Specifically, the sound for including life noise in voice data information and issuing in certain situations, for example, sound
Including the voice of old man, fan sound and walk process issues in doors sound in data information.It is appreciated that old man
Voice, fan sound and walk process issues in doors sound have a value range, in the value range and daily life
Common acoustic value range is similar.And the decibel value of the sound issued in certain situations then with the range of sounds value in daily life
It is different.For example, default decibel range refers to the range of the decibel value of sound in daily life, decibel range is preset at 10 points
Shellfish~60 decibel.For example, referring to that article falls such as teacup on low and falls in the sound lowly issued, for another example, table under particular condition
Son or chair fall on the ground sending the sendings such as sound sound it is all different with common acoustic value range, particular condition issues
The decibel value of sound out it is higher and occur frequency it is less.For example, the range of the decibel value of the sound issued under particular condition
At 70 decibels or more, and the sound compared with high-decibel only can be just issued when meeting similar situation.Therefore, pass through judgement sound
Whether the sound decibel value in sound data information is more than default decibel range, thus accordingly judge old man detection zone whether
There is emergency, for example whether because uncomfortable cause the cup taken on hand to be fallen down, or occur fainting and falling down
Deng to timely understand old man in the actual conditions of detection zone.
Further, the sound decibel value judged in voice data information whether be more than default decibel range step
Suddenly, comprising: extract the sound decibel value in voice data information；Judge whether sound decibel value is located in default decibel range；
If so, the sound decibel value in voice data information is in default decibel range；If it is not, the then sound in voice data information
Decibel value exceeds default decibel range.For another example, whether the sound decibel value judged in voice data information is more than default point
The step of shellfish range, comprising: the sound decibel value in extract real-time voice data information；It is pre- to judge whether sound decibel value is located at
If in decibel range；If so, the sound decibel value in voice data information is in default decibel range；If it is not, then sound number
It is believed that the sound decibel value in breath exceeds default decibel range.In this way, when the sound decibel value in voice data information is default
Illustrate that old situation is good when in decibel range, and the sound decibel value in voice data information exceeds default decibel model
Then illustrate that old man's present case is possible to emergency occur when enclosing, needs further to verify.For example, when judging sound number
It is believed that it is that when being, video information is sent to movement that whether sound decibel value in breath, which is more than the judging result of default decibel range,
Terminal.When sound decibel value in voice data information exceeds default decibel range, directly video information is sent to mobile whole
The case where end, user can check old man in detection zone at this time by mobile terminal.
Further, the sound decibel value judged in voice data information whether be more than default decibel range step
Suddenly, comprising: extract the sound decibel value in voice data information；Judge whether sound decibel value is located in default decibel range；
If so, the sound decibel value in voice data information is in default decibel range；If it is not, the then sound in voice data information
Decibel value exceeds default decibel range.For another example, whether the sound decibel value judged in voice data information is more than default point
The step of shellfish range, comprising: the sound decibel value in extract real-time voice data information；It is pre- to judge whether sound decibel value is located at
If in decibel range；If so, the sound decibel value in voice data information is in default decibel range；If it is not, then sound number
It is believed that the sound decibel value in breath exceeds default decibel range.
Step S105: judge whether the pressure value in first pressure data information changes within the scope of preset pressure value.It can
Knowing step S105 is to judge old man whether sleeping time in bed in order to corresponding, because of the first pressure when old man crouches and plows in bed
Pressure value in data information will change.Known to step S105 be sound decibel value in voice data information pre-
If being to carry out in decibel range, i.e., not big enough the decibel value of the sound issued after the cup that old man takes on hand is fallen down is not high enough,
Or old man when occurring fainting and falling down sound be not above when default decibel value, continue further monitoring confirmation.
Specifically, the pressure value in first pressure data information refers to that the pressure sensor being arranged on bed surface is acquired
The pressure value arrived.Such as when sleeping time of old man in bed when pressure sensor be under pressure pressing, preset pressure will be collected at this time
The pressure value being worth in range.For example, preset pressure value range is that pressure value is greater than zero；For another example, central processing unit can be according to more
The historical data of pressure value in secondary collected first pressure data information obtains the upper limit of the preset pressure value range under
Limit obtains the upper and lower bound of more scientific preset pressure value range, in this way to judgement by the study to historical data
It is that more for science with accurately, energy is practical that whether the pressure value in first pressure data information changes within the scope of preset pressure value
Evaluation response goes out the current activity condition of old man.
For example, bed surface is provided with multiple first pressure sensors, the pressure signal that each first pressure sensor generates
Collection be combined into first pressure data-signal, first pressure data-signal will be generated when such old man lies in bed, wherein first pressure number
It is believed that number including the collected signal of multiple first pressure sensors, so it is possible to prevente effectively from unnecessary error, such as always
People has put the pressure that a quilt can also generate in bed, should avoid the pressure generated because having put a quilt in bed at this time
Power is also identified the situation of processing.
