This hot green reversing radar can provide a driver's sight dead angle image and the distance between the vehicle and the obstacle at night. Radar device. [Previous technology] 2 Vehicle materials are installed with reversing materials, read and measure the distance between the driving or reversing disk 'dagger handles or obstacles, and make a sound when they are too close to remind the driver to increase the vehicle Its safe. = At present, most reversing radars only cooperate with the detection of the ultrasonic detector king, and then control the sound of the siren, and cannot check the actual road conditions. In fact, the 'reversing radar is installed to assist the driver out of sight, provided: -A kind of radon facility for safe distance detection. However, because the back-up Darley does not indicate the actual situation of the obstacles encountered by the driver, when the lower movable obstacles are approaching, although the obstacles are known to be on the travel path, they still cannot dodge immediately. In response to the aforementioned problems, there are currently improved back-up radar devices that provide an additional image capture and playback function. The back-up radar is installed in the rear-view mirror of the driver's seat or a separate display. The image captured by the pick-up is played on the rearview mirror or display in the car, which can provide the driver's situation at the rear of the car to reduce the blind angle of the driver's sight. Huai, the reversing radar device with this image playback function is currently only used in small cars, and is only equipped with an image capture device. Therefore, when such a parking sensor is applied to a large vehicle, as the large vehicle has a smaller vehicle width, the relative sight is dead. 1232820 The attached image capture device is obviously insufficient. However, if it is only to expand a plurality of image capture devices, there will be many technical problems, that is, 1 · Wired parking sensor ·· If this type of parking radar device simply adds image capture devices It will be clear that there are wiring difficulties, and for a display that is only played by one set of image capture devices, it will not be able to support the display of multiple video images of multiple image capture devices. , 2 · Wireless parking sensor · == Complicated wiring, but multiple image extractors: = roads and will interfere with each other 'In addition, parking sensors with the same intentions are installed separately. Will cause the signal is not simply increase ... So, based on the various technical problems mentioned above can be solved by adding a plurality of image pickers. [Summary of the Invention] The main purpose of this month is to provide a wireless reversing radar device 4 that can display multiple images of the shoulder blades, namely, handle, θ u γ stem, and video. The video is provided by the driver for multiple drivers, and the number 6 is more than 70. In cooperation with the playback of the video, the driver can understand the situation where the vehicle is out of sight and ensure the safety of driving. The main technical method used by the thundered officer is to make the wireless reversing. The package g has a wireless transmission processing unit and a helmet ππ image capture device; and a plurality of image capture devices are set at the position of the blind spot of the line of sight generated by the vehicle. The line transmission processing unit is mainly controlled by a central control unit. It consists of a sound wave processor and a helmet-backed smoke-shooting unit. The central control unit is 1232820: The detection signal of the wave detection benefit is processed and output to the wireless core unit for transmission to the wireless reception processing unit. The wireless receiver is connected to a complex image manipulator to capture different locations around the car: Image: superimpose the signal detected by the ultrasonic detector with the complex image signal-after compression The system_outputs from_video channels to display the cry so that the display can simultaneously display multiple overlapping image signals on the same daytime surface. The figure is refined, and the present invention provides a driver ’s vehicle sight around the dead angle. , And cooperate with the distance data from obstacles, greatly reduce vehicle driving, collisions when backing up due to out-of-sight, thereby improving travel and protection. [Embodiment] The present invention is a type that can be used for large vehicles Installed wireless transmission type reversing device: It can be equipped with a plurality of image capture devices, and the plurality of image capture devices and ultrasonic detectors can be installed at positions where large blind spots are likely to occur in the vehicle. The image and the distance to the obstacle are provided for the driver to understand. First of all, please cooperate with the first picture, the reversing radar system mainly includes a wireless transmitting processing unit (10), a wireless receiving unit (0) and a plurality of image captures. Taker (50), of which: The wireless transmission processing unit (10) please cooperate with the second and third diagrams as shown in the figure below: '-Central control unit (ii), It is connected with a health storage unit (work 1 1) 'for storing the ID number of each ultrasonic detector; a plurality of ultrasonic detectors (2 0), and each ultrasonic detector (2 01232820) passes through a signal processing circuit (2 1) Connected to the input of the central control ...

The image and the reversing radar detection 1232820 1 distance are displayed on the display (60), as shown in the sixth figure, which is a miscellaneous-preferred embodiment, that is, three sets of image manipulators (50) and Three sets of ultrasonic detectors (20), and three sets of image extractors and (50) ultrasonic detectors (20) are installed on the left, right, and rear three of the rear compartment (7 workers). Position, so the display (60) on the day shows the images of different positions of the carriage together, and the distances between different positions and obstacles detected by each ultrasonic detector (20) are on the day. Function buttons are provided on the display (60). Yes, choose to play the image (picture) of a specific image capture device, or to play all the image capture images (day to day) 1-3. The indicator (60) is connected to the main controller (60). ㈣ The main technology is (3 1) The selected function command can be notified to the programmable logic processor (4 workers) through the main controller connection " face (4 3). The programmable logic processing (4 1) device can The electronic multiplexer (42) is controlled to sequentially switch or only the image output terminal of a specific image capture device (50) is connected to achieve the execution of the aforementioned functions. It can be known from the above that the reversing radar device of the present invention uses video graphics to superimpose a plurality of image capture devices and ultrasonic detectors, and the image capture state can be set at the position where the car body is prone to blind spots, so multiple images The image captured as the dead angle of the captured field of view can be integrated and played on a display. In addition, the video graphic text overlayer can also add graphics, text and video images together, so the daylight surface of the display It can also display the distance data between the vehicle body and the obstacle detected by the ultrasonic detector; in this way, those who drive the 1232820 can easily expand the field of vision of the vehicle through the display, and relatively reduce the probability of the vehicle body colliding with the early obstacle of I1, which is effective Improve driving safety.
