技术领域
本公开涉及自动化控制领域，更具体地涉及一种负载控制装置以及包括该负载控制装置的无线负载控制系统。
背景技术
随着自动化控制在民用和商用领域的广泛应用，负载控制装置在楼宇配电系统、智能家居系统中起到日益重要的作用，因此负载控制装置也面临着更高的要求。
现有的一些负载控制装置作为特定负载(例如断路器、接触器等)的专用辅助模块来设计，其必须紧邻负载设置，并且与负载之间的连接往往通过导电搭扣等形状配合部件来实现。这导致负载控制装置的通用性和空间配置上的灵活性大大降低。
在目前的负载控制装置中，负载控制装置与中央控制器采取有线的通信连接，其接收来自中央控制器的控制指令并实现对负载状态的控制，从而实现负载的上电及断电过程。在这种设计中，负载控制装置的供电也需要借助和中央控制器之间的通信线来实现。这种取电方案布线较为繁琐，并且需要在通信线路和负载控制装置的电源模块中进行电源隔离，内部电路设计较为复杂。
实用新型内容
本公开针对上文提到的问题和需求，提出一种负载控制装置。其由于采取了如下文所述的特征而能够克服背景技术中提到的技术问题，且具有下文将介绍的其他优势。
本公开提出了一种负载控制装置，其包括：外壳，容纳在外壳中的电源 模块、通信模块、控制模块、输入端子和输出端子，其中所述电源模块电连接至所述通信模块和所述控制模块，为所述通信模块和所述控制模块供电，所述通信模块以无线的方式连接至网关设备，所述通信模块接收来自网关设备的中央控制命令并输出中央控制信号到所述控制模块，所述输出端子和输入端子通过导线电连接至负载，所述控制模块连接至所述通信模块，所述控制模块接收来自所述通信模块的中央控制信号，并根据该中央控制信号经由输出端子向负载输出状态控制信号，所述控制模块通过输入端子接收来自负载的状态信号，并将该状态信号经由通信模块发送至网关设备。
由此，负载控制模块可同时具备控制和监控功能。用户可以便捷地下达命令，控制负载的工作状态，也可以获知负载的状态信息，监控负载的运行状态。
在本公开中，为负载控制装置预留了可从外部接取的输出端子和输入端子，使得可以通过导线将负载至负载控制装置。由此，负载控制装置可用于控制任意负载，而不是作为特定负载的专用辅助模块存在，提高了负载控制装置的通用性。此外，采用导线连接的方案，使得负载控制装置不是必须紧挨着负载设置，大大地提高了空间配置的灵活程度，实现负载控制系统的合理布局。
进一步地，所述负载控制装置包括与所述控制模块电连接的按钮，所述外壳上设置有用于所述按钮的开口，所述按钮用于手动操作负载控制装置。
可选地，所述按钮根据其按下状态产生本地控制信号，所述控制模块根据本地控制信号向负载输出状态控制信号。该本地控制信号可特别有利地用于在紧急情况下需要立即切断负载的电连接的情形。该紧急情况例如为负载控制装置与网关设备或网关设备与用户模块无线连接丢失，导致负载控制装置接收到中央控制命令。按钮为负载控制装置提供了用户模块之外的额外的人机接口，使得可以紧急切断负载，确保用电安全。
可选地，所述按钮根据其按下状态产生退网信号，所述控制模块根据所述退网信号断开所述通信模块与所述网关设备的连接。在负载控制装置与网关设备通信不畅的情况下，用户可以手动地操作负载控制装置，使得负载控制装置主动离开网络，以重新执行入网操作，即重新将负载控制装置连接至网关设备。
进一步地，所述按钮包括按钮体和切换触头，所述切换触头根据按钮体 的按下状态切换其通断状态，所述按钮体包括按钮帽、从按钮帽周边凸出形成帽檐状的凸缘和触头致动部，所述凸缘在靠近外壳内带电部位的边缘包括弯折部，所述弯折部朝向远离所述带电部位的方向延伸。由于弯折部的存在，从用户操作位置到带电部位的爬电距离增加，加强了用户操作位置和带电部位之间的绝缘。
进一步地，所述按钮帽包括挖空部，所述挖空部朝向所述触头致动部一侧敞开。按钮帽形成空心的结构，其厚度被减薄，从而避免在按钮体的注塑成型过程中出现的缩孔、气泡等制造缺陷。
进一步地，所述外壳包括第一外壳部和第二外壳部，所述按钮体的触头致动部在与第一外壳部和第二外壳部接合的方向垂直的边缘处包括倒角。倒角可以起到导向的作用，防止在第一外壳部和第二外壳部接合操作期间按钮体和切换触点之间干涉的发生，有利于接合操作的顺利进行。
