摘 要
船舶延伸报警系统是实现无人机舱的关键技术,是船舶机舱监测报警系统的重要组成部分,是实现自动化和智能化的关键系统之一。无人机舱目前已经成为新造船舶的常规要求。在无人值班时,一旦运行设备发生故障,监测报警系统自动将声光报警信号发送至延伸报警系统,延伸报警系统将报警信号及时有效的延伸到驾驶室、公共场所、轮机长和值班人员住所。
本文首先介绍了现阶段国内外船舶延伸报警系统的发展状况,简要分析了船舶机舱监测报警系统组成功能和基本原理,随后研究了现有的延伸报警系统的组成方式,分析了现有的延伸报警装置的优缺点,并在此基础上,提出了一套通用性能好、可靠性高、功能齐全的延伸报警系统设计方案。在研究了应用于船舶监控领域的通信技术后,延伸报警主从装置之间通过以太网、CAN或RS485等方式实现通信,共同组成系统,实现报警信号的有效传输。本文的侧重点是实现以太网传输。
本设计采用C8051F340为控制器核心,重点在单片机上实现了uIP协议的移植,实现了以太网的传输,并完成了CAN和RS485通信。随后,介绍了基于单片机的延伸报警装置的硬件电路设计方法,包括电源部分、报警显示部分、值班人显示部分、液晶显示部分、开关量输入部分以及通信模块部分等。由于延伸报警系统应用于船舶这样一个相对特殊的环境,所以本文对系统的抗干扰性能进行了详细的讨论,分析了在电路设计、PCB设计过程中的一些提高抗干扰性能的措施。
在完成硬件电路设计后,本文介绍了系统的软件设计方法,详细介绍了uIP协议在单片机上的移植方法,以太网控制器ENC28J60对数据发送和接收的流程。随后介绍了延伸报警装置主从机的软件设计流程,并对延伸报警系统的整体调试过程和结果作了介绍。
最后,对系统设计与论文作了总结并且对系统的应用前景和一些可以改进的地方进行了展望。

Abstract
The ship extended alarm system is the key technology of the realization of unmanned engine room. As an important part of the monitoring and alarm system, it is the most critical to the engineering automation and intelligent. Now unmanned engine room has become the general requirement of the new building ships. In the circumstances of unmanned engine room, once the equipment fails, it can send out acousto-optic alarm signal automatically, extend the alarm signal to the bridge, public sites and the accommodations of the chief engineer and other engineers.
This paper firstly introduces the development of domestic and foreign ship extended alarm system and then analysises the constitution and function. On the basis of researching on system’s advantages and disadvantages of the existing extended alarm system, the author gives a general, realiable and functional design scheme. After introducing the communication’s technology used in the ship monitoring and alarm field, the extended alarm master device and slave devices communicate by ethernet, CAN bus and RS-485. Our design emphasises on the ethernet communication.
This design uses the C8051F340 micro-processor as the core and focuses on the transplantation of network communication uIP protocol stack. As the same time, the CAN bus and RS-485 are also considered. Then, the hardware design methods of the extended alarm system are given which include the power unit, alarm display unit, on duty display unit, LCD display unit, switch input unit and communication unit. Because the extended alarm system is used in special environment, the article discusses the anti-interference performance of the system in detail and analysises the measures of reducing interference which are used in the circuit and PCB design.
After the hardware design, this paper introduces the methods of software design especially the transplantation method of uIP protocol stack and the data sending and receiving process which is based on the embedded network control chip ENC28J60. Then the paper gives the software process flow of the extended alarm master and slave devices. And the integrated debugging process and results of the extended alarm system are also given.
At last, the author summarizes the system designment and the paper, look forward to the system’s application and some improvements.
