Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, a radio compass tester of the present invention is composed of a DC power supply circuit 1, an AC power supply circuit 2, an audio output test interface 3, a synchronous output test interface 4, and a tester main body 5. The connector is connected with the wireless electromagnetic indicator 6, the converter 7 and the compass receiver 8 of the radio compass system, and the compass receiver 8 is connected with the antenna 9 and the power adapter 10. The following are the introduction of the signal transmission and the functional test of the system:

[0017] The DC power supply circuit 1 connects the DC 28V to the wireless electromagnetic indicator 6 and the compass receiver 8 respectively through the interface of the main body 5 of the tester, and the DC power connected to the compass receiver 8 converts the DC 28V into the compass recei...

Abstract

The present invention provides a radio compass tester, and relates to radio compass system testing. The radio compass tester comprises a direct current power supply circuit, an alternating current power supply circuit, an audio frequency output testing interface, a sync output testing interface, and a tester main body, wherein the direct current power supply circuit is connected with the tester main body, the direct current power supply circuit is used for inputting 28 V direct current to the tester main body, the alternating current power supply circuit is connected with the tester main body, the alternating current power supply circuit is used for inputting 26 V/400 Hz alternating current to the tester main body, the tester main body is respectively connected with a radio magnetic indicator, a converter and a compass receiver, the audio frequency output testing interface is connected with the tester main body, and the sync output testing interface is connected with the tester main body.

Description

technical field [0001] The invention relates to a radio compass system test, in particular to a radio compass tester. Background technique [0002] The radio compass is the main product of the aircraft radio navigation system. It is mainly composed of a compass receiver, a control box, a loop antenna, and a wireless electromagnetic indicator. And local civil broadcasting stations can easily measure the relative orientation of the aircraft and the ground navigation station, so as to realize the navigation for the aircraft. [0003] At present, there is no corresponding supporting special tester for calibration. Simple testing through the existing test connection cannot meet the requirements of the pre-installation calibration of the finished product and cannot guarantee the quality of the installed product. Contents of the invention [0004] Purpose of the present invention: provide a kind of radio compass tester, can finish the test to the various performances of radio co...
