monitoring arrangement 1 be also mounted with can receive to answer etc. from person under inspection while the communicator of call, 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 operating the displaying contents of display 81 and volume, or replys the inquiry from communicator 82, can use the switch of button-type.Such as, for the inquiry as " whether having exception " from display 81 or communicator 82, when person under inspection is without any problem, by operating etc. console switch 83 or console switch 84 in official hour, the state of person under inspection is input to safety whether monitoring arrangement 1.
(explanation of the motion flow of embodiment 1: Fig. 2, Fig. 6)
Below, Fig. 2 and Fig. 6 is used to describe the motion flow of safety whether monitoring arrangement 1 in detail.Fig. 6 is the motion flow that the safety whether action of monitoring arrangement 1 is described.Below be described in detail.
S1 is the program reading signal.By microwave Doppler frequency shift signal Ma according to resolution 10bit, convert Digital Microwave data Md to the sample rate of approximately every 10msec.(S1)
S2 exports according to Digital Microwave data Md the macroprogram that body moves several Td.Below be described in detail.
Digital Microwave data Md process sampled is be expressed as V (n) n-th time according to sampling number of times, and time diffusion carries out as described below.
Δ V=V (n)-V (n-1) calculates receding diffierence (Δ V) with the numerical value of a sampling above.(S21)
Move aggregate-value by following two conditions to body to count.(S22) Δ V > 0.05V (being equivalent to+threshold value), Δ V≤0.05V (being equivalent to-threshold value), this numerical value of described 0.05V is threshold value, and this is an example.Owing to need not consider to be provided with the environment noise of the safety whether environment of device, and determine by experiment etc.
The Wave data of 30 seconds these parts is stored in array V (n); In addition, the body dynamic number Td in 30 seconds is exported.(S23)
Judge according to the dynamic number of the bodies of 30 seconds.(S24) if body dynamic number > 10, then judge it is " having body to move "; If the dynamic number≤10 of body, then judge it is " moving without body ".If body dynamic number > 500, judge it is " body is dynamic abnormal ".
S3 is the mastery routine exporting Respiration Rate Rr.FFT conversion is carried out to the Digital Microwave data Md between 30 seconds.Carry out breathing according to the first-harmonic data Rf extracted out to judge.(S3) in interval R (at more than 0.2Hz, lower than 0.5Hz), detect first-harmonic data Rf, be then judged to be " breathing normal ".First-harmonic data Rf detected at more than frequency R2 (0.5Hz), be then judged to be " adnormal respiration ".If first-harmonic data Rf do not detected, be then judged to be " breathing not detected ".
S4 judges safety whether mastery routine.Safety whether mode data As is exported according to the dynamic number of the body during 30 seconds Td and Respiration Rate Rr.In addition, according to the content of safety whether mode data As, proposed as inquiries such as " what's the matter " to person under inspection 10 by device for informing 8.(S4)
S5 is stored in the program in the data file of storage part 71.Result between 30 seconds and date and time are together kept in the data file of 24 hours forms.In addition, except date, time, the dynamic number of body, body dynamic number cumulative number, Respiration Rate etc., also respiratory frequency Distribution Value, respiratory wave spectrum is stored as required.(S5)
S6 is the program carrying out circulating a notice of and showing.According to safety whether pattern storage data Sd content or as required with reference to the content of safety in the past whether pattern storage data Sd, send notification data N in emergency situations.(S6)
By above step, the shortcoming of existing mode can being overcome, such as, when there is no that TV is watched in more dynamic such sleeping for a long time etc., being difficult to detect the exception that person under inspection produces or detect the exception of health status.
(embodiment 2)
(structure of safety whether monitoring arrangement illustrates: Figure 10)
Next, utilize Figure 10 so that the embodiment 2 of safety whether monitoring arrangement to be described.In the safety of the safety relevant with embodiment 2 whether monitoring arrangement 100 whether among device for informing 7, the function be also added with for monitoring communication unit 73 is normal communication monitoring portion 73a, thus whether safety is monitored, and Reliability of Microprocessor is higher.
Figure 10 be display safety whether monitoring arrangement 100 the functional block diagram of structure, only indicate safety whether device for informing 7a and the relevant device for informing 8 as the important document being different from embodiment 1.
The communication monitoring portion 73a of safety whether device for informing 7a, to communication unit 73 output function maintenance signal Hk, differentiates that whether the function of communication unit 73 is normal.Specifically, function overhaul signal Hk is the test program making communication unit 73 analog operation.Although this test program is diagram not, storage part is set and is stored in communication monitoring portion 73a.
