Abstract

The invention provides a data communication method among all independent subsystems in an integrated airborne collision avoidance system. The method comprises the steps that an RAM area for data communication is formed in an FPGA (Field Programmable Gate Array) chip of a signal processing module; if the subsystem A needs to perform data communication with other N subsystems, N data areas in one to one correspondence and N control areas in one to one correspondence for the subsystem A to face the other N subsystems are arranged in the RAM area, otherwise, if the other N subsystems need to perform data communication with the subsystem A, a respective data area and a corresponding control area for each of the other N subsystems to face the subsystem A are arranged in the RAM area; by the designed communication structure and communication protocol, effectiveness and safety of effective data communication among all the independent subsystems are improved.

Description

technical field

[0001] The invention relates to a data communication method between independent subsystems in an integrated airborne collision avoidance system, in particular to a method applicable to the field of air traffic control 3 A data communication method between independent subsystems in the CAS integrated airborne collision avoidance system. Background technique

[0002] T 3 CAS Airborne Collision Avoidance System is a comprehensive airborne collision avoidance system, which is mainly used to provide air safety separation guarantee for aircraft to achieve the purpose of anti-collision. T 3 The CAS airborne collision avoidance system has high real-time and high-speed data processing. T 3 The CAS airborne collision avoidance system itself has many functions, and the data processing is extremely complicated. In the prior art, in order to ensure the high speed of data processing, the T 3 The CAS airborne collision avoidance system is divided into several independe...
