Description
本发明涉及空调控制技术领域,具体涉及一种室外机唤醒方法、装置以及多联机空调系统。
多联机空调系统通常包括一个室外机和多个室内机,室外机通过控制压缩机的冷媒循环量以及进入到每个室内机中室内换热器的冷媒流量来满足每个室内机所处环境内冷热负荷的需求。当所有室内机均处于关机状态时,为了保证任意一个室内机启动后室外机都能够控制压缩机运转满足室内机的运行需求,需要控制室外机处于待机状态。目前常规的室外机待机方法主要是控制压缩机断电以降低室外机能耗,但仍需要使室外机的外机控制器保持与每个室内机正常通讯的状态,当外机控制器接收到某个室内机发送的启动指令时会根据该指令唤醒压缩机(室外机由待机状态转换为正常运行状态)。由于外机控制器一直处于正常通讯状态,因此仍会消耗电能,无法进一步降低室外机能耗。如果同时控制压缩机和外机控制器断电,使室外机处于零功耗待机状态,外机控制器将无法接收室内机发送的启动指令,唤醒压缩机,从而导致室内机无法正常运行。

在实施本发明的技术方案中,可以通过室内机的内机控制器实施根据本发明实施例的室外机唤醒方法,该方法可以在室外机处于零功耗待机状态时,响应于接收到的内机开机指令,对内外机通讯总线施加预设电压幅值的直流电,以使室外机上预先设置的供电模块将直流电输出至外机控制器进行供电,唤醒外机控制器,进而唤醒整个室外机。其中,供电模块可以在内外机通讯总线的总线电压大于等于预设电压阈值时使内外机通讯总线与外机控制器连通,预设电压幅值大于等于预设电压阈值。此外,在实施本发明的技术方案中,零功耗待机状态指的是室外机的外机控制器和压缩机等核心电子器件均处于关机的状态,在该状态下室外机消耗的电功率是零,也就是说,根据本发明实施例的室外机唤醒方法能够在室外机处于零功耗待机状态下通过室内机唤醒室外机。
下面参照附图来描述本发明的具体实施方式,附图中:
图1是根据本发明的一个实施例的室外机唤醒方法的主要步骤流程示意图;
图2是根据本发明的一个实施例的对内外机通讯总线施加直流电的主要步骤流程示意图。
下面参照附图来描述本发明的一些实施方式。本领域技术人员应当理解的是,这些实施方式仅仅用于解释本发明的技术原理,并非旨在限制本发明的保护范围。
在本发明的描述中,“模块”、“处理器”可以包括硬件、软件或者两者的组合。一个模块可以包括硬件电路,各种合适的感应器,通信端口,存储器,也可以包括软件部分,比如程序代码,也可以是软件和硬件的组合。处理器可以是中央处理器、微处理器、图像处理器、数字信号处理器或者其他任何合适的处理器。处理器具有数据和/或信号处理功能。处理器可以以软件方式实现、硬件方式实现或者二者结合方式实现。非暂时性的计算机可读存储介质包括任何合适的可存储程序代码的介质,比如磁碟、硬盘、光碟、闪存、只读存储器、随机存取存储器等等。术语“A和/或B”表示所有可能的A与B的组合,比如只是A、只是B或者A和B。术语“至少一个A或B”或者“A和B中的至少一个”含义与“A和/或B”类似,可以包括只是A、只是B或者A和B。单数形式的术语“一个”、“这个”也可以包含复数形式。
参阅附图1,图1是根据本发明的一个实施例的室外机唤醒方法的主要步骤流程示意图。根据本发明实施例的室外机唤醒方法可以应用于室内机的内机控制器,例如可以通过内机控制器加载并运行执行室外机唤醒方法的计算机程序代码。如图1所示,本发明实施例中的室外机唤醒方法主要包括下列步骤S101-步骤S103。
在步骤S101中,在室外机处于零功耗待机状态时,室内机判断是否接收到内机开机指令。若接收到内机开机指令,则转至步骤S102;若没有接收到内机开机指令,则转至步骤S103。
