室内管控系统的设计与实现

AbstractSTC12C5A60S2 single chip microcomputer is used as the corecontroller of the indoor disaster control system designed in this system.Each function of the system is closely related to the single chipmicrocomputer.The clock module DS1302 provides the display timeparameter for the liquid crystal display.The gas concentration sensormodule mq-2 monitors the concentration value of the disaster gas in theindoor air in real time,and then sends the detected data through the serialport communication To single chip microcomputer;two wireless serialport modules hc-12 do data transmission on upper computer and lowercomputer,transmit alarm or stop alarm message;motor driving module19110 drives water pump to control possible disasters in real time whenthe concentration of disaster gas is too high;LCD1602 displays timeparameter,current concentration value and concentration peak value setby users to control the system It is realized and used in a unified way.Sothat when the indoor emergency disaster,the people inside the buildingcan be timely alarmed,and the root of the disaster can be timelycontrolled and alarmed.At the source,timely and effective monitoringand detection shall be carried out for the possible indoor disasters toensure the safety of people's life and property and reduce social andeconomic losses.Key words:STC12C5A60S2 single chip microcomputer;motordrive;wireless serial port;sensor;
