Description

具有双级故障保险电路的无线恒温器
技术领域
本申请关于恒温器。更特别地，本申请关于具有多级备份电路以提供故障保险操作的无线恒温器。
背景技术
电子恒温器具有许多特征，包括节能操作和用于远程访问的无线通信。通常这些电子恒温器使用24VAC或电池供电来操作。
具有无线RF通信的恒温器可以汲取相当多的电力，并且当失去电力时，温度控制的主要功能出故障。在冬季月份期间，住宅没有暖气持续延长的时段可以导致水管冻结并且最终导致花费昂贵的维修和贵重物品的损失的破裂。
对于具有可再充电的电池备份的24VAC供电类型的恒温器，在失去AC的某时段之后，仍存在电池耗尽的可能性。不存在故障保险机制来保持燃气加热（gasheat）运行。如果房主忘记用新的电池组定期地替换当前的电池，则针对电池供电而言，可以发生相同的问题，并且，不存在故障保险机制来将房屋温度保持在正常的界限之内。
发明内容
根据本发明的第一方面，提供了一种恒温器，其包括无线发射机；耦合到所述发射机的控制电路；电力感测电路；耦合到控制电路的热传感器，其中控制电路对预设的温度要求进行响应以激活所选择的输出；其中，响应于在第一级别处感测可用的电力，无线通信被减少到预定的级别，并且响应于在较低的第二级别处感测可用的电力，通过热响应开关激活选择的输出。
附图说明
图1是根据本文的恒温器的框图。
具体实施方式
尽管公开的实施例可以采取许多不同的形式，但是本申请具体实施例被示出在图中，并且将在本文中被详细描述，其中应理解，本公开将被视为本申请原理的范例以及实行该原理的最佳模式，并且不意图将本申请权利要求书限制为所说明的具体实施例。
在本申请实施例中，被内置于电子RF通信恒温器的多个低成本的故障保险机制提供了多于一个级别的备份。当检测到低电力条件时，第一级别备份电路减少RF通信。例如，24VAC输入电压的故障，或者在电池备份电压电平中检测到的低于安全操作级别的下降。
恒温器将仅使用最小电力来维持温度控制并且切断RF通信以每天仅将低电力状态发出一次。其将不发送任何其他通信消息，其也将不接收任何传入的消息。
可以以诸如Wi-Fi、Z-Wave或ZigBee、单向或双方向RF通信之类的任何形式的射频通信或技术来实现RF通信。
第二级别的备份电路包括机械双金属热控开关，用于在完全失去电力的情况下提供最小的加热操作。这对于没有电池备份的24VAC供电的恒温器特别有用。紧接在失去AC之后，该类型的恒温器将失去温度控制。
当该恒温器电子设备在其电力完全用光之后关闭时，机械双金属热控开关将接管以提供基本的加热控制并且将在房屋或被监视的区域中的热度维持在冻结级别之上。双金属热控开关不需要任何电力来提供在预设的温度设置处的打开和闭合电路的功能。这提供了双级故障保险设计以延伸恒温器的操作，并且以来自安装的区域加热系统或应急燃气加热系统的燃气热保护住宅。而且，其使得在恒温器中的电子故障的风险最小化。
图1图示了恒温器10的框图，所述恒温器10包括多模式备份电路并且其是本申请示例性实施例。恒温器10包括携带控制电路14的外壳12。可以至少部分地通过已编程的处理器14a以及相关联的可执行指令14b实现电路14。一个或多个加热/冷却控制开关14c还耦合到控制电路14，如后续讨论的那样。
外壳12还携带用户显示器16a以及人工可操作的温度设置元件16b。外壳12还携带区域温度传感器20，以及AC和/或DC电源，或电压传感器22。
控制电路还耦合到无线收发机24和天线24a。将理解，无线传输的确切类型和解调的类型都不是本申请的限制。
基于来自温度传感器20的信号，经由控制开关14c以及可以经由电缆C耦合到局部区域加热/冷却系统HVAC的输出端口30，控制电路14执行区域温度调节功能。这样的耦合将为本领域技术人员周知，并且无需进一步讨论。
响应于来自传感器22的电力水平感测信号，控制电路14还可以响应于可用的电力下降到第一预定阈值以下而执行初始备份操作。响应于归因于电气故障或者归因于在局部电池32处的电压下降的检测到的电力下降，控制电路14的能量使用功能可以被暂时减少或消除。例如，代替诸如每小时的在周期性基础上经由收发机24例行地传输状态信号或者其他消息，可以在传输之间以诸如每天的长得多的间隔暂时地传输这样的消息以节能。
在上文描述的初始备份模式中时，控制电路14可以经由开关14c以其通常的方式继续控制HVAC系统，以将区域温度维持在区域R中的用户的温度设置处。
双金属温度控制开关28也由外壳12携带以提供第二备份操作模式。响应于重大的电力损失，例如在电池32的输出电压中的、基本上到零伏特的下降，双金属开关28运转以激活HVAC系统来向区域R提供较低的备份级别的加热，而无需来自本地电源32的电能。
总之，本申请的实施例可以被开发成连接的恒温器，其通过WiFi或Z-Wave传输通信并且其是24VAC或电池供电。诸如电路14的电子控制电路可以检测低电力模式，例如如果电池32的电压下降的话。响应于检测到的下降，除了基本的低电池状态报告以外，RF通信可以被关闭，或者被相当大地减少，以保存电力。电路14可以继续控制HVAC系统来维持在区域R中预设的温度。
如果总电力失去并且电子控制电路14不能将室温维持在其常规设置点处，则第二备份系统变得可操作（operational）。例如，当室温下降到阈值设定点40F之下时，内部的机械双金属热控开关28将通过其热控开关的基于温度地打开和闭合来接管操作加热系统。
根据上述将观察到，可以实现许多变型和修改，而没有背离本发明的精神和范围。应理解，不意图或不应推断关于本文说明的具体装置的限制。当然，意图通过所附权利要求书来覆盖落入权利要求书的范围之内的所有这样的修改。
