技术领域
本公开涉及空调技术领域，具体而言，涉及一种新风系统控制方法、装置及空调机组。
背景技术
新风机一般分为内循环和外循环两种模式，这两种模式通过进风口处和出风口处两个风阀的开关来转换。其中风阀存在完全没打开或处于半开状态的情况，然而风阀开关是否到位会严重影响新风机的性能。
市场上现有的风阀是否开关到位的检测方式，大部分采用机械方式检测风阀是否到位。例如风阀撞击开关，这种方式精度差且寿命短。现有技术中还采用光电检测的方式检测风阀是否到位，这种方式能够提高检测装置的寿命，但是为了更加精准地检测到风阀的位置，一般会在风阀的开启位置和关闭位置都装有关电开关，即一个风阀需要采用双光电开关，即两个光电开关。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
发明人发现：相关技术中新风系统中为了精准检测风阀开关到位情况，需要采用双光电开关，造成了资源浪费。本公开提供了一种新风系统控制方法、装置及空调机 组，以至少解决现有技术中新风系统中为了精准检测风阀开关到位情况需要采用双光电开关，造成资源浪费的问题。
本公开提供了一种新风系统控制方法，该控制方法例如直接应用至各种新风系统上，或者应用至具有新风系统功能的空调系统上，具体实现时，例如，通过在新风系统安装软件、APP、或者写入控制器相应的程序的方式来实现。
通常新风系统的新风进风口及排风出风口侧为室外侧，新风出风口及排风进风口侧为室内侧。新风进风处装有新风阀，排风出风处装有回风阀。当新风阀和回风阀都打开时，运行外循环模式，如图1中示出的。当两个风阀都关闭时，运行内循环模式，如图2中示出的。
新风阀或者回风阀的结构如图3所示，在风阀转轴上有两个挡片，根据位置的不同分为开到位挡片2及关到位挡片3。风阀上安装有光电开关1，新风阀装设有第一光电开关，回风阀装设有第二光电开关，位置关系如图3所示(图中位置为关闭状态)。转轴由步进电机带动转动，同时会带动挡片的位置改变(由关闭到打开转轴会转动90度)，同时也会造成光电开关信号的改变，挡片挡住光电开关时，光电开关反馈电路会反馈回低电平，没有挡住时会反馈回高电平。
新风阀和回风阀的位置状态极为重要，但是风阀有很大可能由于某种原因(如风道存在异物)导致无法精准到达全开位置或者关位置。图4中示出光电开关与风阀挡片位置一种可选的示意图，在图4中风阀为关闭状态；图5中也示出光电开关与风阀挡片位置一种可选的示意图，在图5中风阀为半开状态；图6中示出光电开关与风阀挡片位置另一种可选的示意图，在图6中风阀为全开状态。
基于上述新风系统，本公开提供了一种新风系统控制方法，具体来说，图7示出该方法的一些实施例的流程图，如图7所示，该方法包括如下步骤S702-S706。
在步骤S702中，获取风阀的开关状态。
在步骤S704中，检测光电开关的电压信号；其中，电压信号至少包括电平变化次数和最终电平状态。
在步骤S706中，根据电压信号判断风阀是否开关到位，并根据判断结果控制新风系统的运行。
在上述实施方式中，提供了一种新风系统控制方案，在该新风系统的风阀设有一个光电开关，检测光电开关的电压信号，根据电压信号判断风阀是否开关到位。该方案通过单光电开关就可较为精确检测风阀部件开关是否到位，既解决了机械式开关寿 命短的问题，又解决了多光电开关资源浪费的问题，能够简单、精准地确定风阀部件开关是否到位，并且节约了成本。
如图1中示出的，风阀至少包括新风阀和回风阀，光电开关至少包括设置于新风阀的第一光电开关和设置于回风阀的第二光电开关。当新风阀和回风阀都打开时，运行外循环模式。如图2中示出的，当两个风阀都关闭时，运行内循环模式。在运行模式为外循环模式时，新风阀和回风阀的开关状态均为开启状态。在运行模式为内循环模式时，新风阀和回风阀的开关状态均为关闭状态。
通过上述分析能够确定，新风阀和回风阀的开关状态由新风系统的运行模式确定。因此，获取风阀的开关状态，包括：确定新风系统的运行模式；根据运行模式确定风阀的开关状态。
机组上电之后先对新风进风处装的新风阀和排风出风处装的回风阀，复位到关的位置(复位过程不检测是否能够到位)。即在确定新风系统的运行模式之前，还包括：控制新风阀和回风阀复位至关闭状态。之后，如果用户操作系统开机，系统会先运行一段时间(例如5min)的外循环模式(即新风阀和回风阀都打开，目的为引进室外空气用以判断之后需要运行何种模式)。因此，确定新风系统的运行模式，包括：检测新风系统的运行状态；其中，运行状态至少包括开机状态；根据运行状态确定新风系统的运行模式；其中，在运行状态为开机状态时，运行模式为外循环模式。
