Raspberry Pi Power Supply Check

覆盆子PI电源检查

该脚本旨在评估Raspberry Pi的电源和电缆连接的稳定性。

在运行此脚本之前，请确保已安装Sysbench：

 sudo apt-get install sysbench

运行脚本

 wget https://raw.githubusercontent.com/senhan07/Raspberry-Pi-Power-Supply-Check/main/raspberrypi-power-supply-check.sh
sudo chmod +x raspberrypi-power-supply-check.sh
sudo ./raspberrypi-power-supply-check.sh

如果您的PI是正确的（稳定的电源和质量电缆），则在运行脚本后，您应该得到类似的东西：

 45.6'C 1400 / 600 MHz 1.3813V -
 55.3'C 1400 / 1400 MHz 1.3813V -
 58.0'C 1400 / 1400 MHz 1.3813V -
 60.2'C 1400 / 1400 MHz 1.3813V -
 60.2'C 1400 / 1400 MHz 1.3813V -
 61.1'C 1400 / 1400 MHz 1.3813V -
 61.1'C 1400 / 1400 MHz 1.3813V -
 60.8'C 1400 / 1400 MHz 1.3813V -

如果您的电源无法提供稳定的5V 2.5A或电缆不足，则脚本输出可能表示节流和电压底电压的发生：

 39.7'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 48.3'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 52.1'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 54.8'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 55.8'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 56.4'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 57.5'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 58.0'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 59.6'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
