Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to wireless video transmission devices using various methods. Background Technology

[0002] Wireless video backhaul devices are equipment that can wirelessly transmit video signals back to the receiving end. They are widely used in news gathering, surveillance, film and television production, drones, and other fields. Their main function is to achieve remote video transmission, avoiding the limitations of traditional wired transmission and improving flexibility and real-time performance. Through various transmission methods (such as Wi-Fi, 4G / 5G, satellite, etc.), wireless video backhaul devices can optimize transmission performance in different environments, enhance signal stability and coverage, improve data transmission rates, and ensure video quality. This better meets the needs of different application scenarios, especially in complex or mobile environments, providing stronger adaptability and reliability.

[0003] With the development of wireless video backhaul technology, existing traditional wireless video backhaul devices mainly rely on a single propagation method for data transmission, such as Wi-Fi or 4G / 5G networks. While these devices can meet video transmission requirements to a certain extent, they often face limitations in propagation methods in practical applications. For example, in some remote areas or environments with unstable signals, traditional Wi-Fi or 4G / 5G networks may not provide stable transmission rates, resulting in poor video backhaul performance or even interruptions. Furthermore, most existing devices are designed for a single propagation method and cannot flexibly switch between multiple transmission methods to supplement or replace them. This imposes significant limitations on usage in scenarios requiring high-quality, stable transmission. Therefore, this paper proposes several wireless video backhaul devices to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a variety of wireless video backhaul devices, aiming to improve the problem that traditional wireless video backhaul devices in the prior art have a relatively single transmission method when transmitting data, and require the replacement of equipment according to different environments, resulting in unnecessary consumption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-mode wireless video backhaul device, including a housing, a transmission component for backhauling video data fixedly connected to the outside of the housing, four connecting shafts detachably connected to the bottom of the housing, a rotating ball rotatably connected to the bottom of the four connecting shafts, a support shaft fixedly connected to the bottom of the rotating ball, multiple sliding shafts slidably connected to the outside of the support shaft, the rotating ball fixedly connected to the bottom of the support shaft, a fixed seat rotatably connected to the bottom of the rotating ball, and a fixing screw detachably connected to the inside of the connecting shaft;

[0006] As a further description of the above technical solution: the transmission component includes a telescopic rod, the telescopic rod is fixedly connected to the outside of the housing, a transmission antenna is fixedly connected to the top of the telescopic rod, there are two telescopic rods, the two telescopic rods are fixedly connected to both sides of the housing, and a satellite antenna is fixedly connected to the outside of the housing;

[0007] As a further description of the above technical solution: a storage battery is fixedly connected inside the housing, a power cord is fixedly connected outside the storage battery, and a motherboard is fixedly connected to the top of the power cord;

[0008] As a further description of the above technical solution: three fixing blocks are fixedly connected to the top of the inner side of the housing. A Wi-Fi video encoder is fixedly connected to the top of the upper left fixing block, a 4G / 5G video encoder is fixedly connected to the top of the upper right fixing block, and a high-speed video encoder is fixedly connected to the top of the lower right fixing block. The Wi-Fi video encoder, the 4G / 5G video encoder, and the high-speed video encoder are provided with a video data interface, a video encoding data interface, and a power interface on their exteriors.

[0009] As a further description of the above technical solution: The motherboard has a video data interface and a power interface on its top four sides. A video data transmission line is fixedly connected inside the video data interface, and a power line is fixedly connected inside the power interface. The other end of the video data transmission line is fixedly connected to the video interface on the outside of the Wi-Fi video encoder, and the other end of the power line is fixedly connected to the power interface on the outside of the Wi-Fi video encoder.

[0010] As a further description of the above technical solution: the video encoding data interface opened on the outside of the Wi-Fi video encoder is internally fixedly connected to an encoding data transmission line; the video data interface opened on the outside of the 4G / 5G video encoder is internally fixedly connected to an encoding data transmission line; and the video encoding data interface opened on the outside of the high-speed video encoder is internally fixedly connected to an encoding data transmission line.

[0012] As a further description of the above technical solution: a charging port is fixedly connected to the outside of the housing.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the fixed environment of the device vibrates, the fixed seat remains fixed in the environment and moves with the environment. The presence of the rotating ball allows the rotating ball and the support shaft connected to the rotating ball to rotate adaptively when the fixed seat moves. Multiple sliding shafts ensure that the device will not tilt after the support shaft rotates, thereby achieving the vibration isolation effect.

