Design Of Human Defense Communication System Based On Frequency Hopping

At any time,an important component of the urban air defense system has been an air defense alert.For a city,the air defense alarm system is always the most important combat readiness facility.At the time of the war,air defense warning system can be used for civil air defense,and it is an important means for governments at all levels to direct the evacuation of people and protect people's life and safety.In peacetime,the alarm system is usually used to carry out emergency and disaster forecast for accidents and disasters.In the context of the rapid development of science and technology,and the warning of air defense warning closely related to national security interests and people's life and property security,it is necessary to be more efficient and reliable.Therefore,the research of this topic has the extremely important status and significance.This paper expounds the relevant technical foundation theory in the alarm system and designs the alarm system based on actual demand and theoretical research.Firstly,the paper analyzes the background and significance of the research,expatiates the basic theory of frequency hopping technology adopted by the wireless communication in the alarm.According to the different hardware parts,the corresponding personalized requirements in the actual application include: main control center station,alarm control terminal and data transmission relay station respectively.This paper mainly realizes the design of the power supply circuit of the front-end digital transmission module frequency-hopping signal transmitting and receiving,perfecting interactive design based on the demand of different parts.In the system software design,the overall architecture design of the system software was first made.In view of the safety and convenience of data protection and data maintenance,the key is to realize reasonable software database design,to add GIS map in software design,and to monitor terminal status in real time.Finally,the system test case design was completed,the test case of the design was tested and the test results were summarized.This paper study the content of the system is of great significance for city air defense system,and this topic design of civil air defense alarm control system,not only can enhance the capacity of warning issued by the management,improve the accuracy of the issuance of civil air defense alarm,at the same time because of its characteristics of the automatic and intelligent greatly reduce the pressure of the use of related management part maintenance.
