Description

空调通信的控制方法、装置、通信系统和可读存储介质
本申请要求于2020年12月09日提交中国专利局、申请号为“202011433039.4”、申请名称为“空调通信的控制方法、装置、通信系统和可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信控制技术领域，具体而言，涉及一种空调通信的控制方法、装置、通信系统和可读存储介质。
背景技术
相关技术方案中，空调以及其他通信系统中的电感、电容、电阻以及信号反射等受到干扰时，会导致检测得到的信号发生畸变。
具体地，空调以及其他通信系统中MCU的采样方式一般是将晶振的频率倍频处理，采样一定次数之后，读取采样的数据，如识别通信信号的高低电平，空调以及其他通信系统中MCU会设置一个检测阈值，在出现如上文中的畸变时，会使得MCU读取得到的数据出现错误。
以485通信为例，检测阈值为-200mV～200mV，在总线上的电压值大于200mV时，认为从总线上识别到“1”，当总线上的电压值小于-200mV，认为从总线上识别到“0”，在出现如上文中的畸变时，如图10所示，正常情况下总线差分信号的电压值为0V，通信接口芯片输出信号为“1”,当总线信号受到干扰发生波动，通信接口芯片就会输出错误的信号“0”。
如图11所示，对于通信线过长或电阻、电容影响，在通信速率较快时，总线上的信号传输变化缓慢，根据通信接口芯片的检测阈值，如485通信的-200mV～200mV，通信接口芯片输出“1”的时间会变短，最终造成通信的质量下降。
申请内容
本申请旨在至少解决现有技术或相关技术中存在的技术问题之一。
为此，本申请的第一个方面在于，提供了一种空调通信的控制方法。
本申请的第二个方面在于，提供了一种空调通信的控制装置。
本申请的第三个方面在于，提供了一种通信系统。
本申请的第四个方面在于，提供了一种可读存储介质。
有鉴于此，根据本申请的第一个方面，本申请提供了一种空调通信的控制方法，其中，空调与总线连接，空调通信的控制方法包括：获取总线的电压信号；基于电压信号满足空调的供电电压和总线上的基准电压的比对条件，确定电压信号中的电压上升沿斜率以及电压下降沿斜率；基于电压上升沿斜率和电压下降沿斜率满足斜率比对条件，对电压信号进行时间对比，得到处理后的电压信号；确定数据模型库中与处理后的电压信号一致的目标数据模型；输出目标数据模型对应的数据信息。
在本申请的技术方案中，通过对总线中的电压信号进行检测，以得到总线中的电压信号所对应的数据模型，并将该数据模型与存储的数据模型库中的模型进行比对，在比对一致的情况下，输出比对一致的数据模型中的数据信息(即本申请中的目标数据模型中的数据信息)。
具体地，通过对获取总线上采集的电压信息进行电压比对，电压上升沿斜率、电压下降沿斜率的斜率比对实现了对电压数据的筛选，并通过时间对比的方式实现了对采集得到的数据的信号还原，在此过程中，采用模型对比的方式对总线上的电压信号进行识别，减少了因空调以及其他通信系统中的电感、电容、电阻以及信号反射等受到干扰时，导致的检测得到的信号数据异常。
另外，本申请提供的上述技术方案中的空调通信的控制方法还可以具有如下附加技术特征：
在上述任一技术方案中，基于电压信号中任一采样电压值小于或等于空调的供电电压，且与基准电压的差值大于预设阈值，确定电压信号满足空调的供电电压、总线上的基准电压的比对条件。
在该技术方案中，具体限定了电压信号是否满足空调的供电电压、总线上的基准电压的比对条件的判断过程。
通常情况下，空调会通过一个通信芯片与总线连接，以实现总线上的 信号的获取，而该芯片在使用时，芯片所采集的电压信号所在的区间会小于其供电电压，故为了减少因总线上的电压信号对应的电压值过高，如超过其供电电压，致使空调无法对其进行采集以及还原，本申请的技术方案中，在进行电压比对时，限定任一采样电压值小于或等于供电电压，以便可以准确地对总线上的电压信号进行矫正，降低输出错误信号的几率。
此外，由于本申请的技术方案需要对电压上升沿斜率和电压下降沿斜率满足斜率比对条件进行比对，若采集得到的电压信号所对应的电压值过低，则会对还原的精度产生影响，更有甚者，致使信号无法矫正。
为了解决上述问题，本申请的技术方案具体限定了任一采样电压值与基准电压之间的差值要足够大，如大于预设阈值，以确保才采样电压值足够大，进而确保了还原的精度。
在上述任一技术方案中，预设阈值可以根据实际需要进行设定，举例来说，在通信芯片的供电电压为3.3伏特时，预设阈值的取值可以是0.5伏特，此时基准电压不能超过2.5伏特。
在上述任一技术方案中，若电压信号不满足空调的供电电压、总线上的基准电压的比对条件时，输出错误数据模型，以提醒用户进行处理。
在上述任一技术方案中，具体限定了电压上升沿斜率和电压下降沿斜率是否满足斜率比对条件的判定过程，具体地，确定电压上升沿斜率所对应的第一幅值和电压下降沿斜率对应的第二幅值；基于第一幅值与第二幅值之间的比值大于0.5、且小于2，确定电压上升沿斜率和电压下降沿斜率满足斜率比对条件。
