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 于本申请保护的范围。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结果或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
为了更好地理解本申请实施例的技术方案，下面，结合图1和图2中的步骤对本申请实施例提供的一种充电桩降温的方法进行详细说明。
请参见图1，为本申请实施例提供的一种充电桩降温的方法的流程示意图，可包括以下步骤：
S101，按第一预设周期确定第一预设噪音值。
在一种可能的实施方式中，每隔第一预设周期，根据当前时间节点确定第一预设噪音值，该第一预设噪音值的大小与当前时间节点相关。
示例性的，若第一预设周期为1分钟，则充电桩的采集模块就会每间隔一分钟获取确认当前时间节点，而计算模块则会根据当前时间节点确定第一预设噪音值。其中，上述第一预设周期的选定只是为了举例说明本申请实施例方法，不应对本申请构成限定，具体的第一预设周期数值由技术人员根据实际情况进行设定。
需要说明的是，在本申请实施例中，第一预设噪音值与时间存在着一定的相关性。技术人员可以通过实验得出在不同时间节点下(或者不同的季节)，人们对于噪音的容忍程度，并以此得到第一预设噪音值。技术人员可以将第一预设噪音值与时间节点的关系制作成可查询表格或者拟合成相关函数，并存储于充电桩中。这样，不管是用查表的方式还是用计算的方式，充电桩都能快速地确定当前时间节点的第一预设噪音值。
其中，人们用分贝来划分声音的等级。0分贝是人们刚刚能听到的最弱声，即听觉下限，10分贝相当于微风吹落树叶的沙沙声。30～40分贝是较理想的安静环境。超过50分贝就会影响睡眠和休息。70分贝以上会干扰谈话，影响工作效率。长期生活在90分贝以上的噪声环境，会严重影响听力和引起神经衰弱、头疼、血压升高等疾病。如果突然暴露在高达150分贝的噪声环境中，听觉器官会发生急剧外伤，引起鼓膜破裂出血，双耳完全失去听力。为了保护听力，应控制噪声不超过90分贝；为了保证工作和学习，应控制噪声不超过70分贝为了保证休息和睡眠，应控制噪声不超过50分贝。
噪声在0～120分贝的范围内分为三级：(1)Ⅰ级(30～59分贝)：可以忍受，但已有不舒适感，达到40分贝时开始困扰睡眠。(2)Ⅱ级(60～89分贝)：对******的干扰增加，听话困难，85分贝是保护听力的一般要求。(3)Ⅲ级(90～120分贝)：显著损害神经***，造成不可逆的听觉器官损伤。
示例性的，根据噪音等级的划分，在休息时段(如21:00～7:00，13:00～14:30)，人们需要比较安静的休息环境，可以将第一预设噪音值设置为45分贝；在工作时段(如9:00～12:00，14:30～18:00)，可以将第一预设噪音值设置为70分贝。
更多地，不同的季节与第一预设噪音值之间的对应关系也可能会存在差异。比如在冬季 和夏季这种会时常出现极端天气的季节里，人们在户外的时间减少，充电桩的噪音对人们的生活影响也会变小，所以第一预设噪音值可以相应地提高。
示例性的，在春季或者秋季时，充电桩在12:00的第一预设噪音值为50分贝。那么在冬季或者夏季时，可以将第一预设噪音值调整至70分贝。需要强调的是，上述举例均是为了对本申请实施例进行详细说明，不应对本申请构成限定，具体的第一预设噪音值由技术人员根据实际情况进行设定。
S102，根据所述第一预设噪音值确定充电桩风机的第一速度。
需要说明的是，第一速度为在充电桩风机制造的噪音超过第一预设噪音值时，该充电桩风机能达到的最大运转速度。其中，技术人员会根据充电桩风机不同的运转速度得到对应的噪音值，以此确定充电桩风机的运转速度与噪音值之间的关系。充电桩风机的运转速度与充电桩的噪音值呈正向关系，即充电桩风机的运转速度越大，充电桩风机发出的噪音也就越大。因此，能够根据第一预设噪音值确定充电桩风机的最大运转速度。
在一种可能的实施方式中，根据第一速度确定充电桩的充电模块的第一功率。并且控制充电模块的运行功率不超过第一功率。
