【摘要】 为提高自动气象站蓄电池的维护效率,本文将预测性维护引入气象保障领域,通过对蓄电池预测性维护的技术要点、测试方案及流程等的介绍,选取3种不同劣化程度的蓄电池依次进行离线状态测试、浮充状态测试以及放电测试,通过数据对比分析初步给出了蓄电池预测性维护监测系统的综合评定。结果表明,在浮充状态下,监测系统电压和内阻的测试精度良好,能够很好地测试出蓄电池在不同健康状况下的电压与内阻值,即对报废电池、具有一定劣化程度电池和新电池的测试数据存在显著差别,在自动气象站蓄电池预测性维护中可利用浮充状态下测得的内阻数据对蓄电池劣化程度进行有效判别。更多还原

【Abstract】 In order to improve the efficiency of battery maintenance at automatic weather stations,we adopted predictive maintenance ideas into meteorological support areas. First,we carried out an introduction to the strategic points,test programs and processes of battery predictive maintenance. Then,we assessed preliminary the battery monitoring system by analyzing relative data which was obtained by a series of testing including offline testing,floating testing and discharging evaluation. The results showed that test precision of the voltage and internal resistance obtained by the monitoring system in the state of floating charge was favorable and could present significant differences for batteries of varying health levels,so we could ascertain the deterioration extent of battery by the internal resistance effectively on predictive maintenance of battery at automatic weather stations.更多还原
