浅谈新一代天气雷达的日常维护与故障分析及排除

吴宏伟

【摘  要】要想充分发挥新一代天气雷达在气象决策与服务、天气预报、人工影响天气等业务中的优势和作用，就要重视新一代天气雷达的日常维护以及故障排除的研究分析，并借助继电器开关来对伺服控制单元、发射机主控板以及数据采集控制单元等设备设施电源进行有效控制，还要重视以信号波形实施监控，以便实施快速在线诊断。论文根据相关从业经验并结合广泛的社会实践调查研究，就新一代天气雷达的日常维护与故障分析及排除展开了相关的探讨，望能提供借鉴。

【Abstract】If we want to give full play to the advantages and roles of the new generation weather radar in meteorological decision-making and services， weather forecasting， weather modification and other operations， we must pay attention to the research and analysis of daily maintenance and fault elimination of the new generation weather radar. With the help of relay switch， the power supply of servo control unit， transmitter main control board， data acquisition control unit and other equipment and facilities can be effectively controlled. Moreover， attention should be paid to monitoring with signal waveform to implement rapid online diagnosis. Based on relevant working experience and extensive social practice investigation and research， this paper discusses the daily maintenance and fault analysis and elimination of the new generation weather radar， hoping to provide reference.

1 引言

随着社会经济的不断发展，科学技术水平的不断提升，我国新一代天气雷达网建成，而新一代天气雷达网探测资料的开发及广泛应用，给我国国内气象管理、天气预报业务开展以及气象建设等带来了新的机遇及挑战，要准确监测、预报气象，充分发挥新一代天气雷达的作用，但由于新一代天气雷达起步比较晚，且发展十分迅速，缺乏一定的技术支持及经验，而且新一代天气雷达绝大多数都布置在偏远地区或环境比较恶劣的高山上，所以在新一代天气雷达出现故障时，不能及时、准确地找到雷达故障点，导致天气雷达维修及故障分析存在问题，所以要重视新一代雷达的日常维护与故障分析及排除，提高新一代雷达的日常维护及故障排除效益，进而有效保障新一代天气雷达业务的可用性。……
