Description

独立整装的、有浮力的且不透水的无线洪水探测器
技术领域
[0001]本申请属于流体探测器,以提供感兴趣区域内的洪水指示器。更具体地,本申请属于这样的探测器,其是独立整装的,并且可以与监测感兴趣区域内的不同状况的系统进行无线通信。
背景技术
[0002]已知用于对于各种预定状况的存在监测感兴趣区域的多种系统。这些状况包括入侵、玻璃破碎、烟、火灾、湿度、温度,全都没有限制。有时,希望监测流体存在的区域,例如洪水存在的区域。
[0003]已知类型的洪水探测器具有一个或两个部件的设计。一个部件设计是没有浮力的,并且被设计为如果洪水上升到高于传感器则是能够浸入水中的。因此,这样的产品通常不是无线的,因为当被浸没时,无线性能将会是相当弱的。
[0004]存在于无线市场的典型的两部件产品包括探头和独立的发送器,在探头和发送器之间具有导线。这种类型的产品的安装包括用螺钉将探头连接在待监测的区域。然后,远离探头一定距离安装发送器,并且导线在探头与发送器之间布线。发送器远离探头安装,以保护其远离水并且确保探头不会被浸没,导致其不起作用。
[0005]上述过程是耗时的。它可能与安装者安装整个监测系统耗费时间的一样多。此外,这种类型的产品不能邮寄给业主用于自己安装。
[0006]期望的是可获得无线洪水探测器,其可以容易地安装,无需特别的安装技能或说明。
[0007]附图简要说明
[0008]图1图示了根据本发明的洪水探测器;
[0009]图2是图1的探测器的底视图;
[0010]图3是图1的探测器移除盖后的整体视图;
[0011 ]图4是图1和图3的探测器的侧视截面图;以及
[0012]图5图示了在流体中漂浮的本发明的探测器。
[0013] 详细说明
[0014]虽然公开的实施例可以采取许多不同形式,但在附图中示出特定实施例并且在这里将进行详细描述,应该理解为本公开被认为是其原理的范例以及实践该原理的最好方式,并且其并不意在限制本申请或者对于示出的特定实施例的权利要求。
[0015]在公开的实施例中,无线洪水探测器被配置为具有单个壳体。流体或洪水探头,或流体或洪水电极,在顶部或底部或两者被模制到壳体中。探测器是有浮力的,以便保持电子器件(无线电设备、天线,等)在水面以上并且是可操作的。安装容易如只需将其放置在监测洪水的区域中。有利地,在公开的探测器中,传感器、无线电设备以及洪水探头安装在单独的、不透水的、有浮力的壳体中。
[0016]壳体优选由有浮力的材料制成,例如,具有气穴(或泡沫)的塑料。模制到该壳体中的是两个流体感测电极,位于可以接触到待监测的区域的一侧或两侧上。
[0017]优选的实施例具有圆盘状的形状。两个电极可以位于圆盘的顶部并且两个电极可以位于圆盘的底部。应该理解的是,其它壳体形状也在本发明的精神和范围内。例如,也可以使用球状壳体。
[0018]在圆盘内部存在控制电路和无线发送器。在一个实施例中,可以使用霍尼韦尔型号为5816的发送器。控制电路可以连接到电极。连接到发送器的天线可以安装到圆盘的中心,使得其位于水面以上,不管圆盘相对于流体例如水的定向。
[0019]当位于圆盘任一侧的电极浸入到水中时,可以探测到水的存在。消息可以被无线发送到移动控制面板。
[0020] 为了安装这种探测器,安装者首先通过将探测器浸入在水中或者通过用导线或螺丝刀使两个电极短路,将洪水圆盘的序列号登记到控制面板。一旦被登记,安装者就可以识别用于洪水监测的区域,并且将洪水圆盘放置在该区域中。当有洪水时,电极将被浸入到水中并且发送警告指示信号到控制面板。如果水上升,洪水圆盘将漂浮在水面上,保持电子器件干燥以及天线位于水面以上,从而确保持续操作。
[0021]附图示出了本发明实施例的各个方面。流体探测器10包括圆柱形盘状壳体12,圆柱形盘状壳体12具有上表面12a,封闭的边界侧壁12b以及下表面12c。壳体12是封闭的并且是不透水的。
[0022]如图3所示,壳体12包括可移除的盖16a以及限定内部区域16c的基底部分16b。当盖16a例如通过螺纹或搭扣配合可移除地连接到基底16b时,形成包括内部区域16c的封闭干燥内部区域。可以理解的是,可以采用其它的壳体形状,以及将盖16a连接到基底16b的其它结构,而不脱离本发明的精神和范围。
[0023] 壳体12可以承载包括印刷电路板22a的电子器件封装20。电路板22a支承为控制电路22c提供电能的可更换电池22b,传感器接口电路22d以及发送器或收发器22e,在图4中最佳可见。
[0024]电极或传感器24a、b可以承载在表面12c上,位于壳体12外部,暴露于局部流体F,如图2所示。电极24a、b可以模制到壳体12的下部16b并且通过表面12c中的阻止流体进入的密封端口以及导体24-1、24-2连接到区域16c中的传感器接口电路22d。
[0025] 第二组电极24c、d可以形成在壳体12的上表面12a上,同样通过导体24_3、24_4连接到传感器电路22d。本领域技术人员可以理解,使用的准确类型的流体传感器和到接口电路22d的导体的结构都不表示对本发明的限制。
[0026]第一和第二天线部分26a、b被承载在印刷电路板22a上/由印刷电路板22a承载,并且连接到收发器22e。天线26a、b被配置为使得当探测器10漂浮在流体F中时,天线中的一个总是在流体液面Fl以上,从而便于与移动监测控制单元或面板30无线通信。
[0027]图5图示了漂浮在流体F中的探测器10。有利地,当两表面12a和12c都承载流体传感器时,例如24a...C,假定是上述的天线结构,那么流体F中的探测器10的定向是不相关的。因此,安装者仅仅需要将探测器10放置到流体可能聚集的区域,而无需关注其定向。
[0028]总之,洪水探测器包括承载外部流体传感器的可漂浮的独立整装的壳体。连接到传感器的控制电路,以及发送器可以承载在壳体中。探测器可以与移动监测系统控制单元或面板无线通信。
[0029]连接到发送器的天线承载在壳体中。当壳体漂浮在流体中时,壳体的一部分位于流体的上表面以下,并且一部分位于该上表面以上。壳体被配置为使得天线位于流体上表面以上,以当探测器漂浮在流体中时,改进与移动控制面板的无线通信。
[0030]更进一步的,可以理解的是,被感测的流体的类型在此不作为限制。天线与流体表面的相对位置优选在流体顶部以最小化RF(射频)衰减。最后,壳体仅仅需要是足够长的防流体的以发送指示流体已经被感测到的传输。
[0031]根据前面的内容,可以注意到,在没有脱离本发明精神和范围的情形下,可以实施多种变形和修改。应当理解的是,这里描述的特定装置没有意在或者应当暗示任何限制。当然,其意在通过附属的权利要求覆盖落入权利要求范围的所有这种修改。此外,附图中描述的逻辑流程并不要求示出的特定顺序,或者次序来实现理想的结果。根据描述的流程,可以提供其它步骤,或者可以删除一些步骤,以及根据描述的实施例,可以加入或去掉其它一些部件。
