Vehicle approaching reminding device and method

Abstract

The invention relates to a vehicle approaching reminding device, which comprises an optical flow detection unit used for detecting external optical flow in real time and generating optical flow signals; a processor for obtaining moving speed of vehicles around a wearer and determining position according to the optical flow signals, obtaining the distance between the moving vehicle and the wearer and relative movement speed through data processing, and when the distance between the moving vehicle and the wearer and the relative movement speed surpass set values, generating a control signal; a vibration generation unit used for generating vibration according to the control signal; and a laser unit for generating laser beams according to the control signal. Compared with the prior art, the reminding device can be worn on a human body, helps people to improve perception of danger that the moving vehicle is approaching, and meanwhile, can remind drivers to take corresponding measures, thereby avoiding accidents and improving safety.

Description

technical field [0001] The invention relates to the field of wearable technology, in particular to a device and method for detecting the approaching speed and current distance of a vehicle and sending out a reminder signal. Background technique [0002] With the development of social technology, there are more and more novelties, especially in big cities, where advertisements are everywhere, no matter adults or children, walking on the road or activities on public roads, it is easy to be All kinds of things attract attention, so that they can't notice the threat to their safety from the driving vehicles outside their line of sight, especially children, when walking on the road, they tend to be fully focused by the things in front of them , Can’t notice whether the car coming from behind will collide with it. At this time, if the driver of the vehicle driving behind is not focused enough or responds quickly enough, it is easy to cause an accident. [0003] At the same time, ...

[0002] With the development of social technology, there are more and more novelties, especially in big cities, where advertisements are everywhere, no matter adults or children, walking on the road or activities on public roads, it is easy to be All kinds of things attract attention, so that they can't notice the threat to their safety from the driving vehicles outside their line of sight, especially children, when walking on the road, they tend to be fully focused by the things in front of them , not paying attention to whether the car coming from behind will collide with it. At this time, if the driver of the vehicle driving behind is not focused enough or responds quickly enough, it is easy to cause an accident

[0003] At the same time, due to the small range of sight in the driver's cab, or the driver of the vehicle does not concentrate on driving the vehicle, drivers who drive normally cannot see or clearly see the children playing on the road. Only when it is close, it is often too late to brake the vehicle, which leads to tragedy
