Description

Active Detection Safety Warning System

A safety warning system, in particular an active detection safety warning system for reminding the driver of the vehicle.

According to the report, existing vehicle warning systems mainly use radar and cameras as sensing elements, including Collision Warning with Full Auto Brake (CWFAB), Automatic Collision Avoidance System (ACAS), Blind Spot Information System (BSIS) and Lane Keeping Assist System (LKAS). According to statistics from the Ministry of the Interior's National Police Agency, the causes of death on the spot or within 24 hours due to traffic accidents include 14 categories, including illegal overtaking, driving in the wrong direction, speeding and loss of control, and failure to turn according to regulations. As much as one-third of the deaths are caused by failure to pay attention to specific road conditions, such as driving on roads with reduced average speed, obstacles, bumps, dangerous downhill slopes, and frequent acceleration and deceleration, which can affect normal driving behavior and events. This shows the importance of warnings for specific road conditions to driving safety.

When large vehicles are turning, especially when turning right, there is a blind spot on the side of the vehicle. If pedestrians or motorcyclists are not careful, serious accidents may occur, and deaths or serious injuries often occur.

Therefore, how to solve the above problems and deficiencies of the existing technology is an urgent research topic for relevant industries.

The invention provides an active detection safety warning system, which is particularly used to be installed in a car. The active detection safety warning system includes at least one light projection device, at least one image capture device, a database, a central control processor and a warning device.

The following is a detailed description through specific embodiments, which will make it easier to understand the purpose, technical content, features and effects of this invention.

After years of research and development, the creator has improved the shortcomings of existing products. In the following, we will introduce in detail how this creation achieves the most efficient functional requirements with an active detection safety warning system.

Various exemplary embodiments will be more fully described below with reference to the accompanying drawings, and some exemplary embodiments are shown in the accompanying drawings. However, the concepts of the present invention may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments described herein. Rather, these exemplary embodiments are provided so that the present invention will be detailed and complete and will fully convey the scope of the present invention concepts to those skilled in the art. In the drawings, the size of the top view and the side view and the relative size may be exaggerated for clarity. Similar numbers always indicate similar elements.

It should be understood that although the terms first, second, third, left outer side (or left side), right outer side (or right side), bottom, one end, tail end, etc. may be used in this article to describe various elements and their relative positions, these elements should not be limited by these terms, and the first, second, and third do not have a certain numerical order relationship. These terms are used to clearly distinguish one element from another. Therefore, the first device discussed below can be called the second device without deviating from the concept of this creation; and the left outer side (or left side) can be called the right outer side (or right side) without deviating from the teaching of the concept of this creation. As used herein, the term "and/or" includes any one of the associated listed items and all combinations of one or more. Furthermore, the term "at least one" may be used herein to describe a device having one or more (two, three, four) components, but such at least one device is not limited to implementing the technology implemented by one, two, three or four or more components.

Please refer to the first to third figures. The first figure is a schematic diagram of the system architecture of the active detection safety warning system of the present invention. The second figure is a schematic diagram of the first embodiment of the active detection safety warning system of the present invention. The third figure is another schematic diagram of the first embodiment of the active detection safety warning system of the present invention. As shown in the figure, the active detection safety warning system 100 of the present invention is particularly used to be installed on a vehicle TK. The active detection safety warning system 100 includes at least one light projection device 110, at least one image capture device 120, a database 130, a central control processor 140 and a warning device 150. At least one light projection device 110 is used to project a preset pattern PD on the ground, wherein the preset pattern PD is a polygon and is composed of a plurality of grids NT, wherein the preset pattern PD is used to remind passers-by or other vehicle drivers. In addition, a plurality of light projection devices 110 can be respectively installed on the left side, right side, front side and rear side of the car to respectively project the corresponding preset patterns PD on the ground, as shown in the second figure. At least one image capture device 120 is used to continuously and actively detect a warning area of the preset pattern PD on the ground, and capture a plurality of images to be judged BD. In addition, multiple image capture devices 120 can be installed on the left, right, front and rear of the car respectively to continuously and actively detect a warning area of the preset pattern PD on the ground. The image capture device 120 can be, for example, a camera or a monitor.

In addition, the database 130 stores an original image AD of the preset pattern PD. If it is a different preset pattern PD, it will correspond to a different original image AD. In addition, the database 130 can be connected to the Internet through the Internet device on the car or the relevant Wifi to update the database. The central control processor 140 is connected to the light projection device 110, the image capture device 120 and the database 130. The central control processor 140 is used to receive multiple images to be judged BD transmitted by each image capture device 120 and judge whether each image to be judged BD is the same as the corresponding original image AD. If they are not the same, an alarm signal AL will be generated. The warning device 150 is connected to the central control processor 140. After receiving the warning signal AL, the warning device 150 will emit an alarm sound TA or a warning voice TB to remind the driver of the car TK.

Furthermore, the central control processor 140 compares the grid NT of each image to be judged BD with the grid NT of the original image AD to determine whether part of the grid NT of each image to be judged BD disappears. If part of the grid NT disappears, the warning signal AL is generated. If part of the grid NT does not disappear, the next one is compared and judged continuously. In other words, if a person or an obstacle is located in the warning area, a part of the grid NT of the image to be judged BD will be covered, and vice versa, if a part of the grid NT of the image to be judged BD is covered, it means that a person or an obstacle is located in the warning area. Furthermore, the default pattern PD is a pattern of grid lines, or in another implementation, the default pattern PD is a pattern of grid lines and text. As shown in the second figure, the preset pattern PD correspondingly projected by each light projection device 110 is located in a different area, which is located around the car TK. Through the working mechanism of the active detection safety warning system 100 described above, as shown in the third figure, when a person, a car or an obstacle appears in the area formed by the preset pattern PD, the warning device 150 will remind the driver of the car TK. The car TK in the second and third embodiments is a truck or a van.

In addition, please refer to the first and fourth figures. The fourth figure is a schematic diagram of the second embodiment of the active detection safety warning system of the present invention. The active detection safety warning system 100 of the present invention can be installed not only on a truck or a van, but also on a general automobile, such as a motorhome, a sedan or a SUV, as shown in the fourth figure. Therefore, the active detection safety warning system 100 of the present invention is not limited to the type of vehicle to which it can be installed.

It is worth mentioning that please refer to the first, second and fifth figures at the same time. The fifth figure is a schematic diagram of the active detection safety warning system of the present invention after adjusting the projection angle. In one embodiment, the central control processor 140 adjusts the projection angle of the light projection devices 110 according to the speed of the car TK, and the corresponding relationship between the speed of the car TK and the projection angle can be designed according to actual needs. In this way, when the car TK is stationary, the light projection device 110 projects a preset pattern PD on the ground closer to the car TK. When the car TK has a certain speed (for example, 60 kilometers per hour), the light projection device 110 projects a preset pattern PD on the ground farther away from the car TK, so that other vehicles behind can see the projected warning within a safe driving distance.

In summary, the active detection safety warning system disclosed in this invention can bring the following effects: 1. Visual projection warning to remind other pedestrians or vehicle drivers in real time; 2. Active warning to vehicle drivers to achieve protective effect; and 3. Easy to install and low cost, and effectively reduce accidents.

However, the above is only the best embodiment of this creation, and is not used to limit the scope of implementation of this creation. Therefore, all equivalent changes or modifications based on the characteristics and spirit described in the application scope of this creation should be included in the application scope of the patent for this creation.
