Reconfigurable Integrative Telemetry And Telecontrol System Base On OpenVPX

With the development of missile technology and complex changes of modern warfare confrontation situation,the development of missile weapon has been confronted with the progressively increasing threat and the electromagnetic environment where it is applied has been becoming more complex as the technology develops.The missile weapon system has equipped with more and more electronic equipment in order to improve the defense penetration rate and survival rate of itself,including the electronic reconnaissance,ra dar warning and electronic interference,etc.on the battlefield.However,it is followed by that the wide range of electronic equipment is bound to bring more energy consumption on the missile,take up more inner space of it at the same time and increase the non-effective mass and volume of weapon and sectional area of the missile body that reflected to radar.The serious mutual interference has reduced the effective combat effectiveness of missile equipment.The restrictions on the inner narrow space design of weapon and missile make it harder to load more effective load,thus limiting the combat capability.However,the traditional missile electronic system adopts a large number of independent stand-alone equipment and arranges them in the missile instrument compartment loosely.This simple distributed RF equipment has disadvantages of sophisticated design,high cost,poor use reliability,bigger weight volume,large electronic power consumption,poor expandability on the electromagnetic compatibility,whi ch have seriously limited the expansion of electronic warfare function of missile and improvement of defense penetration ability and can't meet the demands of the information-based and systematic combat of missile of next generation.In conclusion,it is in urgent need to study the integrated comprehensive multi-function observation and control technology,including the hardware synthesis,software synthesis,information fusion and radio frequency synthesis,to realize the integration,light weight,small size and low power consumption and have conditions for expanding more functions;study the open type and extensible electronic system architecture to expand the new functions flexiblely and realize the modern electronic "growth" measurement and control eq uipment with "upgrade" capability.This topic mainly studies the completion of acquisition of the state parameter,environmental data and flight ballistic data of systems in the flight under the Open VPX architecture to provide the basis for performance ev aluation or fault analysis and design improvement;to provide telemetering and external ballistics measurement information for the security control implementation of ground wireless security control system and to implement the security control by receiving the instructions that issued by the ground wireless security control system.In the comprehensive testing of system,firstly,it includes separate module testing and whole machine system testing.In the whole machine testing at last,it has conducted more electromagnetic compatibility testing related to hardware and robust functional testing on software to verify the feasibility,reconfigurability and stability of measurement and control system designed by this topic as a whole and that all indicators and performances meet the requirements of anticipatory design.
