Description

{INTEGRATION TEST SYSTEM FOR ARINC429 COMMUNICATION INTERFACE}

The present invention relates to an integrated test system of the ARINC 429 communication interface, which performs an integrated operation test on a system having an ARINC 429 communication interface, such as aviation, and real time monitoring of the generated ARINC 429 signal .

In general, the flight control system controls the attitude, speed, etc. of the aircraft according to the instructions of the aviator or the flight control computer or the flight control computer (FLCC), enabling manual and automatic steering. Such a flight control system is composed of hardware such as a computer, a database, a detector and an actuator, and a software such as mode management, self diagnosis, fire control, and path control. In particular, introduction of a digital computer, which has been continuously improved in performance in spite of miniaturization, has led to a breakthrough in flight control, making it possible to fly precisely and steerably so that it can not be imagined.

On the other hand, the flight control system is a safety-oriented system that can affect aircraft and pilot safety. Therefore, the FLCC, which is a core system of helicopter, acquires various sensor signals and weather information related to the outside air to perform airplane management for safe flight. Therefore, it is necessary to monitor in the integrated test environment whether the FLCC performs normal operation before the aircraft is finally developed. And, if it is confirmed that the FLCC operates normally in the integrated test environment, the ground and flight tests can be performed, and the safety of the aircraft flight control system can be verified.

In recent years, the FLCC has been designed to output an ARINC 429 driving signal for an electro-mechanical actuator (EMA) provided on an aircraft, having an ARINC 429 communication interface. Therefore, monitoring of whether an FLCC with an ARINC 429 communication interface in the integrated test environment prior to ground and flight tests on an aircraft generates and provides a normal ARINC 429 output signal according to an external input signal needs to be performed.

However, the test environment for the ARINC429 communication interface, which can be installed in the FLCC, is not provided in the integrated test environment for the currently constructed FLCC.