其中，技术人员可以测量记录在不同的充电桩风机转速下充电模块能达到的最大运行功率，来确定充电桩风机转速与充电模块的最大运行功率之间的功率。充电桩风机的运转速度与充电模块的最大运行功率之间也呈正向关系，充电桩风机的运转速度越大，充电模块能达到的最大运行功率也就越大。这是由于充电模块的运行功率与工作环境温度有关，过高的工作环境温度会抑制充电模块的工作效率。而充电桩风机的运转速度越大，对充电模块工作环境的降温效果就会越明显，因此充电模块能够达到的运行功率最大值就会增加。
可以看出，本申请实施例能够根据充电桩工作的当前时间节点确定充电桩风机的最大运转速度，降低对周围环境的噪音污染，并得出充电模块的最大运行功率。控制充电模块的运行功率不超过该最大运行功率，避免充电模块因超负荷工作而造成故障。
请参见图2，为本申请实施例提供的另一种充电桩降温的方法的流程示意图，可包括以下步骤：
S201，按第三预设周期获取所述充电桩风机的第三速度。
需要说明的是，第三速度为充电桩风机的实际运转速度。
示例性的，若第三预设周期为30秒，则充电桩的采集模块便每隔30秒获取充电桩风机的实际转速(即第三速度)。以较小的第三预设周期获取充电桩风机的实际运转速度有利于更加精准地对充电桩风机运转速度进行调控，便于为充电模块营造更稳定的工作环境。其中，上述对第三预设周期的举例只是为了更加详细地描述本申请实施例方法，不应对本申请构成限定，具体的第三预设周期的数据由技术人员根据实际情况进行设定。
在一种可能的实施方式中，在按第三预设周期获取充电桩风机的第三速度之前，还会按第二预设周期获取充电模块的第二功率。其中，该第二功率为充电模块的实际运行功率。
示例性的，若第二周期为30秒，则充电桩的采集模块便会每隔30秒获取充电模块的运行功率。若第一次获取到的充电模块的运行功率为1000瓦，第二次获取到的充电模块的运行功率为800瓦，则可以用于指示降低充电桩风机的运转速度。周期性地获取充电模块的运行功率有利于及时对充电桩风机的运转速度进行调节，避免了对充电桩风机的过度消耗以及能源浪费。
其中，充电模块的实际运行功率会受到第一功率(即充电桩风机以第一速度运转时，充电模块能达到的最大功率)的限制。示例性的，充电桩(第一功率为1000瓦)为车辆A提 供充电服务，若车辆A所需的电流大小需要充电桩以800瓦的功率工作，则充电桩会以800瓦作为运行功率进行工作；若车辆A所需的电流大小需要充电桩以1200瓦的功率工作，则充电桩只会以1000瓦作为运行功率工作，因为目前充电桩的工作功率无法超过第一功率。
更多地，根据第二功率确定第二速度。其中，该第二速度为保证充电模块能以第二功率运行时充电桩风机的运转速度。
S202，根据所述第二速度以及所述第三速度生成控制速度。
其中，控制速度由第二速度以及第三速度之间的差值的比例和积分通过线性组合得到。其中，PI调节器根据充电桩风机的实际运行速度(即第三速度)和目标速度(即第二速度)，动态地调和出控制速度，使得充电桩风机能够以稳定的运转速度工作。PI调节器是一种线性控制器，它根据给定值与实际输出值构成控制偏差，将偏差的比例和积分通过线性组合构成控制量，对被控对象进行控制。比例调节作用为：按比例反应***的偏差,***一旦出现了偏差,比例调节立即产生调节作用用以减少偏差。比例作用大,可以加快调节,减少误差,但是过大的比例,使***的稳定性下降,甚至造成***的不稳定。积分调节作用为：使***消除稳态误差,提高无误差度。因为有误差,积分调节就进行,直至无差,积分调节停止,积分调节输出一常值。积分作用的强弱取决于积分时间常数Ti，Ti越小，积分作用就越强。反之Ti越大，则积分作用越弱,加入积分调节可使***稳定性下降,动态响应变慢。积分作用常与另两种调节规律结合,组成PI调节器或PID调节器。
在本申请实施例中，控制速度会慢慢趋近于第二速度。
S203，根据所述控制速度对充电桩的转速进行调整。
可以看出，本申请实施例能够根据充电模块的实际运行功率对充电桩风机的运转速度进行调整，有利于节约充电桩风机能源，避免不必要的资源浪费。而且通过PI调节器对充电桩风机的运转速度进行调控，让充电桩风机的运转速度围绕目标速度小幅度波动，有利于充电桩风机稳定运行，能为充电模块提供良好的工作环境。
