Wireless spectrum interference monitoring system and method for low-frequency time code monitoring system

Abstract

The invention discloses a wireless spectrum interference monitoring system and method for a low-frequency time code monitoring system, and the system comprises an antenna module which is used for carrying out the omnidirectional receiving of an electromagnetic interference signal in a surrounding environment of the low-frequency time code monitoring system for a preset monitoring frequency band; afrequency spectrum acquisition module which is used for amplifying the signal received by the antenna module, sampling the signal, and filtering to obtain the power and frequency point of each signalin a preset monitoring frequency band; a data analysis module which is used for inputting the signal power acquired by the frequency spectrum acquisition module to realize power value statistics of interference signals and research and judgment of the interference signals; and a support module which is used for providing power supply and rack support for the wireless spectrum interference monitoring system. By setting the relative reference value and the statistical signal change trend, wireless spectrum interference monitoring in a low frequency band can be realized.

Description

technical field [0001] The invention belongs to the field of radio communication technology and signal measurement technology, and relates to wireless spectrum interference monitoring, in particular to a wireless spectrum interference monitoring system and method for a low-frequency time code monitoring system. Background technique [0002] Wireless spectrum monitoring is the foundation and core function of wireless spectrum management. Only when accurate, detailed and timely wireless spectrum monitoring is established can wireless spectrum management be scientific and effective. For the low-frequency time code monitoring system, the main purpose of setting up wireless spectrum interference monitoring is to collect, process, analyze and mine the information of all signals in the low-frequency band without loss or distortion, so as to realize Each dimension monitors the complex electromagnetic environment, and has the functions of predicting and alarming sudden interference a...

Problems solved by technology

Since the signal power or field strength is related to the transmitting power of the transmitter, when the receiving end is at different distances, the measured signal power is different; in addition, when the monitoring environment changes, the measured signal power is also different, and the threshold value needs to be adjusted at any time. Make adjustments to bring inconvenience to the signal monitoring work
