养老院周边灾害自动报警系统设计

Design of Automatic Alarm System for Disasters around Nursing Homes

养老院通常建在安静的郊区,常常是依山旁水的区域,而山体滑坡、泥石流或洪涝灾害在此类地区常常发生。为了帮助人们在灾害发生时及时撤离危险区域,本文设计了一种灾害自动报警系统。本系统包括主机与从机。主机模块主要是显示和报警,放置在人们易于观察到的地方,从机包括山体滑坡模块和河流水位监测模块。各个模块与主机之间采用LoRa无线通讯技术,自然灾害发生后通过无线通讯技术向主机发送报警信息。主机接收到报警信息后,首先进行声光报警,然后分析报警信息的来源并在屏幕上显示自然灾害信息。经调试后,系统运行良好,在养老院建设中具有极大的推广价值。

Nursing homes are usually built in quiet suburbs,often in areas surrounded by mountains and water,and landslides,mudslides or floods often occur in such areas.In order to help people evacuate from dangerous areas in time when disasters occur,this paper designs an automatic disaster alarm system.This system includes master and slave.The master module is mainly for display and alarm,placed in a place where people can easily observe,and the slave includes a landslide module and a river water level monitoring module.LoRa wireless communication technology is used between each module and the host,and after a natural disaster occurs,an alarm message is sent to the host through wireless communication technology.After the host receives the alarm information,it first performs an audible and visual alarm,then analyzes the source of the alarm information and displays the natural disaster information on the screen.After debugging,the system runs well and has great promotion value in the construction of nursing homes.
