Description
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.
Therefore, the present invention can perform real-time monitoring of the output signals of the ARINC 429 generated by the FLCC by performing an integration test on the ARINC 429 communication interface, which can be provided in the FLCC, while maintaining the existing integrated test environment for the FLCC To provide an integrated test system for the ARINC429 communication interface.
In order to achieve the above object, an integrated test system of the ARINC 429 communication interface according to an embodiment of the present invention is connected to an ETS (Engineering Test Station) having no ARINC 429 communication interface, An integrated test host system, an ARINC429 emulator, and an ARINC429 interface box, the integrated test system of the ARINC429 communication interface enabling testing of each of the ARINC429 communication interfaces of computers (Flight Control computers: FLCCs) The apparatus provides the ARINC 429 signal generation commands to the ARINC 429 emulator so that all the sensor signals of the aircraft or the weather related information of the outside air in the ARINC 429 emulator can be generated in the form of ARINC 429 signals and the ARINC 429 emulator As an integrated test host device And the ARINC 429 interface box is connected to the ETS, and the ARINC 429 signals output from the ARINC 429 emulator are connected to the ETS through the ETS, The ARINC 429 emulator receives the ARINC 429 output signals generated and output from the FLCCs through the ETS and the ARINC 429 interface box and transmits the ARINC 429 output signals to the integrated test host device And the integrated test host device monitors the ARINC 429 output signals provided from the ARINC 429 emulator.
