可视化电气火灾预警系统的设计与实现

Design and Implementation of Visual Electrical Fire Early-Warning System

设计一种基于CORTEX-M3平台的电气火灾预警监控系统,通过判断剩余电流和环境温度,实现对电气火灾有效的预防.系统采用总线型结构,分为中心监控平台和前端报警探测机两个部分.中心监控平台通过RS-485网络可同时连接127台探测机,监管1 016个监控区的火灾数据;采用QVGA彩色液晶触摸屏,嵌入中文菜单,以较少的资源实现友好的人机交互界面.测试结果表明:该系统各项指标均符合国家标准,而且稳定性好、性价比高.

Designed a fire alarm monitoring system based on the Cortex-M3. By detecting the residual current and the environment temperature, the system prevented electrical fire effectively. The system used bus structure and divided into two parts, the central monitoring platform and front-end alarm detection machine. By using RS-485 network, center mo- nitoring platform can connect 127 detection machine and monitor the 1 016 area fire data; the system used QVGA color LCD touch screen and embeded a Chinese menu. The system achieved a friendly interface with few resources. Test results show that： the system＇s indicators are in line with national standards and have good stability and high performance price ratio.
