USB HVAC检修验证
对相关申请的交叉引用 
本申请要求2010年1月27日由Alan E.Bennett等人提出的标题为“USB HVAC SERVICE VERIFICATION”的与本申请共同受让的美国申请系列号No.12/694,407的优先权，该申请的全部内容以引用的方式并入本文中。 
技术领域
本申请一般涉及加热、通风和空调(HVAC)系统，更具体而言，涉及HVAC系统的控制和配置。
背景技术
为安装、修理和维护，通常定期地或间歇性地检修HVAC系统。被检修的HVAC系统的所有者与本地HVAC服务提供商签定合同以进行这样的检修。服务提供商或其代理通过访问HVAC系统的场所来执行约定的检修。系统可以位于难以到达的位置，如建筑物屋顶。这样的位置对于将设备，特别是对于重型的和/或笨重的设备运输到HVAC系统安装地点，不是那么容易做到的。元件的暴露也阻碍诸如计算机之类的没有被加固以便在恶劣环境条件下操作的某些设备的使用。此外，在很多情况下，将诸如便携式计算机之类的贵重的电子设备托付给检修技术人员可能不被信任。
发明内容
一个方面提供包括一种用于容纳HVAC系统的组件的机壳的HVAC系统。与机壳相关联的是HVAC系统控制单元，其包括用于控制HVAC系统的操作的微控制器。HVAC系统控制单元还包括与 微控制器相关联并被配置成存储与HVAC系统的操作相关联的数据的存储器。微控制器可配置，以直接在存储器和便携式闪存设备之间传输数据。HVAC系统控制单元还包括用于直接向其耦接便携式闪存设备的便携式闪存设备接口。
另一方面提供一种制造HVAC系统的方法。该方法包括配置机壳以包含HVAC系统的组件。HVAC系统控制单元位于机壳内，并包括用于控制HVAC系统的操作的微控制器。在HVAC系统控制单元内包括了与微控制器相关联的参数存储器。该方法还包括配置参数存储器以存储与HVAC系统的操作相关联的数据。微控制器可配置，以直接在存储器和便携式闪存设备之间传输数据。给HVAC系统控制单元提供了用于将便携式闪存设备直接耦接到微控制器的便携式闪存设备接口。
再一个方面提供一种包括微控制器的HVAC系统控制单元。微控制器被配置成控制HVAC系统的操作。与微控制器相关联的存储器被配置成存储与HVAC系统的操作相关联的数据，并进一步可配置，以直接在存储器和便携式闪存设备之间传输数据。HVAC系统控制单元包括用于将便携式闪存设备直接耦接到微控制器的便携式闪存设备接口。

图8A和8B呈现制造HVAC系统的方法。
具体实施方式
诸如公司、合作伙伴、个人之类的商业HVAC系统运营商，或与HVAC服务提供商签定有关对HVAC系统进行维护的合同的任何其他实体，越来越关心由HVAC服务提供商(公司或单个检修技术人员)对HVAC系统执行的检修的质量，例如，对能量效率的影响，以及控制检修费用的愿望。根据从当前运转的HVAC系统收集的数据，确定检修的完整性，未来的检修需求，以及预期的资本改善。此外，运营商寻求确保执行的检修被有效、快速并经济合算地处理。然而，对运营商可用的数据是不完整的。
由访问HVAC单元以执行安装、修复或维护的检修技术人员提供关于HVAC单元的某些信息。然而，这样的信息通常在范围方面是有限的，而运营商无法验证报告的数据是否正确的。在某些情况下，HVAC系统是联网的，与HVAC系统的操作相关的某些数据对运营商可用。然而，在常规的HVAC操作中，这样的数据不会保证检修技术人员在物理上访问了HVAC单元。如此，运营商无法验证已经按照合同执行了未修改经由网络获取的数据的修理。
在HVAC维护的相关方面，呼叫服务中心可以为检修技术人员或HVAC系统运营商提供协助。位于呼叫中心的远程服务提供商常常置身于，在没有主体HVAC系统的详细数据的条件下去试图解决复杂问题的状态。如此，需要为远程服务提供商提供来自HVAC单元的准确而及时的数据，以提高呼叫中心支持的效率和有效性。
某些HVAC系统被配置成接受与例如膝上型计算机之类的连接。可以，例如，在制造过程中，使用这样的连接来配置HVAC系统。然而，在安装HVAC系统之后这样的连接的用途是非常有限的，因为检修技术人员常常没有便携式计算机，而安装地点，例如，户外，常常在建筑物屋顶，一般不太适合于便携式计算机。另外，当访问屋顶式HVAC系统时，例如，爬梯子，便携式计算机的重量会给检修技术人员造成困难或隐患。
