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 an interphone monitoring system. The system comprises an antenna, a radio frequency front end, a signal processing unit and a user interface unit; the antenna is used for acquiring a radio frequency signal of an interphone to be monitored; the radio frequency front end is used for performing preset processing on the acquired radio frequency signal to obtain an intermediate frequency signal; the signal processing unit is used for carrying out analog-to-digital conversion on the intermediate frequency signal, and carrying out FFT calculation and demodulation decoding processing, or IQ data recording to obtain frequency spectrum processing data and decoding data, or IQ data; and the user interface unit is used for displaying the frequency spectrum in real time accordingto the frequency spectrum processing data and the decoding data, or storing the IQ data for exporting and carrying out subsequent analysis, thereby monitoring the interphone. The digital interphone signal analysis function of an existing radio platform is expanded, the frequency spectrum monitoring result can be displayed in real time, and meanwhile the analog interphone monitoring function is achieved.

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...
