The Design Of Intelligent Control System For Civil Air Defense Project

This paper designs an intelligent control system for civil air defense project against the problem of incomplete control function and decentralized structure of the control system.The system adopts ARM chip processing high-speed data acquisition,signal circuit design of signal acquisition boards function,The communication between the lower computer and the upper computer is realized by using optical fiber Ethernet,the man-machine interaction software of client/server structure is designed.Real-time monitoring of the environment and equipment status of the civil air defense project,when the system is abnormal,it will immediately alarm,historical data and alarm records are stored to the central server.The system is responsible for the safety monitoring and management of civil air defense project.The research contents of this paper mainly include the following aspects:(1)According to the characteristics of the civil air defense project,the functional requirements of the intelligent control system for the project are analyzed,and the overall design and system development process of the intelligent control system is formulated.Carry out the overall design of the software and hardware scheme and Complete the system hardware network.(2)The design of the system hardware circuit,including signal acquisition boards,sensor signal conditioning circuit,alarm circuit,control circuit,electronic fan closed air valve control circuit,sewage pump control circuit,power supply circuit.The environment and equipment status data are sent to the signal acquisition board,and the device control circuit includes two working modes: field control and remote control.(3)The design of system control terminal,remote control terminal receives the human engineering environment and equipment condition data,and store to the central server,the environment status in abnormal data and equipment state control terminal trigger the alarm.The control terminal provides automatic generating report and trend chart function.Ethernet communication programs and server programs are designed for data transmission and storage.(4)Make all kinds of sensors installed in the corresponding points,to complete field debugging for the intelligent control system.The sensors are accuracy and control terminal displays normal by observing,it proves the validity and reliability of the system.
