Description
Technical field:
The present invention relates to technical field of mobile terminals, relate to a kind of barrier infrared alarming cell phone of meeting, employing infrared sensing
Device measures the distance of mobile phone peripheral obstacle to warn user surrounding road condition, it is to avoid the generation of accident.
Background technology:
Along with mobile phone is integrated, technicalization and intelligentized development, cell-phone function extends from traditional voice SMS
The every aspect lived to video calling now, voice-enabled chat, guidance, shopping of making a reservation etc., people
Life be unable to do without mobile phone, no matter wait for bus, by bus, queue up handle affairs or have a meal shopping, brush hands of bowing
Machine has become as the one way of life custom of youngster, old people even child, thus causes mobile phone " race of bowing "
Troop grows stronger day by day.When bowing busy brush mobile phone, people often have ignored surrounding danger thus cause the accident
Frequently occur.Someone discloses on the net: just come off duty, and downstairs just taking out mobile phone sees cross-talk, bumps against building while walking
The awning that lower guard stands guard, Chu Liao work unit gate, knock again the awning of roadside stands, walked along roadside
, encountered again on the big tree in roadside！What is more, goes across the road, crosses crossroad and also bow and brush mobile phone.
In order to improve the intellectuality of mobile phone, existing mobile phone has installed acceleration, magnetic force, direction, gyroscope, light
10 multiple sensors such as line sensing, pressure, temperature, distance, gravity, linear acceleration, rotating vector,
Wherein, range sensor is made up of an infrared LED lamp and infra-red radiation light detectors.Range sensor position
Near the receiver of mobile phone, mobile phone is when ear, by range sensor, system knows that user is taking on the telephone,
Then can close display screen, prevent user because of maloperation impact call.Its operation principle is, infrared LED lamp is sent out
After the invisible infrared light gone out is by neighbouring object reflection, detected by infra-red radiation light detectors.But
The most also do not occur using infrared analysis cellie and about between the barrier such as people, car, tree away from
From to send the mobile phone of warning.Chinese patent CN201410111665X is blocked by infrared distance sensor perception
Thing moving direction realizes picture and map auto zoom, when shelter moves closer to embedded mobile device,
Distance is more and more less, and picture and map gradually amplify, otherwise, picture and map are gradually reduced.Infrared distance
Sensor has a lot of application in terms of range finding, but the mobile phone of integrated infrared distance sensor does not the most also occur
In order to remind user to note, surrounding is dangerous.
