文档介绍:火灾报警系统设计
摘要
火灾已成为我国常发性和破坏性以及影响力最强的灾害之一。随着经济和城市建设的快速发展,城市高层、地下建筑以及大型综合性建筑日益增多,火灾隐患也大大增加,火灾的数量及其造成的损失呈逐年上升趋势。在工业和民用建筑、宾馆、酒店、图书馆、科研和商业部门,火灾报警系统已成为必要的装置。火灾报警系统对现代建筑起着极其重要的安全保障作用。火灾报警控制器是火灾报警系统的核心。本文对火灾报警控制器和探测器做了深入的研究,并全面阐述了火灾报警控制器和探测器硬件和软件设计。以下是本文完成的主要工作:
,所设计的控制器具有较高的性价比,还具有操作人员管理、报警信息查询、探测器管理、预报警、火警处理、通讯等功能,在控制器中采用LCD显示器进行报警系统所需各种信息显示。
,它实现了对火灾信息的检测和传送;为提高系统的适应性与扩展性,进行了写码器设计。
,运用 KB8825双频合成器进行了无线通讯电路设计,具有抗干扰能力强、功耗低等优点,可靠地完成了探测器与控制器之间的无线通信。
本文设计的火灾报警系统能有效地防止和减少火灾危害,解决有线火灾报警系统不能解决的问题,对保护人身安全和财产安全具有现实意义。

Abstract
In our country, as a disaster, the fire has many characteristics, such as: mediocrity, breakage and influence. In recent years, the economy and the construction develop quickly, increasing of modern building, underground architecture and large-scale construction, the occasion of fire is increasing, the quantity of fire and the losing it leads to raise gradually, the intention of fireproofing is avoiding loss. In the instruction of industry and civil, hotel, grogshop, library, the department of scientific research and trade, the fire alarm system has e the necessary installation. The fire alarm system has important functions to the modern buildings. The fire alarm system controller is its core. We introduce the research of fire alarm controller and narrate its hardware and software. The fire alarm system controller is designed by the C8051F020 MCU, it has a high rate of capability and price, at the same time, it has many functions such as: handlers manage, alarm information inquire, detector manage, preparative alarm, the process of fire alarm, communication and so on. In the controller, the LCD display shows all kinds of fire alarm information.
The detector’s control circuits is designed by P87LPC762 MCU, it can detect and transmit the fire information. We design a coder for improving the system’s adaptability and reliability.
