Background technique

As we all know, when a car is reversing, it usually uses the rearview mirrors on the left and right sides of the car to assist reversing. However, the viewing angle presented by the rearview mirror is limited, so there are many blind spots in the field of view. In order to improve the existing reversing mode through the rear mirror, a reversing monitoring device has been developed on the market. Since the reversing monitoring devices at this stage are all wired installations, it is necessary for the user to construct and install them. It takes a lot of energy to hide the connecting lines, and it is easy to damage the beauty of the interior decoration of the car. Moreover, the reversing monitor is fixed outside the car and is easily damaged. However, the existing wired reversing monitoring device is used in the connection When a car or a large trailer is used, it is often necessary to separate the sub-car and the parent car to connect the car, so the take-up line must be removed again every time, which is often tens of meters long, causing troubles for users.

Convenience, increase the safety of the car when reversing.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a wireless reversing monitoring device is composed of an image capture host and an image control display processing device; the image capture host includes: a surveillance camera, a high-frequency It is composed of a transmitter and a controller, the controller is a controller capable of controlling and starting a surveillance camera and a high-frequency transmitter, and having the function of controlling the channel switching of the high-frequency transmitter; the image control display processing device includes: frequency receiver, video frequency amplification frequency hopping controller and display, the video frequency amplification frequency hopping controller not only has the function of controlling the activation of the high frequency receiver and controlling the channel switching of the high frequency receiver, but also various It is a controller for converting different image outputs between image signal sources, and for signal amplification and noise elimination for input images. When the vehicle is put into the reverse gear, when the reverse action is performed, after the reversing power signal enters the controller and the video frequency amplification frequency hopping controller, the power supply of the surveillance camera and the high-frequency transmitter will be activated, and the surveillance camera will shoot the image behind the vehicle and send the The image signal is transmitted to the high-frequency transmitter, and the high-frequency transmitter converts the image signal into radio waves and sends it out; then through the high-frequency receiver, the received radio waves are restored to reversing image signals, and sent to the video frequency amplification frequency hopping controller , through the video frequency amplification frequency hopping controller, the signal is transmitted to the display after filtering the interference clutter and amplifying the reversing image signal.

The beneficial effects of the utility model are: the wireless reversing monitoring device provided by the utility model group, the image capture host and the image control display processing device adopt wireless separate settings, compared with the prior art, the wired installation is used, and the user During construction and installation, it needs to consume more tedious fortifications, which is more convenient and practical. Furthermore, the user can be used as a receiving car when the reversing action is not performed, and other multimedia video image signal sources can be used as a signal amplifier, and has the dexterity of anti-theft and easy disassembly, which increases the speed of the car when reversing. time security and add value to the product.

Detailed ways

The utility model mainly provides a wireless reversing monitoring device, which is composed of an image capture host and an image control display processing device, wherein the image capture host, please refer to Figure 1, including: a surveillance camera 1, a high-frequency transmitter Components such as device 2 and controller 3 are formed; This controller 3 has control and starts surveillance camera 1 and controls and starts high-frequency transmitter 2, and has the channel switching function of controlling high-frequency transmitter 2; (this above-mentioned high-frequency transmitter 2 is an existing general-purpose wireless transmission system, and the surveillance camera 1 is also an existing general-purpose image photography system, whose principles and application methods are already known to those skilled in the art, so no further description is given); the image For the relevant circuit diagram of the capture host, please refer to Figure 5.

Please refer to shown in Fig. 2 again, wherein image control display processing device comprises: high-frequency receiver 4, video frequency amplification frequency hopping controller 5 and display 6 constitute, this video frequency amplification frequency hopping controller 5 has control start high frequency receiver 4 and control the high frequency receiver 4, in addition to the channel switching function, and perform different image output conversion among various image signal sources, and perform signal amplification and eliminate clutter on the input image, so as to provide a good image for the display Signal source; for the related circuit diagram of the image control display processing device, please refer to FIG. 6 .

As shown in Fig. 3, when the vehicle enters the reverse gear and performs the reverse action, after the reverse power supply signal enters the controller 3 and the video frequency amplification frequency hopping controller 5, the monitoring camera 1 and the high-frequency transmitter 2 are started. After the power is turned on, the surveillance camera 1 shoots images behind the vehicle, and transmits the image signals to the high-frequency transmitter 2, which converts the image signals into radio waves and sends them out. Then, through the high-frequency receiver 4, the received radio wave is restored to the reversing image signal, and transmitted to the video frequency amplification frequency hopping controller 5, after the signal is filtered out by the video frequency amplification frequency hopping controller 5 to filter out the interference clutter and amplify the reversing image signal , and then sent to the display 6, so that the driver can clearly see the image behind the car, so as to achieve the safety of assisting the car in reversing.

As shown in FIG. 4 , it is the working description of the video frequency amplification frequency hopping controller 5. The video frequency amplification frequency hopping controller 5 further includes a video filter amplification circuit 51 and a power signal control circuit 52. When the reversing action is not performed , can be used as other multimedia video and video signal sources on the car to be used as a signal amplifier, and when the reversing power signal of the reversing action enters, the high-frequency receiver 4 will be started immediately and the reversing video signal will be switched and processed. The reversing image is sent to the display 6.
