Research On Embedded Intelligent Fire Control And Integrated Information Monitoring System Based On Cotex-A9

With the construction of modern urbanization,the building structure is more and more complex,and the electrical power is more and more large,resulting in a higher and higher probability of fire,which poses a great threat to the safety of people and property.In today’s society,there are many problems in the fire protection system,such as the alarm is not timely,false alarm,missed report,after the fire can not timely deal with the fire.Therefore,it is necessary to study an intelligent fire control system with quick response,high stability and good real-time performance.The rapid development of sensor technology,communication technology and embedded technology provides technical support for the embedded intelligent fire protection system proposed in this paper.The system studied in this paper places fire detection sensor nodes in multiple regions and locations,and USES CAN bus communication technology to form a network of these nodes for fire detection.The system adopts the distributed control mode,that is,an embedded centralized controller and multiple micro controllers,which improves the stability of the system control.The centralized controller sends the data of the lower computer to the upper computer through the network for display in the LabVIEW interface to realize the intelligent display of the fire information.Firstly,this paper designs an intelligent fire detection system,which includes a fire detection system and a CAN bus communication system.The fire detection system sends the detection data to the database of the server in real time and stores it for the convenience of personnel to consult.The detection node conducts data transmission through the communication mode of CAN bus,which has the advantages of simple structure,strong anti-electric interference ability and strong real-time performance,etc.,making the data transmission of the system more stable.Secondly,this paper designed an intelligent fire linkage system,including sound-light alarm,fire shutter door,and emergency lighting.These linkage devicesare directly controlled by S3C4412 centralized controller to realize alarm processing automation and improve the reliability and real-time performance of the system.Finally,this paper designs an intelligent fire integrated information monitoring system,which USES LabVIEW to design the login interface,fire detection interface,fire linkage interface and fire linkage equipment power monitoring interface,and designs the database through SQL Server.The system has completed the functions of fire location,fire alarm,fire history inquiry and user friendly interface.The Embedded intelligent fire control and comprehensive information monitoring system based on cotex-A9 has the characteristics of high reliability,rapid reflection and good real-time performance,but it still has some shortcomings.
