The fuze setting is critical in the fuze design of each weapon system.And the fuze mouthwash dynamic induction setting is a set mode with outstanding advantages and wide application.The verification system of dynamic induction setting is a reliability test system for this type of setting.Due to the variety of communication interfaces and processor models used in each weapon mounting platform,the difficulty of setting up the verification system increases,which is not conducive to the modularization and systemization of this type of setting system.To solve this problem,it is urgent to design a universal verification system that can serve for multiple weapon platforms.As the measurement and control center of the whole verification system,the verification system simulation platform of dynamic induction setting designed in this paper has practical engineering application value for improving the flexibility and generalization of the dynamic induction setting verification system.This paper mainly studies the design and implementation of the simulation platform for dynamic induction setting verification system.This simulation platform realizes the real-time monitoring of the verification system,which can processes and analyze the test data.In the first,the paper introduces the background of the research and the current research status in civil and abroad,and formulates the averrall design scheme of simulation platform according to the needs of the project.The communication design part of the system is completed secondly,in which the parameter configuration based on serial communication and the data acquisition based on USB communication are realized.Simultaneously,the communication protocol with the lower computer is established.According to the software function requirements,the paper realizes the interface design of the simulation platform under the LabVIEW 2017(Laboratory Virtual Instrument Engineering Workbench 2017)development platform.The software platform adopts a software design mode combining multi-thread technology with event structure,which solves all operations,data acquisition and timing problems of process in the response software of the front panel user.The NI-VISA function combined with the structure function realizes the waveforms data acquisition of 8 monitoring point.Data analysis and real-time display of waveforms of the monitoring point arc achieved using LabVIEW software’s own functions and various controls.Taking advantage of the signal processing functions in the LabVIEW function palette,the demodulation decoding solutions for three modulation of 2ASK,2FSK,2DPSK are realized.And then,this paper completes the simulation and test to restore the collected high-frequency signals.Then,in order to manager the configuration data,test information,save data and uery the historical data,the NI Database Connectivity toolkit and the Microsoft Access database are used.Finally,the laboratory test environment is built for purpose of the system function test and the software and hardware joint debugging,Therefore all the functional modules of the simulation platform are verified.The test results show that the number of acquisition channels of the simulation platform is 8,and the relative error between the collected data values and the theoretical values is below than 0.5%.Under the test and simulation environment,the decoding accuracy rate of demodulation and decoding module achieves the requirements of system design indicator.In the test environment built by the laboratory,the decoding accuracy of the three demodulation methods is all greater than 99%,which realizes the preservation,reading,analysis and query of the test information.The simulation platform has perfect functions and reliable data collection,which realizes the design goals of the real-time monitoring and verification system.
