Content can be the contents such as short message, mail.Above-mentioned positional information is generally user and shares information of current location etc., is easy to
The household of user is quickly found out user.It is of course also possible to instant positional information is shared in timing, when user is given first aid to movement by other people
Afterwards, the household of user still can be quickly found user.
It is in the present embodiment, above-mentioned to judge that whether the acoustic information is the step of the acoustic information produced by bus environment
Suddenly, including：
S21, judge that whether frequency of sound wave is in default frequency of sound wave threshold range in the acoustic information；
S22, if so, then judge human body in fortune bus environment in.
As described in above-mentioned step S21 and S22, public transport path is fixed, then by positional information and public transport routing information
Directly comparison is carried out, if positional information falls on public transport path, the condition that user is located on bus is judged
Meet；After bus starts, the sound frequency which sends is specified at one in interval, if the user while on bus, then eventually
In the acoustic information that end is collected, the frequency range that primary band should be sent for bus, when primary band falls into default frequency of sound wave
In threshold range, then may determine that another condition that user is located on bus meets.After above-mentioned two condition is met, then
Can be determined that user on bus.In other embodiments, typically can also judge whether the amplitude of the sound wave in primary band expires
Foot is required, if same satisfaction requires just eventually to judge user on bus.
In the present embodiment, if above-mentioned be, judge that human body includes in the step on bus：
S23, the translational speed of human body is judged whether more than default threshold value, if it is greater, then when judging human body in public affairs
On cross-channel footpath, and when judging that human body is in fortune bus environment, judge human body on bus.
As described in above-mentioned step S23, user on bus as bus is moved together, so its translational speed is remote
More than user's walking or the speed of running, then when the translational speed of human body is more than default threshold value, illustrate that user is sitting in friendship
On logical instrument, when judgement human body is on public transport path, and when judging that human body is in fortune bus environment, then can be determined that
Human body is on bus.It is, when meet three it is pre-conditioned after, can just judge human body on bus, judged result
Accuracy it is higher.
In the present embodiment, on above-mentioned bus, judge that the algorithm whether human body falls includes：
S301, the first rate travel for calculating human body in the vertical direction, when first rate travel is more than default
Judge during first threshold that human body is fallen.
As described in above-mentioned step S301, user by bus when, be usually seated on the seat, or stand in a certain position
Put, significantly will not move, especially the rate travel of in the vertical direction is substantially zeroed, then when human body is fallen, typically all
There is larger rate travel in meeting in the vertical direction, so the rate travel on vertical direction relatively accurately can reflect
Now whether human body falls.Above-mentioned default first threshold, generally one critical value, when the first rate travel less than this first
Threshold value, then illustrate that human body is not fallen, and during more than the first threshold, then illustrates that human body has been fallen.The setting of first threshold, can
Being the empirical value got through a large amount of simulated tests.
