specific Embodiment 1

[0052] Arinc429 communication system self-test system, including

[0053] The hardware detection module of the Arinc429 communication system detects the integrity and correctness of the data received and sent by the hardware of the Arinc429 communication system;

[0054] The start-up state judging module judges whether the Arinc429 communication system is currently in the start-up state;

[0055] The detection result reporting module reports the detection result to the transceiver host performance monitoring module.

[0056] The self-inspection method is: judge whether the Arinc429 communication system is currently in the startup state, if so, according to the designed test process, start the inner loopback test and the outer loopback test respectively, and complete the parameter configuration work of the Arinc429 communication system configuration area according to the test requirements, Create a test task, and complete the correctness detection of the Arinc429 communication...

specific Embodiment 2

[0057] On the basis of specific embodiment 1, described self-inspection system also comprises: the hardware configuration monitoring module of Arinc429 communication system, the hardware configuration area state of Arinc429 communication system is periodically detected;

[0058] The running status judging module judges whether the Arinc429 communication system is currently running.

[0059] Its self-inspection method is: judge whether the Arinc429 communication system is currently in the start-up state or the running state; if it is in the start-up state, after completing the hardware part detection of the Arinc429 communication system, periodically detect the state of the hardware configuration area of ​​the Arinc429 communication system; If it is in the running state, then periodically detect the state of the hardware configuration area of ​​the Arinc429 communication system.

specific Embodiment 3

[0060] On the basis of specific embodiment 2, the hardware configuration detection module of the Arinc429 communication system includes,

[0061] The hardware configuration area state has an error judging module to judge whether the hardware configuration area state has an error state;

[0062] Reconfigure the module to reconfigure the hardware configuration area of ​​the Arinc429 communication system.

[0063] The specific method for periodically detecting the state of the hardware configuration area of ​​the Arinc429 communication system is: detect the state of the hardware configuration area of ​​the Arinc429 communication system, and judge whether there is an error in the state of the hardware configuration area parameters in the startup state or running state; if it is , the configuration area is restored to the normal configuration, and an error record is generated; the normal configuration refers to the configuration parameters of the hardware configuration area adopted...

Abstract

The invention provides a self-checking system and method for an Arinc 429 communication system. The method comprises detecting the hardware part of the Arinc 429 communication system, monitoring the hardware configuration of the Arinc 429 communication system, and monitoring the interface communication data of the Arinc 429 communication system. The system and method may achieve complete Arinc 429 communication system monitoring and hardware configuration recovery, rapidly and online eliminate restorable faults of the Arinc 429 communication system, position the faults of the Arinc 429 communication system in detail, enhance the reliability and the maintainability of the Arinc 429 communication system, and satisfy requirements of avionics system integration.

Description

technical field [0001] The present invention relates to an Arinc429 communication system self-inspection system and a self-inspection method, in particular to an Arinc429 communication system self-inspection system and a self-inspection method based on an integrated airborne collision avoidance system. Background technique [0002] TCASII is an integrated airborne collision avoidance system, which is mainly used to provide air safety separation guarantee for aircraft to achieve the purpose of collision avoidance. By inquiring, receiving, and processing the response signals of other aircraft's transponders, it monitors other aircraft around, and calculates the flight trend of other aircraft within the monitoring range relative to its own aircraft, and gives traffic warning and decisive warning suggestions. [0003] The TCASII airborne collision avoidance system itself has many functions, and the system composition is extremely complex. Among them, the Arinc429 communication s...
