BTF2322-35 module-Anti-interference+low delay, dual adaptation of rail detection and emergency command For railway operation and maintenance, "communication without dead ends" is the premise to ensure safety. The BTF2322-35 module, a member of the BTF Series Wireless Video Transmission Modules, built by Yanuoxun with more than ten years of technology accumulation, fills the pain point of long-distance railway communication with 100 km Transmission distance and strong anti-interference ability. The core competitiveness of this module lies in "long-distance stability": COFDM modulation technology can still resist multipath interference when the signal is moving at high speed (such as when the inspection vehicle is driving), and the sensitivity of -95dBm ensures no packet loss in weak signal areas such as mountains and tunnels. A 4-hop 32-node ad hoc network is like "building a temporary communication chain", which allows devices along the line to form a linkage network. As an excellent Graphics Data Transmission Module, it performs well in data transmission. Practically, it fully considers the requirements of railway scenes: 250g weight is convenient to install on towers or detection equipment, and power consumption ≤18W is suitable for vehicle-mounted power supply; 2 network port+3 serial port can be directly connected with infrared detector and other equipment to realize synchronous transmission of data and pictures. AES256 encryption is more in line with the railway data security specification. 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. This Image Data Transmitter also shows great capability in practical application. From the actual operation and maintenance point of view, whether it is the real-time monitoring along the high-speed rail or the hidden trouble investigation of the old railway, the module can play stably: the rail images taken by the inspection vehicle can be transmitted back in real time, and the operation and maintenance personnel can judge the damage remotely in the center; In case of sudden weather, it can also ensure that the state data of equipment along the line is not interrupted, thus escorting the railway safety. FAQ： 1.Will the strong electromagnetic environment along the railway affect the module signal? The module adopts SDR architecture and anti-interference design, which can resist electromagnetic interference generated by transmission lines and train operation and ensure stable signal transmission. 2.What is the significance of < 10ms delay to railway emergency command? It can realize the immediate response of "scene picture feedback-instruction issuing". For example, in case of sudden failure, the command center can quickly issue disposal instructions to inspection personnel to reduce the delay. 3.Can rail inspection data and video images be transmitted at the same time? Yes, the bit rate of 47Mbps supports the synchronous transmission of video images and detection data (such as rail wear parameters), which meets the requirements of "visualization+digitization" for railway inspection. 4.What is the signal stability in remote areas such as mountain railways? After multi-scene verification, in remote areas such as mountains and bridges, the module can still maintain 25-100 km transmission, and 32-node networking can cover remote road sections and avoid signal blind spots.