在该技术方案中，通过将确定的第一幅值和第二幅值进行比较，以便确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，对于差异较大的情况，认为电压信号不满足斜率比对条件，此时，输出错误数据模型，以提醒用户进行处理。
具体地，为了便于对电压信号是否满足斜率比对条件进行量化处理，本申请的技术方案通过比较斜率的幅值的大小关系来确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，具体地，在第一幅值和第二幅值之间相差不超过一半的情况下，认为电压上升沿的波形和电压下降沿的 波形之间的差异较小，即满足斜率比对条件，考虑到第一幅值可以大于第二幅值，也可以小于第二幅值，若单独划分比较情况，则需要处理的数据较多。
为了减少数据处理的量，本申请的技术方案通过确定第一幅值与第二幅值之间的比值的波动范围来量化第一幅值和第二幅值之间相差不超过一半这一判断条件，具体地，该比值需要大于0.5、且小于2，在此过程中，在对电压上升沿的波形和电压下降沿的波形之间的差异的过程中，仅需判断该比值是否大于0.5且小于2即可实现该差异的判定，降低了比对难度。
在上述任一技术方案中，确定电压信号中的电压上升沿斜率以及电压下降沿斜率的步骤，具体包括：基于总线的采样电压值大于基准电压，记录采样电压值为第一电压值；基于总线的采样电压值大于基准电压的持续时长大于或等于第一预设时长，记录采样电压值为第二电压值；将第二电压值与第一电压值的比值作为电压上升沿斜率；查找以总线的采样电压值为最大电压值作为开始时刻，第一预设时长后记录的采样电压值为第三电压值；将最大电压值与第三电压值的比值作为电压下降沿斜率。
在该技术方案中，空调是周期性在总线上采集数据，若在采集得到的电压值并确定的电压差值之后，将计算其与电压差值所对应的时间的比值，以得到对应的斜率，考虑到本申请的技术方案是通过比较第一幅值与第二幅值之间的比值大小来确定是否满足斜率比对条件，在电压差值所对应的时间是相同的情况下，可以将第二电压值和第一电压值的比值看作电压上升沿斜率，同理，将最大电压值和第三电压值的比值看作电压下降沿斜率，以此来降低空调所需要处理的数据量。
在上述任一技术方案中，对电压信号进行时间对比，得到处理后的电压信号的步骤，具体包括：确定以总线的采样电压值大于基准电压所对应的时刻作为开始时刻，第二预设时长后的第一时刻；确定以总线的采样电压值为最大电压值对应的时刻作为开始时刻第二预设时长后的第二时刻；根据第一时刻和第二时刻确定第一时长；根据第一时长与二进制数据中的第一个数码对应的时长确定第一时长代表的第一个数码的个数；确定以总线的采样电压值再次大于基准电压所对应的时刻作为开始时刻，第二预设 时长后的第三时刻；根据第三时刻和第二时刻确定第二时长；根据第二时长与二进制数据中的第二个数码对应的时长确定第二时长代表的第二个数码的个数；根据第一个数码的个数、第二个数码的个数、第一个数码和第二个数码确定处理后的电压信号。
通常情况下，确定总线上电压信号的方式是根据总线上高电平的持续时间或低电平的持续时间来确定二进制数据中的第一个数码和第二个数码的个数，由于总线上存在信号干扰，空调采集得到的电压波动较大，精度较低。
为了解决上述问题，本申请的技术方案采用时间对比的方式来确定二进制数据中的第一个数码和第二个数码的个数，并根据第一个数码的个数和第二个数码的个数对电压信号进行数据还原，在此过程中，减少了上述情况对读取信号的影响，确保了信号的可信度。
在上述任一技术方案中，基于第一时长与M个第一个数码对应的时长的差值小于或等于设定值，确定第一时长对应M个连续的第一个数码；基于第二时长与N个第二个数码对应的时长的差值小于或等于设定值，确定第二时长对应N个连续的第二个数码，其中，M，N为自然数。
在该技术方案中，考虑到由于总线过长、或与总线连接的电容或者如与总线连接的采样电阻的影响，总线上的电压信号的长度会发生变化，为了消除该影响，给出第一时长与M个第一个数码对应的时长之间的波动区间，具体地，通过计算第一时长与M个第一个数码对应的时长的差值，并将该差值与设定值进行比较，以便判断该波动区间是否超出设定值。若不超过设定值时，认定第一时长对应M个连续的第一个数码，其中，可以理解的是，即第一时刻至第二时刻之间的电压信号对应M个连续的第一个数码，同理，第二时刻至第三时刻之间的电压信号对应N个连续的第二个数码，在上述过程中，实现了对采集得到的电压信号的还原，以便得到处理后的电压信号。
在上述任一技术方案中，空调通信的控制方法还包括：获取空调的波特率以及总线上的实际通信时间；根据波特率和实际通信时间确定第一个数码对应的时长以及第二个数码对应的时长。
在该技术方案中，考虑到空调进行通信的波特率不同，第一个数码对应的时长以及第二个数码对应的时长也会不同，为了确保目标数据模型的准确性，需要对第一个数码对应的时长以及第二个数码对应的时长进行标定，根据空调的波特率以及总线上的实际通信时间来确定第一个数码对应的时长以及第二个数码对应的时长。
