Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In the embodiment of the present invention, detect the position that user is current, when the position that user is current is identical with the positional information of the traffic lights of pre-stored, detect user whether to be kept in motion, if user is kept in motion, then detect the wavelength of traffic lights, then the based reminding method corresponding according to the wavelength chooses of the traffic lights detected.
In order to technical solutions according to the invention are described, be described below by specific embodiment.
embodiment one:
Fig. 1 shows the process flow diagram of the based reminding method of a kind of traffic lights that first embodiment of the invention provides, and details are as follows:
Step S11, detects the position that user is current;
In this step, detect the current position of user by GPS localization method or wifi localization method.
Whether step S12, when the position that user is current is identical with the positional information of the traffic lights of pre-stored, detects user and be kept in motion;
In this step, prestore the positional information of each traffic lights in city, simultaneously, in order to improve the accuracy of the prompting of traffic lights, also need in real time or timing (as every other day or a week etc.) upgrade the positional information of the traffic lights stored, with timely by the updating location information of traffic lights to last state.
Alternatively, whether described detection user is kept in motion, and specifically comprises:
The acceleration of A1, detection user.Particularly, the acceleration of user is detected by acceleration transducer.
A2, when the acceleration of user exceeds default acceleration rate threshold, judge user be kept in motion, otherwise, judge user be in non-athletic state.Because user is different at the acceleration that stationary state and motion state are corresponding, therefore, by the acceleration comparing detection and the acceleration rate threshold preset to judge whether user is kept in motion.
Further, in order to improve the accuracy of user movement condition adjudgement, when detecting the acceleration of user, the angular velocity of user can be detected by gyroscope, like this, when the acceleration of user exceeds default acceleration rate threshold, continue to judge whether the angular velocity of user exceeds default angular velocity threshold value, and when the angular velocity of user exceeds default angular velocity threshold value, judge that user is kept in motion, otherwise, judge that user is in non-athletic state.
Step S13, when user is kept in motion, detects the wavelength of traffic lights.
Because user during transfixion, usually can not exist life security near traffic lights, therefore, when judging that user is kept in motion, just can be saved the resource of system by the wavelength of Tansducer For Color Distiguishing detection traffic lights.
When the position that user is current exists multiple traffic lights (the multiple traffic lights on such as multiple crossing), in order to improve the accuracy of testing result, the wavelength of described detection traffic lights, specifically comprises:

Certainly, if the wavelength of traffic lights do not detected in step S13, such as, any one wavelength of ruddiness, green glow, gold-tinted do not detected, then point out user by modes such as luminous and/or sounding.Such as, when Tansducer For Color Distiguishing is blocked by clothes, then on the screen of wearable device, send light source, such as flasher, or, sounded by loudspeaker, to point out user " work of Tansducer For Color Distiguishing is obstructed ".
Step S14, the based reminding method corresponding according to the wavelength chooses of the traffic lights detected.
In this step, when the wavelength of traffic lights detected be ruddiness represent wavelength time, select the based reminding method reminding user corresponding with red light; In like manner, when the wavelength of traffic lights detected be green glow (or amber light) represent wavelength time, select the based reminding method reminding user corresponding with green light (or amber light).
Alternatively, the described based reminding method corresponding according to the wavelength chooses of traffic lights detected, specifically comprises:
D1, be when no through traffic in the information that the wavelength of traffic lights is corresponding, prompting user can not pass through.Such as, when red light represents that no through traffic, if the wavelength of traffic lights is the wavelength that red light is corresponding, the information that then wavelength of these traffic lights is corresponding is that no through traffic, now, the high-frequency vibration prompt user sent by motor, or being sounded by loudspeaker, no through traffic for prompting user.
C2, when the information that the wavelength of traffic lights is corresponding is P Passable, prompting user P Passable.Such as, when green light represents P Passable, if the wavelength of traffic lights is the wavelength that green light is corresponding, the information that then wavelength of these traffic lights is corresponding is P Passable, now, the low frequency vibration prompting user sent by motor, or, sounded by loudspeaker and point out user's P Passable.
In first embodiment of the invention, detect the position that user is current, when the position that user is current is identical with the positional information of the traffic lights of pre-stored, detect user whether to be kept in motion, if user is kept in motion, then detect the wavelength of traffic lights, then the based reminding method corresponding according to the wavelength chooses of the traffic lights detected.Due to the wavelength of traffic lights can be detected, and the based reminding method corresponding according to the wavelength chooses of the traffic lights detected, therefore, whether change just can reach prompting effect without the need to user's lamp that makes out traffic signals, thus add the security of user by road.
