The communication part of the military field comprehensive communication vehicle mainly includes three parts, namely wireless communication equipment, wired communication equipment, and power supply equipment. Communication vehicles must have good lightning protection design. During outdoor operation, due to the influence of antennas, signal transmission, etc., they are easily affected by lightning strikes in severe weather, which not only poses a great threat to the safety of equipment and personnel, but also affects the quality of communication signals. At present, military communication vehicles must support various functional features such as wireless communication, wired communication, high-speed bandwidth, high-definition video, voice, encryption, and anti-interference for field communication.
The communication vehicle of a certain branch of the army adopts the X4F04 and X4S04 communication modules from Xiayu as the core components to form a programmable magnetic telephone exchange system, which realizes functions such as feeding, overvoltage protection, ringing, monitoring, encoding and decoding, mixing, polarity detection, 24 line conversion, loop control, on hook transmission, and incoming call display. It has strong confidentiality, low heat generation, wide temperature operation, stable functions, and maintains high fidelity of voice call quality.
