基于CAN总线的指挥车电源管理系统设计

指挥车上的用电设备多,对供电品质要求高,传统的电源管理系统已无法满足系统的要求。设计了一种以数字信号处理器(DSP)和单片机为控制核心,采用CAN总线进行通讯的电源管理系统。系统采用模块化的设计思想,实现了系统关键部件的可换性,拓展了电源系统的工作条件;采用各种可靠性设计方法有效地抑制电网波动,改善电磁环境,提高系统供电品质和可靠性,为指挥车辆电源管理系统设计提供了一种可行的方案。

Design of Power Management System for Command Vehicle Based on CAN Bus

There are many electric equipment in the command vehicle,which require good power quality.The traditional power distribution mode can ’t meet the need of the system.A power management system was designed in this paper,Which used the Digital Signal Processing and Single Chip as the control core,used CAN bus as communication tool.The key parts in the system can be interchanged due to the modularization design,which can extend the working condition of power system.Many strategies for improving the reliability of system was prompted to restrain the fluctuation of power resource and to improve the power quality and EMI condition.This paper provide a feasible project for command vehicle power management.
