Description

空调器防雷电控制方法，控制装置和空调器室外机 技术领域
本发明属于空气调节技术领域，尤其涉及一种空调器防雷电控制方法，一种空调器防雷电控制装置以及一种空调器室外机。
 背景技术
在一般的高层住宅中，分体式空调器仍占有较大比例。对于高层建筑的防雷通常集中在对建筑物的防雷设计上，要求要做好防侧击雷保护，外墙上所有金属物均与避雷带可靠连接，避雷带再与引下线可靠连接等等。雷电的产生主要是云层间或者云和大地之间以及云和空气间的电位差达到一定程度时，所发生的猛烈放电现象。雷击通常包括直击雷和感应雷。对于直击雷，当建筑物外墙上空调器室外机等金属物所处的高度超出雷闪模型滚球半径的高度时，金属物就容易遭受雷电侧击。或者，当雷电流超过接闪器所保护的最小雷电流幅值时，也容易将空调击穿，同时雷电流还会沿着电源线传输，造成屋内其它电子设备的破坏。对于感应雷，则是由于雷云之间或雷云对地之间的放点会在附近的架空线路、金属物或类似的传导体上产生感应电压，该电压再通过传导体传送至设备，间接摧毁微电子设备。尤其是当雷电流变化梯度达到50kA/μs,放电电流达到300-400kA时，会产生强大的交变磁场，在空调感应环路中产生的感应电压将远远超过空调器安全承受电压，将其击穿造成致命的破坏。
 技术问题
现有技术中高层住宅的防雷解决方案主要还是集中在对建筑物的改进方面，例如增加接闪器、引下线、接地网和避雷器等等。但实际上，绝大多数建筑物外墙上的空调器室外机及其金属支架均未与建筑物的防雷装置连接。尤其是空调器的选购通常是在建筑物交工验收后并由用户自行安装的，其位置、外形、尺寸均由使用者自己选定，对应的位置可能并没有设计供空调器室外机及其金属固定支架防侧击雷的连接预埋点。因此，在雷电发生时，使用空调器还是存在比较大的安全风险，可能会发生安全事故。
 技术解决方案
本发明针对现有技术中绝大多数建筑物外墙上的空调器室外机及其金属支架均未与建筑物的防雷装置连接，尤其是空调器的选购通常是在建筑物交工验收后并由用户自行安装的，其位置、外形、尺寸均由使用者自己选定，对应安装位置没有设计供空调器室外机及其金属固定支架防侧击雷的连接预埋点，导致在雷电发生时，空调器的使用存在安全风险的问题，设计并提供一种空调器防雷电控制方法。
为实现上述发明目的，本发明采用下述技术方案予以实现。

针对现有技术中绝大多数建筑物外墙上的空调器室外机及其金属支架均未与建筑物的防雷装置连接，尤其是空调器的选购通常是在建筑物交工验收后并由用户自行安装的，其位置、外形、尺寸均由使用者自己选定，对应安装位置没有设计供空调器室外机及其金属固定支架防侧击雷的连接预埋点，导致在雷电发生时，空调器的使用存在安全风险的问题，设计并提供一种空调器防雷电控制方法，通过在空调器室外机一侧增加监测手段，在满足特定环境条件时自动启动空调器保护模式，保护设备和人身安全。具体来说，参见图1所示，这种空调器防雷电控制方法主要包括以下步骤。
S10，按照设定检测周期间隔启动雷电检测模式。
S20，在雷电检测模式下，至少采样空调器室外机所在位置的实时环境声音强度，并判断两个实时声音强度检测值是否满足增强趋势。
S30，在雷电检测模式下，启动瞬时检测周期，并在每一个瞬时检测周期内至少采样空调器室外机所在位置的实时环境光照强度，并判断两个实时环境光照强度之差是否大于等于瞬间光照强度变化阈值。
S40，如果实时声音强度检测值满足增强趋势且实时环境光照强度之差大于等于瞬间光照强度变化阈值，则启动空调器保护模式。
雷电检测模式下，实时环境声音强度的检测优选由设置在空调器室外机中的分贝测试仪实现。为了与室外环境中的正常噪音区别，设置分贝测试仪自动滤除低于设定噪音等级的采样值。例如，分贝测试仪仅在所采集到的噪声级达到90分贝时，才认为采样得到一个空调器室外机所在位置的实时环境声音强度。在雷电检测模式下，如果分贝测试仪采样到至少两次空调器室外机所在位置的实时环境声音强度，并判断两个实时声音强度检测值满足增强趋势，则向空调器室外机主控板输出信号，即得到判断当前雷电状态的第一路检测信号。
