Electronic design competition for college students

Now that you have learned the modeling and counting of electricity, it seems that you have the foundation. There are usually three people in a team. Generally speaking, one person is responsible for the design of circuit system, including schematic design and PCB layout. One person is responsible for programming; One person is in charge of the thesis. Of course, the student in charge of the thesis should help the other two students, and even be responsible for defining the framework of the large-scale system, because the thesis can't be written for a few days, and any student who needs help should help. You should train in advance according to the role you will play, but don't divide the work too carefully at the beginning of training. Every student has to operate everything (hardware, software, articles) and then train in the last three months.

If you study hardware, you should be familiar with related drawing and simulation software, such as PROTEL (schematic diagram and PCB layout) and multisim (commonly used for simulation), and familiar with various commonly used components, such as core devices (single chip microcomputer, DSP chip, FPGA, CPLD), ADC (conversion speed and accuracy ...), DAC (conversion speed in Kyoto ...) and capacitor (electrolysis). How big is the withstand voltage ...), resistance (power, accuracy ...), inductance, etc. Students in charge of software should learn the programming controlled by single chip microcomputer (assembly, C……), DSP-related programming languages (C, MATLAB……), FPGA and CPLD(VERILOG, VHDL). Just choose a company to start each device, such as C805 1F series (from SLICONLAB, including ADC, DAC, etc. ), DSP uses TI, FPGA uses XILINX as the development board. Of course, you can also buy it (because it is mainly related to programming, but you can also do it yourself to exercise your hardware development ability). The common way is to design a minimum control system by yourself. If you write a paper, you should search the papers of previous competitions, learn writing methods and highlight the highlights. I won't introduce this much.

When preparing for the start of the competition, try to do all the small topics in each direction and find the direction you are interested in (power supply, electromechanical control, wireless communication, measurement and signal generation, etc.). ), starting from the production of minimum control system training. After finding the direction of interest, we should consider making some small modules that can be used at that time, taking power supply as an example: minimum control system (definitely needed), rectifier and filter module, sampling module, keyboard and display module, power output module and so on. Even if it can't be made into a real object, it is necessary to draw a schematic diagram and test it on the general version. Only the parameters of related components need to be changed during the competition.

The specific competition time should be determined according to the specific competition you participate in. Generally, national competitions will be held in early or middle September. Ask the teacher to help you pay attention to the registration time and competition time. It's too late to prepare now. The result is not important, but the process. Wish you success!
