Intelligent shortwave receiving monitoring system based on receiving function completeness

Abstract

The invention discloses an intelligent shortwave receiving monitoring system based on receiving function completeness. The monitoring system is characterized by comprising a monitoring emitter mounted outside a receiving antenna field, wherein a receiving monitoring terminal is mounted on a receiving antenna feeder to be monitored; a receiver and a standard monitoring receiver are connected with the receiving monitoring terminal through an antenna exchanger; an audio monitoring terminal is mounted at an audio output terminal of the receiver; a monitoring server is connected to the standard monitoring receiver; data of the audio monitoring terminal and the standard monitoring receiver is transmitted to the monitoring server; and a receiver working parameter acquisition subsystem acquires the data from the monitoring server to carry out computation and analysis. The monitoring system provided by the invention has the advantage that the radio frequency sensor technology and the network automatic control technology are comprehensively used to construct a monitoring system model for the function completeness.

Description

Technical field [0001] The invention belongs to the field of shortwave communication monitoring, and particularly relates to a shortwave reception intelligent monitoring system based on the completeness of the reception function. Background technique [0002] In the use of short-wave communication, due to the high output power and high power consumption of the sending equipment, the possibility of failure and abnormality is greater. Therefore, users usually pay more attention to the sending equipment and perform regular maintenance and performance testing. ; And because of the low power consumption of the receiving equipment, the working status and stability are much better than that of the sending equipment, which leads to insufficient attention to its daily inspection and maintenance. With the increase of use time, the receiving equipment will inevitably appear Some performance degradation or lack of completeness of functions also require users to have a timely and accurate gra...

AI Technical Summary

Problems solved by technology

However, in the process of daily use and maintenance in the later stage, factors such as poor contact caused by long-term use wear or the substandard welding process of the feeder and RF connectors will cause the loss of the antenna feeder to be too large, exceeding the design and demand range.

This will cause the electromagnetic signal induced on the antenna to be greatly attenuated during the transmission of the feeder, so that when it reaches the receiver, it cannot meet the requirements of receiving sensitivity and cause adverse effects on the receiving effect

The attenuation loss of the feeder can also be tested with the antenna feeder tester, the figure 2 The attenuation loss can be measured by removing the antenna in it. The advantages and disadvantages of this method are similar to those of the standing wave ratio test method
