Table 4

When old solitary people 1 enters the sensing range of sensor 2, sensor 2 sends perceptual signal to sensing monitor portion 3, when in case sensing monitor portion 3 detects from the signal of sensor 2, sensing monitor portion 3 sends the information that perceives and requires to carry out reasoning to reasoning part 4, after reasoning part 4 is received the reasoning request, at first obtain old solitary people 1 table at present just in the information in which room from being provided with of the corresponding information storage part 5 of room and sensor 2, activity according to the people has characteristics such as sequential continuity and regularity, the special time period of the old solitary people 1 that writes down from information storage part 5, the activity statistics of every day carries out the condition trend prediction and peace denys that situation is carried out reasoning; When reasoning part 4 is inferred as abnormal conditions, to further abnormal conditions be quantized and classify, from the contact table of information storage part 5, got in touch with the information such as address of object, liaison method and old solitary people 1 again according to the classification results of abnormal conditions accordingly, sent the unexpected message of old solitary people 1 then by communication facilities 6 through network 7 to contact object 8; After contact object 8 obtains the unexpected message of old solitary people 1, provide instant, suitable rescue or service to the doorstep.This old solitary people life support method and device are also supported the autonomous warning and the request service of old solitary people 1 simultaneously, old solitary people 1 can communication facilities 6 sends the solicited message of old solitary peoples 1 through network 7 to contact object 8, graphic button that some old men understand easily, that have request service symbol is set on communication facilities 6, press certain button just sends solicited message from old solitary people 1 to specific contact object 8, obtain the autonomous warning and request of old solitary people 1 when contact object 8 after, provide instant, suitable rescue or service to the doorstep.

The data acquisition of the daily routines amount of old solitary people 1 is the first step element task of system; there have been a large amount of activity data just can carry out reasoning and judging; native system is by human body sensor 2; the statistics old man is at different periods and the activity in the chummery not; form historical act gauge rule; and compare with current activity; make supposition; with Fig. 1 is information acquisition and the action continuity check module that example illustrates Fig. 4; Fig. 1 is old man's the living space and the arrangement plan of actual human body sensor; because sensor and each room in each room of old solitary people 1 have reference numeral as shown in table 2; when old solitary people 1 enters the sensing range of sensor 2; sensor 2 sends the sensed impulses signal to sensing monitor portion 3; system obtains the system clock time and judges and send from which room (sensor) when detecting this pulse signal; the number of times that sends with this sensor of formula (1) statistical computation

$A_{\mathrm{total}}^{t\left(i\right),\mathrm{sensor}}=A_{\mathrm{total}}^{t\left(i\right),\mathrm{sensor}}+1---\left(1\right)$

A in the formula (1) _Total ^{T (i), sensor}It is the umber of pulse that statistical computation is sent from which room (sensor).

In order to obtain the life activity quantitative statistics counter value A of this certain time period and certain activity space _Total ^{T (i), sensor}In each living space (room) of old man, human body sensor to be installed, the installation of sensor should be avoided the misoperation that some house pets (cat, dog etc.) cause, it more than 0.4 meter sensing range, and to carry out reference numeral to each living space (room) of everyone body induction sensor and old man, shown in the table 2.A _n ^{T (i), sensor}The mean activity amount in certain room in the section between having represented at a time, this value has reflected on average the proportion in this space in the activity time in room and old man's daily life, the same day old man the total activity amount and original average total activity amount more do not take place under the big situation of change, if actual value A _Total ^{T (i), sensor}Taken place to depart from more greatly with this value, the variation of the activity center of gravity on old man same day has been described.

