火灾报警系统的后台通信设计与实现

火灾报警系统的后台通信设计与实现
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。本文的主要研究内容如下：
1. 对串口通信的基本原理和串口标准进行了详细的阐述，对报警主机进行了协议分析的技术原理及分析过程的论述。通过对报警主机通信协议的研究，提出了进行协议分析的技术方案，通过监听、透明转发等手段获取数据包，经过分析、比较、验证，最终得出了各台报警主机完整的通信协议，保证了消防集成项目的顺利完成。
2.针对“串口通信协议分析”、“网络通信协议分析”，编制相应的工具软件，大大方便了协议分析的工作。
3.完成了整个系统的实现。该系统的实现和应用，不仅了提高消防工作的管理水平和效率，降低人员和资源的成本，也有利于城市火灾自动报警监控管理中心的通讯。方便今后将分散的在各个单位的消防系统的信息进行全局的实时的监控和管理。
本文设计的火灾报警系统能有效地防止和减少火灾危害，对保护人身安全和财产安全具有现实意义。

ABSTRACT
The fire has become fat and often destructive, as well as the most influential one of the disaster. With the economy and the rapid development of urban construction, urban high-level, underground construction, as well as large-scale integrated construction increased fire danger has also increased significantly, the number of fires caused by its loss was on the rise year by year. In the industrial and civil buildings, hotels, hotels, libraries, scientific research and commercial departments, fire alarm systems have become an essential device. The fire alarm system for modern architecture plays a vital role in security. The main contents of the study are as follows:
1. Serial communication on the basic principles of the standard serial port and a detailed explanation of the police carried out a host of technical analysis of the agreement and the principles of discourse analysis of the process. The alarm host communication protocol, put forward an agreement to carry out the analysis of the technical program, through listening, transparent, and other means of access to transmit packets, analysis, comparison, verification in order to work out a warning to Taiwan host the integrity of the communication protocol to ensure that Fire the integration of the successful completion of the project.
2. The "serial communication protocol analysis" and "Protocol communication network" and corresponding software tools that greatly facilitate the analysis of the agreement.
3. To complete the entire system. The system and applications, not only is to improve fire prevention and management efficiency and reduce the cost of personnel and resources, but also conducive to the city to monitor the management of automatic fire alarm communications center. Convenient in the future will be scattered at various units of the Fire Information System for the global real-time monitoring and management.
In this paper, the design of fire alarm systems are effective in preventing and reducing fire hazards, to protect the personal safety and property of practical significance.

KEY WORDS：Fire alarm, serial communications, interface standards, communication protocols
