Description
本发明涉及计算机技术领域，尤其涉及一种电子烟加热温度的控制方法及装置。
电子烟是一种模仿卷烟的电子产品，有着与卷烟类似的外观和味道。而加热型电子烟是对烟草进行加热来取代燃烧，以供吸烟者进行吸食，即对烟草进行低温加热来蒸发出尼古丁以及香料，以得到与抽真烟一样的真实烟草香味和口感。也就是说，对于加热型电子烟来讲，其对应的加热温度的控制是非常重要的，因为不同的加热温度对可抽吸材料(如烟丝)进行加热的程度不一样，从而对应了不同的抽吸口感。如果加热温度过低，则可能达不到相应的效果，不能产生足够的尼古丁等，达不到相应的抽吸口感；反之，若加热温度过高，则容易导致烟草局部烤焦，产生有害物质，增加威胁吸烟者的健康的风险，同时，也降低了用户的吸烟口感，降低了用户对于电子烟产品的使用体验。
而在相关技术方案中，对于加热温度的控制，多采用温度大于目标温度时，输出功率增加，小于目标温度时，输出功率减小的办法，对于这种温度控制的方案来讲，其对应的控制效果不佳，对于温度的控制不够准确并且容易过线温度过低或过高的情况，极大的降低了用户的吸烟口感。

为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术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发明的一些实施例，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。
其中：
图1为一个实施例中一种电子烟设备的结构示意图；
图2为一个实施例中一种电子烟加热温度的控制方法的流程示意图；
图3为一个实施例中电子烟设备的加热温度获取的流程示意图；
图4为一个实施例中电子烟设备中加热温度获取的电路示意图；
图5为一个实施例中一种电子烟加热温度的控制装置的结构示意图。
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为解决传统技术中对加热型电子烟的加热温度的控制存在控制准确率不足的技术问题，在本实施例中，特提出了一种电子烟加热温度的控制方法，该方法的实现可依赖于计算机程序，该计算机程序可运行于基于冯诺依曼体系的计算机系统之上，该计算机程序可以是基于电子烟设备的加热温度控制的应用程序，例如，集成在电子烟烟杆的单片机中对加热温度进行控制的控制程序。
具体的，上述电子烟加热温度的控制方法的实现和执行基于一电子烟设备，该电子烟设备可以是加热型电子烟的电子烟烟杆，可以容纳例如烟丝等可抽吸材料，并且可以对该可抽吸材料进行加热以供用户进行抽吸。如图1所示，该电子烟设备包括加热电路，所述加热电路包括加热电阻，例如，为热敏电阻或负载电阻。并且，通过加热电路给加热电阻供电，从而使得所述加热电子发热 以给放置在所述电子烟设备中的可抽吸材料加热以供用户进行抽吸。需要说明的是，在本实施例中，加热电路的供电是通过PWM(Pulse Width Modulation，脉冲宽度调制)输出来实现的，也就是说，与加热电路连接的供电电路通过输出PWM脉冲来给加热电路供电，也就是说，加热电路的输入端与PWM输出端(即供电电路的输出端)连接。
需要说明的是，在本实施例中，不同的PWM脉宽对应了不同的输出功率，从而对加热电路的输出功率也不相同，因此，在需要对加热电路的功率进行调节的时候可以通过PWM脉宽的调节来对加热电路的功率，从而实现对加热电阻的温度的调节。
具体的，如图2所示，上述电子烟加热温度的控制方法包括如下步骤S102-S108：
步骤S102：获取所述加热电阻的当前加热温度值。
在一个具体的实施例中，因为对于加热电阻来讲，因为电阻为热敏电阻，其在不同的温度情况下，对应了不同的阻值，也就是说，电阻值与加热温度之间存在一一对应关系。因此，在本实施例中，可以通过电阻值的测量来获取加热电阻当前的电阻值。
在一个具体的实施例中，上述获取所述加热电阻的当前加热温度值的步骤还包括如图3所示的步骤S1021-S1022：
步骤S1021：检测所述加热电阻两端的当前电阻值；
步骤S1022：根据预设的电阻值与温度值之间的温阻对应关系确定与所述当前电阻值对应的温度值作为所述当前加热温度值。
