TURN TO THE DESIGN OF A STRAIN TESTING SYSTEM BASED ON LABVIEW

The results of the experiment should be highly generalized, carefully analyzed, and logically presented. We should go to the rough and refined, and keep the truth from the false, but we should not make subjective trade-offs because they do not conform to our own intentions, let alone deceive. Only data obtained during periods of technical inproficiency or instrument instability, data obtained in the event of technical failure or operational errors, and data obtained when the experimental conditions are not met should be discarded.

Moreover, the reason must be noted on the original record when the problem is discovered, and it cannot be arbitrarily eliminated due to irregularities in the summary process. When discarding such data, it is necessary to discard experimental data under the same conditions and in the same period, and not only those that do not suit one's own wishes.

The collation of experimental results should be closely related to the theme, cut the complicated and simplified, some data may not be suitable for this article, can be left for other purposes, do not be hard to piece together into a **. **Jargon should be used as much as possible. If you can use a table, don't use a chart, and if you can do without a chart, it's best not to use a chart, so as not to occupy more space and increase the difficulty of typesetting.

Texts, tables, and figures do not duplicate each other. Special circumstances such as accidental phenomena and unexpected changes in the experiment should be explained as necessary, and should not be discarded at will.

Discuss. 6) - Discussion is one of the more important and difficult parts to write about. It is necessary to take a holistic view of the overall situation, grasp the main controversial issues, and discuss them from the improvement of perceptual understanding to rational understanding.

It is necessary to analyze and reason about the experimental results, rather than repeating the experimental results. It is necessary to focus on discussing the results and opinions in the relevant literature at home and abroad, and express one's own views, especially not avoiding opposing views. ** In the discussion, hypotheses can be put forward and the development ideas of the topic can be proposed, but the proportions should be appropriate, and it cannot be written as "science fiction" or "imagination".

Strain testing capability.

system, so I can decide how to help you. Settle.

First of all, the board card (used to collect data, this is the choice of hardware); Then make an interface (mainly for teachers or other operators); The last time you add the function you need, that is, to write a program, serial communication is what you want to do, even the printer? Data storage, query You can use Write Electron**vi to read electron**vi, and then look at the relevant knowledge more.

To measure the rotational speed, an encoder must be installed on the motor, and the value of the encoder can be read through the counter card. Or the driver of the private server motor uploads the position information through the controller. Based on the design of LabVIEW's motor test system, the specific work is relatively simple.

It is possible to use a single-chip microcomputer for data acquisition and storage, but it is necessary to pay attention to the stored data should not be too large, otherwise it will be replaced by other solutions such as FLSAH.

Temperature acquisition requires PT100 to convert the temperature signal into a current signal 4-20mA Convert the current signal into a voltage signal, such as a precision resistor of 250 ohms in series, so that it changes to a 1-5V voltage signal The voltage signal can be collected by AD7606 and converted to 0-0xffff MCU (STM32 series cheap) Communication (CAN and serial ports are OK, it is recommended to use serial ports to be cheaper) Labview host computer receiving.

What is the communication method with the flow meter 485 or 232.

If it is 232, it can be implemented by calling LabView's related example, Visa about serial port control.

Hello! Whether it's CNKI or Wanfang Data, there are examples!

And most colleges and universities have a free interface!

If you want to prepare a translation for a foreign language, the best way is [Google Scholar].

As for the translation, you can directly Google it, and you can finish it in your own wisps!

Friendly Reminder] ==**Writing Method===

First of all, don't have the idea of graduating right away and spending a little money one last time}

Actually, the original line of nucleus** online is not free for you to metabolize! Who wants to take the time to write this for you? Do you think in your free time that you are providing such a meaningless service to others?

So: it's better to write it yourself. The main reason is that there are too many unreliable factors on the Internet, and if you encounter a scammer, you won't forget it.

The simple way to write ** is to first roughly determine your own topic [this is very clear, which teacher has already determined for you], and then look for a few similar articles on the Internet.

Read through some of the relevant materials to get a general idea of what to do! Look at what other people are writing about this stuff!

Refer to the format of your school's **, make a syllabus, and then show the syllabus to your teacher and then revise it. Once the teacher agrees with your outline, you can add to it!

You can also synthesize these **, copy a part of each **, and dig up a new article! Then replace each part with a sentence or word in your own language, and after the method of changing words without changing meanings, you can't find it on the Internet!

Finally, go to Wanfang and other databases for testing [it's cheap here, only 1 yuan per 10,000 words], and modify the red part again!

Good luck with your completion**!

warning】==

If you confirm to find someone to write on your behalf, you should consider carefully if you pay a deposit!

**If you want to trade, you must be optimistic about his payment time, some are set to [3 days], and people will naturally receive the money after expiration!

I hope to use mine to make children's shoes more eyes!
