摘要
为了提高船舶机舱的延伸报警安全性和互联通信可靠性及实时控制性,文中提出基于LPC1768为核心采用CANopen通信协议的机舱延伸报警系统,可以进一步提高系统的可靠性、通信效率及灵活性。系统采用模块思想设计,实现了主站人工、自动切换,系统运行状态自我监测,运行状态显示和声光报警等功能,阐述了系统硬件设计、CANopen协议软件的实现过程(包括节点的对象字典和通信模型建立)。结果表明该系统能够准确侦听报警信息,且结构简单。能够满足船舶延伸报警的要求、提高了延伸报警的可靠性和兼容性。
To improve the ship cabin extension alarm security and Internet communication reliability and actual time controllability, This thesis is an auto extended alarm system was designed based on NXP LPC1768 with CANopen protocol, can further improve the system reliability, communication, efficiency and flexibility. The system is based on m0dules,the software was designed to realize the functions of main control unit auto/manual-switching,self-monitoring system running status, operating status display audible and visual alarm functions of the system hardware design, the implementation process of the CANopen protocol software （including the object dictionary and communication model）. The results show that the system be able to accurately listener alarm information, and the structure is simple, Able to meet the requirements of the ship extending alarm, improve extended alarm reliability and compatibility.
