技术领域
本发明涉及计算机技术领域,具体涉及一种风扇调速方法、装置及电子设备。
背景技术
在服务器市场中,由于风冷散热具有高性价比、高可靠性和易维护等优势,服务器散热系统通常均采用风冷散热。对于风冷散热系统中风扇转速的调控,一般都是基于主要发热器件的温度进行调控,当温度达到设定的阈值时会有对应的风扇转速。
然而发明人通过研究发现,随着服务器性能需求的增加,服务器的发热器件的温度变化剧烈,这样依据目前的转速调整方法,只有当服务器的发热器件的逐步升温到风扇的调速温度时,才会触发风扇进行转速调整,而此时发热器件的热量其实已经集聚了很长时间,导致风扇需要利用更高的转速或者更多的时间才能将发热器件的温度调整到合理温度。综上,目前的风扇调速无法适应发热器件的温度变化速率,导致风扇调速实时性较差,严重时甚至影响散热效率。
因此,如何能够提高风扇调速的实时性,进而提高散热效率是本领域技术人员亟需解决的技术问题。

为了使本技术领域的人员更好地理解本发明中的技术方案,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做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。

为了更加清楚的描述本发明实施例提供的风扇调速方法,参见图1,是本发明实施例提供的一种应用风扇调速方法的硬件结构示意图,如图1所示,发热器件1可以包括服务器系统中需要重点关注的核心器件,例如CPU(英文:Central Processing Unit,中文:中央处理器)、GPU(英文:Graphics Processing Unit,中文:图形处理器)、内存以及硬盘等。检测器2可以包括电流检测器、温度传感器、VR(英文:Voltage Regulator,中文:电压调整器)等的一种或多种,该检测器2可以实现对发热器件1的电流、电压、温度等的检测,从而实时、准确地获知发热器件1在工作电流、工作电压、工作温度等,并将上述信息发送给控制器3。在发明实施例中,控制器3用于根据从检测器获得的上述信息控制风扇转速,其中,控制器3可以包括BMC(英文:Baseboard Management Controller,中文:基板管理控制器)或者其他CPLD(英文:Complex Programmable Logic Device,中文:复杂可编程逻辑器件)、FPGA(英文:Field Programmable Gate Array,中文:现场可编程门阵列)等处理芯片,甚至,为了节省成本,服务器系统中的CPU或者GPU也可以作为该控制器3使用对风扇转速进行控制。在发明实施例中,将以控制器3作为实施主体,详细描述控制器3进行风扇调速的控制过程。
当然,需要说明的是,上述执行该风扇调速方法的硬件结构仅是一示意性结构,在具体实施时,该风扇调速方法还可以应用于其他任意的硬件结构,在本发明实施例中不再赘述。
另外,本发明实施例进一步结合一个示例性的应用场景对风扇调速过程进 行描述,参见图2,是本发明实施例提供的一种应用风扇调速方法的场景示意图,如图2所示,在本发明实施例中,主板4上配置有第一内存51、第二内存52、第三内存53和第四内存54,第一处理器61和第二处理器62,以及第一风扇71、第二风扇72、第三风扇73、第四风扇74和第五风扇75;其中,第一内存51、第二内存52、第三内存53和第四内存54均配置4根内存条;第一处理器61和第二处理器62可以包括CPU、GPU、CPLD和FPGA中的一种或多种。在散热设计中,上述第一内存51、第二内存52、第三内存53、第四内存54、第一处理器61和第二处理器63作为主要的发热器件进行重点监控,检测器可以对上述内存和处理器器件进行电流和/或温度的检测。在风道设计上,第一内存51和第二内存52可以处于第一风道(未示出),对应第一风扇71进行散热处理。第一处理器61和第二处理器62可以处于第二风道(未示出),由第二风扇72、第三风扇73和第四风扇74进行散热处理;或者,第一处理器61和第二处理器62处于相互独立的风道中,第一处理器61对应第二风扇72进行散热处理,第二处理器62对应第三风扇73和第四风扇74进行散热处理。第三内存53和第四内存54处于第三风道(未示出),由第五风扇75进行散热处理。
