It falls down, is then sounded the alarm by buzzer, and to assigned number short message and made a phone call by Goouuu_A6, cause household in family
Or road pedestrian's note that and sending location information allows household to be checked on mobile phone A pp.
The utility model specific performance index：Cruise duration：24 hours or more；Weight：100g or so；Charging time：It will
It is placed in general wireless charging board or is charged using general Micro USB interfaces, and the charging time is about 1 small
When, when red expression is being charged, and green light expression has been charged full, it is not recommended that state is remained operational while charging, to electricity
It pond can be lossy.
The utility model is as follows using algorithm：
The elderly falls down process compared with other normal motions.With apparent feature, especially in human body row
Variation in terms of for, upper body trunk, which closes the variation of deflection angle and resultant acceleration variation, when Falls in Old People can compare proper motion
General process in state is apparent much larger.
The elderly falls down the especially fast of behavior generation usually in 1-2 seconds.When the elderly falls down, can with ground or
The violent shock of other articles progress even will appear multiple impact and resultant acceleration curve made to have the shake of multiple wave crests for it
Swinging type may be more than 2 seconds if there is the used time that multiple impact the elderly falls down, such as falls down well in stair soil and roll down
Shi Duoci makes impact with the ground, so taking deflection angle variation and the resultant acceleration before the point of at the time of after resultant acceleration acute variation
It is combined with each other judgement.
First after detecting that resultant acceleration is more than a certain setting value, judges into resultant acceleration is fallen down, be delayed after 1s, obtain
Take multiple data.Be 50ms in view of each data break that obtains, times of acquisition are set to 16, i.e., after the 1s that is delayed, resultant acceleration
It all tends to be steady in subsequent 1.8s（Less than 1.2）, you can it is judged as meeting the resultant acceleration condition fallen down.
Entry angle judges after meeting the resultant acceleration fallen down.First, it while product is activated and is initialized, obtains
Initial acceleration information calculates the angle value of 3 initial axis and horizontal plane using this data as initial angle angle value.Afterwards full
Foot falls down the angle that 3 axis and horizontal plane at this time are calculated under conditions of resultant acceleration requires, when the angle and initial angle angle value
When absolute difference is more than 50 °, it is judged as meeting the angle conditions fallen down.When above-mentioned two condition is satisfied by, we can recognize
It is set up to fall down, rear triggering alarm function.
The mode for obtaining location information and movement locus is：The LAC for the respective base station for obtaining target is instructed by AT
With Cell ID information, base station information is achieved, when old man fall down triggering alarm when, MCU by the base station information of newest archive with
The mode of short message is sent to monitoring center by gsm module（Specified target mobile device）, after monitoring center receives short message
The data frame short message whether monitoring objective is sent first determined whether, is then therefrom read if it is the data frame short message that monitoring objective is sent
Go out the number of monitoring objective（Phone number）, time and base station information, monitoring center passes through with calling Baidu according to mobile phone A pp
Figure position location API shows the position of target, and household or monitoring side is facilitated to navigate to the position that old man falls down.
Mobile phone A pp provides the selection for showing movement locus simultaneously, and mobile phone can be assigned instruction to alarm in the form of short message, be asked
Ask motion track information, MCU that the base station information of all archives is fed back to monitoring center so that monitoring center can obtain monitoring
The movement locus of target.This design just comes into force when only having monitoring objective to send out alarm, and when not having alarm, display gesture function is not
Can being monitored, center is enabled to be enabled, and can protect the privacy of monitoring objective in this way.
Cell-phone customer terminal is developed based on Baidu map Android positioning SDK, Baidu map Android positioning
SDK provides the multiple positioning modes such as GPS, base station, WiFi, earth magnetism, bluetooth, sensor, is suitable for indoor and outdoor a variety of localization fields
Scape has outstanding positioning performance：Positioning accuracy is high, coverage rate is wide, network location request flow is small, locating speed is fast.It is carried
The base station location function of confession is well suited for the requirement of this works, and set positioning SDK freely opens to the outside world, and interface use is without number
Limitation, therefore the cell-phone customer terminal of this works selects Baidu map positioning SDK to be developed.
When the utility model is measured according to the method for following table.
According to test result, improved in the way of following table.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
