windows用c++获取cpu温度
时间: 2023-02-21 22:35:36 浏览: 527
很抱歉,获取 CPU 温度并不是一件简单的事情,因为 Windows 操作系统本身不提供直接获取 CPU 温度的 API。你可以使用第三方软件来读取 CPU 温度信息,然后通过 Windows API 来调用这些第三方软件,最后再通过 C 语言来获取 CPU 温度。
以下是一个示例代码:
```c
#include <stdio.h>
#include <Windows.h>
int main()
{
// 运行第三方软件,获取 CPU 温度信息
system("third-party-software.exe > temp.txt");
// 读取文件中的 CPU 温度信息
FILE *fp = fopen("temp.txt", "r");
float temperature;
fscanf(fp, "%f", &temperature);
fclose(fp);
// 输出 CPU 温度
printf("CPU temperature: %.2f\n", temperature);
return 0;
}
```
请注意,上述代码仅作为示例,具体实现方式可能因第三方软件不同而有所差异。

c++ 获取cpu温度
在C语言中获取CPU温度需要调用操作系统提供的API,因为不同操作系统提供的API不同,所以获取CPU温度的方法也会有所不同。
在Windows系统中,可以使用WMI(Windows Management Instrumentation)来获取CPU温度。具体的代码如下:
```
#include <windows.h>
#include <wbemidl.h>
#include <stdio.h>
#pragma comment(lib, "wbemuuid.lib")
int main()
{
HRESULT hres;
// 初始化COM库
hres = CoInitializeEx(0, COINIT_MULTITHREADED);
if (FAILED(hres))
{
printf("Failed to initialize COM library. Error code = 0x%x\n", hres);
return 1;
}
// 设置COM库的安全级别
hres = CoInitializeSecurity(
NULL,
-1,
NULL,
NULL,
RPC_C_AUTHN_LEVEL_DEFAULT,
RPC_C_IMP_LEVEL_IMPERSONATE,
NULL,
EOAC_NONE,
NULL
);
if (FAILED(hres))
{
printf("Failed to initialize security. Error code = 0x%x\n", hres);
CoUninitialize();
return 1;
}
// 创建WMI服务
IWbemLocator* pLoc = NULL;
hres = CoCreateInstance(
CLSID_WbemLocator,
0,
CLSCTX_INPROC_SERVER,
IID_IWbemLocator,
(LPVOID*)&pLoc
);
if (FAILED(hres))
{
printf("Failed to create IWbemLocator object. Error code = 0x%x\n", hres);
CoUninitialize();
return 1;
}
// 连接WMI服务
IWbemServices* pSvc = NULL;
hres = pLoc->ConnectServer(
_bstr_t(L"ROOT\\WMI"),
NULL,
NULL,
0,
NULL,
0,
0,
&pSvc
);
if (FAILED(hres))
{
printf("Could not connect. Error code = 0x%x\n", hres);
pLoc->Release();
CoUninitialize();
return 1;
}
// 设置WMI服务的安全级别
hres = CoSetProxyBlanket(
pSvc,
RPC_C_AUTHN_WINNT,
RPC_C_AUTHZ_NONE,
NULL,
RPC_C_AUTHN_LEVEL_CALL,
RPC_C_IMP_LEVEL_IMPERSONATE,
NULL,
EOAC_NONE
);
if (FAILED(hres))
{
printf("Could not set proxy blanket. Error code = 0x%x\n", hres);
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1;
}
// 构造WMI查询语句
BSTR bstrQuery = SysAllocString(L"SELECT * FROM MSAcpi_ThermalZoneTemperature");
BSTR bstrWQL = SysAllocString(L"WQL");
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
bstrWQL,
bstrQuery,
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator
);
if (FAILED(hres))
{
printf("Query failed. Error code = 0x%x\n", hres);
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1;
}
// 获取查询结果
IWbemClassObject* pclsObj = NULL;
ULONG uReturn = 0;
VARIANT vtProp;
while (pEnumerator)
{
hres = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturn);
if (0 == uReturn)
{
break;
}
// 获取CPU温度
hres = pclsObj->Get(L"CurrentTemperature", 0, &vtProp, 0, 0);
if (FAILED(hres))
{
printf("Could not get CPU temperature. Error code = 0x%x\n", hres);
pclsObj->Release();
continue;
}
// 将温度值转换为摄氏度
double temperature = vtProp.intVal / 10.0 - 273.15;
// 输出温度值
printf("CPU temperature: %.2f℃\n", temperature);
VariantClear(&vtProp);
pclsObj->Release();
}
// 释放资源
pSvc->Release();
pLoc->Release();
pEnumerator->Release();
CoUninitialize();
return 0;
}
```
在Linux系统中,可以通过读取/sys/class/thermal/thermal_zone0/temp文件来获取CPU温度。具体的代码如下:
```
#include <stdio.h>
int main()
{
FILE* fp = fopen("/sys/class/thermal/thermal_zone0/temp", "r");
if (fp == NULL)
{
printf("Failed to open file.\n");
return 1;
}
int temperature;
fscanf(fp, "%d", &temperature); // 读取温度值
fclose(fp);
// 将温度值转换为摄氏度
double celsius = temperature / 1000.0;
// 输出温度值
printf("CPU temperature: %.2f℃\n", celsius);
return 0;
}
```
Windows 使用第三方库c++编程获取cpu温度
要获取Windows上CPU温度,你可以使用第三方库如OpenHardwareMonitor或CPU-Z,这些库提供了访问硬件信息的API。
以下是使用OpenHardwareMonitor库获取CPU温度的示例代码:
首先,下载OpenHardwareMonitor库并将其添加到Visual Studio项目中。
然后,在代码中引用OpenHardwareMonitorLib命名空间:
```
#include "OpenHardwareMonitorLib.h"
using namespace OpenHardwareMonitor::Hardware;
```
接下来,创建一个控制器对象和计算机对象:
```
Computer computer;
computer.CPUEnabled = true;
computer.Open();
```
然后,遍历计算机对象中的所有硬件,并找到CPU:
```
for (int i = 0; i < computer.Hardware.Count(); i++) {
Hardware^ hardware = computer.Hardware[i];
if (hardware->HardwareType == HardwareType::CPU) {
hardware->Update();
for (int j = 0; j < hardware->Sensors.Count(); j++) {
Sensor^ sensor = hardware->Sensors[j];
if (sensor->SensorType == SensorType::Temperature && sensor->Name == "CPU Package") {
float temperature = sensor->Value.Value;
// do something with the temperature
}
}
}
}
```
在上面的代码中,我们找到了CPU Package传感器,并获取了它的值,该值是一个浮点数,表示CPU温度。
最后,当你完成时,记得关闭计算机对象:
```
computer.Close();
```
完整的代码示例:
```
#include "OpenHardwareMonitorLib.h"
using namespace OpenHardwareMonitor::Hardware;
int main() {
Computer computer;
computer.CPUEnabled = true;
computer.Open();
for (int i = 0; i < computer.Hardware.Count(); i++) {
Hardware^ hardware = computer.Hardware[i];
if (hardware->HardwareType == HardwareType::CPU) {
hardware->Update();
for (int j = 0; j < hardware->Sensors.Count(); j++) {
Sensor^ sensor = hardware->Sensors[j];
if (sensor->SensorType == SensorType::Temperature && sensor->Name == "CPU Package") {
float temperature = sensor->Value.Value;
// do something with the temperature
}
}
}
}
computer.Close();
return 0;
}
```
