This thesis has designed a kind of intelligent fire monitoring system, using the mcu technology, field bus technology and fuzzy algorithm. 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.Firstly, This thesis has made an in-depth analysis and research in the fire monitoring system. After consulted the fire supervisory system development situation, this thesis designed the system.Secondly, the hardware, software and the algorithm is designed in detail. The hardware design included the system structure design as well as the region fire supervisory system structure and the functional design.Thirdly, the software design included the region fire supervisory system software design, it has completed the region fire supervisory system software functional design and has given the program flow diagram.Finally, The intelligent algorithm design discussed one kind intelligent algorithm based on the fuzzy algorithm. This algorithm unifies the fuzzy arithmetic 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.This thesis analyzes the reliability and timeliness of the system, the test result had indicated this system could achieve the system 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.
