摘要
现有煤矿安全监控系统不能实时在线检测备用蓄电池容量,造成交流断电后备用电池不能可靠运行。提出利用开路电压法检测备用蓄电池容量,通过LS-SVM对蓄电池放电数据进行训练,获取蓄电池端电压与容量的关系模型,在此基础上根据蓄电池端电压实现电池容量预测。通过实验表明,该方法能有效预测矿用隔爆电源备用蓄电池的剩余容量。
The backup battery can＇ t run reliably after the failure AC power, because the existing safety monitoring system used in mine can＇t detect the real-time spare battery capacity. The method of open circuit voltage was proposed to detect the capacity of backup battery, the relation model between battery voltage and battery capacity was achieved by using LS-SVM to train discharge data of battery, and then, the battery capacity could be predicted according to the battery voltage. The experiment results show that the method can predict backup battery capacity of mining flame-proof power effectively.
