The system has the advantages that the system uses an industrial personal computer as the comprehensive information processing platform to integrate the operation and control information and execution state information of various photoelectric detectors, and the system adopts a cabinet layout and comprises a comprehensive display unit, a task machine simulation unit and a helmet simulation unit; the system uses the AFDX bus as the external communication interface bus of the control system, communication speed and reliability are increased, and equipment interconnection complexity is lowered; a graphic and modularized man-machine interaction control interface is provided, and the functions and various performance of the various photoelectric detectors can be detected; meanwhile, a curve drawing method based on a double-buffer mechanism is adopted, and follow-up angles and feedback angles can be visually reflected.

Description

technical field [0001] The invention relates to the technical field of airborne photoelectric control, in particular to an AFDX bus-based helicopter photoelectric analog control system and method. Background technique [0002] The photoelectric stabilizing pod is an important part of the helicopter platform, which has comprehensive display functions such as day and night observation, search and target indication. During the research and development and production process of the photoelectric stabilization pod, its various performance indicators and the functions of photoelectric detectors need to be tested. The above functions and performance tests need to be realized through the AFDX bus control simulation helicopter control system, so the simulation of helicopter AFDX bus avionics control has become an inevitable trend, and it is very important to design an AFDX bus based avionics control simulation system. [0003] At present, the AFDX bus avionics control device suitabl...
