Technical field
The present invention relates to a kind of alarm method fallen down for human body, be applicable to the technical field of danger warning.
Background technology
Along with the arrival of social senilization, the quantity of China's elderly population is continuing to increase.The elderly, because inconvenient activity, health are fragile, is easy to cause injured even death because of falling down.But, when old man falls down, be all do not have kinsfolk at one's side in a lot of situation, therefore can not reported to the police timely and succour.The health status that how can detect old man in real time then becomes younger generation's especially problem of being concerned about the most of only-child's generation.
In prior art, the detection of falling over of human body is mainly undertaken by the acceleration transducer and angular-rate sensor that are worn on human body, such as warning system disclosed in Chinese patent CN101702258A is acceleration information by metastomium in human body and posture information, and whether the relation between comprehensive human body acceleration, pose, run duration three is carried out comprehensive descision human body and fallen down.But the pick-up unit in this patented claim is worn on metastomium (below neck, more than waist), and it dresses inconvenience.Especially old man in bed, if do not taken off by pick-up unit, then the wrong report of falling down can be sent; If taken off, then old man needs after wakeing up again to bring, and therefore uses very inconvenient.
In addition, employ angular-rate sensor in this patented claim and carry out integral operation to calculate the angle of pitch and the side rake angle of human body.This computing method are very complicated, and, the angle of pitch and the side rake angle of human body in fact just can not can be determined exactly by simple integral operation.This is because, need to determine path of integration when carrying out integral operation, and path of integration is general corresponding with the build of personnel when falling down.And the build of personnel is generally of all kinds, in different poses and with different expressions when falling down, therefore path of integration can not be determined exactly, thus also just the accurate angle of pitch and side rake angle can not be tried to achieve.
Moreover, in the disclosure in this patent, when automatic alarm judges to whether after falling over of human body, only judge that the acceleration of human body all directions in a period of time is all no more than a standard among a small circle, just prove that human body has lost the ability to act of emergency or lost consciousness.Because this determination methods only selects acceleration index to judge, therefore cause erroneous judgement than being easier to, thus cause wrong report.As can be seen here, utilize warning system disclosed in this patented claim to carry out falling down warning and not only operate inconvenience, but also very large rate of false alarm can be caused.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will be described in detail to embodiments of the invention.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
According to the alarm method fallen down for human body of the present invention, it utilizes smart mobile phone and Wearable wrist-watch to realize.Wherein, being provided with in smart mobile phone and Wearable wrist-watch can the communicator of communication mutually, such as bluetooth equipment.In addition, also acceleration transducer is provided with in smart mobile phone.When carrying this smart mobile phone, the acceleration of motion of acceleration transducer human body wherein can be utilized.Wearable wrist-watch in the present invention is provided with height sensor and acceleration transducer.
Acceleration transducer in Wearable wrist-watch is for detecting the acceleration of wearing site.When Wearable wrist-watch is worn on wrist, in fact what it was measured is exactly the acceleration of motion of human body wrist.During normal walking, the wrist of human body is swing, and the numerical value that acceleration transducer now detects is in the acceleration range of walking states.
When falling down, because health loses ground supports, human body is almost in state of weightlessness, and the acceleration that now acceleration transducer senses is approximately gravity acceleration g.In alarm method of the present invention, the acceleration transducer in the acceleration transducer in smart mobile phone and Wearable wrist-watch can verify mutually the acceleration value detected.Specifically, when the acceleration transducer in smart mobile phone detects the acceleration meeting and fall down feature, by communicator, result is pushed to Wearable wrist-watch, and compared with the acceleration value detected with Wearable wrist-watch, vice versa.When the acceleration value that the acceleration transducer in the acceleration transducer in smart mobile phone and Wearable wrist-watch detects matches, such as error is no more than 10%, is just for further processing.Consider the error that may exist, after the acceleration transducer in Wearable wrist-watch of the present invention and the acceleration transducer in smart mobile phone verify mutually, detect that the acceleration value of human body is 0.6-1.1g, when being preferably 0.8g-1.0g (, above meet the acceleration falling down feature), think and may fall down accident, thus trigger height sensor work.
Height sensor is for detecting the height change information of Wearable wrist-watch.When normally wearing, Wearable wrist-watch is positioned at the wrist portion of human body.When human body be in fall down state time, its distance leaving ground diminishes, and namely highly diminishes.In the present invention, height change threshold value, such as a 30cm are arranged to height sensor.When the height change numerical value detected is greater than height change threshold value, think that human body is in the state of falling down.
After falling over of human body, if its arm also has mobility, then the acceleration transducer in Wearable wrist-watch also can detect the numerical value of acceleration.Now, because the arm of human body also has mobility, the personnel that therefore fall down can oneself regain one's feet, and without the need to others help.But, if after falling down, human body lies in a comatose condition or arm loses mobility, then the acceleration transducer in Wearable wrist-watch just can't detect acceleration value or the acceleration value that detects very little, the personnel that now fall down just need the help relying on others just can regain one's feet.Therefore, in the present invention, an acceleration rate threshold is arranged to the acceleration transducer in Wearable wrist-watch, such as 0.1g, when the later acceleration value of falling over of human body being detected lower than acceleration rate threshold, thinks that human body lies in a comatose condition or arm loses mobility.
The signal conditioning package be arranged in Wearable wrist-watch processes the information that height sensor and acceleration transducer detect.When the height change numerical value that height sensor detects is greater than height change threshold value, warning system of the present invention is not send at once to fall down alarm, but continues to wait for a period of time.Such as, after waiting more than 30s, if the height change numerical value detected also does not recover regime values, when the acceleration value that the acceleration transducer simultaneously in Wearable wrist-watch detects is lower than acceleration rate threshold, then sends and fall down alarm.Certainly, the time of wait also can be arranged on other rational time, such as 20s, 40s or 60s etc.
Send after falling down alarm, utilize the communicator in Wearable wrist-watch to fall down warning information and positional information is sent in remote receiver.Like this, remote personnel just can be known the positional information of the personnel of falling down quickly and take corresponding measure to sue and labour in time.
According to alarm method of the present invention, early stage, when judging whether to fall down, is mutually verified the acceleration value of detection, rate of false alarm is dropped to minimum by the acceleration transducer in Wearable wrist-watch and the acceleration transducer in smart mobile phone.Secondly, alarm method of the present invention is by measuring the height after falling down and acceleration change judges that the human body after falling down is the need of help, and it does not need to carry out complicated integral operation, only comparatively just can be judged by simple numeric ratio.Again, alarm method of the present invention through certain time delay, will speed up number of degrees value and height change numerical value simultaneously as the judge index whether given the alarm, instead of just judges by means of only acceleration value after judging falling over of human body.Doing so avoids and only carry out using acceleration value as index judging that brought wrong report may.
In sum, adopt alarm method of the present invention, not only convenient to operation, and farthest can reduce rate of false alarm.
Although the embodiment disclosed by the present invention is as above, the embodiment that described content just adopts for the ease of understanding the present invention, and be not used to limit the present invention.Technician in any the technical field of the invention; under the prerequisite not departing from the spirit and scope disclosed by the present invention; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present invention, the scope that still must define with appending claims is as the criterion.
