Short-wave transmitting intelligent monitoring system based on completeness of transmitting function

Abstract

The invention discloses a short-wave transmitting intelligent monitoring system based on completeness of a transmitting function. The system comprises a transmitting radio frequency monitoring terminal, an electric power monitoring terminal, a broadband monitoring antenna and a comprehensive monitoring platform; the transmitting radio frequency monitoring terminal is arranged to acquire transmitting power, frequency, modulation degree and standing-wave ratio data of a short-wave transmitter radio frequency transmission cable and an antenna feeder system; the electric power monitoring terminalis arranged to acquire alternating voltage and current data of the short-wave transmitter; the broadband monitoring antenna module is arranged to measure a space electromagnetic signal radiated by a transmitting antenna of the short-wave transmitter and calculate actual output power data of the transmitting antenna; and the comprehensive monitoring platform performs analysis, calculation and evaluation according to the received acquired data of the transmitting radio frequency monitoring terminal, the electric power monitoring terminal and the broadband monitoring antenna module. Therefore, the working state of the transmitting antenna of the short-wave transmitting system, the radio frequency loss attenuation condition between the short-wave transmitter and the transmitting antenna, the matching state of the transmitting antenna and the radiation state of the transmitting antenna field are monitored in real time.

Description

technical field [0001] The invention belongs to the field of short-wave signaling, and in particular relates to an intelligent monitoring system for short-wave signaling based on the completeness of signaling functions. Background technique [0002] The short-wave signaling system refers to the electronic system that undertakes short-wave communication transmission tasks. It is generally composed of a transmitter, a computer room, a central control room, a signaling antenna, a feeder system (including antenna switching equipment), signal line equipment, and a high-frequency grounding device. . For a long time, many short-wave communication stations have been distributed in mountainous areas or outer suburbs, with remote areas and inconvenient transportation. Moreover, there are many types of short-wave communication equipment in the stations, and the number is large and the installation is fixed. Therefore, in order to ensure the normal development of short-wave communicatio...
