针对现有煤矿馈电传感器对负荷侧为屏蔽线缆时不能准确检测馈电状态的问题,提出屏蔽式智能矿用馈电状态传感器研究方案。给出现有馈电传感器对屏蔽式线缆不能检测的原理,并结合目前矿方和实际安装需求,对馈电传感器总体设计、检测探头设计、信号处理电路和软件抗干扰信号处理算法进行了详细阐述。试验和使用结果表明,设计的屏蔽式智能矿用馈电状态传感器能够准确地判断出负荷侧为屏蔽线缆的馈电状态,准确地将负荷侧的馈电状态通过RS485接口接入现有的监控系统中,满足实际应用。
Aiming at the problem that the existing coal feeder sensor can not accurately detect the feeding status when the load side is a shielded cable, a research scheme of shielded smart feeder status sensor is proposed. The principle that the feeder sensor can not detect the shielded cable is given. The current sensor design, detection probe design, signal processing circuit and software anti-jamming signal processing algorithm are described in detail according to the current mine and the actual installation requirements Explain. The experimental results show that the design of shielded smart mine feeder state sensor can accurately determine the load side shielded cable feed state, the load side of the feed state accurately through the RS485 interface to access the existing Monitoring system to meet the practical application.