需要说明的是,风扇调速方法的应用场景也仅是一示例性实施例中,上述内存、处理器的分布以及风道设计等也仅是一示例性实施例,为了描述方便本发明实施例将结合图2所示的应用场景进行详细描述。当然,本发明实施例提供的风扇调速方法同样可以应用于其他散热设计场景,在本发明实施例中不再赘述。
参见图3,是本发明实施例提供的一种风扇调速方法的流程示意图,如图3所示,本发明实施例示出了控制器实施该风扇调速方法的过程:
步骤S101:获取各个发热器件的特征信息和工作电流,所述特征信息用于描述发热器件的特征。
该特征信息可以包括器件类型、器件的功耗、以及目标温度的一种或多种的结合。其中,器件类型用于描述发热器件的类型、规格等,在一示例性实施例中,该器件类型可以包括内存、CPU、GPU等,这样通过该器件类型能够进一步区分该发热器件是内存、CPU或者GPU。器件的功耗可以为发热器件 的额定功耗或者峰值功耗等,用于描述发热器件在工作时的功耗情况。该目标温度,是依据服务器散热设计,设定的该发热器件最高的工作温度,在具体温度控制中,需要控制该发热器件不高于该目标温度,而且,不同的发热器件可以具有相同或者不同的目标温度。这样,通过上述特征信息,控制器可以在后续步骤中根据该器件类型匹配不同的电流转速表,以针对不同发热器件的实施不同控制策略。
另外,在具体实施时,各个发热器件的特征信息可以存储于寄存器中,控制器通过访问该寄存器获取各个发热器件的特征信息,在本发明实施例中对特征信息的存储方式不做限定,该特征信息可以存储于发热器件自身的寄存器,或者独立设置在主板上的寄存器中;而且,控制器与寄存器的通信方式也不做限定,可以通过I2C总线的方式进行访问。
步骤S102:选择与所述特征信息相匹配的电流转速表。
为了实现对电流转速表的统一管理,可以建立电流转速表的列表库,该列表库用于管理一个或多个电流转速表,且每个电流转速表与上述特征信息具有对应关系。对于一个电流转速表,用于描述针对一个特征信息的发热器件,电流和转速的对应关系,即一个电流对应一个转速。
在具体实施时,根据服务器系统的整体散热设计,各个发热器件需要控制到不同目标温度,即各个发热器件不高于各自的目标温度,才能实现整体散热效果,为了实现各个发热器件的精确控制,不同的发热器件采用不同的控制策略。而且,通过建立电流转速表数据库的方式,能够实现不同类型、规格发热器件的自动匹配,无需人工一一制定散热策略,提高复用性和该调速方法的灵活性。
在第一种实施情况下,参见图4,是本发明实施例提供的一种电流转速表匹配方法的流程示意图,如图4所示,该方法示出了通过器件类型和目标温度实现不同类型器件灵活调速的过程,该方法包括:
步骤S1021:从列表库中选择与所述器件类型相匹配的列表集,其中,所述列表库包括对应不同器件类型的列表集。
在本发明实施例中,该列表库的实现方式是:按照器件类型分为多个列表集,每个列表集中进一步按照不同的目标温度分为多个电流转速表。如表一所 示,在一示例性实施例中,该列表库包括GPU列表集、CPU列表集和内存列表集;对于GPU列表集,针对不同的目标温度存在相应的电流转速表,即GPU-30电流转速表代表GPU的目标温度为30℃的电流转速表,GPU-50电流转速表代表GPU的目标温度为50℃的电流转速表,GPU-70电流转速表代表GPU的目标温度为70℃的电流转速表,对于其他CPU列表集、内存列表集具有上述相同的定义规则,在此不再赘述。这样就建立了对应不同器件类型和目标温度的列表库。
表一:
列表集 30℃ 50℃ 70℃
GPU GPU-30电流转速表 GPU-50电流转速表 GPU-70电流转速表
CPU CPU-30电流转速表 CPU-50电流转速表 CPU-70电流转速表
内存 内存-30电流转速表 内存-50电流转速表 内存-70电流转速表
步骤S1022:从所述列表集中选择与所述目标温度相匹配的电流转速表,其中,所述列表集包括目标温度的电流转速表。
在匹配过程中,可以根据上述步骤获取得到的器件类型和目标温度,选择对应的电流转速表。在一示例性实施例中,当获取到器件类型为CPU,目标温度为50℃时,则可以选择CPU列表集,并进一步从CPU列表集中选择CPU-50电流转速表。这样,通过上述过程,可以实现对所有类型发热器件的电流转速表的匹配。
