【摘要】 本文设计了一种基于CAN总线的智能火灾监控系统。运用单片机技术、现场总线技术与模糊控制技术进行优化。该系统可实现在线检测，可不间断地通过液晶屏显示用电线路的工作电流，漏电电流，以及环境温度等参数。通过本系统能随时掌握电气线路或设备的火灾危险参数的变化情况、故障和异常状态。并且能够及时发现火灾隐患，通过声光报警以及联动装置消除火灾隐患。论文对基于CAN总线的火灾监控系统进行了深入分析和研究。在查阅了智能火灾报警系统的发展情况的基础上进行了系统方案设计，论文详细描述了系统硬件、软件和算法的设计。论文描述的硬件设计包括系统总体结构以及区域火灾监控系统的结构及功能设计。软件设计包括区域火灾监控系统软件设计与上位机MCGS系统组态，软件设计采用了由顶向下的设计方法，完成了区域火灾监控系统软件的功能设计并给出了程序流程图。在智能算法设计中探讨了一种基于模糊控制的智能算法。算法结合模糊控制的特点，使用模糊控制规则对各传感器采集的信号进行处理，而后经过模糊判决发出报警信号。本文对系统的可靠性和实时性进行了分析，其测试结果表明可以达到国家规定的要求。本系统具有智能化和高可靠性等特点，但是还有一些环节有待进一步完善，所以文章的最后对智能火灾报警系统的发展作了展望，并提出了系统改善的一些具体方法。更多还原

【Abstract】 This thesis has designed a kind of intelligent fire alarm system base on CAN bus. With LCD screen displaying the operating current, the leakage electric current, and the environment temperature, this system can realize the online examination, Through this system, we can get the status of the electrical line, the fire risk of the equipment, and the abnormal state as necessary . Through the alarm signal sent by the sound and the light alarm device, the system can discover the fire hidden danger promptly. And the system used the excute device eliminating the fire hidden danger.This thesis has made an in-depth analysis and research in the fire supervisory system based on the CAN bus. After consulted the fire supervisory system development situation, this thesis designed the system. This thesis has descriped hardware, software and the algorithm design in detail. The hardware design included the system structure design as well as the region fire supervisory system structure and the functional design. The software design included the region fire supervisory system software design and the industry control computer MCGS system configuration, it has completed the region fire supervisory system software functional design and has given the program flow diagram. The intelligent algorithm design discussed one kind intelligent algorithm based on the fuzzy control.This algorithm unified the fuzzy control characteristic, and used fuzzy control rule processing the signal which gathered from various sensors, and then passed through the fuzzy judgment,at last send out the alarm signal.Finally,this thesis analysis the reliability and timeliness of the system, the test result had indicated this system could achieve the national stipulation the request. It has some flaw, therefore the thesis finally has made the forecast to the intelligent fire alarm system development, and proposed some methods to improve system.更多还原