Whether the pressure value to judge in first pressure data information more accurately changes within the scope of preset pressure value,
Whether the pressure value judged in first pressure data information becomes within the scope of preset pressure value in one of the embodiments,
The step of change, comprising: extract each pressure value in first pressure data information；Judge whether each pressure value is equal to zero；
If it is not, then the pressure value in first pressure data information changes within the scope of preset pressure value；If so, first pressure data are believed
Pressure value in breath does not change within the scope of preset pressure value.Only have each pressure value in first pressure data information equal in this way
It just show that the pressure value in first pressure data information does not change within the scope of preset pressure value when equal to zero, shows old man at this time
Sleeping plow is rested in bed.
Step S106: if it is not, then judging whether the pressure value in second pressure data information becomes in preset time range
Change.Know that step S106 is to judge whether old man is made on chair after leaving bed in order to corresponding, because when old man leaves
Pressure value after bed when on chair in second pressure data information will change, so as to judge old man's present case
It is safer.
Specifically, in the pressure value judged in first pressure data information by step S105 whether in preset pressure value
In range the step of variation after, when the judging result of step S105 is no, i.e., the pressure value in first pressure data information is not
When changing within the scope of preset pressure value, step S106 is just executed, the activity condition corresponding to old man is exactly after old man leaves bed,
It may be made on chair, it is also possible to movable within the scope of other of detection zone.In this step, in second pressure data information
Pressure value refers to the collected pressure value of the institute of the pressure sensor on chair, which is arranged in, to be shown.Such as it after old man leaves bed, does
Pressure sensor is under pressure pressing when on chair, the pressure value that will be collected within the scope of preset pressure value at this time.For example, pre-
If range of pressure values is that pressure value is greater than zero.For example, central processing unit can according to multi collect to old man leave bed after do
The upper and lower bound of time range on chair obtains more scientific preset time model by the study to historical data
The upper and lower bound enclosed, to the pressure value judged in second pressure data information, in preset time range whether variation is in this way
More science can go out the current activity condition of old man by evaluation response conscientiously with accurately.
In order to more accurately judge after old man leaves bed whether on chair, the judgement in one of the embodiments,
The step of whether pressure value in second pressure data information changes in preset time range, comprising: extract second pressure number
It is believed that each pressure value in breath；Judge whether partial pressure value is greater than zero in each pressure value in preset time range；If
It is that then the pressure value in second pressure data information changes in preset time range；If it is not, then in second pressure data information
Pressure value do not change in preset time range.In this way when detecting each pressure value in second pressure data information,
It is obtained when partial pressure value is greater than zero in each pressure value in preset time range: after old man leaves bed, being made on chair and rest,
The situation of old man is comparatively safe at this time；When detecting each pressure value in second pressure data information, in preset time
It is obtained when each pressure value is respectively less than zero in range: it is movable within the scope of other of detection zone after old man leaves bed, at this time always
The situation of people be it is relatively risky may for example fall, need at this time user further voluntarily according to the information of video carry out
Whether the observation in monitoring range so can more accurately judge after old man leaves bed on chair.
Step S107: if it is not, video information is then sent to mobile terminal.
Specifically, in the pressure value judged in second pressure data information by step S106 whether in preset time model
After the step of enclosing interior variation, when the judging result of step S106 is no, i.e., the pressure value in second pressure data information does not exist
In preset time range when variation, step S106 is just executed, the activity condition corresponding to old man is exactly possibility after old man leaves bed
It is made on chair, it is also possible to movable within the scope of other of detection zone.And it is desirable that old man, which leaves after bed to being made on chair,
A period of time, if the pressure value in second pressure data information does not change after this period of time, it can be said that bright
Old man is not made on chair after leaving bed, then at this time the situation of old man be it is relatively risky may for example fall, because
Video information is sent to mobile terminal in this case by this, and user can observe the old of detection zone at this time by mobile terminal
The activity condition of people, to confirm whether old man occur safely accidentally tumble or other fortuitous events.
It is described by vision signal in one of the embodiments, in order to which vision signal is preferably sent to mobile terminal
The step of being sent to mobile terminal, comprising: foundation is connect with the long-distance communication network of mobile terminal；Vision signal is passed through long-range
Communication network is sent to mobile terminal.It is connect in this way by preparatory with the long-distance communication network of mobile terminal, guarantees that network is logical
Vision signal is remotely sent to mobile terminal in the case where smooth, so that user can receive video at the first time
Signal and the activity condition for observing old man in time can be handled in time when occurring unexpected, and then be better achieved to old man
Monitoring.
Step S108: the sound play instruction sent by mobile terminal is received, and is raised according to sound play instruction control
Sound device plays preset audio information.
Specifically, user can view the picture signal of detection zone by mobile terminal after step S107, at this time
When the old man in detection zone is in an emergency, and user is in strange land, and old saying has that a relative far off is less help than a neighbour close by, leads at this time
