A unified system for transfer of mission critical data to line replaceable units over a digital avionics bus

摘要

Refer Figure 1 Figure 1 This invention presents a system that provides the facility to upload and download data for different Line Replaceable Units (LRU) (105, 106, 107. etc.) in an aircraft in a unified package. The traditional method has been to use dedicated ground servicing equipment for different LRUs for data transfer. Here, these functionalities have been centralized by using a single sub-system, the Data Loader Unit (101) as the source of data. It is provided with a Removable Storage Medium (102) for storing data related to various LRUs. The Data Transfer Controller (103) controls the entire process. It receives the stored data from the Data Loader Unit (101), processes it to check for errors, encodes the data for the respective LRU and transfers it over an avionics bus. It also retrieves data from the LRUs and transmits it to the Data Loader Unit (101) for storage and post-flight analysis.
