Description

多联式控制系统的地址竞争方法 技术领域
本发明属于空调技术领域，具体涉及一种多联式控制系统的地址竞争方法。
背景技术
多联式系统是指一台室外机通过配管连接两台或者两台以上的室内机，在室外侧采用风冷换热的形式，在室内侧采用蒸发换热的形式一次性制冷剂的空调系统。随着科技的发展，多联式系统广泛地应用于大型的商场、楼宇群中，人们对于多联式系统控制的区域要求越来越高。
多联式系统的室外主机可以对室内机进行独立的控制和调节，满足不同室内机对不同负荷的需求。每个室外主机可以连接多个室内机，室内机可以分布于不同的房间，甚至是不同的建筑楼，因此也就需要室外主机与室内机进行远距离通信。但是远距离通信存在信号衰减、信号干扰等问题。目前，为了延长室外主机和室内机的通信距离，往往采用高性能的通信芯片，或者增加中继设备器实现一对一通信。
采用高性能的通信芯片虽然能够在一定程度上增加通信距离，但是延长的通信距离有限，并且多联机系统中的室外主机和室内机要同时更换芯片，需要付出昂贵的成本代价；现在的通信中继器通常采用数据透传的方式，只能实现一对一通信，通过增加中继设备器的数量延长通信距离的方式，增加的中继设备的数量越多，安装的成本也就越高。
通过多个中继设备连接多个室内机后如何保证各个室内机地址唯一且不冲突是本领域技术人员目前需要解决的问题，现有技术大部分采用人为设定室内机地址的方式来解决上述问题，但是这样安装麻烦，且效率较低。
因此，如何提出一种提高空调室内机地址配置效率低下的方案是本领域技术人员目前需要解决的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围
下面参照附图来描述本发明的优选实施方式。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。
参阅附图1，图1示例性的给出了本发明一种实施例的多联式控制系统的地址竞争方法的主要步骤，其中，多联式控制系统主要包括主控制设备、中继设备和多个从控制设备，从控制设备中的一部分与主控制设备直接通信连接，从控制设备中的另一部分通过中继设备与主控制设备通信连接。如图1所示，本发明实施例中多联式控制系统的地址竞争方法包括下述步骤：
步骤S101：中继设备根据第一从控制设备发起地址请求的顺序依次为每个第一从控制设备分配临时地址。
参阅附图2，图2示例性的给出了本发明一种实施例的多联式控制系统的主要结构。在本发明实施例中，多联式控制系统可以包括主控制设备、中继设备和多个从控制设备，从控制设备可以包括第一从控制设备和第二从控制设备，中继设备可以直接与第一从控制设备通信连接，也可以通过连接其他的中继设备与第一从控制设备连接。第一从控制设备可以是通过中继设备与主控制设备连接的从控制设备，第二从控制设备可以是直接与主控制设备通信连接的从控制设备。主控制设备连接三个中继设备和一个第二从控制设备，三个中继设备分别为中继设 备1、中继设备2、中继设备3。其中，中继设备1连接中继设备1_1和中继设备1_2；中继设备3连接中继设备3_1、中继设备3_2和中继设备3_3；中继设备1_2连接中继设备1_1_1、中继设备1_1_2和第一从控制设备1；中继设备3_2连接第一从控制设备2、第一从控制设备3、第一从控制设备4和第一从控制设备5。
主控制设备与其直接连接的设备(可以是中继设备，也可以是第二从控制设备)组成第一网络com1，中继设备与第一从控制设备组成第二网络com2。其中，多联式控制系统可以是多联式空调系统，主控制设备可以是空调室外机，从控制设备可以是空调室内机。
在实际应用中，根据现场的条件或者用户的需求，可以对第一从控制设备手动分配固定的地址，以便可以很好地对应第一从控制设备所在的位置；第一从控制设备也可以自动竞争地址，无需人为设定，安装方便；实际安装第一从控制设备的过程中，根据现场需要，可以进行手动和自动混合安装的情况。
继续参阅附图3，图3示例性的给出了本发明另一种实施例的多联式控制系统的主要结构。在本发明实施例中，多联式控制系统可以包括主控制设备、多个中继设备和多个第一从控制设备和第二从控制设备。主控制设备可以连接三个中继设备和两个第二从控制设备，其中三个中继设备分别是中继设备4、中继设备5和中继设备6，两个第二从控制设备分别是第二从控制设备M和第二从控制设备N，中继设备4与第一从控制设备4_1、第一从控制设备4_2、第一从控制设备4_3和第一从控制设备4_4连接；中继设备5与第一从控制设备5_1、第一从控制设备5_2、第一从控制设备5_3和第一从控制设备5_4连接；中继设备6与第一从控制设备6_1、第一从控制设备6_2、第一从控制设备6_3和第一从控制设备6_4连接。
