Abstract
The invention discloses an ultrasonic based smart phone barrier prompting system. The system comprises a smart phone, a micro universal device, an ultrasonic sensor, a compass, an accelerometer, a gyroscope and a GPS. The system has the following work steps: (1) after obtaining a posture of the smart phone via the compass, the smart phone controls the micro universal device to ensure that the ultrasonic sensor always points at a preset angle; (2) the smart phone obtains the advancing direction of the smart phone via the compass to control the micro universal device so as to enable the ultrasonic sensor to point to the advancing direction of the smart phone always; (3) the smart phone controls an emitter of the ultrasonic sensor to emit ultrasonic waves; and (4) the smart phone calculates the time from a current position to a barrier according to the speed provided by the accelerometer and the distance provided by the ultrasonic sensor, wherein within two seconds, a screen of the smart phone is forced to shut down and a warning sound is given out, and not within two seconds, a user is prompted by the screen and voice.

Technical field
The present invention relates to mobile phone technique field, it is specifically related to a kind of based on hyperacoustic smart mobile phone obstacle prompt system.
Background technology
See that the people of mobile phone is a lot of at present on foot, cause a lot of safe event, such as:
In October, 2013, when the Hubei girl business of 17 years old goes out to have a dinner party with companion, while walk roadside to play mobile phone, when through a bridge, one is foot-operated empty, falls in the river not having guardrail to protect, dies after ineffectual treatment.
Quoting reporting of Nippon Press net according to www.chinanews.com, about Japanese 8: 10 evening of October 16 2013 local time, a man is because being absorbed in and playing mobile phone, it does not have noticing that level crossing guardrail puts down, the electric car unfortunately come collides to death.
On December 17th, 2013, when Melbourne, AUS one is walked in river bank from the girl of TaiWan, China night, accidentally overboard because being too absorbed in social network, fortunately she is just saved by police soon.
In February, 2014, Shanghai Underground announces of that month one section of thrilling video display, and a woman, when taking Shanghai Underground, owing to indulging in very much mobile phone, falls down platform, and fortunately Timeliness coverage is had nothing to do.
Therefore, it is badly in need of a kind of energy detection, points out dangerous mobile phone for people to use.
Summary of the invention
Embodiments provide a kind of safety problem seeing mobile phone based on the solution of hyperacoustic smart mobile phone obstacle prompt system on foot.
An object of the present invention is, it is provided that the smart mobile phone of a kind of obstacle pointed out in anterior approach.
The present invention is achieved through the following technical solutions above-mentioned purpose
A kind of based on hyperacoustic smart mobile phone obstacle prompt system, comprise smart mobile phone, miniature universal head, ultrasonic transducer, compass, jerkmeter, gyrostat, GPS; Algorithm is as follows.
Step 1: smart mobile phone obtains the posture of smart mobile phone by gyrostat, controls miniature universal head, makes ultrasonic transducer point to a predetermined angle all the time.
Step 2: smart mobile phone obtains the working direction of smart mobile phone by compass, controls miniature universal head, makes ultrasonic transducer point to the working direction of smart mobile phone all the time.
Step 3: ultrasonic wave launched by smart mobile phone control ultrasonic transducer projector, timing is started while launching, obstacle is encountered on ultrasonic wave way and is reflected back smart mobile phone, ultrasonic wave receptor receives reflection wave and just stops timing immediately, and smart mobile phone calculates the distance of obstacle by timing time, when described distance is identical with a upper moment, there is no obstacle above, when distance exceedes nominal error, before have obstacle, smart mobile phone is by screen and voice message user.
Step 4: the speed that smart mobile phone provides according to jerkmeter and the distance that ultrasonic transducer provides, calculate the time of obstacle, if in two seconds, mobile phone is then forced to close screen, give a warning voice, if outside two seconds, then by screen and voice message user.
Smart mobile phone is equipped with miniature universal head, for placing ultrasonic transducer, and accurately control ultrasonic transducer transmit direction; Corresponding with the universal head respectively spindle in ultrasonic transducer both sides is connected.
The type of obstacle has road depression, hangs thing, projection, step, metope, pedestrian.
The useful effect of the inventive method is: provide a kind of safety problem seeing mobile phone based on the solution of hyperacoustic smart mobile phone obstacle prompt system on foot.
