Problems solved by technology

[0004] In view of this, the present invention provides a radio monitoring and direction-finding system, which realizes the direction-finding of radio signals by monitoring the signal received by the direction-finding host to the nine-unit direction-finding antenna, and realizes the direction-finding of the signal received by the omni-directional antenna by monitoring the direction-finding host The determination of the interference type of GSM-R is to improve the problem in the existing technology that it is difficult to identify and separate the same frequency, so as to determine the type of interference signal and the inaccurate radio signal direction finding

Embodiment Construction

[0013] To find sources of interference to radio signals, it is extremely important to determine the type and direction of the radio signal that is the interfering signal. Existing direction finding methods are usually unable to meet the requirements of co-frequency identification and separation when the interfered user’s communication is not allowed in the middle, using multi-base station transmitting equipment, or multi-point transmitting signals appear at the same frequency at the same time, and determine the type of interfering signal and the source of the signal. direction.

[0014] In view of the above situation, the inventor provides a radio monitoring direction finding system to improve the existing problems after long-term research and a lot of practice. The monitoring and direction-finding host of the radio monitoring and direction-finding system analyzes and processes the signals received by the nine-unit direction-finding antenna and the omni-directional antenna res...

Abstract

The embodiment of the invention provides a direction-finding system for radio monitoring. The system comprises an omni-directional antenna, a one-to-three power divider, a nine-unit direction-finding antenna, a nine unit signal switching module and a monitoring direction-finding host. The nine-unit direction-finding antenna and the nine-unit direction-finding antenna are in signal connection; the nine-unit direction-finding antenna and the monitoring direction-finding host are in signal connection; the omni-directional antenna is connected with an input port of the one-to-three power divider; and a plurlaiyt of output ports of the one-to-three power divider is connected with the monitoring direction-finding host.

Description

technical field [0001] The invention relates to the field of radio direction finding, in particular to a radio monitoring and direction finding system. Background technique [0002] GSM-R (Global System for Mobile Communications-Railway) system is a comprehensive dedicated digital mobile communication system specially designed for railway communication. GSM-R is a kind of dedicated mobile communication, dedicated to the daily operation and management of railways. [0003] With the development of my country's radio industry, radio spectrum resources are becoming increasingly tight, and radio interference incidents are increasing. Especially in recent years, with the rapid development of high-speed rail technology, GSM-R communication interference occurs from time to time. It is becoming more and more important to find and locate interference sources and to find the direction of the radio through radio monitoring and direction finding, so it is necessary to monitor or find the...
