摘 要:煤矿井下对电机运行状态检测有很高要求,现有用于电机检测的主要是有线在线检测设备,面对海量数据处理负担重,对数据传输的要求很高;此外,煤矿井下环境恶劣,铺设有线通信线路难度大。为此,文章对无线振动边缘处理装置进行了设计,采用双核主控芯片LPC55S69,可实现小波变换和无线通信的协同运行,数据在该装置中得以处理筛选后(降低了对数据传输的要求),以无线方式经网关上传至上位机进行监测报警,实现了电机运行健康状态检测。

Abstract: There are high requirements for motor running state detection in underground coal mines. The existing equipment for motor detection is mainly wired online detection equipment. Facing the heavy burden of massive data processing, it has high requirements for data transmission; in addition, the underground coal mine environment is bad, and it is difficult to lay wired communication lines. Therefore, the wireless vibration edge processing device is designed in this paper. The dual core main control chip LPC55S69 is used to realize the cooperative operation of wavelet transform and wireless communication. After the data is processed and screened in the device (reducing the requirements for data transmission), it is uploaded to the upper computer wirelessly pass through the gateway for monitoring and alarm, so as to realize the detection of motor operation health status.

煤矿井下电机运行状态是否健康,直接关系到井下大型机械的安全性和可靠性。煤矿井下环境恶劣,电机长期在复杂的环境下工作,不断受到煤渣的影响抑或磨损轴承,会造成电机转子偏心严重使定子和转子相互摩擦,使电机产生剧烈的振动并发出不均匀的摩擦声,并且使电机机壳温度迅速升高,进而造成传动装置工作面坍塌等严重问题。通过观察电机的振动烈度来确定电机的运行状态,现有的诊断方法通常是使用有线在线监测装置或者是采用人工定期检测的方式,有大量的数据不断地上传到上位机进行处理,但是煤矿井下电路复杂、环境恶劣,铺设有线通信线路成本高、难度大,同时数据全部在上位机进行分析处理,使上位机诊断处理数据有很大的负担,存在严重的资源浪费和诊断不及时的问题。……
