Radar type obstruction warning mobile phone

Abstract

The invention discloses a radar obstruction warning handset, the handset comprises a handset casing, a central processor, a keyboard, a display part, a tone frequency output part, and a power supply part. The handset is characterized in that the handset also comprises an ultrasonic controller and an ultrasonic ranging sensor; wherein, the ultrasonic controller is respectively connected with the central processor and the ultrasonic ranging sensor, and is used to trigger and control the sensor ultrasonic detection; the ultrasonic ranging sensor has an ultrasonic probe, the probe sends ultrasonic to a measuring-awaited obstruction, the ranging sensor sends a received echo signal to the central processor through analog-digital converting, and the display part displays the ranging.

Description

technical field [0001] The invention relates to mobile terminal technology, in particular to a radar-type obstacle alarm mobile phone. Background technique [0002] Radar technology is becoming more and more mature. In the past, it was mostly used in military detection and other security aspects. At present, it has achieved good results in the application of civilian products such as reversing radar. At present, urban construction is accelerating, and many road construction or illegal private construction of temporary obstacles, many people due to Accidents frequently occur due to blurred vision such as dark night and fog, and it is especially difficult for blind people to travel in complicated cities. Simultaneously present reversing radar owing to can only be fixedly placed in the fixed position of rear bumper, for some positions, as there is a blind spot in some positions of oblique rear and can not play accurate guiding effect.

[0002] Radar technology is becoming more and more mature. In the past, it was mostly used in military detection and other security aspects. At present, it has achieved good results in the application of civilian products such as reversing radar. At present, urban construction is accelerating, and many road construction or illegal private construction of temporary obstacles, many people due to Accidents frequently occur due to blurred vision such as dark night and fog, and it is especially difficult for blind people to travel in complicated cities.

At the same time, the current reversing radar can only be fixedly placed in the fixed position of the rear bumper. For some positions, such as some positions behind the oblique, there are blind spots and cannot play an accurate guiding role.
