Description
技术领域
本发明的对象是能够测量静电场的传感器和用于家庭的安全系统。本发明在安全部门以及更具体地在私人或家用财产安全方面具有其实际应用,本发明的主要目的为通过门、窗或栅栏的侵入检测——但是其可以用于其他位置例如墙体或隔断墙。
背景技术
目前,在针对室内空间的私人安全的领域中,使用了能够检测侵入家庭或类似事件的不同类型的设备。以下为不同类型的检测设备:
(a)体积传感器,其检测测量区域的体积改变并且将它们转变为运动检测。
(b)开门传感器,其检测门或窗何时被打开或关闭。
(c)红外屏障传感器,其检测对象在其发射器与接收器之间的通过。
(d)振动或玻璃破碎传感器,其检测在晶体被击打或遭受破碎时晶体中的振动。
所有这些设备共同之处在于:均被安装在房屋内。因此,因为它们仅能够在侵入已经发生时检测到该侵入,所以它们均不提供预防性的安全。因此,其不是预防性安全系统,而是事件警告或警报系统。另一方面,体积传感器和红外屏障传感器二者均不能另外区分移动对象的类型或其范围内发生的不同移动。
为了避免这些问题,最佳解决方案为静电场传感器。然而,大多数文献是基于不受控制的信号以及基于对取决于信号的共振频率和/或其阻抗的变化的容量(capacity)的间接测量。
例如,文献ES2152335T3描述了连接至天线的检测器设备,所述天线用于检测围绕天线的电场或电磁场的小的电容性的改变,所述设备包括:产生装置,其用于产生围绕所述天线的电场或电磁场;平衡装置,其用于将所产生的围绕所述天线的电场或电磁场维持在平衡状况下;过滤装置,其用于防止检测器设备被温度和湿度的改变所影响;检测装置,其用于检测所产生的围绕所述天线的电场或电磁场的小的改变;以及指示装置,其用于指示电场或电磁场的改变已经发生,所述设备的特征在于:产生装置为方波产生器,该方波产生器优选地产生在50Hz与5000Hz之间的方波;并且特征在于来自所述产生器的未受影响的方波和受到围绕天线的场的电容性地影响的方波被馈送至放大器装置以放大其之间的差异。
由于该检测器设备,实现了在第一存在区域、第二存在区域和第三存在区域中的安全系统,其中,第一存在区域指示侵入者已经以100cm与150cm之间的距离靠近保护对象,第二存在区域指示侵入者已经以30cm的距离靠近受保护的对象,第三存在区域指示侵入者几乎接触到保护对象。
因此,本发明创建方波,其中,根据方波的频率的变化,可以计算相关的容量。该信号在导体中创建不受控制的磁场——即磁场的场线沿所有方向延伸并且此外随着温度、湿度和其他条件而经历变化,所以需要校正这些问题。
发明内容
本发明的对象是一种传感器,该传感器能够测量在充当电极或天线的探针周围的静电场中由于人类出现于其附近而发生的扰动。该静电场还以受控制的方式被重定向以将它们的影响集中于某一区域。另外,传感器能够基于改变的量值将人与其他生物或材料对象进行区分。
反过来,该传感器是安全系统的组成部分,该安全系统通过传感器、无线通信设备和中央警报管理的集成被设计成对进入定界空间的侵入的预防性检测。
更具体地,在本发明的第一方面,静电场传感器的特征在于:其包括两个静电场测量电路,两个静电场测量电路的信号通过去耦电路相对于彼此被去耦;以及其中,所述静电场测量电路通过相位测量电路与包括同轴电缆的天线相连。
在本发明的第二实际实施例中,静电场和磁场传感器的特征在于使用了具有小于5MHz的工作频率的调谐器电路。该电子电路被划分成的部分可以是:RLC振荡电路和相位稳定电路。传感器具有连接至所述电路以充当天线并且产生静电场的传播的同轴电缆。所述天线可以具有若干层电极以控制所产生的场的影响区域。
在本发明的第二方面,用于内部和外部空间的安全系统包括至少一个上述的静电场传感器,静电场传感器连接至信号调节器电路和处理器,处理器包括存储器,该存储器至少包含具有指令的软件,所述指令被配置成:检测从传感器接收的静电场的变化;确定已经引起静电场的变化的对象的体积和密度;以及证实对象的体积和密度是否对应于非授权侵入并且向配电盘发出加密信号。