在上述任一技术方案中，实际通信时间即总线上的理论通信时间与第一等待时间、第二等待时间的差值，其中，理论通信时间可以理解为在总线上的电压值大于或等于基准电压的时长，第一等待时长为总线上的电压值大于基准电压的时长为第一等待时间之后，才开始进行获取总线上的采样电压值，同理，第二等待时间为不进行采样的时间，其对应理论通信时间的尾部。
在其中一个实施例中，第一等待时间、第二等待时间属于不对总线上的电压信号进行采样的时间，其具体数值可以预先进行设定。
在本申请第二方面的实施例中，提出了一种空调通信的控制装置，其中，空调与总线连接，空调通信的控制装置包括：获取单元，用于获取总线的电压信号；确定单元，用于基于电压信号满足空调的供电电压和总线上的基准电压的比对条件，确定电压信号中的电压上升沿斜率以及电压下降沿斜率；基于电压上升沿斜率和电压下降沿斜率满足斜率比对条件，对电压信号进行时间比对，得到处理后的电压信号；确定数据模型库中与处理后的电压信号一致的目标数据模型；输出单元，用于输出目标数据模型对应的数据信息。
本申请的技术方案提出了一种空调通信的控制装置，其具体包括获取单元、确定单元以及输出单元。其中，通过对总线中的电压信号进行检测，以得到总线中的电压信号所对应的数据模型，并将该数据模型与存储的数据模型库中的模型进行比对，在比对一致的情况下，输出比对一致的数据模型中的数据信息(即本申请中的目标数据模型中的数据信息)。
具体地，通过对获取总线上采集的电压信息进行电压比对，电压上升沿斜率、电压下降沿斜率的斜率比对实现了对电压数据的筛选，并通过时间对比的方式实现了对采集得到的数据的信号还原，在此过程中，采用模 型对比的方式对总线上的电压信号进行识别，减少了因空调以及其他通信系统中的电感、电容、电阻以及信号反射等受到干扰时，导致的检测得到的信号数据异常。

在上述任一技术方案中，确定单元具体用于：基于电压信号中任一采样电压值小于或等于空调的供电电压，且与基准电压的差值大于预设阈值，确定电压信号满足空调的供电电压、总线上的基准电压的比对条件。
在该技术方案中，具体限定了电压信号是否满足空调的供电电压、总线上的基准电压的比对条件的判断过程。
通常情况下，空调会通过一个通信芯片与总线连接，以实现总线上的信号的获取，而该芯片在使用时，芯片所采集的电压信号所在的区间会小于其供电电压，故为了减少因总线上的电压信号对应的电压值过高，如超过其供电电压，致使空调通信无法对其进行采集以及还原，本申请的技术方案中，在进行电压比对时，限定任一采样电压值小于或等于供电电压，以便可以准确地对总线上的电压信号进行矫正，降低输出错误信号的几率。
此外，由于本申请的技术方案需要对电压上升沿斜率和电压下降沿斜率满足斜率比对条件进行比对，若采集得到的电压信号所对应的电压值过低，则会对还原的精度产生影响，更有甚者，致使信号无法矫正。
为了解决上述问题，本申请的技术方案具体限定了任一采样电压值与基准电压之间的差值要足够大，如大于预设阈值，以确保才采样电压值足够大，进而确保了还原的精度。
在上述任一技术方案中，预设阈值可以根据实际需要进行设定，举例来说，在通信芯片的供电电压为3.3伏特时，预设阈值的取值可以是0.5伏特，此时基准电压不能超过2.5伏特。
在上述任一技术方案中，若电压信号不满足空调的供电电压、总线上的基准电压的比对条件时，输出错误数据模型，以提醒用户进行处理。
在上述任一技术方案中，确定单元具体用于：确定电压上升沿斜率所对应的第一幅值和电压下降沿斜率对应的第二幅值；基于第一幅值与第二 幅值之间的比值大于0.5、且小于2，确定电压上升沿斜率和电压下降沿斜率满足斜率比对条件。
在该技术方案中，通过将确定的第一幅值和第二幅值进行比较，以便确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，对于差异较大的情况，认为电压信号不满足斜率比对条件，此时，输出错误数据模型，以提醒用户进行处理。
具体地，为了便于对电压信号是否满足斜率比对条件进行量化处理，本申请的技术方案通过比较斜率的幅值的大小关系来确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，具体地，在第一幅值和第二幅值之间相差不超过一半的情况下，认为电压上升沿的波形和电压下降沿的波形之间的差异较小，即满足斜率比对条件，考虑到第一幅值可以大于第二幅值，也可以小于第二幅值，若单独划分比较情况，则需要处理的数据较多。
为了减少数据处理的量，本申请的技术方案通过确定第一幅值与第二幅值之间的比值的波动范围来量化第一幅值和第二幅值之间相差不超过一半这一判断条件，具体地，该比值需要大于0.5、且小于2，在此过程中，在对电压上升沿的波形和电压下降沿的波形之间的差异的过程中，仅需判断该比值是否大于0.5且小于2即可实现该差异的判定，降低了比对难度。
