The invention discloses a data link system based on an IMA architecture. The system includes: a display for providing a man-machine interface for a data link application; an IMA chassis in which a data link application and an air-to-ground communication protocol stack reside; and a remote data interface The unit is used to communicate between the IMA chassis and the radio station to realize the mutual conversion between AFDX data and ARINC429 data; the radio station is used to receive control commands from data link applications and perform corresponding operations; it is used to receive data from The downlink message of the chain protocol stack is sent to the ground; it is used to receive the uplink message sent by the ground and send it to the data link protocol stack; among them, the data link application software runs in the partition operating system of the IMA chassis, and the data link applications communicate with each other It forms the isolation of operating space and time, and realizes the technical effect of reasonable design of the measurement system and accurate measurement results of geometric parameter detection.
Description
technical field [0001] The invention relates to the field of avionics systems, in particular to a data link system based on an IMA architecture. Background technique [0002] The civil aircraft avionics system has now entered the era of integrated modular avionics IMA architecture. The IMA avionics system is composed of the IMA platform and related resident applications, which can share a set of changeable, reusable and interoperable hardware and software resources. Under this architecture, multiple field-replaceable high-performance units of different types can be accommodated in the same physical rack or chassis, and shared by partitions, thereby significantly reducing product volume and weight, and improving system integration and reliability. sex. [0003] In contrast to IMA, communication management units based on the federal avionics system architecture, such as Honeywell's CMU MK2 equipment and Collins' CMU900 equipment, do not include all current application, and ...
