rec*_*gle 15 python windows cpu temperature
我需要一个示例代码来访问python中的CPU温度.
我正在运行Windows 7,BTW.
使用此处描述的WMI模块 + Open Hardware Monitor +其WMI接口.
示例代码:
import wmi
w = wmi.WMI(namespace="root\OpenHardwareMonitor")
temperature_infos = w.Sensor()
for sensor in temperature_infos:
if sensor.SensorType==u'Temperature':
print(sensor.Name)
print(sensor.Value)
您可以使用pywin32访问本机 Windows API。如果主板驱动程序的制造商通过他们的驱动程序注册了 WMI 数据提供程序，我相信应该可以查询 Windows API 的 CPU 温度。假设是这种情况，您可以下载ars回答中提到的pywin32扩展和Python WMI模块，然后按以下步骤操作：
import wmi
w = wmi.WMI()
print w.Win32_TemperatureProbe()[0].CurrentReading
查看 ars 答案中的 IronPython 脚本，似乎还有另一种方法可以使用不同的 WMI 对象。使用相同的 API 和方法，您可以尝试使用以下方法接收温度值
w = wmi.WMI(namespace="root\wmi")
temperature_info = w.MSAcpi_ThermalZoneTemperature()[0]
print temperature_info.CurrentTemperature
这显然应该以十分之一开尔文返回温度值，因此要获得摄氏度我猜你只需将此值除以 10 并减去 ~273。
下载http://openhardwaremonitor.org/downloads/和http://www.cputhermometer.com/并解压缩OpenHardwareMonitorLib.dll和CPUThermometerLib.dll并将它们放在目录中。
然后，您可以使用pythonnet模块寻址.dll，并提取这些程序提供的任何统计信息。cputhermometer提供每核CPU温度，openhardwaremonitor提供其他所有功能。无需使用WMI，它要求程序在后台处于活动状态。
我编写了一个小脚本（python 3.6.5）来显示系统上可用的每个温度传感器，您当然可以轻松地针对其他传感器类型进行修改。您必须以管理员身份运行：
import clr #package pythonnet, not clr
openhardwaremonitor_hwtypes = ['Mainboard','SuperIO','CPU','RAM','GpuNvidia','GpuAti','TBalancer','Heatmaster','HDD']
cputhermometer_hwtypes = ['Mainboard','SuperIO','CPU','GpuNvidia','GpuAti','TBalancer','Heatmaster','HDD']
openhardwaremonitor_sensortypes = ['Voltage','Clock','Temperature','Load','Fan','Flow','Control','Level','Factor','Power','Data','SmallData']
cputhermometer_sensortypes = ['Voltage','Clock','Temperature','Load','Fan','Flow','Control','Level']
def initialize_openhardwaremonitor():
file = 'OpenHardwareMonitorLib.dll'
clr.AddReference(file)
from OpenHardwareMonitor import Hardware
handle = Hardware.Computer()
handle.MainboardEnabled = True
handle.CPUEnabled = True
handle.RAMEnabled = True
handle.GPUEnabled = True
handle.HDDEnabled = True
handle.Open()
return handle
def initialize_cputhermometer():
file = 'CPUThermometerLib.dll'
clr.AddReference(file)
from CPUThermometer import Hardware
handle = Hardware.Computer()
handle.CPUEnabled = True
handle.Open()
return handle
def fetch_stats(handle):
for i in handle.Hardware:
i.Update()
for sensor in i.Sensors:
parse_sensor(sensor)
for j in i.SubHardware:
j.Update()
for subsensor in j.Sensors:
parse_sensor(subsensor)
def parse_sensor(sensor):
if sensor.Value is not None:
if type(sensor).__module__ == 'CPUThermometer.Hardware':
sensortypes = cputhermometer_sensortypes
hardwaretypes = cputhermometer_hwtypes
elif type(sensor).__module__ == 'OpenHardwareMonitor.Hardware':
sensortypes = openhardwaremonitor_sensortypes
hardwaretypes = openhardwaremonitor_hwtypes
else:
return
if sensor.SensorType == sensortypes.index('Temperature'):
print(u"%s %s Temperature Sensor #%i %s - %s\u00B0C" % (hardwaretypes[sensor.Hardware.HardwareType], sensor.Hardware.Name, sensor.Index, sensor.Name, sensor.Value))
if __name__ == "__main__":
print("OpenHardwareMonitor:")
HardwareHandle = initialize_openhardwaremonitor()
fetch_stats(HardwareHandle)
print("\nCPUMonitor:")
CPUHandle = initialize_cputhermometer()
fetch_stats(CPUHandle)
这是我系统上的输出：

有关进一步的文档（但是您应该能够从上述代码中推断出所需的一切），请参阅https://github.com/openhardwaremonitor/openhardwaremonitor/（或网站上的cputhermometer）源代码，功能和方法。与python一起使用时是相同的。
我没有在其他任何计算机上进行过测试，因此不同的处理器体系结构可能无法完全相同。
确保您Hardware[x].Update()在进行测量之间进行测量（SubHardware[x].Update()如果需要）。

我从第 3 方收到了一个 C++ 项目，并找到了如何使用 C++ 获取 CPU 和电路板温度。然后我发现了这个，我用来帮助我用 ctypes 模拟 python 中的 C++ 函数，很多代码是直接从该存储库复制的。'\\.\AdvLmDev' 特定于我使用的 PC，应替换为 '\\.\PhysicalDrive0'。还有一个功能可以获取其他 CPU 功率测量值。我这样做是因为我不想使用 Open Hardware Monitor。您可能必须以管理员身份运行代码才能使其工作。
