PCB有劳设计，本科生普通作业.有兴趣的进来看看
录入：edatop.com 点击：
这个是一个有劳的设计，要价由您出。
说白了吧，这是一份作业，其实自己也可以做，但是最近的考试和拖欠作业太多。所以没有时间做了。我觉得吧，这个对于专业人士来说，绝对是最简单的东西，因为这个教授只要求一周就完成，而且只是一个课程的普通作业。
我这里有一张是原理图，那个是我们教授给我们的示范的原理图，如果需要，可以Q我时，我发给你，但是必须使用expressSCH才可以打开。
我能给您的劳务费绝对不会太少，但是一不会高到哪去。毕竟第一，这是个本科生平时的作业，所以真的是很简单第二，我是个学生，身上能有的钱也不会多到哪去。
我的QQ是369258926，加我时请注明 PCB就可以了。谢谢大家了。
那么具体要求如下。我把要求写为word文档了，有些重要的地方高亮了，方便你一些吧
You have been hired as an intern at a local engineering firm. These folks make subsystems for aircraft flight surfaces. They normally instrument the surfaces for things like temperature and ice build up. However, a question has arisen as to whether their subsystems place any mechanical strain on the primary structures.
They wish to place 16 strain gauges on the rudder they presently have under test. This is on top of the sensors they already have in place. Here are the specs.
? The aircraft manufacturer tells you from experience the strain, epsilon, will not exceed 0.5%.
? You are to use the 28 volt power supply they already have for the other sensors.
? The 28v supply can vary from 20v to 50v.
? All your circuitry should fit on one PCB
? You will use an embedded processor that has a C compiler available
? Your embedded processor is to have less than 50 pins
? Find reliability data (MTBF or FIT) for your processor either online or by contacting the manufacturer.
? Use an IA that has programmable gain or resistor set gain.
? They have had problems in the past with 400 hz noise.
? Your PCB should draw less than two amps.
? Your system is to do a complete scan every second, buffer the data and send to a PC for analysis
? Your PCB is to be mounted on the rudder and the data sent to a PC.
? Use and show components rated from -55C to 85C? (or at least to -40C)
? Show the connections from the embedded processor to your other components.
You are to:
? Locate the components you will need including the strain gauges
? Provide data sheets for all components. Use yellow highlighter on those specs that are ‘significant’ to your design.
? Pick non custom components.
? Lay out a schematic of your system
? Simulate as many subsystems as you can
? Layout a PCB.
? Use appropriate connectors on your PCB You can use SMT, through hole, or a mix.
? Draw up a BOM.
It is strongly suggested you use PCB express schematic capture and PCB express printed circuit layout software. Those two programs work together. If the schematic capture program does not have a component you need, try to find a component that is similar. In the PCB part, it does not care about the functionality of the component, only the physical package.
I will leave the link between your system and the PC up to you. USB? Ethernet? CAN? Wireless?