If the abnormal words of the function of communication unit 73, then caution signals A1 is outputted to device for informing 8 by communication monitoring portion 73a.Device for informing 8 shows the caution signals A1 inputted from communication monitoring portion 73a by display 81, and to be given a warning sound by communicator 82, 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 the explanation repeated is omitted.
(effect of embodiment 2 illustrates)
The most important function of safety whether monitoring arrangement monitors safety whether function and information is sent to outside function.For the people that solitary old people etc. lives separately, be the important document being equivalent to unique safety belt with outside contact.Even if safety whether monitoring arrangement correctly can monitor the state of person under inspection, but, if whether device for informing can not works fine, without any meaning for its situation being delivered to outside safety.For this reason, if carried out the supervision of communication function by communication monitoring portion, can say that the reliability of safety whether monitoring arrangement improves further.
The embodiment of above-mentioned explanation is not limited thereto, if meet purport of the present invention, much less can change arbitrarily.
(embodiment 3)
(being divided into the structure of sensor unit and server)
Whether monitoring arrangement 1,100 can form following structure to the safety of the various embodiments described above: as shown in figure 12, microwave Doppler sensor 3, signal processing part 4, timing unit 9 and body move device for detecting respiratory 5 and form as integral sensor unit 300, safety whether mode decision portion 6, safety whether device for informing 7 and device for informing 8 are provided in and separate with sensor unit 300 and in the server 400 had a style of one's own, sensor unit 300 and server 400 link by communication line 600.
And sensor unit 300 is arranged on particular space, this particular space is such as become the room etc. relying on this safety whether monitoring arrangement 1,100 person under inspection 10 place usually of carrying out the object monitored.
On the other hand, server 400 is arranged on the place (place (being such as guard company and hospital etc.) to the safety manager whether monitoring arrangement 1,100 manages often treats) of the setting place being different from sensor unit 300.
Communication line 600 can be both Wireline, may also be the radiolinks such as WiFi.
When communication line 600 adopts radiolink to form, as shown in figure 13, this communication line 600 possesses: wireless transmission part 610, the body from sensor unit 300 is moved the signal that device for detecting respiratory 5 exports and sends as wireless signal; Wireless receiving section 620, receives the wireless signal sent from wireless transmission part 610, converts wire signal to and export; The circuit such as the Internet and LAN 640, makes the signal circulation exported from wireless receiving section 620; Data reception portion 630, reads in the signal of flowing in circuit 640.
Herein, wireless transmission part 610 is wholely set in sensor unit 300, and be transfused to the output data (body dynamic number Td, Respiration Rate Rr) and the output data (the 3rd timing signal T3) from timing unit 9 of carrying out autologous dynamic device for detecting respiratory 5, convert these data to wireless signal and send.
On the other hand, data reception portion 630 is arranged in server 400, and the data inputted from circuit 640 (body dynamic number Td, Respiration Rate Rr, the 3rd timing signal T3) is input to safety whether in mode decision portion 6.
Body dynamic number Td, the Respiration Rate Rr of device for detecting respiratory 5 output is moved from the body shown in embodiment 1, it is the initial data that the body detected within the unit interval moves number, Respiration Rate, but, below in an example, body dynamic number Td becomes the data being divided into " body is dynamic abnormal ", " having body to move ", " moving without body " 3 kinds of situations (point rank); Respiration Rate Rr becomes the data being divided into " adnormal respiration ", " breathing normal ", " breathing not detected " 3 kinds of situations (point rank).
In addition, above-mentioned 3 kinds of divisions that body moves several Td are identical with the division in embodiment 1, are defined as:
During dynamic number Td≤10 (less than 10) of body " dynamic without body "
" body is had to move " when body moves and counts Td > 10 (more than 10)
During dynamic number Td > 500 (more than 500) of body " body is dynamic abnormal ".
Similarly, above-mentioned 3 kinds of Respiration Rate Rr divide identical with division shown in embodiment 1, are defined as:
" breathe normal " when interval R detects first-harmonic data Rf
When more than frequency R2 detects first-harmonic data Rf " adnormal respiration "
When first-harmonic data Rf not detected " breathing not detected ".
In addition, wireless receiving section 620 is arranged in the scope of the distance that can receive the wireless signal sent from wireless transmission part 610.
If utilize safety in the embodiment of above-mentioned formation whether monitoring arrangement 1,100, except there is the effect of the above embodiments 1,2, sensor unit 300 can also be utilized to carry out moving as detected the body of person under inspection 10, breathe the smaller process of processing load, utilize and carry out the larger process of other processing load with the server 400 had a style of one's own that sensor unit 300 separates, thus, sensor unit 300 can be formed with smaller size according to the needs of processing load.
(there is the structure of multiple sensor unit)
And, in order to the parallel or multiple data of batch process of server 400 can be utilized, and multiple sensor unit 300,300...... etc. are combined in single server 400, form safety whether monitoring arrangement 1,100 thus.
