Design and Application of Satellite Signal Spectrum Monitoring and Alarm System
According to the objective situation and demand of Guangdong Satellite Earth Station's development,this paper independently develops a satellite signal spectrum monitoring and alarm system.An efficient system is developed through using Python programming language,the thread sleep time is tested,appropriate thread sleep time(300ms)is selected to improve program running speed and performance,and three image template matching algorithms are tested and compared.At the same time,the shortest time consuming"standard difference sum of squares matching algorithm"is used to recognize numbers with the same matching accuracy,the root cause of the fault is determined through the correlation dependency between nodes,MySQL database is used to facilitate data recording and querying.In addition,various technologies and methods are utilized to ensure the efficient operation of the system and meet business needs,providing support for ensuring safe broadcasting.
