Description

Vehicle Imaging Warning Device

technical field

The invention relates to the field of warning devices for vehicles, in particular to an imaging warning device for vehicles.

Background technique

When a vehicle breaks down and needs to be parked by the side of the road, usually the driver will place a warning sign 50-100 meters behind the vehicle. meters or more.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in Figures 1-3, a vehicle imaging warning device includes a CPU controller (1), a radar distance measuring device (2), and an imaging warning device installed on the vehicle. The device (3), the voice control device (4) and the power supply (5), the radar ranging device, the imaging device, the voice control device and the power supply are respectively electrically connected to the CPU controller. Wherein, the radar distance measuring device (2) is a laser radar range finder; the imaging device (3) is an aerial three-dimensional imager or a two-dimensional imager; The audio module electrically connected to the audio module and the speaker electrically connected to the audio module are composed of two parts; the power supply (5) is a power supply module electrically connected to the vehicle battery; the imaging lens (6) of the imaging device (3) is located at The center of the rear surface of the vehicle chassis; the ranging probe (7) of the radar ranging device (2) is located on the rear surface of the vehicle chassis; the loudspeaker of the voice control device (4) is built into the rear surface of the vehicle; the A WIFI module is connected to the CPU controller (1).

The feature of the present invention is to provide an imaging warning device to replace the warning device of the existing warning sign. Through the aerial imaging technology, an obvious warning image and text prompts are formed in the air or on the ground at a certain distance from the rear of the vehicle to remind the vehicles coming from behind. distance. When the user uses the warning device of the present invention, if the vehicle behind continues to move forward, the warning image will move accordingly, and will always be located in front of the visible position of the vehicle behind, and the distance change will be reminded by text. When the rear vehicle approaches the distance set by the faulty vehicle, the vehicle alarm sound device sounds very sharply to remind the rear vehicle. When the device is in use, it can be connected with external devices through the WIFI function to change the information to be displayed and the alarm sound.

In this technical solution, the radar ranging device is connected to the CPU controller for measuring the real-time distance between the vehicle and the rear vehicle, and the power supply is used to provide the CPU controller, imaging device, voice control device, and the radar ranging device. The working power supply, the voice control device and the imaging device are connected to the CPU controller, and the CPU control device is also connected with a WIFI module, which has a WIFI receiving function, and can be wirelessly connected with external devices through WIFI, and the image can be edited through WIFI The reminding text information displayed by the device is used to warn the vehicles coming from behind.

In this technical solution, as shown in Figures 2 and 3, when a vehicle breaks down on the road, park the vehicle on the side of the road, wait for inspection and repair, and turn on the button of the hazard warning light, then the vehicle coming from behind will see The corresponding warning text information can effectively avoid the possibility of secondary accidents. When the button of the hazard warning light is turned on, the power supply of the vehicle imaging warning device is also connected, and each component starts to work. First, the radar ranging device will send the distance from the vehicle behind to the faulty vehicle to the CPU controller. When the rear vehicle is 300m away from the faulty vehicle, the CPU controller will process the corresponding data and pass the imaging device at the distance from the faulty vehicle. A warning text is formed at 300m from the rear of the car. When the car coming from behind continues to approach, the radar distance measuring device will also provide corresponding data to the CPU controller, and the CPU controller will pass the corresponding information through the imaging device on the car of the faulty vehicle. The tail is continuously displayed while remaining within the forward visibility of vehicles behind. When the vehicle coming from behind is close to the alarm position set by the faulty vehicle for 100m, the CPU controller will transmit the corresponding data to the voice control device, and the voice control device can remind the rear of the dangerous information in the form of sound, so as to realize the warning function to the rear vehicles , the vehicle behind can take braking measures to avoid colliding with the vehicle in front. Wherein, both the imaging device and the voice control device can be connected to external devices through WIFI to pre-set the display and sound warning information of the imaging device.

The above-mentioned technical solution only embodies the preferred technical solution of the technical solution of the present invention, especially setting an aerial imaging device at the rear of the car to realize the aerial imaging warning function is the core solution of this technology. Some changes that may be made reflect the principles of the present invention and fall within the protection scope of the present invention.