进一步地，所述凸缘包括按压引导槽，所述外壳在其内侧包括与所述按压引导槽配合的按压引导肋。借助按钮帽的按压引导槽和第二外壳部的按压引导肋的配合，按钮按下的操作可被引导，提高按压操作的稳定性。
进一步地，所述电源模块包括火线端子和零线端子，所述电源接口的火线端子和零线端子能够连接至接线母排。与现有技术中通过通信线取电的负载控制装置相比，本公开在负载控制装置中设置有带火线、零线端子的独立电源模块，可实现负载控制装置的灵活布置，降低了布线的复杂程度，并大大地简化了取电操作。此外，负载控制装置的内部也无需在通信线路及电源模块中进行电源隔离，从而简化了负载控制装置内部电路设计，减小了负载控制装置的体积和制造成本。此外，与接线母排的兼容性有利于接线美观，维护方便。
进一步地，所述负载控制装置包括与控制模块电连接的光学指示元件，所述外壳上设置有用于光学指示元件的开口，所述光学指示元件用于指示所述通信模块与网关设备的连接状态。由此，负载控制装置可以通过可视的形式通知用户负载控制装置与网络的连接状态。
本公开还提出了一种负载控制装置，其包括：外壳和容纳在外壳中的电源模块、通信模块、控制模块、输入端子和输出端子，其中所述电源模块电连接至所述通信模块和所述控制模块，所述通信模块与以无线的方式连接至网关设备，所述通信模块接收来自网关设备的中央控制命令并输出中央控制 信号，所述输出端子通过导线连接至负载，所述输入端子连接至本地控制器，所述控制模块连接至所述通信模块，所述控制模块接收来自所述通信模块的中央控制信号，并根据该中央控制信号经由输出端子向负载输出状态控制信号，或者所述控制模块通过输入端子接收来自本地控制器的本地控制命令，并根据该本地控制命令经由输出端子向负载输出状态控制信号。
由此，本地控制器可通过导线连接至输入端子，并设置在负载控制器外部的适当位置。由此，可为负载控制器的本地控制提供了额外的解决方案，以满足操作现场的不同需要。
本公开还提出了一种无线负载控制系统，其包括：用户模块，其接收用户输入的中央控制命令并以无线的方式输出所述中央控制命令；网关设备，其以无线的方式与所述用户模块通信连接，所述网关设备从用户模块接收中央控制命令并将所述中央控制命令以无线的方式输出；如前所述的负载控制装置，所述负载控制装置以无线的方式连接至所述网关设备，其中，所述负载控制装置接收来自网关设备的中央控制命令并根据该中央控制命令向负载输出状态控制信号，且其中，所述负载控制装置接收来自负载的状态信号，并将该状态信号经由通信模块发送至网关设备，所述网关设备将该状态信号输出至用户模块。

图1示出了根据本公开的一个实施例的负载控制装置10以及包括其的负载20控制系统的简化示意图。参照图1，该负载20控制系统包括用户模块40、网关设备30和负载控制装置10。
负载控制装置10(在图1中示出为虚线框内的部分)连接至要被控制的负载20。根据一个实施例，所述负载20例如可以是接触器、断路器以及脉冲开关等。所述负载20可安装于工业配电箱或家用配电箱中，其触点的一端连接至配电箱的供电电源，另一端可连接至外部用电设备。在其他的实施例中，所述负载20也可以是例如电机、传感器，也可以是家用负载20电路等。本公开的实施例不受负载20的具体类型的限制。
用户模块40被配置为接收用户输入的控制命令并以无线的方式输出所述控制命令。所述用户模块40可以为一个或多个专用或通用的计算机系统模块，例如个人电脑、笔记本电脑、平板电脑、手机、个人数码助理(personal digital assistance，PDA)及任何智能便携设备。本公开的实施例不受用户模块40的具体类型的限制。所述以无线的方式例如可以是通过以太网(Ethernet)、移动通信技术等。
所述网关设备30被配置为以上述无线方式从用户模块40接收中央控制命令并将所述中央控制命令以无线的方式输出。这里的无线方式例如是ZigBee通信。
负载控制装置10被配置为以无线方式接收来自网关设备30的中央控制命令并根据所接收的中央控制命令向负载20输出状态控制信号。
具体地，负载控制装置10可包括电源模块100、通信模块200和控制模块300。