在上述任一技术方案中，确定单元具体用于：基于总线的采样电压值大于基准电压，记录采样电压值为第一电压值；基于总线的采样电压值大于基准电压的持续时长大于或等于第一预设时长，记录采样电压值为第二电压值；将第二电压值与第一电压值的比值作为电压上升沿斜率；查找以总线的采样电压值为最大电压值作为开始时刻，第一预设时长后记录的采样电压值为第三电压值；将最大电压值与第三电压值的比值作为电压下降沿斜率。
在该技术方案中，空调是周期性在总线上采集数据，若在采集得到的电压值并确定的电压差值之后，将计算其与电压差值所对应的时间的比值，以得到对应的斜率，考虑到本申请的技术方案是通过比较第一幅值与第二幅值之间的比值大小来确定是否满足斜率比对条件，在电压差值所对应的 时间是相同的情况下，可以将第二电压值和第一电压值的比值看作电压上升沿斜率，同理，将最大电压值和第三电压值的比值看作电压下降沿斜率，以此来降低空调所需要处理的数据量。
在上述任一技术方案中，确定单元具体用于：确定以总线的采样电压值大于基准电压所对应的时刻作为开始时刻，第二预设时长后的第一时刻；确定以总线的采样电压值为最大电压值对应的时刻作为开始时刻第二预设时长后的第二时刻；根据第一时刻和第二时刻确定第一时长；根据第一时长与二进制数据中的第一个数码对应的时长确定第一时长代表的第一个数码的个数；确定以总线的采样电压值再次大于基准电压所对应的时刻作为开始时刻，第二预设时长后的第三时刻；根据第三时刻和第二时刻确定第二时长；根据第二时长与二进制数据中的第二个数码对应的时长确定第二时长代表的第二个数码的个数；根据第一个数码的个数、第二个数码的个数、第一个数码和第二个数码确定处理后的电压信号。
通常情况下，确定总线上电压信号的方式是根据总线上高电平的持续时间或低电平的持续时间来确定二进制数据中的第一个数码和第二个数码的个数，由于总线上存在信号干扰，空调采集得到的电压波动较大，精度较低。

具体实施方式
为了能够更清楚地理解本申请的上述方面、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
实施例一
如图1所示，根据本申请的第一个方面，本申请提供了一种空调通信的控制方法，其中，空调与总线连接，空调通信的控制方法包括：
步骤102，获取总线上的电压信号；
步骤104，在电压信号符合空调的供电电压以总线上的基准电压的比对条件的情况下，确定电压信号中的电压上升沿斜率以及电压下降沿斜率；
步骤106，在电压上升沿斜率和电压下降沿斜率符合斜率比对条件的情况下，对电压信号进行时间对比，得到处理后的电压信号；
步骤108，确定数据模型库中与处理后的电压信号一致的目标数据模型；
步骤110，输出目标数据模型对应的数据信息。
在该实施例中，总线上的电压信号可以是在时间上连续的多个离散采样值。
在本申请的实施例中，通过对总线中的电压信号进行检测，以得到总线中的电压信号所对应的数据模型，并将该数据模型与存储的数据模型库中的模型进行比对，在比对一致的情况下，输出比对一致的数据模型中的数据信息(即本申请中的目标数据模型中的数据信息)。
具体地，通过对获取总线上采集的电压信息进行电压比对，电压上升沿斜率、电压下降沿斜率的斜率比对实现了对电压数据的筛选，并通过时间对比的方式实现了对采集得到的数据的信号还原，在此过程中，采用模型对比的方式对总线上的电压信号进行识别，减少了因空调以及其他通信系统中的电感、电容、电阻以及信号反射等受到干扰时，导致的检测得到 的信号数据异常。
在其中一个实施例中，数据模型库存储有数据模型。
通常情况下，通信协议中的一帧数据包括十几到几十个字节，其中，每个字节有10位数据，一般来说，一个字节包括起始位“0”和终止位“1”以及位于起始位“0”和终止位“1”之间的8位数据，而这8位数据是用于传输数据，基于此，数据模型库中的数据模型是根据10位数据建立的数据模型，在每位数据可以是“1”，也可以是“0”的情况下，需要构建2 8＝256个数据模型，并将其进行保存，举例来说，“1111111100”为一个通信数据模型，用十六进制表示为一个字节“FE”，其中第一个“0”为起始位，最后一个“1”为终止位，再比如“1101010100”十六进制表示为一个字节“aa”。通过构建上述数据模型，以便在得到处理后的电压信号时，可以将其与数据模型库中的数据模型进行比对，进而得到如“FE”或“aa”的数据信息。
考虑到数据模型需要占据较大的存储空间，同时，模型对比也需要较大的数据处理量，可以将8为数据划分成4+4两个部分，即前4位数据作为一个模型进行保存，后4位数据作为一个数据进行保存，此时，前4位数据仅需要2 4＝16个模型就可以完全表示，同理，后4位也需要16个模型来进行表示，在这种情况下，数据模型库中的模型仅需32个。在这种方案中，可以有效降低了模型的存储空间以及需要模型比对的数据量。
实施例二
在该实施例中，具体限定了判断电压信号是否满足空调的供电电压以及总线上的基准电压的比对条件的内容。