本实施例中的零功耗待机状态指的是室外机的外机控制器和压缩机等核心电子器件均处于关机的状态,在该状态下室外机消耗的电功率是零。此外,本领域技术人员能够理解的是,当室外机待机时室内机必然也处于待机状态/关机状态。
内机开机指令指的是控制室内机开机运行的指令。在本实施例中,当室外机处于零功耗待机状态时室内机接收到内机开机指令后可以唤醒室外机,使室外机由零功耗待机状态转换为开机运行状态,以保证室外机能够正常地控制压缩机运行,满足室内机的运行需求。
在步骤S102中,对内外机通讯总线施加预设电压幅值的直流电,以使室外机内预置的供电模块能够将所述直流电输出至外机控制器进行供电,唤醒外机控制器,进而唤醒整个室外机。当外机控制器被唤醒后,其可以控制室外机内的压缩机等其他核心器件启动,完成整个室外机的唤醒工作。需要说明的是,外机控制器控制压缩机等其他核心器件启动,完成整个室外机的唤醒工作的具体操作过程,是空调技术领域中的常规手段,在此不再赘述。
内外机通讯总线指的是能够传输室内机与室外机之间的通讯信号的总线。本发明实施例中的空调系统可以基于室内机与室外机之间的通讯方式,采用通讯技术领域中常规类型的通讯总线构建室内机与室外机之间的内外机通讯总线。通讯总线的总线类型包括但不限于:RS-485总线、CAN(Controller Area Network)总线和Homebus等。为了描述简洁,在此不再对上述通讯总线进行赘述。
预设电压幅值的直流电指的是电压幅值是预设数值的直流电。例如:预设电压幅值是5V的直流电表示该直流电的电压幅值是5V。
室外机内预置的供电模块分别与室外机的内外机通讯总线以及外机控制器连接,该供电模块能够在内外机通讯总线的总线电压大于等于预设电压阈值时使内外机通讯总线与外机控制器连通,换言之,供电模块能够使内外机通讯总线与外机控制器形成一个导通回路。在本实施例中可以设定施加在内外机通讯总线上的直流电的电压幅值(预设电压幅值)大于等于上述预设电压阈值,因此当对内外机通讯总线施加预设电压幅值的直流电后,供电模块可以使内外机通讯总线与外机控制器连通,进而使内外机通讯总线上传输的预设电压幅值的直流电输出至外机控制器,向外机控制器供电,外机控制器得电后即可被唤醒。
在本发明实施例的一个实施方式中,室外机内预置的供电模块可以包括整流电路和电压比较电路。在本实施方式中,整流电路的输入端与内外机通讯总线连接,整流电路的输出端与电压比较电路的输入端连接;电压比较电路的输出端与外机控制器的供电回路连接;供电回路包括继电器和开关电源。下面分别对整流电路和电压比较电路进行具体说明。
1、整流电路
在本实施例中整流电路可以被配置成对内外机通讯总线的总线电压进行电压极性转换。当采用无极性的内外机通讯总线时,由于总线线路之间没有正负极性之分,因此内外机通讯总线输出的直流电的电压极性是不确定的,通过设置整流电路就可以将电压极性不确定的直流电,转换成电压极性确定的直流电,保证电压比较电路的正常工作。
需要说明的是,在本实施例中可以采用整流技术领域中常规的整流拓扑构建整流电路。常规的整流拓扑包括但不限于:全桥整流结构等。为了描述简洁,在此不再对上述整流拓扑结构的具体结构进行赘述。
2、电压比较电路
在本实施例中电压比较电路可以被配置成判断经电压极性转换后的总线电压的电压幅值是否大于等于预设电压阈值并且在所述电压幅值大于等于预设电压阈值时将内外机通讯总线上传输的电能输出至供电回路中的继电器,以导通继电器并使内外机通讯总线上传输的电能经过这个导通的继电器输出至供电回路的开关电源进行充电,进而使开关电源在充电启动后向外机控制器供电。
供电回路中的继电器可以是常开型继电器,该继电器的供电电路(包括继电器的供电线圈)得电后即可自动导通(如控制继电器的开/合机构自动闭合)。
