Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a radio signal monitoring device for civil aviation. Background Art

[0002] Radio signal is the general term for original signal and modulated oscillation signal. The information to be transmitted, such as sound, image, text, code, etc., is converted into corresponding voltage or current after passing through the conversion equipment. This changing voltage or current is called original signal. The original signal modulates high-frequency oscillation in the transmitter, or controls a certain parameter of high-frequency oscillation, so it is also called modulated signal or control signal. Modulated high-frequency oscillation, or high-frequency oscillation whose parameters change according to the law of modulation signal, is called modulated oscillation, also called modulated wave. Radio signals can interfere with the flight of aircraft, so in order to prevent aircraft from being interfered with, most civil aviation airports will install radio signal monitoring devices to monitor the radio signals around civil aviation airports. Traditional monitors cannot adjust the angle for use. In order to improve this situation, a radio signal monitoring device for civil aviation is proposed.

[0003] As disclosed in the authorization announcement number CN108134638B, a multi-channel radio signal monitoring device includes a multi-channel ADC module, an ADC channel selection module, a multi-channel orthogonal mixing module, a DDC multi-stage extraction filter module, a bandwidth selection module, a channel arbitration module and a multi-mode audio demodulation module which are electrically connected in sequence, and also includes a spectrum calculation module connected to the output end of the channel arbitration module and an ITU parameter measurement module connected to the output end of the spectrum calculation module, and the input end of the multi-channel ADC module receives a multi-channel intermediate frequency analog signal;

[0004] Although it can simultaneously monitor and analyze multiple narrowband signals within the intermediate frequency bandwidth, it is very flexible and practical, greatly reduces resource utilization, solves the bottleneck of multi-channel monitoring engineering implementation, and has high engineering practical value, but it does not solve the problem that the existing monitoring devices are not conducive to convenient angle adjustment and convenient movement adjustment of height during use, and are not conducive to circular rotation adjustment, which affects the monitoring effect and flexibility of use.