通常情况下，空调会通过一个通信芯片与总线连接，以实现总线上的信号的获取，而该芯片在使用时，芯片所采集的采样电压值会小于其供电电压，为了减少因总线上的电压信号对应的电压值过高，如超过其供电电压，致使空调无法对其进行采集以及还原这种情况的出现，本申请的实施例中，在进行电压比对时，限定任一采样电压值不超过供电电压，以便可以准确地对总线上的电压信号进行矫正，降低输出错误信号的几率。
此外，由于本申请的实施例需要进一步判断对电压上升沿斜率和电压 下降沿斜率是否满足斜率比对条件，若采集得到的电压信号所对应的电压值过低，则会对还原的精度产生影响，更有甚者，致使信号无法矫正。
为了解决上述问题，本申请的实施例具体限定了任一采样电压值与基准电压之间的差值要足够大，如大于预设阈值，以确保才采样电压值足够大，进而确保了还原的精度。
在上述任一实施例中，预设阈值可以根据实际需要进行设定，举例来说，如图7所示，在通信芯片的供电电压为3.3伏特时，采样电压值U2和U3不能超过3.3伏特，预设阈值的取值可以是0.5伏特，此时基准电压U0不能超过2.5伏特。
在上述任一实施例中，若电压信号不满足空调的供电电压、总线上的基准电压的比对条件时，输出错误数据模型，以提醒用户进行处理。
实施例三
在本申请的一个实施例中，具体限定了判断电压上升沿斜率和电压下降沿斜率是否满足斜率比对条件的内容。
具体地，如图2所示，判断电压上升沿斜率和电压下降沿斜率是否满足斜率比对条件的内容包括：
步骤202，取电压上升沿斜率的幅值，记作第一幅值；
步骤204，取电压下降沿斜率的幅值，记作第二幅值；
步骤206，计算第一幅值和第二幅值的比值；
步骤208，若该比值处于0.5至2之间，认为电压上升沿斜率和电压下降沿斜率符合斜率比对条件。
通过将确定的第一幅值和第二幅值进行比较，以便确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，对于差异较大的情况，认为电压信号不满足斜率比对条件，此时，输出错误数据模型，以提醒用户进行处理。
具体地，为了便于对电压信号是否满足斜率比对条件进行量化处理，本申请的实施例通过比较斜率的幅值的大小关系来确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，具体地，在第一幅值和第二幅值之间相差不超过一半的情况下，认为电压上升沿的波形和电压下降沿的波 形之间的差异较小，即满足斜率比对条件，考虑到第一幅值可以大于第二幅值，也可以小于第二幅值，若单独划分比较情况，则需要处理的数据较多。
为了减少数据处理的量，本申请的实施例通过确定第一幅值与第二幅值之间的比值的波动范围来量化第一幅值和第二幅值之间相差不超过一半这一判断条件，具体地，该比值需要大于0.5、且小于2，在此过程中，在对电压上升沿的波形和电压下降沿的波形之间的差异的过程中，仅需判断该比值是否大于0.5且小于2即可实现该差异的判定，降低了比对难度。
实施例四
在本申请的一个实施例中，提出了一种电压上升沿斜率以及电压下降沿斜率的确定过程，具体地，如图3所示，包括：
步骤302，在总线的采样电压值大于基准电压的情况下，记录第一电压值；
步骤304，在总线的采样电压值大于基准电压、且持续时长大于或等于第一预设时长，记录第二电压值；
步骤306，计算第二电压值与第一电压值的比值，并将该比值作为电压上升沿斜率。
对于电压下升沿斜率，查找以总线的采样电压值为最大电压值所对应的时刻作为开始时刻，第一预设时长后记录的采样电压值为第三电压值；计算最大电压值与第三电压值的比值，并将该比值作为电压下降沿斜率。
在该实施例中，通常情况下，空调是周期性在总线上采集数据，若在采集得到的电压值并确定的电压差值之后，将计算其与电压差值所对应的时间的比值，以得到对应的斜率，考虑到本申请的实施例是通过比较第一幅值与第二幅值之间的比值大小来确定是否满足斜率比对条件，在电压差值所对应的时间是相同的情况下，可以将第二电压值和第一电压值的比值看作电压上升沿斜率，同理，将最大电压值和第三电压值的比值看作电压下降沿斜率，以此来降低空调所需要处理的数据量。
具体地，如图7所示，基准电压为U0，在采样电压值大于基准电压U0时，记录第一电压值U1，在第一预设时长t后，记录第二电压值U2， 采样电压值为最大电压值U3，在最大电压值U3的第一预设时长t后，记录第三电压值U4，计算U2与U1的比值，记作λ1，计算U3与U4的比值，记作λ2，基于λ1与λ2相差不超过一半，认为符合斜率比对条件。
在其中一个实例中，如图8所示，具体地，基准电压为U0，在采样电压值大于基准电压U0时，记录第一电压值U1，在t/2后，即第一预设时长t的一半后，记录第四电压值U1-2，再经过t/2后，即第一预设时长t的一半后，记录第二电压值U2，采样电压值为最大电压值U3，在最大电压值U3后t/2时，即第一预设时长t的一半后，记录第五电压值U3-2，再经过t/2后，即第一预设时长t的一半后，记录第三电压值U3，计算U1-2与U1的比值，记作μ1，计算U2与U1-2的比值，记作μ3，计算U3与U3-2的比值，记作μ3，计算U3-2与U4的比值，记作μ4，若μ1与μ4相差不超过一半，且μ2与μ3相差不超过一半认为符合斜率比对条件。