所述电源模块100电连接至所述通信模块200和所述控制模块300，为所述通信模块200和所述控制模块300供电。
所述通信模块200以无线的方式连接至网关设备30，所述通信模块200接收来自网关设备30的中央控制命令并输出中央控制信号到所述控制模块300。
所述控制模块300连接负载20和通信模块200。
一方面，控制模块300可接收来自通信模块200的中央控制信号，并根据该中央控制信号经由输出端子620向负载20输出状态控制信号。响应于该状态控制信号，负载20中的触点可在打开状态和闭合状态之间切换。由此，用户可以通过用户模块40便捷地下达命令，控制负载20的工作状态。
另一方面，控制模块300还可接收来自负载20的状态信号，并将该状态信号经由通信模块200发送至网关设备30。所述网关设备30可进一步地将该状态信号输出至用户模块40。由此，用户可以通过用户模块40获知负载20的状态信息，监控负载20的运行状态。
以下参考图2和图3介绍根据本公开的负载控制装置10的机械结构设计。图2和图3分别以透视图和分解图的形式示出了根据本公开的一个实施例的负载控制装置10的组装状态和分解状态。
负载控制装置10具有外壳400，其包括大体为六面体形的主体400b和从主体400b的前部面凸出的鼻部400n。所述外壳400主体400b的后部面处可设置有上下两个插口和位于两个插口之间的凹部，用于将负载控制装置10安装至配电箱内部的导轨。在安装期间，所述凹部抵靠所述导轨放置，用于将负载控制装置10锁定至导轨的两个附接锁定器件700从上下两个插口中插入，通过弹性锁合的方式将负载控制装置10锁定安装至导轨。
所述外壳400可包括第一外壳部410和第二外壳部420。第一外壳部410和第二外壳部420可由塑料材料制成。第一外壳部410的内侧可设置有多个第一安装器件415，例如杆状的插销。第二外壳部420的内侧可设置有多个与第一安装器件415互补的第二安装器件425，例如圆筒状的接收部。通过沿着第二安装器件425的延伸方向移动第一安装器件415，使第一安装器件415接合并容纳在第二安装器件425中，从而实现所述第一外壳部410和第二外壳部420的接合。
外壳400内部容纳有印刷电路板250。印刷电路板250上承载有多个电子元器件。控制模块300(例如微处理器)以及通信模块200(例如Zigbee无线模块)布置在所述印刷电路板250上。
负载控制装置10可包括位于外壳400内部且可从外部接取的输入端子610和输出端子620。输入端子610和输出端子620连接至控制模块300(参见图4的实线部分)。根据图2和图3所示出的实施例，外壳400主体400b的下部设置有一对输入端子610，即第一输入端子611、第二输入端子612和一对输出端子620，即第一输出端子621、第二输出端子620。也可以根据需要，为负载控制装置10配备多对输入端子610和多对输出端子620。
外壳400可包括用于输入端子610和输出端子620的第三外壳部430。所述第三外壳部430位于外壳400主体400b的下部，且插置与第一外壳部410的下部和第二外壳部420的下部之间。所述第一外壳部410和第三外壳部430一起限定用于第一输入端子611和第一输出端子621的接收座。所述第二外壳部420和第三外壳部430一起限定用于第二输入端子612和第二输出端子620的接收座。
在一个实施例中，输入端子610和输出端子620可共同组成负载20接口。负载20连接至输入端子610和输出端子620。在这种情况下，一方面，控制模块300接收来自通信模块200的中央控制信号，并根据该中央控制信号经由输出端子620向负载20输出状态控制信号。响应于该状态控制信号，负载20中的触点可在打开状态和闭合状态之间切换。另一方面，控制模块300通过输入端子610接收来自负载20的状态信号，并将该状态信号经由通信模块200发送至网关设备30。
在一个示例性的实施例中，所述负载20例如为接触器。接触器包括主触点和辅助触点，所述主触点的两端可分别连接至负载控制装置10的输出端子620，所述辅助触点的两端可分别连接至负载控制装置10的输入端子610。由此，响应于控制模块300输出的状态控制信号，接触器中的主触点可在打开状态和闭合状态之间切换。辅助触点的状态与主触点的状态保持一致。由此，辅助触点的状态信号，也即主触点的状态信号可通过输入端子610反馈至负载控制装置10的控制模块300，并将该状态信号经由通信模块200发送至网关设备30。
