具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
实施例1
下面结合附图对本发明提供的空调器压缩机电加热控制方法进行说明。
本发明提供的空调器压缩机电加热控制方法可以应用在家用空调器上，可以在商场等商用空调器或者船用空调设备上实现。图1示出本方法的一种可选的流程图，如图1所示，该空调器压缩机电加热控制方法可以包括以下步骤：
S102，监听获知空调器压缩机停止运行时间超过第三预设时间阈值，获取天气预报数据；
优选地，在监听获知空调器压缩机停止运行时间超过第三预设时间阈值之前，还包括：每隔第一预设时间发送第一请求信息至对应的数据库服务器，以获得未来第二预设时间内空调器所在区域的天气预报数据；接收数据库服务器返回的天气预报数据，并存储至空调器内置的数据库。
具体来说，通过预先设置，空调器内置的通讯模块每间隔第一预设时间都会发送第一请求信息至数据库服务器。优选地，通过空调器内置的通讯模块定位空调器所在区域以确定空调器的位置信息；获取预设的第二预设时间阈值；生成包含有空调器的位置信息和第二预设时间阈值的第一请求信息，并发送至数据库服务器以获得未来第二预设时间阈值内空调器所在区域的天气预报数据，其中，数据库服务器解析第一请求信息，通过自身网络接口访问天气平台获得第一请求信息对应的天气预报数据，并返回至空调器的通讯模块。
S104，根据天气预报数据生成控制策略以控制空调器压缩机电加热的启停。
具体实现时，在空调器内置的数据库获取的天气预报数据中，筛选出当前时间之后第四预设时间阈值内的天气预报数据；分析确定第四预设时间阈值内的天气预报数据中温度值随时间变化趋势，在变化趋势为增高的时间内控制空调器压缩机电加热开启，在变化趋势为非增高的时间内控制空调器压缩机电加热关闭。
在本发明的一个可选的实施方式中，提供了一种简单有效的分析确定第四预设时间阈值内的天气预报数据中温度值随时间变化趋势的 方案，具体来说，将第四预设时间阈值等分为预设的n个单位时间段，分别记作F1…Fk…Fn，其中，n、k为自然数，k∈[2，n]；计算n个单位时间段F1…Fk…Fn中每一时间段内温度的平均值，分别记作t1…tk…tn；比较每一时间段内温度的平均值与该时间段的前一时间段内温度的平均值，确定第四预设时间阈值内的天气预报数据中温度值随时间变化趋势。
在进行上述比较时，可以采用下面的方案来实现，通过以下公式计算并判断：
当tk-t(k-1)＞0时，判定在Fk时间段内温度值随时间变化趋势为增高的时间；当tk-t(k-1)≤0时，判定Fk时间段内温度值随时间变化趋势为非增高的时间。
此外，当k＝n时，表征第三预设时间阈值内天气预报数据处理完毕，继续监听获知空调器压缩机停止运行时间是否超过第三预设时间阈值。
下面结合附图2对本发明的空调器压缩机电加热控制方法进行进一步的说明，以便更好的理解本发明。
S201，通讯模块每隔T＝6h发送天气预报数据请求；并且，通讯模块每隔T＝6h通过蜂窝网络定位自身位置获得其位置信息；
S202，通讯模块将S201中两个信息通过蜂窝网络发送给指定的服务器(数据库服务器)；
S203，服务器收到通讯模块发送的信息通过网络途径获得当地未来的天气预报数据；
S204，服务器将获得的天气预报数据发送到通讯模块中；
S205，通讯模块将收到的信息返回到到空调器的控制器中进行存储，将之前存储的数据进行替换；
S206，监听获知压缩机停止运行A≥1h，控制器调用存储的天气预报数据；
S207，控制器根据天气预报数据，截取压缩机停止时间T所对应的时刻开始往后T0＝6h所包含的天气预报所有数据；
S208，将截取的数据(未来T0内的数据)等分成n分，定义每等分记录为F1…Fk…Fn。将每份数据处理得出其平均值，即每等分的平 均数为：t1…tk…tn；定义k取[2,n],n至少为2；
S209，判断检测tk-t(k-1)＞0，若是，执行步骤S210，否则，执行步骤S211；
S210，预约在等分区Fk对应的时刻电加热开启；
S211，预约在等分区Fk对应的时刻电加热关闭；
S212，判断是否k＝n，若是，跳转至步骤S202，否则，跳转至步骤S209。
从以上描述中可看出，在本发明中，在空调器内部设置有用于网络通信的通讯模块，可与包含天气数据的数据库服务器连接通信，通讯模块每隔预设时间内发送请求信息至数据库服务器，请求信息中携带有时间请求信息和空调所在区域的位置请求信息，数据库服务器即可返回空调器所需的天气预报数据。空调器将数据库服务器返回的天气预报数据存储至自身的数据库中。当空调器压缩机停止运行时间超过第三预设时间阈值时，直接在自身数据库中调用所需的天气预报数据，将该天气预报数据作为空调器处于待机状态下压缩机是否需要电加热的依据。这种控制方案有效地解决了现有技术中空调器处于待机状态下压缩机仍需大量电加热导致空调压缩机待机功耗大的问题，减少空调待机状态下电加热开启时间，也减少了能耗。
