Description of the invention: [Technical field to which the invention pertains] A type of vehicle warning system is a vehicle warning system, in particular, a vehicle warning system having the function of a trailing and trailing vehicle. [Prior Art] When driving on a highway, it is often found that a large vehicle does not maintain a safe distance, and is closely behind the small car. The purpose is to force the small car in front to open the driveway. If the driveway is not congested, the small car can be replaced by the second one. The lane is to reduce the pressure of the rear vehicle too close, but when the road vehicle is congested, but the rear vehicle is close to the rear, it is forced to change lanes under this pressure, or must pay attention to the rear vehicle. The entire driving safety is a considerable threat. At present, most of the active safety warning systems of vehicles are based on the situation in front of the car as the development spindle. The radar is installed in front of the front of the vehicle to measure the distance between the vehicle and the preceding vehicle. When the distance between the vehicle and the preceding vehicle is too small, or the speed is too close. When the time is fast, the system will issue a warning. If the system determines that there is a danger of collision, the system will automatically calculate and pass the brake assist system to get the best brake assisting force, so that even if the brake pedal is pressed, Insufficient circumstances can also complement the braking force required to avoid collisions, but the design still does not fully meet the driver's safety protection. Therefore, in recent years, systems for post-vehicle safety protection have been developed and valued. The most popular use is the reversing radar system. In the case of low-speed reversing, it can be judged with the radar and other distance measuring devices, and the rear 201117981: The distance from T 'if the car is too close, then the alarm will be issued. It can be used at low speeds and is restored. μ, but this design is only for this device. If this system is used, the second warning will be issued to the driver when the vehicle is too close to the driver. 'The only way to put pressure on the driver is to threaten the driving safety of the driver. U-s alarm shows that the car is more =: does not maintain a safe distance and deliberately follow. The danger of the car, it is an urgent problem to be solved. SUMMARY OF THE INVENTION The problem of the present invention is to provide a vehicle warning system, including a vehicle distance measuring device and an image capturing device, in the present invention. , a processing component, a text identification: 7 display: shocked. The distance measurement device is used to measure the trailing vehicle distance ^ distance measuring device # is set with - (four) value, when the trailing vehicle distance = 槛 value, the material measuring device sends out the "distance signal, the image manipulation device is the license plate of the rear vehicle. The number and an image message containing the image of the licensee number. After the processing component receives the distance signal, the image processing device performs (4), and receives the image message sent by the device. The text recognition unit can recognize the text in the image message, and converts the image message into a package by using 4 201117981. The display device displays the image signal identified by the text recognition unit, including the warning signal warning signal of the license plate number and the text. The display device is a variable information display

Off, the warning system ‘When the trailing vehicle does not maintain the safety distance of the license plate: the display device of the second-ΪΪ方 will actively display the rear vehicle to the string’ to remind the rear vehicle to maintain a safe distance and achieve driving safety for the driver. The function of the μ king distance is to ensure that, as described above, the vehicle warning according to the present invention or a plurality of the following advantages: 八八八有(1) The vehicle is not in the system, by the initiative to show the full: from the trailing vehicle, Propose the scent containing its license plate number = Keep a safe distance from the vehicle behind the awake, and achieve financial efficiency ^ Must maintain the safety distance to ensure safe driving. The vehicle display system can be used to ban the evidence of non-compliance with the safety rules after being photographed by the image capture device. /Pushing accidents' This image message can be used as an accident judgment. [Embodiment] A vehicle warning system is shown. An image capturing device 2, please refer to Fig. 1, which is intended for the present invention. The figure includes a distance measuring device 1 201117981: display, for example, a text recognition unit 4 measuring device, quantity-tailing vehicle distance, 2^ set a safe distance test, when the trailing handle Μ " This threshold value gives a distance signal. j 褒 1 1 system, processing 7L parts 5 series receiving distance signal, and start the shadow 1 =:: two image removal device 2 recording meets the threshold value: with the message 4 =:; and:: one contains the license plate _ The image of this image is provided to the text; Identify; After receiving the f-image message, 'Yuan 4 Identification = Early Warning 70 4' by the text identification list for the scoop person 1 second notice ~ the license plate number, and this Image message conversion == vehicle license plate _ and text message: word----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- (4) Set 1 to be a ccd, c_s, surface digital camera or digital image capture device. Area:: Display: f is set to the rear of the vehicle and the display panel visible to the trailing vehicle, LCD Firefly: if: Display' includes one or a combination of LED daylight arrays. Example = Institute: 2: The first-real distance measurement of the vehicle warning system. The license plate number of the vehicle is "Μ·7777", and the threshold value of the vehicle, and the door is set to A, "AA_7777" and 201117981. The distance of QQ-8888 is A. When the distance A of the "AA-7777" vehicle and the distance measuring device of the "QQ-8888" vehicle meets the preset threshold a, the vehicle number is generated via the system. The warning signal of AA_7777 is displayed on the display device 3. The warning signal can be: "aa_7777 Please keep the distance of Wenwang" to achieve the purpose of warning that the trailing vehicle must maintain a safe distance and ensure driving safety. The above is intended to be illustrative only and not limiting. Any changes or modifications to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