Trane、Carrier、York、Aaon或其他住宅或商业HVAC制造商中没有一个已知已经认识到本文中所提供的各个实施例的优点。如此，需要验证检修、文档更改，并提供轻便的传输信息的方法。
本发明受益于这样一种独特的认识，即便携并且便宜的闪存可以有利地用于HVAC检修设置中的各种用途，以便加快检修、降低检修成本，并确保检修被执行。便携式闪存设备(PFMD)在消费电子产品中已经变得无所不在。由于非常便利并且相对来说对水和灰尘不敏感，这些设备在本文中所描述的各实施例中可作为HVAC检修技术人员进行数据传输的方便的介质。下面的描述是在屋顶式商业HVAC单元的上下文中所提供的，但是本发明不仅限于此。例如，HVAC系统120也可以是位于屋顶或地面的商用的或民用的系统。
首先参考图1，HVAC系统120a-120f的群110位于建筑物130的屋顶式上。HVAC系统120可以被配置成冷却建筑物130的内部空间。可以通过由建筑物130的拥有者或承租人操作的集中化管理系统来管理群110。例如，建筑物130可以是由连锁店运营的许多零售商店中的一个。店主可以从中心位置管理群110来监视能源消耗，并提供一般维护。
图2示出了HVAC系统120(本文有时简称为系统120)的内部方面。系统120包括用于容纳系统120的各种组件的机壳205。系统120包括压缩机210、冷凝器盘管220，以及蒸发器盘管230。在冷却建筑物130的内部空间中空气的上下文中来描述系统120的操作，但不仅限于此。压缩机210压缩流向冷凝器盘管220的制冷剂，通过冷凝器盘管220，风扇240移动空气，以将热传到周围环境。制冷剂流过膨胀阀250，冷却，并流过蒸发器盘管230。来自内部空间的被系统120调节的空气，在由吹风器260经过蒸发器盘管230移动时，被冷却。系统120的各种组件的操作至少部分地由HVAC系统控制单元270(或简称为控制单元270)进行控制。系统120是集成的HVAC系统，在机壳205内包括冷凝器盘管220和蒸发器盘管230。其他HVAC系统也在本发明的范围内，包括室内单元、室外单元、阁楼单 元，以及热泵。
图3示出了控制单元270的实施例，但不仅限于此。控制单元270可包括显示器310和输入小键盘320。显示器310可以向用户呈现各种菜单、参数，及其他配置信息。小键盘320可以接受用户输入，以在通过显示器310呈现给用户的内容中作出选择，在菜单之间浏览，以及输入配置参数。选择可以通过输入按钮325来完成。控制单元270可以有利地包括菜单图330，供用户在与控制单元270进行交互时进行参考。
控制单元270还包括便携式闪存设备(PFMD)端口340。端口340可以是硬线端口，或可包括能以无线方式与PFMD设备进行通信的无线端口。在一个实施例中，PFMD端口340被配置成将PFMD耦接到控制单元270。作为通用串行总线(USB)端口，示出了PFMD端口340，但不仅限于此。然而，本发明构想的实施例更一般而言包括任何常规或未来开发的便携式设备，包括闪存(FM)或等效物。本文中以及在权利要求书中，FM包括，但不仅限于，例如，USB闪存，也称为拇指驱动器、闪盘、笔式驱动器，及其他口语说法；以其各种修改版本以及形状因子呈现的Memory StickTM；SmartMediaTM，Compact FlashTM(CF)；Secure DigitalTM(SD)；以及如前所述的闪存类型的其他功能等效物，包括未来开发的便携式可重写固态存储器技术。下面，本发明可以参考USB FM来呈现各种实施例。这样的实施例也可不限于所使用的FM类型。
转向图4，示出了系统控制单元270的示例实施例，但不仅限于此。控制单元270包括，如前所述，小键盘320、显示器310和PFMD端口340。微控制器410接受来自小键盘320的输入，并将输出数据提供到显示器310。微控制器410可以是任何常规或未来开发的微控制器，微处理器或状态机。微控制器410响应从常规程序存储器420中读取的程序指令而操作，以控制HVAC系统120的操作的各方面。程序指令有时被称为“固件”。程序存储器420可包括用于永久性存储程序指令的非易失性存储器和临时存储数据的易失性存储器两者。 存储器也可以包括可重写存储器，例如，闪存，以允许更新程序指令。
