A Firepower Distribution System Based on CAN Bus

The firepower distribution system can implement the function that the aiming sights control 4 guns.The firepower distribution system is an important constituent part of some weapon system,it consists of functional modules,such as aiming sight data collection board,main control board,display control board and relay board and so on.In order to improve real-time performance and anti-jamming performance of the system,taking TMS320F2812 MCU as core,the stand-alone CAN controller MCP2515 equipped with SPI interface was developed.Double CAN bus data network was used to combine each module with guns to realize some functions,such as double CAN bus data communication,data acquisition and data conversion and so on.By means of logic judgment of relay,the firepower distribution was performed.The results proved that the operation of system is stable and reliable,its data conversion is complete,and it can meet the requirements of actual application.
