The detectable signal of the application is preferably wifi signal, in the communications field, RTT (Round Trip Time, when round-trip Between) it is signal from being sent to the time for receiving response and spending.This time mainly includes signal between two communication terminals Propagation spend time.For wireless signal, it is whole in two communications that this time is equivalent to light (i.e. any signal) Hold the time spent.The application is based on WiFi RTT technology；Its data frame has:Each unicast packet side of being received immediately The intrinsic characteristic of confirmation, therefore it is suitble to detection range.When WiFi data frame is propagated, the total time that signal propagates cost is： Start to transmit data packet and receive the duration between corresponding data, which is known as long-range delay (dremote)；Receiving end receives It after to signal and sends reply data and has a delay, which is known as local delay (dlocal)；Therefore data frame is total Be with the propagation time in distance：Long-range delay subtracts the time locally postponed.So utilize the public affairs of WiFi signal ranging Formula is：
(c≈3*108M/s, that is, the light velocity)；Because of the wave band one of electromagnetic signal and light It causes, therefore spread speed is also 3*108m/s；Transmitting terminal and the distance between be distance, therefore signal from be sent to receive Response has propagated twice of distance, i.e. 2*distance；Dremote is to propagate the total time spent, and dlocal is in receiving end On delay, so the time spent in distance is the difference subtracted each other of two times.
The application is based on above-mentioned basic principle, by being sent out the relative distance of detectable signal and danger source, Jin Erti Before predict Encounter Time between terminal and danger source, and give user to issue early warning in advance before Encounter Time arrival, Ensure that user security, and on the other hand, the source of being safe from danger close to when illustrate user's temporarily relatively safety；Above-mentioned side When detecting user's using terminal, directly limitation user does not use case, but by the detection of danger source and gives warning in advance Mode, both can guarantee unlimited user's using terminal processed, and can guarantee user security.
As a kind of optional embodiment, the method for obtaining triggering command includes：
Obtain the geographical location information that terminal is currently located；
Judge terminal currently whether in the predetermined area according to the geographical location information；
If terminal is currently at the predetermined area, triggering command is generated, and obtain；
By GPS positioning function obtain geographical location information, measure user close to traffic environment complexity area (such as The predetermined areas such as crossroad) when, active transmission detectable signal detects danger source, and is reminded in advance；In this way, when user is complete When immersing on mobile terminals entirely, the possible danger of user can be also reminded in time.
As a kind of optional embodiment, before generating triggering command, the method also includes：
Detect whether user is using the terminal,
Detecting that user when using the terminal, generates triggering command.