供电回路中的开关电源可以采用电源技术领域中常规的开关模式电源SMPS(Switching Mode Power Supply),此外,本实施例中的开关电源可以采用电源技术领域中常规的充电软启动的方式控制开关电源启动,在开关电源未启动时通过向其充电,使得充电电压达到开关电源的启动电压,开关电源就可以启动。为了描述简洁,在此不再对充电软启动的电路结构和/或方法进行赘述。
本实施例中在利用内外机通讯总线上传输的电能启动开关电源,进而唤醒外机控制器后,外机控制器启动后可以控制开关电源与室外机的外部电源连通,使用外部电源继续为外机控制器以及整个室外机供电,即内外机通讯总线上传输的电能用于室外机唤醒,而非是向室外机持续供电,保证室外机启动后的正常运行。
需要说明的是,虽然本发明实施例仅提供了上述一种具体的供电模块的实施方式,但是,本领域技术人员能够理解的是,本发明的 保护范围并不局限于这一具体实施方式,本领域技术人员可以采用其他的模块结构设置供电模块,只要其能够在内外机通讯总线的总线电压大于等于预设电压阈值时使内外机通讯总线与外机控制器连通,将内外机通讯总线上传输的电能输出至外机控制器的供电回路,向外机控制器供电,唤醒外机控制器。在不偏离本发明的原理的前提下,本领域技术人员可以对相关技术特征做出等同的更改或替换,这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
步骤S103:不进行唤醒操作。
当室内机没有接收到内机开机指令,表明没有使用空调的需求,因此也就无需唤醒室外机。
进一步,在根据本发明实施例的一个实施方式中,可以将根据本发明实施例的室外机唤醒方法应用于多联机空调系统,由于多联机空调系统包括多个室内机,因此可能存在至少两个室内机都接收到内机开机指令的情况,对此可以使每个室内机向内外机通讯总线施加直流电之前,先判断一下是否有其他室内机正在唤醒室外机或者室外机已经被其他室内机唤醒,如果确认室外机未被唤醒,再向内外机通讯总线施加直流电。具体而言,参阅附图2,在本实施方式中,室内机在接收到内机开机指令后可以按照下列步骤S201-步骤S206选择性地向内外机通讯总线施加预设电压幅值的直流电。
步骤S201:检测内外机通讯总线的总线电压。
步骤S202:判断总线电压是否大于等于预设电压阈值;若总线电压大于等于预设电压阈值,则转至步骤S203;若总线电压小于预设电压阈值,则转至步骤S204。
步骤S203:若总线电压大于等于预设电压阈值,则表明可能有其他室内机正在向内外机通讯总线施加预设电压幅值的直流电,进行室外机唤醒操作。因此,在检测到总线电压是否大于等于预设电压阈值时,可以延迟预设时间后判断当前室内机与室外机是否能够相互通讯;如果能够相互通讯,则表明确实是有其他室内机执行室外机唤醒操作并且室外机已经被成功唤醒,此时无需再向内外机通讯总线施加直流电,进行室外机唤醒操作(转至步骤S206)。如果不能够相互通讯,则表明可能是有其他室内机执行室外机唤醒操作,但是室外机唤醒失败,此时仍需要向内外机通讯总线施加直流电,进行室外机唤醒操作(转至步骤 S204)。需要说明的是,在本实施方式中可以采用空调通讯技术领域中常规的通讯检测方法判断当前室内机与室外机是否能够相互通讯。例如:室内机向室外机发送通讯请求信号,若接收到室外机根据通讯请求信号反馈的应答信号,则表明室内机与室外机能够相互通讯。为了描述简洁,在此不再对上述通讯检测方法进行赘述。
步骤S204:施加直流电,即向内机通讯总线施加预设电压幅值的直流电,该步骤的具体操作过程与前述步骤S102中所述的施加直流电的具体操作过程相同,为了描述简洁,在此不再赘述。
