Preferably, described warning message can comprise the locating information that described GPS collects.
As shown in Figure 2, the present invention also provides a kind of detection alarm method of falling, and adopts the above-mentioned detection alarm device that falls, and may further comprise the steps:
(1) described acceleration transducer carries out the 3-axis acceleration Data Detection, and sends described 3-axis acceleration data to described micro-control unit;
(2) described micro-control unit judges whether to fall, if, execution in step (3) then, if not, execution in step (1) then;
(3) described GPS sends locating information to described global system for mobile communications;
(4) described global system for mobile communications is reported warning message to background server.
Preferably, in the described step (4), described warning message can comprise the locating information that described GPS collects.
In actual the use, of the present inventionly fall detection: the acceleration information of real-time collecting acceleration Sensor, in case situation occurs falling, detect and confirm to fall generation by special algorithm.
Sound and light alarm: after falling situation affirmation generation, system should send the sound and light alarm prompting to the external world.
Wireless reporting: fall situation in case take place, system need pass through wireless mode, and (GPRS GSM) reports warning message and positional information to background server, and the means (Call) of instant contact are provided.
Inform the position: implement to fall on the warning message to give the correct time, the positional information of falling need be provided simultaneously.
Main body of the present invention is the MC9S08QG4 of the Freescale of low-power consumption, the MT6223D GSM chip of the GPS chip of Sirf and MTK, gather real-time acceleration information by acceleration sensor, after the MC9S08QG4 analyzing and processing, give a warning to the backstage by the GSM chip, warning message can comprise the GPS locating information that GPS collects again.Simultaneously, send acousto-optic hint on LCD and Speaker, alarm set possessor or near crowd process.Need get in touch with the gsm communication module as the backstage, can realize call function by Mic and Speaker.
In falling pick-up unit, the GSM part protocol software existing presetting when dispatching from the factory in the gsm module, that here done mainly is management and Mcu, communication between the GPS in time responds the warning of falling of Mcu, and starts and accepts GPS information, the management peripheral modules, reporting information etc.
The relative total system of GPS module is comparatively simple, and its main flow process is the positioning command of waiting for that gsm module is assigned, and locating information is reported to gsm module.
Peripheral modules comprises the outer add-on assemble that is connected on the gsm module, comprises LCD, Keypad, Speaker, Mic etc.Lcd wherein, Speaker mainly are responsible for reporting to the police when taking place when falling, and start one and have overtime sound and light alarm prompting, if when failing to obtain handling in time-out time, initiatively get in touch the call number of background server or prior setting.KeyPad, Mic are mainly used in provides call function, operating function.
Falling detection module is the core of this device, mainly comprises the data acquisition of acceleration transducer, falls the analysis of algorithm etc.The basis of falling detection is the collection of data, and employed here acceleration transducer is the MMA7361L of Freescale company.MMA7361L provides X, Y, and the Z 3-axis acceleration detects, and 1.5g is arranged, the selection of two ranges of 6g.What consider the main detection of this device is the situation of falling of human body, so 1.5g is more suitable range.
Data acquiring frequency is the another one emphasis, and underfrequency meeting obliterated data causes in time detecting and falls.Be set at 125Hz in this device.Falling of human body can occur under the multiple situation, in walking, in the process of upward going downstairs, ascends a height or bunk bed, and the consciousness of losing is freely fallen, and is engaged in particular job etc.But these are fallen some common features are often arranged.
Human body is fallen take place before with take place after attitude do and analyze and the discovery of contrast back, generally, human body all is for the attitude of standing before falling, and lies down or lean to state and often be in after falling, and is in consequence when lying down state after falling often seriously in other state.Therefore, in analyzing falling process, the attitude variation before and after falling merits special attention very much.
Other some keys of falling detection are the accelerating curve that falls when taking place is carried out reasonable analysis, therefrom decomposite the acceleration change characteristics of falling when taking place, and, reduce the target of rate of false alarm to carry out analog capture near real mathematical model as far as possible, to reach improving falling verification and measurement ratio.
What provide as shown in Figure 3, is that a width of cloth typically falls the acceleration plots that overall process takes place.Wherein, on behalf of human body, state A, E be in the attitude of standing; On behalf of human body, state B be in to fall state; Bump after state C representative the falling end; On behalf of human body, state D be in the state of lying down.
Analyze from the graph and can learn:
When human body is in when standing attitude, because the relation of fall detection device wearing position on one's body human body, three acceleration is always inequality, but meets certain rule basically, as an axle always being arranged because of D-factor and gravity direction near normal.
When human body is in when falling, three acceleration is subjected to gravity effect simultaneously, and unique difference is the difference because of direction, and suffered partical gravity is not of uniform size.
Fall the impact events that occurs when finishing, tend to cause a certain peak value that the primary acceleration variation occurs in three.
When human body is in when lying down state, three accekeration has when standing attitude obviously different.
Some above-mentioned key element has constituted the whole main body of falling algorithm, can judge the most situation of falling.Certainly, the acceleration threshold values of the time interval between each state and each state just can draw a relatively reasonable setting after all needing to do repeatedly test.As the state A before falling, when human body was in different motion states, its curvilinear motion was comparatively complicated, how to set reasonable range and makes it distinguish test and validation repeatedly with real falling.
According to the pick-up unit that falls of such scheme design, in our proof scheme, estimate well, be the form of the part of test results of intercepting below.
Human body entity test: each object test test 5 times obtains this object and report rate under this parameter.
The rate of false alarm test:
| Rate of false alarm | Object 1 | Object 2 | Object 3 | Object 4 | Object 5 |
| Upstairs (20 grades of steps) | Pass | Pass | Pass | Pass | Pass |
| Downstairs (20 grades of steps) | 1 | Pass | 1 | Pass | Pass |
| Normal walking (100M) | Pass | Pass | Pass | Pass | Pass |
In summary, the accekeration of the human body of the present invention by detecting wearable device three directions when motion is realized detection that human body is fallen, and is in time reported by subsidiary communication module, reaches the human body purpose that early detection reports of falling.
Above-described embodiment only is used to illustrate technological thought of the present invention and characteristics, its purpose is to make those skilled in the art can understand content of the present invention and implements according to this, can not only limit claim of the present invention with present embodiment, be all equal variation or modifications of doing according to disclosed spirit, still drop in the claim of the present invention.
