Civil Air Defense Engineering Supporting And Maintenance Detection System Based On Wireless Communication

Civil air defense engineering is an important part of the national defense war ability,related to the rapid response ability facing the critical situation and natural disasters,regular maintenance of protective equipment is an important guarantee for the normal operation of protection engineering in critical time.This research under the background of informationization,using wireless network,detection technology,software technology to monitor and detect the artificial maintenance of protective equipment and automatic recording monitor.In this paper,a new method is proposed to detect the protection equipment and wireless communication,and the system is designed based on wireless communication,The major research and innovation achievements can be illustrated as follow:1.In view of the problem that the deformation of the protective door can only depend on the manual method,and the problems of low accuracy,high cost and poor real-time performance,creatively through mechanical design the touch screen and rheostat used in protective door in the detection of in horizontal and vertical offset distance,and through the wireless digital network transmits the data to the server,which can be queried offset information through the internet.2.In order to simplify the design of mechanical structure,the three-dimensional electronic compass used in the offset detection of the protective door,it can detect pitch angle,yaw angle and roll angle of the protective door,through the proposed coordinate transformation algorithm,the door status information is obtained,and the test results show that the design method can quickly and accurately monitor the opening state of the protective door and record the maintenance action of the protective equipment.3.Aiming at the limitation of the wired data transmission in underground environment,a transmission method based on wireless communication network is designed.According to the characteristics of underground space,planning transmission network,network can jump 5 level address,and using low frequency wireless data transmission system,improving the distance of data transmission and the ability to pass through the wall,to solve the problem of wireless data transmission in underground space,test results show that the design method of this paper can be used to carry out the remote data transmission in the underground environment.4.The civil air defense engineering monitoring system is constructed,including engineering classification,multi-level transmission address planning and data acquisition,to achieve a largenumber of civil air defense engineering maintenance automatic monitoring and related data services,the system has been tested.
