摘要
蓄电池在备用电源中是重要的储能设备,直接关系到整个备用电源系统的可靠运行,因此及时可靠地对蓄电池组进行监测具有十分重要的意义.为此提出了一种蓄电池电压和温度的分布式监测系统,给出系统总体设计方案,在蓄电池组中为每个单体电池配置一个监测单元,分析了单元的结构和功能,以MC9S08QG8单片机为核心实现了单体监测单元,并且通过485总线可与上位机实现通讯.通过实验,验证了所提出的蓄电池分布式监测系统的可行性.
Accumulator is the important energy storage equipment in the backup power supply, and its status affects the reliability of power supply. Therefore it is very important to monitor batteries in time. This paper proposes a kind of distributed monitoring system for monitoring cell voltage and temperature, and the overall design scheme of the system which allocates one monitor unit for every cell in the accumulators, and then analyzes the structure and function of the unit which adopts the core MC9S08QG8 microcontroller as the single monitor unit to achieve communication with PC through 485. The feasibility of the distributed monitoring system of accumulator is verified through experiment.