Below in conjunction with the action continuity judge module flowchart text old solitary people family of Fig. 5 about the successional judgement of taking action: at first, be that example illustrates with Fig. 1, figure is solitary's the living space and the arrangement plan of actual human body sensor.Sensor and each room reference numeral in each room is as shown in table 2, can obtain the system topology figure of Fig. 2, each node is represented a room in Fig. 2, and two nodes link to each other, and promptly represent these two rooms directly to be communicated with.As shown in fig. 1, this residence one has six differentiable spaces and adds a space outdoors, and five gateways are arranged in the room, enters to have only a gateway within doors.Wherein (1,2), (2,3), (2,7), (2,4), (3,5), (3,6) are communicated with.A character matrix can be represented all top information, wherein 1 expression is communicated with, 0 expression be the space with the space between directly be not communicated with, therefore can come the topology diagram of presentation graphs 2 with the Metzler matrix shown in the table 4, in 7 * 7 matrix M of table 4, if M[i] [j]=1, expression node I links to each other with j; If M[i] [j]=1, expression node I links to each other with j; If M[i] [j]=0, expression node I and j are disjunct.People's activity all has continuity and continuity, the active sequences that produces such as certain solitary's action is A (1,2,3,6,3 ...), can judge by looking into the connection matrix table whether two adjacent active sequenceses are to meet the continuity principle according to this active sequences, that is to say whether two adjacent activity spaces have the jump situation to take place.Above-mentioned active sequences A (1,2,3,6,3 ...), at first being listed as the value of obtaining from the 1st row and the 2nd is 1 to meet the requirements, secondly being listed as the value of obtaining from the 2nd row and the 3rd is 1 also to meet the requirements, being 1 equally also to meet the requirements from the 3rd row and the 6th row value of obtaining once more, is 1 from the 6th capable and the 3rd row value of obtaining at last ... above-mentioned assay all is 1, and expression meets the requirement of continuity and continuity.If there is the jump situation to take place, may be thought of as following several situation: the living space that 1) has other people to enter the old man (particularly will cause and pay special attention to night, having the people invades), when simultaneously when two different activity spaces are found detected information is arranged, then possibility is just very big; 2) senser element or line related are malfunctioning, do not detect the activity of human body.Therefore under normal circumstances can obtain the old man go out the active sequences A1 that goes out (... 2,7), the old man active sequences A2 (7,2 that goes out to go home,), under the situation that the active sequences A1 incident that the old man does not go out produces, active sequences A2 (7,2 has taken place,), the people that can be inferred as except the old man enters within doors; Identifier list need be set to be shown with other people and to enter within doors by door; When find that such active sequences A3 is arranged (... 2,7,2,), the expression old man has gone to out an Xiamen, and this is that the symbol that also should set up standard is 1, and the expression incident of opening the door takes place, in that this standard symbol is arranged is under 1 the situation, judge the situation of following appearance: 1) when finding to have in the same time action of many places sensor or jump phenomena occurring, can think to have the visiting or attendant of people to make house calls, at this moment system stops to calculate old man's activity; When 2) above-mentioned situation not taking place, system thinks that the old man has just opened an Xiamen, has taken thing from the doorway.Therefore the judgement that has an action noncontinuity incident to take place under the situation that the incident of at first not opening the door in alarming anti-theft module process flow diagram shown in Figure 6 takes place, under the situation that above-mentioned condition satisfies, the time period of this incident of generation also will be judged by system, if under situation about taking place night, it is very high to steal difficult possibility, and system takes to report to the police immediately and notifies old man's relevant guardian simultaneously.

Because each old man's habits and customs; life style and health status exist individual difference; for current activity and normal activity amount at ordinary times being compared; system at first will obtain certain old man's present life pattern; there is a life pattern learning phase in system the operation incipient stage; the reference frame of while along with its normal activity amount at ordinary times of age growth of old man also can change; also need constantly to upgrade this comparison reference; in conjunction with relevant certain old man of the recursion module flowchart text of Fig. 7 at a time between the life activity amount of section and certain activity space calculate; formula (2) is the computing formula of the recurrence average value of the life activity amount of certain time period of calculating and certain activity space; formula (3) is the computing formula of the recurrence average value of the life activity amount of certain time period of calculating, and this formula is a lowpass digital filter in fact

$A_{n+1}^{t\left(i\right),\mathrm{sensor}}=(1-k)*A_n^{t\left(i\right),\mathrm{sensor}}+k*A_{\mathrm{total}}^{t\left(i\right),\mathrm{sensor}}---\left(2\right)$

$A_{n+1}^{t\left(i\right)}=(1-k)*A_n^{t\left(i\right)}+k*\mathrm{\Σ}{A}_{\mathrm{total}}^{t\left(i\right),\mathrm{sonsor}}---\left(3\right)$

K is a coefficient, less than 1, in big (between 0.5 to 0.9) that learning phase k value can be got, wish learning time weak point the k value can be got big, and detecting littler (between 0.001 to 0.009) that unusual stage k value will be got in system, the mean activity quantitative changeization of mainly considering the old man is a process slowly.

