附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的在线监测系统的结构示意图。
图2是本发明另一实施例提供的在线监测系统的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，本发明实施例的在线监测系统10包括在线监测仪101、电源线102、第二采样管103、自吸泵104、第一采样管105、巴氏槽106、排液管107和补液装置11。
其中，在线监测仪101与自吸泵104通过电源线102电连接，在线监测仪101控制自吸泵104的启动或关闭。同时，在线监测仪101能够对采样的待测样品进行检测，以监测污染状况。第二采样管103连接自吸泵104的出液口与在线监测仪101，第一采样管105连接自吸泵104的进液口与巴氏槽106，排液管107连通在线监测仪101与巴氏槽106。由此，自吸泵104在在线监测仪101的控制下启动工作，通过第一采样管105从巴氏槽106中抽取待测样品，并通过第二采样管103将待测样品输入到在线监测仪101中。在线监测仪101对待测样品进行检测之后，将样品废液通过排液管107排至巴氏槽106中。本实施例中，使用巴氏槽来容纳待测样品；在其他实施例中，可以使用其他容纳器来容置待测样品。
当第一采样管105内待测样品的液位过低时，自吸泵104将无法工作，从而导致在线监测仪101的监测数据异常。而补液装置11能够对第一采样管105内的待测样品进行补充，保证自吸泵104的正常工作。
本实施例中，补液装置11包括信号线108、液位传感开关109、电源线110、潜水泵111和补液管112。在其他实施例中，补液装置可以包括其他的组成部件，只要补液装置整体上起到补充待测样品、保证自吸泵的正常工作即可。
本实施例中，液位传感开关109通过电源线102与在线监测仪101电连接，在线监测仪101控制液位传感开关109的供电。液位传感开关109与潜水泵111之间设有电源线110，液位传感开关109通过电源线110控制潜水泵111的开闭。液位传感开关109与第一采样管105之间设有信号线108，通过信号线108，液位传感开关109能够监测到第一采样管105内待测样品的液位。液位传感开关109中预设有预定液位值。所述预定液位值是能够保证自吸泵104正常工作的第一采样管105中待测样品应达到的液位值，所述预定液位值根据 实际情况予以确定。本实施例中，液位传感开关109包括但不限于电容式液位开关、浮球式液位开关、电子式液位开关、超声波液位开关或音叉液位开关。
潜水泵111置于巴氏槽106内，用于抽取巴氏槽106中的待测样品。潜水泵体积小、结构紧凑且可靠性高。在其他实施例中，可以使用其他泵单元来替代潜水泵。潜水泵111与采样管105之间设有补液管112，潜水泵111将抽取的待测样品泵入补液管112，待测样品通过补液管112流入采样管105中。
本实施例的在线监测系统10工作时，液位传感开关109监测第一采样管105内待测样品的液位。当第一采样管105内待测样品的液位值低于预定液位值时，自吸泵104无法正常工作。此时，液位传感开关109启动潜水泵111，潜水泵111开始从巴氏槽106中抽取待测样品，并将待测样品泵入补液管112。补液管112中的待测样品流入第一采样管105，使得第一采样管105中的待测样品的液位上升。当第一采样管105中的待测样品的液位值达到所述预定液位值时，液位传感开关109关闭潜水泵111，潜水泵111则停止抽取待测样品，第一采样管105中的待测样品不再增加。由此使得所述待测样品的液位保持为所述预定液位值，从而保证自吸泵104能够正常工作。
由此，本实施例的在线监测系统10，通过设置补液装置11，补液装置11能够在第一采样管105中的待测样品的液位值低于所述预定液位值时，向第一采样管105中补充待测样品以保证自吸泵104正常工作，从而保证污染源在线监测系统10能够正常、可持续的进行监测。
如图2所示，在本发明的另一实施例中，与上述实施例不同的是，在线监测系统12中，补液装置13还包括一过滤单元113，过滤单元113能够对待测样品中的杂质进行清洁过滤。过滤单元113设于潜水泵111与巴氏槽106之间，且过滤单元113的一端连通潜水泵111，另一端连通巴氏槽106。巴氏槽106中的待测样品先经过滤单元113，然后被潜水泵111抽取，由此避免待测样品中的杂质堵塞潜水泵111。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
