如何演示嵌入式系统的示例？
似乎很多小企业人士都需要一些定制的嵌入式系统，但并不太了解其可能性，也无法完全想象它们。
当我试图解释 Android 可以做什么时，我遇到了同样的问题；人们普遍对我目光呆滞——然后我做了一些演示。不知何故，能够看到某样东西——能够触摸它并玩弄它——人们就会有卡通灯泡的时刻。
即使它不能直接适用于他们，演示也会让他们思考什么对他们有用。
我所说的这种人可能是技术人员，也可能不是技术人员，但肯定很聪明，从零开始建立了一家年营业额数百万美元的企业。
他们的需求各不相同，从 RFID 或 GPS 资产到智能设备，应有尽有。人员跟踪、简单的库存控制系统、显示器、通信，有时是卫星，有时是 VPN 或 LAN（wifi 或 RJ45）。很多都需要一个好的后端数据库和一个网站来显示、查询、数据挖掘……
所以，为了解决这个问题，我正在寻找一个或多个简单的项目，这将导致卡通灯泡片刻。它不需要太复杂，因为那些需要复杂解决方案的人通常精通技术，只需简单的事情即可。展示可以采取哪些措施来简化他们的业务并提高利润。
如果可以包括一些 wifi/RJ45 通信，通过互联网进行通信（例如，不仅仅是连接到单个 PC 的微控制器 - 然后应该与服务器/网站进行通信），那么 RFID 读取器将是很好的很好，确实发生了一些事情（LED、声音等），再加上一些数据库、数据库分析/数据挖掘——一些端到端的东西，最好是双向的。
一位朋友建议使用类似 Rube Goldberg 的装置，将乐高 Mindstorms 连接到本地 PC，但也可以从远程 PC（代表总部）或网站进行控制。这将显示设备的远程控制。也许它可以拾取一些 RFID 标签并移动它们（随机或按命令），代表库存控制（或者可能是工厂或仓库内的员工/资产移动（基于位置的服务/GIS）），然后将其显示出来在网站上，有一些漂亮的图表和图表等。
还有其他想法吗？
如何最好地实施？像 http://www.nerdkits.com/ 这样的微控制器入门风筝之一？也许是一些乐高积木，或类似的机器人套件，一些廉价的 RFID 阅读器……还有其他什么吗？
还有 – 价值 409,600 美元的问题 – 什么是一个好的、有代表性的演示，能够以最少的努力展示尽可能多的功能、尽可能令人印象深刻？ （保持模块化并允许轻松添加功能，因为要覆盖的区域如此之大）
ps 带有 Adroid slate PC 的领带也将受到欢迎
It seems that a lot of small business people have a need for some customized embedded systems, but don't really know too much about the possibilities and cannot quite envisage them.
I had the same problem when trying to explain what Android could do; I was generally met with glazed eyes - and then I made a few demos. Somehow, being able to see something - to be able to touch it and play around with it – people have that cartoon lightbulb moment.
Even if it is not directly applicable to them, a demo starts them thinking about what could be useful to them.
The sort of person I am talking about may or may not be technical, but is certainly intelligent, having built from scratch a business which turns over millions.
Their needs are varied, from RFID or GPS asset & people tracking, to simple stock control systems, displays, communications, sometime satellite, sometimes VPN or LAN (wifi or RJ45). A lot of it needs a good back-end database with a web-site to display, query, data-mine …
So, to get to the question, I am looking for a simple project, or projects, which will cause that cartoon lightbulb moment. It need not be too complicated as those who need complicated solutions are generally tech-savvy, just something straightforward & showing what could be done to streamline their business and make it more profitable.
It would be nice it if could include some wifi/RJ45 comms, communicate across the internet (e.g not just a micro-controller attached to a single PC – that should then communicate with a server/web-site), an RFID reader would be nice, something actually happening (LEDs, sounds, etc), plus some database, database analysis/data-ming – something end-to-end, preferably in both directions.
A friend was suggesting a Rube Goldberg like contraption with a Lego Mindstorms attached to a local PC, but also controllable from a remote PC (representing head office) or web site. That would show remote control of devices. Maybe it could pick up some RFID tags and move them around (at random, or on command), representing stock control (or maybe employee/asset movement within a factory or warehouse (Location Based Services/GIS)), which cold then be shown on the web site, with some nice charts & graphs etc.
Any other ideas?
How best to implement it? One of those micro-controller starter kites like http://www.nerdkits.com/ ? Maybe some Lego, or similar robot kit, a few cheap RFID readers … anything else?
And – the $409,600 question – what's a good, representative demo which demonstrate as many functionalities as possible, as impressively as possible, with the least effort? (keeping it modular and allowing for easy addition of features, since there is such a wide area to cover)
p.s a tie with an Adroid slate PC would be welcome too

您的客户可能会对外观坚固、寻求 RFID 标签的遥控卡车比对乐高机器人反应更好。乐高很酷，但它有一点拼凑在一起的“小孩子”的感觉。
如果您：
我会印象深刻。
这是“最少的努力”吗？我不知道，但我希望，如果这是您正在推销的解决方案类型，那么您已经很好地掌握了如何读取 GPS 和 RFID 设备、如何与 wifi 建立 TCP 或 UDP 连接，如何发送和解码数据包。添加一些简单的图形和数据库查找，就可以了。
关于硬件，我对这些都没有任何第一手经验，但是 GadgetPC Wi- Fi G 套件 + USB RFID 读取器 + USB GPS 接收器看起来是一个很好的实验平台。
Your customers might respond better to a solid looking R/C truck which seeks RFID tags than to a Lego robot. Lego is cool, but it has a bit of a slapped-together 'kiddie' feel.
What if you:
I'd be impressed.
Is it 'least effort'? I don't know, but I'd hope that if this is the type of solution you are pitching, that you already have a good handle on how to read GPS and RFID devices, how to establish a TCP or UDP connection with wifi, how to send and decode packets. Add some simple graphics and database lookup, and you are set.
Regarding hardware, I don't have any first hand experience with any of these, but the GadgetPC Wi-Fi G Kit + a USB RFID reader + a USB GPS reciever looks like a nice platform for experimenting with this.
许多芯片制造商都有现成的演示板。 Microchip 有一些很棒的演示板，用于嵌入式系统上的 TCP/IP 通信。我还没见过 RFID 的。向潜在客户展示其中一些演示可以让他们思考什么是可能的。
Many chip manufactures have off-the-shelf demo boards. Microchip has some great demo boards for TCP/IP communications on an embedded system. I haven't seen one yet for RFID. Showing potential customers some of these demos could get them thinking about what is possible.