在微控制器410的功能中，有在常规参数存储器430中存储与系统120的操作相关联的参数。参数可包括，例如，硬件配置设置、组件序列号、安装的选项、硬件修改、控制算法系数、操作数据、诊断、检修历史、温度设定值和回退(setback)时间。参数存储器430可以是易失性的或非易失性的，尽管在各实施例中，可以首选非易失性存储器，例如，闪存，以在系统120电源中断的情况下保留存储的参数。
微控制器410经由系统接口440与系统120的其他组件进行交互。系统接口440可包括寻址系统120的各种组件所需的电子组件，并提供适当的电压电平的控制信号。网络接口450可提供到例如局域网(LAN)或因特网之类的网络的接口。网络接口450可允许监视诸如操作状态，以及电能消耗之类的系统120的各个操作方面。计算机接口460提供将计算机耦接到控制单元270的装置。计算机接口460通常用于在制造过程中配置系统120。
PFM接口470将微控制器410耦接到PFMD 480。PFM接口470提供读写PFMD 480内的存储器位置所需的任何所需的信号缓存和/或地址编码/解码和/或控制信号。在某些实施例中，PFM接口470完全包含在微控制器410的功能内。在其他实施例中，PFM接口470通过分离的且不同于微控制器410的一个或多个组件来实现。
程序存储器420包括配置微控制器410以在PFMD 480和参数存储器430之间传输数据的指令。在各实施例中，这样的传输是响应于由用户经由小键盘320输入的命令进行的。在某些实施例中，微控制器410可配置，以当PFMD 480被插入到PFMD端口340中时识别PFMD 480的存在，并在参数存储器430和PFMD 480之间自动地传输数据，无需用户命令。
PFMD端口340提供供检修技术人员在PFMD 480和参数存储器430之间直接传输数据的装置。本文中以及在权利要求书中，短语“直接传输”以及其变体表示在PFMD 480和参数存储器430之间传输 数据，无需诸如便携式计算机或网络服务器之类的中间计算机的参与。在此上下文中，微控制器410不是中间计算设备。
在各实施例中，微控制器410以系统配置文件(例如，二进制或ASCII码文件)将系统配置数据存储在参数存储器430中。系统配置文件可包括与系统120的操作相关联的各个参数。在某些实施例中，系统配置文件包括几百个单个设置。具体而言，参数可以定义系统120的操作配置，该配置定义系统120的行为。这意味着，当在两个系统120上安装特定系统配置文件时，相对于HVAC组件(压缩机、风扇、吹风器等等)类似地配置的两个系统在所有操作上有意义的方面基本上以同样的方式运转。如此，例如，通过在群110中的每一个系统120上安装共同的配置文件，群110中的系统120可以被配置成以相同的方式操作。
图5示出了有利地受益于配置文件经由PFMD 480的可转移性的一般地表示为500的检修HVAC系统的方法。在步骤510中，服务提供商，例如，HVAC技术人员，将配置概况文件从第一HVAC系统120传输到PFMD 480。HVAC技术人员可以检修群集110中的一个HVAC系统120。作为检修的一部分，技术人员可以更改一个或多个参数，而这些参数又改变正在被检修的系统120的性能的某一方面。可能希望类似地修改群集110中的所有系统120，以便所有系统120都以基本上相同的特性操作。
如上文所提及的，技术人员大不可能携带便携式计算机来帮助配置群集中的其他系统120。如此，在通常情况下，技术人员通常对于群集中的每一个其他系统120重复配置过程。在HVAC系统包括类似于控制单元270的接口但是缺乏PFMD端口340的情况下，技术人员可能需要经由小键盘输入多个参数更改，需要按下几百次键。当HVAC群集包括的不仅仅是少量的HVAC系统时，输入对所有系统的更改所需的时间是很长的，并可能导致相当大的成本。
