Embodiment Construction

[0008] like figure 1 As shown, the present invention includes a main control machine, a power supply unit, a signal control device I, and a signal control device II. The main control machine generates a digital signal and an analog signal and sends it to the control device. Simultaneously, the digital signal, the analog signal, and the switch The quantity signal is input to the EFIS system through the signal control device I and the signal control device II or the EFIS outputs the signal to the signal control device for measurement.

[0009] like figure 2 As shown, the main control computer performs the following operation steps: (1) The system performs self-inspection, turn on the computer, click the "EFIS" shortcut menu, the system performs self-inspection, if the self-inspection passes, the monitor will display a normal screen (without any information) ;(2) Test the air data of the electronic flight system, the 429 signals of TCN, LOC and ADF, and the synchronous signal o...

Abstract

A detector consists of main controller, power supply device, signal controll device I and signal control device II. The digital signal and analog signal generated by the main controller are transmitted to the control device and in the meantime, digital signal, analog signal and switching signal are inputted to EFIS system through signal control device I and II or outputting signal by EFIS to the signal control device for detection. The present invention utilizes industrial control computer as core integrated testing system to obtain complete display picture through simulating the operation state of EFIS on the aeroplane comprehensively.

Description

technical field [0001] The invention relates to a tester for an electronic flight instrument system. Background technique [0002] The electronic flight instrument system is a product imported from abroad, and it must be accurately tested when it is installed on the aircraft. At present, there is no localized electronic flight instrument system tester in China, and the foreign test equipment is comprehensive and expensive, so it is not applicable. Contents of the invention [0003] The purpose of this invention is to design a kind of electronic flight system comprehensive test equipment with industrial control computer as the core. [0004] The present invention is achieved in this way, it includes main control machine, power supply device, signal control device I, signal control device II, the digital signal and analog signal generated by the main control machine are sent to the control device, while the digital signal, a...
