摘要:针对炼铁炼钢生产中大量行车工作在高温环境,电缆容易老化而又无法获取其剩余寿命的问题,选用半导体测温元件AD590在线监测电缆运行温度,采用直接测定和神经网络预测2种方法计算电缆剩余使用寿命,优化电缆更换周期,实施部分电缆更换.并将预测数据作为电缆采购决策的依据,可降低库存资金和库存成本.

关键词: 行车, 电缆寿命, 温度监测, 神经网络

Abstract: In smelting process,large amount of cables of crane working in hot environment are likely to reduce its useful-life that can’t be known.Inallusion to the question,a temperature inspector system with a semi-conductor element AD590 was designed for monitoring the actual operating environment and status of those electric cables.Directly measure way and NN forecast were used to calculate the cables useful-life.And the period of cable replacement could be more optimized.Also it is possible to replace the cables by stages and in batches.By this prediction data to stock cables,the repertory capital and cost will be lowered.

Key words: crane, cable useful-life, temperature monitoring, NN