输入端子610和输出端子620可以是已知类型的各种接线端子，例如螺帽接线端子，其包括螺帽接线柱、导线插座。所述导线插座中的电触点电连接至印刷电路板250，进而连接至其上的控制模块300。将两根导线的一端分别连接至负载20的两端，将两根导线的另一端分别插入一对输入端子610或 输出端子620的两个导线插座中，再旋紧螺帽接线柱使得导线与电触点保持紧密接触，即可将负载20与负载控制装置10的控制模块300连接。
在本公开中，为负载控制装置10预留了可从外部接取的输出端子620和输入端子610，使得可以通过导线将负载20至负载控制装置10。由此，负载控制装置10可用于控制任意负载20，而不是作为特定负载20的专用辅助模块存在，提高了负载控制装置10的通用性。此外，采用导线连接的方案，使得负载控制装置10不是必须紧挨着负载20设置，大大地提高了空间配置的灵活程度，实现负载20控制系统的合理布局。
在一个实施例中，所述输入端子610替代地连接至本地控制器50(参见图4的虚线部分)。所述本地控制器50例如为开关，本地控制器50可根据开关的按下状态产生本地控制命令。所述控制模块300通过输入端子610接收该本地控制命令，并根据该本地控制命令经由输出端子620向负载20输出相应的状态控制信号。由此，本地控制器50可通过导线连接至输入端子610，并设置在负载20控制器外部的适当位置。由此，可为负载20控制器的本地控制提供了额外的解决方案，满足操作现场的不同需要。
外壳400内部容纳有电源模块100，所述电源模块可从外部被接取。根据一个实施例，电源模块100设置于外壳400主体400b的上部。所述电源模块100由火线端子120和零线端子110组成。外壳400可包括用于电源模块100的第四外壳部440。所述第四外壳部440位于外壳400主体400b的上部，且插置与第一外壳部410的上部和第二外壳部420的上部之间。所述第一外壳部410和第四外壳部440一起限定用于零线端子110的接收座。所述第二外壳部420和第四外壳部440一起限定用于火线端子120的接收座。
火线端子120和零线端子110可以是已知类型的各种接线端子，例如螺帽接线端子，其包括螺帽接线柱、火线或零线插座。所述火线或零线插座中的电触点通过线束连接至印刷电路板250上的电源接口。将火线或零线插入插座中，旋紧螺帽接线柱使得火线或零线与插座中的电触点保持紧密接触，即可为印刷电路板250以及位于其上的通信模块200和控制模块300供电。有利地，根据本实新型的火线端子120和零线端子110可连接至梳状接线母排，使得接线美观，维护方便。
与现有技术中通过通信线取电的负载控制装置10相比，本公开在负载控制装置10中设置有带火线、零线端子110的独立电源模块100，可实现负载 控制装置10的灵活布置，降低了布线的复杂程度，并大大地简化了取电操作。此外，负载控制装置10的内部也无需在通信线路及电源模块100中进行电源隔离，从而简化了负载控制装置10内部电路设计，减小了负载控制装置10的体积和制造成本。
负载控制装置10可包括光学指示元件800，例如LED灯。所述光学指示元件800与印刷电路板250上的控制模块300电连接。负载控制装置10的外壳400的鼻部400n，更具体地，第二外壳部420上设置有用于光学指示元件800的开口，从而光学指示元件800从负载控制装置10外部可见。
光学指示元件800可通过变化闪烁频率或发光颜色等方式来指示所述通信模块200与网关设备30的不同连接状态。例如，在负载控制装置10正在执行入网操作(尝试连接至网关设备30)时，光学指示元件800发出以较高频率闪烁的绿光；当负载控制装置10稳定连接至网关设备30时，光学指示元件800持续发出绿光或发出以较低的频率闪烁的绿光；当负载控制装置10与网关设备30失去连接时，光学指示元件800持续发出红光。当然，根据本公开的光学指示元件800不限于上述发光方式。由此，负载控制装置10可以通过可视的形式通知用户负载控制装置80010与网络的连接状态。
