摘要
传统火灾报警装置存在布线复杂、维护困难等问题,且经常出现漏报迟报现象,无法满足现代社会对火灾预警的深层次需要。因此,利用无线信号传输距离更长、无线唤醒、绕射障碍物能力更强的XL1101-D01无线射频芯片为媒介组建无线传感网络,通过RS-485、RS-232通信方式与上位机管理平台进行数据交换,构筑具有良好准确性和重复性的火灾报警监测系统,为早期处置提供积极支持。
Traditional fire alarm devices have problems such as complicated wiring and difficult maintenance,and often miss and report late,which cannot meet the deep-seated needs of modern society for fire early warning.Therefore,the XL1101-D01 radio frequency chip with a longer wireless signal transmission distance,wireless wake-up and stronger ability to diffract obstacles is used as the medium to form a wireless sensor network.Through RS-485 and RS-232 communication methods and the host computer management platform,data is exchanged.And the fire alarm monitoring system with good accuracy and repeatability is constructed to provide active support for early disposal.
