附图说明
为了更清楚地说明本申请实施例的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。
如图1所示的中央空调系统,包括室外机、室内机、线控器、集控器、云服务器和用户终端,当用户需要用华氏度操作温度时,系统需要同步切换线控器以及用户终端的温度单位;通常情况下,中央空调系统的线控器的温度设定或显示是以0.5度或1度为间隔上下调节的,且多数情况下华氏度是按照1度整度上下调节的,系统内部温度的传递可以做到0.5度的传输,而鉴于摄氏度与华氏度之间的线性但非整数对应关系,在同步切换温度单位时可能会出现显示不同步的问题,例如用户在线控器端按照华氏度操作65℉,在其转换成摄氏度在系统内传输到用户终端,再经摄氏度到华氏度的转换后,显示可能是66℉,这种情况下,一旦用户在切换之前通过用户终端设定温度的场景控制时,则会出现控制误差较大或控制失败的情况。
在本申请的一些实施例中,为解决上述问题,通过建立华氏度与摄氏度 数值映射表,通过查表方式获取华氏度与摄氏度的转换关系的方式来保证显示同步及控制同基准,但随着控制需求的扩展,表的范围不断增加,占据的存储空间也增大,对表的要求也就越高,一旦出错,不易发觉且不易扩展和移植。
本申请提出的中央空调系统,旨在实现线控器端和用户终端温度的同步切换,避免查表法存在的易出差错问题,且使得目前以摄氏温度工作的系统方便扩展和移植。
如图2和图5所示,本申请提出的中央空调系统,包括室外机1、室内机2、线控器3、集控器4、云服务器5和用户终端6;线控器3和集控器4均连接室内机2,集控器4与云服务器5互联,用户终端6与云服务器5互联。
本申请提出的中央空调系统还包括华氏度转换模块7,其用于从系统中获取当前传输的摄氏温度数据,采用华氏度摄氏度标准转换公式C=(F-32)÷1.8将其转换为第一华氏温度数据,再按照四舍五入将第一华氏温度数据转换为目标华氏温度数据。
转化的目标华氏温度数据发送给线控器3、用户终端6同步切换显示,
如下表一所示的华氏度转换:
表一
Figure PCTCN2021081679-appb-000001
Figure PCTCN2021081679-appb-000002
从表一中的数据可以看出,在系统内部的摄氏温度数据不同的情况下,对应计算的华氏温度数据可能存在重叠,例如当摄氏温度为2.5℃或3.0℃,对应显示的华氏度均为37℉,摄氏温度为7.5℃或8.0℃,对应显示的华氏度均为46℉,但不论系统内的摄氏温度如何改变,线控器3端和用户终端6显示的华氏温度数据是同步切换的,不影响用户体验。
可见,基于上述提出的中央空调系统,不论在线控器3端,还是在用户终端6,按照相同的转换方式将系统内部传输的摄氏温度数据转换为华氏温度数据,使得线控器3端和用户终端6的显示同步,但在系统内部,无论用户如何切换,始终传输的都是摄氏温度数据,不改变当前中央空调系统的温度传输框架,对整体系统影响最小,可以快速实现海外产品对华氏度需求的切换或国内产品到海外产品的过渡,无需查表,不易出错,解决了现有通过查表法确保系统的摄氏度与华氏度显示同步存在的易出差错、不易扩展和移植的问题。
上述华氏度转换模块7可以单独开发的模块应用于线控器3中和用户终端6中,如图2所示,对于整个中央空调系统,仍旧以摄氏温度数据实施控制,线控器3和用户终端4从系统获取当前传输的摄氏温度值,基于华氏度转换模块将摄氏温度转换为华氏温度后进行显示。
在本申请实施例中,上述华氏度转换模块7应用于云服务器5中,如图5所示,整套中央空调系统无需做任何改动,仍旧以摄氏温度数据实施控制,在云服务器5端,通过程序升级或植入等方式安装华氏度转换模块7,云服务器5从系统获取当前传输的摄氏温度数据,将其转换为目标华氏温度,分别将其发送给集控器4和用户终端6,集控器4再基于集控器4-室内机2-线控器3的连接通路将其发送给线控器3,从而实现了线控器3和用户终端6的同步切换显示。