实施例五
在该实施例中，具体限定了如何对电压信号进行时间对比，并得到处理后的电压信号的内容。
二进制数据是机器能够识别到的机器语言，即数据“1”和数据“0”，在本申请的实施例中，二进制数据中的第一个数码可以是数据“1”和数据“0”中的任意一个，对应的二进制数据中的第二个数码是除第一个数码的另一个数码，如在一种情况下，在第一个数码是数据“1”时，第二个数码是数据“0”，在另一种情况下在第一个数码是数据“0”时，第二个数码是数据“1”，在本申请的实施例中，选取第一个数码是数据“0”时，第二个数码是数据“1”。
空调与总线连接，通过电流传输的方式进行数据传输，比如总线上的其它通信设备要发送数据0，就从总线上拉一个恒定的电流M，发送数据1就往总线上拉一个恒定的电流N，N可以为0，只需要在电源上串一个采样电阻，总线上的其它通信设备拉的电流就会通过这个采样电阻，并在采样电阻上形成电压，通过采集这个电阻上电压的信号得到其它通信设备所传输的数据。
在该方案中，通过对电压信号进行时间对比，以便确定电压信号中包 含“1”或“0”的个数，如单独一个“1”，两个“1”。
图4示出了具体限定了如何对电压信号进行时间对比，并得到处理后的电压信号的内容。如图4所示：
步骤402，以采样电压值大于基准电压所对应的时刻作为计时开始时刻，记录第二预设时长后的第一时刻；
步骤404，以总线的采样电压值为最大电压值所对应的时刻作为开始计时时刻，记录第二预设时长后的第二时刻；
步骤406，确定第一时刻和第二时刻之间的第一时长；
步骤408，根据第一时长与第一个数码对应的时长确定第一个数码的个数；
步骤410，以总线的采样电压值再次大于基准电压所对应的时刻作为开始计时时刻，记录第二预设时长后的第三时刻；
步骤412，确定第三时刻和第二时刻之间的第二时长；
步骤414，根据第二时长与第二个数码对应的时长确定第二个数码的个数；
步骤416，根据第一个数码的个数、第二个数码的个数、第一个数码和第二个数码确定处理后的电压信号。
通常情况下，确定总线上电压信号的方式是根据总线上高电平的持续时间或低电平的持续时间来确定二进制数据中的第一个数码和第二个数码的个数，由于总线上存在信号干扰，空调采集得到的电压波动较大，精度较低。
为了解决上述问题，本申请的实施例采用时间对比的方式来确定二进制数据中的第一个数码和第二个数码的个数，并根据第一个数码的个数和第二个数码的个数对电压信号进行数据还原，在此过程中，减少了上述情况对读取信号的影响，确保了信号的可信度。
在上述任一实施例中，在第一时长与M个第一个数码对应的时长的差值小于或等于设定值，确定第一时长对应M个连续的第一个数码；在第二时长与N个第二个数码对应的时长的差值小于或等于设定值，确定第二时长对应N个连续的第二个数码，其中，M，N为自然数。
在该实施例中，考虑到由于总线过长、或与总线连接的电容或者如与总线连接的采样电阻的影响，总线上的电压信号的长度会发生变化，为了消除该影响，给出第一时长与M个第一个数码对应的时长之间的波动区间，具体地，通过计算第一时长与M个第一个数码对应的时长的差值，并将该差值与设定值进行比较，以便判断该波动区间是否超出设定值。若不超过设定值时，认定第一时长对应M个连续的第一个数码，其中，可以理解的是，即第一时刻至第二时刻之间的电压信号对应M个连续的第一个数码，同理，第二时刻至第三时刻之间的电压信号对应N个连续的第二个数码，在上述过程中，实现了对采集得到的电压信号的还原，以便得到处理后的电压信号。
在上述任一实施例中，空调通信的控制方法还包括：获取空调的波特率和总线上的实际通信时间；以及根据波特率和实际通信时间确定第一个数码对应的时长以及第二个数码对应的时长。
在该实施例中，考虑到空调进行通信的波特率不同，第一个数码对应的时长以及第二个数码对应的时长也会不同，为了确保目标数据模型的准确性，需要对第一个数码对应的时长以及第二个数码对应的时长进行标定，根据空调的波特率以及总线上的实际通信时间来确定第一个数码对应的时长以及第二个数码对应的时长。
在上述任一实施例中，实际通信时间即总线上的理论通信时间与第一等待时间、第二等待时间的差值，其中，理论通信时间可以理解为在总线上的电压值大于或等于基准电压的时长，第一等待时长为总线上的电压值大于基准电压的时长为第一等待时间之后，才开始进行获取总线上的采样电压值，同理，第二等待时间为不进行采样的时间，其对应理论通信时间的尾部。
在其中一个实施例中，第一等待时间、第二等待时间属于不对总线上的电压信号进行采样的时间，其具体数值可以预先进行设定。
举例来说，如图9所示，在波特率以及实际通信时间确定下来的情况下，第一个数码以及第二个数码的时长也确定下来了，即单个bit的时间也固定下来了。
在第一时长T1确定下来之后，计算第一时长T1与固定时间T的差值，并将该差值与设定值进行比较，其中，设定值可以取值0.5，如第一时长T1与固定时间T的差值小于0.5，认为固定时间T与第一时长T1相等，认为空调接收到一个“0”，同理，第二时长T2与固定时间T的差值，小于0.5，认为固定时间T与第二时长T2相等，认为空调接收到一个“1”。
