Have we learned our skills? Mobilization of electronic design competitions

Looking at your future career direction, there are quality points for awards, in short, participating in the top 10% of grades is more useful, for scholarships.

Of course, you have to pay to pay off.

The electrical design competition requires a lot of extracurricular knowledge and a lot of knowledge that sophomores and juniors can learn, such as digital and analog microcontrollers, which will definitely be used, as well as C language programming, some embedded knowledge, and a lot of extracurricular knowledge, those students who won the national awards are self-taught MCUs and the like in advance, and most of the knowledge is also extracurricular, so you must borrow relevant books to learn by yourself to complete the design!

Analog electricity, digital electricity, microcontrollers, FPGAs, common chips, system design methods, various aspects of theory: communication, digital signal processing, signals and systems, control... A lot.

If one person can't be busy, it's okay to divide the labor among several people. Also prepare a pair of hardware.

Decide early on which direction to do the topic so that you can narrow down the scope of preparation.

Take a look at Guo Tianxiang's "New Concept 51 MCU C Language Tutorial--- Introduction, Improvement, Development, and Expansion Strategy" by Guo Tianxiang Electronic Industry Press. Just look at the article "To the Reader" in front of the table of contents.

I don't know, I'm studying mechanics, not electronics.

Hello classmate, I have participated in similar competitions when I was studying in the past, in fact, to be honest, this experience can leave a good impression on the employer during your job interview, and the purpose of going to college is to contact more aspects in college, so I will help Fengshen when looking for a job. But in the future, the possibility of silver and lead losses is very small. Hope you can help.

1. Power supply: simple CNC DC power supply, DC regulated power supply;

2. Signal source: design and production of practical signal source, waveform generator, voltage control LC oscillator, etc.;

3. High-frequency radio: simple radio remote control system, AM radio radio, short-wave FM receiver, FM radio, etc.;

4. Amplifiers: practical low-frequency power amplifiers, high-efficiency audio power amplifiers, broadband amplifiers, etc.;

5. Instrumentation: simple resistance, capacitance and inductance tester, simple digital frequency meter, frequency characteristic tester, digital power frequency rms multimeter, simple digital storage oscilloscope, low-frequency digital phase measuring instrument, simple logic analyzer;

6. Data acquisition and processing: multi-channel data acquisition system, digital voice storage and playback system, data acquisition and transmission system;

7. Control: water temperature control system, automatic round-trip electric car, simple intelligent electric vehicle, liquid drip speed monitoring device.

The most important aspects of the electronic design competition are the fundamentals of analog-to-digital circuits and microcontrollers. You can first find some simple circuits and improve your soldering skills on the basis of learning basic knowledge. The basic gate circuits of modular diodes, transistors, and digital electricity need to be studied well to know their functions, so as to know how to use them when designing circuits.

In addition, it is necessary to learn the C language well, which is very important in the electronic design competition.

The National Electronic Design Competition for College Students is one of the major discipline competitions advocated by the Ministry of Education, a mass scientific and technological activity for college students, with the aim of promoting the reform of the curriculum system and course content of information and electronics disciplines in colleges and universities. The competition is characterized by close integration with the curriculum system and curriculum content reform of relevant majors in colleges and universities, so as to promote its curriculum teaching, teaching reform and laboratory construction. The content of the competition includes both theoretical design and practical production, so as to comprehensively test and strengthen the theoretical foundation and practical innovation ability of the participating students.

The organization and operation mode of the National Undergraduate Electronic Design Competition is: "first-class hosting, expert-led, student-oriented, and social participation" 16-character policy, in order to fully mobilize the enthusiasm of all parties to participate.

I have participated in two competitions and won the first prize once, and the following is my experience: 1. Keep up with the progress of the class arranged by the school and don't fail; 2. Learn to develop software (Protel, IAR [430 MCU development], Quartusii [FPGA development], CCS [DSP development] This software can be temporarily not learned, multsim,) 3. Divide a system into forward channels, processing parts, and backward channels to prepare. Forward passage needs to be prepared:

Programmable amplifiers, filters (including digital filters), notchs, amplitude stabilization circuits, input signal conditioning circuits, operational amplifiers, AD conversion, DDS modules, etc.; The main preparation of the processor: the minimum system board of FPGA and microcontroller and its programming; The main preparation of backward channels: filters, shaping circuits, frequency measurement circuits, peak detection circuits, D a conversion, etc.

Of course, what I'm talking about are all questions about signal processing, instrumentation and the like, and the rest are power supply and control questions, but the general method is similar. To do control questions, you also need to prepare the information and applications of commonly used sensors. The game is played in groups of three, and you can find a good partner first (which is crucial) and prepare for each person.

The topics of the past ten years to analyze the country should be covered in the above directions, but I think there are more questions in instrumentation. Find more design books to read, usually go to the laboratory to do a little bit of small things to enhance enthusiasm, I suggest that you are now a freshman in the annual competition, whether it is national or provincial to participate, you will know him better. Usually, you can also get the competition questions of previous years to do it, and you won't learn from other people's design plans at the beginning.

I still have a lot of experiences and feelings that I can't say for a while, and that's the end of today.

Analog Electrical, Digital Electrical, Microcomputer Principle, MCU C Language, Assembly Language That's basically it.

First of all, look at the analog electricity, digital electricity, and signal bar Recommend "Electronic Design from Scratch".

The questions of the 2019 National College Student Electronic Design Competition are confidential, and under normal circumstances, they will not be known in advance.

No 19 years of the National People's College Student Electronic Contest is the subway.

I haven't been to this before.

You can directly consult the official customer service to find out.

This question asks, it must be useful, the electric race is a good opportunity to exercise, through the electric race you will learn a lot of very practical things, but also will deeply appreciate the importance of knowledge in books, I just participated, the most important thing is that he can tell you the direction of learning, let you understand what you should learn, what your major does, of course you will learn a lot of knowledge, but also experience the importance of cooperation as a team, if you do not go to graduate school, looking for a job, it is recommended that you still participate, It is even more beneficial for you to find a job, if you are going to graduate school, whether you participate or not depends on whether you have enough time, in short, it is advantageous.

It is useful to find a job. Useful for learning and mastering expertise. You can feel the practical application of your expertise in the e-race.

It's good to do something. There is teamwork, and you don't have to spend money on parts.

Go to the teacher and ask him to teach you, and if he doesn't have time, ask him to introduce you to a few books, read them yourself, and take the initiative.

I looked up information on the Internet, asked the teacher for advice, and I also participated in the discussion.

The basic ones are familiar with the theoretical foundations of through-mode electricity and digital electricity.

Do-it-yourself design, overall layout ability, you can practice a single-chip microcomputer development board first, Wu Jianying single-chip microcomputer development board is suitable for learning.

Use some time to learn how to develop a single-chip microcontroller, and then try to make some small productions by yourself, you can refer to previous entries, ask more questions if you don't understand, and turn over more information, you will learn a lot in this process.
