Hardware Design And Implementation Of An Artillery Fault Detection System

In recent years, with the popularization of air defense missile, missile becomes dominant weapon in the air instead of antiaircraft artillery, but antiaircraft artillery still own many advantages that missile doesn't have. With the development of antiaircraft artillery in the automation and intelligent direction, technology of antiaircraft artillery become more and more complex and the internal structure become more and more exact. For this reason, the test of antiaircraft artillery system extends the higher requirements. This article focuses on the design and debugging of the fault detection system hardware of an artillery weapon.The fault detection system hardware, relying on a particular type of industrial computer, is based on the computer's PCI bus and completes collection and transmission of fault information of a anti-aircraft system. Hardware includes PCI interface through the PCI9052 chip, one RS-232, two RS-485 and two CAN communication interfaces and a GPS module. In addition, the programmable logic device EP3C10E144C8N is programmed by schematic and Verilog HDL language in order to achieve sequential synthesis, address allocation, second frequency, interrupt control, and convert the time date of GPS module to IRIG B code formats. In addition, through setting the PCI9052 chip external memory EEPROM, board can achieve Plug and Play (PnP) in the Windows XP operating system.The board has passed the test of data acquisition and communication. In the test, transmission speed of the board is fast without delay. Board is stable, with little error rate of transmission, achieving plug and play function. In addition, board is able to work long hours under harsh conditions, achieving design requirements of the fault detection system of the artillery.
