Frequency spectrum automatic monitoring analyzer for satellite ground station intermediate-frequency signal

Abstract

The invention relates to a frequency spectrum automatic monitoring analyzer for a satellite ground station intermediate-frequency signal. The frequency spectrum automatic monitoring analyzer consists of a frequency spectrum information acquisition module, a cabinet and a power supply, wherein the frequency spectrum information acquisition module consists of a frequency spectrum information acquisition card, a state indication panel, a shielding shell and a sliding rail; and the frequency spectrum information acquisition card consists of hardware and singlechip software, is provided with an intermediate-frequency signal input interface, a communication interface and a power supply interface and has functions of repeated mixing, filtering change-over, logarithmic transformation, amplification, analog / digital (A / D) conversion and serial port communication. By the automatic monitoring analyzer, required frequency spectra can be measured by using one special intermediate-frequency frequency spectrum information acquisition module; the measurement range of the frequency spectra can be expanded by increasing the number of frequency spectrum acquisition modules; and the seamless automatic monitoring and real-time alarming of network-wide frequency resources of a satellite communication network is realized by utilizing a computer network technology, a database technology and a software technology so as to improve communication quality.

Description

Technical field: [0001] The invention relates to a monitoring device for frequency resources of a satellite communication network, in particular to an automatic monitoring analyzer for an intermediate frequency signal spectrum of a satellite ground station. Background technique: [0002] In the field of satellite communication, the spectrum analyzer is an important instrument for spectrum measurement. In almost all satellite communication networks, the spectrum analyzer is the main means of frequency resource monitoring. It has high measurement accuracy, high resolution, wide measurement range, convenient use and It has been widely used due to its reliable performance. However, in the actual measurement process of existing spectrum analyzers, one spectrum analyzer can only manually measure or monitor signals in a certain frequency band under any circumstances. spectrum analyzer to complete.

However, in the actual measurement process of existing spectrum analyzers, one spectrum analyzer can only manually measure or monitor signals in a certain frequency band under any circumstances. Spectrum analyzer to complete

And if you want to monitor multiple signals at the same time for a long time without interruption-this is almost impossible. The reason: not only because the spectrum analyzer is expensive, a large number of configurations are expensive, but also many skilled Even so, it can only be monitored manually, not automatically, and the adequacy and reliability of its monitoring are affected

This is a weak link in the current satellite communication network frequency resource monitoring, and it is also a lagging point in this technical field
