[0026] Specifically, Figure 1 As shown, in this embodiment, the receiver mainboard 2 is connected to the video host 4, receives the analog signal output by the video host 4, and encodes it into a digital coded signal; the signal transmission mechanism is connected to the transmitter mainboard 1 and the receiver mainboard 2, and the signal transmission mechanism transmits the digital coded signal to the transmitter mainboard 1; the transmitter mainboard 1 is connected to the display module 3, and the transmitter mainboard 1 decodes the digital coded signal into an analog signal and outputs it to the display module 3, and the display module 3 is used to display the monitoring video; the video switching mechanism is connected to the transmitter mainboard 1 and the receiver mainboard 2, and the video switching mechanism receives the switching instruction issued by the transmitter mainboard 1 and sends it to the receiver mainboard 2, and the receiver mainboard 2 sends it to the video host 4 for video switching after receiving the switching instruction. The remote control transmits wireless signals, and the user can conveniently control and switch the monitoring video at different locations in the car without directly contacting the video host 4, which improves the convenience and flexibility of operation; the analog signal is encoded into a digital signal by the receiver mainboard 2 for transmission, which can reduce the interference and loss of the signal during the transmission process, and ensure the stability and clarity of the video signal. The transmitter mainboard 1 decodes the digital signal into an analog signal and outputs it to the display module 3, ensuring the quality of the video picture; the video switching mechanism can realize the rapid switching of different monitoring video sources. The switching instruction is sent through the transmitter mainboard 1, and the receiver mainboard 2 receives and transmits it to the video host 4, which can quickly respond to the user's switching needs and ensure the real-time and continuity of monitoring.

[0027] Further, if Figure 1As shown, in this embodiment, the signal transmission mechanism includes: an image transmission RF transmitting module 51, an image transmission RF receiving module 52, a first antenna 53 and a second antenna 54; the image transmission RF transmitting module 51 is connected to the receiver mainboard 2, and the first antenna 53 is connected to the image transmission RF transmitting module 51; the image transmission RF receiving module 52 is connected to the transmitter mainboard 1, and the second antenna 54 is connected to the image transmission RF receiving module 52; the image transmission RF transmitting module 51 receives the digital coded signal and sends it to the image transmission RF receiving module 52 through the first antenna 53 and the second antenna 54 in sequence; the image transmission RF receiving module 52 sends the digital coded signal to the transmitter mainboard 1. Using the image transmission RF transmitting and receiving modules to achieve wireless transmission reduces the need and complexity of wiring. Wireless transmission makes the system installation easier, especially suitable for limited space and mobile environments such as in-vehicle environments; RF transmission is more resistant to interference than traditional analog signal transmission, especially in a vehicle-mounted environment where electromagnetic interference may be more, and the use of RF transmission can reduce signal attenuation, ensure signal quality and transmission stability; it can increase the transmission distance and is easy to expand.

[0028] Further, if Figure 1 As shown, in this embodiment, the video switching mechanism includes: a digital transmission RF transmitting module 61, a digital transmission RF receiving module 62, a third antenna 63 and a fourth antenna 64; the digital transmission RF transmitting module 61 is connected to the transmitter mainboard 1, and the third antenna 63 is connected to the digital transmission RF transmitting module 61; the digital transmission RF receiving module 62 is connected to the receiver mainboard 2, and the fourth antenna 64 is connected to the digital transmission RF receiving module 62; the digital transmission RF transmitting module 61 receives the switching instruction, and sends it to the digital transmission RF receiving module 62 through the third antenna 63 and the fourth antenna 64 in turn; the digital transmission RF receiving module 62 sends the switching instruction to the receiver. Digital transmission RF transmission has an efficient transmission speed, which can realize fast and real-time instruction transmission, ensure the fast response speed of video switching, and improve user experience.

The digital signal is less interfered and attenuated during the transmission process, ensuring the stability and clarity of the signal quality. The digital signal has a high transmission efficiency and can support higher resolution and faster transmission speed, ensuring the clarity and smoothness of real-time monitoring video. The digital signal is easier to process and manage, for example, the video signal can be compressed, encrypted, etc., which improves the security and flexibility of the system; the switching instruction sent by the control button is transmitted through the radio frequency module, ensuring the real-time and reliability of the instruction transmission, and the user can switch the video source instantly, ensuring the continuity and timeliness of monitoring.

[0031] Working principle: the video host 4 processes the input signal of the camera and outputs an AHD analog video signal; the AHD analog video signal output by the video host 4 is connected to the receiver mainboard 2, digitally encoded, and then sent to the image transmission RF receiving module 52 through the image transmission RF transmitting module 51; the image transmission RF receiving module 52 receives the video digital signal and decodes it into an AHD analog video signal and then outputs it to the display screen for image display. When switching videos, the transmitter mainboard 1 sends the control button video switching command to the digital transmission RF receiving module 62 through the digital transmission RF transmitting module 61. After receiving the command, the digital transmission RF receiving module 62 is processed by the receiver mainboard 2 and sent to the video host 4 through the CANBUS link for video switching control, thereby realizing the operation of remotely switching the video screen.
