(3)设定常量ΔT：为温度容差。根据PTN设备的具体情况进行设定，用于判定PTN设备是否需要调节PTN设备风扇转速。如果PTN设备温度相 对于目标温度值，下降差值大于或等于ΔT，则需要重新设定PTN设备风扇的转速。其中，ΔT参考取值为，如果温度采集时间间隔小于20S，则ΔT＝2；若大于20S，则ΔT＝3，根据具体情况而定。
(4)设定常量ΔSP：为PTN设备风扇转速调节幅度，单位为转/分钟。即，一个档位对应的转速变化，根据具体情况进行设定。

Figure PCTCN2015071652-appb-000004
目标调速策略算法的原理：如(3.1)、(3.2)和(3.3)、(3.4)所示，比较PTN设备当前采集温度值与目标温度值的大小。
其中，(3.1)和(3.2)的原理：
如(3.1)所示，如果PTN设备当前采集温度值大于目标温度值，则设定PTN设备风扇转速为提高一个调节幅度的PTN设备风扇转速；
如(3.2)所示，如果PTN设备当前采集温度值不大于目标温度值，则需要判断目标温度值与PTN设备当前采集温度值的差值。
(3.3)和(3.4)的原理：
如(3.3)所示，如果差值大于或等于温度容差ΔT，则设定PTN设备风扇转速为降低一个调节幅度的PTN设备风扇转速。
如(3.4)所示，如果差值小于温度容差ΔT，PTN设备风扇转速不变；
按照以上算法实现PTN设备风扇的转速控制，使PTN设备温度最终稳定在目标温度值Tobj处，在温度容差ΔT的温度范围之内，PTN设备风扇转速保持不变。具体的步骤为：
步骤301：读取PTN设备主控板的当前采集温度值。
步骤302：计算PTN设备主控板的当前采集温度值与目标温度值的差值。如果PTN设备主控板的当前采集温度值大于目标温度值，执行步骤303；如果PTN设备主控板的当前采集温度值不大于目标温度值，转步骤304。
步骤303：重新计算PTN设备风扇的转速值，转步骤306。

步骤305：保持PTN设备风扇的转速不变。
步骤306：PTN设备主控板将PTN设备风扇转速值通过智能型平台管理接口(IPMI：Intelligent Platform Management Interface)发送给PTN设备风扇。
图4是本发明实施例提供的用于PTN设备风扇调速的线性调速流程图，如图4所示，根据不同单板布局的PTN设备的需求，在高温或常温下，PTN设备温度随环境温度成线性变化的情况适用于线性调速策略算法。即，如果环境温度升高，PTN设备温度也随之升高，为了使PTN设备的温度保持稳定，提出线性调速策略算法。PTN设备风扇线性调速的算法如下：
(1)设定PTN设备的温度调节范围为(Tmin,Tmax)；
(2)设定PTN设备风扇的转速范围为(SPmin,SPmax)；
(3)设定温度容差为常量ΔT：根据具体情况进行设定，用于调节PTN设备风扇档位。
(4)设定PTN设备风扇有N个档位。每个档位对应的PTN设备风扇转速变化值为ΔSP＝(SPmax-SPmin)/N。其中，N的取值可根据(Tmin,Tmax)设定，例如：N＝Tmax-Tmin，也可以取值为N＝(Tmax-Tmin)/2，仅供参考，需根据实际情况进行设定。
设定某时刻t(在前反馈时刻)，PTN设备温度传感器反馈温度值为Tt，PTN设备风扇转速为SPt；时刻t+1时(当前反馈时刻)，读取PTN设备温度传感器反馈温度值为Tt+1，需要以下两步算法进行计算：

其中，(4.1)、(4.2)和(4.3)的原理：
如(4.1)所示，如果PTN设备当前采集温度值低于温度调节范围的最低温度值，则设定PTN设备风扇转速为最低档对应的转速SPmin；
如(4.2)所示，如果PTN设备当前采集温度值高于温度调节范围的最高温度值，则设定PTN设备风扇转速为最高档对应的转速SPmax；
如(4.3)所示，如果PTN设备当前采集温度值处于温度调节范围之内，则需要判断当前采集温度值与在前采集温度值的差值，根据(4.4)和(4.5)计算PTN设备风扇的转速。
(4.4)和(4.5)的原理：
如(4.4)所示，如果PTN设备当前采集温度值高于在前采集温度值，则需要计算当前采集温度值与最低温度值的差值，根据差值和最低档转速计算出当前PTN设备风扇的转速；
如(4.4)所示，如果PTN设备当前采集温度值相对于在前采集温度值，下降差值大于或等于温度容差ΔT，则需要根据差值和最低档转速计算出当前PTN设备风扇的转速；
如(4.5)所示，如果PTN设备当前采集温度值相对于在前采集温度值，下降差值小于温度容差ΔT，PTN设备风扇转速维持不变。
按照以上算法实现PTN设备风扇的转速控制，智能调节PTN设备温度，使PTN设备不至于因为温度过高而出现工作异常。具体的步骤为：
步骤401：读取PTN设备主控板的当前采集温度值。
步骤402：计算PTN设备主控板的当前采集温度值与在前采集温度值的差值。如果PTN设备主控板的当前采集温度值大于在前采集温度值，执行步骤403；如果PTN设备主控板的当前采集温度值不大于在前采集温度值，转步骤404。
步骤403：重新计算PTN设备风扇的转速值，转步骤406。
步骤404：如果PTN设备主控板的当前采集温度值相对于在前采集温度值，下降差值大于或等于温度容差，执行步骤403；如果PTN设备主控板的当前采集温度值相对于在前采集温度值，下降差值小于温度容差，执行步骤405。
步骤405：保持PTN设备风扇的转速不变。
步骤406：PTN设备主控板将PTN设备风扇转速值通过IPMI发送给PTN设备风扇。
步骤407：PTN设备风扇根据转速值调节自身转速。