负载控制装置10还包括按钮500，用于手动操作负载控制装置10。所述按钮500包括按钮体520和切换触头530，所述切换触头530根据按钮体520的按下状态切换其通断状态。外壳400鼻部400n的前部面处可设置有用于按钮500的开口。在图3所示的实施例中，所述开口设置在第二外壳部420上。按钮体520穿过所述开口设置。切换触头530设置在印刷电路板250上，并与控制模块300电连接。
根据本公开的一个实施例，按钮500可根据其按下状态产生本地控制信号，控制模块300根据该本地控制信号向负载20输出相应的状态控制信号。例如，当所述按钮500被按下时，控制模块300控制负载20，使得负载20中的触点从闭合状态至打开状态。该本地控制信号可特别有利地用于在紧急情况下需要立即切断负载20的电连接的情形。该紧急情况例如为负载控制装置10与网关设备30或网关设备30与用户模块40无线连接丢失，导致负载控制装置10接收到中央控制命令。按钮500为负载控制装置10提供了额外的人机接口，使得可以紧急切断负载20，确保用电安全。
根据本公开的另一个实施例，按钮500根据其按下状态产生退网信号， 所述控制模块300根据所述退网信号断开所述通信模块200与所述网关设备30的连接。根据一个实施例，退网信号可以在长按该按钮500的情况下产生。在负载控制装置10与网关设备30通信不畅的情况下，用户可以手动地操作负载控制装置10，使得负载控制装置10主动离开网络，以重新执行入网操作，即重新将负载控制装置10连接至网关设备30。
图5和图6示出了按钮体520的具体结构。按钮体520大体上由三部分组成：在按钮体520的前部呈凸台状的按钮帽521、从按钮帽521后部周边凸出形成帽檐状的凸缘522和位于按钮体520后部的触头致动部523。
图7示出了按钮体520装配至外壳400的状态。按钮帽521安装为从外壳400的内部穿过外壳400上的开口朝向负载控制装置10的外部突出。凸缘522和触头致动部523位于外壳400的内部。触头致动部523朝向外壳400的内部突出且与按钮500的切换触头530相对。
凸缘522可包括第一侧边522a、第二侧边522b、第三侧边522c和第四侧边522d。
在安装位置，第一侧边522a靠近印刷电路板250的带电部位。由于印刷电路板250通过火线和零线高压供电，需要特别地确保用户操作按钮500时的用电安全。为此，凸缘522在第一侧边522a包括弯折部524，该弯折部524朝向远离所述带电部位的方向延伸。由于弯折部524的存在，从用户操作位置到带电部位的爬电距离增加(如图7中的虚线路径所示)，加强了用户操作位置和带电部位之间的绝缘。
返回参考图6，按钮帽521包括挖空部525，所述挖空部525朝向所述触头致动部523一侧敞开。按钮帽521形成空心的结构，其厚度被减薄，从而避免在按钮体520的注塑成型过程中出现的缩孔、气泡等制造缺陷。
此外，按钮体520的触头致动部523在与第一外壳部410和第二外壳部420接合的方向垂直的边缘处包括倒角526。在第一外壳部410和第二外壳部420接合操作之前，按钮体520已经被装配至第二外壳部420，而印刷电路板250已经被装配置第一外壳部410。在接合操作期间，按钮体520可能发生轻微地晃动而偏离其初始位置，导致按钮体520和连接至印刷电路板250上的切换触点发生干涉。倒角526可以起到导向的作用，防止按钮体520和切换触点之间干涉的发生，有利于接合操作的顺利进行。
按钮帽521的第二侧边522b设置有缺口形状的按压引导槽528。与此相 对应地，第二外壳部420可在其内侧包括与所述按压引导槽528互补的按压引导肋428(图8)。借助按钮帽521的按压引导槽528和第二外壳部420的按压引导肋428的配合，按钮500按下的操作可被引导，提高按压操作的稳定性。
上文中参照优选的实施例详细描述了本公开所提出的负载控制装置10，然而本领域技术人员可理解的是，在不背离本公开理念的前提下，可以对上述具体实施例做出多种变型和改型，且可以对本公开提出的各种技术特征、结构进行多种组合，而不超出本公开的保护范围。