在本申请实施例中,该中央空调系统还包括摄氏度转换模块8,分别应用于线控器3和用户终端6中,用于接收用户通过线控器3或用户终端6设定的华氏温度数据,采用上述华氏度摄氏度标准转换公式将用户输入的华氏温度数据转换成第一摄氏温度数据,基于下述给出的比较模型将第一摄氏温度数据的小数部分进行转换:
该比较模型为:设定一个第一阈值H1和一个第二阈值H2,第一阈值H1小于第二阈值H2,即H1<H2;在第一摄氏温度数据的小数部分小于第一阈值H1时,将第一摄氏温度数据的小数部分转换为第一基准值J1;在第 一摄氏温度数据的小数部分大于等于第一阈值H1、且小于第一阈值H1与第二阈值H2的和H1+H2时,将第一摄氏温度数据的小数部分转换为第二基准值J2;在第一摄氏温度数据的小数部分大于等于第一阈值H1与第二阈值H2的和H1+H2时,将第一摄氏温度数据的小数部分转换为第三基准值J3。
在本申请实施例中,适用于中央空调系统内部传输的摄氏温度数据以最小间隔0.5℃传输时,将第一阈值设置为0.3℃,第二阈值设置为0.5℃,第一基准值J1=0,第二基准值J2=0.5,第三基准值J3=1;则若第一摄氏温度数据的小数部分小于0.3℃,则将第一摄氏温度数据的小数部分转换为0,若第一摄氏温度数据的小数部分大于等于0.3℃且小于0.3℃+0.5℃,则将第一摄氏温度数据的小数部分转换为0.5℃,若第一摄氏温度数据的小数部分大于等于0.3℃+0.5℃,则将第一摄氏温度数据的小数部分转换为1℃。
在将第一摄氏温度数据的小数部分转换为第一基准值J1、第二基准值J2或第三基准值J3后,摄氏度转换模块8通过计算第一摄氏温度数据的整数部分T与转换的第一基准值J1、第二基准值J2或第三基准值J3的和将第一摄氏温度数据转换为目标摄氏温度数据T+J1、T+J2或T+J3。
如下表二所示的实施例:
表二
Figure PCTCN2021081679-appb-000003
由表二内容可以看出,设置不同华氏度时会出现系统内部摄氏温度的缺 失,如华氏度36°F和华氏度37°F会出现摄氏度2.5℃的缺失,华氏度45°F和华氏度46°F会出现摄氏度7.5℃的缺失,但系统内部传输的摄氏温度不影响线控器3端和用户终端6对华氏温度的连续设定,缺失的摄氏度问题也不会对用户造成明显影响。
基于上述的中央空调系统,本申请对应提出其控制方法,如图3所示,包括如下步骤:
步骤S31:获取中央空调系统内部当前传输的摄氏温度数据。
在本申请的中央空调系统中,不论线控器端和用户终端是应用摄氏温度还是华氏温度,在系统内部传输处理的始终是摄氏温度。
步骤S32:采用华氏度摄氏度标准转换公式将当前传输的摄氏温度数据转换为第一华氏温度数据。
采用标准公式C=(F-32)÷1.8将摄氏温度转换为华氏温度数据,定为第一华氏温度数据。
步骤S33:将第一华氏温度数据按照四舍五入计算得到目标华氏温度数据。
如上表一所示,将通过标准公式转换的第一华氏温度数据采用四舍五入方法得到最终要应用的目标华氏温度数据。
步骤S34:将目标华氏温度数据发送给线控器和/或用户终端。
目标华氏温度最终发送给线控器和/用户终端应用,包括但不限定于显示、计算、设定、存储等等。
在本申请实施例中,上述方法可通过程序升级或补丁模块添加于云服务器,在云服务器中执行,进而由云服务器同步发送给线控器和用户终端实施应用。
在本申请一些实施例中,上述方法还可通过程序升级或补丁模块分别单独添加于线控器和用户终端应用,在线控器和用户终端中单独执行,但均是从系统内部获取传输的摄氏温度数据。
基于此种应用模式,在本申请一些实施例中,该中央空调系统的控制方法,如图4所示,还包括:
步骤S41:接收输入的华氏温度数据。