以同样的方式，确定第三时长T3，其中，第三时长T3与2个固定时间T的差值小于0.5，认为空调接收到两个“0”，依次类推，确定第N个时长Tn与n个固定时间T的差值小于0.5，认为空调接收到一个“0”。
实施例六
在本申请的一个实施例中，如图5所示，提出了一种空调通信的控制装置500，其中，空调通信的控制装置500包括：获取单元502、确定单元504以及输出单元506，其中，空调与总线连接，并通过总线进行数据通信。其中，获取单元502，用于获取总线上的电压信号；确定单元504，用于在电压信号符合空调的供电电压以总线上的基准电压的比对条件的情况下，确定电压信号中的电压上升沿斜率以及电压下降沿斜率；在电压上升沿斜率和电压下降沿斜率符合斜率比对条件的情况下，对电压信号进行时间对比，得到处理后的电压信号；以及确定数据模型库中与处理后的电压信号一致的目标数据模型；输出单元506，用于输出目标数据模型对应的数据信息。
本申请的实施例提出了一种空调通信的控制装置500，其具体包括获取单元502、确定单元504以及输出单元506。其中，通过对总线中的电压信号进行检测，以得到总线中的电压信号所对应的数据模型，并将该数据模型与存储的数据模型库中的模型进行比对，在比对一致的情况下，输出比对一致的数据模型中的数据信息(即本申请中的目标数据模型中的数据信息)。
具体地，通过对获取总线上采集的电压信息进行电压比对，电压上升沿斜率、电压下降沿斜率的斜率比对实现了对电压数据的筛选，并通过时间对比的方式实现了对采集得到的数据的信号还原，在此过程中，采用模型对比的方式对总线上的电压信号进行识别，减少了因空调以及其他通信 系统中的电感、电容、电阻以及信号反射等受到干扰时，导致的检测得到的信号数据异常。
在其中一个实施例中，数据模型库存储有数据模型。
通常情况下，通信协议中的一帧数据包括十几到几十个字节，其中，每个字节有10位数据，一般来说，一个字节包括起始位“0”和终止位“1”以及位于起始位“0”和终止位“1”之间的8位数据，而这8位数据是用于传输数据，基于此，数据模型库中的数据模型是根据10位数据建立的数据模型，在每位数据可以是“1”，也可以是“0”的情况下，需要构建28＝256个数据模型，并将其进行保存，举例来说，“1111111100”为一个通信数据模型，用十六进制表示为一个字节“FE”，其中第一个“0”为起始位，最后一个“1”为终止位，再比如“1101010100”十六进制表示为一个字节“aa”。通过构建上述数据模型，以便在得到处理后的电压信号时，可以将其与数据模型库中的数据模型进行比对，进而得到如“FE”或“aa”的数据信息。
考虑到数据模型需要占据较大的存储空间，同时，模型对比也需要较大的数据处理量，可以将8为数据划分成4+4两个部分，即前4位数据作为一个模型进行保存，后4位数据作为一个数据进行保存，此时，前4位数据仅需要24＝16个模型就可以完全表示，同理，后4位也需要16个模型来进行表示，在这种情况下，数据模型库中的模型仅需32个。在这种方案中，可以有效降低了模型的存储空间以及需要模型比对的数据量。
实施例七
在该实施例中，具体限定了判断电压信号是否满足空调的供电电压以及总线上的基准电压的比对条件的内容。
通常情况下，空调会通过一个通信芯片与总线连接，以实现总线上的信号的获取，而该芯片在使用时，芯片所采集的采样电压值会小于其供电电压，为了减少因总线上的电压信号对应的电压值过高，如超过其供电电压，致使空调无法对其进行采集以及还原这种情况的出现，本申请的实施例中，在进行电压比对时，确定单元504具体用于限定任一采样电压值不超过供电电压，以便可以准确地对总线上的电压信号进行矫正，降低输出 错误信号的几率。
此外，由于本申请的实施例需要进一步判断对电压上升沿斜率和电压下降沿斜率是否满足斜率比对条件，若采集得到的电压信号所对应的电压值过低，则会对还原的精度产生影响，更有甚者，致使信号无法矫正。
为了解决上述问题，确定单元504具体用于限定了任一采样电压值与基准电压之间的差值要足够大，如大于预设阈值，以确保才采样电压值足够大，进而确保了还原的精度。
在上述任一实施例中，预设阈值可以根据实际需要进行设定，举例来说，在通信芯片的供电电压为3.3伏特时，预设阈值的取值可以是0.5伏特，此时基准电压不能超过2.5伏特。
在上述任一实施例中，若电压信号不满足空调的供电电压、总线上的基准电压的比对条件时，输出错误数据模型，以提醒用户进行处理。
实施例八
在该实施例中，具体限定了判断电压上升沿斜率和电压下降沿斜率是否满足斜率比对条件的内容。
具体地，确定单元504用于：取电压上升沿斜率的幅值，记作第一幅值；取电压下降沿斜率的幅值，记作第二幅值；计算第一幅值和第二幅值的比值；若该比值处于0.5至2之间，认为电压上升沿斜率和电压下降沿斜率符合斜率比对条件。