最后,在本发明的第三方面,要求保护一种用于检测家庭中的侵入者的方法,该方法包括以下步骤:(a)至少用上述的静电场传感器来检测静电场的变化;(b)确定已经引起静电场的变化的对象的体积和密度;(c)证实对象的所述体积和密度是否对应于非授权侵入;以及(d)发出警报加密信号。
本发明是基于本发明的传感器对象的容量来测量存在于充当探针或天线的导体——在本发明的情况下导体为同轴电缆——的周围的静电场在所述场被带电体例如人体的作用所影响时的变化。
人体像任意其他存在对象一样具有其自己的电特性,该电特性取决于材料、密度、体积、温度和导电性。不同对象之间的电势差在它们彼此相接触或接近时导致一个对象与另一对象的静电相互作用。本发明的传感器对象使用该效应,实现对所述场在连接至其的电子电路中引起的波动的连续测量。该电路通过场量值的改变能够区分不同类型的主体或对象并且能够将人类存在与另一材料或动物存在相区别。
事实上,本发明的传感器对象在执行对容量的连续测量时,其形成天线上产生的并且通过无限场线的电场,连接至传感器的处理器使得能够确定引起天线上的场波动的材料的体积和密度。
本发明应用于家庭中的安全系统,提供了前瞻地检测在门、窗和栅栏中的侵入的能力——即侵入发生之前的检测能力。
在整个本说明书和权利要求书中,词语“包括”及其变型并不意在排除其他技术特征、添加物、部件或步骤。对于本领域技术人员,本发明的其他目的、优点和特征将会部分地根据说明书显现以及部分地根据对本发明的实践显现。下文的示例和附图是为了说明而被提供,并不意在限制本发明。此外,本发明涵盖本文所示出的特定和优选实施例的所有可能的组合。
附图说明
以下是对一系列附图的非常简要的描述,其中,附图帮助提供对于本发明的较好的理解并且附图与所述本发明的作为其非限制性示例呈现的实施例明显相关联。
图1示出本发明的静电场传感器对象的方案。
图2示出本发明的安全系统对象的方案。
图3示出本发明的静电场传感器对象的第二实施例。
具体实施方式
如图1中可见,静电场传感器包括天线1,该天线1由具有一条导线、两条导线或三条导线的同轴电缆构成。天线1与相位测量电路2直接相连,相位测量电路2是对与相位测量电路2相连的两个静电场计量器(3、4)的信号进行测量和分析的电路。静电场计量器(3、4)通过去耦电路5被彼此去耦,使得虽然相应的电流I1和I2不同,但是两个计量器(3、4)之间的电势差为零。
然而,如图3所示,本发明的静电场传感器对象包括第二实际实施例,其中,天线1连接至具有小于5MHz的工作频率的包括RLC电路31和相位稳定电路32的调谐器电路。
如在第一实施例中,天线1为连接至所述调谐器电路(31、32)的同轴电缆并且还被配置成产生电场和磁场的传播。该天线可以具有多层电极以控制所产生的场的影响区域。
因为天线1的有源同轴线(coaxialactive)是闭合的,所以在导体中产生的磁场被限制并且因此可以在期望的地方创建场,例如在门、窗或墙中。
图2示出本发明的安全系统对象的示意图,该安全系统对象包括如图1或图3所描绘的静电场传感器,静电场传感器与信号调节器电路6——信号调节器电路6实质上为模数转换器——相连,信号调节器电路6转而连接至处理器7,处理器7被配置成检测静电场的变化,处理器7建立关于这样的变化的一种三维图,处理器7能够确定已引起所述变化的对象的体积和密度。
该处理器7转而连接至射频电路8,该射频电路8朝向控制整个设施(installation)的配电盘9发出加密信号。
另外,处理器7连接至安全相机10,该安全相机10对由处理器7检测到的并且定义为非授权侵入的对象进行记录。
最后,处理器7优选地经由蓝牙与用户识别装置11相连,以使授权系统用户能够进入场所而不产生警报信号。
