BTF2322-35 module-100 km Transmission+32-node networking, full coverage of tunnel and communication along the line. Yanuoxun has been deeply involved in wireless image transmission for more than ten years, and is well aware of the strict requirements of railway operation and maintenance for "long distance+anti-interference"—the BTF2322-35 module, a member of the BTF Series Wireless Video Transmission Modules, was born for this. Based on SDR architecture and COFDM modulation technology, it can realize 25-100 km stable transmission in complex terrain along the railway. The transmission power of 35dBm keeps the signal clear when it penetrates tunnels and mountains. As a "communication weapon" for railway operation and maintenance, its 4-hop 32-node self-organizing capability can cover long-distance railway lines: from interval inspection to monitoring along the line, multiple devices can seamlessly relay transmission, ensuring that the real-time picture of each line can be transmitted back to the operation and maintenance center. The one-way 47Mbps code rate meets the requirements of high-definition image recognition for micro-damage of rails. In terms of hardware design, it continues the "lightweight and reliable" characteristics of Yanuoxun: the weight of 250g is matched with the size of 93×81×22mm, which can be easily installed on the track inspection vehicle or the tower along the line; Power consumption ≤18W adapts to the power supply standard of railway equipment, and the wide temperature design from -40℃ to +70℃ is stress-free for extreme weather. Based on SDR architecture, BTF series focuses on ultra-long-distance (up to 500 kilometers) transmission and multi-node networking, and adapts to long-distance scenes such as railway operation and maintenance and cross-regional monitoring. Based on LTE standard, BTD Series focuses on low power consumption and environmental adaptability, and adapts to fixed monitoring, maritime monitoring and other close-range scenes, which complement each other in terms of technical bottom layer and scene adaptability. As an excellent Graphics Data Transmission Module, it excels in data transmission. At present, the module has been applied in several railway trunk lines, and it has shown outstanding performance in scenes such as signal enhancement in tunnels and bridge inspection. Its low delay of less than 10ms and AES256 encryption not only ensure the immediate transmission of fault warning, but also prevent data leakage, and truly become a "communication barrier" for the safe operation of railways. This Image Data Transmitter also meets the high standards of railway communication in practical use. Whether it is the transmission of on-site images or the sending of operation and maintenance data, it can complete the task efficiently and stably. FAQ： 1.Will the transmission of Modules in railway tunnels be affected? 35dBm transmission power with COFDM technology can penetrate the tunnel shielding, and -95dBm high sensitivity can capture weak signals to ensure stable communication between the inside and outside of the tunnel. 2.How long can a 4-hop 32-node network cover? Each hop can transmit 25-100 kilometers, and the maximum coverage of 4 hops is about 400 kilometers, which is suitable for sectional monitoring of inter-provincial railway trunk lines, and each node automatically relays transmission. 3.On which railway equipment is the weight of 250g suitable for installation? It can be easily mounted on railway inspection unmanned aerial vehicles and track inspection vehicles, and can also be fixed on towers along the line, with light weight and convenient installation, without affecting the normal operation of equipment. 4.Power consumption ≤18W, can it adapt to the power supply system of railway equipment? Fully adapted, the railway patrol car and emergency power supply along the line can supply power stably, without additional high-power power supply, and it is suitable for long-term outdoor operation.
