本申请涉及搅拌站技术领域，具体而言，涉及一种物料含水率检测系统、一种物料含水率检测方法及包括该物料含水率检测系统的搅拌站。
目前，在混凝土搅拌站的设计过程中，控制系统设置的混凝土配合比是按砂石骨料等材料都是干燥状态下的，在搅拌站实际生产制造过程中，砂石骨料受货源供应、存储方式以及季节气候的影响，会具有不同的含水率。砂石骨料含水率对混凝土单方用水量影响较大，而在混凝土配制过程中，水和水泥的比值决定了混凝土的强度和耐久性，砂石骨料的含水率变化决定了补水的用量，因此对砂石含水率进行检测、及时对混凝土配合比进行调整具有重要意义。

其中，图1和图2中的附图标记与部件名称之间的对应关系为：
1在线含水率检测系统，10配料装置，20配料仓门开闭机构，301平皮带机，302斜皮带机，40在线含水率检测装置，50工控机。
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1和图2描述根据本申请一些实施例所述的物料含水率检测系统、物料含水率检测方法及搅拌站。
如图1所示，本申请第一方面的实施例提供的物料含水率检测系统1，包括：配料装置10，包括多个配料仓；物料输送装置，用于将各个配料仓内的物料分别向外输送；在线含水率检测装置40，设置在物料输送装置的输送通道上，在线含水率检测装置40用于检测通过输送通道的物料的含水率，在线含水率检测装置40为非接触式在线水分检测仪，如近红外线非接触式在线水分检测仪，具体可选为哈尔滨宇达电子技术有限公司生产的HYD-8B近红外线非接触式在线水分检测仪。
本申请第一方面的实施例提供的物料含水率检测系统，通过在物料输送装置的输送通道上设置一套非接触式的在线含水率检测装置40，由于各个配料仓内的物料分别通过输送通道向外输送，因此在线含水率检测装置40能够实时检测各个配料仓内的物料的含水率，该物料含水率检测系统，物料不会与在线含水率检测装置40产生接触，使在线含水率检测装置40不会受到物料的冲击，从而有效提高了在线含水率检测装置40的使用寿命，且由于只需设置一套在线含水率检测装置40即可，因此大大降低了成本。
进一步地，物料输送装置包括平皮带机301和斜皮带机302，各个配料仓的下料口设置在平皮带机301的上方，平皮带机301的输出端设置在斜皮带机302的输入端的上方，斜皮带机302的输出端用于与搅拌系统相连，在线含水率检测装置40设置在斜皮带机302上，如图1所示。
物料输送装置包括平皮带机301和一端与平皮带机301的一端相连的斜皮带机302，由于配料仓的结构一般为地坑式，因此配料仓到搅拌系统之间存在高度差，通过将平皮带机301设置在配料仓的下方，便于水平运输配料仓所卸物料，将斜皮带机302的另一端与搅拌系统相连，从而使平皮带机301上的物料能够通过斜皮带机302输送至搅拌系统进行搅拌，结构较为简单，有助于提高输送效率并降低生产成本。
本申请第二方面的实施例提供了一种搅拌站，包括：工控机50；第一方面的实施例中任一项的物料含水率检测系统；其中，工控机50与在线含水率检测装置40电连接，工控机50用于根据在线含水率检测装置40反馈的含水率分别计算各个配料仓所输出物料的含水量，并根据各物料的含水量调整混凝土的配合比。

进一步地，在线含水率检测装置40包括无线通讯装置(图中未示出)，无线通讯装置与工控机50电连接，以将在线含水率检测装置40检测到的物料的含水率反馈至工控机50。
在线含水率检测装置40包括无线通讯装置，如通过WIFI或蓝牙连接，通过将无线通讯装置与搅拌站系统工控机50电连接，从而使在线含水率检测装置40能够将检测到的含水率数据实时反馈至搅拌站系统工控机50。
进一步地，在实施例一的基础上，进一步地，各个配料仓的下料口处还包括：配料仓门开闭机构20，配料仓门开闭机构20的控制端与工控机50电连接，从而能够在接收到工控机50的控制指令时打开或关闭对应的配料仓的下料口处的仓门，以打开或关闭对应的配料仓的下料口处的仓门。
各个配料仓的下料口处还包括与工控机50电连接的配料仓门开闭机构20，配料仓门开闭机构20能够在接收到工控机50的控制指令时打开或关闭对应的配料仓的下料口处的仓门，以保证配料仓能够连续自动卸料，提高搅拌站的工作效率。
进一步地，各个所述配料仓上分别设置有用于检测仓门开闭状态的感应开关，所述感应开关与所述工控机50电连接，所述感应开关用于将对应的配料仓的仓门开闭状态反馈至所述工控机50，使所述工控机50控制其他所述配料仓中的一个配料仓的配料仓门开闭机构20打开仓门进行卸料。
各个配料仓还分别设置有用于检测仓门开闭状态的感应开关，通过将感 应开关与工控机50电连接，感应开关能够实时检测各个配料仓内的仓门的开闭状态，并及时反馈至工控机50，使其能够控制其他配料仓中的一个配料仓的配料仓门开闭机构20打开仓门进行卸料，以保证卸料的连续。
如图2所示，本申请第三方面的实施例提供了一种物料含水率检测方法，适用于第一方面的技术方案中任一项所述的在线含水率检测系统，包括：步骤S102：实时获取配料仓输出的流经在线含水率检测装置40的物料的含水率；步骤S104：获取配料仓内的物料经过在线含水率检测装置40的时间段；步骤S106：选取时间段内的含水率数据，作为与之对应的配料仓内的物料的含水率。
本申请第三方面的实施例提供的物料含水率检测方法，通过实时获取配料仓输出的流经在线含水率检测装置40的物料的含水率，再通过获取配料仓内的物料经过在线含水率检测装置40的时间段，即通过选取该时间段内的含水率数据，并将其作为与其相对应的配料仓内的物料的含水率，进而能够得出每个配料仓内物料的含水率，便于根据每个配料仓内的物料的含水率来调整每个配料仓内物料含水的重量，进而调整补水的重量以调整混凝土配合比。
进一步地，获取配料仓内的物料经过在线含水率检测装置40的时间段，具体包括：获取配料仓内的物料到达在线含水率检测装置40的第一时刻；获取配料仓内的物料完全通过在线含水率检测装置40的第二时刻；根据第一时刻和第二时刻确定配料仓内的物料经过在线含水率检测装置40的时间段。
获取配料仓内的物料经过在线含水率检测装置40的时间段具体包括：获取配料仓内的物料到达在线含水率检测装置40的第一时刻，再获取配料仓内的物料完全通过在线含水率检测装置40的第二时刻，根据第一时刻和第二时刻确定配料仓内物料经过在线含水率检测装置40的时间段，即从配料仓内的物料到达在线含水率检测装置40时至配料仓内的物料完全通过在线含水率检测装置40之间的时间段内所检测的含水率为与其相对应配料仓内的物料的含水率。
进一步地，记第一时刻为T1，第一配料仓打开的时刻为t1，第一配料仓与在线含水率检测装置40之间的距离为S1，物料输送装置的运行速度为 V，T1与t1、S1、V之间满足：T1＝t1+S1/V；和/或，记第二时刻为T2，第二配料仓打开的时刻为t2，第二配料仓与在线含水率检测装置40之间的距离为S2，物料输送装置的运行速度为V，T2与t2、S2、V之间满足：T2＝t2+S2/V。
