Abstract

The invention discloses a multi-bus interface system of an airborne transponder. The multi-bus interface system includes a multi-bus input module, a Logic control module, a data processing module andan output module, wherein the logic control module comprises a protocol analysis module and a parallel bus logic control module; the multi-bus input module is correspondingly connected with the parallel bus logic control module through the protocol analysis module or directly, and the parallel bus logic control module is correspondingly connected with the output module through the data processingmodule. The multi-bus interface system is compatible with four airborne buses, namely an ARINC429 bus. 1553B bus, an RS422 bus and a CAN bus. When the airborne transponder provided with the system isused for replacing an aircraft platform, replacement of the aircraft platform can be realized only by changing a software configuration file, the hardware and the embedded software of the airborne transponder can be kept unchanged, and the change of the airborne transponder caused by the change of an airborne bus is reduced to the minimum.

Description

technical field [0001] The invention relates to surveillance radar equipment, in particular to an airborne transponder multi-bus interface system. Background technique [0002] The airborne transponder belongs to the secondary surveillance radar equipment that the aircraft must equip. It receives the secondary surveillance radar interrogation signal from space through the antenna, and transmits the aircraft's flight altitude, flight number or mission information and other signals back through the antenna, so as to realize Ground-to-aircraft surveillance and flight management. The airborne transponder consists of at least the answering host and the answering antenna, and its control methods are divided into two types: 1) use the control box matched with the answering host, and implement control by operating the panel switch of the control box; 2) use the onboard bus communication technology, through The on-board bus sends commands to implement control. At present, the airbo...
