Research And Application Of Electric Fire Monitor System Based On The Technique Of Embedded Internet

Since the year when《Code for fre protection design of highrise buildings》GB50045-95(2005)made the electric fire protection as a single task, more than two years have pasted. Go with people's ideology and knowledge become maturer and maturer and products from some manufactories develop faster and faster, the application of electric fire system just at the period which from the babyish and fickle phrase to the becoming mature and developing steadily phrase. Through the developing period, the appearance of problem is inevitable. At the present time, in the industry of electric fire system, most system are simple RS-485 system, the system's localization and loneliness is becoming clarity day by day.This thesis takes the the electric fire monitor system which is installed in a company's project in Beijing for research, narrates the principle of electric fire monitor system and the implement of long-distance monitor system which is based on embedded internet, just for the problems in the electric fire system at present, at the premise of making no change for substrate frame, it takes the technique of embedded internet for development of monitor terminal in existing system.The thesis mostly takes the electric fire detector which is producted by the company and embedded host computer for designing hardware environment, takes embedded Linux operating system for designing software environment for monitor system, make Bootloader,the kernel Linux-2.6.14.1,the root file system cramfs step by step, and repot them into hardware whose core is 32 bits embedded micro processor.Following the require of building site of electric fire monitor system and correlated standard of government , in the embedded host computer, I mostly have worked on several aspects below: analysed the existing status of embedded GUI, introduced Qt's principle of signal and slot, chose the Qt/Embedded technique for development of GUI; for the need of data storage, embedded the embedded database SQLite; worked over the principle and correlated technique of embedded Web server, after comparing one server with others, chose the Boa for develop the system, in order to solve the problem of loneliness, and made the true meaning long-distance monitor come true.At last , the thesis analysed the detail condition of project, and compared the solved scheme with the existing system, summarized the scheme's anticipating effect and real meaning. The analysis indicated that the scheme had very good feasibility, and had great marketable foreground.
