摘　　要：介绍了一种利用嵌入式技术设计的海洋仪器电池管理系统。电池管理终端以ARM9处理器为核心,包括电池参数采集、WiFi通信、串口通信等模块。各电池组巡检节点之间通过RS485总线进行通信,主节点与上位机之间可通过无线与有线多种方式进行通信。电池管理终端移植Linux操作系统,实现了电池管理监控多项任务的有效调度与交互。电池管理系统可实现对各个电池电流、电压和温度的实时采集与SOC的计算。经过电池标定实验证明,系统数据测量可靠易行。A marine instrumentation battery management system is designed by utilizing embedded technology. The BMS terminal uses ARM9 as processor core, including battery parameter acquisition, WiFi communications and serial communications modules. Each bat tery pack between the nodes communicates via RS485 bus, and the master node communicates with the host computer by variety of wire less and wired ways. BMS terminal importes Linux operating system, and it achieves an effective scheduling and interaction multiple tasks. BMS can acquire real-time data of each battery current, voltage and temperature and calculate SOC. Battery calibration tests proves that it＇s a reliable and easy data measurement system.
