Abstract

The invention relates to a tester for an over-the-air broadcasting device, and belongs to field of ground test for airborne equipment. When the over-the-air broadcasting device is mounted, a plane need to electrify the device to verify whether functions of the device are normal; however, the over-the-air broadcasting device electrified for a long time tends to damage hearing of people nearby due to the high output power. The tester provided by the invention can detect all the function of the over-the-air broadcasting device in a lab, as well as detect functions on a control box or loudspeaker independently.

Description

An air broadcast equipment tester

technical field

The invention belongs to the field of ground testing of airborne equipment, in particular to an air broadcasting equipment tester.

Background technique

The air broadcasting equipment of the aircraft is not a necessary equipment for flight, and it does not affect the safety of flight. Its function is for the personnel on the aircraft to shout to the ground personnel when the aircraft is in the air, and to play the role of commanding, announcing, and driving away. Therefore, air broadcast equipment is an optional equipment, and because of its seldom application, there is almost no special equipment for its detection at present.

After the air broadcast equipment is installed, the aircraft needs to be powered on on the ground to verify whether its function is normal, but the output power of the air broadcast equipment is relatively large, and it is easy to damage the hearing of nearby personnel if it is powered on for a long time.

Contents of the invention

The technical problem to be solved by the present invention is to provide an air broadcast equipment tester for testing the air broadcast equipment in a laboratory.

The aerial broadcasting equipment tester of the present invention comprises the interface connected with the airborne control box of the airborne broadcasting equipment, and the side-tone output terminal, voice input terminal, lighting switch, PTT switch, power supply and loudspeaker connected with the interface, through the The voice input terminal provides voice input to the airborne control box and broadcasts through the speaker, and provides voice signals through the side-by-side output terminal; there is a terminal for extracting audio signals in the connection cable between the interface and the speaker, which can be broadcast by an external speaker monitor or connect a load to an analog loudspeaker for analog monitoring.

Further, the power supply has a power switch, and the power switch includes a switch and a fuse to ensure the safety of power supply.

Further, the lighting switch includes a switch and a rheostat to control the brightness of the lighting of the air broadcasting equipment control box.

The beneficial effect of the invention is that: the air broadcasting equipment can carry out a whole set of functional testing in the laboratory, and can also perform functional testing on the control box or the loudspeaker separately.
