New description: [New technical field] - This new type is related to the type of reversing warning system, especially a reversing warning system that can display rear view images for viewing. [Prior Art] When a general car driver reverses, there will be some deaths behind the vehicle. It is difficult to observe. In order to improve the safety of the reversing, the driver will install it in the rear of the vehicle. (5) The radar is used to measure the rear obstacles. It is detected that when an object appears within a certain distance from the vehicle f, the system inside the vehicle is driven, and a warning sound is sounded to remind the driver that there is an object behind the vehicle. Although the above device can measure the distance between the object and the vehicle auxiliary room and achieve the warning effect, when the radar warning device is used, the driver cannot know the actual position and the moving state of the rear object by the warning sound alone. 'The above warning device cannot pick up and display the image behind the car, so it is still not ideal for use. [New content] Therefore, the purpose of the present invention is to provide a reverse warning system that can display a rear image. Therefore, the new reversing warning system is disposed on a car and includes a video processing unit, a central processing unit, a display unit, and a warning unit. The image capturing unit is disposed behind the car and takes a space image behind the car. The central processing unit is electrically connected to the image capturing unit, and receives and analyzes the image captured by the image capturing unit to determine the distance between the vehicle M316836 and the rear object. The display unit is electrically connected to the central processing unit and receives the video signal transmitted from the central processing unit to play the video. The warning unit is installed in the vehicle and electrically connected to the central processing unit. When the distance between the vehicle and the rear object is less than a safe distance, the warning unit is driven by the central processing unit to generate a warning signal. The image capturing unit captures the image and plays it out by the display unit, and analyzes the image signal through the central processing unit to determine the distance between the car and the rear object, which can simultaneously capture images and determine the safety of reversing The design of the distance is different from the previous innovation and can effectively improve the safety of reversing. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the detailed description of the preferred embodiments of the present invention. As shown in FIGS. 1 and 2, a preferred embodiment of the present reversing warning system is mounted on a car 1. In the present embodiment, the car 1 is an example of a car, but when implemented, the car + i It can also be a truck, electric vehicle or other kind of vehicle. The reversing warning system includes an image capturing unit 2, a central processing unit 3, a display unit 4, and a warning unit 5. The image capturing unit 2 of the present embodiment is a space image mounted in an installation space 11 of the rear body of the car and is behind the car 1 at a predetermined distance. A specific example is a camera. Of course, in actual implementation, the image capturing unit 2 can only capture the rear image, and does not need to be limited by the position on the vehicle body. " M316836 age processing unit 3 is disposed in the car 1, and is electrically connected to the image 7 for receiving and analyzing the distance captured by the image capturing unit 2 to capture the distance between the car i and the rear object: : After the signal is processed, it is synchronously transmitted to the display unit 4. And the Gu:: sister is also set in the car 1 and electrically connected to the central processing unit 3 'and receives the central processing unit 3 worthy of the "image signal from the early 70 3, and then will affect For the driver to view, the specific example of the display unit 4 is a liquid 曰曰 '., a member, an organic electroluminescent display, etc., but is not limited to the above-mentioned types. - The warning unit 5 is installed in the car 1, And the central processing unit is connected to the central processing unit 3 to generate a warning signal for the driver. In the embodiment, the unit 5 is a 2-port eight and can issue a warning sound, but In the implementation, no (four) mouth eight is a limit, for example, the light bulb can also be used to generate warning light. The new type of reversing police (four) system is to make (4), must be preset to the car] rearward rearward-segment distance is the safe distance for reversing. When the driver is in the process of reversing, (4) the unit 2 will take the image of the rear of the car with _, and the display will be played out for the driver to watch. At the same time, the central processing unit 3 will also Analyze image capture unit 2 at any time Take the image and judge the car! The distance from the rear object, as the method of judging the distance is the conventional technology, and it is not the improvement focus of this new type, so it will not be described in detail here. Once the central processing unit 3 judges the car i and When the distance of the rear object is less than the safety distance, it will immediately drive (4) the soil: the warning signal such as warning sound or lighting is issued by the element 5 to drive the vehicle; the rear object has entered the safety distance, and the driver should reverse the vehicle. Beware of the M316836. Because it is usually reversed, when a large object appears behind the driver, the driver can also observe it by the rear view mirror. However, sometimes there are small objects located at the rear corner of the car 1, such as a sudden passing small animal or setting. The small potted plant with a low height on the ground is not easy to observe. This is the image capturing unit 2 of the present invention, which can be used for a wide (four) head, or adjust the installation angle to pick up the rear of the car. The surrounding image is used to achieve a better reversing warning function. In summary, the image capturing unit 2 utilizes the method of capturing images. And the central processing unit 3 analyzes the image signal to determine the distance of the object behind the vehicle, and drives the warning I5 to issue a warning signal when the object enters a safe distance. This can simultaneously capture the rear image and determine the safe distance of the reverse. The design is actually-innovative and improved, and the driver can display the rear image at any time by the display unit 4 when reversing, and can help the driver understand the surrounding environment of the car + i, and effectively improve the safety of the reversing. The above is only the preferred embodiment of the present invention, and is not limited to the scope of the present invention, that is, the simple equivalent change of the patent in the present invention: the surrounding and the new description And the modifications are still within the scope of the present patent.