通过将确定的第一幅值和第二幅值进行比较，以便确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，对于差异较大的情况，认为电压信号不满足斜率比对条件，此时，输出错误数据模型，以提醒用户进行处理。
具体地，为了便于对电压信号是否满足斜率比对条件进行量化处理，本申请的实施例通过比较斜率的幅值的大小关系来确定电压上升沿的波形和电压下降沿的波形是否存在较大差异，具体地，在第一幅值和第二幅值之间相差不超过一半的情况下，认为电压上升沿的波形和电压下降沿的波形之间的差异较小，即满足斜率比对条件，考虑到第一幅值可以大于第二幅值，也可以小于第二幅值，若单独划分比较情况，则需要处理的数据较 多。
为了减少数据处理的量，本申请的实施例通过确定第一幅值与第二幅值之间的比值的波动范围来量化第一幅值和第二幅值之间相差不超过一半这一判断条件，具体地，该比值需要大于0.5、且小于2，在此过程中，在对电压上升沿的波形和电压下降沿的波形之间的差异的过程中，仅需判断该比值是否大于0.5且小于2即可实现该差异的判定，降低了比对难度。
实施例九
在该实施例中，确定单元504具体用于确定电压上升沿斜率以及电压下降沿斜率，具体地，在总线的采样电压值大于基准电压的情况下，记录第一电压值；在总线的采样电压值大于基准电压、且持续时长大于或等于第一预设时长，记录第二电压值；以及计算第二电压值与第一电压值的比值，并将该比值作为电压上升沿斜率。
对于电压下升沿斜率，查找以总线的采样电压值为最大电压值所对应的时刻作为开始时刻，第一预设时长后记录的采样电压值为第三电压值；计算最大电压值与第三电压值的比值，并将该比值作为电压下降沿斜率。
在该实施例中，通常情况下，空调是周期性在总线上采集数据，若在采集得到的电压值并确定的电压差值之后，将计算其与电压差值所对应的时间的比值，以得到对应的斜率，考虑到本申请的实施例是通过比较第一幅值与第二幅值之间的比值大小来确定是否满足斜率比对条件，在电压差值所对应的时间是相同的情况下，可以将第二电压值和第一电压值的比值看作电压上升沿斜率，同理，将最大电压值和第三电压值的比值看作电压下降沿斜率，以此来降低空调所需要处理的数据量。
具体地，如图7所示，基准电压为U0，在采样电压值大于基准电压U0时，记录第一电压值U1，在第一预设时长t后，记录第二电压值U2，采样电压值为最大电压值U3，在最大电压值U3的第一预设时长t后，记录第三电压值U4，计算U2与U1的比值，记作λ1，计算U3与U4的比值，记作λ2，基于λ1与λ2相差不超过一半，认为符合斜率比对条件。
在其中一个实例中，如图8所示，具体地，基准电压为U0，在采样电压值大于基准电压U0时，记录第一电压值U1，在t/2后，即第一预设时 长t的一半后，记录第四电压值U1-2，再经过t/2后，即第一预设时长t的一半后，记录第二电压值U2，采样电压值为最大电压值U3，在最大电压值U3后t/2时，即第一预设时长t的一半后，记录第五电压值U3-2，再经过t/2后，即第一预设时长t的一半后，记录第三电压值U3，计算U1-2与U1的比值，记作μ1，计算U2与U1-2的比值，记作μ3，计算U3与U3-2的比值，记作μ3，计算U3-2与U4的比值，记作μ4，若μ1与μ4相差不超过一半，且μ2与μ3相差不超过一半认为符合斜率比对条件。

具体地，确定单元504用于：以采样电压值大于基准电压所对应的时刻作为计时开始时刻，记录第二预设时长后的第一时刻；以总线的采样电压值为最大电压值所对应的时刻作为开始计时时刻，记录第二预设时长后的第二时刻；确定第一时刻和第二时刻之间的第一时长；根据第一时长与第一个数码对应的时长确定第一个数码的个数；以总线的采样电压值再次大于基准电压所对应的时刻作为开始计时时刻，记录第二预设时长后的第三时刻；确定第三时刻和第二时刻之间的第二时长；根据第二时长与第二个数码对应的时长确定第二个数码的个数；根据第一个数码的个数、第二个数码的个数、第一个数码和第二个数码确定处理后的电压信号。
通常情况下，确定总线上电压信号的方式是根据总线上高电平的持续时间或低电平的持续时间来确定二进制数据中的第一个数码和第二个数码的个数，由于总线上存在信号干扰，空调采集得到的电压波动较大，精度 较低。
为了解决上述问题，本申请的实施例采用时间对比的方式来确定二进制数据中的第一个数码和第二个数码的个数，并根据第一个数码的个数和第二个数码的个数对电压信号进行数据还原，在此过程中，减少了上述情况对读取信号的影响，确保了信号的可信度。

在上述任一实施例中，空调通信的控制方法还包括：获取空调的波特率和总线上的实际通信时间；以及根据波特率和实际通信时间确定第一个数码对应的时长以及第二个数码对应的时长。
在该实施例中，考虑到空调进行通信的波特率不同，第一个数码对应的时长以及第二个数码对应的时长也会不同，为了确保目标数据模型的准确性，需要对第一个数码对应的时长以及第二个数码对应的时长进行标定，根据空调的波特率以及总线上的实际通信时间来确定第一个数码对应的时长以及第二个数码对应的时长。
