南宁机场二跑道自动气象观测系统信号传输方案
Signal Transmission Scheme for the Automatic Weather Observing System at Nanning Airport’s Second Runway

南宁机场第二跑道建设是区域航空枢纽升级的关键工程，其自动气象观测系统(Automated Weather Observing System, AWOS)的信号传输可靠性直接关系到航班运行的安全与效率。鉴于传统信号传输存在单点故障风险高、冗余设计不完善等问题，文章提出一种三级容错架构方案，通过主/备用设备分离、双链路并行传输及独立供电设计，系统性降低了故障概率，提升了信号传输的稳定性与可靠性，为南宁机场二跑道的安全运行筑牢气象数据传输保障。
The construction of the second runway at Nanning Airport is a critical project for the upgrade of the regional aviation hub. The reliability of the signal transmission of the Automated Weather Observing System (AWOS) directly impacts flight safety and efficiency. Given the high risk of single-point failures and inadequate redundancy design in traditional signal transmission systems, this paper proposes a three-level fault-tolerant architecture. This scheme systematically reduces the probability of failures and enhances the stability and reliability of signal transmission by separating primary and backup equipment, implementing dual-link parallel transmission, and designing independent power supply systems. This approach ensures robust meteorological data transmission, thereby safeguarding the safe operation of the second runway at Nanning Airport.