在第二种实施情况下,参见图5,是本发明实施例提供的另一种电流转速表匹配方法的流程示意图,如图5所示,该方法示出了通过发热器件的功耗和目标温度实现不同规格的发热器件灵活调速的过程,该方法包括:
步骤S1023:从列表库中选择与所述器件功耗相匹配的列表集,其中,所述列表库包括对应不同器件功耗的列表集。
步骤S1024:从所述列表集中选择与所述目标温度相匹配的电流转速表,其中,所述列表集包括不同目标温度的电流转速表。
根据上述实施例的描述,同样可以通过器件功耗和目标温度匹配选择相应的电流转速表。在一示例性实施例中,当获取到器件功耗为20W,目标温度 为30℃时,则可以选择20W对应的列表集,并机一部从20W列表集中选择30℃对应的电流转速表。这样,通过上述过程,可以实现所有功耗指标发热器件的电流转速表的匹配。
在第三种实施情况下,参见图6,是本发明实施例提供的又一种电流转速表匹配方法的流程示意图,如图6所示,该方法示出了通过发热器件的类型和功耗实现不同类型、规格的发热器件灵活调速的过程,该方法包括:
步骤S1025:选择与第一器件类型相匹配的第一电流转速表。
步骤S1026:选择与第二器件类型相匹配的第二电流转速表,其中,在相同温度区间内,第一电流转速表的转速差大于第二电流转速表的转速差。
本发明实施例示出了对于不同功耗的发热器件,配置特定的电流转速表。在一示例性实施例中,第一器件类型为CPU,第二器件类型为内存,则根据上述第一器件类型和第二器件类型,针对CPU发热器件获取CPU电流转速表,如表二所示,针对内存发热器件获取内存电流转速表,如下一页表三所示。由于CPU的功耗大于内存的功耗,在一示例性实施例中,要求针对CPU类型的发热器件的转速变化速率要大于内存类型的发热器件的转速变化速率,结合表二和下一页表三,在6A-8A的电流区间内,对于CPU发热器件,转速差值为1000,对于内存发热器件,转速差值为500,这样对于热量集聚快的器件可以通过增大电流转速调节速度的方式加快散热,对于热量集聚慢的器件可以通过减小电流转速调节速度的方式节省功耗。
表二:
电流(A) 转速(转/秒)
8 5000
6 4000
4 3000
2 1000
需要说明的是,上述实施例仅是一示例性实施例,在具体实施时还可以通过器件类型、目标温度、发热器件功耗的一种或多种结合的方式,从电流转速表库中进行选择。例如,仅是通过器件类型、目标温度和发热器件功耗的一种 进行匹配得到对应的电流转速表,或者,结合器件类型、目标温度和发热器件功耗三者匹配的方式选择电流转速表。
表三:
电流(A) 转速(转/秒)
8 4000
6 3500
4 3000
2 2500
另外,在具体实施时,可以进一步结合风道设计情况,根据同一风道内不同特征信息的发热器件,选择相应的电流转速表。
在第一种实施情况下,当位于同一风道的发热器件具有相同类型时,则选择目标温度高的电流转速表。第一内存51和第二内存52位于同一风道内,第一内存51的器件类型为内存,目标温度为30℃,第二内存52的器件类型为内存,目标温度为50℃,则选择类型为内存、目标温度为50℃的电流转速表。
在第二种实施情况下,当位于同一风道的发热器件具有不同类型时,则选择功耗高的电流转速表。当第一处理器61和第一内存51位于同一风道时,第一处理器61的器件类型为CPU,功耗为20W,第一内存51的器件类型为内存,功耗为10W,则选择类型为CPU,功耗为20W的电流转速表。
步骤S103:根据选择出的电流转速表,确定与所述工作电流相对应的转速,并将发热器件相对应的风扇设定为所述转速。
在一示例性实施例中,结合图2所示的应用场景,第一内存51和第二内存52位于同一风道,且第一风扇71用于实现第一内存51和第二内存52的散热,根据上述步骤选择类型为内存、目标温度为50℃的电流转速表,进一步根据第一内存51和第二内存52的工作电流,从电流转速表中选择该工作电流对应的转速,控制第一风扇71工作在该转速。
在另一示例性实施例中,结合图2的应用场景,当第一处理器61和第一内存51位于同一风道时,第一处理器61的器件类型为CPU,功耗为20W,第一内存51的器件类型为内存,功耗为10W,则选择类型为CPU,功耗为 20W的电流转速表,且在该风道内第二风扇72用于控制散热。则进一步根据选择出的电流转速表对应的发热器件的工作电流,即第一处理器61的工作电流,选择相应的转速,并将该第二风扇72配置在该转速。
