中国民用航空领域中传统陆基导航设备依旧占据着重要作用。作为航路导航和部分终端导航的主要陆基导航设备,全向信标DVOR和测距仪DME肩负着近乎所有中国民用航空器的航路导航任务。航路导航的主要部分是通过DVOR提供的方位信息以及DME提供的距离信息构成的,迄今国内的DVOR全向信标设备主要包括thales4000型和thales432型,其中又以4000型为主。本文希望通过该则DVOR4000型设备的放大器板件的故障案例,对通过故障现象的判定和信号流程的分析来确定故障位置的方法进行学习,从而提升设备故障板件的自主维修能力。
The traditional land-based navigation equipment in the field of civil aviation in China still plays an important role. As the main land-based navigation device for en route navigation and partial terminal navigation, the omnidirectional beacon DVOR and the DME rangefinder have navigation missions to nearly all Chinese civil aircraft. The main part of navigation route is formed by the location information provided by DVOR and the distance information provided by DME. Up till now, the DVOR omnidirectional beacon equipment mainly includes thales4000 type and thales432 type, of which 4000 type is the main type. In this paper, we hope that through the DVOR4000 equipment amplifier board pieces of the case of failure, through the determination of the phenomenon of failure and signal flow analysis to determine the location of the fault method to learn, thereby enhancing the ability of autonomous equipment failure plate repair.