第一从控制设备向中继设备发起地址请求，请求中继设备为第一从控制设备分配临时地址。在实际应用过程中，每个第一从控制设备的出厂地址默认设置为0#，每个第一从控制设备均向中继设备发起地址请求，中继设备中存储有一定数量的临时地址，根据第一从控制设备发起地址请求的顺序依次为每个第一从控制设备分配临时地址，第一从控制设备从中继设备中竞争临时地址。
具体地，以中继设备4以及与其连接的第一从控制设备为例进行说明，第一从控制设备4_1、第一从控制设备4_2、第一从控制设备4_3和第一从控制设备4_4向中继设备4竞争发送临时地址请求，每次只能有一个第一从控制设备发送临时地址请求成功，假设第一次是第一从控制设备4_2发送临时地址请求成功，中继设备4则为第一从控制设备4_2分配0#的临时地址，剩余的第一从控制设备接着进行临时地址竞争，中继设备4每次只为发送临时地址请求成功的第一从控制设备分配临时地址，直至所有的第一从控制设备均分配到临时地址。其中，分配临时地址可以按照从小到大的顺序进行地址分配。
以此类推，可以得到其他中继设备为与其连接的第一从控制设备分配的临时地址，具体如下表1所示：
表1：中继设备为与其连接的第一从控制设备分配的临时地址
Figure PCTCN2019077990-appb-000001
可选的，本发明所指的临时地址和正式地址可以是以编号排序的通信地址，也可以是网络地址、物理地址等不同的地址类型，能够准确地表征设备所处位置的地址类型均可以使用，本发明实施例并不对地址类型的具体实现方法进行限定。
步骤S102：中继设备根据第一从控制设备的临时地址顺次向主控制设备发起地址请求。
具体地，中继设备既可以存储一定数量的临时地址，并将其分配给第一从控制设备，还可以向主控制设备发起地址请求，请求主控 制设备为其分配正式地址，中继设备再将正式地址分配给对应的第一从控制设备。待中继设备为第一从控制设备分配临时地址后，等待预设时间(如20秒)，中继设备统计第二网络中自动竞争地址的第一从控制设备台数，以便在第一网络中申请对应数量的正式地址。如上表1内容所示，部分第一从控制设备已经分配了正式地址，分配了临时地址的第一从控制设备竞争正式地址。具体地，中继设备可以为第一从控制设备申请8个正式地址，具体内容如下表2所示：
表2：中继设备为与其连接的第一从控制设备申请正式地址的个数
COM2网 申请正式地址的个数
中继设备4 4个
中继设备5 3个
中继设备6 1个
中继设备根据第一从控制设备的临时地址，顺次向主控制设备发起地址请求，每个中继设备每次只为一个第一从控制设备发起地址请求，并且每次按照第一从控制设备的临时地址，顺次发起地址请求。
具体地，中继设备4顺次地为第一从控制设备4_2、第一从控制设备4_3、第一从控制设备4_1、第一从控制设备4_4发起申请正式地址的请求，中继设备5顺次地为与其连接的第一从控制设备5_3、第一从控制设备5_4、第一从控制设备5_1发起申请正式地址的请求，中继设备6为与其连接的第一从控制设备6_4发起申请正式地址的请求。
步骤S103：主控制设备根据第二从控制设备发起地址请求的顺序依次为第二从控制设备分配正式地址。
在实施例的一个优选实施方案中，第二从控制设备与主控制设备直接相连，主控制设备根据第二从控制设备发起地址请求的顺序依次为第二从控制设备分配正式地址。以第二从控制设备的数量为两个为例进行说明，主控制设备为第二从控制设备分配正式地址的情况如下表3所示：
表3：主控制设备为第二从控制设备分配的正式地址
COM1网 正式地址
第二从控制设备M(自动) 0#
第二从控制设备N(手动) 3#
步骤S104：主控制设备根据预设的第一预留地址和中继设备发起地址请求的顺序将正式地址分配至中继设备对应的第一从控制设备。
具体地，第一预留地址取决于临时地址以及第一从控制设备和第二从控制设备是否已经分配了正式地址。第一预留地址是在第二从控制设备和部分第一从控制设备分配了正式地址后，主控制设备根据临时地址的数量预留出与临时地址数量相同的正式地址。
为了可以对主控制设备中的可用地址进行高效地利用，在分配正式地址前，可以判断第二从控制设备是否都分配了正式地址，若是，则获取第二从控制设备的正式地址；检测是否存在已经分配了正式地址的第一从控制设备，若是，则获取第一从控制设备的正式地址。第一预留地址是在主控制设备得到第二从控制设备和部分第一从控制设备的正式地址后，根据预设的地址段、临时地址的数量以及第二从控制设备和部分第一从控制设备的正式地址，确定需要为竞争正式地址的第一从控制设备预留的地址。
下面以图3所示的多联式控制系统以及表1和表3为例对中继设备发起地址请求的过程进行说明：
主控制设备中已有的正式地址：0#、1#、3#、5#、6#、9#，中继设备竞争剩余的正式地址，其中，剩余的正式地址可以是按从小到大或者从大到小的顺序排列的地址。