Namely, as shown in figure 14, multidigit patient is had in a ward in hospital, each patient is considered as person under inspection 10 (the person under inspection 10A of bed A respectively, the person under inspection 10B of bed B), sensor unit 300A, 300B with respectively with person under inspection 10A, the mode that 10B is corresponding is arranged (the corresponding person under inspection 10A of sensor unit 300A, the corresponding person under inspection 10B of sensor unit 300B), a wireless receiving section 620 is only equipped in described ward, LAN in ward is taken as circuit 640, possesses the single server 400 be arranged in hospital, thus by said structure to form safety of the present invention whether monitoring arrangement.
In this case, due to the safety in server 400, whether mode decision portion 6 needs to differentiate that the data inputted from data reception portion 630 are at two person under inspection 10A, person under inspection 10A is belonged in 10B, still the data of person under inspection 10B are belonged to, so, make respectively with person under inspection 10A, each sensor unit 300A that person under inspection 10B is corresponding, 300B, respectively with for such as ID (identification) number by sensor unit 300 particular procedure in its each wireless transmission part 610, data (the body dynamic number Td that each wireless transmission part 610 sends, Respiration Rate Rr, 3rd timing signal T3) be added described id number, such as be sent out as header.
On the other hand, object registration information storage part 800 is equipped with in server 400, this object registration information storage part 800 is by the information (such as above-mentioned id number) of each sensor unit 300A, 300B particular procedure corresponding to person under inspection 10A, person under inspection 10B, corresponding relation is set up with person under inspection 10A, person under inspection 10B, stored as object registration information, further, the object registration information be stored in object registration information storage part 800 is input to safety whether in mode decision portion 6.
And, if data are input to safety whether mode decision portion 6 respectively from each sensor unit 300A, 300B, then whether mode decision portion 6 reads the id number be added as header being input into data to safety, thus, may be used for judging as with the data by corresponding person under inspection 10A, the 10B of the id number of object registration information particular procedure.
In addition, sensor unit 300A, 300B is respectively with a people person under inspection 10A, 10B is as monitored object, but, picture as shown in figure 14 have multidigit person under inspection 10A, 10B is until in a ward time, at the person under inspection 10A of monitored object, the vicinity of 10B also has other person under inspection 10A, when 10B, each sensor unit 300A, 300B, except the person under inspection 10A that may detect as original monitored object, the microwave reflection that 10B sends is (by person under inspection 10A, the microwave M that 10B reflects) beyond, also likely detect it is not natively other person under inspection 10B of monitored object, the microwave reflection that 10A sends.
And, once also detect it is not natively the microwave reflection that other person under inspection 10B, 10A of monitored object send, person under inspection 10A, 10B whether safety as original monitored object probably correctly can not be detected.
For this reason in the safety of each embodiment whether in monitoring arrangement 1 grade, all can take as under type: as shown in figure 15, in each sensor unit 300, be equipped with body move threshold value configuration part 531, this body moves the numerical value preset, i.e. threshold value that threshold value configuration part 531 makes expression in Fig. 3 (a) (in+scope between threshold value and-threshold value) and changes, in addition, threshold value comparison circuit 512 moves signal as effective body export exceeding the microwave time rate of change data moving numerical value that threshold value configuration part 531 changes (in+scope between threshold value and-threshold value) by body; Outfit can set the respiration threshold configuration part 532 of the threshold value of any number shown in Fig. 4 (c), in addition, fundamental current detection circuit 522 according among the frequency distribution data Fs exported from fft circuit 521, intensity exceeds the frequency distribution data F s of the threshold value set by respiration threshold configuration part 532, exports first-harmonic data Rf.
Herein, moving by body the threshold value that threshold value configuration part 531 sets, being removed as noise and the numerical value determined based on experiment fully in advance etc. to the body by this not being the person under inspection of monitored object be moved the signal caused.
That is, move by body the threshold value that threshold value configuration part 531 sets, such as, can set according to the condition of the microwave Doppler sensor be set up (specifically, the room-size of setting, the number, interval etc. of sensor unit that arrange in a room).
In addition, the threshold value set by respiration threshold configuration part 532 is the numerical value determined based on experiment fully in advance etc. to remove as noise by the signal caused by the breathing not originally being the person under inspection of monitored object.
If utilize such structure, utilize body to move threshold value configuration part 531 and make to change with the predetermined numerical value (threshold value) of microwave time rate of change data comparison and contrast, thus can carry out relating to the adjustment that body moves the detection sensitivity of counting; Utilize respiration threshold configuration part 532 to make to change with the arbitrary numerical value (threshold value) of the numerical value comparison and contrast of the intensity of first-harmonic data, thus the adjustment of the detection sensitivity of the frequency distribution data F s for detecting first-harmonic data Rf can be carried out.
