阀控式密封铅酸蓄电池在线巡检系统的研究与设计
摘要
阀控式密封铅酸蓄电池广泛应用于电力操作电源、通信电源等系统中,其安全可靠的
运行极为重要。但由于蓄电池结构的特殊性、使用数量多、情况各异、人工维护蓄电池组
的工作量大,往往容易损坏而不易察觉,从而造成资源配置的浪费。因此,随着阀控式密
封铅酸蓄电池的大量应用,其在线的实时监测、早期故障诊断和维护已经十分迫切。市场
上各类型电池监测系统也在广泛使用,但不同的测试方法对蓄电池的性能好坏反映也不尽
相同。多年的研究和运用表明,内阻检测是目前最为可靠的测试方式之一。本文对阀控式
密封铅酸蓄电池的特性和检测方法等进行了深入的分析与研究,主要内容包括:
(1)概述了国内外蓄电池在线巡检系统的研究现状与发展趋势;
(2)研究了阀控式密封铅酸蓄电池的工作原理,分析了蓄电池的性能与其内阻之间
的关系;
(3)研究了阀控式密封铅酸蓄电池内阻在线检测方法,详细分析了利用锁相放大技
术对蓄电池内阻的测量原理;
(4)完成了系统的硬件设计,包括前端内阻测量电路、单片机控制和显示系统;
(5)完成了系统的软件设计,包括上位机和下位机软件;
(6)成功制作样机,经现场测试,应用效果良好。

STUDY OF THE VALVE-REGULATED LEAD-ACID
BATTERY ON-LINE MONITORING SYSTEM
ABSTRACT
Valve Regulated Lead Acid Battery is widely applied to the systems of electrical supply
munication power supply. It is most important to work safely and reliably. But the
structure of battery is particular and the number of battery is very large. It is easily destroyed
while not be noticed, so it is urgent for the people to make an detecting equipment that can figure
out the battery quality online in case of waste and accident. All kinds of the detecting
equipments is widely used in the market. While the different testing methods to the battery are
good or bad. It is pletely identical, reflecting the different results. Years of study and
use that internal resistance detection is the most reliable . This article has deeply analyzed the
features and the testing ways of Valve Regulated Lead Acid Battery, The main contents of studies
includes:
(1)The introduction of the current situation and developing trend for Valve Regulated Lead
Acid Battery;
(2)The research of the principle for Valve Regulated Lead Acid Battery and the study of
technique parameter and relation for internal resistance;
(3)The detailed analysis of on-line detectio