由上述实施例的描述可见,本发明实施例提供的一种风扇调速方法,通过获取各个发热器件的特征信息和工作电流,所述特征信息用于描述发热器件的特征;选择与所述特征信息相匹配的电流转速表;根据选择出的电流转速表,确定与所述工作电流相对应的转速,并将发热器件相对应的风扇设定为所述转速。本发明通过特征匹配的方式,对每个发热前进对应的风扇进行针对性调控,有效提高了散热效率,而且,通过电流响应的方式,对应不同发热器件进一步提高了风扇调整速度,提高了散热实时性。
在具体风扇调速过程中,随着发热器件老化或者工作环境、工作参数的调整,原有的电流转速表可能出现偏差,为了适应这种环境变化,进一步提高风扇调速的灵活性和效率,本发明实施例对电流转速表进行动态更新。
在第一种实施情况下,参见图7,是本发明实施例提供的另一种风扇调速方法的流程示意图,如图7所示,该方法包括以下步骤:
步骤S201:获取各个发热器件的特征信息和工作电流,所述特征信息用于描述发热器件的特征。
步骤S202:选择与所述特征信息相匹配的电流转速表。
步骤S203:根据选择出的电流转速表,确定与所述工作电流相对应的转速,并将发热器件相对应的风扇设定为所述转速。
步骤S204:获取发热器件的检测温度。
步骤S205:当检测温度大于阈值温度时,在选择出的电流转速表中,增加工作电流对应的转速。
在将风扇转速设定为相应的转速后,进一步检测发热器件的检测温度。在一示例性实施例中,第一内存51对应第一风扇71,在根据第一内存51对应的电流转速表调整风扇转速后,获取第一内存51的检测温度。预设一阈值温度,该阈值温度可以为根据散热设计设定的第一内存51工作的最高温度,或者上述实施例中的目标温度,当该检测温度高于该阈值温度时,表征当前的转速不能满足散热需求,则进一步对该内存对应的电流转速表进行修正,增加第 一内存51当前工作电流对应的风扇转速。
本发明实施例与上述实施例相同之处,可参见上述实施例的描述,在此不再赘述。
由上述实施例的描述可见,本发明实施例提供的另一种风扇调速方法,根据温度阈值的判断,将温度和电流控制相结合,使用温度检测作为电流调速方式的校验,进而对电流风扇转速表进行修正,保证了电流转速表的准确性,提高散热效率。
在第二种实施情况下,参见图8,是本发明实施例提供的再一种风扇调速方法的流程示意图,如图8所示,该方法包括以下步骤:
步骤S301:获取各个发热器件的特征信息和工作电流,所述特征信息用于描述发热器件的特征。
步骤S302:选择与所述特征信息相匹配的电流转速表。
步骤S303:根据选择出的电流转速表,确定与所述工作电流相对应的转速,并将发热器件相对应的风扇设定为所述转速。
步骤S304:依次获取发热器件的第一检测温度和第二检测温度。
步骤S305:当第二检测温度大于第一检测温度时,在选择出的电流转速表中,增加工作电流对应的转速。
本发明实施例与上述实施例相同之处,可参见上述实施例的描述,在此不再赘述。
在将风扇转速设定为相应的转速后,进一步检测发热器件的检测温度变化趋势。在一示例性实施例中,第一处理器61对应第二风扇72,在根据第一处理器61对应的电流转速表调整风扇转速后,按照时间先后依次获取第一处理器61的第一检测温度43℃和第二检测温度44℃。由于第二检测温度大于第一检测温度,表征当前的转速不能满足散热需求,则进一步对该处理器对应的电流转速表进行修正,增加第一处理器61当前工作电流对应的风扇转速.
由上述实施例的描述可见,本发明实施例提供的再一种风扇调速方法,根据温度变化趋势的判断,将温度和电流控制相结合,使用温度检测作为电流调速方式的校验,进而对电流风扇转速表进行修正,保证了电流转速表的准确性,提高散热效率。
通过以上的方法实施例的描述,所属领域的技术人员可以清楚地了解到本发明可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质中,包括若干指令用以使得一台计算机设备(可以是个人计算机,服务器,或者网络设备等)执行本发明各个实施例所述方法的全部或部分步骤。而前述的存储介质包括:只读存储器(ROM)、随机存取存储器(RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
