摘　　要：飞机通信寻址和报告系统(aircraft communication addressing and reporting system,ACARS)是一种航空器和地面站之间通过无线电或卫星传输短消息的数字数据链系统。在"基于状态的维修"(condition based maintenance,CBM)的思想上,提出一种基于ACARS的机载气象雷达实时故障监控方法。该方法从真实的机载数据出发,在设备失效测试的基础上分析机载气象雷达故障字,从而设计用于实时故障监控的机载ACARS报文,并通过空地协同工作的方式,利用机载设备、地空数据链和地面维护系统等实现空地一体化的故障监控。实际装机测试表明,该方法可有效地识别机载气象雷达系统故障,减少故障误判,缩短排故时间,降低航空运营成本。Aircraft communication addressing and reporting system（ACARS） is a data link system of short message transmission between aircraft and ground stations via radio or satellite. According to condition based maintenance, a real-time fault monitoring method for airborne weather radar based on ACARS is proposed. Starting with the real airborne data, the fault words of airborne weather radar are analyzed based on the equipment failure test;meanwhile, ACARS report which is used for real-time fault monitoring is designed. With the air and ground cooperation, real-time fault monitoring of airborne weather radar is realized by using airborne equipment, air-ground data link and ground maintenance system. Actual tests show that this method can identify the fault of airborne weather radar system effectively, and reduce fault misjudgment, troubleshooting time and air operation costs.