[0015] 2. In this utility model, the video data captured by the camera is transmitted to the motherboard via a video data transmission line. Depending on the compatibility of the model with the environment, the motherboard transmits the video data to a Wi-Fi video encoder, a 4G / 5G video encoder, and a high-speed video encoder via the video data transmission line for encoding. The Wi-Fi video encoder transmits via Wi-Fi, the 4G / 5G video encoder transmits via 4G / 5G, and the high-speed video encoder transmits via satellite. The encoded video data is then transmitted to the transmission antenna or satellite antenna via the encoding data transmission line. The multiple transmission methods expand the practicality and adaptability of the device and reduce the consumption of video transmission. Attached Figure Description

A motherboard 6 is fixedly connected to the top of the power cord 11. The motherboard 6 is the control core of the entire device, responsible for managing the transmission, encoding, and processing of video data. The motherboard 6 communicates with components such as the video encoder, power supply, and antenna through multiple interfaces and coordinates the operation of each component. Three fixing blocks 15 are fixedly connected to the top of the interior of the housing 1, providing installation positions for the video encoder and providing stable support.

It connects to the motherboard 6 via a video data interface and a power interface. A 4G / 5G video encoder 8 is fixedly connected to the top of the upper right fixed block 15. The 4G / 5G video encoder 8 supports video data transmission via 4G or 5G networks. 4G / 5G encoders typically have lower latency and higher bandwidth, enabling stable transmission of high-definition video in a wide range of wireless network environments. A high-speed video encoder 14 is fixedly connected to the top of the lower right fixed block 15, providing high-speed encoding of video data, thereby reducing bandwidth pressure during satellite transmission. The Wi-Fi video encoder 7, 4G / 5G video encoder 8, and high-speed video encoder 14 are externally equipped with video data interfaces, video encoding data interfaces, and power interfaces. The motherboard 6 has video data interfaces and power interfaces around its top.

An encoding data transmission cable 9 is fixedly connected inside the external video encoding data interface of the high-speed video encoder 14. A camera 12 is fixedly connected to the outside of the housing 1. The camera 12 is the video acquisition part of the entire system, responsible for capturing video images in real time. A video data transmission cable 10 is fixedly connected to the bottom of the camera 12. A charging port 21 is fixedly connected to the outside of the housing 1. The charging port 21 is used for charging the device's battery and supports external power input to ensure power supply during long-term operation.

[0025] Working principle: The device's operation begins with camera 12, which is responsible for acquiring video data in real time and transmitting the acquired video signals to each video encoder via video data transmission line 10. Specifically, camera 12 is fixedly connected to the exterior of the housing to ensure stable video signal transmission.

[0026] The video data acquired by camera 12 is transmitted to motherboard 6 via video data transmission line 10. Motherboard 6 is responsible for coordinating the operation of the entire device, including video data processing and encoding. Motherboard 6 transmits the data to different video encoders (such as Wi-Fi video encoder 7, 4G / 5G video encoder 8, and high-speed video encoder 14) as needed. These encoders process video data under different networks using their encoding capabilities: Wi-Fi video encoder 7 compresses the video signal into a format suitable for Wi-Fi network transmission; 4G / 5G video encoder 8 processes video data suitable for 4G or 5G network backhaul, ensuring low latency and high bandwidth transmission; high-speed video encoder 14 performs high-speed encoding of the video signal, reducing the bandwidth pressure on satellite transmission. These video encoders transmit the encoded data to transmission antenna 4 via encoding data transmission line 9 for wireless signal backhaul. Transmission antenna 4 provides adjustable height and angle via telescopic rod 3, ensuring signal stability and coverage in different environments. Multiple transmission antennas 4 and telescopic rod 3 work together to support signal backhaul across multiple frequency bands such as Wi-Fi and 4G / 5G, ensuring stable operation of the device over long distances.

[0027] The device is also equipped with a satellite antenna 2 for satellite communication, ensuring data transmission even in areas without other network coverage. For power, a battery 5 provides power to the device and distributes power to various electrical components via a power cord 11, ensuring the normal operation of all parts of the device.

[0028] When the equipment vibrates, the connecting shaft 20 and the rotating ball 16 help adjust the equipment angle and maintain its stability. The support shaft 18 and sliding shaft 17 connected to the rotating ball 16 further ensure that the equipment will not collapse under vibration, thus guaranteeing the smooth operation of the equipment.

[0029] In addition, the device supports charging port 21 to provide external power input to battery 5, ensuring the power required for long-term operation. The device's control core motherboard 6, through communication and cooperation with various components, ensures that the device is always in optimal working condition and can adjust the video transmission mode according to different environments.
