滤池就地控制单元包括:单格滤池控制、C网络管理(CCLINK网络)、R网络管理(RS485网络)、人机界面、实时数据、故障诊断、风机及反冲泵监控等功能。
单格滤池控制执行自动过滤监测滤池水位,根据滤池水位的情况及时调整出水阀的开度,使滤池保持在过滤水位。当运行周期到或强冲或水头损失以达到时,滤池进行自动反冲洗。单格滤池控制软件流程如图六所示。
三、 系统运行
笔架山水厂普通快滤池系统在投入运行五个月来,一直稳定可靠。见图七及图八所示滤池车间改造前后滤池控制柜比较。滤池水质也有所提高,且运行周期比过去延长50%。工人的劳动强度得到大幅降低,激发工人强烈的学习兴趣。系统的自诊断功能充分发挥作用,设备的维护率得到了很大提高。基本上能实现无人值守。
四、 结束语
现场总线技术,这种网络通信技术渗透于自动控制仪表和系统中的结果。在自动控制领域已经得到越来越多的应用,毋庸置疑,该技术具有广大前景。
