Air traffic control voice multi-channel automatic test system

Abstract

The invention provides an air traffic control voice multi-channel automatic test system. The system comprises a hardware control box, test software, a radio comprehensive tester, an interface card anda test computer. The test computer is provided with application software and a radio comprehensive tester driving program. By means of an advanced R&S CMA180 radio comprehensive tester and matched software and hardware which are independently researched and developed, the system can be applied to automatic testing of voice channels of equipment such as an air traffic control interphone and avery high frequency radio station, breaks through a limitation that conventional voice testing mainly aims at a single seat, a single channel and single equipment, can be expanded to 10 channels to the maximum extent, reduces human intervention, and improves test accuracy, reliability and working efficiency. Configuration can be selected according to equipment characteristics, more abundant test means are provided, safe and reliable operation of the air traffic control ground-air communication equipment is effectively guaranteed, and a high application value and economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of reliability automatic testing of civil air traffic management ground-air communication system equipment, in particular to an air traffic control voice multi-channel automatic testing system. Background technique [0002] At present, for the test method of civil aviation control voice switching system (internal phone system), usually the simplest test method is: through the control seat interface of the voice switching system, select the corresponding radio channel, artificially use the audio meter or radio comprehensive test Instruments, headsets, and radio voice interfaces to detect whether the transmitted and received voices are normal, the audio amplitude, whether the PTT button is triggered normally, whether there is mute or noise, etc., but such manual testing methods are extremely inefficient. [0003] For the test method of air traffic control VHF system, the radio comprehensive tester is usually u...

Problems solved by technology

In addition, during the test, when a failure is found, it is necessary to clearly record and identify the corresponding cause of the failure. If there is a mistake in the manual operation record, it will cause errors in the recorded data, which is not conducive to the later failure statistics and maintenance.

[0004] The traditional interphone and VHF equipment voice test is mainly for single seat, single channel, and single device, using radio comprehensive tester or audio meter to measure related parameters, all instrument operations and data records must be manually performed, which takes a long time , low efficiency, heavy workload, and prone to errors and mistakes

Since the equipment of the civil air traffic control communication system operates continuously for 24 hours without stopping, the requirements for system reliability are very high. Therefore, there has been a lack of effective methods and means, especially in multi-channel and long-term testing.
