Abstract

The invention discloses an aircraft hardware-in-the-loop access test measurement and control system. An object-oriented design idea is adopted, a real-time clock serves as a unified clock of the whole system, an optical fiber reflective memory serves as a communication network, and the real time performance of the whole system is improved. The aircraft hardware-in-the-loop access test measurement and control system can be applied to aircraft hardware-in-the-loop simulation. The aircraft hardware-in-the-loop access test measurement and control system achieves microsecond-level real-time scheduling and communication of a plurality of distributed nodes, has an RS422, 1553B and optical fiber reflective memory network common interface, can be used for having access to devices for detection, guidance, control and the like of aircrafts, and achieves mutual operation of devices and models of different step lengths and time constraints.

Description

Technical field [0001] The invention relates to an aircraft semi-physical connection test measurement and control system, which belongs to the technical field of spacecraft test measurement and control. Background technique [0002] The complexity and modernization of aerospace systems continue to increase, making their design, development and maintenance increasingly dependent on advanced testing, testing and testing methods. At present, many large-scale and complex aerospace test and test systems have integrated several subsystems, components or equipment, and their composition is also developing in the direction of distributed, networked and general-purpose computer-based composition. Therefore, in order to construct a test and test system with excellent performance, advanced system integration technology must be applied. [0003] The invention is suitable for communication management and control of semi-physical simulation of offensive and defensive confrontation between diffe...