光电开关的反馈信号变化大致分为以下几种：低高低(关位置→半开位置→全开位置)、高低(半开位置→全开位置)、高(一直卡在半开位置)、低(一直卡在关位置或者全开位置)、低高(关位置→半开位置)；风阀执行关闭动作时有以下：低高低(全开位置→半开位置→关位置)、高低(半开位置→关位置)、高(一直卡在半开位置)、低(一直卡在关位置或者全开位置)、低高(全开位置→半开位置)。综合以上几种风阀的动作位置得出以下结论：不管开阀还是关阀，只有反馈信号为低高低或者高低时为风阀动作到位。因此，当风阀复位(复位时两个风阀会关闭)后，风阀开始动作时检测风阀到位情况，电平每变化一次就记一次数，当风阀整个过程动作完毕之后，判断电平变化记录的次数与风阀最终状态时光电开关的电平状态。如果判断到电平变化次数大于等于一次且风阀动作完成之后光电开关最终电平状态为低电平时，认为风阀已经开到位或者关到位，否则判断为风阀开关故障。
具体地，检测光电开关的电压信号，包括：检测第一光电开关和第二光电开关的电平变化次数和最终电平状态。根据光电开关的电压信号判断新风阀和回风阀是否开 关到位，包括：如果电平变化次数大于等于一次且最终电平状态均为低电平，则确定风阀开关到位，否则，确定风阀开关故障。具体地，如果第一光电开关的电平变化次数大于等于一次且最终电平状态均为低电平，则确定新风阀开关到位，否则，确定新风阀开关故障；如果第二光电开关的电平变化次数大于等于一次且最终电平状态均为低电平，则确定回风阀开关到位，否则，确定回风阀开关故障。
在一些实施例中，判断结果至少包括以下之一：开关到位、开关故障；根据判断结果控制新风系统的运行，包括：在新风阀和回风阀开关到位时，获取新风系统所在室内的环境参数，该环境参数主要包括温度和湿度，根据环境参数确定新风系统的运行模式，并根据运行模式控制新风阀和回风阀的开关状态，其中，运行模式至少还包括内循环模式；在新风阀和回风阀开关故障时，控制新风系统进入待机模式或关机模式。当然，例如，如果检测到用户未执行关机操作，直接进入内循环模式。
在运行模式为内循环模式，并根据运行模式控制新风阀和回风阀的开关状态之后，还包括：检测第一光电开关和第二光电开关的电压信号；根据第一光电开关和第二光电开关的电压信号判断新风阀和回风阀是否开关到位。此过程主要用于检测新风阀和回风阀是否达到关闭位置，通过上述分析能够确定，新风阀和回风阀是否达到关闭位置或达到开启位置的检测原理一致，因此运行模式为内循环模式时，检测第一光电开关和第二光电开关的电压信号，根据第一光电开关和第二光电开关的电压信号判断新风阀和回风阀是否开关到位的实现方案，与运行模式为外循环模式时一致。
本公开还提供了另一种新风系统控制方法，具体来说，图8示出该方法的一些实施例的流程图，如图8所示，该方法包括如下步骤S801-S814。
在步骤S801中，开始。
在步骤S802中，上电。
在步骤S803中，风阀复位到关位置；机组上电之后先对新风进风处装的新风阀和排风出风处装的回风阀复位到关的位置(复位过程不检测是否到位)。
在步骤S804中，开机，机组固定先运行5分钟外循环。如果用户操作机组开机，机组会先运行5min的外循环模式(即新风阀和回风阀都打开，目的为引进室外空气用以判断之后需要运行何种模式)。
在步骤S805中，风阀开到位检测。此时需要判断两个风阀是否开到位，风阀的位置会以图4→图5→图6(此情况为上电复位后风阀能够到关位置)或者图5→图6(此情况为上电复位后风阀只能够到半开位置)运行。
在步骤S806中，光电开关反馈信号变化时计数。这个过程就会使光电开关接收到低高低或者高低的电平信号，只要电平一发生变化就计一次数。
在步骤S807中，确定计数值>＝1且停止时为低电平；如果是，则进入步骤S809，否则，进入步骤S808；等到动作完成之后判断计数值以及光电开关最终的电平值，如果计数值大于等于一次且光电开关最终电平状态为低电平时认为风阀打开到位，否者判定为开不到位。
在步骤S808中，故障，判定为风阀开不到位，则说明风阀开关故障，之后进入S811。
在步骤S809中，根据外循环参数正常运行；运行5分钟外循环之后根据引进的环境参数(温度、湿度等)自动判断运行内循环还是外循环，如果为外循环则无需动作继续运行，如果为内循环则需要关闭两个风阀。
在步骤S810中：手动关机，在正常运行中判断用户是否关机，如果是，则进入步骤S811，否则，进入步骤S812；
在步骤S811中，关机/待机；之后，返回步骤S814；
在步骤S812中，运行内循环；判断是否运行内循环模式，如果是，则进入步骤S813，否则，进入步骤S809；
在步骤S813中，风阀关到位检测；之后，返回步骤S807；运行内循环模式，需要判断是否关到位，关闭动作以图6→图5→图4(此情况为运行外循环模式开阀之后阀一直处于全开位置)或者图5→图4(此情况为运行外循环模式开阀之后阀被外力打到半开位置)运行，这个过程就会使光电开关接收到低高低或者高低的电平信号，只要电平一发生变化就计一次数，等到动作完成之后判断计数值以及光电开关最终的电平值，如果计数值大于等于一次且光电开关最终电平状态为低电平时认为风阀关到位，否者判定为关不到位转为待机或关机状态；
在步骤S814中，结束。