也就是说，在本实施例中，温度的计算是通过对电阻的电阻值的测算来完成的，而加热电阻本身为热敏电阻，因此可以通过测量加热电阻的电阻值来获知其温度。
在一个具体的实施例中，可以通过如图4所示的电路来实现对加热电阻的电阻以及温度的测量。如图4所示，图中RL为负载(发热材料)，平时R_DET_EN端为低电压，检测负载电阻时，R_DET_EN被芯片控制为高电压，Q2导通，芯 片读取V_OUT和V_OUT_DET两处的ADC值分别为N
1、N
2，读取完毕马上R_DET_EN端为低电压关闭Q2，然后通过
计算负载电阻值，然后在根据做成负载的发热材料的温阻关系计算出对应的温度，此温度即为发热电阻当前的温度值。
在本实施例中，对加热电阻当前加热温度值进行检测的目的是为了对电子烟的加热温度进行控制，而为了提高控制精度，需要实时地或者较高频率的对当前加热温度值进行检测。例如，在一个实施例中，为了提高温度控制的有效性和精准度，按照预设的时间周期值，周期性的执行所述获取所述加热电阻的
当前加热温度值的步骤，例如，按照100mS的周期执行上述步骤S102。
步骤S104：检测所述PWM输出端当前输出的占空比大小为当前占空比值。
输出的PWM占空比决定了输出的功率，也就是说，不同的PWM占空比对于加热电路来讲对应了不同的加热功率，也即对应了不同的加热温度。因此，在当前加热温度值与预设的目标温度值之间存在差距的情况下，可以通过控制PWM占空比来控制输出功率从而来实现对于加热温度的控制。
而对于PWM占空比的控制和调节，首先需要获知当前的PWM占空比的情况，然后对PWM占空比进行调节。
在本实施例中，对于当前的PWM占空比的检测是通过对PWM输出端当前输出的PWM的占空比大小来完成的，即当前占空比值。
步骤S106：根据所述当前占空比值和所述当前加热温度值、预设的目标温度值确定目标占空比调节值。
步骤S108：根据所述目标占空比调节值对所述PWM输出端输出的PWM进行调节。
在本实施例中，对PWM占空比的调节，既需要考虑到当前加热温度值以及目标温度值之间的差值以及具体的值，还需要考虑当前的PWM占空比的大小，因此，在确定当前需要对PWM占空比调节的具体调节时，需要根据步骤S102 以及步骤S104中确定的当前占空比值以及当前加热温度值、以及预设的目标温度值来确定需要进行PWM占空比调节的目标占空比调节值。例如，目标占空比调节值可以为在本次调节中对PWM占空比进行调节的目标值。
在目标占空比调节值确定之后，即可根据目标占空比调节值对PWM输出端输出的PWM进行调节，也就是说，调节之后的PWM占空比的大小即为目标占空比调节值。
其中，需要指出的是，目标温度值为预设的最佳抽吸口感的温度值，例如，可以设置目标温度值为320度，或者用户还可以根据自己对于抽吸口感的要求，自定义设置目标温度值，例如，对于喜欢浓重口感的用户，可以设置一个比较高的目标温度值，如360度。
如下，对PWM占空比的调节的具体过程可以根据当前的占空比的大小以及当前加热温度值的具体大小、分情况进行确定。
在一个具体的实施例中，在所述当前加热温度值大于所述目标温度值、且所述第一差值超过预设的差值阈值的情况下，获取所述PWM输出端当前输出的占空比值为缓存占空比值；将所述目标占空比调节值设置为0。
也就是说，在当前占空比值D
N-1≠0，且当前加热温度值T
N-1＞T
t+T
E的情况下(其中，T
t为目标温度值，T
E为预设的差值阈值)，将目标占空比调节值设置为0，即将PWM输出清0，以便降低加热电阻的温度。
在占空比为0或者将占空比的设置为0之后，在据所述当前占空比值和所述当前加热温度值、预设的目标温度值确定目标占空比调节值的过程中，对PWM占空比进行调节的具体过程为：在所述当前占空比值为0、且所述获取到的当前加热温度值小于或等于所述目标温度值的情况下，将所述目标占空比调节值设置为所述缓存占空比值。
也就是说，在将PWM占空比清零之前，还需要将当前的PWM占空比的具体大小进行存储，以便后续在设置PWM占空比的具体值时，能确定与目标温度值较为接近的PWM占空比，提高用户的使用体验。因此，在占空比为0的情况 下，如果检测到的当前加热温度值大于或等于目标温度值，则保持PWM占空比为0的状态；如果检测到的当前加热温度值小于或等于目标温度值，则需要对PWM占空比进行调节，因此，将目标占空比调节值设置为缓存的占空比值，即为上一次对PWM占空比执行清零操作之前的存储的占空比的值。
