The Fire Control Computer Multifunction Board The Design And Realization

The Fire Power Control computer is the most important core constituent of the Fire Power Control system. The Fire Power Control computer solves problem which is the artillery projects the trajectory resolving and the movement goal lead estimation problem emphatically. when Ground warfare platform is firing, the Fire Power Control system first constitution line of sight through optics telescopic sights aiming and tracking goal.After the learning object distance and the velocity of movement, the Fire Power Control computer calculates the firing data (i.e. artillery height to angle of fire which approaches with level), then controls the artillery (spool thread) to fire.The multifunction circuit board is one of core parts in Fire Power Control computer.The Fire Power Control computer usually is composed of the CPU motherboard, the CAN communication board, the serial port communication board, the power source transforms module, the matrix keyboard transfers board and the digital I/O board.The CAN communication board, the serial port communication board, the power source transform the module, the matrix keyboard transfer board and the digital I/O board are concentrate in the multifunction circuit board which has many kinds of functions.1. Study the development condition and the correlation theories knowledge of the CAN bus technology, the serial port communication technology and the CPLD technology. The it analyzes the reliability design about Fire Power Control computer multifunction circuit board.2. VHDL programming and the simulation.CPLD is the bridge of ISA bus.3. Finish the design CAN bus circuit, the serial port communication circuit, digital I/O circuit, the circuit of matrix keyboard transforms , the power-switching circuit 4. reliability computation of multifunction circuit board.the purpose of this article is to research multifunction circuit board, and propose a design proposal ,the realization method and the reliable computation of multifunction circuit board summarizing in the predecessor research results.
