Graphic Monitor And Control Of Automaticfire Alarm System

The paper presents a software of graphic monitor and control of automatic Fire Alarm System(FAS) which is developed by Microsoft Foundation Classes(MFC) of Microsoft Visual C++6.0. The paper firstly analyzes the actualities of graphic monitor and control of FAS at present. Then, the framework and the functions of every module of the software are introduced. As emphasis, the register module and graphic display module are expounded detailedly on the implementation of function and construct of code by MFC of Microsoft Visual C++6.0.The software consists of the graphic display module, register module, communication module, linkage module, historical data recording module and printing module. When the software system is on working, the user interface is operated through main thread, and the background thread is used to communicate with the lower controller.Since the software of graphic monitor and control of FAS adopts graphic file in vector format, it makes the building plan view for the fire alarm can be smoothly zoomed and scaled without jaggy distortions. And based on the fire alarm building plan view, The user can precisely and quickly locate the fire alarming spot where the fire...