Judge old man's abnormal conditions, this judgement relatively is based upon relatively on the basis, because old man's physical condition and the change that changes of seasons all can influence the activity statistical value, but this change generally be slowly, regular, therefore to upgrade this relatively reference value dynamically, so under situation about not noting abnormalities, also will with the recursion module process flow diagram of Fig. 7 of system in handle the same A that constantly upgrades _Min ^{T (i)}, A _Max ^{T (i)}, A _n ^{T (i)}Value; In general the both regular while of old man's activity also has temporal ambiguity, so-called temporal ambiguity is meant that certain action (such as getting up) of old man is not all to take place on time every day, therefore relatively also to have a look the activity and the activity of time period in night of the front and back of section sometime in the activity in some hour, Fig. 9 for the activity that calculates each time period activity of old man and each time period, each activity space and Exception Type judge module process flow diagram about the activity comparison module: with present stage activity A _Total ^{T (i)}, sum ^I+1 _Active, sum ⁱ _Active, sum ^I-1 _ActiveWith historical record A _Min ^{T (i)}, A _Max ^{T (i)}, A _n ^{T (i)}, sum ⁱ _AverageCompare,

In the formula:

Sum ^I+1 _ActiveBe Duan Houyi activity quantitative statistics counter value sometime sometime.

Sum ⁱ _ActiveBe the statistical value of activity of section sometime.

Sum ^I-1 _ActiveBe the activity quantitative statistics counter value sometime of section reach sometime.

Sum ⁱ _AverageBe the recurrence average value of activity of section sometime.

The sum that calculates when (4), (5), (6) formula ^I+1 _Active, sum ⁱ _ActiveAnd sum ^I-1 _AvtiveThe sum that three values calculate with (7) formula respectively ⁱ _AverageCalculate their relative value, because people's activity mainly concentrated in the time period on daytime, therefore the present invention mainly investigates the activity situation of time period on daytime, minimizing situation according to activity will be divided into different levels unusually, the big more unusual rank of reduction is just high more relatively, the actual count activity of certain time period and the relative quantity of mean activity amount are calculated and are calculated with (8), (9), (10) formula

Day _Activity1＝(sum ⁱ⁺¹ _active-sum ⁱ _average)/sum ⁱ _average*100???(8)

Day _Activity2＝(sum ⁱ _active-sum ⁱ _average)/sum ⁱ _average*100?????(9)

Day _Activity3＝(sum ^i-1 _active-sum ⁱ _average)/sum ⁱ _average*100???(10)

The value Day that from above-mentioned (8), (9), (10) formula, calculates _Activity1, Day _Activity2, Day _Activity3In try to achieve minimum value Day _ActivityTo judge whether also that in addition the people comes to visit, whether goes out, by day time period whether, also to have a look simultaneously the activity statistical value (being that example adopted from late 9 o'clock to 5 o'clock mornings in the present invention with the winter) of time period evening before that day, therefore following computing formula is arranged

${\mathrm{Night}}_{\mathrm{Activity}}=(\underset{21}{\overset{5}{\mathrm{\Σ}}}{{\mathrm{sum}}^i}_{\mathrm{active}}-\underset{21}{\overset{5}{\mathrm{\Σ}}}{{\mathrm{sum}}^i}_{\mathrm{average}})/\underset{21}{\overset{5}{\mathrm{\Σ}}}{{\mathrm{sum}}^i}_{\mathrm{average}}*100---\left(11\right)$

Work as Night _Activity＞=time and Day _ActivityThought a kind of abnormality at-10 o'clock, cause the rest on daytime, unusual information is set owing to evening is movable; Work as Night _ActivityOther were according to Day in＜5 o'clock _ActivityValue (10 ,-20 ,-30 ,-40 ,-50) abnormal conditions classify Day _Activity＜=-50 o'clock be severely subnormal ,-40＜=Day _Activity＞-50 o'clock be obviously unusual ,-30＜=Day _Activity＞-40 o'clock be medium unusual ,-20＜=Day _Activity＞-30 o'clock be part unusual ,-10＜=Day _Activity＞-20 o'clock for having unusual, 0＜=Day slightly _Activity＞-10 o'clock for classification such as noting.As 5＜=Night _ActivityOther were according to Day in＜10 o'clock _ActivityValue (10 ,-20 ,-30 ,-40 ,-50) abnormal conditions classify Day _Activity＜=-50 o'clock be medium unusual ,-20＜=Day _Activity＞-40 o'clock be part unusual ,-10＜=Day _Activity＞-20 o'clock for to note, 0＜=Day _Activity＞-10 o'clock is classifications such as abnormality.Above-mentioned data are default initial values, move an end after the time in system, and the user can revise or adjust the size of these numerical value according to statistics, so that more can reflect old man's individual difference and because the deviation that seasonal variations produces.

