Then, you must understand that the difficulty and direction of the national electric competition are much more difficult than in the early days. You and your team must have a firm belief and never give up.
There will be cheating in every competition, such as instructing the teacher to design and produce for the competition, or directly looking for an outside master to do it and do a good job in the test. This kind of thing happens too much. So now the comprehensive topic is much higher than the original. On the one hand, team cooperation needs to be improved. On the other hand, the experts of the national expert group want to try to put an end to the gunman's behavior from the perspective of the topic. If a comprehensive topic needs a team of gunmen, the cost will be a bit high.
Then, in your team, you need someone who is relatively comprehensive, has a strong sense of responsibility, is good at communicating with relevant teachers, and is determined to participate in the electric competition and win the prize. The team leader should try his best to provide convenient conditions, such as laboratory, buying components, contacting instruments, books and materials, consulting teachers, going out to make PCB and so on. These contents should bear the brunt. Team leader doesn't mean he has any rights, but he pays more.
Of course, most schools will be selected, and many people will unfortunately be eliminated. Then, sometimes the grouping situation is arranged by the school guidance teacher, and you can contact yourself, but you must get the teacher's consent.
Now, let's talk about the specific preparations.
First, you and your classmates should study hard and study hard. At least you should know the basics.
Second, we need to find information, and we need to know from many aspects which teachers are guiding the competitions in your school in previous years, and who has better grades. These contents should be easy for students in our school to find.
Third, find this teacher and ask him if he will take his students to the competition next year. What is the training plan of the school? Show him your determination and tell him your study status and preparation. Ask him what he needs to prepare and respect the teacher's advice.
Fourth, we should look for the test questions in previous years and see what kind of questions came out in previous years. According to the direction of questions, what are the categories? Generally, there are these kinds of problems: power supply, signal detection and control, signal processing and so on. To analyze what kind of topics your teacher is good at, you should focus on them.
Fifth, we must do more, we must do more. If you can't even use an electric soldering iron and an oscilloscope, why don't you take part in any competition? This will take another 5000 words to start. Let's put it simply.
Several requirements that you must meet:
1. Perfect welding process;
2. Skillful use of various instruments;
3. Identification of common components (types, materials, parameters, etc.). );
4. Usage and pin definition of mass production chips (commonly used operational amplifiers, comparators, digital circuits, AD\DA, power chips, etc.). );
5. The use of single chip microcomputer, speaking of single chip microcomputer. You said that you are studying Guo Tianxiang's tutorial now, which is very practical. His is a finished board, the circuit has been repaired, and it is also very suitable for teaching. But for you, you must be broad-minded and don't be limited by his thinking. At this stage, follow the tutorial first, which is already very good as the teaching content. Tutorials are all about the introduction and use of unit circuits. Later, according to my own learning situation, I designed a system myself, and used common things such as keyboard, monitor and AD\DA in a system. Later, according to the teacher's suggestion, see what MCU you need to choose.
6. I think it should be a matter of detail. Reliability of welding process, layout of circuit, wiring of PCB, placement of test points, installation of circuit, etc. You may be sentenced to death directly. I did well in the school exam, but there was something wrong with the bumpy circuit on the way to the test center. If you can't be pure as fire, you will be in a hurry. One is the first two, and you will die directly. Probably when I participated in the national competition for the first time, a brother's circuit was just turned on, and suddenly a smoke came out of the chip. Then, the huge electrolytic capacitor exploded directly and was directly driven out by the test teacher. Maybe the polarity was reversed when power was applied.
What else can I say when I think of it? You should be prepared first.
In fact, there is a lot of content, so you should take it step by step and see the direction of your topic selection at that time. Now, according to your situation, I can only say a rough idea.
At this time, it is premature and inappropriate to divide the work according to the personal situation of your team members.
The national competition is a very good platform for students majoring in electronic information to learn, communicate and show. He can let you learn a lot, improve your competitiveness, and have the opportunity to get in touch with some practical things. Since there is such an opportunity, we must fight for it!
On the other hand, any school, strong or weak, will have teachers to participate in the national electric competition. Do you think that the award-winning competitions announced by the National Organizing Committee one year after each competition are all students' works? ! What are undergraduates like now? Need I say more about how much they weigh? Of course, there are strong people, but that's only a few.
Therefore, it can be said that winning the competition is directly related to your teacher.
If you can worship a famous teacher, congratulations. Teachers with professional ethics deserve every student's respect for life.
Passionate creation is infinitely wonderful!
Dare you? Where to? creat？ & amp？ Enjoy it!
I wish you good results in the 20 1 1 10th National Electronic Design Competition for College Students.
