Abstract
The invention discloses a mobile phone emergency calling method based on an acceleration motion sensor. Along with aging in the society, the quantity of mobile phones for the aged increases, but the addition of an emergency key to an ordinary mobile phone is far from being enough. An acceleration motion sensing device is arranged in terminals such as a mobile phone, and various motion behavior modes are analyzed, so that emergency calling operation can be performed conveniently, rapidly and accurately, and prompt help can be offered to the aged in case of an emergency.
Description
Technical field
The present invention relates to mobile phone alarm to seek help technology, particularly a kind of mobile phone urgent help seeking method based on acceleration motion sensor.
Background technology
The expansion that this segments market along with older mobile phone at present, there is the older mobile phone of multiple brand on the market, these mobile phones without exception add a flash appeal button, or be called SOS button, for in case of emergency waiting old man, cry for help to household fast.The design original intention of this button is fine, but it is found that slowly, and this button is easy to misoperation, brings unnecessary trouble, such as just must trigger emergency by 5 seconds in field so add again, or must fast continuously by 3 just triggering settings of crying for help.So, need emergency once really run into, old man, among acting hurriedly in a messy situation, might not make good use of this function.
Summary of the invention
For the problems referred to above, applicant is through Improvement, a kind of mobile phone urgent help seeking method based on acceleration motion sensor is proposed, realize user by the acceleration induction chip of embedded in mobile phone and in case of emergency carry out by action operation of seeking help, and mobile phone automatic decision emergency sending an SOS.
Technical scheme of the present invention is as follows:
Based on the mobile phone urgent help seeking method of acceleration motion sensor, comprise the steps:
First, in mobile phone, the action induction chip supporting acceleration detection is added, by the I of action induction chip
2c interface is connected with the CPU of mobile phone; The acceleration of the real-time detection of handset of action induction chip, is transferred to CPU; Then carry out User Defined action to seek help step, or automatic decision signal is sought help step;
Described User Defined action is sought help and is comprised the steps:
1-1), user is undertaken seeking help by mobile phone the setting of action;
1-2), under action induction chip real time record user arranges the mobile phone acceleration sequential of period in action of seeking help, and is transferred to CPU;
1-3), when next user makes similar action, the mobile phone acceleration sequential of user during this action under action induction chip real time record, and be transferred to CPU;
1-4), CPU to action induction chip detection to this action during and action of seeking help the mobile phone acceleration sequential of period be set contrast, judge this action and default action of seeking help whether consistent;
If 1-5) judged result shows that this action and default seeking help are kept strokes, mobile phone sends flash appeal signal; Otherwise do not send flash appeal signal;
Described automatic decision signal is sought help and is comprised the steps:
2-1), user carries out the setting of acceleration change rate-limit value by mobile phone;
2-2), action induction chip detection to the signal of mobile phone acceleration acute variation, and is transferred to CPU;
2-3), CPU judges whether the rate of change of this acceleration reaches the higher limit of setting;
If 2-4) judged result shows that the rate of change of this acceleration reaches the higher limit of setting, mobile phone sends flash appeal signal; Otherwise do not send flash appeal signal.
Advantageous Effects of the present invention is:
The present invention adds acceleration action induction device in the terminal equipments such as older mobile phone, and when there is emergency, old man can be sent an SOS by action., also can be judged specific action by acceleration movement device itself meanwhile, thus determine whether automatically send help signal.
Advantage of the present invention provides in the description of embodiment part below, and part will become obvious from the following description, or be recognized by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
Fig. 2 is the vertical direction acceleration change figure that acceleration action induction chip detection arrives.
Fig. 3 is the horizontal direction acceleration change figure that acceleration action induction chip detection arrives.
Fig. 4 be acceleration action induction chip detection to eminence fall time acceleration change figure.
Fig. 5 be acceleration action induction chip detection to knocked down time acceleration change figure.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
With reference to the flow chart of figure 1, first enforcement of the present invention will add the action induction chip supporting acceleration detection in mobile phone, and this type of chip is generally connected with the CPU in positioning and tracking device by I2C interface, in real time the acceleration of mobile phone is transferred to CPU.This type of chip is commercially available chip, and it is convenient to realize.
The present invention, according to the characteristic of acceleration action induction chip, achieves following two kinds of flash appeal modes:
One, User Defined action is sought help.
First, user, by the setting of mobile phone, carries out action setting of seeking help.Such as, user can be set to, in time stretching arm and wave, send help signal, or sends emergency when patting chest continuously with hand.
Cell phone system can note down the acceleration sequential that the acceleration action induction chip of lower user when inputting these actions is recorded.Due to the acceleration parameter during user action under acceleration action induction chip energy real time record, so the motion characteristic recording user that can be detailed, and when next user makes similar action, judge whether this action keeps strokes with default.
In one embodiment, user is set to hold mobile phone and upwards stretches arm and brandish more than 3 times continuously and then send an SOS.
First, mobile phone remains static, and then obtains an acceleration and upwards left, progressively accelerates, simultaneously acceleration upwards left.Then the acceleration change read with horizontal direction in the vertical direction of action induction chip is respectively as Fig. 2 and Fig. 3.
The change sequence of acceleration, according to the custom of waving of people, and itself the bodily form, strength etc. have clear and definite feature, may be used for the identification of action, thus avoid wrong report as much as possible.
Two, automatic decision signal is sought help.
Cell phone system can by the feature of acceleration action induction chip, and regarding as some reading may be dangerous signal, automatically sends an SOS.The foundation judged is acceleration acute variation, and the situation of this acceleration acute variation is probably fall or clash into generation.
As shown in Figure 4, in one embodiment, user falls from eminence, and its acceleration change feature is as follows: a downward acceleration, become suddenly an acceleration upwards, and time intensity is greater than 10g, then system thinks that this user may encounter trouble.At this time mobile phone can send help signal automatically.
As shown in Figure 5, in another embodiment, when user walks the Line, suddenly by car hit once, its acceleration change feature is as follows: be originally in low acceleration condition, the acceleration of unexpected appearance more than an intensity 20g, then system thinks that user has probably been hit, or hits wall by bike.At this time mobile phone can send help signal equally automatically.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
