基于RS—232串行通信的监控系统数据信息提取共享设计

文章针对某新型舰的动力系统在数据信息监测共享上的缺陷,提出了一种利用RS—232串行通信端口实现数据信息提取共享的方案,它充分利用传统串行接口的优势,采用轮询的方式实现串行通信,实现了实时控制通信和数据传输校验功能,并给出了硬件设计电路、软件设计流程图和设计方法。实验结果表明,采用文中给出的设计是可行的;系统在实时性、准确性上都达到良好效果,实现了集控室监控系统数据提取共享的功能,并满足便捷、经济的要求。

To overcome the shortcomings on shared data information monitoring in a new-type marine power system, this paper puts foward a shared plan extracted from data information on the end of RS - 232 serial communication. With the virtue of the traditianal serial interface, serial communication by polling, real-time controlling communication and data transforing checking function are realized. Hardware-designing circuit, software-designing flow chart and designing methods are also given. Experiments prove the design feasible, with good efficiency on real-time and accuracy. Thus, shared data from monitoring system meets the needs of the requirement on convenience, quickness and economization.
