[网络连接] 【求助】检测网速然后自动休眠的脚本

435718680

求写个 检测网速并自动系统休眠的脚本，有一个win10平板下载的dontsleep用不了，不能阻止平板休眠。
http://www.softwareok.com/?seite=Microsoft/DontSleep
所以只能手动切换休眠，网上找的命令行
永不休眠
powercfg /change standby-timeout-ac 0
powercfg /change standby-timeout-dc 0
3分钟休眠
powercfg /change standby-timeout-ac 3
powercfg /change standby-timeout-dc 3

求写个脚本检测电脑当前下载速度，当下载速度一直低于某值（20kb）一段时间，比如20分钟，切换为3分钟休眠。
如果脚本运行前能读取当前电脑休眠设置参数powercfg /change standby-timeout-ac 3更好，如启动脚本读取powercfg /change standby-timeout-ac 3则设置powercfg /change standby-timeout-ac 0以免下载时休眠导致中断下载。之后再判断 当下载速度一直低于某值（20kb）一段时间，比如20分钟，切换为3分钟休眠。

可以用performance counter class监控下载速度.

不懂代码呀，以前在百度搜到过vbs监控网卡速度的代码，复制了改一下就能用，现在搜不到了

    你好，谢谢大神帮助，目前可以稳定使用，配合WScript.Sleep 60000 可以实现一分钟一次检测，20分钟休眠，也可以减少窗口打印信息过于密集的问题
    但是，你能不能修改一下，那个打印网速自动识别为kb/s或者mb/s甚至gb/s而且带上单位不用kbps而用kb/s呢？这样显示窗口还可以兼做网速监测。而且我自己修改speed = speed * 8  为speed = speed / 1024 会导致小数点很长，非常难看，最好能去掉小数点后面的数据，方便观测。
    还有就是能不能做个设置用来开启关闭网速窗口？有时候可以不用窗口也行，就在后台运行就可以了，我自己改不出来，  去掉  WScript.Echo "speed = " & speed就运行不成功了。以前找的那个就不用显示窗口可以运行。

    如果都能实现那就完美了，再次感谢大神帮助
