摘　　要：本文根据广东卫星地球站自身发展的客观情况和需求,自主开发卫星信号频谱监测报警系统。通过python编程语言实现高效系统开发,对线程的休眠时间进行测试,选择合适线程休眠时间(300ms)提高程序的运行速度和性能;对三种图像模板匹配算法进行测试比对,在匹配准确率相同的情况下,采用耗时最短的“标准差值平方和匹配算法”对数字进行识别;通过节点之间的关联依赖,判断故障根源;使用MySQL数据库方便数据的记录和查询。利用各种技术和方法来确保系统的高效运行,满足业务需求,为保障安全播出提供支撑。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.