也即，在当前占空比值D
N-1＝0，且当前加热温度值T
N-1＜T
t的情况下(其中，T
t为目标温度值)，将目标占空比调节值D
N设置为缓存的占空比值D′，即将PWM占空比调节为与缓存的占空比值D′对应的大小，以便控制电子烟的加热温度在最佳的目标温度左右。
在另一个可选的实施例中，当前加热温度值小于或等于目标温度值且占空比不为0的情况下，上述根据所述当前占空比值和所述当前加热温度值、预设的目标温度值确定目标占空比调节值的过程为：计算所述目标温度值与所述当前加热温度值之间的温度差值作为第一差值，根据预设的差值与量化值之间的对应关系，获取与所述第一差值对应的第一差值量化值，第一差值量化值为0到1之间的数值；获取上一次对PWM进行调节的过程中与所述目标温度值与获取到的加热温度值的温度差值对应的量化值作为第二差值量化值；根据所述当前占空比值和所述第一差值量化值、所述第二差值量化值确定所述目标占空比调节值。
且，其中，根据所述当前占空比值和所述第一差值量化值、所述第二差值量化值确定所述目标占空比调节值，具体为：
根据公式
D
N＝D
N-1+2E
N-E
N-1
计算所述目标占空比调节值，其中，D
N为目标占空比调节值，D
N-1为当前占空比值，E
N为第一差值量化值，E
N-1为第二差值量化值。
也就是说，在当前占空比值不为0，且当前加热温度值小于目标温度值或者没有超过目标温度一定范围(例如，比目标温度值大了不到5℃)的情况下，对PWM占空比进行调节，但是调节的幅度为当前占空比值加上两倍的差值量化 值、并减去上一次的差值量化值。其中，差值量化值为根据检测到的当前加热温度值与目标温度值之间的差值给出的一个0到1之间的量化值，例如，在差值为5℃的情况下，将差值量化值设置为2％。
需要说明的是，在本实施例中，第一差值量化值E
N代表的是本次调节(即第N次调节)中，检测到的当前加热温度值与目标温度值之间的差值所对应的差值量化值；第二差值量化值E
N-1代表的是本次调节(即第N-1次调节或上一次调节)中，检测到的当前加热温度值与目标温度值之间的差值所对应的差值量化值。
如前所述，目标占空比调节值的确定可以按照如下公式进行确定：
也就是说，在当前的PWM占空比不为0且加热电阻当前的温度不超过目标温度一定范围的情况下，对PWM占空比的调节幅度为在原来的PWM占空比的基础上加上两倍的本次调节的检测到的温度差值的量化值并减去上一次调节的过程中检测到的温度差值的量化值，即为PID(proportion-integral-derivative，比例、积分、微分控制)调节。而在加热电阻的温度超过目标温度一定范围的情况下，将PWM占空比设置为0；且在当前PWM占空比不为0的情况下，获取该PWM占空比的具体值为缓存值。而在PWM占空比清零之后，当加热电阻的温度下降到目标温度时，价格清零之前的PWM占空比进行恢复，并重新启动PID调节。
在一个具体的实施例中，可以对当前加热温度值与目标温度值之间的差值值、与差值量化值之间的对应关系，例如，可以为线性函数或者非线性函数，也可以为阶梯函数。
在一个具体的实施例中，为了避免细微的温度差别所带来的频繁的PWM占空比的调节对电子烟处理器所带来的负担，当前加热温度值与目标温度值之间的差值值、与差值量化值之间的对应关系可以采用阶梯函数。例如，采用如下 的函数定义：
其中，E为差值量化值，ΔT为目标温度值与当前加热温度值之间的差值，即：ΔT＝T
t-T
N。
在其他实施例中，当前加热温度值与目标温度值之间的差值值、与差值量化值之间的对应关系可以采用任何的正相关的函数。
此外，为解决传统技术中对加热型电子烟的加热温度的控制存在控制准确率不足的技术问题，，在一个实施例中，如图5所示，还提出了一种电子烟加热温度的控制装置，该电子烟设备包括加热电路，所述加热电路包括加热电阻，所述加热电路的输入端与PWM输出端连接；通过所述加热电路给所述加热电阻供电以给放置在所述电子烟设备中的可抽吸材料加热以供用户进行抽吸。
