下面参照附图描述根据本发明实施例提出的供水管网内异物检测方法、装置及具有其的***，首先将参照附图描述根据本发明实施例提出的供水管网内异物检测装置。
图1是本发明一个实施例的供水管网内异物检测装置的结构示意图。
如图1所示，该供水管网内异物检测装置10包括：光纤传感器100、光电转换模块200和信号处理模块300。
其中，光纤传感器100用于检测供水管网中供水管道内壁的压力信号。光电转换模块200用于将供水管道内壁的压力信号转换为压力值。信号处理模块300用于根据压力值得到供水管网的当前压力分布状态，以识别管道内堵塞状态和/或淤泥厚度值。该装置10通过供水管网的当前压力分布状态实时检测管道内堵塞状态和/或淤泥厚度值，避免淤泥厚度过大而造成管道供水不正常和水压增加而造成的管道损坏，从而有效提高了检测的准确性、实时性和适用性，成本低且安装布置方便，简单易实现。
可以理解的是，本发明实施的装置10主要包括光纤传感器100、光电转换模块200和信号处理模块300，光纤传感器100用于实时感知供水管道内壁的压力分布，光电转换模块200将压力值转换为压力信号之后，把压力信号上报至信号处理模块300，信号处理模 块300对感知的压力信息进行处理、分析和推断，进而识别管道内压力分布异常状态并推断管道内堵塞和淤泥厚度值，其中，管道内堵塞和淤泥厚度值的示意图如图2所示。
具体而言，在本发明的一个实施例中，光纤传感器可以理解为光纤，即言可以优选通过光纤监测淤泥厚度，即光纤就是传感器，应用光纤测量压力连续性，可以分层测量不同厚度的压力，进而反映管道堵塞和淤泥厚度。
本发明实施例的装置将光纤至于管道内，从而可以准确测量管道内壁处压力，简单易实现。
进一步地，光电转换模块200可以为光电转换器，信号处理模块300可以为监测主机，监控主机应用模式识别与分类算法实现对城市供排水堵塞与淤泥厚度的监测。
下面将结合具体实施例对供水管网内异物检测装置进行进一步阐述。
进一步地，在本发明的一个实施例中，本发明实施例的装置10还包括：至少一个固定装置。其中，至少一个固定装置固定设置于管道内壁上，以固定光纤传感器100。
可以理解的是，固定装置也可以称为传感器固定装置，主要用于将光纤传感器100(即光纤)固定于管道内壁内。
另外，光纤传感器100可以固定在预先设计的光纤支架上，并安装在紧贴管道内壁；监测的为传输管道，分布范围根据实际情况而定，在此不做具体限定。光纤传感器100可以以弧形铺设供排水管道内，传感器将在下水道内压力监测信号传送到光电转换模块200。
具体而言，光纤传感器100包括淤泥厚度检测光纤传感器和管道堵塞光纤传感器，下面分别对两种传感器进行详细阐述，具体包括：
(1)淤泥厚度检测光纤传感器主要布置于弧形支架紧贴管道内壁处，当管道有淤泥时，在淤泥厚度检测光纤传感器处所产生的压力分布于正常压力有明显区别，通过检测管道内壁压力值的大小和分布，识别管道出现淤泥厚度情况。
如图3所示，淤泥厚度检测光纤传感器置于凹形的固定栏上，当管道内出现淤泥时，淤泥堆积在管道内的光纤上，造成通过光纤的光发生变化，通过光电转换器转换为压力信号，监控主机通过分析压力信号的变化，识别与分类淤泥厚度层的变化，进而确定管道淤泥厚度。
(2)管道堵塞光纤传感器置于弧形支架上，并占管道近三分之一空间，中间镂空，便于水的流动，当有异物占用管道时，道堵塞光纤传感器所采集的压力不同，识别异物堵塞状况。
如图4所示，管道堵塞光纤传感器识别异物堵塞的原理为：主要以管道堵塞光纤传感器承受压力分布不同，实现管道内的堵塞状态分析、监测。管道堵塞光纤传感器至于弧形的固定栏上，管道内的水流经管道堵塞光纤传感器造成光纤光信号发生改变，通过识别光 信号的变化不同，感知管道内的堵塞状态。
进一步地，如图5所示，本发明实施例实现堵塞和淤泥厚度两个光纤的并联连接，并分别经过光电转换器转换为堵塞压力信号和淤泥厚度的压力信号的变化。需要说明的是，光纤属于无源传感器，且市面常用，安装时只需布置于安装支架上，因此，布置安装方便，成本低。
进一步地，在本发明的一个实施例中，本发明实施例的装置10还包括：信号收发装置。其中，信号收发装置，用于发送压力分布状态、堵塞状态和/或淤泥厚度值。
可以理解的是，信号收发装置负责把监控的状态信息上报至监控中心，及时显示和通知管道内淤泥对管道供水的影响。
进一步地，在本发明的一个实施例中，本发明实施例的装置10还包括：报警模块。其中，报警模块，用于在淤泥厚度值大于预设值时，发送报警信息。
可以理解的是，预设值可以根据实际情况进行设置，在此不做具体限定。本发明实施例在检测到淤泥厚度值过大时，发送报警信息，以通知相关人员对淤泥进行及时的清理，避免淤泥厚度过大而造成管道供水不正常和水压增加而造成的管道损坏，从而有效保证排水管道畅通。
综上，本发明实施例应用光纤即上述的光纤传感器布放至供排水管道中，以信号处理与模式识别的方案实时监测供排水管道堵塞和淤泥厚度，从而有效解决了大型供水管网内异物堵塞和淤泥检测困难、定位不准确的难题，并具有实时、精度高、适用范围广、安装布置方便、成本低的优点。
根据本发明实施例提出的供水管网内异物检测装置，通过光纤检测供水管网的当前压力分布状态实时检测管道内堵塞状态和/或淤泥厚度值，避免淤泥厚度过大而造成管道供水不正常和水压增加而造成的管道损坏，从而有效提高了检测的准确性、实时性和适用性，成本低且安装布置方便，简单易实现。
