The Application And Research Of FPGA In Induction System

The development of science and technology in today's high-speed society,the speed of development is very rapid.The development of national defense science and technology is of vital importance to a country,and national defense weapons and equipment have been continuously upgraded along with the progress of science and technology.The fuze technology greatly improves the precision of the projectile,and makes the projectile's combat mode become diversified,making it easier to adapt to the changeable battlefield.The application background of this paper is large-caliber artillery,and the design of induction loading system based on FPGA chip.The system is divided into two parts: the loader and the receiver.The device is connected to the upper fire control computer through the USB serial port module.Data from the PC to the determined system of setting,after setting a series of coding,modulation and power amplifier is loaded into the primary coil,through the secondary coil of electromagnetic induction in the form of transmission to the receiver,then the receiver to restore the data after demodulation and decoding and calibration,and verified the data storage.In this paper,the overall design scheme of the induction loader system is firstly constructed.The main functions are realized by FPGA chip.FPGA can be used to integrate part of the hardware circuit of the induction loader and improve the data transmission rate.The code inside the chip is designed from top to bottom,and the architecture and functional modules are designed layer by layer according to the functional requirements.The FPGA chip of EP4CE10F17C8 N from Altera was used as the control chip in the loader and receiver.In this article,the function verification of induction setting system mainly divided into three methods,through modelism to timing simulation code SignalTopⅡ logic analyzer for board level analysis and debugging,finally an experimental platform for data transmissiontest results.
