需要帮助进行微控制器编程以发现汽车发动机的缺陷 [英] Need help for microcontroller programming to find the defect of car engine

问题描述

我是一名即将毕业的学生，​​我们选择了能够检测汽车发动机缺陷的项目，因此我想知道哪种设备适合该项目，以及我们应该在该项目中首先做什么


需要帮助:)

I am a final year student and we have chosen project which detect the defects of a car engine so I want to know that which device is appropriate for this project and what should we do first in this project


Need Help :)

推荐答案

没有更多信息就很难为您提供帮助，但是我的经验告诉我，不可能对汽车发动机进行通用检查".
同样在Modell系列中(即整容后)，有这么多不同的编码芯片.
接下来是获取状态码.它们经常被加密，在更多情况下是不公开的，以读取CAN/MOST代码的工作量很大(如我所说，如果可能的话).

但是我可以想象您的教授(谁考虑过学生可以实现的项目)暗示了OBDII协议?

这里有很多支持ODBII的汽车列表，当然不是完整列表，但另一方面，很难找到兼容的OBDII-USB-Reader的索引"听了(ELM323，ELM327，...). Link是德国人，但您只需要研究一下汽车型号即可.

Hi,

not easy to help you without more information, but my experience tells me that it''s not possible to do a "universal check" of car engines.
There are so many different coded chips, also within the same modell series (i.e. after facelifting).
Next thing is to get the status codes. They are often crypted, in more often case not public, a lot of work to read CAN/MOST-Codes (as I said, if its possible at all).

But I can imagine that your prof (who thought about projects students can realize) alluds to the OBDII-protocol?

Here''s a great list of cars which supports ODBII, of course it''s not a full list, but on the other hand it''s really hard to find such an "index" where also compatible OBDII-USB-Readers are listened (ELM323,ELM327,...). The Link is german, but you just need a look into car models.

哪个设备?那不是第一次，不是很长一段时间.

您需要查看的第一件事是必须与什么设备接口才能监视引擎的当前状况，它们提供多少数据，何时以及如何提供.然后，您可以开始查看输出，存储和...

最后，您可以开始研究处理器了！

但是话虽如此，您可能最终会得到Microchip系列的东西...:laugh:

可能值得联系福特或通用汽车，并询问他们-我不知道他们是否会告诉您任何有用的信息，但这看起来不错！

Which device? That is not first, not by a long ways.

The first thing you need to look at is what device you have to interface with in order to monitor the current condition of the engine, and how much data they provide, and when, and how. Then you can start looking at outputs, and storage, and ...

Finally, you can start looking at a processor!

But having said that, you will probably end up with something from the Microchip range... :laugh:

It might be worth contacting Ford or General motors, and asking them - I don''t know if they will tell you anything useful, but it looks good!

您好，穆罕默德，

首先，您必须定义项目的需求.
我想到了一些要求:

-高处理速度
-便携式设备
-轻松进行数据传输
-易于编程(高级语言，如c#，java，matlab等)
-高性能(如果您有一些复杂的算法，并且需要大量的内存和处理能力)

如OriginalGriff所说，如果您只想读取数据并将其传输到笔记本电脑，那么MicroChip处理器或Arduino就足够了.

如果项目中最重要的事情是性能，并且您需要快速获取和处理数据，那么我建议您使用nini板，例如mini itx或Mini2440 Arm9 S3C2440板(可以在ebay上轻松找到).

最好的问候

Hi Mohammad,

First you must define the requirements for your project.
There are some requirements that come to my mind:

- high processing speed
- portable device
- easy data transfer
- easy to program (high level language such c#, java, matlab, ...)
- high performance (if you have some complex algorithms and you need a lot of memory and processing power)

If you want just read data and transfer it to your laptop, like OriginalGriff said, a MicroChip processor is enough, or a Arduino.

If the most important thing in your project is performance and you need to get and process your data quickly, I suggest a nini board like a mini itx or a Mini2440 Arm9 S3C2440 board (can be easily found on ebay).