与通常的做法不同，在步骤520中，技术人员将预先从第一系统120中获取的配置文件从PFMD 480传输到第二HVAC系统120。微 控制器410被配置成直接，例如，无需另一计算机系统的协助，将配置文件从PFMD 480传输到第二HVAC系统120的参数存储器430。如果配置文件是加密的，如下面所讨论的，微控制器410也可以在将参数存储在参数存储器430之前解密其内容。控制单元270可以被配置成利用少量的击键数来执行传输，快速地重新配置第二系统120。当然，第二系统120不必位于第一系统120的附近。技术人员可以将PFMD 480放在口袋中，并在任何位置在任何时间重新配置任意数量的其他系统120。技术人员甚至可以具有多个PFMD 480，每一个PFMD都用于不同型号或配置的HVAC系统120。在某些实施例中，微控制器410存储带有时间戳或其他标识字符串的配置文件，允许技术人员从对应于系统120的所希望的配置的PFMD 480检索两个或更多配置文件中的一个。如此，可以将多个系统配置存储在单一PFMD480中，并从单一PFMD 480中检索。
最后，在步骤530中，第一和第二HVAC系统120根据存储在参数存储器430中的配置文件运转。
在各实施例中，控制单元270被配置成生成检修验证报告。检修验证报告是可以被写入到PFMD 480的数据结构。在各实施例中，数据结构包括与判断检修技术人员为系统120进行维护相关的各种数据。这样的数据的示例包括，但不仅限于，日期、时间、HVAC单元的序列号、技术人员ID、检修之前配置的配置参数，以及检修之后配置的配置参数。在各实施例中，系统控制单元270被配置为将检修验证报告从存储器(例如，参数存储器430)复制到PFMD 480。传输可以通过由技术人员经由例如小键盘320进行的击键启动。在某些实施例中，当请求将报告传输到PFMD 480时，“在运行时”生成检修验证报告。在这样的情况下，在生成检修报告时，微控制器可以从系统120中的其他位置或上下文吸收可用的数据，例如，配置文件、时间和来自系统时钟的数据等等。可以将检修验证报告提供到HVAC运营商，以在被检修的系统120中验证技术人员的存在，如下面进一步描述的。
转向图6，所示是检修验证报告600的一部分实施例。报告600根据需要可以具有许多数据字段。为便于说明，报告600包括若干个字段。字段605可包括诸如文件名之类的标识字符串。字段610可包括指出生成报告600的时间的时间戳、日期戳或类似的方式。字段615可以指出系统120被配置进行诸如，例如加热或冷却的操作的控制模式。字段620可包括操作设定值，如目标冷却温度或目标加热温度。字段625可包括备份设定值，例如，在初步控制发生故障的情况下使用的设定值。字段630可包括指出系统是否被配置成使用新鲜的或预热空气的参数。字段635可包括指出排出的空气是加热的还是冷却的参数。字段640可包括指出系统120是否被配置成有多级气流的参数。字段645可包括单元序列号。字段641、642和643可以分别包括设备操作信息，如主要部件的运行小时，设备故障的错误代码，以及自测试或安装测试的报告。而字段650可包括文件尾标志。
本文中呈现的各个实施例的特征是能够确保PFMD 480上的数据的完整性。服务提供商可能会篡改PFMD 480上的数据，如配置文件或检修验证报告，以造成检修已经执行的假像。本文中的各个实施例的目标是就HVAC运营商方面来讲经由PFMD 480所提供的支持检修要求的数据是真正的高置信度。
如此，在某些实施例中，报告600包括验证数据655。当HVAC运营商判断检修要求是否适当地反映呈现的检修时，可以使用验证数据655来验证报告600的完整性。验证数据655可包括，例如，从报告600中的其他数据字段导出的值。例如，验证数据655可包括为数据字段的真子集计算出的CRC。可将验证数据655置于报告600中的多个位置，并可以被加密。在某些情况下，相同的信息可以被置于报告600中的多个位置，对于重复的出现，使用不同的加密方案。在某些情况下，整个检修验证报告在被写入到PFMD 480时由微控制器410进行加密。
更一般而言，诸如报告600之类的检修验证报告，只是可以用来在系统120中验证服务提供商的存在的一种电子验证文件。也可以依 此方式使用系统配置文件，以及包括可以只通过在系统120上呈现由运营商轻松地获取的数据的任何电子验证文件。
在将电子验证文件传输到PFMD 480之后，服务提供商可以将PFMD 380输送到一个位置，从该位置，他或她可以以HVAC运营商可以用来在系统120上验证服务提供商的存在的形式，向HVAC运营商提供电子验证文件。例如，服务提供商可以将PFMD 380提供到HVAC运营商，可以将电子验证文件上传到可以被HVAC运营商访问的数据库或服务器，或可以将电子验证文件附到电子消息(例如，电子邮件)中。电子消息可以，例如，包括检修发票和检修验证文件。HVAC运营商可以鉴定检修验证文件，验证被请求的检修已被实际执行，并向服务提供商进行支付。
