Embodiment Construction

[0063] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0064] As mentioned above, analog walkie-talkies are gradually being replaced by digital walkie-talkies. In order to strengthen the supervision of digital walkie-talkies, it is imminent to develop a monitoring system for digital walkie-talkies. In order to solve this technical problem, the embodiment of the present invention also provides a walkie-talkie monitoring system, which can expand the analysis function of the existing radio...

Abstract

The invention provides a walkie-talkie monitoring system. The system includes: an antenna, a radio frequency front end, a signal processing unit, and a user interface unit, wherein the antenna is used to obtain the radio frequency signal of the walkie-talkie to be monitored; the radio frequency front end is used to perform preset processing on the obtained radio frequency signal to obtain an intermediate frequency signal; the signal processing unit is used to perform analog-to-digital conversion on the intermediate frequency signal, and perform FFT calculation and demodulation and decoding processing, or IQ data recording, to obtain spectrum processing data and decoding data, or IQ data; the user interface The unit is used to display the spectrum in real time according to the spectrum processing data and decoding data, or store the IQ data for export for subsequent analysis, so as to realize the monitoring of the walkie-talkie. The invention expands the analysis function of the existing radio platform for the signal of the digital walkie-talkie, can display the frequency spectrum monitoring result in real time, and has the monitoring function of the analog walkie-talkie at the same time.

Description

technical field [0001] The invention relates to the technical field of radio monitoring, in particular to a walkie-talkie monitoring system. Background technique [0002] Walkie-talkies are widely used in many industries and fields because of their instant communication and free calls. At present, there are two main types of walkie-talkies: analog walkie-talkies and digital walkie-talkies. The digital walkie-talkie is a walkie-talkie designed with digital technology, which digitizes the voice signal and transmits it in the form of digital code, thus greatly improving the call quality and frequency utilization. With the development of radio communication technology, the improvement of wireless communication quality and the increasing demand for spectrum resources, digital walkie-talkies have attracted more and more attention. With the development of digitization, analog walkie-talkies are gradually being replaced by digital walkie-talkies. According to the documents of the...
