室内管控系统的设计与实现.docVIP

内容摘要 此次系统设计的室内灾害管控系统采用STC12C5A60S2单片机作为核心控制器，系统的每项功能运行都与单片机息息相关；时钟模块DS1302为液晶显示器提供显示时间参数；气体浓度传感器模块MQ-2实时监测室内空气中灾害气体的浓度值，然后检测到的数据通过串口通讯发送至单片机中；由两个无线串口模块HC-12在上位机与下位机上做数据传输，传输报警或停止报警讯息；电机驱动模块L9110在灾害气体浓度过高时驱动水泵对可能发生的灾害进行实时管控；显示器LCD1602显示时间参数、当前浓度值以及用户所设定的浓度峰值等来对这套系统进行实现及使用。以至于当室内突发灾害时，可以对建筑物内部的人群进行及时的报警，并在灾害发生的根源处进行及时的控制以及报警。源头处对室内的可能发生的灾害进行及时有效的监检测，保障人们的生命和财产安全，减少社会经济损失。 关键词：STC12C5A60S2单片机； 电机驱动； 无线串口；传感器； Abstract STC12C5A60S2 single chip microcomputer is used as the core controller of the indoor disaster control system designed in this system. Each function of the system is closely related to the single chip microcomputer. The clock module DS1302 provides the display time parameter for the liquid crystal display. The gas concentration sensor module mq-2 monitors the concentration value of the disaster gas in the indoor air in real time, and then sends the detected data through the serial port communication To single chip microcomputer; two wireless serial port modules hc-12 do data transmission on upper computer and lower computer, transmit alarm or stop alarm message; motor driving module l9110 drives water pump to control possible disasters in real time when the concentration of disaster gas is too high; LCD1602 displays time parameter, current concentration value and concentration peak value set by users to control the system It is realized and used in a unified way. So that when the indoor emergency disaster, the people inside the building can be timely alarmed, and the root of the disaster can be timely controlled and alarmed. At the source, timely and effective monitoring and detection shall be carried out for the possible indoor disasters to ensure the safety of peoples life and property and reduce social and economic losses.
