Abstract

The invention belongs to the technical field of flight control systems, and relates to a method for sending and reproducing data of a helicopter flight control system. A configuration table is added to the memory of a flight control computer, and the data is configured before the data is sent. The configuration information is read and displayed during initialization. Carry out data processing and sending according to configuration information; The described reappearance method sets the data update flag word in the data reappearance software, and the lost data is supplemented; The configuration eliminates the work of changing and verifying the software of the flight control system, and uses the data update flag to automatically fill in the lost data, eliminating the distortion when the data is reproduced.

Description

Technical field [0001] The present invention belongs to the technical field of flight control systems, to a helicopter flight control system and a reproduction method for data transmission. Background technique [0002] Flight Recorder is one of the modern aircraft equipment must be installed, initially, it is only as a means of investigation to help investigators in a major accident. Now, with the development of bus technology, data storage technology, flight control system dedicated data logger has become an important means for the designer to optimize the design of the flight control system. [0003] Appeared in the form of a bus using RS422 / 232, ARINC429 other data logger in a helicopter, they can be used for flight control system stores data in real time, and by other means to store data reproduction. [0004] Storage and reproduction Flight Control data is divided into three parts: [0005] Data transmission: refers to a flight control data in the flight control computer ...