在本实施方式中,为了保证室外机被唤醒后,室内机与室外机可以通过内外机通讯总线正常地传输通讯信号,需要防止施加在内外机通讯总线上的直流电干扰通讯信号,因此可以对内外机通讯总线持续施加直流电并且在持续施加时间达到预设时长后停止施加直流电,即在预设时长后若室外机已经被成功唤醒,此时内外机通讯总线也没有上述直流电的干扰,室内机与室外机可以通过内外机通讯总线正常通讯。
步骤S205:判断室内机与室外机是否能够相互通讯;若能够相互通讯,则表明在施加完直流电后已经成功唤醒室外机,此时可以转至步骤S206,停止执行唤醒操作。若不能相互通讯,则表明在施加完直流电后没有成功唤醒室外机,此时可以转至步骤S201,重新执行步骤S201,进而根据步骤S201的结果选择性地执行后续步骤,直至室外机被唤醒,当前室内机能够与室外机相互通讯。
步骤S206:停止唤醒操作,即停止执行关于唤醒室外机的相关操作。
需要指出的是,尽管上述实施例中将各个步骤按照特定的先后顺序进行了描述,但是本领域技术人员可以理解,为了实现本发明的效果,不同的步骤之间并非必须按照这样的顺序执行,其可以同时(并行)执行或以其他顺序执行,这些变化都在本发明的保护范围之内。
进一步,本发明还提供了一种室外机唤醒装置,其设置于室内机的内机控制器,此外室外机上设置有分别与内外机通讯总线以及外机控制器连接的供电模块,供电模块可以配置成在内外机通讯总线的总线电压大于等于预设电压阈值时使内外机通讯总线与外机控制器连通。在本实施方式中,室外机唤醒装置可以被配置成在室外机处于零功耗待机状态时,响应于接收到的内机开机指令,对内外机通讯总线施加预设 电压幅值的直流电,以使供电模块能够将直流电输出至外机控制器进行供电,唤醒外机控制器;其中,预设电压幅值大于等于预设电压阈值。一个实施方式中,具体实现功能的描述可以参见步骤S101-步骤S103所述。
在一个实施方式中,室外机唤醒装置可以包括直流电施加模块。在本实施方式中直流电施加模块可以被配置成执行下列操作:步骤S1:检测内外机通讯总线的总线电压是否大于等于预设电压阈值;若是,则转至步骤S2;若否,则转至步骤S3。步骤S2:在延迟预设时间后判断室内机与室外机是否能够相互通讯;若是,则不施加直流电;若否,则转至步骤S3。步骤S3:施加直流电。一个实施方式中,具体实现功能的描述可以参见步骤S201-步骤S206所述。
进一步,在本实施方式中直流电施加模块可以被进一步配置成在停止施加直流电之后,判断室内机与室外机是否能够相互通讯;若否,则转至步骤S1。一个实施方式中,具体实现功能的描述可以参见步骤S201-步骤S206所述。
进一步,在本实施方式中直流电施加模块可以被进一步配置成在对内外机通讯总线持续施加直流电并且在持续施加时间达到预设时长后停止施加直流电。一个实施方式中,具体实现功能的描述可以参见步骤S201-步骤S206所述。
在一个实施方式中,供电模块可以包括整流电路和电压比较电路。在本实施方式中,整流电路的输入端与内外机通讯总线连接,整流电路的输出端与电压比较电路的输入端连接;电压比较电路的输出端与外机控制器的供电回路连接;供电回路可以包括继电器和开关电源。整流电路可以被配置成对总线电压进行电压极性转换;电压比较电路可以被配置成判断经电压极性转换后的总线电压的电压幅值是否大于等于预设电压阈值并且在电压幅值大于等于预设电压阈值时将内外机通讯总线上传输的电能输出至继电器,以导通继电器并使电能经继电器输出至开关电源进行充电,进而使开关电源在充电启动后向外机控制器供电。一个实施方式中,具体实现功能的描述可以参见步骤S102所述。