同样在雷电检测模式下，启动瞬时检测周期。瞬时检测周期主要用于检测闪电。瞬时检测周期设定为1至2秒。进一步在瞬时检测周期的起始时刻和终止时刻分别采样一次空调器室外机所在位置的实时环境光照强度，并判断两个实时环境光照强度之差是否大于等于瞬间光照强度变化阈值。采样空调器室外机所在位置的实时环境光照强度优选通过光照探测器或者流明测试仪实现，瞬间光照强度变化阈值在实验条件下获得。如果光照探测器或者流明测试仪采样到两个实时环境光照强度之差大于等于瞬间光照强度变化阈值，则向空调器室外机主控板输出信号，即得到判断当前雷电状态的第二路检测信号。
空调器室外机主控板在得到实时声音强度检测值满足增强趋势且实时环境光照强度之差大于等于瞬间光照强度变化阈值的判断结果后，启动空调器保护模式。具体来说，优选在空调器的总电源回路中串联一路单独的继电器的常闭触点，如果在雷电检测模式下，确定了雷电使用状态，则由空调器室外机主控板输出驱动信号，驱动常闭触点断开。常闭触点优选与独立于空调器控制面板的防雷电按钮联动，只有用户再次按下防雷电按钮，空调器才可以恢复正常供电。优选的，在数据处理能力满足的条件下，优选设定多次采样实时环境声音强度以及多个实时环境光照强度，并判断多个实时声音强度检测值是否满足增强趋势，以及是否有多组相邻的实时环境光照强度之差大于等于瞬间光照强度变化阈值。
通过对实时环境声音强度以及实时环境光照强度的检测，可以识别出空调器室外机所处环境的雷电情况，及时启动空调器保护模式，对空调器进行有效保护。
强制切断空调器电源回路会影响用户的实际体验，因此，在本发明所提供的控制方法中，需要最大程度的避免出现误判。结合气象常识，虽然雷电通常分为热雷电、锋雷电和地形雷电3大类，但在城市环境中，最常见的雷电类型为热雷电。其中，热雷电必须具备以下条件：1，空气非常潮湿，空气中的水蒸气接近饱和；2. 环境中无风或小风，气流变化不大；3. 温度快速升高。这三个条件也与用户使用空调器的环境条件高度吻合，是最需要进行防护的雷电类型。针对这一使用特点，特别设计了通过以下步骤确定所述设定检测周期。
参见图2所示：步骤S51，采样空调器外机所在位置的实时环境湿度。实时环境湿度通过设置在空调器室外机中的湿度传感器实现，湿度传感器连接室外机主控芯片。
步骤 S52，判断所述实时环境湿度是否小于第一设定湿度阈值；如果实时环境湿度小于第一设定湿度阈值，则保持不启动所述雷电检测模式。当实时环境湿度小于第一设定湿度阈值时，此时空气非常干燥，在未来的一段时间，极小的可能性会产生雷电，此种状态下需重点保障用户的正常使用。因此，保持不启动雷电检测模式。
步骤S53，如果实时环境湿度大于等于第一设定湿度阈值，则判断所述实时环境湿度是否小于第二设定湿度阈值；如果实时环境湿度小于第二设定湿度阈值，则按照第一设定检测周期间隔启动雷电检测模式。当实时环境湿度大于等于第一设定湿度阈值且小于第二设定湿度阈值时，需要对未来一段时间的气象条件进行监测，因此，设定按照第一设定检测周期间隔启动雷电检测模式，第一设定检测周期相对较长，例如可以设定为3-5小时。第一设定检测周期还优选在实时室外环境温度和实时室外风机的实时逆风风速两个条件的约束下进行精校。具体来说，当实时环境湿度大于等于第一设定湿度阈值且小于第二设定湿度阈值时，判断室外环境温度是否大于等于室外环境温度阈值，室外风机的实时逆风风速是否小于等于逆风风速阈值，如果室外环境温度大于等于室外环境温度阈值且室外风机的实时逆风风速小于等于逆风风速阈值，则满足实时湿度较低，但温度较高，风速较小的条件，在此种状态下，优选通过精校自动缩短第一设定检测周期。例如若第一设定检测周期为3小时，在实外环境温度大于等于室外环境温度阈值且室外风机的实时逆风风速小于等于逆风风速阈值的约束条件下，自动将第一设定检测周期精校缩短为2小时，对预警情况进行更高频次的关注。其中，第一设定湿度阈值为30%，第二设定湿度阈值为50%。
