一种基于CAN总线的火力分配系统

A Firepower Distribution System Based on CAN Bus

火力分配系统可实现瞄具带4门火炮的功能,是某武器系统的重要组成部分,由瞄具数采板、主控电路板、显控电路和继电器板等功能模块组成。为使系统具有良好的实时性和抗干扰能力,以TMS320F2812单片机为核心,扩展具有SPI接口的独立CAN控制器,采用双CAN总线网络将各模块及火炮连接起来,实现双CAN总线数据通信、数据采集和数据转换等功能,通过继电器的逻辑判断,完成火力分配。实践证明,该系统运行稳定,数据传输完整,满足实际应用的要求。

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.
