You should understand this knowledge about drone image transmission equipment.

The UAV image transmission equipment is mainly used for the transmission of UAV video signals. It is the core equipment of the UAV system. It adopts appropriate video compression technology, signal processing technology, channel coding technology and modulation and demodulation technology to bring the scene. The video captured by the camera of the drone is transmitted wirelessly in real time to a wireless electronic transmission device at a long distance. Therefore, the drone image transmission device is also called the "eye" of the drone.

According to the quality of UAV's picture transmission equipment, it can be divided into consumer drones and industrial drones. With the booming development of the drone industry, drone image transmission equipment has become indispensable for industry drones. important role. Unlike consumer-grade drones, industrial-grade drones undertake industry-specific tasks, but the common feature of both is that they can observe or acquire live images and videos in real time and reliably in the vast majority of situations that need to be away from the field. .
Generally, according to the type of drone image transmission equipment, it can be divided into analog image transmission and digital image transmission. Since the quality and stability of video transmitted by digital image transmission are much better than analog image transmission system, it is industrial grade. Digital image transmission is usually used in applications. The digital image transmission can be subdivided into D1 (720*576), HD 720i/p (1280*720) and Full HD 1080 i/p (1920*1080) according to the pixel resolution of each frame of the transmitted video. .
At present, the standard and resolution of full HD pictures on the market are mainly 1080i and 1080p. The common frame rate can be divided into four types: 25fps, 30fps, 50fps and 60fps. The bandwidth is also divided into 4MHz, 6MHz and 8MHz. The actual code stream speed ranges from 2Mbps to 12Mbps, and the end-to-end transmission delay is basically between 400ms and 1200ms. The effective transmission distance of 1W transmit power ranges from several hundred meters to about 20km.
But even the full HD level of image transmission, there are great differences in terms of transmission format, bandwidth, frame rate actual code stream speed, transmission delay, and effective transmission distance.
It should be noted that the i/p system (interlace/progressive), frame rate, actual code stream speed, image transmission delay and effective transmission distance are different. When viewing the video or actual application, the image is displayed. The difference in user experience in terms of detail, image fluency, image dynamic scene changes, image color transition softness, and environmental adaptability is very large.
At present, Tengzhi Zhituo's UAV image transmission equipment is at the high-end level in the industry. Under the same transmission power conditions, Tengyuan Zhituo UAV image transmission equipment has effective transmission distance, transmission delay and image quality. The indicators such as video fluency or image dynamic scene changes have reached the current high-end level in the industry. The ST1410KP UAV image transmission device launched by Tengyuan Zhituo is a wireless transmission product designed by Tengyuan Zhituo based on the self-developed OFDM baseband algorithm. It has large bandwidth, long distance, strong anti-interference ability and strong diffraction performance. . Transmission distance can reach 50KM.

The main differences between the consumer-grade UAV map transmission system and the industrial-grade UAV map transmission system are: the effective transmission distance of the system, the stability of the system, the reliability of the system, and the environmental adaptability of the system. The industrial-level image transmission system has far higher indicators in these aspects than the consumer-grade image transmission products. Therefore, the design ideas, manufacturing processes and test conditions of industrial-grade image transmission products are completely different.
High resolution, high frame rate and long-distance transmission are the inevitable trends in the development of wireless transmission equipment. The immature technology of UAV transmission equipment has always been an important part of limiting the development of the UAV industry. Looking at the entire market, there are only a handful of manufacturers that can provide high-quality image transmission equipment, and Tengyuan Zhituo, which has 12 years of experience in R&D of wireless transmission equipment, is one of the manufacturers who have mastered the core technology of UAV image transmission equipment.