步骤S54，如果实时环境湿度大于等于第二设定湿度阈值，则判断所述实时环境湿度是否小于第三设定湿度阈值；如果实时环境湿度小于第三设定湿度阈值，则按照第二设定检测周期间隔启动雷电检测模式。此种状态下，湿度处于更高的状态，进一步缩短检测周期，第二设定周期优选设定为1小时。第三设定湿度阈值为70%。
步骤S55， 如果实时环境湿度大于等于第三设定湿度阈值，则判断所述实时环境湿度是否小于第四设定湿度阈值；如果实时环境湿度小于第四设定湿度阈值，则按照第三设定检测周期间隔启动雷电检测模式。此种状态下，湿度处于更高的状态，进一步缩短检测周期，第三设定检测周期优选设定为0.5小时，第四设定湿度阈值为90%。
步骤S56，如果实时环境湿度大于等于第四设定湿度阈值，则按照第四设定检测周期间隔启动雷电检测模式。此时湿度已经非常高，第四设定检测周期优选设定为0.3小时。
将形成热雷电的自然条件与设定检测周期的实际时长进行结合，可以有效地提高雷电检测模式的检测精度，剔除其它外界条件的影响，降低误判率，提高用户的使用体验。
更为优选的，还可以通过实时环境声音强度大致确定声源距离，当雷电发生的位置较远时，造成事故的风险小，当雷电发生的位置较近时，造成事故的风险大。基于这一原则，特别设计了以下步骤，如果两个实时声音强度检测值满足增强趋势且两个实时环境光照强度之差大于等于瞬间光照强度变化阈值，则进一步判断最后一个实时环境声音强度是否大于等于第一设定声音强度保护阈值，如果大于等于第一设定声音强度保护阈值，说明此时声源距离较近，则在空调器保护模式下，切断空调器电源，例如控制继电器的常闭触点断开。第一设定声音强度保护阈值在实验条件下获得，例如可以设定为120分贝。如果最后一个实时环境声音强度小于第一设定声音强度保护阈值， 则判断最后一个实时环境声音强度是否大于等于第二设定声音强度保护阈值，如果大于等于第二设定声音强度保护阈值，说明此时声源距离相对较远，则在空调器保护模式下，控制空调器进入待机状态，控制压缩机，室外风机等主要部件停机，用户可以在短时雷电结束后通过普通操作恢复供电。所述第二设定声音强度保护阈值小于所述第一设定声音强度保护阈值，例如可以设定为105分贝。
出于降低误判率的要求，还特别设计了，如果两个实时声音强度检测值满足增强趋势且两个实时环境光照强度之差大于等于瞬间光照强度变化阈值，则判断最后一个实时环境声音强度是否大于等于第一设定声音强度保护阈值，如果大于等于第一设定声音强度保护阈值，则按照修正检测周期再次间隔启动雷电检测模式，并再次判断两个实时声音强度检测值是否满足增强趋势且两个实时环境光照强度之差是否大于等于瞬间光照强度变化阈值，如果再次判断两个实时声音强度检测值满足增强趋势且两个实时环境光照强度之差大于等于瞬间光照强度变化阈值，则进一步再次判断最后一个实时环境声音强度是否大于等于第一设定声音强度保护阈值，如果大于等于第一设定声音强度保护阈值，则启动空调器保护模式，控制空调器进入待机状态。修正检测周期可以设定为1-5分钟。即通过冗余检测提高检测精度，避免出现误判终止用户使用的情况。
同样的，如果两个实时声音强度检测值满足增强趋势且两个实时环境光照强度之差大于等于瞬间光照强度变化阈值，且最后一个实时环境声音强度小于第一设定声音强度保护阈值，则判断最后一个实时环境声音强度是否大于等于第二设定声音强度保护阈值，如果大于等于第二设定声音强度保护阈值，则按照实时环境湿度对应的修正检测周期再次间隔启动雷电检测模式，并再次判断两个实时声音强度检测值是否满足增强趋势且两个实时环境光照强度之差是否大于等于瞬间光照强度变化阈值，如果再次判断两个实时声音强度检测值满足增强趋势且两个实时环境光照强度之差大于等于瞬间光照强度变化阈值，则再次判断最后一个实时环境声音强度是否大于等于第二设定声音强度保护阈值且小于第一设定声音强度保护阈值，如果大于等于第二设定声音强度保护阈值且小于第一设定声音强度保护阈值，则在空调器保护模式下，切断空调器电源。