When system has been judged as when unusual or old man when initiatively sending request, system changes the request module process flow diagram of Fig. 8 over to, at first to read solicited message, secondly according to obtaining asking essential informations such as classification and contact object 8 in the solicited message table of this solicited message from storage area 5, then will be according to the essential information of some the old man families that send to contact object 8 that are provided with in the system, as the address, information such as telephone number send to contact object 8 together with abnormal information or old man's solicited message, so that obtain timely and suitable support or rescue, the information of these transmissions can be voice, multimedia messagess such as text, the network that sends can adopt various communication networks, such as public post and telecommunications net, internet, the various networks that can transmit information such as cable television network, when system to contact after object 8 sends abnormal information, system constantly requires to reply to the high information of exception level, after contact object 8 is confirmed, process information is write in the storage area 5, so that the affirmation responsibility of back and as the foundation of payment services expense.

Install every through after a while (such as one month) preserve the recurrence average value A of the life activity amount of certain time period _n ^{T (i)}, by the recurrence average value A of a series of life activity amount _n ^{T (i)}Can obtain the activity averaged curve figure when certain period finishes, just can analyze old man's health status by a series of activity averaged curve figure that obtain every month by the trend of moving towards of activity averaged curve figure.

This device is not reported to the police peace active, passive-type and is combined; the peace that has improved system denys the reliability of information; brought into play the do not report to the police advantage of form of various peaces; can avoid because the weakness of single form system; this device has solved individual privacy protection problem preferably simultaneously; just just send abnormal information to contact side when abnormal conditions take place the old man, the various trifling matters of everyday lifes of old man and individual privacy obtain respecting, and the energy while is to a plurality of contact monitoring department transmission abnormal information.Can select the not configuration of warning system of old solitary people peace according to various conditions during actual the use.Adopting this device is the quality that has improved life to the elderly, can work contentedly and can fulfil one's duty to one's parents children, can alleviate the burden of social pension to country.This method can not only be used in old solitary people family and can be applied in apartment for elderly people.This has positive effect to the unusual timely corresponding measure of taking of early detection, the health of holding old solitary people, healthy trend and life.

Claims (3)

1, a kind of household safe and security equipment for solitary old person, it is characterized in that: comprise sensor, sensing monitor portion, reasoning part, be used to store the activity statistics old solitary people special time period, every day information storage part, be used for getting in touch with the communications portion that object is got in touch with extraneous, each sensor is connected with the sensing monitor portion, sensing monitor portion output terminal is connected with the input end of reasoning part, and the output terminal of described reasoning part is connected with communications portion;

The external door in each room and room all is equipped with sensor in the family of described old solitary people, and when old solitary people enters the sensing range of sensor, sensor sends perceptual signal to the sensing monitor portion;

The signal of described sensing monitor portion receiving sensor partly sends the information that receives and sends to reasoning and requires reasoning partly to carry out the request of reasoning;

Described reasoning part sends to the information of being gathered in the recursion module, and described recursion module is stored in described storage area with the recurrence average value of certain time period and each room activity amount of certain time period;

Whether reasoning as described partly judges the signal of described sensor from external door, if, whether human perceptual signal is arranged simultaneously in the different room of the time period after judging, if having, judge that then that the people is arranged is visiting, do not judge unusually; If no, then being judged as the old man returns;

As described time series signal from the room to external door, do not have afterwards to find that the human perceptual signal of getting back in the room is arranged, judge that then the old man goes out, do not judge unusually;

The time series of signal as described is not outer outgoing event, and described reasoning judges partly whether the described time period is the time in night, if, then do not judge unusually, the activity of time period in night is stored in described storage area;

If the period of received signal is not the period in night, reasoning partly judges whether timing statistics, if to timing statistics, then the total activity amount in the described timing statistics section is partly calculated in reasoning, and the recurrence average value of described total activity amount and storage area is made comparisons; Reasoning partly is inferred as abnormal conditions and sends alerting signal, and sends to different contact objects according to the described alerting signal of big young pathbreaker of abnormality degree by described communications portion.

2, household safe and security equipment for solitary old person as claimed in claim 1, it is characterized in that: also include alarm, old man's signal of can initiatively filing a request, described solicited message sends to request module, judge the type of described solicited message, solicited message is sent to different contact objects according to different types.

3, as claim 1 or 2 described household safe and security equipment for solitary old person, it is characterized in that: smoke transducer, gas leakage detector are installed in described old man's the house.
