Description

用于控制通讯补偿的方法及装置、空调
本申请基于申请号为201910471255.9、申请日为2019年05月31日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及空调器技术领域，例如涉及一种用于控制通讯补偿的方法及装置、空调。
背景技术
空调多联机组包括室内机和室外机，如一拖多的空调机组的室外机和室内机之间往往要进行信息通讯。目前，多联机组的室外机，单模块的匹数已经可以做到32匹，如果四个模块实现组合装配，一套室外机机组的能力就可以达到128匹，可连接128台室内机。从多联机机组的发展趋势来看，外机机组的匹数会继续做大，这样一套室外机机组可以连接128台以上的室内机。连接的室内机台数越多，室外机与末端室内机之间的距离就会越长。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：在室外机与室内机通过Homebus(通讯总线)通讯的过程中，由于长距离通讯容易发生信号折射干扰，空调多联机组中室外机与室内机的距离越长，Homebus通讯的信号衰减就越严重，从而无法保障空调多联机组室内机、室外机之间的通讯稳定。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。
本公开实施例提供了一种用于控制通讯补偿的方法、装置和空调室外机，以解决相关技术中在Homebus通讯过程中，由于通讯距离较长，出现信号衰减严重，造成通讯不稳定的问题。
在一些实施例中，所述方法包括：根据数据在通信链路上传输的脉冲数据的时间长度，确定所述通信链路的长度级别；
根据所述通信链路的长度级别，确定通讯补偿的补偿策略。
在一些实施例中，所述装置包括：长度级别确定模块，被配置为根据数据在通信链路上传输的脉冲数据的时间长度，确定所述通信链路的长度级别；补偿模块，被配置为根据所述通信链路的长度级别，确定通讯补偿的补偿策略。
在一些实施例中，所述空调室外机包括：上述的用于控制通讯补偿的装置。
本公开实施例提供的一些技术方案可以实现以下技术效果：
根据数据在通信链路上传输的脉冲数据的时间长度确定通讯链路的长度级别，根据长度级别确定通讯补偿的补偿策略，通过对数据进行时间补偿，避免了因通讯距离过长造成的衰减情况，提高了长距离Homebus通讯的稳定性。
以上的总体描述和下文中的描述仅是示例性和解释性的，不用于限制本申请。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
本公开实施例提供了一种用于控制通讯补偿的方法，如图1所示，包括：
S101，根据数据在通信链路上传输的脉冲数据的时间长度，确定所述通信链路的长度级别；
S102，根据所述通信链路的长度级别，确定通讯补偿的补偿策略。