图7呈现使用电子验证文件验证检修的执行的一般表示为700的方法。参考检修验证报告600，以及系统120及其组件，描述该方法，但不仅限此。在步骤710中，服务提供商使系统120将电子验证文件传输到PFMD 480。如上文所描述的，服务提供商可以通过在系统控制单元270上选择适当的命令来进行传输。在步骤720中，服务提供商，或其代理，向HVAC运营商提供电子验证文件。HVAC运营商可以通过，例如，解密文件，计算并验证CRC值，将序列号或型号编号与设备数据库进行比较，将服务提供商序列号与服务提供商数据库进行比较等等，来处理电子验证文件。HVAC运营商也可以利用电子验证文件或通过单独的路由，接收与由服务提供商提供的检修相关联的发票。在步骤730中，HVAC运营商响应于验证接收到的电子验证文件的真实性，以及在某些情况下，验证系统验证文件所包含的参数指出实际执行过检修，来向服务提供商的帐户进行支付。
在各种实施例中，控制单元270也被配置为经由PFMD端口340提供额外的有用功能。在一个实施例中，控制单元270被配置成利用位于PFMD 480上的已更新的程序指令更新位于程序存储器420上的程序指令。更新可以响应于经由小键盘320输入的命令，或当微控制器410识别出PFMD 480上的已更新的固件时自动地进行。
在一个实施例中，控制单元270被配置成在PFMD 480上存储控制器状态日志和错误日志。这些数据，例如，可以用于由HVAC运营商、制造商或经销商以后进行分析。可以将这样的数据上传到检修数据库，或以其他方式传输到有关的当事人。在某些情况下，将系统120操作数据传输到PFMD 480，并传输到诸如中心制造商服务中心或“帮助台”之类的远程服务提供商。远程代理，无论是人或机器，可以使用操作数据来诊断系统误差、故障等等。预计由远程代理拥有这些数据，以简化远程代理进行的诊断，并缩短从远程代理获取建议、对错误的诊断，或其他信息所需的时间，并降低成本。在某些情况下，将数据传输给分析师，以确定系统120的操作趋势。例如，操作参数可以揭示与预防性维护或能源消耗的减少相关的趋势。
控制单元270也可以被配置成经由PFMD端口340支持各种实用功能。例如，当被配置为USB端口时，PFMD端口可以给灯或风扇提供电源，或者，可以对诸如蜂窝电话之类的便携式电子设备进行充电。
控制单元270也可以被配置成经由PFMD端口340提供某些诊断能力。例如，控制单元270可以向耦接到PFMD端口340的计算机提供诸如序列号、配置数据、固件修改、冷却液压力和错误代码之类的系统数据。在某些实施例中，控制单元270被配置成通过PFMD端口340向它分配电源，以给执行如前所述的数据的传输所需的传感器或其他电子器件通电。这样的实施例在制造或装运上下文中可以具有特定用途，以提供确定系统120的标识或基本状况的手段，无需去除包装材料，打开面板等等。
现在转向图8A，呈现了制造HVAC系统的一般表示为800的方法。参考系统120以及其组件，描述了该方法，但不仅限此。在步骤810中，诸如机壳205之类的外壳被配置成包含HVAC系统120的组件。在步骤820中，将诸如控制单元270之类的HVAC系统控制单元定位于外壳内。接口包括用于控制HVAC系统的操作的微控制器。在步骤830中，将存储器包括在HVAC系统控制单元内，并使其与 微控制器相关联。在步骤840中，存储器被配置成存储与HVAC系统的操作相关联的数据。在步骤850中，给HVAC系统提供了用于将PFMD直接耦接到微控制器的便携式闪存设备接口。
图8B呈现了方法800中的额外的可选步骤。在步骤860中，HVAC系统控制单元被配置成从便携式存储器设备下载固件更新。固件更新可以由微控制器410安装在程序存储器420中，例如。在步骤870中，HVAC系统控制单元被配置成从便携式闪存设备下载预先存储的配置文件。在步骤880中，HVAC系统控制单元被配置成使HVAC系统根据预先存储的配置文件来进行操作。在步骤890中，HVAC系统控制单元被配置成以加密形式将数据存储在PFMD中。
对于本申请所涉及的内容，本领域技术人员将理解，可以对所描述的实施例进行其他和进一步的添加、删除、替换和修改。
