As shown in Figure 1, pedestrian's alarming device comprises distance detecting sensor 101, walkaway sensor 102, controller 103 and loud speaker 104 according to an embodiment of the invention.
Distance detecting sensor 101 is for detecting the distance with pedestrian.The distance with pedestrian can be detected in several ways.Such as, the scope of body temperature is generally 36 DEG C-37.5 DEG C, and people knows from experience the certain infrared ray of release.Distance detecting sensor 101 can be infrared inductor, for sensing the infrared ray that human body sends, and the such as infrared ray of about 10 μm.In another example, distance detecting sensor 101 can also comprise camera, to identify the pedestrian in captured image.Distance detecting sensor 101 can to human body generation electromagnetic wave or sound wave etc., and detects from the echo of human body reflection to determine the distance with pedestrian.
Walkaway sensor 102 for detection background noise with formation background noise signal.Such as, described walkaway sensor 102 is microphones.
Controller 103 is for forming prompt tone signal based on described ambient noise signal.
Loud speaker 104 is for playing sound based on described prompt tone signal.
In the present invention, controller 103 can also be used for control noises detecting sensor 102 relative at least one in the position of loud speaker 104 and direction, to make when the distance with pedestrian is less than preset distance, described walkaway sensor 102 is positioned at the radiation of sound region of described loud speaker 104, thus formation is uttered long and high-pitched sounds.
Such as, the detection range of distance detecting sensor 101 can be set to 10m.When pedestrian just being detected, can judge that the distance of vehicle and pedestrian is 10m, harmful grade is lower.Now, controller 103 can control, and to make the distance between walkaway sensor 102 and loud speaker 104 comparatively large, and walkaway sensor 102 is positioned at outside the radiation of sound district of loud speaker 104, avoids loop to utter long and high-pitched sounds.Such as, loud speaker 104 also comprises power amplifier, for receiving the prompt tone signal of self-controller to play.