第1轮竞争：
第一从控制设备将临时地址竞争发送至中继设备，中继设备根据临时地址为对应的第一从控制设备申请正式地址。具体地，中继设备4、中继设备5和中继设备6向主控制设备竞争发送正式地址请求，每次只能有一个中继设备发送正式地址请求成功，假设第一次是中继设备5发送正式地址请求成功，主控制设备则为中继设备5对应的第一从控制设备5_3分配2#的正式地址；假设第二次是中继设备4发送正式地址请求成功，主控制设备则为中继设备4对应的第一从控制设备4_2分配4#的正式地址；剩余的中继设备接着进行正式地址竞争，假设第三次是中继设备6发送正式地址请求成功，主控制设备则为中继设备对应的第一从控制设备6_4分配7#的正式地址，中继设备6与其连接的所有第一从控制设备均分配到正式地址，中继设备6不参加后续的竞争。
主控制设备每次只为发送正式地址请求成功的中继设备分配正式地址，直至每个中继设备每次正式地址请求都分配到正式地址，当每个中继设备均竞争发送正式地址请求后，则第1轮竞争结束，接着进行第2轮竞争，直至每个中继设备连接的第一从控制设备均分配到正式地址。
第2轮竞争：
中继设备4、中继设备5继续向主控制设备竞争发送正式地址请求，假设第2轮竞争中，第一次是中继设备5发送正式地址请求成功，主控制设备则为中继设备5对应的第一从控制设备5_4分配8#的正式地址；接着中继设备4向主控制设备竞争发送正式地址请求，主控制设备则为中继设备4对应的第一从控制设备4_3分配10#的正式地址。
第3轮竞争：
中继设备4、中继设备5继续向主控制设备竞争发送正式地址请求，假设第2轮竞争中，第一次是中继设备4发送正式地址请求成功，主控制设备则为中继设备4对应的第一从控制设备4_1分配11#的正式地址；急着中继设备5向主控制设备竞争发送正式地址请求，主控制设备则为中继设备5对应的第一从控制设备5_1分配12#的正式地址。中继设备5与其连接的所有第一从控制设备均分配到正式地址，中继设备5不参加后续的竞争
第4轮竞争：
中继设备4继续向主控制设备竞争发送正式地址请求，主控制设备为中继设备4对应的第一从控制设备4_4分配12#的正式地址。至此，所有的中继设备连接的第一从控制设备均分配到正式地址，竞争结束，具体结果如下表4所示：
表4：中继设备为其对应的第一从控制设备竞争正式地址的结果图

在本发明实施例的一种优选实施方案中，每轮竞争结束后，均等待预设时间(如20秒)，等待通信稳定后再进行下一轮竞争，以便进行地址确认。
在本发明实施例的一种优选实施方案中，在“主控制设备根据预设的第一预留地址和中继设备发起地址请求的顺序将正式地址分配至中继设备对应的第一从控制设备”的步骤之后，中继设备检测每个临时地址对应的正式地址与第二从控制设备的正式地址是否存在冲突，若是，则获取存在冲突的正式地址所对应的临时地址，并根据第一预留地址重新为所获取的临时地址分配对应的正式地址，进一步确保第一从控制设备和第二从控制设备正式地址的唯一性。
步骤S105：中继设备根据临时地址顺次将正式地址分配至相应的第一从控制设备。
中继设备根据第一从控制设备的临时地址从主控制设备竞争到正式地址后，按第一从控制设备的临时地址顺次将其分配至第一从控制设备。
基于主控制设备根据临时地址的顺序依次为中继设备对应的第一从控制设备分配正式地址的策略，可以建立“临时地址-正式地址”的对应关系。中继设备在运行过程中，可以检测是否增设了新的第一从控制设备，若是，主控制设备根据预设的第二预留地址、中继设备发起地址请求的顺序以及“临时地址-正式地址”的对应关系为中继设备依次分配临时地址对应的正式地址，中继设备根据临时地址顺次将正式地址分配至相应的新增设的第一从控制设备。
其中，第二预留地址取决于临时地址和增设的第一从控制设备之前，第一从控制设备和第二从控制设备的正式地址。第二预留地址 是在第一从控制设备和第二从控制设备分配了正式地址以及为临时地址预留出与临时地址数量相同的正式地址后，主控制根据增设的第一从控制设备预留出与增设的第一从控制设备数量相同的正式地址。
在本发明实施方案的优选实施方案中，中继设备可以将第一从控制设备的参数发送至主控制设备。其中，第一从控制设备的参数可以包括电机风速、设定温度、膨胀阀开度等，主控制设备可以通过中继设备将地址发送至第一从控制设备。通过中继设备连接主控制设备和第一从控制设备，可以在保持主控制设备和第一从控制设备芯片不变的情况下，延长通信距离，中继设备可以包括至少两个芯片，一个芯片与主控制设备通信，另一个芯片与第一从控制设备通信，假设主控制设备和第一从控制设备直接连接的情况下通信距离是1000米，增加了中继设备后，通信距离可以增加至4000米。
