Design Of Controller Array For Fuze Dynamic Induction Setting Verification System

In the modern intelligent weapon system,in addition to the basic functions of detonation,the fuze needs to combine the set target information and environmental information to achieve the detection of the damage target and the precise control of the explosion point.At present,the fuze dynamic induction setting is a relatively advanced setting mode for small-caliber guns.The fuze setting system is connected to a plurality of devices such as a fire control platform,a meteorological device for data setting and so on.However,in the high-speed operation environment of the existing setting system,the communication link is prone to waveform distortion,resulting in the loss of the set data,etc.,thereby reducing the killing performance of the projectile.In order to improve the reliability of the fuze setting and raise the success rate of system development,it is urgent to develop a fuze dynamic induction setting verification system for setting the reliability test.Aiming at this situation,this paper mainly designs a controller array sub-system of fuze dynamic induction setting verification system based on multi-processor and multi-communication interface.The sub-system combines the software monitoring platform and the sensing information communication link to realize the experimental verification of the reliability of the fuze dynamic induction setting information,which accurately obtain the various technical states of the setting system.Among them,the design of the fuze dynamic test setting verification system controller array sub-system implements seven kinds of communication interfaces such as RS232,RS422,IEEE 1394,TCP/IP,CAN,USB,?C based on four kinds of processors such as MCU,ARM,DSP,FPGA.After selecting the main component model according to the project requirements,the relevant circuits are designed through ADS software,building the relevant hardware platform.The exploitation condition and programming mode of each processor is studied,achieving the software development of the system based on C and Verilog HDL language.At the same time,a set of auxiliary control sub-system is designed,which realizes the automatic selection of the working processor and the required communication mode through the relevant instructions.The development of the communication protocol between the auxiliary control sub-system and the software monitoring platform is completed.Through the test of sending and receiving data multiple times on the communication interface,the test results show that the implemented functions basically satisfy the expected design goals of the system.The controller array sub-system designed in this paper has a variety of working modes,which can be applied to most weapon systems for fuze setting reliability verification experiments.The use of this system can greatly reduce the development cycle of the fuze setting and the related funding investment.It is of great significance to promote the generalization and systemization of the fuze dynamic induction setting verification platform.