Thus, sensor unit 300A, except detecting the microwave reflection from the person under inspection 10A as original monitored object, can also suppress the detection to carrying out from the microwave reflection not originally being the person under inspection 10B of monitored object; Sensor unit 300B, except detecting the microwave reflection from the person under inspection 10B as original monitored object, can also suppress the detection to carrying out from the microwave reflection not originally being the person under inspection 10A of monitored object.
Thus, the reduction of the safety that can prevent and even suppress each person under inspection 10A, 10B whether accuracy of detection of state.
In addition, body moves the adjustment of adjustment and respiration threshold configuration part 532 pairs of threshold values of the 531 pairs of threshold values in threshold value configuration part, self-evidently also to be applicable in the embodiment shown in Fig. 1,2, and and to be not only and just can to carry out in the structure being partitioned into sensor unit 300 and server 400.
In addition, body moves the adjustment of adjustment and respiration threshold configuration part 532 pairs of threshold values of the 531 pairs of threshold values in threshold value configuration part, the room-size etc. can stayed according to the person under inspection 10 of the monitored object as sensor unit 300 is carried out, and is not that to be only limitted to exist the situation of several person under inspection in a ward just passable.Such as, as the threshold value moved threshold value configuration part 531 by body and set, when only having a person under inspection 10 to exist in the room that area is larger and intend to examine scope at about 5m of ranging sensor element 300 distance, "+threshold value " can be set to+0.1 (V), "-threshold value " be set to about-0.1 (V).
On the other hand, as mentioned above between one, there is multidigit person under inspection 10A, 10B in ward and intends to examine the scope of ranging sensor element 300 distance within 1m, "+threshold value " can be set to+1.0 (V), "-threshold value " is set to-1.0 (V) left and right.Be 6 tatamis (about 10m in room-size
2) apartment in, only there is a person under inspection 10 and intend inspection ranging sensor element 300 distance (do not intend to detect next door, apartment other people when) when the scope of about 2m, "+threshold value " can be set to value between+1.0 (V) and+0.1 (V), "-threshold value " be set to value between-1.0 (V) and-0.1 (V).
In addition, as the threshold value set by respiration threshold configuration part 532, when only having a person under inspection 10 to exist in very wide room and intend to examine the scope of ranging sensor element 300 apart from about 5m, " threshold value " can be set to about 0.5.
On the other hand, there is multidigit person under inspection 10A, 10B in ward and intends to examine scope within 1m of ranging sensor element 300 distance between one as mentioned above, " threshold value " can be set to about 1.0.When only having a person under inspection 10 to intend to examine scope at about 2m of ranging sensor element 300 distance in the apartment that room-size is 6 tatamis (do not intend to detect next door, apartment other people), threshold value can be set to the value between 1.0 and 0.5.
(embodiment 4)
The safety of above-described embodiment 3 whether monitoring arrangement 1 etc. is the situation that can corresponding have the person under inspection 10 of more than 2 or 2 to exist in a space (ward), but, Figure 16 be in contrast correspond to such as only have a person under inspection 10 to exist but more than using between the embodiment of situation (Figure 17) in room.Namely, in general supposition is the situation with a personal lifestyle in only the house in above room between two or condominium, in this case, person under inspection 10 as monitored object is one, but, as shown in figure 17, multiple sensor unit 300A, 300B, 300C, 300D with correspond respectively to room, bedroom, bathroom, each room of toilet mode arrange.
Like this, be provided with the situation of sensor unit 300 respectively among each room as multiple place different from each other under, due to person under inspection 10 the specific time only stay in room, bedroom, bathroom, these rooms of toilet wherein between one, so, if the safety of server 400 whether mode decision portion 6 is only carried out safety according to the signal being arranged on the sensor unit 300 do not stayed in room and whether is judged, then probably can the result of output error.
For this reason, the safety of the embodiment is in figure 16 whether in monitoring arrangement 1 grade, data merging portion 700 is equipped with in server 400, this data merging portion 700 needs the output of the sensor unit 300A-300D of combination to combine by corresponding to person under inspection 10, and as safety, whether information exports.
With regard to the sensor unit 300A-300D that needs are grouped together in data merging portion 700, in server 400, in advance by the information (such as id number) of the sensor unit 300A-300D of 4 corresponding persons under inspection 10 through particular procedure, as corresponding person under inspection 10 object registration information and be stored in object registration information storage part 800, and the object registration information that this has stored is input to data reception portion 630, data merging portion 700 and safety whether mode decision portion 6.