用户使用线控器或用户终端采用华氏温度对中央空调实施设定和控制。
步骤S42:采用华氏度摄氏度标准转换公式将输入的华氏温度数据转换为第一摄氏温度数据。
采用公式C=(F-32)÷1.8将用户输入的华氏温度数据转换为第一摄氏 温度数据。
步骤S43:基于比较模型将第一摄氏温度数据的小数部分转换为第一基准值、第二基准值或第三基准值。
比较模型为:
1、设定第一阈值H1和第二阈值H2;
2、在第一摄氏温度数据的小数部分小于第一阈值H1时,将第一摄氏温度数据的小数部分转换为第一基准值J1;
3、在第一摄氏温度数据的小数部分大于等于第一阈值H1、且小于第一阈值与第二阈值的和H1+H2时,将第一摄氏温度数据的小数部分转换为第二基准值J2;
4、在第一摄氏温度数据的小数部分大于等于第一阈值与第二阈值的和H1+H2时,将第一摄氏温度数据的小数部分转换为第三基准值J3。
上述第一阈值H1、第二阈值H2、第一基准值J1、第二基准值J2和第三基准值J3根据中央空调系统的实际应用情况设定,例如在惯行的摄氏度应用情况下,也即在线控器端和用户终端按照1华氏度为调节间隔对系统实施设定,在系统内部按照最小间隔为0.5℃实施传输和处理的应用情况下,设置H1=0.3,H2=0.5,J1=0,J2=0.5,J3=1;在其他一些应用情况下,上述参数按照实际情况根据经验或实验值设定即可,本申请不予赘述。
步骤S44:通过计算第一摄氏温度数据的整数部分与转换的第一基准值、第二基准值或第三基准值的和,将第一摄氏温度数据转换为目标摄氏温度数据。
也即,目标摄氏温度数据=第一摄氏温度数据的整数部分T+J1/J2/J3。
在本申请的一些实施例中,本申请提出的中央空调及其控制方法,通过华氏度转换模块从系统内部获取当前传输的摄氏温度数据,现将其采用华氏度摄氏度标准转换公式转换为第一华氏温度数据,再将第一华氏温度数据按照四舍五入计算得到目标华氏温度数据,目标华氏温度数据发送给线控器和/或用户终端;基于上述,不论在线控器端,还是在用户终端,按照相同的转换方式将系统内部传输的摄氏温度数据转换为华氏温度数据,使得线控器端和用户终端的显示同步,但在系统内部,无论用户如何切换,始终传输的都是摄氏温度数据,不改变当前中央空调系统的温度传输框架,对整体系统影响最小,可以快速实现海外产品对华氏度需求的切换或国内产品到海外产品的过渡,无需查表,不易出错,解决了现有通过查表法确保系统的摄氏度与华氏度显示同步存在的易出差错、不易扩展和移植的问题。
在本申请的一些实施例中,针对用户采用线控器或用户终端对空调系统实施华氏温度调节时,通过比较模型的应用,能够实现华氏温度的连续设定,系统内仍然保持摄氏温度数据的传输和应用,提高了用户的使用体验。
需要说明的是,在具体实现过程中,上述的中央空调系统的控制方法可以通过硬件形式的处理器执行存储器中存储的软件形式的计算机执行指令实现,此处不予赘述,而上述中央空调系统所执行的动作所对应的程序均可以以软件形式存储于系统的计算机可读存储介质中,以便于处理器调用执行以上各个模块对应的操作。
上文中的计算机可读存储介质可以包括易失性存储器,例如随机存取存储器;也可以包括非易失性存储器,例如只读存储器、快闪存储器、硬盘或固态硬盘;还可以包括上述种类的存储器的组合。
上文所提到的处理器,也可以是多个处理元件的统称。例如,处理器可以为中央处理器,也可以为其他通用处理器、数字信号处理器、专用集成电路、现场可编程门阵列或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等。通用处理器可以是微处理器或者可以是任何常规的处理器等等,还可以为专用处理器。
以上仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以权利要求的保护范围为准。
