1、基于数据采集卡的监控系统设计基于数据采集卡的监控系统设计The Design Of Monitoring System Based On Data Acquisition Card摘摘 要要船舶机舱监控系统是船舶自动化系统的重要组成部分。船舶机舱的自动化程度在某种程度上就代表了整个船舶自动化系统的先进程度。船舶机舱监控系统主要用于辅佐操作人员监控各项机组运行参数的变化情况,一旦发生异常,立即向操作人员发出警报,以便操作人员在第一时间检查警报信号发生处,并迅速做出处理,以减少非正常情况对船舶动力乃至整个船舶自动化系统造成的损害,从而大大降低船舶的损耗。一直以来,船舶成本低、高效益、无事故是机舱监
2、控的目的。因此,研究船舶机舱监控系统有很大的必要性和实用性。LabVIEW 作为编程语言,编程灵活高效且面对对象,其强大的图形编辑能力及可视化编程环境更是快捷简便;数据采集卡作为普遍使用的一种实现数据采集功能的计算机扩展卡,可以通过以太网、USB、火线(1394)等多种型号的总线接入计算机,使用方便。本文主要介绍了基于 LabVIEW 和数据采集卡的船舶机舱监控系统,该系统主要包括了用户登录、模拟量采集和开关量采集三部分,其中模拟量部分采集了温度、压力、电压等信号。系统监控了船舶运行时主柴油机、辅柴油机、电站、主锅炉和辅锅炉的多个相关量。关键词:关键词:LabVIEW;监控系统;船舶;机舱监控
