Anti-jamming Design of Abnormal Data Acquisition Terminal Metering in Power Supply Station under Attenuation Compensation
The current anti-jamming method for abnormal data acquisition terminal metering in power supply stations is easily affected in face of pulse or narrowband interference.Especially in the presence of mixed interference,traditional methods have great limitations.In order to solve the problems,a new anti-jamming analysis method of the abnormal data acquisition terminal measured by the power supply station is proposed through attenuation compensation analysis.This paper establishs the attenu-ation compensation topology,calculates the current of the parent node in the power line,uses the waveguide compensation method to realize the compensation of the optical fiber attenuation environment,determines the pheromone concentration be-tween nodes through the heuristic factor,and uses the direction factor and the ant colony algorithm to establish the anti-jam-ming system of abnomal data acquisition terminal.The signal acquisition device in the data acquisition terminal completes the monitoring and input of abnormal data,and realizes anti-interference analysis.The experimental results show that the proposed method can reduce the loss through mixed interference analysis,prevent more than 99％of the interference information,and improve the anti-interference ability of abnormal data.
