Embodiment Construction

[0008] Such as figure 1 As shown, the ADF642 compass, JZ-IAGPS receiver, and GPS150XL receiver are connected to the ADF / GPS comprehensive tester through the system interface, the signal generator is connected to the ADF462 compass through the antenna simulator, and the ARINC-429 interface board is connected to the comprehensive tester and the industrial computer respectively. , the industrial computer is connected to the display, and the computer detection part is the core of the test system of the present invention. It includes an ARINC-429 data interface board and an industrial computer, and mainly completes the real-time acquisition of the ARINC-429 signal output by the GPS receiver and the ADF compass. After processing and quantification, it will be displayed in specified physical units for interpretation by the inspector.

[0009] Such as figure 2 As shown, the system test software of the present invention includes four modules—system self-inspection, ADF-462 test, GPS1...

Abstract

A detection system is mainly composed of three parts with signal generator, system interface and computer detection, of which computer detection part is core of the detection system. The present invention can finalize collection and handling process of ADF data and GPS data as well as can make self-checking and period inspection for hardware of the detection system.

Description

technical field [0001] The invention relates to a comprehensive test system for an automatic guider and a global positioning system receiver on an aircraft. Background technique [0002] With the rapid development of avionics technology, the navigation and air positioning system, as an important part of the aircraft avionics system, is also developing rapidly. The automatic orientation system (ADF) can navigate according to the ground station (navigation station), and continuously and automatically indicate the heading angle. The global positioning system receiver (GPS) is composed of 24 satellites. It has high accuracy, fast positioning speed, good concealment performance, little impact on climate, simple equipment and low cost. Because ADF and GPS have good performance and superior performance-price ratio, they are widely used in modern aircraft, and there is no systematic automatic test equipment in China at present.
