好的，接下来我想在您设计系统时尽早开始思考的事情是，我们可以在两个不同的基本位置放置系统接口。
OK the next thing that I want to put in your head something to start thinking about very early when you were designing a system is there are two different basic places where we can put an interface for a system.

一种是专用 HDMI 面板。
One is a dedicated HDMI panel.

所以这基本上是一个你可以把它想象成一台非常有限的迷你电脑的设备。
So this is basically a device you can think about it like a very limited mini computer.

它可能运行与旧手机上类似的操作系统。
It will be probably running a similar operating system to what you might find on an older mobile phone.

因此，像 Windows CD 或类似的东西一样，按照我们今天的标准，它不会是一个非常智能的设备。
So like Windows CD or something along those lines it's not going to be a very smart device by our standards today.

iPhone 会扼杀 HDMI，但这个 HDMI 实际上只是为了一件事而构建的，它可以运行单个应用程序，并且做得很好，并保持运行非常稳定。
An iPhone would kill an HDMI but this HDMI is really just built for one thing it can run a single application and do it pretty well and keep it running very stable.

因此，这些小设备基本上直接内置到电气控制面板中，该控制面板可能会也可能不会物理地安装在机器上。
So these little devices basically get built right into an electrical control panel which may or may not be mounted physically right onto a machine.

所以这个小终端如果你愿意的话它真的只能做一件事。
So this little terminal if you will it can really only do one thing.

它运行 R.H.
It runs R.H.

在我的应用程序中。
in my application.

现在这些太棒了。
Now these are awesome.

他们有一些好处。
They have some benefits.

您知道，每当操作员在机器旁边操作机器时，将界面放在机器旁边会非常有用。
You know whenever an operator is working with the machine right there next to the machine it's very useful to have the interface right beside it.

因此，当我更改屏幕上的某些内容时，我可以看着我的正前方，并且可以看到机器做出响应。
So when I change something on the screen I can look right in front of me and I can see the machine respond.

那真是太完美了。
And that is just perfect.

那就是你想要的。
That's what you want.

另一种方法是，您可以将 HDMI 应用程序放置在专用 HDMI 设备上，您可以将其放置在计算机上，然后您可以使用我们提供的几种不同协议和电缆之一在计算机上的 HDMI 应用程序和跑步机之间进行通信。稍后会讨论。
The alternative is you can put your HDMI application rather than on a dedicated HDMI device you can put that on a computer and you can communicate between your HDMI application on the computer and the running machine using one of a handful of different protocols and cables which we'll be discussing later.

但最终的结果是您拥有一台可以做更多事情的计算机。
But the end result is you have a computer which can now do a lot more.

它可以为操作员提供更大、更稳健的界面。
It can offer a bigger more robust interface for the operator.

它可以记录数据，当然计算机除了运行这个应用程序之外还可以做各种其他事情。
It can log data and of course a computer can do all kinds of other things other than just running this app.

但现在我们造成了一个小问题，即我的应用程序的代理可能会从计算机上物理删除。
But now we've created that little bit of a problem that the agent my application might be physically removed from the machine.

因此从技术上讲，您可以让 HDMI 应用程序在地球的一侧运行，而机器在地球的另一侧运行。
So technically you could have the HDMI application running on one side of the planet and the machine on the other side of the planet.

当进行维护时，事情可能会变得复杂。
Well when it comes time to doing maintenance that can complicate things.

因此，使用 PC 有一些好处。
So there's some benefit to using a PC.

使用物理连接到机器的专用 HDMI 面板有一些好处。
There is some benefit to using a dedicated HDMI panel that's physically attached to the machine.

您可以用叉车将机器运走，HDMI、接口和网络应用程序以及一切都会随之顺利进行。
You can bring in your forklift pick up that machine carry it off and the HDMI and interface and network applications and everything go right along with it.

然而，如果我们回到那个 PC 人，我们可以用我们的界面做更多的事情。
However if we're back on that PC man we can do a lot more stuff with our interface.

我们可以锁定数据，我们可以做更好的趋势分析，我们可以创建报告。
We can lock data we can do better trending we can create reports.

您可以使用一台完整的基于 Windows 的 PC 执行各种操作，但不幸的是，您确实无法使用我的面板中的一个简单的小 H 执行此操作。
There are all kinds of things you can do with a full on Windows based PC that unfortunately you really just can't do with a simple little H in my panel.

现在，为了保护这些面板，有一些非常复杂的 HDMI 设备。
Now in defense of those panels there are some pretty sophisticated HDMI devices out there.

其中一些甚至可以在 Windows 上运行。
Some of them even running for Windows.

但即便如此，那些电脑屏幕类型的设备仍然不具备所有这些功能。
But even still those computer screen kind of devices still don't have all that.

台式电脑必须提供。
A desktop PC has to offer.

他们根本没有足够的硬盘空间来进行真正全面的数据记录。
They simply don't have the hard drive space for really comprehensive data logging.

他们没有所有的连接选项。
They don't have all the connectivity options.

因此仍然存在一些限制，更不用说这些设备的成本相当大了。
So there are still some limitations and not to mention the cost of those devices is considerable.

因此，当您考虑将一个 10 英寸的小屏幕安装到您的设备上时，没有一个 10 英寸的屏幕要花费四、五或六千美元，而与安装在桌面上的合适的 Windows 计算机相比，您可以花四到五美元购买一些东西。 500 美元，这将在我的申请中整天运行 H。
So when you look at something like a little 10 inch screen to mount onto your equipment that no 10 inch screen can cost four or five or six thousand dollars as opposed to a suitable Windows computer to sit on a desktop you can get something for four or five hundred dollars which will run an H in my application all day long.

所以成本又是一个问题。
So again cost that's an issue.

与实际受控设备的距离。
Distance from the actual equipment being controlled.

这是一个问题。
That's an issue.

HDMI 本身的灵活性和功能是另一个考虑因素。
Flexibility and capability of the HDMI itself that's another consideration.

因此，取决于设备是什么、应用程序是什么、其运行环境是什么。
So depending on what the equipment is what the application is what the environment is in which it's operating.

这些是您现在必须开始考虑的一些因素，然后您才能确定系统的所有规格，以决定我是否想要使用这些面板之一还是想要使用基于 Windows 的 PC。
These are some considerations that you have to start making Now before you all the spec out a system to decide you know do I want to go with one of these panels or do I want to go with a Windows based PC.
