【技术实现步骤摘要】
本专利技术涉及监控系统,尤其是一种后端机装置。技术背景监控系统主要针对设备运行中的异常变化,特别是设备在连续的运行过程中 出现的各种突发性故障,及时发现设备运行过程中的故障现象并对故障进行分析 和诊断以确保设备始终处于良好的工作状态。涉及设备运行中各个参数的检测、 变化幅度的辨识、变化机理的诊断、故障影响的分析以及针对故障应该采取的处 理措施等。对大多数连续运行的设备而言,监控通常包括以下四个方面的内容1. 异常变化检测监视设备运行状态,检测设备运行规律或演化趋势是否 在某时间点或者该时间点之后发生了异常变化,并推断出发生变化的起始时间;2. 异常变化辨识如果设备发生了异常变化,识别变化类型和变化的幅度,以便对故障程度进行评估;3. 故障设备分离判断设备的异常变化是由哪个部件或设备运行过程的哪 个环节引起的,以查明故障形成的原因;4. 设备故障对策根据故障可能带来的不利影响,制定相应的处理对策, 以确保设备能正常运行或避免整个系统发生灾难性故障。无线干放监控是随着计算机控制技术以及网络通讯技术的发展而逐步发展起 来的监控领域的前沿技术,主要有远程监控与集中监控,集中监控即监控中心设 在某些干放周围,数据采集控制器与干放设备通过自制接口电路板实现通讯,数 据釆集控制器通过网络与监控主站相连,实现数据传输,对干放的运行状态进行 动态实时监控管理,可随时掌握干放的运行状态、统计运行数据;远程监控一般是通过电话网或无线网络进行数据传输的,干放监控系统采集端经过自制接口电 路板与电话网或无线网络连接,监控主站直接与电话网或无线网络相连。双方通 过各自的无线网络 ...
