提出一种基于支持向量机实现瓦斯抽放监控系统故障诊断的方法。首先总结归纳系统故障类别,然后,选择多项式核函数进行系统参数样本数据训练,建立分类器。通过白皎矿实时监测数据验证,说明此方法故障诊断定位准确,能够保障煤矿瓦斯抽放系统安全维护和运行。 A method of fault diagnosis of gas drainage monitoring system based on support vector machine is proposed. First of all, summarizes the system fault categories, and then selects the polynomial kernel function to train the system parameter sample data to establish the classifier. Through the real-time monitoring data of Baijiao Mine, it shows that this method is accurate in fault diagnosis and positioning and can ensure the safe maintenance and operation of coal mine gas drainage system.
