本实用新型属于航空电子技术领域，具体涉及一种免维护航空防护记录器。The utility model belongs to the technical field of avionics, in particular to a maintenance-free aviation protection recorder.
背景技术Background technique
航空记录器是飞行参数系统的重要组件，主要记录航空器的飞行数据，用于支持飞行事故调查。通常航空记录器具有抗强冲击、耐高温火烧等特性，能确保飞行事故发生后记录的飞行数据能被可靠读取；其中内部记录飞行数据的芯片因被特殊结构件包裹，无法实现快速读取数据。因此日常对航空记录器的维护过程中，需要专业人员使用地面专用飞参数据下载设备对数据进行下载，以判断航空记录器的运行状态。目前这种典型的航空记录器飞行数据下载维护方式需要在地面配备专门的设备和人员，并且需要占用一定的数据下载时间。The aviation recorder is an important component of the flight parameter system, which mainly records the flight data of the aircraft and is used to support the investigation of flight accidents. Generally, aviation recorders have the characteristics of strong impact resistance, high temperature resistance and fire resistance, which can ensure that the recorded flight data after the flight accident can be read reliably; the internal recording flight data chip cannot be quickly read because it is wrapped by special structural parts data. Therefore, during the daily maintenance of the aviation recorder, professionals are required to download the data using a ground-specific flight parameter data download device to judge the operating status of the aviation recorder. At present, this typical way of downloading and maintaining flight data of aviation recorders requires special equipment and personnel on the ground, and takes a certain amount of time for data downloading.
为了尽量减少航空器地面维护时间，目前通常在飞行参数系统上，增加快取记录器。快取记录器与航空记录器分别同时接收飞参采集器的数据，飞行结束后，通过拔取快取记录器中的快取卡直接获取飞行数据(航空记录器机上交联示意图见图2)，从而实现飞行数据的快速读取，避免再去下载航空记录器中飞行参数。但是，当快取记录器正常记录飞行数据时，航空记录器可能出现已损坏无法记录飞行数据并未报出故障(任何设备都无法100％检测故障)的现象；如果航空器在这种情况下再出现严重飞行事故时，航空记录器因损坏无法记录飞行数据，快取记录器因无防护措施无法保护飞行数据；最后航空器极有可能因无飞行数据无法支持事故调查导致事故调查失败，带来不可估量的后果。因此，需要一种能实现免维护又能可靠记录飞行数据的航空记录器。In order to minimize the maintenance time of the aircraft on the ground, a cache recorder is usually added to the flight parameter system. The cache recorder and the aviation recorder respectively receive the data of the flight reference collector at the same time. After the flight is over, the flight data can be obtained directly by pulling out the cache card in the cache recorder (see Figure 2 for the on-board cross-linking diagram of the aviation recorder). In this way, the rapid reading of flight data can be realized, and the flight parameters in the aviation recorder can be avoided to be downloaded again. However, when the cache recorder normally records the flight data, the aviation recorder may be damaged and unable to record the flight data and report a failure (no equipment can detect the failure 100%); When a serious flight accident occurs, the aviation recorder cannot record the flight data due to damage, and the cache recorder cannot protect the flight data due to lack of protective measures; in the end, the aircraft is very likely to fail the accident investigation due to lack of flight data and cannot support the accident investigation, which will bring disastrous results. estimated consequences. Therefore, there is a need for an aviation recorder that can realize maintenance-free and reliably record flight data.
