在物联网核心下为RPi3提供UPS帽子的任何建议？ [英] Any suggestions for a UPS hat for RPi3 under IoT Core?
问题描述
我们的项目是一种医疗设备，内置RPi3驱动触摸屏来控制设备。
Our project is a medical device that has a RPi3 inside driving a touch screen to control the device.
当电源按钮被捣碎时，我们遇到了很多问题几次。 最终SD卡损坏，IoT将不再启动。
We have had many problems when the power button is mashed a few times. Eventually the SD card becomes corrupt and IoT will not boot anymore.
我们正在调查使用UPS帽子的可能性，以便在切换到电源时断开电源后RPi3继续启动备用电池。 UPS还应该留出时间让程序进入"空闲"状态。状态应该是
在几秒钟内，基本上，停止对SD卡的所有读写操作，其中电源关闭不会导致
We are investigating the possibility of using a UPS hat to allow the RPi3 to continue to boot when the power is removed by switching to a backup battery. The UPS should also allow time for the program to get to an "idle" state which should be within a couple of seconds, Basically, stop all read and writes to the SD card where a power shutdown won't cause
单位我发现有一个开关需要按下才能在电源恢复后更换电池。 该单元需要密封，因此不允许访问内部组件。
Units that I have found have a switch that needs to be pressed to enable changing of the battery once power is resumed. The unit needs to be sealed, so no access to the internal components is allowed.
我看到需要以下功能：
- 自动切换USB电源丢失时显示电池。
- Auto switch to battery when USB power is lost.
- 恢复时自动切换回USB电源
- Auto switch back to USB power when resumed
- USB电源可用时为电池充电/充电 电池充满电时停止充电的过充电保护
- Charge / recharge battery when ever USB power is available. Overcharge protection to stop charging when battery is fully charged
- 使用UPS或USB电源时RPi3的通知/查询方法。
- Notification / query method to the RPi3 when using UPS or USB power.
- 查询获取UPS电池电压的方法，我可以计算剩下的电池百分比。 功能很好。
- Query method to get UPS battery voltage, I can calculate % battery left. Nice to feature.
我打算在"安全"状态下使用电池通知正常关闭RPi3 / IoT核心/ UWP。不会损坏SD卡的情况。 我们不打算在UPS上延长运行时间。 这不是
a生命关键设备。
I intend on using the battery notification to gracefully shutdown the RPi3 / IoT Core / UWP when in a "safe" condition that will NOT corrupt the SD card. We don't intend on running for an extended time period on the UPS. This is NOT a life critical device.
获取电池电压可以记录并了解电池是否开始出现故障。
Getting battery voltage gives the ability to record and understand if the battery is starting to fail.
有没有人建议使用UPS？
Does anyone have a suggestion for a UPS?

嗨Mark，
我还没有使用其中一个，但有关Pi论坛的讨论可能有关。

I have not used one of these but there is a discussion on the Pi forums that might relate. https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=105390
此致，
