目前,我国导航台站使用的全向信标大多数为澳大利亚AWA公司生产的,以VRB-51D型多普勒全向信标为主,使用十几年以上。各个导航台都出现过不同的故障,在使用维护过程中积累了一定的经验,现结合故障现象谈谈对AWA全向信标的维护检修。假如把设备比作病人,医生通过“望、闻、切、问”给病人义诊,对症下药,使病人早日得到康复,这与我们维修设备过程非常相似。“望”和“闻”是第一步观察设备故障现象阶段;“切”和“问”是第二步故障检测 At present, most of the omni-directional beacons used by navigation stations in China are produced by AWA Company in Australia and are mainly used in the multi-directional omni-directional VRB-51D Doppler and more than ten years. Various navigation stations have appeared in different faults, the use of the maintenance process has accumulated some experience, are combined with the phenomenon of failure to talk about the AWA omni-directional beacon maintenance and repair. If the device is likened to a patient, the doctor can give the patient a free hand by “looking, smelling, cutting, asking” to remedy the problem and recover the patient as soon as possible, which is very similar to the process of repairing the equipment. “Look ” and “smell ” is the first step to observe the phenomenon of equipment failure phenomenon; “cut ” and “ask ” is the second step fault detection
