Research and design of an intelligent monitoring system for HF receiving based on completeness

In order to realize the real-time and effective monitoring on the function completeness of complex short wave receiving equipment and accurately master the real working state of receiving system, a new intelligent monitoring system was designed. The receiving sensitivity and frequency accuracy index for the receiver, standing wave ratio (SWR) of the antenna-feeder system and the attenuation loss of the feeder are monitored. This paper made the analysis and improvement on traditional detection method, proposed the hierarchical architecture and system structure model of the monitoring system, designed a receiving monitoring terminal and audio monitoring terminal device based on remote network control, and gave a detailed description on the system's monitoring operation mechanism. Through coding and classification the monitoring state of receiving system, the improved multi-classification BP-AdaBoost algorithm is used to train and simulate the monitoring data, to realize the intelligent analysis of the monitoring state and the intelligent discrimination of the possible fault information, effectively improve the effectiveness and practicability of the monitoring system, and provide reference for the development and research of the related monitoring technology and methods.
